This communication examines the effect of the surface morphology of polycrystalline copper on electroreduction of CO(2). We find that a copper nanoparticle covered electrode shows better selectivity towards hydrocarbons compared with the two other studied surfaces, an electropolished copper electrode and an argon sputtered copper electrode. Density functional theory calculations provide insight...

Argon isotope studies of samples returned from the 2010 expedition to Tibet showed that the tested andesines from Yu Lin Gu and Zha Lin contained high concentrations of radiogenic argon and indicated that they had not been subjected to a copper diffusion process.

The pathologic potential of gastric inlet patches is now being recognized. A recent adult study has shown the effectiveness of argon plasma coagulation in ablating the patch and the associated symptoms. There are no reports of ablation in children. We report a case series of successful argon plasma coagulation of gastric inlet patches and their symptoms in 5 children.

This study investigated the inactivation efficiency of cold atmospheric pressure plasma treatment on Bacillus subtilis endospores dependent on the used feed gas composition and on the surface, the endospores were attached on. Glass petri-dishes, glass beads, and peppercorns were inoculated with the same endospore density and treated with a radio frequency plasma jet. Generated reactive species ...

General Considerations: All air and water sensitive procedures were carried out either in a Vacuum Atmosphere glove box under argon, or using standard Schlenk techniques under argon. Labeled solvents, D2O and CD3CN were purchased from Cambridge Isotopes and used without further purification. CD3CN was dried over CaH2 and distilled for NMR used for compound characterizations. 2,2’-bipyridine (La...

This manuscript describes the commissioning of Mini-CAPTAIN liquid argon detector in a neutron beam at Los Alamos Neutron Science Center (LANSCE), which led to first measurement high-energy interactions argon. The consists Time Projection Chamber (TPC) with an accompanying photomultiplier tube (PMT) array sealed inside liquid-argon-filled cryostat. is constantly purified and recirculated closed...
