Many contaminated DOE sites are located in arid regions where depth to groundwater is significant and/or contaminants were discharged into a vadose zone through which transport to the groundwater table is dominated by unsteady, unsaturated groundwater flow. The absence of an effective means to monitor vadose zone moisture content in profile has been a persistent impediment to developing and calibr ...

Increased use of Exhaust Gas Recirculation (EGR) combined with engine downsizing has pushed automotive turbocharger compressor operation towards and often beyond its efficient and stable operating boundaries. Much of the drive cycle is spent operating the compressor at low flow rates and low pressure ratios, near the compressor surge line, in an area which is usually of low efficiency. Our prelimi ...

The proposed DoE STTR project will provide a pathway for terrestrial CPV (500 to 700 Suns) multi- junction solar cells that will maintain extremely high efficiencies at realistic operating temperatures. The thrust of the proposed project will adapt an integration approach from MEMS to III-V materials grown lattice-matched to gallium arsenide substrates. The efficiency advantages were found to be s ...

Appareo Systems, LLC, proposes to develop a functional prototype head-mounted position and orientation system (HPOS). The HPOS will be capable of operating in electromagnetic fields of up to 200 volts/meter and will provide at least one degree of accuracy and at least one degree of resolution at a 60 Hz update rate while providing 3 degree of freedom (DOF) information on head orientation, includi ...

Standoff detectors are required to detect IEDs. These detectectors are needed to save the lives of American soldiers. QuantaSpec has developed patent pending methods for long-range, sensitive, and selective standoff detection of explosives. These methods have already demonstrated sensitive remote detection of explosive vapors under previous efforts. QuantaSpec's multidisciplinary team will dem ...

Hybrid Electric Vehicles (HEVs) and plug-in Hybrid Vehicles (PHEVs) require advanced technology capacitors, which must have low cost and the ability to operate at 150oC. However, current 150oC film capacitor solutions are expensive and have lower energy density compared to materials that operate at lower temperatures. Polypropylene Film Capacitors represent a potentially cost effective solution ...

Historically, remediation efforts at DOE contaminated sites have relied on numerical models to integrate laboratory and field characterization data, predict the fate and transport behavior of contaminant plumes, design remediation protocols to mitigate contaminant migration, and analyze data from field remediation results. Of particular concern is the effect of subsurface heterogeneities and thei ...

The design of turbomachinery components is a complex process requiring many steps and hundreds of minute decisions in an iterative process. The design proceeds from engine cycle performance and meanline design through 3D viscous flow calculations (CFD) and finite element structural analysis (FEA). Design studies may traverse this process many times, with routine tasks performed by engineers in a ...

79671S Attempts to produce Carbon Nano Tube(CNT) in large quantities have been fraught with overwhelming challenges due to poor yield, costly fabrication, and the need for the purifying processes required to make them useful in applications. This project will develop an alternative nanoscale carbon material with comparable properties that can be produced cost-effectively and in larger quantities ...

Turbo Solutions Engineering LLC is providing this proposal for a Phase I Small Business Innovation Research Program. The technical objectives are to demonstrate the feasibility of the integration of real-time performance monitoring and diagnostics within a turbopump system, to provide operational status data, and to predict the remaining life of critical components. This Integrated Vehicle Healt ...
