COALITION TECHNOLOGIES, LTD., (CTL) RESEARCH HAD IMPROVED A SIMPLE GAS PHASE TREATMENT (SULFONATION) OF WASTE RUBBER AND PLASTICS. RESULTS FROM LABORATORY SCALE EXPERIMENTS DONE AT MICHIGAN STATE UNIVERSITY HAVE SHOWN THAT CONCRETE MADE FROM SULFONATED RUBBER AND PLASTIC PROVIDED BY CTL HAS IMPROVED IMPACT RESISTANCE AS MEASURED BY ASTM STANDARD TESTS. IN MANY CASES, WASTE PLASTICS AND RUBBER ARE ...

CYGNUS LASER PROPOSES A REVOLUTIONARY METHOD OF DYNAMICALLY CONTROLLING THE HARMONIC GENERATION PROCESS. PRESENT HARMONIC GENREATION TECHNOLOGY INVOLVES DETERMINING AN OPTIMUM CRYSTAL SIZE AND LENGTH FOR A GIVEN FUNDAMENTAL LASER, THEN USING THE CRYSTAL AS A PASSIVE ELEMENT. THE ONLY AVAILABLE CONTROL MECHANISMS ARE QUITE OFTEN MECHANICAL ALIGNMENT AND TEMPERATURE CONTROL. THE CRYSTAL ACTS AS A NO ...

AT CYGNUS LASER, WE HAVE BECOME CONVINCED THAT NONLINEAR OPTICAL MATERIALS WITH DESIRABLE PROPERTIES FOR HARMONIC GENERATION AND FREQUENCY CONVERSION ALREADY EXIST. IN PARTICULAR, WE HAVE ALREADY DEMONSTRATED A KTP SECOND HARMONIC GENERATOR FOR 1064 NM LASERS IN OUR LABORATORY WITH A CONVERSION EFFICIENCY OF 80%. WE UNDERSTAND IN DETAIL THE PHYSICS OF SECOND HARMONIC GENERATION WELL BEYOND THE SIM ...

MANY OF THE COMMERCIAL SENSORS IN USE (OR UNDER DEVELOPMENT) ARE BASED IN METAL-OXIDE CERAMIC MATERIALS. METAL-OXIDES OFFER SPECIAL ADVANTAGES BECAUSE OF THEIR CHEMICAL AND THERMAL STABILITY, FAST RESPONSE TIMES, AND SENSITIVITY TO ELECTROCHEMICAL CHANGES. THERE ARE REPORTED CASES THAT SHOW ADSORPTION OF WATER IN METAL OXIDES OFTEN ENHANCING BOTH THE SURFACE CONDUCTIVITY AND DIELECTRIC PROPERTIES ...

THE OBJECTIVE OF THIS PROPOSAL IS TO DEVELOP A 1-PICOSECOND MONOLITHICALLY INTEGRATABLE PHOTODETECTOR WITH 0.2 A/W RESPONSIVITY FOR ULTIMATE USE AT 1600 NM. THE DETECTOR WILL RELY ON THE INTRISIC CARRIER LIFETIME OF THE SEMICONDUCTOR FOR ITS SPEED AND ON SUBMICROMETER-SPACED INTERDIGITATED FINGER ELECTRODES FOR ITS SENSITIVITY. ONE SEMICONDUCTOR ALREADY DEVELOPED FOR SHORTER WAVELENGTH APPLICATION ...

AN IMPORTANT COMPONENT OF ARCJET THRUSTERS IS THE INSULATOR HOLDING THE CATHODE BASE AND SEPARATING THE ELECTRODES. THE CURRENT BASELINE MATERIAL IS BORON NITRIDE (BN), WHICH IS WELL KNOWN FOR ITS HIGH ELECTRICAL RESISTIVITY AND HIGH THERMAL CONDUCTIVITY. HOWEVER, AT ARCJET OPERATING TEMPERATURE, BN HAS A DRAMATIC INCREASE IN ELECTRICAL CONDUCTIVITY AND A DECREASE IN THERMAL CONDUCTIVITY. ADDITION ...

LEAD IN SOIL MUST BE TREATED IN ORDER TO REDUCE THE EXPOSURE RISK ASSOCIATED WITH LEAD MIGRATION AND LEAD BIOAVAILABILITY. SINCE THE LEVEL OF LEAD IN CONTAMINATED SOIL IS USUALLY VERY LOW, A COST-EFFECTIVE AND SAFE LEAD FIXATION TECHNOLOGY IS NEEDED. THIS RESEARCH WILL INVESTIGATE A NOVEL LEAD FIXATION TECHNOLOGY BASED ON NATURAL SOIL CHEMICAL REACTIONS WITH ENVIRONMENTALLY SAFE MATERIALS. PHASE I ...
