This invention demonstrates the leveraging of an ammonium halide-containing copolymer or a guanidium halide-containing copolymer to color tune lead halide perovskite nanocrystals (NCs). These multifunctional ligands boost the photoluminescence quantum yield and facilitate a route to control inter-NC halide exchange kinetics based on binding of the polymer chains to the NC surface and their solvent-responsive aggregation.

This invention demonstrates a novel signal processing technique to deconstruct a wideband input signal into a set of reduced amplitude/bandwidth signals, which are then amplified and digitized to be reconstructed in the digital domain using a minimal set of hardware.

 This invention provides technology for enhanced oil contents and increased seed yield by using a unique combination of seed-specific promoter, terminator, and coding sequences either as a single gene or combination of genes (stacked genes). This technology offers a scalable and sustainable solutions for renewable biofuels energy, agriculture and food production. 

This invention demonstrates a stretchable form of dielectric that maintains its electrical performance even in highly conductive environments for an extended period of time. This is achieved by embedding a layer of liquid metal in the soft and stretchable dielectric materials to effectively stop the diffusions of conductive matters diffusing/penetrating through the polymeric matrix network while maintaining the stretchability.

This invention demonstrates solid or semi-solid microparticles that undergo crosslinking and polymerization upon contacting a substrate to form a coating. The microparticles are maintained in an un-reacted state until delivered using cold spray processes where they are propelled using a gas stream at a pre-determined temperature and velocity. The process does not require volatile organic solvents or aqueous vehicles, nor plural component spray or two component formulations with limited shelf life but still deliver uniform coating.
