Nickel/metal hydride batteries are attractive from the standpoint of environmental considerations, their inherent safety and good performance characteristics Presently available Ni/M-H batteries have an energy density of 55 Wh/kg and 178 Wh/L, two to three times that of Ni-Cd batteries. Present state of the art batteries utilize metal hydrides, containing 1-1.1 wt % hydrogen. Development efforts a ...

The objective of this program is to develop an advanced tribology system for the next generation of high-output, low heat rejection (LHR) diesel engines. Engines for the U.S. Army Future Combat System will operate at significantly higher temperatures than today's prototype LHR engines. Surfaces Research proposes a program to develop wear-resistant coatings and engine oils that each contain solid ...

This SOCOM Phase I effort will use a unique combination of new materials to construct a superior and lightweight body armor. The research team brings together innovative technologies and products being developed by three experienced small business: fabric woven from SPECTRA fiber with a Neoprene matrix to prevent spalling; composite body armor products for an NIJ Level III+ System with hardened t ...

In this Phase I effort, Touchtone Research Laberatory will manufacture, test and demonstrate seveal unique attributes of a coal-based carbon foam for use as a fireblock material in laminated composite structures. The carbon foam has several unique attributes, including: hihg thermal insulation properties; high resistance to burning; high compressive strength; it is highly tailorable; easy to mach ...

A material which is stronger than conventional aluminum, less permeable to liquid hydrogen than polymer matrix composites (PMCs), less flammable that PMCs in the presence of liquid oxygen, and can be made into large, complex shapes without an autoclave, would have a significant advantage over current cryogenic tank materials. Touchstone Research Laboratory proposes its ...

A novel medialess dynamic particle filter, initially developed for removal of submicron solid particles from gaseous effluents, could be used to remove sticky liquid aerosols, thereby reducing hazardous waste disposition in military painting operations. This inherently self-cleaning filter, based on the patent-pending Boundary Layer Momentum Transfer (BLMT) concept, would be capable of meeting ne ...

4H-silicon carbide power devices are expected to have 3x higher current densities and 200x lower on-resistance, while still operating up to 350 degree C. This is because of an order of magnitude higher breakdown electric field and a 2-3x higher thermal conductivity of 4H-SiC as compared to Si. Recent advances in 4H-SiC crystal quality, low doped epitaxial uniformity, dopant ion implantation, rea ...

Silicon Carbide is exceptionally well suited for high temperature, high-power electronics. These electronics would be ideal for high-temperature applications for electric combat vehicles, including vehicle propulsion, active protection, electric gun and turret control. Therefore, silicon carbide has been identified as a critical electronic technology for use in future armored vehicles. To fully ...

Emergent Technologies Corp. (ETC) in conjunction with research partners at West Virginia University has developed and recently patented an innovation antenna that promises to revolutionize the science of antenna design, construction and utilization. The antenna, labeled the Countrawound Toroidal Helical Antenna (CTTHA), offers a number of significant advantages over conventional antennas. The CT ...

Geophex has prototyped and field-tested a new broadband electromagnetic sensor that has not only proved its detection capabilities but also indicated a tantalizing possibility that it can discriminated targets and, therefore, substantially reduce the false alarm rate. Empirical evidence from the new sensor, known as the GEM-3, includes large amplitude and phase changes over a bandwidth of 300 Hz t ...
