RDX and HMX are cyclic nitramines widely used as high explosives in military applications. The Army recognizes a continuing need for more powerful high explosives that have improved energy density. To increase the energy of nitramine materials further, a highly promising strategy is to modify the inherent crystalline density of the materials by structural substitution of hydrogen atoms with chlor ...

SI2 Technologies, Inc. (SI2) will leverage our expertise in low profile, conformal metaferrite antenna design to develop an efficient antenna that enables transmit and receive of circularly polarized UHF SATCOM. The conformal antenna will be low profile to enable conformal integration to Army platforms such as helicopters and UAVs. In Phase I, SI2 will concentrate on the design and optimization of ...

Boston Engineering"s Advanced Systems Group and Dr. Holly Yanco"s team at the University of Massachusetts at Lowell propose to develop a design science for robot operator interfaces and demonstrate its application through existing design tools and prototype systems that reduce operator training time, maximize the ability of an operator - robot team to maintain synchronization, and provide a baseli ...

There is a growing demand for power electronics that can operate under the high temperature and high power conditions that will be encountered in Hybrid Electric Vehicles (HEVs). As the coolant temperature used to dissipate heat from electronics increases, the operation of power semiconductor devices becomes severely limited in order that the safe operating temperature limit of the semiconductors ...

Terephthalic acid is large volume global commodity chemical used in the production of polyester polymers for applications such as polyester fibers, beverage bottles, and specialty polymers and resins. Terephthalic acid (PTA) is currently produced from hydrocarbon feedstocks by a complex, inefficient, energy intensive process, resulting in poor utilization of hydrocarbon resources, high energy ...

This proposal addresses a critical need to develop low cost packaging solutions to reduce size, weight, and increase performance in hybrid electric vehicle (HEV) and electric vehicle (EV) motor drive power electronics. IGBT (integrated gate bipolar transistor) and inverter/converter devices for HEV/EVs currently use silicon as the primary switching element where junction temperatures cannot exceed ...

The MOxST rare-earth electro winning process is the only known process that is compatible with western environmental sitting regulations at low cost. MOxST & apos;s process potentially replaces seven leaching and acid/base reaction unit operations with a single molten salt electrolysis process that produces a pure oxygen by-product. Taken together, these features can simplify metal ...

Silicon carbide based ceramic matrix composites may become the predominant material system from which reactor core components are manufactured. Manufacturing large, high aspect ratio, components using silicon carbide composite materials presents unique manufacturing challenges to maintain dimensional tolerance and meet the performance needs for in core reactor components. Physical Sciences Inc. wi ...

The proliferation of weapons of mass destruction such as nuclear missiles and dirty bombs are a serious threat in the world today. Preventing the spread of these nuclear weapons has reached a state of heightened urgency in recent years. Neutron detection is an important component of the overall detection techniques used in identifying SNMs. At present, there is a real need for a compact, efficient ...

Neutron detectors, traditionally pressurized He-3 tubes, are a common instrument used in nuclear material accounting within the domestic nuclear fuel cycle. Due to the worldwide shortage and high demand of 3He supply, low-cost alternative neutron detection technologies are required to replace He-3 detectors to ensure public safety and proper material management. Based on Cs2LiYCl6:Ce (CLYC) crysta ...
