magnetron co-sputtering system for coating icf targets

fabrication of inertial confinement fusion (icf) targets requires deposition of various types of coatings on microspheres. the mechanical strength, and surface finish of the coatings are of concern in icf experiments. the tensile strength of coatings can be controlled through grain refinement, selective doping and alloy formation. we have..

this project is to have domestic industries accumulate the know-how by developing fabrication technology and to establish the quality assurance program necessary for the manufacturing of nuclear grade components. kaeri performed the preparation of detail drawings, technical specifications, design analysis and test and evaluation of the pr..

photoelectrolysis of water for production of hydrogen. final report, 1 march 1979-8 march 1981

no single chemical compound meets all the requirements for catalytic electrodes to be used in photoelectrolysis. three different approaches toward the development of materials for such electrodes have been investigated. composite structures have been prepared by depositing sputtered cdse-srtio sub 3 and cdse-tio sub 2 films on cdse substr..

thermoplastic elastomers: a review of current information,

these materials represent some of the most important developments in the polymer industry in recent years. thermoplastic elastomers combine the mechanical properties of vulcanized rubbers with substantially greater thermoplasticity than rubber-like plastics they can be processed, and even reprocessed, by standard thermoplastic techniques ..

carcinogenesis bioassay of c.i. acid red 14 in f344 rats and b6c3fl mice (feed study)

a carcinogenesis bioassay of textile grade c.i. acid red 14 (67-71 purity) was conducted by feeding diets containing 6,000 or 12,500 ppm of this dye for 103-104 weeks to groups of 50 male f344 rats, 12,500 or 25,000 ppm to groups of 50 female f344 rats and 3,000 or 6,000 ppm to groups of 50 b6c3f1 mice of either sex. groups of 90 untreate..

the labor market impact of hispanic undocumented workers: an exploratory case study of the garment industry in los angeles county

the study seeks to determine whether hispanic undocumented workers are occupying jobs in the garment industry in los angeles county that might otherwise be held by unemployed black and hispanic u.s citizens and legal immigrants. the data gathered suggest that the majority of the garment workers in los angeles are hispanic undocumented and..

a module experimental process system development unit (mepsdu)

design work for a photovoltaic module, fabricated using single crystal silicon dendritic web sheet material, resulted in the identification of surface treatment to the module glass superstrate which improved module efficiencies. a final solar module environmental test, a simulated hailstone impact test, was conducted on full size module s..

industrial hygiene report, perchloroethylene, g.f. thomas cleaners, san francisco, california,

worker exposure to perchloroethylene (127184) (pce) was determined at g. f. thomas cleaners (sic-7216) in san francisco, ca. on july 25, 1978. the firm was included in an industry wide mortality and industrial hygiene study of dry cleaning workers exposed to pce. the work force included a dry cleaner and spotter, finishers, and counter he..
