Took a few minutes to do some patent searches. It helps to know what one is looking. I was limited to the company name. Did not find the Bayer Chemical patents assigned to QMC. Are they held under subsidiary name?
I did find a 2017 issued patent and a later in 2017 patent application. I saved pdf copies.
There are many possible search parameters, if one has the patent number, or application number or published application number, inventor's exact name, and over a dozen other search parameters.
Continuous synthesis of high quantum yield InP/ZnS nanocrystals
United States Patent 9,577,149
Lu , et al. ISSUED: February 21, 2017
Continuous synthesis of high quantum yield InP/ZnS nanocrystals
Abstract
The invention relates to a continuous-flow synthesis process for the preparation of high quality indium phosphide/zinc sulfide core/shell semiconduting nanocrystals in particular quantum dots (QD) conducted in a micro-reaction system comprising at least one mixing chamber connected to one reaction chamber.
