  • Patent number: 9932233
    Abstract: A continuous reaction system (CRS) allows a method to prepare quantum dots (QDs) in a continuous manner with high precision. The CRS pumps a plurality of reagent fluids into one or more mixing sites to form a reaction fluid that is carried through a heating chamber at elevated pressures to carry out hydrothermal growth of the QDs. The pumps and heating chamber are controlled with a high precision by employing a detector downstream of the heating chamber to provide a signal that is dependent on the composition and size of the QDs. The signal is provided to a signal processor that provides a signal that control the flow rates and temperature parameters in the system. The QDs produced in this manner are consistent in size and composition and can be of a single semiconductor composition or can be core-shell QDs with a shell semiconductor formed on a core semiconductor.

  • Publication number: 20180026259
    Abstract: A composite electrode is a composite of conductive materials of at least a first material and a second material, wherein the first material undergoes a parasitic reaction in a region where the second material is stable, and the first material and second material are stable at the first material's nominal voltage. An exemplary electrode is a cathode comprising lithium manganese oxide (LMO) and lithium iron phosphate (LFP).

  • Patent number: 9731013
    Abstract: An electromagnetic radiation activated device comprises a property changing material and at least one functionalized fullerene that upon irradiation of the functionalized fullerenes with electromagnetic radiation of one or more frequencies a thermally activated chemical or physical transformation occurs in the property changing material. The thermal activated transformation of the property changing material is triggered by the heating or combustion of the functionalized fullerenes upon their irradiation. The device can include a chemical agent that is embedded in the property changing material and is released when the material is heated by the functionalized fullerenes upon irradiation.

  • Patent number: 7592001
    Abstract: An electroless method of forming high aspect ratio metal particles includes the steps of mixing a metal or metal salt with at least one acid to form an acidified metal halide salt solution, and mixing the solution with a supersaturated sol to form a sol comprising solution. Metal cations provided by the acidified metal salt are reduced to form a plurality of high aspect ratio metal particles. Instead of using a sol, an organic compound can be oxidized to generate the reducing agent. A metal comprising particle assembly includes a plurality of high aspect ratio metal platelets having an aspect ratio of a major dimension averaging from 10 to 200 times a nanoscale minor dimension of the platelet. The platelets can be used for nail polish, eye liner or the cores for medical delivery vehicles.
