75554B Fuel cells are an efficient, combustion-less, virtually pollution-free source of power. In particular, Proton Exchange Membrane (PEM) fuel cells are ideal for a number of applications, due to their ¿quick¿ warm-up characteristics. However, these fuel cells contain some inherent inefficiencies, which results in waste heat that must be removed rapidly via a coolant ¿ currently, either D ...

DNA microarray technology, in combination with statistical and predictive modeling tools, could be used to evaluate thousands of genes against distinct gene expression patterns induced by chemical/biological agents to provide early identification and speed therapeutic intervention. The overall objective of this Phase II effort is to leverage existing public domain resources and commercial tools t ...

76059S In order to safely remove transuranic waste (TRU) and mixed low-level waste buried in the subsurface disposal areas (SDAs), it is important to anticipate exactly what materials are directly below the surface. This project will develop neutron-based, logging tools that can identify TRU and volatile organic compounds (VOCs) in the vicinity of probe holes, thereby permitting safer retrieval ...

By continuing teaming up with one of the most reputable university teams in THz science and technology, ArkLight proposes to carry out the tasks set for a Phase-II program following our success in Phase I. We are aimed at the further development of novel spectrometers to analyze chemicals in the vapor phase based on accurate measurements of the emission and absorption spectra due to the molecular ...

A STEAMFLOODING/STEAM GENERATION SYSTEM IS PROPOSED FOR DEEP, HEAVY OIL RESERVOIRS. THIS CONCEPT MINIMIZES THE DOWNHOLE HEAT LOSSES, IMPROVES RELIABILITY AND REDUCES THE COST OF STEAM GENERATION. ITS FEATURES WILL MAKE STEAMING OF VERY DEEP WELLS (BELOW 7500 FEET) TECHNICALLY AND ECONOMICALLY FEASIBLE, AND WILL IMPROVE THE ECONOMICS OF SHALLOWER WELL STEAMFLOODING. THIS NOVEL CONCEPT SUPPLIES HEAT ...

A NOVEL CHEMICAL FUEL, FIRED COMBUSTOR IS PROPOSED FOR USE AS A LOW COST HEAT SOURCE TO SIMULATE A CLASS OF NUCLEAR REACTORS, INCLUDING THE SOLID CORE, COLLOID CORE, AND GAS CORE NUCLEAR REACTORS, WHICH OPERATE AT PEAK STAGNATION TEMPERATURES BETWEEN 2000-5000OK. SINCE THIS TEMPERATURE RANGE IS COMPATIBLE WITH NON-EQULIBRIUM, MHD GENERATORS, WE ALSO PROPOSE TO DETERMINE THE FEASIBILITY OF USING A ...

75272B Transmission Electron Microscopy is a technique that allows materials to be analyzed to the nanometer and sub-nanometer scales. The next level of materials analysis will require the ability to perform dynamic experimentation within the microscope, which would require specialized specimen holding technology to perform the desired experiments. This project addresses the treatment of a spec ...

THE OBJECTIVE OF THIS PROJECT IS TO DEVELOP A NEW CLASS OF BIOSENSORS BASED ON THE USE OF COLLOIDAL GOLD DIRECTLY OR DEPOSITED AS A POROUS GOLD FILM. THE KEY TO THE APPROACH ISTHE IMMOBILIZATION OF ENZYMES ON GOLD SURFACES THAT PROVIDE FOR HIGHFLUX, HETEROGENEOUS ELECTRON TRANSFER. THE FEASIBILITY OF CONSTRUCTING THIS NEW CLASS OF BIOSENSORS WILL BE EVALUATED BY THE END OF PHASE I. THE OBJECTIVES ...

75604S The U.S. government sponsors and supports various programs to monitor nuclear explosions through seismic, hydroacoustic, and infrasound data collection stations. These stations are typically deployed in remote areas all over the world. However, current remote data acquisition station technology is limited by (1) poor data quality and reliability and (2) high installation, operation, and ...

75655S The photovoltaics (PV) industry is having difficulty finding enough raw materials to match its rapid growth. In addition, traditional sources of secondary grade polysilicon are no longer readily available at inexpensive prices. Reducing the cost of solar silicon wafers is the key to lowering the price of crystalline silicon solar cells. This project will develop a single-step wafer fabr ...
