Density functional theory investigation of oxidation intermediates on gold and gold-silver surfaces
(Amer Chemical Soc, 2020)Gold and gold-silver alloys can be active and selective oxidation catalysts. Previous work has suggested that O-2 dissociation occurs at bimetallic step sites on gold-silver alloys, but the site responsible for the rest ... -
Dependency of c-lattice parameter, activation energy and its magnetic power constant on x in Y1-xYbx/2Gdx/2Ba2Cu3O7-y superconductors
(Elsevier, 2008)To investigate the effect of x on c-lattice parameter, the activation energy, and the magnetic power constant of activation energy, the nominal composition of Y1-xYbx/2Gdx/2Ba2Cu3O7-y superconducting samples for x = 0.0, ... -
Deposition and characterization of the Ag nanoparticles on absorbable surgical sutures at the cryogenic temperatures
(Springer Heidelberg, 2023)Surgical sutures are one of the most widely used medical devices for wound closure. In the meantime, the suture surface and area may be exposed to many microorganisms, and surgical site infections may develop in these ... -
Deposition of CdSeTe alloys using CdTe-CdSe mixed powder source material in a close-space sublimation process
(Springer, 2021)CdSexTe1-x films were deposited using a close-space sublimation (CSS) method and CdSe + CdTe mixed powders as the source material. Composition of the source was changed to obtain films with varying x values, and the resulting ... -
