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...

The active centers of carbon catalysts doped with cobalt, nickel, copper, manganese, zinc, and chromium were modeled by density functional theory methods. Likewise, the thermodynamics oxygen reduction reaction (ORR) on model determined. features chemical properties chromium-containing material, namely its spontaneous oxidation into hydroxo form, revealed. In addition, it was established that am...

A feasible and fast method to fabricate hydrogen peroxide sensor was investigated by graphene-manganase nanocomposite carbone paste electrode. In the present work, in first step, the graphene was synthesized by chemical method and in second step, manganese oxide nanoparticle was doped on graphene. graphene-manganase nanocomposite was characterized by FTIR and SEM. The nanocomposite shows a high...

The synthesis of various transition-metal-doped InP quantum dots (QDs), such as copper, manganese, and silver, for enhanced optoelectronic properties has been reported to date. Herein, we introduce ruthenium (Ru) doping into QDs. After Ru doping, QDs showed a significant red shift up 325 meV due the introduction mid-gap states. optimization studies ZnS shell formation on Ru-doped core led high ...

Manganese oxide (MO) has been synthesised by chemical co-precipitation method and it was characterised for its functional group, phase structure, particle size morphology using FTIR, XRD, SEM TEM. Additionally, electrochemical properties like cyclic voltammetry (CV), galvanostatic charge/ discharge impedance spectroscopy (EIS) are recorded. The specific capacitance of the prepared manganese is ...

Manganese modulation-doped two-dimensional hole systems confined in strained InAs/InGaAs/InAlAs heterostructures were investigated by low-temperature magnetotransport experiments. The study demonstrates quantized transport phenomena in the high field region, weak anti-localization in the low-field region and ferromagnetic ordering in the separated and insulating manganese-doped layer. A signifi...
