quality of ground surface finish of unidirectional glass fiber reinforced plastics (effect of grinding methods)

as the first step to clarify the grinding mechanism of frp, the quality of ground surface finish of unidirectional glass fiber reinforced plastics was investigated. the present paper describes the investigation on how to produce the same quality ground surface finish irrespective of the change of glass yarn direction in the specimen and h..

new method for fabricating langmuir-blodgett films of water-soluble proteins with retained enzyme activity

a new method has been developed for fabricating monolayers of water-soluble proteins on a water surface and transferring the protein langmuir-blodgett (lb) films from the water surface monolayers of glucose oxidase (god) or cytochrome c(cyt-c) spread on 3 m (nh/sub 4/)/sub 2/so/sub 4/ solution were transferred onto the water surface with ..

improvement of heat degradation in y-tzp by surface modification

y-tzp has both high sinterability and superior mechanical properties, but the fracture strength is degraded by annealing at such low temperatures as 100 approximately 300 degrees c. in order to improve the heat degradation of tzp containing 3 mol percent -y/sub 2/o/sub 3/, a fabrication technique for surface modification of tzp was develo..

study of surface passivation as a function of inp closed-ampoule solar cell fabrication processing variables

the effects of various surface preparation procedures, including chemical treatment and anodic or chemical oxidation, closed-ampoule diffusion conditions, and post-diffusion surface preparation and annealing conditions, on the passivating properties of inp have been investigated in order to optimize the fabrication procedures of n/sup +/p..

the effect of hydrogen treatment on damaged and undamaged metal-insulator-semiconductor solar cells

a metal-insulator-semiconductor structure was used to study the effect of hydrogen plasma treatment of solar cells. cells were fabricated on single-crystal p-type silicon and treated in hydrogen plasma for different exposure times. this causes a noticeable drop in the photocurrent and density of charge carriers with exposure time. this in..

interface characterization of znse/gaas heterojunctions

znse/geas heterojunctions were fabricated by a low-temperature plasma-assisted totally dry process consisting of removal of the native oxide layer in a hydrogen plasma, surface treatment in hydrogen plasma containing se or nitrogen and epitaxial growth of znse in the same chamber. the surface states consist of defect-related surface state..

hydrocarbon reaction with hf-cleaned si(100) and effects on metal-oxide-semiconductor device quality

the surface reactivity of hydrogen-passivated, hf-cleaned si(100) towards hydrocarbon adsorption is examined by surface analysis: most hydrocarbons adsorb on the surface. dangling bonds formed during thermal processing react with fragmented organic molecules forming sic. metal-oxide-semiconductor devices fabricated on contaminated surface..

effect of composition of lubricating-cooling liquid on the fabrication quality of glass diffraction gratings

it is shown that the use of an active lcl (lubricating-cooling liquid) has made it possible to plasticize the surface layer of a glass substrate and thereby improve the fabrication quality of glass diffraction gratings

auditory nerve of the normal and jaundiced rat. i. spontaneous discharge rate and cochlear nerve histology

the functional integrity of the peripheral auditory system in the gunn rat was examined. the gunn rat is a mutant of the wistar strain with congenital deficiency of the liver enzyme uridine diphosphoglucuronyl transferase which is essential for bilirubin conjugation. this deficiency is inherited as an autosomal recessive trait with the ho..

determination and observation of electronic defect levels in cuinse/sub 2/ crystals and thin films

the effects of heat and surface treatments used in the fabrication of cuinse/sub 2/ (cis) single-crystal and thin-film solar cells are investigated, and the associated dominant defect states are identified using high-resolution photoluminescence (pl) and deep-level transient spectroscopy (dlts) measurements. the results are correlated wit..
