Water Purification The image representing article 2200039 by K. Y. Sandhya and co-workers is a symbolic depiction of partially reduced graphene oxide-molybdenum disulfide nanocomposite (prGO-MoS2) for the ultra-rapid selective removal Pb(II) ions from contaminated water within ?3 minutes in presence other ions, due to interaction electrochemistry between S2? oxygen moieties prGO-MoS2.

Using a 10 nm thick molybdenum oxide (MoO3-x) layer as a transparent and low barrier contact to p-CdTe, we demonstrate nanowire CdS-CdTe solar cells with a power conversion efficiency of 11% under front side illumination. Annealing the as-deposited MoO3 film in N2 resulted in a reduction of the cell's series resistance, from 9.97 Ω/cm(2) to 7.69 Ω/cm(2), and increase in efficiency from 9.9% to ...

Although molybdenum oxide tetrachloride was first reported more than a century ago [1] the compound has been satisfactorily characterised only recently [2]. A gas-phase electron diffraction study is available [3] but the structure in the solid has not previously been described. However, it has been suggested that the solid state structure "is similar to that of WOCI4 on the basis of physical pr...

The crystal structure of the title compound, dilithium germanium trimolybdenum octa-oxide, consists of distorted hexa-gonal-close-packed oxygen layers with stacking sequence ABAC along [001] that are held together by alternating lithium-germanium and molybdenum layers. The two Li(+) and Ge(4+) ions all have site symmetry 3m. and occupy, respectively, tetra-hedral and octa-hedral sites in the ra...

Molybdenum oxide (5 to 20 wt.%) supported on calcium or strontium hydroxyapatite were investigated as catalysts for selective oxidation of methanol formaldehyde. These both active and selective, with a maximum yield achieved at 95 % conversion 96 selectivity. The main byproducts CO (3.2 %) dimethyl ether (DME, 0.7 %). catalytic performance the was measured up 600 h 350 °C. Compared an industria...

The high-temperature oxidation and the thermal destruction of electrically heated tungsten molybdenum filaments in air arestudied experimentally. temperature histories are obtained, successive stages defined. It isshown that phase transition points oxides determine limits these stages. filament conditions established: diameter central zone, electric current corresponding to failure, as well bur...

Abstract Inorganic two-dimensional membranes offer a new approach to modulating mass transport at the nanoscale. These membranes, which can harness van der Waals gap as nanochannel and address persistent challenges in organic are limited few material libraries, such graphene, graphene oxide, molybdenum disulfide, boron nitride. Here we report for first time development of cation-selective layer...
