Research in silicon photonics has received much attention in recent years for its potential to utilize well developed silicon processing technology. A broad range of linear and nonlinear silicon photonic devices such as modulators, splitters, switches and detectors have been demonstrated. However, the most important challenge in silicon photonics thus far is the difficulty of making electrically p ...

In this program, Omega Optics and the University of Texas at Austin propose to develop an on-chip surface-enhanced Raman scattering (SERS) spectrometer array for single molecule detection. The sensitivity of the SERS spectrometer comes from the 5-nm gap between gold nanowires, which can achieve 108 enhancement factor (EF) for the Raman scattering signals. Especially, these gold nanowires are preci ...

TRACLabs Inc. has worked with NASA to create indoor/outdoor, vision-based leader-following systems for sparse, extra-terrestrial environments. Brown University's Robotics Group has demonstrated leader-following and gesture recognition in high-traffic, dynamic, indoor environments using active lidar sensing. We propose to combine our technologies in order to create a passive sensing system that w ...

Highly scalable parallel random number generators (RNGs) will be developed, evaluated and implemented for use in high performance computing on thousands of multi-core processors and general purpose graphics processing units. The main contributions are: (a) design and implementation of new parallel test methods that capture the inter-stream correlations exhibited in practice and complement the curr ...

The current produced in electrochemical galvanic cells is primarily dependent on the rate of the electrode reactions where the cell's anode is less negative, supplying less energy than thermodynamically predicted, and the cell's cathode is less positive, supplying less energy than thermodynamically predicted. Reduction of electrochemical overpotentials in electrochemical systems has been the prim ...

Agave BioSystems, in collaboration with Professor George Malliaras of Cornell University, proposes to develop a unique and innovative biosensor based on induced luminescence of captured BW bacterial agents and organic light emitting diode (OLED)technology. The system would use an array of bacteriophage engineered to express fluorescent protein in infected BW agents. The specificity of the phag ...

This Phase II STTR proposal describes an activated form of organophosphate hydrolyzing enzyme that, when dissolved in water, forms a covalent bond to skin. In Phase I, a lyophilized preparation of Organophosphate Hydrolase (OPH) from Pseudomonas diminutaretained the capability to couple to skin and to hydrolyze nerve agent surrogates when stored for months at 40¿C. Immobilized enzyme also retai ...

This proposal encompasses a facile method for generating transgenic chickens. Traditionally, the approach to accomplish this has been to target the avian egg or embryo for gene insertion using either viral or 'standard' plasmids as vectors. In contrast,our proposed method introduces two new features, i.e. (1) novel transposon DNA vectors and (2) injection of DNA into the testes of immature males. ...
