65805 High rate energy storage devices, such as ultracapacitors, are a critical enabling technology for hybrid electric vehicles (HEV). The best electrode materials for use in electric double-layer capacitors (EDLC) possess three characteristics: (1) high surface area; (2) high electrical conductivity; and (3) surface area easily accessible by electrolyte. While ruthenium-based ultracapacitors ...

65030 Advanced gas turbine engines for energy generation suffer turbine blade failure due to overheating, resulting in loss of energy generation and high repair costs. New in-service diagnostics are required to provide lifetime predictions and warnings for the impending catastrophic failure of high speed rotors that use thermal barrier coatings. This project will develop an on-engine sensor for ...

The overall goal of the proposed program is to provide military personnel with a hand-held analyzer capable of detecting chemical and biological agents, as well as toxic industrial chemicals. This will be accomplished through the use of a newnanocomposite material (metal-doped sol-gel) that enhances analyte specific Raman signals sufficiently to allow identifying and quantifying agents at relevan ...

Terrain data needs on the battlefield are generating greater military requirements for new, rapid feature mapping capabilities. Unfortunately, current methods are woefully inadequate to meet the needs of the modern digitized battlefield in which thecommander must have the ability to rapidly obtain accurate terrain information and topographic products. Terrain Reasoning methods will allow more ra ...

65821 Aircraft measurements of ammonia and nitric acid can provide critical information on the sources and sinks of these atmospheric nitrogen species. This is important in understanding air quality, aerosol formation, visibility, and the impact of energy production and usage on global climate change. This project will develop a compact tunable infrared laser differential absorption spectromet ...

60520 The atmospheric abundance of carbon dioxide and methane have increased dramatically during the industrial era. Since these increases can perturb the global climate, it is vital to understand and quantify the factors controlling them. This is difficult because CO2 and CH4 have a wide range of complex surface sources and sinks, which have both natural and anthropogenic components. H ...

60921 Although there are large uncertainties in the quantification of aerosol particles, they have important effects on visibility, acid deposition, climate, and human health. Organic compounds, generated from energy related activities, are known to constitute a large fraction of the ambient aerosol mass in many locations. The quantification of these compounds is hindered by the lack of re ...

65584 To meet regulatory and personnel health needs, the Department of Energy (DOE) must monitor radioactive isotopes to determine real-time activity levels over long periods of time. Improvements in sensitivity over current detection systems are required to meet present and future regulatory and inspection needs. This project will develop an instrument that will improve detection sensitivity, ...

65458 Scintillation spectrometers, consisting of inorganic scintillation crystals coupled to photomultiplier tubes (PMTs), are an important element of nuclear and elementary particle physics experiments. Performance of the detection systems used in these experiments is often limited by the properties of scintillation detectors available at present. This project will investigate a new scintil ...
