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 ...

Ultrasupercritical (USC) steam boilers will operate at higher temperature/pressure than subcritical and supercritical steam boilers in service today. However, the majority of current high-temperature materials do not posses the desired characteristics for the operating conditions of a USC unit (760 C/35MPa). This project will develop innovative composite powders and composites that will surpass th ...

Scientists have proposed reducing greenhouse gas emissions by capturing combustion gases from power plants and injecting the carbon dioxide into geologic subsurface structures, where it would remain sequestered for geological periods of time. Demonstration projects are being funded by DOE to assess the storage capacity of sequestration reservoirs. Sophisticated monitoring tools are essential to ...

Electrical contacts are a critical part of photovoltaic technology. For these contacts, there is an increasing drive to develop improved processes that differ from current approaches based on physical vapor deposition (PVD) and photolithography. In particular, it would be desirable to develop solution-based atmospheric processes, which would be more cost effective, environmentally benign, and mate ...

DOE¿s FutureGen Initiative involves the development and demonstration of fuel-flexible gas turbine combustors that burn fuels with high hydrogen concentrations (e.g. syngas or pure hydrogen). Combustion goals include high efficiency and low emissions (NOx < 2 ppmv). Advanced Large Eddy Simulation (LES) analysis is expected to play an important role in developing fuel-flexible combustion technolog ...

Cellulose is a highly sustainable global resource with considerable relevance to bio-ethanol production. Lignocellulose is a naturally occurring complex of plant-derived materials that includes the hydrophilic sugar polymers cellulose and hemicellulose, and the hydrophobic organic polymer lignin. Although lignocellulose is one of the most abundant and widespread bioenergy feedstocks available on E ...

Traditional knowledge sources, such as thesauri and subject headings lists, are helpful for manual use, but the format of the encoded semantic information and the prevalent indexing and search tools are not well suited for Web retrieval applications. Classic examples of such knowledge sources are the ETDE/INIS Joint Thesaurus for energy information, the Library of Congress Subject Headings, and th ...

Traditional thesauri typically have entries with semantic relationships that are helpful for manual use, but the format of the semantic information is usually not conducive to their incorporation in Web retrieval applications. In addition, the number of thesaurus entries and relationships are limited, compared to the much larger and richer concept space of the scientific domain that a given thesau ...

The effective acquisition and sharing of knowledge across the World Wide Web remains a formidable challenge for today¿s Internet user. Exacerbating this challenge is the need to integrate information across a wide array of disparate data types, ranging from textual documents, to 2D and 3D imagery, to geospatial data layers, to numerical datasets, and so on. Consequently, there is a pressing need ...

The Neutrinoless Double Beta Decay Underground Detector has been identified by DOE as a high scientific priority. Unfortunately, the current generation of proposed experiments to determine neutrino mass would require 500 kg of germanium (Ge) that is isotopically enriched to 86% in 76Ge. The cost of this specialized Ge would exceed $100 million. 150Nd is an alternate parent isotope for neutrinoless ...
