AN INNOVATIVE ALTERNATIVE TO CONVENTIONAL APPROACHES TOWARD CHLOROFLUOROCARBON AND HALON DESTRUCTION (SUCH AS OXIDATIVE THERMAL PROCESSES) IS BASED ON APPLICATION OF THE TECHNOLOGY OF RADIOFREQUENCY (RF) GLOW DISCHARGE PLASMA TREATMENTS OF ORGANIC MATERIALS TO CFCS AND HALONS. IN ORDER TO EXPAND ON SOME VERY SLIGHT PRECEDENCE FOR RF PLASMA POLYMERIZATION OF CFCS, RESEARCHERS ARE DEMONSTRATING THE ...

THE COMBINATION OF GAS CHROMATOGRAPHY WITH MASS SPECTROMETRY(GC/MS) PROVIDES THE BEST GENERAL PURPOSE ANALYTICAL INSTRUMENT FOR SENSITIVE CHARACTERIZATION OF COMPLEX MIXTURES. IT IS USED IN THE FIELDS OF CHEMISTRY, BIOLOGY, GEOCHEMISTRY, ENVIRONMENTAL SCIENCE AND FORENSICS. IN MOST CASES, THE GAS CHROMATOGRAPH SEPARATES THE STARTING MIXTURE INTO ITS CONSTITUENT COMPOUNDS PRIOR TO ANALYSIS BY THE M ...

THE HYDROXYL RADICAL (OH) PLAYS A KEY ROLE IN THE PHOTOCHEMISTRY OF BOTH THE TROPOSPHERE AND THE STRATOSPHERE. IT IS THE PRIMARY OXIDIZING AGENT RESPONSIBLE FOR THE REMOVAL OF MOST TRACE GASES INCLUDING CO AND CH4. SINCE THE OH RADICAL DETERMINES THE LIFETIMES AND, THUS, THE CONCENTRATIONS OF MANY CHEMICAL SPECIES, ACCURATE DETERMINATION OF OH CONCENTRATION IS PIVOTAL IN UNDERSTANDING ATMOSPHERI ...

ULTRAFAST LASERS (LASERS THAT GENERATE PULSES WITH DURATIONS OF ~10 PICOSECONDS OR LESS) HAVE A LARGE NUMBER OF APPLICATIONS IN BIOCHEMISTRY, CHEMISTRY, PHYSICS, AND ELECTRICAL ENGINEERING. UNFORTUNATELY, THESE SYSTEMS ARE DIFFICULT TO USE LARGELY BECAUSE ULTRAFAST LASER PULSES ARE EXTREMELY DIFFICULT TO CHARACTERIZE AND FEW TECHNIQUES ARE CURRENTLY AVAILABLE. THOSE THAT ARE AVAILABLE USUALLY AR ...
