'Nanomechanical Oscillators' Could Lead to New Class of Computers
PHYSORG.COM
By Laura Mgrdichian
A schematic drawing (top) and scanning electron microscope image of the nanomechanical oscillator.
Figure courtesy Imran Mahboob.
More than 50 years ago, a graduate student in Japan conceived the “Parametron,” an electrical circuit that could form the basis for digital computers. The concept ultimately fell flat, but recently a pair of scientists gave new life to the idea, and their work could be a first step toward a nanomechanical computer that is based on mechanical rather than electrical operations.

Rather than today's electronic “0” and “1” bits—the most basic pieces of information a computer can store, defined by whether a transistor has a zero or non-zero voltage across it—the Parametron used the response of an electrical oscillator to an applied frequency. The Parametron could only oscillate in two ways, a behavior that was exploited to represent 0's and 1's to enable binary logic.
Computers based on the Parametron were built, but the idea never took off as there were difficulties with power consumption and integration, and the much faster transistor quickly rendered it obsolete.
In the era of nanotechnology, the Parametron has been resurrected using mechanical oscillators. The scientists who have revived its spirit are Imran Mahboob and Hiroshi Yamaguchi of the NTT Corporation in Japan. Their electromechanical oscillator has a bridge-over-gap structure, and it's tiny: The gap is four micrometers deep and the bridge is 260 micrometers long, 84 micrometers wide, and 1.35 micrometers thick.
The bridge and the larger piece of material that contains the gap are made of the widely used semiconductor gallium arsenide (GaAs).
At the each end of the bridge, known as clamping points, there is a sandwich structure: a thin GaAs layer between a gold electrode and a “two-dimensional electronic system,” a general term for a material in which the electrons are confined to a plane.
When an alternating-current voltage that matches the bridge's natural frequency is applied across it, the bridge will oscillate vertically. This physical motion is due to a chain of events that begins with a displacement of atoms in the thin GaAs layer in response to the voltage. This causes the positive and negative charges in the layer to separate, which, in turn, produces a strain across the length of the bridge. The bridge bends slightly, a movement that can be tuned to a resonance frequency—there are more than one—by adjusting the voltage.
These resonance modes can be used to store information as bits. For example, neighboring oscillators with resonances that differ in phase—meaning they do not oscillate in unison—can represent 0 and 1 values.
“This is a highly tunable system, which we expect will make it easily integrable into complex architectures,” says Imran.
A nanomechanical computer based on his and Yamaguchi's concept would likely never be as fast as a transistor-based computer. But it would have some advantages, including being more resilient to electromagnetic shock and more energy efficient. This could make it a good replacement for computers that do not need to be ultra-fast, such as those in appliances, mobile phones, and cars.

Gold nanoparticles are tiny pieces of gold, so small they cannot be seen by the naked eye. Researchers believe gold nanoparticles will be used in cancer detection and treatment, the production of “smart” electronic devices, the treatment of certain genetic eye diseases and the development of “green” automobiles.
While the nanotechnology industry is expected to produce large quantities of nanoparticles in the near future, researchers have been worried about the environmental impact of typical production methods. Commonly, nanoparticles have been produced using synthetic chemicals. Katti’s process, which uses only naturally occurring elements, could have major environmental implications for the future. Since some of the chemicals currently used to make nanoparticles are toxic to humans, Katti’s discovery also could open doors for additional medical fields. Having a 100-percent natural “green” process could allow medical researchers to expand the use of the nanoparticles.
“Typically, a producer must use a variety of synthetic or man-made chemicals to produce gold nanoparticles,” said Katti, professor of radiology and physics in the School of Medicine and College of Arts and Science at MU, senior research scientist at the MU Research Reactor (MURR) and director of the University of Missouri Cancer Nanotechnology Platform. “To make the chemicals necessary for production, you need to have other artificial chemicals produced, creating an even larger, negative environmental impact. Our new process only takes what nature has made available to us and uses that to produce a technology already proven to have far-reaching impacts in technology and medicine.”
The new discovery has created a large positive response in the scientific community. Researchers from as far away as Germany have commented on the discovery’s importance and the impact it will have in the future.
“Dr. Katti’s discovery sets up the beginning of a new knowledge frontier that interfaces plant science, chemistry and nanotechnology,” said Herbert W. Roesky, a professor and world-renowned chemist from the University of Goettingen in Germany.
Katti and his long-time collaborator and colleague, Raghuraman Kannan, assistant professor of radiology, sowed the seeds of Nanomedicine at MU through their groundbreaking discoveries in 2004. MU now has an internationally recognized research program in nanomedicine. The research was funded by grants from the National Cancer Institute and the National Institutes of Health.
Katti’s research in the field of nanomedicine, biomedicine, cancer diagnostics/therapeutics and optical imaging have earned him numerous awards and recognition. The latest honor bestowed upon Katti is the “Outstanding Missourian” award, which he will receive Tuesday, March 4 in Jefferson City. The award is presented as “acknowledgement of the most accomplished citizens of the state of Missouri” and for making an “outstanding contribution to his state or nation.” He is scheduled to receive the award at the beginning of the morning session of the Missouri House of Representatives.
In a recent interview, he expressed his gratefulness for the recognition, but attributes much of the credit to others, including his wife, Kavita Katti, who is a senior research chemist at MU, and his parents in India who supported him in his education.
“I feel excited about the recognition, and I attribute my selection to our institution, my research group and my collaborators,” Katti said. “This award is the culmination of several factors, including departmental leadership, a plethora of outstanding collaborators at MU, the deans and, of course, the chancellor. A faculty member could not possibly succeed just by his or her own efforts. We have been very blessed with this team effort. I am very excited to receive this recognition. I think it speaks highly of our school and of our nanomedicine program.”

Power from Fabrics
Nanowires that convert motion into current could lead to textiles that can generate power.

Georgia Tech researchers have taken an important step toward creating fabrics that could generate power from the wearer's walking, breathing, and heartbeats. The researchers, led by materials-science professor Zhong Lin Wang, have made a flexible fiber coated with zinc oxide nanowires that can convert mechanical energy into electricity. The fibers, the researchers say, should be able to harvest any kind of vibration or motion for electric current.
The zinc oxide nanowires grow vertically from the surface of the polymer fiber. When one fiber brushes against another, the nanowires flex and generate electric current. The researchers described a proof-of-concept yarn in a paper published this week in the journal Nature. They show that the output current increases by entwining multiple fibers to make the yarn.
By the researchers' calculations, a square meter of fabric made from the fibers could put out as much as 80 milliwatts--enough to power portable electronics. The development could make shirts and shoes that power iPods and medical implants, curtains that generate power when they flap in the wind, and tents that power portable electronics devices.
In 2007, Wang and his colleague the 2007 TR 35 winner Xudong Wang (no relation) built a zinc oxide nanowire array that generated direct current when exposed to ultrasonic vibrations. The piezoelectric nanowires stood on an electrically conducting substrate that acted as an electrode. The other electrode was a platinum-coated silicon plate with parallel peaks and trenches carved on its surface. (See "Nanogenerator Fueled by Vibrations.") When the ultrasonic waves pushed the electrodes together, the nanowires bent and produced current.
In the new work, the researchers have substituted the rigid, zigzag electrode with a flexible one. They convert some of the bendable fibers into electrodes by applying a thin layer of gold to them. These gold-plated fibers act as flexible electrodes.
The researchers entangle a gold-coated fiber with an uncoated fiber. When the fibers are pulled back and forth with respect to each other, the individual gold-plated nanowires push and bend the uncoated nanowires, generating current.
The flexibility of the fibers brings the idea of wearable, foldable energy sources closer to fruition, says Charles Lieber, a chemistry professor at Harvard University. The flexibility is also crucial for harvesting energy from extremely small ambient motion, says Thomas Thundat, who studies nanoscale biological sensors at Oak Ridge National Laboratory. Entwining the flexible fibers, he explains, leads to very close contact between the gold-coated and the uncoated nanowires. As a result, small motions, such as a light wind or walking movements, make the coated and uncoated nanowires brush against each other and generate current.
"The idea is ingenious," says Min-Feng Yu, a mechanical-science and engineering professor at the University of Illinois at Urbana-Champaign. "It's like you have millions of nanogenerators outputting electricity simultaneously, each at maximum performance.".
The generator's ability to capture small movements makes it especially useful for powering biological sensors, Thundat says. Microscale sensors can be implanted in the body to measure such things as cancer biomarkers and glucose. But chemical batteries are bulky compared with the tiny sensors, and they have a limited lifetime. "Implanted sensors based on [the fiber nanogenerator] concept could use blood pressure or muscle movement for operation," Thundat says.
The Georgia Tech advance would not be possible without the simple but highly innovative process the researchers have used to make the fibers, Lieber points out. Zhong Lin Wang and his colleagues first cover a polymer fiber with a 100-nanometer-thick zinc oxide layer. They immerse the fiber in a reactant solution at 80 °C, which results in nanowires growing vertically from the surface. Then the researchers use a final trick to keep the nanowires firmly attached to the fibers while keeping the fibers flexible. They dip the fibers in tetraethoxysilane, a liquid used in weatherproofing and protective coatings. The tetraethoxysilane forms two coatings: one between the fiber and the zinc oxide layer, and another on top of the zinc oxide layer.
This tetraethoxysilane coating makes the fiber robust. The zinc oxide layer did not crack or peel off even when the fiber was twisted. The nanowires also stayed put after the researchers continuously brushed two fibers against each other for 30 minutes. The fibers will have to last even longer and have higher output power in order to be used practically, Wang says.
Power-generating shirts might still be out of reach for most. At this point, the fabric might be affordable for the military for use in tents and shoes, says Wang, but "it is probably too expensive for you and me to buy."

Machines 'to match man by 2029'
2008-02-16 19:14:00
By Helen Briggs
Science reporter, BBC News, Boston
Tiny machines could roam the body curing diseases
Machines will achieve human-level artificial intelligence by 2029, a leading US inventor has predicted.
Humanity is on the brink of advances that will see tiny robots implanted in people's brains to make them more intelligent, said Ray Kurzweil.
The engineer believes machines and humans will eventually merge through devices implanted in the body to boost intelligence and health.
"It's really part of our civilisation," Mr Kurzweil explained.
"But that's not going to be an alien invasion of intelligent machines to displace us."
Machines were already doing hundreds of things humans used to do, at human levels of intelligence or better, in many different areas, he said.
Man versus machine
"I've made the case that we will have both the hardware and the software to achieve human level artificial intelligence with the broad suppleness of human intelligence including our emotional intelligence by 2029," he said.
We'll have intelligent nanobots go into our brains... to make us smarter
Ray Kurzweil
"We're already a human machine civilisation; we use our technology to expand our physical and mental horizons and this will be a further extension of that."
Humans and machines would eventually merge, by means of devices embedded in people's bodies to keep them healthy and improve their intelligence, predicted Mr Kurzweil.
"We'll have intelligent nanobots go into our brains through the capillaries and interact directly with our biological neurons," he told BBC News.
14 CHALLENGES FACING HUMANITY
Make solar energy affordable
Provide energy from fusion
Develop carbon sequestration
Manage the nitrogen cycle
Provide access to clean water
Reverse engineer the brain
Prevent nuclear terror
Secure cyberspace
Enhance virtual reality
Improve urban infrastructure
Advance health informatics
Engineer better medicines
Advance personalised learning
Explore natural frontiers
The nanobots, he said, would "make us smarter, remember things better and automatically go into full emergent virtual reality environments through the nervous system".
Mr Kurzweil is one of 18 influential thinkers chosen to identify the great technological challenges facing humanity in the 21st century by the US National Academy of Engineering.
The experts include Google founder Larry Page and genome pioneer Dr Craig Venter.
The 14 challenges were announced at the annual meeting of the American Association for the Advancement of Science in Boston, which concludes on Monday.

The February 14 issue of the journal Nature details how pairs of textile fibers covered with zinc oxide nanowires can generate electrical current using the piezoelectric effect. Combining current flow from many fiber pairs woven into a shirt or jacket could allow the wearer’s body movement to power a range of portable electronic devices. The fibers could also be woven into curtains, tents or other structures to capture energy from wind motion, sound vibration or other mechanical energy.
“The fiber-based nanogenerator would be a simple and economical way to harvest energy from physical movement,” said Zhong Lin Wang, a Regents professor in the School of Materials Science and Engineering at the Georgia Institute of Technology. “If we can combine many of these fibers in double or triple layers in clothing, we could provide a flexible, foldable and wearable power source that, for example, would allow people to generate their own electrical current while walking.”
The research was sponsored by the National Science Foundation, the U.S. Department of Energy and the Emory-Georgia Tech Nanotechnology Center for Personalized and Predictive Oncology.
The microfiber-nanowire hybrid system builds on the nanowire nanogenerator that Wang’s research team announced in April 2007. That system generates current from arrays of vertically-aligned zinc oxide (ZnO) nanowires that flex beneath an electrode containing conductive platinum tips. The nanowire nanogenerator was designed to harness energy from environmental sources such as ultrasonic waves, mechanical vibrations or blood flow.
The nanogenerators developed by Wang’s research group take advantage of the unique coupled piezoelectric and semiconducting properties of zinc oxide nanostructures, which produce small electrical charges when they are flexed. After a year of development, the original nanogenerators – which are two by three millimeters square – can produce up to 800 nanoamperes and 20 millivolts.
The microfiber generators rely on the same principles, but are made from soft materials and designed to capture energy from low-frequency mechanical energy. They consist of DuPont Kevlar fibers on which zinc oxide nanowires have been grown radially and embedded in a polymer at their roots, creating what appear to be microscopic baby-bottle brushes with billions of bristles. One of the fibers in each pair is also coated with gold to serve as the electrode and to deflect the nanowire tips.
“The two fibers scrub together just like two bottle brushes with their bristles touching, and the piezoelectric-semiconductor process converts the mechanical motion into electrical energy,” Wang explained. “Many of these devices could be put together to produce higher power output.”
Wang and collaborators Xudong Wang and Yong Qin have made more than 200 of the fiber nanogenerators. Each is tested on an apparatus that uses a spring and wheel to move one fiber against the other. The fibers are rubbed together for up to 30 minutes to test their durability and power production.
So far, the researchers have measured current of about four nanoamperes and output voltage of about four millivolts from a nanogenerator that included two fibers that were each one centimeter long. With a much improved design, Wang estimates that a square meter of fabric made from the special fibers could theoretically generate as much as 80 milliwatts of power.
Fabrication of the microfiber nanogenerator begins with coating a 100-nanometer seed layer of zinc oxide onto the Kevlar using magnetron sputtering. The fibers are then immersed in a reactant solution for approximately 12 hours, which causes nanowires to grow from the seed layer at a temperature of 80 degrees Celsius. The growth produces uniform coverage of the fibers, with typical lengths of about 3.5 microns and several hundred nanometers between each fiber.
To help maintain the nanowires’ connection to the Kevlar, the researchers apply two layers of tetraethoxysilane (TEOS) to the fiber. “First we coat the fiber with the polymer, then with a zinc oxide layer,” Wang explained. “Then we grow the nanowires and re-infiltrate the fiber with the polymer. This helps to avoid scrubbing off the nanowires when the fibers rub together.”
Finally, the researchers apply a 300 nanometer layer of gold to some of the nanowire-covered Kevlar. The two different fibers are then paired up and entangled to ensure that a gold-coated fiber contacts a fiber covered only with zinc oxide nanowires. The gold fibers serve as a Shottky barrier with the zinc oxide, substituting for the platinum-tipped electrode used in the original nanogenerator.
To ensure that the current they measured was produced by the piezoelectric-semiconductor effect and not just static electricity, the researchers conducted several tests. They tried rubbing gold fibers together, and zinc oxide fibers together, neither of which produced current. They also reversed the polarity of the connections, which changed the output current and voltage.
By allowing nanowire growth to take place at temperatures as low as 80 degrees Celsius, the new fabrication technique would allow the nanostructures to be grown on virtually any shape or substrate.
As a next step, the researchers want to combine multiple fiber pairs to increase the current and voltage levels. They also plan to improve conductance of their fibers.
However, one significant challenge lies head for the power shirt – washing it. Zinc oxide is sensitive to moisture, so in real shirts or jackets, the nanowires would have to be protected from the effects of the washing machine, Wang noted.

The march of the 'grey goo' in nanotechnology Frankenfoods
By SEAN POULTER -
Last updated at 10:26am on 2nd January 2008
Alert over the march of the 'grey goo' in nanotechnology Frankenfoods
A breed of Frankenfood is being introduced into human diet and cosmetics with potentially disastrous consequences, experts said last night.
Academics, consumer groups and Government officials are warning that the arrival of nanotechnology threatens dangerous changes to the body and the environment.
The particles it uses are so small - 80,000 times thinner than a human hair - that they can pass through membranes protecting the brain or babies in the womb.
Nano health supplements, such as antioxidants, are already on the market while the first of hundreds of new foods are expected to arrive in the next 12 months.
However, the products are being introdeduced without any regulation or independent assessment to ensure they are safe - mirroring the controversy over the launch of GM foods ten years ago.
Some critics have talked of the threat of the creation of a "grey goo" of tiny particles with hidden harmful properties.
Prince Charles has said it would be "surprising" if the technology did not "offer similar upsets" to thalidomide - the morning sickness drug that caused children to be born with deformed limbs.
Professor Vicki Stone, Professor of Toxicology at Napier University in Edinburgh, is concerned about unforeseen side effects.
"We know very little about the ability of nanoparticles to move around the body, to accumulate or to be excreted, or their potential to cause toxic effects in organs," she said.
However, nanotech advocates have remarkable claims for the technology. For example, foods are in development that are said to stave off the aging process.
On a more trivial level, they suggest it would be possible to create a fizzy drink that changes flavour according to the number of times the can is shaken.
The consumer group Which? is about to launch a nanotech campaign arguing that consumers need to be consulted on the risks and benefits before it is too late.
The food and farming department Defra has published an independent report which admits there are serious gaps in safety data.
It warns: "There could be very significant implications for business and the wider community if potential risks are not identified and managed before any harm to the environment or human health may be done."
The report - Characterising the Risks Posed by Engineered Nanoparticles - states there is a shortage of research money.
It says the resulting absence of basic information about the particles means "it will be difficult or impossible to develop any general understanding of nanoparticle toxicology".
The report adds: "Transfer across biological barriers - e.g. to the brain or foetus - should be studied. Research into how long these tiny particles persist in the body is urgently needed."
It warns that work assessing human toxicology is being hamstrung by "profound difficulties in accessing relevant funding for these longer term projects".
Research by Which? found six out of ten people (61 per cent) have never heard of nanotechnology.
Sue Davies of Which? said: "The benefits that nanotechnologies can offer consumers are really exciting.
'But before the market is flooded with products, it's crucial the Government addresses the lack of scientific understanding about how some nanoparticles behave."
The European Food Safety Authority last year held a conference on the future of food.
Dr Donald Bruce, an expert on food and ethics, told delegates that the arrival of nanotech foods has many similarities with GM products.
US corporations attempted to introduce GM before an effective safety regime could be established.
"One of the things to ask is do we need the benefits claimed by the producers?' he said. 'Also there is the underlying notion that we are tampering with nature."
Environment minister Phil Woolas admitted there were gaps in knowledge, but denied the Government was failing to provide enough research cash.
Tiny particles that have generated great hopes and growing concerns
Nanotechnology involves using a substance in particles that are so small that the substance takes on new properties.
The name of the technology comes from the size of the particles - one nanometre in diameter - a millionth of a millimetre. Reduced to this size, materials can suddenly show very different and unexpected properties.
For example, an opaque substance such as copper becomes transparent, or an inert metal such as platinum becomes a catalyst and triggers chemical reactions.
Advocates argue that such particles can be organised to work together to deliver specific effects in a piece of equipment or in the human body.
They can be used to build miniature hard drives that have an immense memory, so allowing further miniaturisation and sophistication of products such as computers and mobile phones.
Washing machines have been developed that release silver nanoparticles that will kill bacteria in dirty washing.
Sun creams have been created so they become transparent rather than chalky white.
In medicine, it is claimed that nanotechnology will allow the creation of drugs that reach and treat a problem quickly.
Manufacturers are working on nanotech foods and supplements that are also designed to deliver specific health benefits.
Similarly, firms are working on developing anti-ageing foods, where nanotech particles associated with renewing the skin from the inside could be included in everyday products such as yoghurt, spreads or breakfast cereals.
The technology promises huge riches for firms which develop winning applications.
One of the first group of nanoparticles being utilised are fullerenes - tiny hollow carbon balls and tubes. They are very heat resistant, strong and conduct electricity.
The football-shaped C60 fullerene is being used in some anti-ageing products. The creams are said to reduce fine lines and firm the skin.
C60 has some antioxidant properties in that it kills the rogue chemicals which damage cells. However, a high dose can itself damage cells.
Some nano particles are known to mimic the harmful effects of asbestos on the lungs. Consequently, they have the potential to trigger lung cancer if inhaled.

The Year in Nanotech: Thursday, January 03, 2008
Better batteries and super-sticky glues are becoming possible because of nanomaterials.
By Kevin Bullis
Nano Power
Nanowires and carbon nanotubes are proving valuable for generating and storing energy. Researchers have shown that nanowires can convert vibrations into electricity. (See "Nanogenerator Fueled by Vibrations" and "A New Nanogenerator.") Other nanowires can generate power from light. (See "Tiny Solar Cells.") Carbon nanotubes could be useful for extracting more power from cheap solar-cell materials. (See "Cheap Nano Solar Cells.")
Nanotechnology could also greatly improve batteries. MIT researchers made fibers out of viruses coated with functional materials. The fibers could lead to textiles that collect energy from the sun, convert it into electricity, and store it until it's needed. (See "Virus-Built Electronics.") At the end of the year, Stanford researchers published research showing that silicon nanowires can significantly increase the storage capacity of battery electrodes.
Making Objects Invisible
Theorists have predicted a new class of materials that could render objects invisible. The materials work because they interact with light in unusual ways. Now a number of researchers are beginning to put those theories into practice, making rudimentary invisibility cloaks by controlling the micro- and nanostructure of materials. In addition to making things disappear, such materials could be useful for patterning tiny features for computer chips or for novel antennae for communications. (See "Invisible Revolution," "Superlenses and Smaller Computer Chips," "How to Make an Object Invisible," and "Invisibility Made Easier.")
Materials That Stick to Nothing--or Anything
Teflon pans are easy to clean. But a new super self-cleaning material actually causes oil to bounce off. (See "No More Thumbprints.") Another material--this one transparent--could be used to keep windows fog and oil free. (See "Self-Cleaning, Fog-Free Windows.")
Other researchers are developing supersticky materials. They have made structures out of carbon nanotubes that are like the structures on geckos' feet that allow the lizards to climb walls. They've also made glues similar to the proteins that allow mussels to stick to nearly anything, even underwater. (See "Climbing Walls with Nanotubes," "Nanoglue Sticks Underwater," and "Glue That Sticks to Nearly Everything.")
Flexible Electronics Coming to Market
Electronics patterned on flexible substrates that could be used for roll-up displays have previously been demonstrated in the lab. Now products are on the way. In February we described the plans of two companies to manufacture flexible electronics. (See "Plastic Electronics Head for Market.") One of the companies has now actually started production on a flexible-display device.
Meanwhile, researchers are developing methods for making flexible electronics with higher performance. (See "Printing Cheap Chips" and "Expandable Silicon.")
Tiny Memory
Novel approaches to storing data could lead to memory chips as much as a hundred times more compact than today's devices. These include materials that change structure (see "Novel Nanowires for Faster Memory") and ones that grow atoms-thick wires (see "Terabyte Storage for Cell Phones") in response to tiny electronic signals. Researchers at IBM are developing memory chips that exploit newly understood physical mechanisms to provide a cheap and fast alternative to hard drives and flash memory. (See "IBM Attempts to Reinvent Memory.")

Solar cells of the future
A new material, nano flakes, may revolutionise the transformation of solar energy to electricity. If so, even ordinary households can benefit from solar electricity and save money in the future.

If researcher Martin Aagesen’s future solar cells meet the expectations, both your economy and the environment will benefit from the research. Less than 1 per cent of the world’s electricity comes from the sun because it is difficult to transform solar energy to electricity. But Martin Aagesen’s discovery may be a huge step towards boosting the exploitation of solar energy.
"We believe that the nano flakes have the potential to convert up to 30 per cent of the solar energy into electricity and that is twice the amount that we convert today," says Martin Aagesen who is a PhD from the Nano-Science Center and the Niels Bohr Institute at University of Copenhagen. During his work on his PhD thesis, Martin found a new and untried material.
"I discovered a perfect crystalline structure. That is a very rare sight. While being a perfect crystalline structure we could see that it also absorbed all light. It could become the perfect solar cell," says Martin. The discovery of the new material has sparked a lot of attention internationally and has led to an article in Nature Nanotechnology.
"The potential is unmistakeable. We can reduce the solar cell production costs because we use less of the expensive semiconducting silicium in the process due to the use of nanotechnology. At the same time, the future solar cells will exploit the solar energy better as the distance of energy transportation in the solar cell will be shorter and thus lessen the loss of energy," says Martin Aagesen who is also director of the company SunFlake Inc. that pursues development of the new solar cell.

Nanowire battery holds 10 times the charge of existing ones
Stanford researchers have found a way to use silicon nanowires to reinvent the rechargeable lithium-ion batteries that power laptops, iPods, video cameras, cell phones, and countless other devices.

Lithium-thionyl Batteries - Wide Selection of Lithium-thionyl Batteries, 10 year Shelf Time www.all-battery.com
The new version, developed through research led by Yi Cui, assistant professor of materials science and engineering, produces 10 times the amount of electricity of existing lithium-ion, known as Li-ion, batteries. A laptop that now runs on battery for two hours could operate for 20 hours, a boon to ocean-hopping business travelers.
"It's not a small improvement," Cui said. "It's a revolutionary development."
The breakthrough is described in a paper, "High-performance lithium battery anodes using silicon nanowires," published online Dec. 16 in Nature Nanotechnology, written by Cui, his graduate chemistry student Candace Chan and five others.
The greatly expanded storage capacity could make Li-ion batteries attractive to electric car manufacturers. Cui suggested that they could also be used in homes or offices to store electricity generated by rooftop solar panels.
"Given the mature infrastructure behind silicon, this new technology can be pushed to real life quickly," Cui said.
The electrical storage capacity of a Li-ion battery is limited by how much lithium can be held in the battery's anode, which is typically made of carbon. Silicon has a much higher capacity than carbon, but also has a drawback.
Silicon placed in a battery swells as it absorbs positively charged lithium atoms during charging, then shrinks during use (i.e., when playing your iPod) as the lithium is drawn out of the silicon. This expand/shrink cycle typically causes the silicon (often in the form of particles or a thin film) to pulverize, degrading the performance of the battery.
Cui's battery gets around this problem with nanotechnology. The lithium is stored in a forest of tiny silicon nanowires, each with a diameter one-thousandth the thickness of a sheet of paper. The nanowires inflate four times their normal size as they soak up lithium. But, unlike other silicon shapes, they do not fracture.
Research on silicon in batteries began three decades ago. Chan explained: "The people kind of gave up on it because the capacity wasn't high enough and the cycle life wasn't good enough. And it was just because of the shape they were using. It was just too big, and they couldn't undergo the volume changes."
Then, along came silicon nanowires. "We just kind of put them together," Chan said.
For their experiments, Chan grew the nanowires on a stainless steel substrate, providing an excellent electrical connection. "It was a fantastic moment when Candace told me it was working," Cui said.
Cui said that a patent application has been filed. He is considering formation of a company or an agreement with a battery manufacturer. Manufacturing the nanowire batteries would require "one or two different steps, but the process can certainly be scaled up," he added. "It's a well understood process."

A giant step toward infinitesimal machinery
2007-11-07 02:23:00
What are the ultimate limits to miniaturization? How small can machinery--with internal workings that move, turn, and vibrate--be produced? What is the smallest scale on which computers can be built?
With uncanny and characteristic insight, these are questions that the legendary Caltech physicist Richard Feynman [profile] asked himself in the period leading up to a famous 1959 lecture, the first on a topic now called nanotechnology. In a newly announced global Alliance for Nanosystems VLSI (very-large-scale integration), researchers at Caltech's Kavli Nanoscience Institute (KNI) in Pasadena, California, and at the Laboratoire d'Electronique et de Technologie de l'Information-Micro- and Nano-Technologies (CEA/LETI-MINATEC) in Grenoble, France, are working together to take the pursuit of this vision to an entirely new level.
For about three decades after Feynman's lecture, scientists paid little heed to what was apparently viewed as his fanciful dreams in this regard. But more recently, particularly in the past two decades, the field of nanotechnology has been solidly established. Underlying this is an immense amount of careful research, carried out in laboratories worldwide-work that has been realized one advance at a time.

Nanotubes to knit bulletproof armour
Carbon nanotubes are being probed to see if they are the world's most bulletproof materials.
2007-11-06 01:05:00
Australian researchers Professor Liangchi Zhang and Dr Kausala Mylvaganam from the University of Sydney [profile] report on the bullet-bouncing ability of carbon nanotubes in the current issue of the journal Nanotechnology.
"The nanotube absorbs energy from the bullet and the bullet speed reduces," says Zhang, an engineer with the university's Centre for Advanced Materials Technology.
"Then the nanotube tries to recover elastically, and transfer back the energy to the bullet."
Most bulletproof materials are made of ultra high-strength polymers like Kevlar, Twaron or Dyneema fibres.

Nanotech will replace disk drives in 10 years, researcher says
2007-11-05 02:01:00
Nanotechnology will replace magnetic disk drives in iPods, laptops and servers within five to 10 years, making them more durable, lighter and faster.
That's according to Michael Kozicki, a researcher at Arizona State University [profile] who is developing ways to store data in nanowires instead of as electrons in cells. He's also researching ways to stack multiple layers of memory on top of a single layer of silicon.
All of this, Kozicki said, would mean dramatic advances in storage, as well as dramatic differences in the way we use our favorite devices.
"Someday you'll store all your music, movies, photos and favorite TV shows on something the size of an iPod. It'll all be right there," said Kozicki. "Nanotechnology will replace all the disk drives in the world. Sure, we could create a terabyte thumb drive, but if you could do that, why would you use magnetic disks that are everywhere from iPods to servers to data farms? If you drop a device, it could wreck the fragile disc drive. Not with this, though."
If device manufacturers can get rid of disk drives, laptops and MP3 players would be significantly more durable, faster and lighter, according to Kozicki. They also would boot up immediately and have much better memory capacity.

Could nanotechnology revolutionize natural gas industry?
2007-10-31 00:35:00
Nanotechnology could revolutionize the natural gas industry across the whole lifecycle from extraction to pollution reduction or be an enormous missed opportunity, claim two industry experts writing in Inderscience's International Journal of Nanotechnology. They suggest that nanotechnology could help us extract more fuel and feedstock hydrocarbons from dwindling resources. However, industry inertia and a lack of awareness of the benefits could mean a missed opportunity.
According to Saeid Mokhatab and Brian Towler of the Chemical and Petroleum Engineering Department, at the University of Wyoming [profile], in Laramie, there are many opportunities for the industry to exploit nanotechnology. However, there is a traditional lack of innovation in the exploration and production sector, a perception of high costs, new risks, and a general lack of awareness of the benefits of nanotechnology.
The researchers have now described the potential benefits of nanotechnology, which could change that perception. Mokhatab and Towler point out that nanomaterials, such as nanotubes or engineered porous minerals, might be used in the gas field or other source to improve the efficiency of extraction of a wide variety of hydrocarbon fuel compounds and chemical feedstocks.

Nanowire manipulation could lead to hand-held supercomputers
2007-10-23 17:41:00
Researchers have been working on nanowires and microchips so tiny that they could be used to build supercomputers that could fit in the palm of your hand. Hopefully, the nanowires will eventually lead to small, powerful gadget such as hand-held PCs, mobile phones as powerful as laptops, and medical advances.
The group of engineers, with members from the University of Edinburgh in Scotland [profile], the Karlsruhe Institute of Technology in Germany and the University of Rome in Italy, will have their results published in an upcoming issue of Science.
The researchers studied the behavioral properties of nanowires--which are more than 1,000 times thinner than a human hair--and investigated how the wires react and respond to exterior forces compared with conventional wires.
"What we found is when we made these wires smaller and smaller they started to behave in a very funny way," researcher Michael Zaiser told the BBC News.

'World's smallest radio' unveiled
2007-10-19 02:42:00
US scientists have unveiled a detector thousands of times smaller than the diameter of a human hair that can translate radio waves into sound.
According to a University of California team, the study marks the first time that a nano-sized detector has been demonstrated in a working radio system.
Made of carbon nanotubes a few atoms across, it is almost 1,000 times smaller than current radio technology.
Peter Burke and Chris Rutherglen incorporated the microscopic detector into a complete radio system.

Invisibility Made Easier
A new method for creating metamaterials that bend light in unusual ways may bring practical applications closer.
By Kevin Bullis
In the past year, the media have been abuzz with talk of an exotic class of materials, called metamaterials, that could be used to make flat and distortion-free lenses, powerful microscopes, and even cloaking devices that make objects invisible. But versions of the materials suitable for practical applications have been difficult to make. Now researchers at Princeton University have demonstrated metamaterials that are both higher performing and much easier to manufacture, perhaps bringing these applications closer to reality.
"It's quite an important step," says Igor Smolyaninov, a research scientist at the University of Maryland who works with metamaterials. "It's much less expensive than anything else that people are doing."
Light passing from one ordinary material into another bends slightly--think of how a straight stick in water looks bent--but light passing into a metamaterial bends in the opposite direction. Metamaterials thus have what's called a negative index of refraction. A lens made from such a material wouldn't have to be curved. (It's the curvature of an ordinary lens that enables it to focus incoming light.) Metamaterials could also be used to route electromagnetic waves around an object, rendering it invisible. Already, researchers have demonstrated a cloaking device that makes objects invisible to microwaves, and others have created materials that negatively refract electromagnetic waves in the visible part of the electromagnetic spectrum. But until now, metamaterials have had to be patterned with intricate shapes smaller than the wavelength of light they're meant to manipulate. Consequently, materials that work with light of microscopic wavelengths, such as infrared and visible light, have been difficult to make. Because of the way they produce negative refraction, existing metamaterials have also had a strong tendency to absorb light, making them impractical for use in optics.
The materials developed at Princeton retain the property of negative refraction, yet they're much easier to make. Rather than requiring intricate structures, such as the split rings used in the microwave cloaking device, the materials can be made simply by stacking up extremely thin layers of semiconductor material. What's more, that stacking can be done by the same tools now used to make semiconductor materials for lasers used in telecommunications, says Claire Gmachl, the Princeton researcher who led the work. The new materials consist of alternating layers of indium gallium arsenide and aluminum indium arsenide, and they're tuned to work in the infrared region of the spectrum.
Like other metamaterials, the new materials affect light differently than ordinary materials do because they are made of structures significantly smaller than the wavelength of the light passing through them. In this case, however, it is the layers of semiconductors themselves that are thinner than the wavelength of light. Consequently, a wave passing through the material encounters multiple layers at once, responding to them as if they were a single material with properties quite unlike those of either semiconductor in isolation.

Hitachi achieves nanotechnology milestone for quadrupling terabyte hard drive
2007-10-16 03:00:00
TOKYO -- Hitachi, Ltd. (NYSE:HIT) (TOKYO:6501) [profile] and Hitachi Global Storage Technologies (Hitachi GST) announced that they have developed the world's smallest read-head technology for hard disk drives, which is expected to quadruple current storage capacity limits to four terabytes (TB) on a desktop hard drive and one TB on a notebook hard drive.
Researchers at Hitachi have successfully reduced existing recording heads by more than a factor of two to achieve new heads in the 30-50 nanometer (nm) range, which is up to 2,000 times smaller than the width of an average human hair (approx. 70-100 microns). Called current perpendicular-to-the-plane giant magnetoresistive1 (CPP-GMR) heads, Hitachi's new technology is expected to be implemented in shipping products in 2009 and reach its full potential in 2011.
Hitachi will present these achievements at the 8th Perpendicular Magnetic Recording Conference (PMRC 2007) to be held October 15-17, 2007 at the Tokyo International Forum in Japan.
"Hitachi continues to invest in deep research for the advancement of hard disk drives as we believe there is no other technology capable of providing the hard drive's high-capacity, low-cost value for the foreseeable future," said Hiroaki Odawara, Research Director, Storage Technology Research Center, Central Research Laboratory, Hitachi, Ltd. "This is an achievement for consumers as much as it is for Hitachi. It allows Hitachi to fuel the growth of the 'Terabyte Era' of storage, which we started, and gives consumers virtually limitless ability for storing their digital content."
Hitachi believes CPP-GMR heads will enable hard disk drive (HDD) recording densities of 500 gigabits per square inch (Gb/sq. in.) to one terabit per square inch (Tb/sq. in.), a quadrupling of today's highest areal densities. Earlier this year, Hitachi GST delivered the industry's first one-terabyte hard drive at 148 Gb/; the company's highest areal density shipping in products today is in the 200 Gb/ range. These products use existing head technology, called TMR2 (tunnel-magnetoresistive) heads. The recording head and media are the two key technologies controlling the miniaturization evolution and the exponential capacity growth of the HDD.
Cutting Through the Noise -- The Strongest Signal-to-Noise Ratio
The continued advancements of HDDs requires the ability to squeeze more, and thus, smaller data bits onto the recording media, necessitating the continued miniaturization of the recording heads to read those bits. However, as the head becomes smaller, electrical resistance increases, which, in turn, also increases the noise output and compromises the head's ability to correctly read the data signal.
High signal output and low noise is what is desired in hard drive read operations; thus, researchers try to achieve a high signal-to-noise (S/N) ratio in developing effective read-head technology. Using TMR head technology, researchers predict that accurate read operations would not be conducted with confidence as recording densities begin to surpass 500 Gb/sq. in.
The CPP-GMR device, compared to the TMR device, exhibits less of an electrical resistance, resulting in lower electrical noise but also a smaller output signal. Therefore, issues such as producing a high output signal while maintaining a reduced noise to increase the S/N ratio needed to be resolved before the CPP-GMR technology became practical.
In response to this challenge, Hitachi, Ltd. and Hitachi GST have co-developed high-output technology and noise-reduction technology for the CPP-GMR head. A high electron-spin-scattering magnetic film material was used in the CPP-GMR layer to increase the signal output from the head, and new technology for damage-free fine patterning and noise suppression was developed. As a result, the signal-to-noise ratio, an important factor in determining the performance of a head, was drastically improved. For heads with track widths of 30nm to 50nm, industry-leading S/N ratios of 30 decibels (dB) and 40 dB, respectively, were recently achieved with the heads co-developed at Hitachi GST's San Jose Research Center and Hitachi, Ltd.'s Central Research Laboratory in Japan.
Recording heads with 50nm track widths are expected to debut in commercial products in 2009, and those with 30nm track widths will be implemented in products in 2011. Current TMR heads, shipping in products today, have track widths of 70nm.
The Incredible Shrinking Head
The discovery of the GMR effect occurred in 1988, and that body of work was recognized just last week with a Nobel Prize for physics. Nearly two decades after its discovery, the effects of GMR technology are felt more strongly than ever with Hitachi's demonstration of the CPP-GMR head today.
In 1997, nine years after the initial discovery of GMR technology, IBM implemented the industry's first GMR heads in the Deskstar 16GXP. GMR heads allowed the HDD industry to continue its capacity growth and enabled the fastest growth period in history, when capacity doubled every year in the early 2000s. Today, although areal density growth has slowed, advancements to recording head technology, along with other HDD innovations, are enabling HDD capacity to double every two years.
In the past 51 years of the HDD industry, recording head technology has seen monumental decreases in size as areal density and storage capacity achieved dizzying heights. The first HDD recording head, called the inductive head, debuted in 1956 in the RAMAC -- the very first hard drive -- with a track width of 1/20th of an inch, or 1.2 million nm. Today, the CPP-GMR head, with a track width of about one-millionth of an inch, or 30nm, represents a size reduction by a factor of 40,000 over the inductive head used in the RAMAC in 1956.
Notes
1 CPP-GMR: As an alternative to existing TMR heads, CPP-GMR head technology has a lower electrical resistance level, due to its reliance on metallic rather than tunneling conductance, and is thus suited to high-speed operation and scaling to small dimensions.
2 TMR head: Tunnel Magneto-Resistance head
A tunnel magneto-resistance device is composed of a three layer structure of an insulating film sandwiched between ferromagnetic films. The change in current resistance which occurs when the magnetization direction of the upper and lower ferromagnetic layers change (parallel or anti parallel) is known as the TMR effect, and ratio of electrical resistance between the two states is known as the magneto-resistance ratio.

Nanocrystals could light the way to using LEDs to replace the lightbulb
2007-09-27 22:34:00
Thomas Edison's lightbulb has ruled the world's lighting for more than a century, but numerous researchers are trying to replace the incandescent bulb with more energy-efficient solid-state lighting. One problem has been producing bright white light. To address the problem, D.D. Sarma, a materials scientist at the Indian Institute of Science [profile], in Bangalore, has made tiny crystals of semiconductor material that, when coated onto a light-emitting diode (LED), give off a white glow just the right color for illuminating a living room. So far, it's only a weak light, but Sarma hopes to make it much brighter.
Sarma says that his approach gives better control over the whiteness and is simpler than other research efforts that use nanocrystals to produce white-light LEDs. Sarma grows tiny crystals of cadmium sulfide. He then paints them onto an LED that emits ultraviolet wavelengths, and the crystals produce the mix of colors that we perceive as white light. It's the extremely small size of the nanocrystals--each crystal is only five nanometers in diameter--that gives them their remarkable properties, says Sarma.
Single-color LEDs have largely taken over for lightbulbs in uses such as traffic signals. There's a big push to replace incandescent and fluorescent bulbs for general illumination as well. Sandia National Laboratory [profile] estimates that if half of all lighting is based on LEDs by 2025, the world would use 120 gigawatts less electricity, saving $100 billion a year and cutting the carbon-dioxide emissions from power plants by 350 megatons annually.
