Current chemistries used to modify the surfaces of metal oxide semiconductor films are susceptible to hydrolysis and degrade at high, positive potentials. Amorphous carbon (aC) films are an attractive alternative to metal oxides for the preparation of chemically modified electrodes, with surface...

Manganese neurotoxicity is characterized by Parkinson-like symptoms with degeneration of dopaminergic neurons in the basal ganglia as the principal pathological feature. Manganese neurotoxicity studies may contribute to a good understanding of the mechanism of Parkinson's disease (PD). In t...

Single crystals of bisthiourea manganese chloride (BTMC) mixed with nickel chloride were grown by slow evaporation solution growth technique using water as solvent in a constant temperature bath designed by the authors. The lattice parameters of the grown crystals are measured from X-ray diffrac...

A number of published studies have suggested that high levels of exposure to manganese, especially those found in occupational settings, can adversely affect the reproductive system. The objective of this study was therefore to investigate if these findings can be replicated using the Sprague Da...

In the present work, by using atomic force microscopy (AFM), the existence of periodic steps facilitates an aligned layer-over-layer (LOL) growth has been investigated for glycine manganese chloride (GMC) crystal. Nucleation and growth kinetics renders the information about the crystal growth pr...

The organo-metal material of Glycine Manganese Chloride has been grown by solvent evaporation solution growth method. Single crystal XRD study has been carried out to confirm the grown crystal.

Recovery of valuable metal from industrial waste is critically important for wastewater treatment and recycling. In the present work, we developed a new method for selective copper extraction from the actual industrial manganese-copper chloride leaching liquor, which was produced in wet extracti...

In the course of the basic research on the ammonia-evaporation reaction of manganese monoxide (MnO), hydroxyl manganese chloride (Mn2(OH)3Cl) was found. The solubility and phase diagrams of the hydroxyl manganese chloride were investigated. The aqueous thermostat and vibrating bed were used to d...

Thermal energy storage plays a key role in the application of renewable energy and low-grade thermal energy. A laboratory test unit of thermochemical heat storage with manganese chloride (MnCl2) as the reactive salt and ammonia (NH3) as the working gas was constructed, in which expanded graphite...

Manganese neurotoxicity presents with Parkinson-like symptoms, with degeneration of dopaminergic neurons in the basal ganglia as the principal pathological feature. Manganese neurotoxicity studies may contribute to a better understanding of the mechanism of Parkinson’s disease. Here, we examine...

Single crystals of α and γ glycine manganese chloride (GMC) were prepared using four dopant concentrations of MnCl2 in the molecular formula (C2H5NO2)1−x(MnCl2)x, where [x = 0.005, 0.02, 0.04, 0.05]. The crystals showed: nonlinear optical (NLO) activity, high transparency in UV–Vis. range of ...

Suppository bases were formulated from mixtures of hydrogenated cottonseed oil and hexadienol with various other ingredients. Suppositories were prepared from these bases that were satisfactory with respect to appearance and consistency. The potential of the bases to release a medicament was det...

Catalytic hydrogenation of (2E,4E)-hexadienol over Pt, Pd, Rh, Ru and Ni supported on active carbon and γ-alumina has been studied. In all the reactions, diverse isomers of alkenic hexenols were primarily produced, which further hydrogenated to hexanol. Various hexenals were identified in the r...

Improvement in wear resistance and hardness of cutting tool material is one of the most important challenges in machining operation. This issue can be overcome by improving the wear resistance and hardness by cryogenic treatment of tungsten carbide. In this work it is tried to study the effect o...

Tungsten carbides, which can be widely used as cutting and drilling tools, chemical catalysts and aerospace coatings, have attracted widespread attentions. The present work reported a simple method to prepare tungsten carbides by using WO2 as the raw materials and CO as the reduction and carboni...

The aim of this study was to produce dense, single phase polycrystals. The research was carried out on the submicron tungsten carbide powder without additives, with either a carbon or tungsten additive and on the powder with both additives. The primary task of carbon was to reduce surface oxide ...

High-pressure strengthening is reported to be an effective approach to strengthen materials in addition to traditional nanocrystalline strengthening. Numerous studies have proven that high pressure is an important factor for improving the mechanical properties of materials. Here, we sintered hig...

3D network-like tungsten carbide-carbon nanotubes composites were in-situ synthesized by using W18O49 as the precursor. The sea urchin like W18O49 with abundant oxygen defects was designed and fabricated to act as not only the source of tungsten, but also the catalyst to initiate the growth of c...
