Electric power generation from ambient moisture using microbial nanowires
This invention demonstrates thin-film devices made from electrically conductive protein nanowires (e-PNs) that can generate continuous electric power in ambient environment driven by the self-maintained moisture gradient that forms within the film when exposed to the humidity naturally present in the air. The devices can produce substantial voltages at relative humidity as low as 20%.

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.

Soft and Stretchable Dielectric with Reliable Electrical Performance
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.

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.
