This Phase I research proposal is directed at demonstrating the feasibility of decontaminating nerve agents on sensitive surfaces and equipment using enzyme-containing polymers. Nerve agent hydrolyzing enzyme polymers have distinct advantages over conventional technologies for agent degradation as they are compatible with biological tissues and wound sites, highly specific for chemical agents, an ...

Ktech proposes to develop a HV2A methodology for the assessment of nuclear weapon effects on new materials that are candidates for inclusion in strategic and tactical military systems. The methodology (1) provides an estimate of the system requirements and operation environments for each application specific material/structure, (2) establishes the critical response modes, (3) provides a framework ...

Cored fiberglass composites are currently being used as structural materials on several Advanced Technology Demonstration (ATD) programs. They are also viable candidates for new designs for the LPD class and DD21 surface ship platforms. The challenge imposed upon these material systems is that not only must they be superior monolithic metal counterparts in structure, they are additionally requir ...

Vinylester resin is the workhorse of the boat and marine industry. This family of resin is low in cost, low in viscosity, chemically resistant, and possesses a cure cycle that ranges from room temperature for methyl ethyl ketone (MEK) peroxide to dicumyl peroxide for elevated cure vinylester . As versitile as these family of resins are, they do suffer shortcomings. Vinylester resins exposed to f ...

This Phase I effort involves synthesis of polymers via enzymatically catalyzed polymerization (ECP). ECP-derived polymers frequently have broad molecular weight distribution with branching, which can be beneficial for ionic conduction. Ionic conductivity approaching 10 -3 S/cm can be demonstrated for ective of this Phase I work is to identify promisi ...

Low-temperature MBE grown GaAs (LT-GaAs) contains a high concentration of excess As which gives rise to ultra-fast carrier-trapping time and excellent radiation hardness. In as-grown layers most of this excess As is in the form of As(Ga) antisite defects, of which only ~1% are ionized. Thermal annealing upon overgrowth with a device structure or during device processing results in a decrease of ...

The goal of this effort is to establish the feasibility and advantages of a new class of wide angle optical field flatteners which exhibit superior resolution and insertion loss when compared with other fiber-based approaches and, unlike the classical Piazzi-Smyth field flatteners, have a nearly unlimited field curvature correction range. This high performance field flattener technology is an ena ...
