The interaction of light with semiconducting materials becomes the center a wide range technologies, such as photocatalysis. This technology has recently attracted increasing attention due to its prospective uses in green energy and environmental remediation. characterization electronic structure semiconductors is essential deep understanding photocatalytic process since they influence govern a...

A new compound was confirmed to be formed at around the composition Li:Ti:Nb=19:10:12 in the system Li 0-Ti0 -Nb O5 by reaction at 1100 OC for 2 120 hrs in air betaeen tf2~63, Ti0 and Nb205. This compound was also produced by reactlon of L~N~o,.o.~T~o, with Li2Ti0 . Single crystals of the compound were grown uslng a Li2Mo04 8y flux method. The crystals were shown to possess a hexagonal symmetry...

Lignin is an integral part of the plant cell wall, which provides rigidity to plants, also contributes to the recalcitrance of the lignocellulosic biomass to biochemical and biological deconstruction. Lignin is a promising renewable feedstock for aromatic chemicals; however, an efficient and economic lignin depolymerization method needs to be developed to enable the conversion. In this study, w...

Cast refractory alloys Mo–Nb–Si–B were prepared by centrifugal self-propagating high-temperature synthesis (SHS) from metallothermic mixtures containing MoO3, Nb2O5, Al, Si, and B powders, additive of Al2O3 as a temperature-moderating chemically inert agent. Variation in the acceleration amount affected composition structure cast alloys. In wide range values, combustion temperature was found to...
