High performance computing networks (HPC) require very high data transmission rates with large bandwidth. Fiber optic networks can meet the data transmission and bandwidth requirements. However, new component technology is needed to provide the interface to computer logic and memory systems, with are primarily silicon based electronics. Direct bandgap III-V semiconductor materials such as gallium ...

The modern warfighter faces the constant threat of endemic infections, multi-drug resistant bacteria and Biological Warfare Agents. In order to provide accurate front-line treatment that will curtail the overuse of antibiotics, a rapid and robust molecula

Establish a radiation-aware analysis capability in a commercial EDA design flow that will enable first-pass success in radiation-hardened by design (RHBD) for DoD ASICs in much the same way that existing EDA design suites ensure first pass functionality and performance success of complex ASICs destined for commercial applications. Layout-aware, calibrated single-event radiation models that captur ...

A compact laser driver will allow photoconductive semiconductor switches to be used in small EMP simulator "building blocks" (EMPBB). Combined with a battery powered on-board pulsed power system, these EMPBBs will allow the construction of flexible EMP test facilities with nothing more than a single fiber optic timing connection to each EMPBB.

Despite the dramatic growth of natural gas resources, methane (the major component in natural gas) is underutilized as a feedstock for the production of chemicals and liquid fuels. Currently, methane conversion relies on an indirect two-step gas-to-liquid (GTL) technology. This process is energy intensive and has high operating costs. We propose to develop a new approach to directly convert methan ...

Metal casting is an important manufacturing process and most castings are made by small to mid-sized foundries. Sand molded castings account for 85% of all iron and steel castings produced and approximately 5 out of 30 major casting defects including gas blows and sand burn-on are related to poor sand mold atmosphere control. Mold atmosphere control should become more crucial in the coming years a ...

Neutron scattering is one of the most useful methods of studying the structure and dynamics of matter. Therefore, a number of new large neutron facilities have recently being constructed, upgraded or planned around the world. Examples include the new, 1.4 billion-dollars Spallation Neutron Source (SNS) at DOEs Oak Ridge National Laboratory and upgrades of ORNLs High- Flux Isotope Reactor and N ...

The ability to detect radiological materials at standoff distances of a kilometer or more would be invaluable to national security and nonproliferation efforts. In particular, it is important to be able to distinguish isotopes of uranium and other elements associated with nuclear weapons development and use. Current methods for identifying radiological isotopes require direct sampling. Laser ba ...

As part of its mission to understand the fundamental forces and particles of nature as manifested in nuclear matter, DOE is funding an experiment to measure the electric dipole moment of neutron. This sophisticated experiment tests the standard model by monitoring the response of neutrons in crossed electric and magnetic fields. This Phase I project will investigate a method for measuring the str ...

The Office of Nuclear Energy, fuel cycle research and development program, requires improved radioisotope detectors for spent fuel rod monitoring and process control. Processing spent fuel rods releases large amounts of the fission by-product gas krypton-85 (Kr-85). This beta emitting radioisotope gas has a 10.7 year half-life and must be captured and stored for up to 100 years. The health hazards ...
