Next generation network applications will require high, dynamically-stable transport throughputs at the application level, in order to support such tasks as computational monitoring and steering on supercomputers, massive wide-area data transfers between storage systems, and remote instrument control. However, the current shared IP infrastructure is unsuited for providing the unimpeded stable ban ...

Improved methods of neutron detection are needed not only for nuclear physics research but also for international control of weapons and neutron based therapies in medical applications. He-3 tube-based neutron detectors and planar solid-state neutron detectors are the two currently available technologies for thermal neutron detection. Although He-3 tube-based neutron detectors have efficiencies ...

Novel Li ion batteries with higher energy and power densities, as well as improved stability, are required for use in hybrid/electric vehicles,HEVs, and plug in HEVs, as replacements for the heavier, larger nickel metal hydride batteries. However, Li ion batteries suffer from several problems including performance degradation and safety issues. Promising nanomaterial anodes are being developed t ...

The DOE FutureGen program aims to demonstrate the industrial-scale implementation of coal-gasification for the production of electricity and hydrogen, with a provision for carbon sequestration. Separation technology to efficiently remove the hydrogen gas is vital to improve process performance and enable the sequestration of the carbon dioxide by-product. However, no separation technology curren ...

New neutron radiographic imaging facilities at the Spallation Neutron Source will require detectors with better position resolution and rate capability than available with existing technologies. This project will develop a novel type of compact thermal neutron collimator for these detectors. These compact collimators can be employed to effectively reduce post scattered neutrons arriving at the d ...

Hyperspectral Imaging ,HIS, provides a means for detecting weapons of mass destruction. A core element of a HSI system is a tunable wavelength filter. There is a need for faster tunable wavelength filters than those that currently exist in practice. To address this need, this project will develop a tunable wavelength filter based on a holgraphically-formed, polymer-dispersed liquid crystal, HPD ...

The value of traded financial instruments used to comply with greenhouse gas emissions reached 29 billion dollars in 2006, yet pricing for carbon credits has remained volatile and uncertain, in part due to an incomplete understanding of the carbon cycle at local, regional, and global scales. Monitoring CO2 concentrations is critical to quantifying carbon fluxes e.g., sequestration per sink; deseq ...

Organic Light Emitting Diodes ,OLEDs, currently suffer from materials stability and shortened device lifetimes when driven to the levels required for general illumination. Although much progress has been made to extend the life of these devices, their lifetimes are still not adequate when driven to the 850 candel per meter squared required for illumination. Many of the problems stem from the cho ...

Many DOE applications are becoming more data intensive, and petascale computing systems are being developed to respond to this need. As these larger computing machines are developed, it is crucial that their file systems do not become the primary bottleneck. In order to meet the demand of such systems, the metadata server must be parallelized, and hardware offload techniques must be utilized to ...

In response to the DOE request for multiple-use photovoltaic applications, this project will develop technology for the Next Generation Solar Powered Monorail. In particular, the project will implement an innovative approach for integrating statewide transportation, renewable energy, and regenerative braking. Specifically, a 1/6-scale monorail model will be modeled to accommodate a wireless sys ...
