CERAMATEC HAS CONDUCTED EXPLORATORY RESEARCH AND DEVELOPMENT ON MONOLITHIC AND COMPOSITE MATERIALS IN THE ZRB2 AND TIB2 SYSTEMS AND HAS OBTAINED VERY ENCOURAGING RESULTS WITH SEVERAL PROPRIETARY COMPOSITIONS/CONSTRUCTIONS. THE AVERAGE STRENGTH OF A BASELINE TIB2 COMPOSITION WAS MEASURED AT 877 MPA (127.3 KSI). COMPOSITE STRUCTURESWITH DISCONTINUOUS REINFORCEMENT HAD STRENGTHS IN THE RANGE 400-600 ...

THE OVERALL OBJECTIVE OF THIS PROJECT IS TO DEMONSTRATE THE SUCCESSFUL FABRICATION AND DENSIFICATION OF CERAMIC MATRIX COMPOSITES FORMED BY INJECTION MOLDING. TO ACCOMPLISH THIS OBJECTIVE, A DESIGNED TEST MATRIX WILL BE DEVELOPED THAT WILL SYSTEMATICALLY INVESTIGATE THE KEY INJECTION MOLDING AND DEBINDING PARAMETERS SUCH AS BINDER COMPOSITION, SOLIDS RATIO, MOLDING CONDITIONS, DEBINDING CONDITIONS ...

IT IS DESIRABLE TO HAVE A MTHOD FOR EFFICIENT, COST EFFEC- TIVE, AND SIMULTANEOUS REMOVAL OF PB(II), AG(I), CD(II) AND HG(II) FROM POTABLE WATER TO LEVELS WELL BELOW THEIR EPA LIMITS. SUCH A METHOD COULD BE USED BY BOTH MUNICIPAL WATER WASTE TREATMENT PLALNTS. THE INTERACTION OF THE MACROCYCLE TETRAAZA-18CROWN WITH THE METALS OF INTEREST IS OF SUFFI- CIENT STRENGTH AND SELECTIVITY TO REMOVE THE ME ...

UTAH CONTAINS SIGNIFICANT RESOURCES OF TAR SANDS WHICH, IF DEVELOPED, COULD BECOME AN IMPORTANT COMPONENT OF THE NATION'S REQUIREMENTS FOR PETROLEUM PRODUCTS. THE ECONOMICSFOR PRODUCTION OF SYNCRUDE FROM UTAH TAR SANDS HAVE HISTORICALLY BEEN JUST BEYOND THE RANGE OF PROFITABILITY. PRODUCTION OF ASPHALT, HOWEVER, APPEARS TO BE PROFITABLE TODAY. CAPITAL AND OPERATING COSTS FOR PRODUCTION OF ASPHALT ...

THE APPLICATION OF PHYSICAL-CHEMICAL PRINCIPLES TO BIOLOGICAL SYSTEMS FREQUENTLY LEADS TO SITUATIONS IN WHICH THE QUANTITATIVE TREATMENT OF CONCEPTUALLY SIMPLE MODELS IS CONFOUNDED BY THE COMPLEXITY OF THE SYSTEM. SUCH IS THE CASE, FOR EXAMPLE, IN THE STUDY OF THE PERMEATION (AND POSSIBLE CONCURRENT METABOLISM) OF DRUGS THROUGH COMPLEX BIOLOGICAL MEMBRANES, THE PHYSIOLOGICAL MODELING OF THE DISTRI ...

THE LACK OF EFFICIENT TOOLS TO IDENTIFY GENOTYPES OF SUPERIOR WATER-USE EFFICIENCY (WUE) HAS LED TO LITTLE PRACTICAL SUCCESS IN IMPROVING CROPS WITH REGARD TO THIS VERY IMPORTANT TRAIT. HOWEVER, STABLE CARBON ISOTOPE ( (13)C) ANALYSIS IS PRESENTLY EMERGING AS A POTENTIALLY HIGHLY EFFICIENT MEANS OF EVALUATING PLANTS FOR WUE, ALTHOUGH THE TECHNOLOGY HAS NOT YET BEEN APPLIED TO CROP DEVELOPMENT. IN ...

TECHNICAL RESEARCH ASSOCIATES, INC. PROPOSES THE DEVELOPMENTOF A NOVEL PLATELET-HARVESTING SYSTEM BASED ON A PREVIOUSLY DEVELOPED ULTRASOUND SEPARATION TECHNOLOGY. THIS TECHNOLOGY, DEVELOPED UNDER AN NHLBI GRANT, ALLOWS THE SEQUENTIAL SEPARATION OF CELLS BASED ON THEIR SIZE, EVEN THOSE CELLS THAT HAVE IDENTICAL DENSITIES. FIRST, RESIDUAL ERYTHROCYTES AND LARGE LEUKOCYTES CAN BE SEPARATED FROM PLAT ...

IN ORDER TO USE THE NEW CERAMIC SUPERCONDUCTOR MATERIALS IN MANY APPLICATIONS, THE NORMALLY BRITTLE MATERIALS MUST BE FORMED INTO WIRES. THIS PROPOSAL SUGGESTS A WET CHEMISTRY TECHNIQUE FOR FORMING THE SUPERCONDUCTOR COMPOUND INTO A WIRE, WHICH WILL THEN BE COATED WITH A METAL JACKET TO PROTECT THE WIRE FORM PHYSICAL ABUSE AND ENVIRONMENTAL DEGRADATION. BECAUSE THE COATING PROCESS WILL BE ESSENTIA ...

THE LONG-TERM OBJECTIVE OF THIS PROJECT IS TO DEVELOP A PROTOTYPE SCANNING SYSTEM FROM WHICH NOVEL AND ADVANCED ULTRASOUND SCANNING SYSTEMS CAN BE MANUFACTURED FOR THE IMAGING, TISSUE CHARACTERIZATION, AND DIAGNOSIS OF CANCER AND OTHER DISEASES. IT WILL GIVE SUPERIOR IMAGES OF OBSTETRICAL CONDITIONS, VASCULAR DISEASE, LIVER DISEASE, ANDOTHER ABDOMINAL CONDITIONS. THIS ADVANCED SYSTEM IS BASED ON E ...

CURRENT METHODS USED TO MEASURE STRAIN AT HIGH TEMPERATURES DEPEND ON UNDESIRABLE ATTACHMENTS, EXTENSIONS, OR INDENTATIONS OF THE TEST SAMPLES. THIS STUDY WILL INVESTIGATE THE USE OF NEW TECHNOLOGY TO APPLY HIGH TEMPERATURE COATING MARKS TO TEST SAMPLES. THESE APPLIED MARKS WILL ACT AS A REFERENCE OR GAUGE FOR OPTICAL STRAIN MEASUREMENT. MATERIALS INCLUDING REFRACTORY METALS AND CERAMICS WILL BE A ...
