BACKGROUND PURPOSE Photocatalytic water splitting for hydrogen evolution is a potential way to solve many energy and environmental issues. Developing visible-light-active photocatalysts to efficiently utilize sunlight and finding proper ways to improve photocatalytic activity for H2 evolution have always been hot topics for research. This study attempts to expand the use of sunlight and to enha...

The first investigation of the microwave spectrum of ethylenediamine (NH CH –CH NH ) showed that in the gas phase this molecule occurs in two conformers which both exhibit a large amplitude tunneling motion corresponding to an interchange of the roles of the amino groups. In conformer I, the tunneling splitting is about 172 MHz while it is only 2.7 MHz in conformer II. In the paper an analysis ...

let $pounds$ be the category of all locally compact abelian (lca) groups‎. ‎in this paper‎, ‎the groups $g$ in $pounds$ are determined such that every extension $0to xto yto gto 0$ with divisible‎, ‎$sigma-$compact $x$ in $pounds$ splits‎. ‎we also determine the discrete or compactly generated lca groups $h$ such that every pure extension $0to hto yto xto 0$ splits for each divisible group $x$ ...

Abstract The electronic characteristics and magnetism of nitrogen passivated armchair ZnO nanoribbons (NA8ZnONRs) by applying an electric field were analyzed using the DFT method at LDA+U level. outcomes suggest that intrinsic (A8ZnONRs) are nonmagnetic semiconductors. After passivation, NA8ZnONRs display ferromagnetism, whose (3.21 μB) primarily derives from spin polarization p orbital electro...

The response of the level anticrossing signal to a quasiresonant radio-frequency field, which appears in zero magnetic field at nitrogen-vacancy (NV) color centers diamond, is investigated. It shown that complex structure this can be explained by Autler-Townes splitting. possibility controlling parameters considered. slope central resonance recorded upon low-frequency modulation external 2.3 ti...

this paper aims to evaluate inventory cost of a two-echelon serial supply chain system under vendor managed inventory program with stochastic demand, and examine the effect of environmental factors on the cost of overall system. for this purpose, we consider a two-echelon serial supply chain with a manufacturer and a retailer. under vendor managed inventory program, the decision on inventory le...
