THE ADVANTAGES OF THERMOPLASTIC MATRIX COMPOSITES FOR MANUFACTURING LOW-COST CMPONENTS HAVE YET TO BE REALIZED. AN IMPORTANT FACTOR LIMITING THERMOPLASTIC COMPOSITES IS THE LACK OF LOW-COST METHOD FOR PRODUCING HIGH-QUALITY PREPREGS AND PREFORMS. A METHOD OF PRODUCING THESE MATERIALS THAT IS COMPATIBLE WITH COMMONLY USED COMPOSITE FABRICATION TECHNIQUES SUCH AS FILAMENT WINDING, PULTRUSION, AND PR ...

THE POSSIBILITY THAT ATOMIC CHLORINE CONCENTRATIONS IN THE MARINE SURFACE LAYER ARE LARGE ENOUGH TO COMPETE WITH OH AS THE MAJOR TROPOSPHERIC OXIDIZER HAS RECEIVED CONSIDERABLE SPECULATION. CHLORINE ATOMS PARTICIPATE IN THE OXIDATION OF HYDROCARBONS AND DIMETHYL SULFIDE AND CAN ALSO DIRECTLY INFLUENCE TROPOSPHERIC OZONE LOSS THROUGH CATALYTIC CYCLES WITH C1O AND HO2 RADICALS. THE NET EFFECT ON T ...

This Small Business Innovation Research Phase II project will develop a new analytical tool for characterizing drug delivery aerosols and powders. This instrument will be based on a previously developed aerosal mass spectrometer that provides real-time size distribution and chemical composition measurements for aerosol particles. During Phase I research, a new inlet for the aerosol mass spectromet ...

This Small Business Innovation Research (SBIR) Phase II project concerns the development of an optical alloy composition sensor based on laser induced plasma spectroscopy. A key element of the sensor is the use of a microchip laser excitation source. The technology has the capability to detect industrially relevant compositions in steel alloys and possibly aluminum alloys. The Phase I results in ...
