Arkansas Power Electronics International, Inc. will design and develop a high performance, high voltage ( & gt; 15 kV) SiC MCPM that is low cost, manufacturable, reliable and reworkable. The target utility scale energy storage applications include power conversion systems for grid-tie, solar array, wind turbine, and vehicle-to-grid to aid in load leveling, frequency control, voltage fluctuations i ...

SiC power semiconductors have the capability of greatly outperforming Si-based power devices. Smaller switching and on-state losses coupled with higher voltage blocking capability, and especially its high operating temperature make SiC the ideal semiconductor for high performance, high power density power modules. One major factor limiting the switching speed, and thus power loss of these devices, ...

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 ...

The objective of this Phase I project is to demonstrate feasibility to design and develop novel nanomanufactured multicomponent lubricant additives applicable for engine, especially engineered as additive for enhancing engine economy with at least 3%. This economy will be enhanced through the power of nanosized multicomponent (multi-chemistry/macromolecular) lubricating agents launching into the i ...

Electric vehicles, hybrid electric vehicles, and plugin hybrid electric vehicles (EVs, HEVs, and PHEVs) are emerging technologies that can significantly reduce petroleum usage in the transportation sector. Widespread adoption of electricdrive vehicles will lower automobile operation costs and can significantly decrease emissions of greenhouse gases. However, for these technologies to be successful ...

COAL CONTAINS APPROXIMATELY EQUAL MOLAR AMOUNTS OF HYDROGEN AND CARBON; SYNTHESIS OF LIQUID FUELS OR METHANE REQUIRES AT LEAST TWICE AS MUCH ADDITIONAL HYDROGEN. THE REMOVAL OF LARGE QUANTITIES OF HETERO-ATOM COMPONENTS FROM TAR SANDS OILS AND SHALE OILS REQUIRES LARGE AMOUNTS OF HYDROGEN. HYDROGEN PRODUCED CATALYTICALLY BY THE WATER GAS SHIFT REACTION IS EXPENSIVE, SERIOUSLY OBSTRUCTING THE APPLI ...

KVH INDUSTRIES PROPOSES TO THOROUGHLY INVESTIGATE BOTH CONVENTIONAL AND INNOVATIVE USES FOR THE SELF POWERED VEHICLE DETECTOR (SPVD) AND TO MODIFY THE EXISTING DESIGN, IF REQUIRED, TO MEET THE SPECIFICATIONS OF THE NEW APPLICATIONS. THE OVERALL GOAL OF THE PROPOSED SBIR PHASE IEFFORT CAN BE SUBDIVIDED INTO THREE FUNDAMENTAL OBJECTIVES: RESEARCH INTO THE VARIOUS APPLICATIONS OF SPVD TECHNOLOGY AND ...

PHASE I AIMS TO DEMONSTRATE THE FEASIBILITY OF FABRICATING PREFORMS FOR CERAMIC COMPOSITE SHAPES OF INTEREST TO FOSSIL ENERGY BY USING PROPRIETARY THREE-DIMENSIONAL BRAIDING TECHNOLOGY. HIGH PERFORMANCE CERAMIC COMPOSITES, OPERATING IN EXTREME CONDITIONS OF TEMPERATURE AND CORROSIVE ENVIRONMENT, REQUIRE PREFORM ARCHITECTURES THAT CAN PROVIDE TOUGHNESS, STRENGTH, AND A CAPACITY TO ELIMINATE FAILURE ...

DOWEL BARS HAVE TRADITIONALLY BEEN USED AS AN IMPORTANT LOADTRANSFER MECHANISM ON OUR FEDERAL HIGHWAYS. A SIGNIFICANT PROBLEM OCCURRS WITH THE USE OF THESE BARS DUE TO RUST AND RESULTANT SPALLING AND CRACKING CONCRETE. COMPOSITE REINFORCING BARS (CRB) HAVE BECOME WIDELY USED FOR CRACK CONTROL IN MANY REINFORCED CONCRETE STRUCTURES EXPOSED TO AGGRESSIVE ENVIRONMENTS. A LIMITED AMOUNT OF DATA IS AVA ...
