ALTHOUGH THE USE OF CERAMIC COMPOSITES IN AEROSPACE SYSTEMS IS MONOTONICALLY INCREASING, THERE ARE NOT MANY ANALYTICAL AND EXPERIMENTAL STUDIES REVEALING THE UNIQUE CHARACTERISTICS THESE MATERIALS CAN PROVIDE. IT IS BELIEVED THAT THESE MATERIALS HAVE GREAT PROMISE FOR HIGH TEMPERATURE STRUCTURAL APPLICATIONS INCLUDING HOT TURBINE ENGINE COMPONENTS. WHILE FEW FIBER REINFORCED CERAMIC SYSTEMS ARE CO ...

EMISSION OF SULFUR OXIDES (SOX) AND NITROGEN OXIDES (NOX) IN FLUE GASES IS A MAJOR CAUSE OF AIR POLLUTION AND ACID RAIN. CURRENT TECHNOLOGIES FOR SOX REMOVAL ARE EXPENSIVE AND CUMBERSOME. SULFUR DIOXIDE IS CONVERTED TO SULFURIC ACID, WHICH IS VERY CORROSIVE AND DIFFICULT TO STORE AND TRANSPORT. REMOVAL OF NOX IS ACCOMPLISHED BY CATALYTIC CONVERSION USING PLATINUM CATALYSTS. PLATINUM CATALYSTS ARE ...

A SMALLER, LIGHTER, MORE EFFICIENT, AND MORE RELIABLE CLINICAL GAS ANALYZER FOR RESPIRATORY AND ANESTHETIC GAS MONITORING IS NEEDED. EXISTING LASER RAMAN-BASED INSTRUMENTATION USES A LARGE, HEAVY, AND EXTREMELY INEFFICIENT (0.1 PERCENT) ARGON ION LASER WITH AN INTRACAVITY GAS CELL. THE LONG-TERM OBJECTIVE OF THIS STUDYIS TO IMPLEMENT A SOLID-STATE ALTERNATIVE TO THE EXISTING ION LASER. SUCH A LASE ...

REAL TIME ON-LINE ANALYSIS OF STACK GASSES IS NECESSARY TO MONITOR EFFLUENTS AND TO PERMIT FEEDBACK CONTROL OF COMBUSTION PROCESS AND DOWN STREAM SCRUBBER SYSTEMS. MULTIMEDIA POLLUTION ANALYSIS REQUIRES MULTIPLE SENSOR TECHNOLOGY WITH PRESENT COMMERCIALLY AVAILABLE INSTRUMENTATION. CURRENTLY, COMPLEX ANALYTICAL SYSTEMS MUSTBE ASSEMBLED THAT ARE EXPENSIVE, PRONE TO DRIFT, AND DIFFICULT TO OPERATE A ...

THE ACCEPTANCE OF EXTRACORPOREAL OXYGENATION DEVICES BASED ON GAS TRANSFER THROUGH A MEMBRANE WILL DEPEND TO A LARGE EXTENT ON THE AVAILABILITY OF SIMPLER, EASIER TO USE, SAFER,AND LOWERCOST DEVICES. OXYGENATORS USING MICROPOROUS HOLLOWFIBERS HAVE COME INTO WIDER USE THE LAST FIVE YEARS. THEY PRESENT MORE MEMBRANE SURFACE TO BLOOD AND GAS PHASES FOR EQUIVALENT VOLUME AND DO NOT REQUIRE A SUPPLEMEN ...

CLASSICAL ASSAYS FOR DETERMINING BLOOD AND URINE GLUCOSE HAVE LIMITED VALUE FOR THE MONITORING OF AN INDIVIDUAL'S BLOOD GLUCOSE LEVEL OVER TIME. MEASUREMENT OF GLYCATED HEMOGLOBIN (GHB) IS ALREADY GAINING ACCEPTANCE FOR MANAGEMENT OF PERSONS WITH DIABETES MELLITUS. GHB LEVELS ARE NOT ONLY USEFUL FOR DIAGNOSIS BUT ALSO FOR THE ESTABLISHMENT OF CARE GOALS AND FOR CARE REINFORCEMENT. IN THE FUTURE, M ...

THIS PROGRAM IS RELATED TO THE DEVELOPMENT OF A PLATINUM-POLYSTYRENE ELECTRODE WITH TEXTURED SURFACE FOR A SUBCUTANEOUS ELECTROCATALYTIC SENSOR. THE SUBCUTANEOUS SENSOR HAS LOWER RISKS COMPARED TO AN INTRAVENOUS SENSOR, SOIT IS CONSIDERED FOR LONG-TERM MONITORING PURPOSES. IT HAS BEEN DEMONSTRATED THAT TEXTURED SURFACES ARE FAVORABLE FOR IMPLANTATION TO THE SOFT TISSUE DUE TO BETTER VASCULARIZATIO ...

REQUIREMENTS FOR RAILGUN ARMATURES DICTATE MATERIALS PROPERTIES VALUESWHICH ARE DIFFICULT TO OBTAIN FROM CONVENTIONAL MATERIALS. THE NEED EXISTS FOR A MATERIAL WHICH HAS LOW DENSITY, HIGH MELTING POINT, HIGH THERMAL CONDUCTIVITY, LOW COEFFICIENT OF THERMAL EXPANSION, HIGH ELECTRICAL CONDUCTIVITY, HIGH VALUES FOR STRENGTH, AND GOOD CHARACTERISTICS OF LUBRICITY. GRAPHITE FIBER GROWN FROM PYROLYSIS O ...

THE ECONOMICS OF LAUNCH COST, COUPLED WITH POWER REQUIREMENTS FOR SPACE BASED WEAPONS SYSTEMS, MANDATE OPTIMIZATION OF THE RATIO OF POWER TO MASS IN SPACE POWER SYSTEMS. A LOW DENSITY, HIGH TEMPERATURE, RADIATION-COMPATIBLE MATERIAL WITH HIGH THERMAL CONDUCTIVITY USED FOR CONSTRUCTION OF THERMAL MANAGEMENT DEVICES WOULD OFFER A SUBSTANTIAL ENHANCEMENT TO THE POWER/MASS RATIO, AND TO THE COST OF DE ...
