The US Army needs a method for large scale repair and additive manufacture of Ti-6Al-4V components in support of its light weighting initiative. Cold spray metal deposition technology is a solid-state bonding technique where supersonic powdered metal is deposited on a metallic substrate through adiabatic shearing processes at low temperature. Cold spray offers an ideal solution for the Army’s ne ...

To reach the end user, oil and gas production at the wellhead must be transmitted through the country and distributed to a wide range of customers. This logistical system requires natural gas gathering lines, processing facilities, product storage tanks and lots of other equipment. What results is air pollution caused by industry losses during these operations and the use of continuous or intermit ...

To reduce size, weight, power and cost (SWaP-c), military platforms have been evolving towards more integrated platforms that utilize all available space. For radiating systems, this will require exploring innovative design methods, materials and manufacturing approaches to realize cost-effective, customizable and conformal antennas. An attractive solution to this challenge is offered by additive ...

This project aims to develop a low-cost millimeter-wave (mmW) imaging system for ground vehicles, to operate in combination with a long-wave infrared (LWIR) camera. Such a system will mitigate the challenges of driving in degraded visual environments (DVE) including night time, fog, dust, or smoke by providing real-time image of the vehicle surrounding independent from the presence of naturally oc ...

Future U.S. Army vehicles will require engines with low heat rejection, high power density, lower-friction (15 % reduction), reduced fuel consumption (2-5% lower), and higher durability. Our team, NanoCoatings, Inc. (NCI) and Southwest Research Institute (SwRI), will down-select the most promising coating technologies and coating materials for both piston-rings and cylinder-liners. Our preliminary ...

Fungal skin infections plague active duty servicemembers at elevated rates due to exposure to warm, humid climates, poor skin hygiene, and close-quarters living arrangements. We have developed a novel solution that incorporates an endophytic fungal extract with selective activity against Trichophyton species of pathogens. In addition, the selected compound has negligible impact on the organisms th ...

We propose a new epitaxial growth technology for low-defect SiC substrates based on metallic solution growth of SiC on silicon and SiC wafers. A significant feature of the our approach is the use of epitaxial lateral overgrowth for "defect filtering." In the Phase I proposal, we present arguments that the proposed technology will lead to SiC material of unprecedented quality with respect to defect ...

There is much need for lasers with emission wavelengths in the mid-infrared (2 to 5 microns) for applications that include molecular spectroscopy, environmental and atmospheric trace gas analysis, long haul fiber communications, laser surgery, and atmospheric free-space laser transmission. The Lebedev Physical Institute in Moscow has reported double heterostructure GaInAsSb/GaAlAsSb lasers emittin ...

AstroPower proposes to develop a new high voltage solar cell for photovoltaic linear concentrator arrays based on our thin GaAs solar cell and epitaxial lateral overgrowth technologies and applying lateral segment interconnection techniques. This solar cell design has several advantages which make it ideal for space concentrator systems. These are high system voltage (10 to 500 volts per cell), re ...

Automobile three-way catalyst (TWC) are quite efficient at steady state operatingtemperature typically destroying 98% of incoming hydrocarbons (HCs) and carbonmonoxide (CO). However, up to 80% of emissions occur during the first fewminutes of Federal Test Procedure when the engine is running rich, the engine iscold and TWC has not reached light-off temperature. To significantly reduce HCsand CO ...
