The objective of this proposal is to further develop IV-VI PbSnSe detectors epitaxially grown on Si substrates. The motivation of fabricating IV-VI detector arrays on Si is based on the following advantages of IV-VI Pb-salt semiconductors. (1) The large dielectric constant helps screen and localize the defect related effects. (2) The epitaxial material on Si is highly uniform, and thus the cutoff ...

The high strength to weight and elasticity properties of spider silk make it of significant interest for the production of advanced fibers for military and civilian applications. Plants may offer the only feasible mechanism to produce quantities of spider silk proteins sufficient to sustain large scale manufacturing of these high performance fibers. Successful implementation of bioengineered spid ...

Hypergolic propellant gels offer improved safety and performance flexibility. However, their longer ignition delays endanger engine health and preclude widespread use. Understanding the physical and chemical paths to ignition can enable improving ignition and realizing favorable IM characteristics of gels. ORBITEC and JHU propose targeted laboratory and modeling experiments to elucidate phenome ...

Mefloquine is known to cause adverse neurological effects, possibly attributable to single nucleotide polymorphisms (SNPs). Our objective is to develop a genetic screen capable of determining the susceptibility of an individual to Mefloquine neurotoxicity. In Phase I, transcriptional profiling of primary neurons exposed to Mefloquine was used to construct an intracellular pathway model to explain ...

Currently, the terrain models in most widespread use consist of surfaces represented explicitly as planar triangular facets connected in a continuous manner with each other (triangular irregular networks or TINs). Generally, these models are "terrain skins," that is, representations of height as a univalent function of two independent lateral variables (such as latitude and longitude). Objects wit ...

This effort will extend the Phase I design, development, implementation, testing and performance evaluation of an automated prototype Multisensor Attributes and Contextual Information-Aided Track Correlation Algorithm. The proposed algorithm integrates the following modules based modified/enhanced existing stand-alone algorithms: a) A basic Multisensor Data Collection and Feature Extraction Module ...

ZCT is a volatile memory forensics capability. In Phase I, Pikewerks implemented cross view detection to identify both known and unknown kernel rootkits; and other activity attempting to subvert the normal operations of the operating system. In Phase II Pikewerks proposes to 1) expand collection of memory to include full RAM hibernation storage and RDMA/DMA, 2) expand characterization and analysis ...

Higher efficiency solar cells are needed to reduce solar-array mass, volume, and cost. This project proposes: (i) Reliable, validated models for simulation, analysis, and design of Quantum Dot Superlattice (QDS) based nano-materials for high-efficiency, radiation-hardened photovoltaic cells and photodetectors; (ii) Verify and demonstrate models by experiments; (iii) Implement novel models in CFDR ...

Warfighters increasingly rely on radio communication equipment to ensure safety, mission effectiveness, and situational awareness. Current military communication gear involves headphones and acoustic microphones. Unfortunately, headphones cover the ears and deteriorate detection and localization of ambient sounds that may be important for tactical situations. An alternative to air conduction is bo ...

Orbital Technologies Corporation (ORBITEC), with the assistance of SRI International under subcontract, propose to develop new and innovative environmentally-benign oxidizers to replace ammonium perchlorate (AP) in solid propellant formulations. These innovative oxidizers will not contain halogens and shall have equivalent or improved performance, reduced water solubility/mobility, and reduced to ...
