15 صفحه اولCavitation instabilities in plastics and rubber-modified plastics
Spherical void expansion in plastics and rubber-modified plastics is investigated under radial traction conditions. The plastics are modeled as elastic-plastic pressure-sensitive materials and the rubbers are modeled as nonlinearly elastic materials. First, the growth of a spherical void in an infinite plastic matrix is investigated under remote radial traction conditions. The results show that...
متن کاملReaction of the sterilant, ethylene oxide, on plastics.
Ethylene oxide (ETO) in the form, "Cryoxcide,"' is used to sterilize surfaces and objects that cannot be treated with heat or corrosive chemicals. Cryoxcide is a gaseous formulation consisting of 11 per cent of ethylene oxide, 44.5 per cent of trichloromonofluoromethane (Freon 11), and 44.5 per cent of dichlorodifluoromethane (Freon 12). Cryoxcide is used at this laboratory to sterilize sensiti...
متن کاملUtilising polyphenylene oxide for high exposure solar UVA dosimetry
A personal UV dosimeter that can quantitatively assess high exposure solar UVA exposures has been developed. The chemical polyphenylene oxide has been previously reported on its ability to measure high UVB exposures. This current research has found that polyphenylene oxide, cast in thin film form, is responsive to both the UVA and UVB parts of the solar spectrum. Further to this, the UVB wavele...
متن کاملReactive oxygen species accelerate degradation of anion exchange membranes based on polyphenylene oxide in alkaline environments.
Anion exchange membranes (AEM) based on polyphenylene oxide (PPO) suffered quaternary-ammonium-cation-site degradation in alkaline environments. Surprisingly, the degradation rate was considerably faster in the presence of molecular oxygen. We postulated that the AEM cation-site catalyzes the reduction of dioxygen by hydroxide ions to yield the superoxide anion radical and the highly reactive h...
