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 ...

Cathodes in proton exchange membrane fuel cells (PEMFCs) that run on hydrogen are coated with a thin layer of conductive ionomer- The ionomer facilitates proton conduction to the costly platinum group metal (PGM) catalyst in the cathode, where oxygen reduction and reaction to form water occurs- Higher catalyst efficiency and lower catalyst loadings are desirable for industry PEMFC cost reductions- ...

C4 olefins are important petroleum refinery and petrochemical plant products- They are used in a variety of downstream processes, such as the production of alkylate fuel for gasoline- About 65 million metric tons of alkylate fuel is produced globally from C4 olefins- Other downstream products are secondary butyl alcohol, maleic anhydride, and butylene oxide, butyl rubber, and methyl methacrylate, ...

Actionable understanding of watershed and ecosystem behavior is required for a wide spectrum of societal and engineering needs by both government entities and commercial entities- These needs include, for example, water resource management, precision agriculture and hydropower- Such actionable understanding requires the ability to numerically model various coupled processes and associated reaction ...

The United States depends on its fleet of nuclear facilities for the clean and reliable generation of electricity- With the increased and growing need of electricity, additional nuclear facilities can provide the solution Generation IV Reactors, such as Advanced Small Modular Reactors (SMR’s) are an upgraded means to nuclear thermal energy production- These SMR’s can provide up to 300 megawatt ...

Xergy and RPI will develop a novel composite membrane that enables electrochemical hydrogen compression at > 1 kg/hour at 875 bar with an energy consumption of 1.4 kWh/kg, given hydrogen input at 100 bar. Phase I of this research will include synthesis of membrane samples, followed by bench-top evaluation of key performance characteristics, including polarization curves, Tafel plots, and evaluatio ...

The Army requires the development of models for improving the state-of-the-art understanding of soil state characteristics in regions with varying observational input datasets. Currently, weather-scale remote sensing, mesoscale standoff sensing, and point-scale in situ sensing provide approximate measurements of near-surface soil moisture at different scales and extents of coverage. In addition, s ...

Bulk InAs(x)Sb(1-x) is an infrared detector material that promises higher quantum efficiency than antimony-based superlattices in the longwave infrared (LWIR). This is due to the longer diffusion length of minority carrier holes in the bulk than in superlattices where they are localized. No native substrate exists for lattice-matched growth of InAs(x)Sb(1-x) material with LWIR bandgaps. So a key c ...

Despite over 100 years of research, decompression sickness (DCS) remains the mission-limiting factor in the design and execution of combat diving operations.Divers may spend over an hour decompressing after spending as little as ten minutes at the target depth.While decompressing, divers are limited in vertical mobility, making then susceptible to detection and threatening their survivability.This ...
