72905-High speed networks will be required to deliver the large data volumes associated with DOE science experiments. Deployment scenarios for 10 Gb/s enterprise and access networks will require optical interfaces capable of spanning distances from 100 m to 10 km. Presently available 10 Gb/s optical front-ends are not generally applicable because they are either lacking in capability or are too ...

72808-The conversion of cellulosic biomass to commodity products via biological processing could benefit society by improving energy security, reducing greenhouse gas emissions, and promoting rural economies. However, commercial application is impeded by the current absence of low-cost technology to overcome the recalcitrance of cellulosic biomass. This project will develop a strain of Clostridi ...

73089-DOE Office of Defense Nuclear Nonproliferation (NA) applications, especially in the area of software radio, drive wide bandwidths and therefore require high-density super-computing-class I/O, memory, and signal processing capabilities. General-purpose processors do not provide enough performance density to effectively address these applications. The introduction of super-computing boards b ...

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 ...

In the wake of the September 11th attacks and subsequent Anthrax scares, researchers worldwide are working to expand our ability to rapidly assess what poses a terrorism threat to the public. The rapid detection of specific pathogens is required for biod

WE PROPOSE THE DESIGN OF A UNIQUE COMPUTER PERIPHERAL THAT COMBINES DATA, VOICE, AND GRAPHICS COMMUNICATION. THE PURPOSE OF THIS DEVICE IS TO ALLOW ONE USER TO COMMUNICATE WITH ANOTHER USER OVER AN UNCONDITIONED TELEPHONE LINE, BOTHIN VOICE AND DATA. THE PROPOSED DESIGN MAKES USE OF STATE-OF-THE-ART APPLICATION IN DIGITAL SIGNAL PROCESSING AND TELECOMMUNICATION TECHNIQUES. THE UNIQUE FEATURE OF TH ...

THE THERMOTUNNEL ENERGY CONVERTER CAN IN PRINCIPLE PROVIDE AMEANS OF CONVERTING HEAT TO ELECTRICITY WITHOUT MOVING PARTSWHICH IS MARKEDLY SUPERIOR TO PRESENT THERMIONIC AND THERMOELECTRIC CONVERTERS WITH RESPECT TO EFFICIENCY AND POWER DENSITY. FUNDAMENTAL LIMITATIONS OF EXISTING STATIC ENERGY CONVERSION SYSTEMS ARE CIRCUMVENTED IN THE THERMOTUNNEL ENERGY CONVERTER BY USING QUANTUM MECHANICAL TUNN ...

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 ...

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 ...

72603-Many of the cathode materials currently in use in Organic Light Emitting Devices (OLEDs) are metals, such as Mg and Ca, and alloys. In many cases, the migration of these metals to form rough interfaces and hot-spots has lead to reduced lifetimes of the devices. There is a need to develop highly stable cathode materials that have low work function, can be nondestructively coated over large ...
