Mn doped ZnO nanocomposite thin film coated on glass by a simple spin-coating method was used to degrade an azo textile dye from aqueous environment. Mn doped ZnO nanocomposite thin film was characterized by means of X-ray diffraction (XRD) and scanning electron microscopy (SEM). The photo-reduction activity of photocatalyst was evaluated using an azo textile dye as organic contaminant irradiat...

Abstract The wastewater containing phenol is harmful, and the process complicated, photocatalytic oxidation technology believed to be greenest promising strategy for contaminants removal because of solar energy utilization no additional oxidants. Herein, manganese dioxide(MnO 2 ) doped with metal was fabricated by a low-temperature hydrothermal method, specific surface area MnO photocatalyst si...

in this paper we propose and simulate a new heterostructure mesfet, called δ-doped ldd hmesfet. to improve carrier velocity in vicinity of the source in channel of gaas mesfet, one can replace source with alxga 1-x as. by increasing al content, discontinuity of hetero-interface could be increased. therefore, the velocity increases in the low field. however, increasing al mole fraction in excess...

Taking the pseudobinary C15-Laves phase compound Ce(Fe 0.96 Al 0.04) 2 as a paradigm for studying a ferromagnetic(FM) to antiferromagnetic(AFM) phase transition, we present interesting thermomagnetic history effects in magnetotransport measurements across this FM-AFM transition. We argue that these distinctive hysteretic features can be used to identify the exact nature first order or second or...
