RESEARCH ON SEPARATION AND RECOVERY OF ACTIVATED CARBON FROMFLYASH, TOGETHER WITH RECOVERY OF AN ASTM-APPROVED CEMENT SUBSTITUTE USING ADVANCED ENERGY DYNAMICS' STATE-OF-THE-ART ELECTROSTATIC SEPARATION PROCESS IS PROPOSED. THIS PROCESS USES THE DIFFERENCES IN WORK FUNCTIONS OF PARTICLES OF DIVERSE COMPOSITION TO EFFECT A SEPARATION OF PROCESSED MATERIAL. IT HAS THE POTENTIAL OF TRANSFORMING FLYAS ...

A CONSTITUTIVE MODEL FOR PREDICTING THE EFFECTS OF THE MANUFACTURING PROCESS ON THE MECHANICAL PROPERTIES OF ENGINEERING POLYMERS WILL BE DEVELOPED. THE CONSTITUTIVE MODEL, WHICH HAS NO ADJUSTABLE CONSTANTS, WILL PREDICT (1) THE NON-NEWTONIAN FLOW OF POLYMER FLUIDS; (2) THE SOLIDIFICATION PROCESS DURING COOLING FROM THE FLUID INTO THE GLASS; AND (3) THE THREE-DIMENSIONAL STRESS-STRAIN BEHAVIOR, IN ...

CLEAN SOURCES OF ATOMIC CHLORINE ARE REQUIRED FOR MECHANISTIC STUDIES OF SEMICONDUCTOR ETCHING PROCESSES. IN THIS PROPOSAL, AERODYNE RESEARCH, INC. DESCRIBES MODIFICATIONS TO AN EXISTING ULTRAHIGH VACUUM COMPATIBLE, EFFUSIVE BEAM, MICROWAVE DISCHARGE FLUORINE ATOM SOURCE WHICH WOULD ALLOW ITS USE AS A SOURCE OF CHLORINE ATOMS, AND THEY DEFINE MEASUREMENTS TO CHARACTERIZE AND DEMONSTRATE ITS OPERAT ...

THE PURPOSE OF THE PROPOSED STUDY IS THE DEVELOPMENT OF INSTRUMENTATION TO MEASURE FLUXES OF ATMOSPHERIC TRACE GASES TO OR FROM THE EARTH'S SURFACE. THE METHOD WE PROPOSEIS BASED ON THE WELL ESTABLISHED EDDY CORRELATION TECHNIQUE AND WOULD USE A TUNABLE DIODE LASER LIGHT SOURCE COMBINED WITH A MULTIPLE PASS ABSORPTION CELL TO DETECT TRACE SPECIES AT SUB-PART-PER-BILLION LEVELS. THE PROPOSED INSTRU ...

THALLIUM BROMIDE (T1BR) IS A NEW CUBIC SEMICONDUCTOR. THE HIGH ATOMIC NUMBERS OF ITS CONSTITUENT ELEMENTS GIVES IT EXTRAORDINARY PHOTOELECTRIC ABSORPTION EFFICIENCY FOR GAMMA PHOTONS, WHILE ITS 2.5 EV BANDGAP PROMISES PERFORMANCE AT TEMPERATURES UP TO 250XC. IT HAS SHOWN SOME PROMISE AS AHIGH EFFICIENCY SOLID-STATE DETECTOR, BUT EARLY DEVICES WERELIMITED BY MATERIAL IMPURITIES AND IMPERFECTIONS. I ...

NUCLEAR RADIATION SENSORS ARE USED IN MANY IMPORTANT APPLICATIONS IN RESEARCH AND INDUSTRY. GOOD ENERGY RESOLUTION IS A VITAL PROPERTY OF NUCLEAR RADIATION SPECTROMETERS. THE BEST CONTEMPORARY COMMERCIAL UNITS CAN DISCRIMINATE DIFFERENCES ABOUT 100 EV. BETTER PERFORMANCE HAS BECOME AVAILABLE THROUGH THE APPLICATION OF LOW TC SUPERCONDUCTORS WHICH HAVE ATTAINED RESOLUTION OF TENS OF EV. SUCH DEVICE ...

THE PULTRUSION PROCESS IS ONE OF THE LEAST EXPENSIVE METHODSFOR PRODUCING STRUCTURAL COMPONENTS FROM ADVANCED COMPOSITE MATERIALS. THE PROCESS HAS TRADITIONALLY SUFFERED FROM THE INABILITY TO PRODUCE PARTS OF REPEATEDLY CONSISTENT QUALITY. AMERICAN COMPOSITE TECHNOLOGY (ACT) HAS BEEN ACTIVELY INVESTIGATING METHODS FOR INCREASING THE CONSISTENCY OF PULTRUDED COMPOSITES. THEY FEEL THAT MAJOR QUALITY ...

ANALYTIC POWER PROPOSES THE DEVELOPMENT OF AN ELECTROPNEUMATIC ACTUATOR WHICH PERMITS SWIFT, SMOOTH, ELECTRONICALLY CONTROLLED MOVEMENT, EVEN UNDER HEAVY LOADS. THE APPROACH IS AN EXTENSION OF THEIR ELECTROCHEMICAL REFRIGERATION COMPRESSOR TECHNOLOGY WHICH HAS BEEN SUPPORTEDBY PRIVATE INDUSTRY AND AN AIR FORCE SBIR PROGRAM. THEIR ENGINEERING RESEARCH PROGRAM WILL DEMONSTRATE THE KEY ELEMENTS OF ME ...
