This STTR project will develop and validate a robust, scalable computational capability for the simulation of weapon-target interactions of interest to the Army. The proposed algorithm is based on the FLIP (Fluid Implicit Particle) - MPM (Material PointMethod) - MFM (Multiphase Flow Method) approach and the CartaBlanca nonlinear solver environment developed at Los Alamos National Laboratory. Car ...

The Phase I program objectives were successfully completed. In addition, novel ideas were developed that will be of use in the Phase II program and in the field of algorithm development and sensor characterization in the laboratory. Work on new algorithmswas initiated to optimize wavelength selection for vapor and aerosol detection, a detailed design for obtaining sensor detection statistics in th ...

The objective of this Small Business Technology Transfer (STTR) project is to develop three-dimensionally integrated packages for mixed DC/RF and optical inputs using micromachining techniques. There are many optoelectronic device designs that have showngreat promise in the research laboratory, but have demonstrated degraded response once packaged. The proposed effort will develop advanced packagi ...

To be commercially competitive, PEM fuel cells have to be able to run on readily available fuels. Fuel reformers are practical, but fuel cell anode catalysts are severely poisoned by small quantities of carbon monoxide from the reformer. Despite mucheffort invested into increasing CO tolerance, desired performance levels have not been achieved.Our Phase I data has demonstrated excellent CO-toler ...

Polyoxometalate (POM) and/or coinage-metal complexes that exhibit dramatic color changes on reaction with chemical warfare agents (CWAs) will be incorporated into cellulose matrices (paper and cotton) by robust electrostatic and covalent bonds to preparelightweight, easy-to-use, color-indicating CWA-detecting tear strips. These strips are expected to show very high sensitivity to CWAs, and thus b ...

Mitochondria are intracellular organelles that regulate a number of vital processes in eukaryotic cells. They are not only the primary sites of energy production but are also the primary source of the harmful reactive Oxygen Species that cause oxidativedamage to the cell. In addition they regulate the critical process of programmed cell death (apoptosis). Thus proper mitochondrial function is crit ...

Mitochondria are the organelles that play a central role in energy production in eukaryotic cells. Besides their bioenergetic function, mitochondria regulate cell death, modulate ionic homeostasis, oxidize carbohydrates and fatty acids, and participate inmultiple other catabolic and anabolic pathways. It is estimated that there are 1000-2000 distinct mitochondrial proteins, many of wich have not y ...

Concrete designs of a novel actuator, which can deliver significantly augmented force and/or stroke relative to conventional actuators, and associated drive electronics and a control system, are focus of our technology development program. The plannedeffort leverages recent work done by Prof. C. S. Lynch of Georgia Tech on modeling and characterization of relaxor single crystals and development of ...

Theoretical investigations and technology developments during last years have created new conceptual approach to design and build a new class of plasma wave electronics detectors of terahertz (THz) wave range. Terahertz radiation corresponds to thefrequency bands of molecular and lattice vibrations in gases, fluids, and solids. THz detectors with higher sensitivity is urgently need for important a ...

Chemical warfare agents with their low vapor pressure can stay on a surface for long periods of time and pose a serious threat to anyone coming into contact with the surface. A standoff sensor that can visualize and identify such a threat is of greatinterest to the US military.Pacific Advanced Technology (PAT) has a technology with the capability of standoff detection and the potential for identif ...
