There is nothing in this patent about automation or computer controlling the process:
Continuous synthesis of high quantum yield inp/zns nanocrystals

Here are the 5 claims-

1. Continuous-flow method for preparing InP/ZnS nanoparticles conducted in a micro-reaction system comprising at least one mixing chamber connected to one reaction chamber and said method comprising:
a. Preparing an indium precursor solution by mixing an indium salt, a fatty protic alkylamine, a fatty alkylacid and zinc carboxylate with an inert solvent optionally heating up to 50-200° C. to get a clear solution under water and oxygen free atmosphere,
b. Preparing a phosphine precursor solution comprising tris(trimethylsilyl) phosphine in the inert solvent under water and oxygen free atmosphere,
c. Injecting the indium precursor solution in excess to the phosphine precursor solution into the mixing chamber to obtain a reaction mixture, wherein the mixing chamber is a magnetic mixing micro-chamber, optionally at a flow rate from 0.1 ml/min to 10 ml/min,
d. Forwarding and heating the reaction mixture at a temperature from 160 to 320° C., within the reaction chamber until InP core suspension is obtained,
e. Forwarding the core suspension into a mixing chamber and injecting a shell precursor solution comprising a Zn source and a S source to the core suspension and optionally capping ligands into the mixing chamber,
f. Forwarding and heating the suspension at a temperature from 160 to 320° C., optionally 200 to 280° C. for shell preparation within the reaction chamber,
g. Cooling.
2. Method according to claim 1 wherein Zn source and S source is a single source.
3. InP/ZnS nanoparticle obtainable by the method of claim 1.
4. Formulation comprising the nanoparticle of claim 3.
5. Device comprising the nanoparticle of claim 3.
