THE AVAILABILITY OF HIGH INTENSITY, SYNCHROTRON SOURCES TO PRODUCE HIGH FLUX, MONOCHROMATIC X-RAY BEAMS HAS RESULTEDIN IMPORTANT ADVANCES IN THE STUDY AND DETERMINATION OF THE STRUCTURE OF LARGE, FRAGILE BIOLOGICAL MACROMOLECULES. ALTHOUGH THESE SOURCES REPRESENT A MAJOR ADVANCE IN TECHNOLOGY, AT PRESENT THERE ARE NO LARGE AREA DETECTORS WITH BOTH THE HIGH FLUX CAPABILITY AND GOOD SPATIAL RESOLUTI ...

THIS RESEARCH PROGRAM WILL DEMONSTRATE THE TECHNICAL AND ECONOMIC FEASIBILITY OF THE PROPOSED MAGNETIC SEPARATOR ON PULVERIZED COAL. A THEORETICAL COMPARISON OF THE PROPOSED SEPARATOR WITH WORK PUBLISHED ON OPEN GRADIENT MAGNETIC SEPARATION BY THE OAK RIDGE NATIONAL LABORATORY INDICATES THAT THE SEPARATOR WILL HAVE HIGH LEVELS OF ASH CLEANING. THIS IS BECAUSE OF ITS COUNTERCURRENT PRINCIPLE OF OPE ...

INNOVATIVE AND PRACTICAL MATERIALS ARE DESCRIBED WHICH UNDERGO REVERSIBLE SOLID-STATE ENERGY STORAGE TRANSITIONS. THIS TECHNOLOGY WILL COMBINE THE PROPERTIES OF HIGH LATENT HEAT STORAGE CAPACITY AND EXCELLENT THERMAL CONDUCTIVITY TO YIELD MATERIALS WHICH CAN QUICKLY RESPOND TO THE IMPOSITION OF THERMAL STRESS, EITHER HOT OR COLD.

DUE TO THE HIGH COST OF TRANSPORTATION AND HIGH SULFUR ASH CONTENT, SOLID COAL IS SUITABLE FOR USE ONLY IN SPECIALLY EQUIPPED POWER GENERATION FACILITIES. DIRECT COAL LIQUEFACTION IS AN ATTRACTIVE TECHNOLOGY FOLLOWED BY THE DOEBUT CURRENTLY USES EXPENSIVE MOLYBDENUM CATALYST. IRON IS RELATIVELY INEXPENSIVE AND ITS USE WOULD ELIMINATE A COSTLY STEP OF CATALYST RECOVERY. CONSIDERABLE RESEARCH HAS SH ...

ALTHOUGH INCREASED UTILIZATION OF AMERICAN COAL RESERVES REMAINS A PRIORITY FOR DOE, THE SULFUR CONTENT OF COAL GASESIS INCOMPATIBLE WITH MANY INTENDED USES, SUCH AS INTEGRATED GASIFICATION COMBINED-CYCLE (IGCC) SYSTEMS, FUEL CELL POWERPLANTS, AND AS A FEEDSTOCK IN THE CHEMICAL PROCESS INDUSTRY; IN ADDITION, SULFUR-CONTAINING EMISSIONS ARE ENVIRONMENTALLY OBJECTIONABLE. THE MOST DEVELOPED DESULFUR ...
