REMOVAL OF TOXIC METALS FROM WASTEWATER STREAMS HAS BECOME A PROBLEM OF INCREASING NATIONAL IMPORTANCE, AS A RESULT OF INCREASING CONCERN FOR OUR ENVIRONMENT, AND INCREASINGLY STRINGENT WASTE DISPOSAL REGULATIONS. CHROMATOCHEM, INC., HAS DEVELOPED AN ECONOMICAL AND EFFECTIVE NEW TECHNOLOGY FOR THE REMOVAL OF LOW LEVELS OF TOXIC METAL IONS FROM WASTEWATER STREAMS, USING SOLID PHASE EXTRACTION (SPE) ...

THE NEED FOR SMALLER SEMICONDUCTOR DEVICE STRUCTURES FOR USE IN VERY HIGH SPEED MICROELECTRONICS REQUIRES A NEW GENERATION OF PLASMA ETCHING TECHNOLOGY. ECR PROMISES TO PROVIDE FEATURES AS SMALL AS 0.2 MICRONS IN SIZE, AS WELL AS A HIGH DEGREE OF ETCHING ANISOTROPY, SELECTIVITY, ETCH RATES, AND LOW DAMAGE. FOR MANUFACTURING PROCESS CONTROL INVOLVING ECR ETCHING IN PRODUCTION OF ELECTRONICS AND OPT ...

II-VI SEMICONDUCTORS, ESPECIALLY HGCDTE, ARE USED EXTENSIVELY IN INFRARED IMAGING AND NIGHT VISION ELECTRONICS. THESE SEMICONDUCTORS HAVE SOFT SURFACES; GROWTH OF DEVICE QUALITY MATERIAL IS DIFFICULT; DEVICE YIELDS ARE LOW, AND COSTS ARE HIGH. THERE IS THUS A GREAT NEED FOR NON-INVASIVE PROCESS CONTROL. RECENTLY OUR COMPANY HAS DEVELOPED IN SITU SPECTROSCOPIC ELLIPSOMETRY FOR THE MONITOR OF AL(X)G ...

ENZYMES OF INTEREST IN CHEMICAL/BIOLOGICAL DEFENSE, PARTICULALY OXIDASES AND PEROXIDASES, WOULD BE MORE USEFUL IF THEY COULD WITHSTAND HIGH TEMPERATURES AND HAD A LONGER SHELF LIFE. THERMALLY LABILE FORMS NOW AVAILABLE COULD BE SYNTHETICALLY STABILIZED BUT THIS WOULD BE EXPENSIVE. MICROORGANISMS EXISTING IN HIGH TEMPERATURE HABITATS SURVIVE SUCH CONDITIONS BECAUSE THEY PRODUCE HEAT STABLE ENZYMES. ...

THE U.S. POSSESSES HUGE COAL RESERVES, BUT SULFUR DIOXIDE (SO2) RELEASED UPON COMBUSTION IS A MAJOR CONTRIBUTOR TO ACID RAIN. SIGNIFICANT ADVANCES HAVE BEEN MADE IN THE DEVELOPMENT OF MICROBIAL PROCESSES FOR PRECOMBUSTION REMOVALOF INORGANIC SULFUR FROM COAL. THIOBACILLUS AND SULFOLOBUS SP. HAVE BEEN MOST FREQUENTLY EMPLOYED. THEY ARE OPTIMALLY ADAPTED TO FUNCTION AT A PH BELOW 3 AND OFTEN AT ELEV ...

SCATTER FROM GROUND-BASED LASER PORTS (WEAPONS, COMMUNICATION SYSTEMS, RANGE FINDERS) CAN BE LARGE ENOUGH THAT THE LASER LOCATION MAY BE DETERMINED BY DETECTORS POSITIONED WELL AWAY FROM THE BEAM. PORT SCATTER CAN BE REDUCED, BUT NOT ELIMINATED, THROUGH THE USE OF BAFFLES TO LIMIT DIRECT VIEWING OF THE LASER OPTICS. THIS DOCUMENT PROPOSES DEVELOPING A METHOD TO PREDICT THE SCATTER SIGNAL FROM LASE ...
