The Phase I objective is to demonstrate dislocation reduction in both cadmium telluride (CdTe) and subsequent HgCdTe epitaxial layers grown on silicon substrate using an intermediate nanocrystalline CdTe buffer layer of optimized thickness and size. Nanocrystalline CdTe buffer layer will be deposited on silicon substrate by low cost processing method/s. The method consists of (a) Colloidal synthe ...

This program will create 40 Gbps VCSEL-based micro-transceiver (uTRX) components that operate reliably over the standard military temperature range of -55°C to 125°C in Army environments. uTRXs are low-cost, compact components that can be assembled into the PCB in close proximity to high-performance ASICs using conventional solder-reflow"pick-and-place"assembly. The small PCB footprint and sol ...

The problem of detecting hazardous trace species rapidly and sensitively is a difficult spectroscopic problem. Potentially, this problem might be solved with an elemental detection method such as LIBS combined with a molecular detection method. Laser-induced fluorescence (LIF) might be a candidate for the detection of small molecules, but for larger polyatomic molecules, the resulting fluorescence ...

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 low cost chloroperoxidase can be potentially applicable to the inactivation of chemical agents due to its exceptional stability, broad substrate profile, and high catalytic efficiency. However, the high cost of producing large amounts of CPO is a major obstacle precluding the formulation and field deployment of this enzyme for chemical agent decontamination. Infoscitex Corporation (IST) and ...

Traditional coatings used by the military to camouflage and protect aluminum alloys contain organic solvents (VOCs) and toxic metal corrosion inhibitors (chromates). Gases emitted during application and wastes generated when stripping the metal for recoating create hazardous working conditions and pollute the environment. Appliqués (thin film fluoropolymers with a pressure sensitive adhesive) pr ...

We shall develop an advanced three dimensional simulation capability to compute penetration environments with high fidelity. The strategy will be to develop the next generation of solid mechanics high-performance solvers based on lagrangian formulationsand incorporating all the relevant physical phenomena including contact and friction, thermo-mechanical coupling high strain-rate and material fail ...

Our long-term objective of this project is to develop an integrated system that is capable of categorizing and managing injured combatants in the field of combat trauma care. In this STTR, however, we focus on developing suitable imaging systems that can triage the combatants who are salvageable, assess their immediate potential head and spine injury and determine those with unstable spine injuri ...

Trauma and severe hemorrhage remain the most frequent causes of death in the 1-44 year age group in both the civilian and military settings. Early recognition of shock and prompt institution of appropriate resuscitative measures are widely believed to improve outcome and decrease the progression to multi-system organ failure by virtue of maintaining end-organ perfusion. The physiological response ...

Cortical spreading depression (CSD) is a region of transient electrical and metabolic failure that propagates through peri-lesional brain tissue. Although characteristics of CSD have been shown to be relevant to injury outcome, subdural electrode measurements currently in use restrict monitoring only to patients requiring craniotomy. A portable, noninvasive monitoring device applicable to all pa ...
