Structural relaxation and viscosity of Al2O3 doped magnesium phosphate glasses

Structural relaxation in chalcogenide glasses

“…The R f (10) plotted as a function of σ for chalcogenide glasses (Table 1) is depicted in Figure 4, along with data for some oxide glasses 41–49 and organic polymers, such as polystyrene (PS), 50,51 polycarbonate (PC), 52 polyvinyl acetate (PVAc), 53,54 epoxy resin, 55 polymethyl methacrylate (PMMA), 51,53 polyethylene terephthalate (PET), 56 and polyvinyl chloride (PVC) 51 …”

“…The isothermal relaxation rate for ΔT = 10 K, calculated by Equation ( 13) for ß = 0.9 and 0.5 (blue solid lines). Points correspond to the Tool-Narayanaswamy-Moynihan (TNM) parameters reported for chalcogenide glasses (see Table 1), oxide glasses, [41][42][43][44][45][46][47][48][49] and organic polymers: polystyrene (PS), 50,51 polycarbonate (PC), 52 polyvinyl acetate (PVAc), 53,54 epoxy resin, 55 polymethyl methacrylate (PMMA), 51,53 polyethylene terephthalate (PET), 56 and polyvinyl chloride (PVC). 51 as polystyrene (PS), 50,51 polycarbonate (PC), 52 polyvinyl acetate (PVAc), 53,54 epoxy resin, 55 polymethyl methacrylate (PMMA), 51,53 polyethylene terephthalate (PET), 56 and polyvinyl chloride (PVC).…”

Heterogeneous UV disinfection aided by ZnO/Al2O3 composites for inhibiting antibiotic resistant bacteria photoreactivation and gene recovery

“…Aluminum oxide may be a suitable carrier for nanomaterial because of its properties of acid, alkali and oxidization resistances, extreme insolubility in water and uneasy reaction with metal ions and organic matters. 41,42 In this study, a composite particle, ZnO@Al 2 O 3 , where nano-ZnO loaded on Al 2 O 3 surface was synthetized through the template and hydrothermal synthesis. A disinfection system with the integration of UV-C irradiation and ZnO@Al 2 O 3 particles was set up to inhibit the photoreactivation phenomenon and tagged as UV-ZnO@Al 2 -O 3 .…”
