Opto-Electrical Study of Spectrally Enhanced Thin Film Solar Devices

Hajimirza S., Howell J.R., The University of Texas at Austin, US

We report optical and electrical study of a light trapping for efficiency enhancement in thin film amorphous silicon. Solar absorption can be improved inside thin films via surface texturing, plasmonic excitations and thin anti-reflecting coating. [...]

The Retention of Silica Nanoparticles at Oil/Water Interface

Metin C.O., Nguyen Q.P., The University of Texas at Austin, US

We investigate the retention of silica nanoparticles at water/crude oil interface. Silica nanoparticles with three different surfaces (unmodified, surface modified with anionic (sulfonate), or nonionic (PEG) surfactant) are used. Interfacial tension (IFT) measurements provide us [...]

Stability of Aqueous Silica Nanoparticle Dispersions under Subsurface Conditions

Metin C.O., Nguyen Q.P., Lake L.W., The University of Texas at Austin, US

The potential application of nanotechnology has significantly advanced into the upstream oil and gas industry. However, harsh subsurface conditions such as high temperature and saline environment are generally incompatible to most commercially available engineered nanoparticles. [...]

The Next Generation of Proteomic Nanochips for Biomarker Discovery

Hu Y., Tasciotti E., Bouamrani A., Liu X., Li L., Liu X., Ferrari M., The University of Texas at Austin, US

In this study, the nanoporous silica thin films (NSTF) were chosen for the reproducible fractionation and selective binding of the serum-based low molecular weight proteome (LMWP). It has been recognized that the collection of LMWP [...]

Step and Flash Imprint Lithography for the Fabrication of Shape-specific, Enzymatically-triggered, Drug Nanocarriers

Caldorera-Moore M., Glangchai L.C., Shi L., Roy K., The University of Texas at Austin, US

Current concepts in the synthesis of nanocarriers primarily involve the use of polymers or lipids to fabricate self-assembled or emulsion-based particles that are mostly spherical, polydisperse, and release drugs through diffusion or hydrolysis. Although significant [...]

SiRNA for Therapeutic Immuno-modulation: Simultaneous Delivery of Cytokine-targeted SiRNA and DNA Antigens to Dendritic Cells using Polymer Microcarriers

Singh A., Nie H., Ghosn B., Roy K., The University of Texas at Austin, US

RNA interference mediated gene knockdown is a potential immuno-modulatory tool for tuning dendritic cells (DC) activation and function in-vivo. We have developed a novel multi-tiered delivery system for combinatorial administration of SiRNA and plasmid DNA [...]

Efficient siRNA Delivery by Secondary and Tertiary Amine Modified Polysaccharides

Ghosn B., Singh A., Roy K., The University of Texas at Austin, US

As siRNA mediated therapy further develops, the need for biocompatible, effective delivery vectors, especially for mucosal delivery, is apparent. We report here a novel nanocarrier for siRNA delivery via targeted chemical modification of the polysaccharide [...]

Reliability of Atomistic-Continuum Modeling Simulations for Problems in Molecular Statics

Prudhomme S., Bauman JP., Oden J.T., The University of Texas at Austin, US

Multi-scale computational modeling aims at developing systematic techniques for bridging scales between atomistic models and continuum models in order to increase the speed of dynamical calculations. Continuum level models can simulate large volumes of material, [...]
