Porous Membranes from Polyelectrolyte Coacervates
This invention demonstrates the use of polyelectrolyte complexes (PSS/PDADMAC) by leveraging the “saloplastic” properties as well as post-process annealing to fabricate sustainable, high-performance filtration membrane. This approach replaces traditional toxic organic solvents with water and salt, which does not only reduce environmental and health hazards but also simplifies the manufacturing process and cuts down on waste management costs.

Polymeric Ammonium Halides to Tune Color Polymer-Perovskite Nanocrystal Composites
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.

Reactive Particles for Cold Spray Coatings
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.
