THE ELECTRICAL AND MATERIAL PROPERTIES OF HIGH TEMPERATURE SUPERCONDUCTING (HTSC) THIN FILMS HAVE IMPROVED DRAMATICALLYIN RECENT MONTHS. HOWEVER, A FABRICATION PROCESS CAPABLE OFPRODUCING JOSEPHSON JUNCTIONS IN FINITE YIELDS HAS YET TO BEDEVELOPED. SOME DEMONSTRATION DEVICES HAVE BEEN MADE WHICH INDICATE THAT THE 77 K NOISE LEVELS OF DC SQUIDS MADE FROM THALLIUM-BORIUM-CALCIUM-COPPER-OXIDE ARE LOW ...

THE USE OF PEROVSKITES SUCH AS BATIO3 AS THIN FILM FERROELECTRIC MATERIALS IN MICROELECTRONICS AND PHOTONICS HAS BEEN LIMITED BY MATERIALS PROCESSING AND COMPATIBILITY PROBLEMS. HIGH QUALITY FERROELECTRIC THIN FILMS HAVE NOT BEEN GROWN AT TEMPERATURES COMPATIBLE WITH STANDARD SI OR GAAS PROCESSING TECHNOLOGY. CONSIDERING THE SUPERB ELECTRICAL AND OPTICAL PROPERTIES OF THESE MATERIALS AS WELLAS THE ...

ONE OF THE MOST IMPORTANT PROCESSES IN COMBUSTION IS THE FORMATION AND DESTRUCTION OF SOOT. THE CONCENTRATION OF SOOT CONTROLS THE ENERGY RADIATED BY THE FLAME AND HENCE THEFLAME TEMPERATURE. THE EFFECTIVENESS OF SOOT DESTRUCTION CONTROLS THE COMBUSTION EFFICIENCY AND THE ENVIRONMENTAL ACCEPTABILITY OF THE COMBUSTION DEVICE. TO PROVIDE AN INSTRUMENT FOR SOOT RESEARCH, DEVELOPMENT, AND EVENTUALLY F ...

THE MOST WIDELY USED INSTRUMENT FOR INFRARED SPECTRAL ANALYSIS IS THE FOURIER TRANSFORM INFRARED (FT-IR) SPECTROMETER. WHEN APPLIED TO NON-REPETITIVE SAMPLES THIS INSTRUMENT HAS LIMITED TIME RESOLUTION. IT IS PROPOSED TO USE A DIFFERENT TRANSFORM, A WAVELET TRANSFORM, FOR THE IR INTERFEROGRAMS, TO CONSIDERABLY IMPROVE THE TIME RESOLUTION,AND AT THE SAME TIME TO PRESENT THE RESULTS IN READILY USABL ...

ATMOSPHERIC CARBON MONOXIDE (CO) IS IMPORTANT BOTH AS AN ANTHROPOGENIC POLLUTANT AND AS A PARTICIPANT IN THE PHOTOCHEMISTRY OF THE (NOMINALLY) UNPOLLUTED ATMOSPHERE. INTHE LATTER CONTEXT, THERE EXISTS A NEED FOR A SIMPLE AND CONVENIENT INSTRUMENT TO MEASURE CO CONCENTRATIONS IN THE RANGE OF A FEW TENS OF PPB. WE PROPOSE TO DO THIS BY MEASURING THE ABSORPTION, BY THE INFRARED R16 LINE OF CO, OF THE ...

HIGH INTENSITY, SYNCHROTRON SOURCES ARE CAPABLE OF PRODUCINGA HIGH FLUX OF MONOCHROMATIC X-RAYS. THIS RESULTED IN IMPORTANT ADVANCES IN THE STUDY AND DETERMINATION OF THE STRUCTURE OF LARGE MOLECULES. ALTHOUGH THESE SOURCES REPRESENT SUCH A MAJOR ADVANCE IN TECHNOLOGY, AT PRESENT THERE ARE NO LARGE AREA DETECTORS WITH BOTH THE HIGH FLUX CAPABILITY AND GOOD SPATIAL RESOLUTION NEEDED TO MAKE USE OFT ...

THIS SBIR-RESEARCH ADDRESSES A NEW TECHNIQUE FOR IMPROVING THE WORKING PROPERTIES OF WATER-BASED CERAMIC FORMULATIONS AND THE PRODUCTION YIELDS FOR OBJECTS MANUFACTURED FROM THESE MATERIALS. THIS EXTENSIVELY USED CLASS OF MATERIALS IS EMPLOYED IN APPLICATIONS RANGING FROM CERAMIC SUBSTRATES TO BATHROOM FIXTURES TO MONOLITHIC INSULATORS USED FOR HIGH VOLTAGE TRANSMISSION LINES. WHILE MANY ADDITIVES ...
