Buildings consume 40% of the primary energy used in the United States. Space cooling accounts for approximately 12.7% of that primary energy consumption. The cooling demand is determined largely by two external factors: the temperature and humidity of the outdoor air, and the amount of solar radiation incident on the buildings exterior surfaces. The proposal concerns a technology that is integrate ...

Electricity generation processes burn fossil fuels, generating heat that is then used to produce power in a series of efficiency-robbing mechanical steps. These processes are able to generate a large amount of power, but waste a staggering 50 to 60% of the available heat energy due to technology limitations. Thermoelectric (TE) materials provide an attractive approach for recovering such waste hea ...

NOVA Scientific, Inc., teamed with the Electronics Group of Oak Ridge National Laboratory, proposes to construct very large area Microchannel Plate neutron detectors. The applications of these much larger format detectors will serve an exceptionally broad range of government agencies from neutron scattering detectors for DOE to nuclear material panel detectors for NNSA, and ultimately to nuclear m ...

The DOE Systems Biology Knowledgebase (Kbase) was envisioned to provide a framework to support modeling of dynamic cellular processes of microorganisms, plants and metacommunities. The Kbase will provide the tools and data to permit rapid iteration of experiments that draw on a variety of data types and allow endusers to infer how cells and communities respond to natural or induced perturbations, ...

The key requirement for nanocomposite formation is dispersion of clay particles at nm length scales in polymer matrices, which is not trivial. Such a molecular-level dispersion necessitates complete exfoliation of clay particles, which occurs sporadicallywith the fabrication procedures currently in use. Based on a previously demonstrated concept, we propose to develop a novel nanocomposite fabri ...

Electronics products in applications including mobile communications, work stations, small computers, automotive controls, and aerospace and military weapons systems are moving relentlessly toward smaller, thinner, and lighter formats in lower costpackages. Interconnect density requirements in these products are rapidly outstripping that which is achievable through fabrication of traditional mult ...

Silicon has long been the semiconductor of choice for high-voltage power electronic applications. Recently, SiC has attracted attention because SiC is projected to have better performance than silicon. [1] SiC power switching devices have yet to becommercialized, largely due to SiC crystal defects, most notably the device-killing micropipe defect, which does not permit high total current parts t ...

A random access, solid-state, optical cross-switch capable of 770 channel discrimination in the telecommunications C-band is designed and proven as an alternative to current thin-film WDM devices and as a mechanically robust alternative tomicroelectromechanical (MEMS) WDM devices. The device may be used in multiplexing (mux), demultiplexing (demux), or complete cross-switch configurations, and is ...

The wide-bandgap semiconductors GaN and SiC hold great promise for high temperature and highpower electronic devices. This is due to the attractive properties these materials possess, such as wide energy bandgaps, high breakdown fields, high thermalconductivities, and high saturated electron velocities. In addition, GaN and SiC have adequate electron mobilities and can readily be doped n and p ty ...
