79579 Because of stringent environmental regulations, the power generation industry must take measures to reduce the emission of NOx and SOx. Low-NOx burners reduce emissions by changing the combustion characteristic of coal boilers, but they increase the amount of residual unburned carbon in the fly ash. Increased carbon levels in fly ash make air-entrained concrete production more difficult , ...

78103 The DOE-funded Transmission Electron Aberration-corrected Microscope (TEAM) development project seeks to achieve the imaging and analysis of individual nanostructures at atomic resolution in three dimensions (3D). Although atomic resolution tomography has been the preferred approach, an alternative approach, atom probe field ion microscopy (APFIM), has been explored for the past decade or s ...

797870 In the fast ignition concept for inertial fusion energy, high-intensity short-pulse lasers are used to create energetic particles (protons and relativistic electrons) that propagate to the fuel within a compressed capsule. The efficient transport of these energetic particles to the fuel is a key issue in fast ignition research. A combination of well-diagnosed experiments and well-tested s ...

79082S High order modes in radio-frequency accelerating cavities typically degrade the performance of high-energy colliders, and consequently a significant effort is put into eliminating or strongly damping these modes. Photon band gap structures are a novel and promising approach to this problem, and integrated analysis tools that can draw on parallel computing resources are needed to accelerat ...

78140S Strong radio-frequency electric fields in high-power components used in colliders can induce a resonant cascade of particles near internal surfaces (called multipacting) that can lead to surface breakdown and device failure, in some cases limiting the power than can be handled to a fraction of the design specification. Existing tools available to analyze this phenomenon have limited accu ...

Extensive research (Ukraine) has shown that high strength continuous fibers of basalt can be produced. These fibers are inexpensive and have exceptionally high strength, stiffness and corrosion resistance. Basalt is a naturally occurring volcanic mineral, consisting a variety concentration of oxides. The product envisioned is a low-cost, corrosion resistant replacement for steel bar in reinforc ...

THERE ARE MANY IDEAS ON WAYS TO UTILIZE BIOMASS MATERIALS. THEY CAN BE CONVERTED INTO A FIBER THAT CAN BE ACETYLATED TOBE USED FOR THE PRODUCTION OF COMPOSITES. THESE COMPOSITES CAN BE USED IN MANY STRUCTURAL AND NONSTRUCTURAL APPLICATIONS. BY UTILIZING THE XYLAN-I U.S. PATENT # 4,842,877, THE THREE-DIMENSIONAL BIOMASS CHANGES ITS LIGNIN-CELLULOSE-HEMICELLULOSE CONFIGURATION TO ONE WHICH ALLOWS FO ...
