Method, Device and System for Active Cooling of Cold-Spray Nozzles
Cold Spray technology is a deposition process in which metal powder particles are accelerated by injection into a high-velocity stream of gas at temperatures below their melting point through a de Laval nozzle. However, clogging in the inside of the nozzle during the deposition process presents a significant challenge for this technology. This UMass Amherst invention provides a new method, device and system for active cooling of cold spray nozzles that can effectively prevent clogging and increase the operating life of the nozzles.

Direct Printing of 3-D Microbatteries and High Surface-Area Electrodes
This invention provides highly scalable methods to fabricate 3-D lithium ion microbatteries and high surface-area electrodes for microbatteries. The methods involve imprint patterning nanoparticle-based inks using nanoimprint lithography to form high surface-area electrodes and 3-D microbatteries with well-engineered architectures. The 3-D microbatteries offer superior performance with greatly enhanced capacity and power, and can be rapidly charged and discharged.
