Shannon Director’s Award (1998) from the National Institutes of Health, and Young Faculty Career Enhancement Award (1997) from Alabama NSF-EPSCoR.
He is a Fellow of Alabama Academy of Science (2008) and serves/served on the editorial advisory boards various journals including ACS Sustainable Chemistry & Engineering, Industrial & Engineering Chemistry Research, Nanomedicine: Nanotechnology, Biology and Medicine (2005-07), Journal of Biomedical Nanotechnology, Research Letters in Nanotechnology, and Research Letters in Chemical Engineering. He received the B.E. degree (1987) from Indian Institute of Technology, Roorkee, the M.S. degree (1989) from the University of Calgary, and the Ph.D. degree (1993) from the University of Texas at Austin, all in chemical engineering. During 1993-95, he did postdoctoral work at the University of California, Berkeley. His recent books are: Nanoparticle Technology for Drug Delivery (2006, Taylor & Francis), Solubility in Supercritical Carbon Dioxide (2007, CRC Press), Hydrogen Fuel: Production, Transport, and Storage (2008, CRC Press), Gasoline, Diesel and Ethanol Biofuels from Grasses and Plants (Cambridge University Press, 2010), and Compendium of Hydrogen Energy (Elsevier, 2015).

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.

Particulate vaccine formulations for inducing innate and adaptive immunity
US 20170072051 A1
Disclosed are compositions, kits, and methods for inducing an immune response against an infection or a disease. The compositions typically include biodegradable particles having an average effective diameter that such that the biodegradable particles are phagocytosed by antigen presenting cells when the biodegradable particles are administered to a subject in need thereof. Optionally, the compositions include one or more of an adjuvant, an apoptosis inhibitor, and an antigen. The compositions, kits, and methods may be utilized to induce a cell-mediated response, such as a T-helper cell response, and/or a humoral response against a pathogen or a disease. In some embodiments, the compositions, kits, and methods may be utilized to induce preferentially a Th1 response versus other types of immune responses such as a Th2 response
Halloysite Nanotubes and Uses Thereof for Novel Remediation Techniques
US 20160114303 A1
The creation of novel halloysite-based compositions is disclosed. In one embodiment, the hollow clay nanotubes of halloysite are loaded with nanoscale zerovalent iron particles. The resulting composition provides an effective manner of remediating chlorinated hydrocarbons. In another embodiment, the hollow clay nanotubes of halloysite are imbibed with dispersants such as DOSS and Tween 80 surfactants. The resulting composition stabilizes oil-in-water emulsions and subsequently releases the surfactants, thereby reducing interfacial tension significantly, which allows much smaller droplets to form and thus provides for more effective oil remediation.

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.
