The team is working on an AF Hub phase II program to develop a new, additively manufactured monolithic ceramic combustor to replace an expensive, long lead time refractory metal component. Silicon Nitride is an ideal material for the component because of its thermal and mechanical properties. The new combustor is to be used in an ESPA class satellite and designed specifically to work with the new AF propellent, ASCENT
Air force gets it. Replace metal components with Si3N4 where it can. The medical industry needed to do the same yesterday! Metal ions are contributing to the respiratory issues we are seeing!
Association between PM2.5-bound metals and pediatric respiratory health in Guangzhou: An ecological study investigating source, health risk, and effect
During 2017-2019, the daily mean concentrations of PM2.5 was 53.39 µg/m3, and the daily mean concentrations of PM2.5-bound metals range 0.03 ng/m3 [thorium (Th) and beryllium (Be)] from to 396.40 ng/m3 [iron (Fe)]. PM2.5-bound metals were mainly contributed by motor vehicles and street dust. PM2.5-bound arsenic (As), cadmium (Cd), cobalt (Co), chromium (Cr)(VI), nickel (Ni), and lead (Pb) were found to pose a carcinogenic risk (CR)
Conclusions: Our findings showed that PM2.5 and PM2.5-bound As, Cd, Co, Cr(VI), Ni, and Pb had adverse effects on pediatric respiratory health during the study period. New strategies are required to decrease the production of PM2.5 and PM2.5-bound metals by motor vehicles and to reduce levels of street dust to reduce children's exposure to these pollutants and thereby increase child health.
This is just environmental pollutants but what about the pollutants corroding into our bodies from metal implants? The same metal implants that amplify EM radiation which means the corroded ions in our bodies are also amplifying EM radiation wherever they are at the time of exposure. To make matters worse, EM radiation increases corrosion of metal implants creating a snowball effect. They really should have looked into titanium as well but its not a metal usually found in environmental pollution.
