VCU receives $2.5M grant to extend battery life development
Virginia Business online
VCU researchers believe they can significantly extend battery life, drive down costs and reduce safety risks by redesigning materials found in lithium-ion batteries, which are commonly used to power smartphones and other electronic devices. The project will be run by Ram B. Gupta, associate dean for faculty research development and a professor of chemical and life science engineering at VCU’s College of Engineering. Gupta and his team will test an approach for synthesizing material for the battery’s cathode.

Method of forming nanoparticles and microparticles of controllable size using supercritical fluids with enhanced mass transfer
US 6620351 B2
The current invention, Supercritical Antisolvent Precipitation with Enhanced Mass Transfer (SAS-EM) provides a significantly improved method for the production of nano and micro-particles with a narrow size distribution. The processes of the invention utilize the properties of supercritical fluids and also the principles of virbrational atomization to provide an efficient technique for the effective nanonization or micronization of particles. Like the SAS technique, SAS-EM, also uses a supercritical fluid as the antisolvent, but in the present invention the dispersion jet is deflected by a vibrating surface that atomizes the jet into fine droplets. The vibrating surface also generates a vibrational flow field within the supercritical phase that enhances mass transfer through increased mixing. Sizes of the particles obtained by this technique are easily controlled by changing the vibration intensity of the deflecting surface, which in turn is controlled by adjusting the power input to the vibration source. A major advantage of the SAS-EM technique is that it can be successfully used to obtain nanoparticles of materials that usually yield fibers or large crystals in SAS method. Microencapsulation via coprecipitation of two or more materials can also be achieved using the SAS-EM technique.
