Currently, substantial interest is focused on developing assisted tandem catalysis to optimize the reaction conditions for each step in the process. By combining a molybdate oxidation catalyst and alkaline μ3-OH tricopper (II) cores into a metal-organic framework (MOF), a bifunctional catalyst,...

Iron molybdate thin films are studied here as a possible electrode material for future Li and Na microbatteries working in a lower potential range than currently used systems. Monoclinic Fe2(MoO4)3 thin films are successfully deposited using radio frequency (RF) sputtering and an annealing treat...

3D hierarchical flowers of Cu3Mo2O9 (CM) assembled with two-dimensional nanosheets have been fabricated via the structure transformation of the Cu3(OH)2(MoO4)2 (CMOH) nano-cuboids. The tracing in the growth process of CMOH nanocuboids reveals that CMOH nanoparticles (NPs) are first formed follow...

The neuro-protective effects of rubidium and lithium as alkali metals have been reported for different central nervous system dysfunctions including mania and depression. The aim of this study was evaluating as well as comparing the effects of rubidium chloride (RbCl) and lithium chloride (LiCl)...

The biology of the inorganic anion nitrite is linked to nitric oxide (NO) as nitrite can be reduced to NO and mediate its biological activities. Thus, studies of nitrite biology require sensitive and selective chemical assays. The acetic and ascorbic acids method is selective for nitrite and mea...

Highly sensitive detection of nitrite has drawn considerable concern owing to their destructive effect on both human health and the environment. A simple but sensitive electrocatalytic method for nitrite determination is significantly important in its real operation. Herein, a novel electrochemi...

Porous nanododecahedron of Co3O4/C has been synthesized by calcination of the ZIF-67 in air at 400 °C and then be used as electrode material for fabricating a highly sensitive and low overpotential sensor of nitrite ion (NO2−). The structure and morphology characterization show that ZIF-67 beha...

Molten salts are widely used as thermal energy storage media in the Concentrating Solar Power (CSP) technologies. The melting point and the thermal stability of the salt determine the applicable temperature range of the storage system. The focus of this paper is to evaluate the effect of differe...

This study presents new alternative molten salt mixtures as energy storage media in concentrating solar power technologies. The commercial Hitec mixture and new ternary reciprocal mixtures with lithium nitrate were studied. Various techniques were used in order to examine the thermal and rheolog...

Glutamate is an excitatory neurotransmitter implicated in the pathogenesis of psychiatric disorders. Glutamate results in the activation of an enzyme called glycogen synthase kinase-3 (GSK-3) acting through N-methyl-d-aspartate (NMDA) receptors. Impaired expression of GSK-3 affects behavior and ...

Accelerated corrosion tests of reinforcing steel in mortar containing chlorides were conducted using a lithium nitrite corrosion inhibitor focusing on the nitrite–chloride ion molar ratio (NO2-/Cl-) as a test parameter. Lithium nitrite’s corrosion-inhibiting effect was non-destructively monito...

The integrated use of two solid adsorbents with magnetic properties was studied with the aim of decontaminating an acid mine water. The adsorbents were magnetic nanostructured calcium silicate hydrate (mag-NanoCSH) and magnetic manganese dioxide (mag-MnO2), both of which consist of a crystalline...

Oxygen fugacity and melt composition are both known to have a strong influence on the partitioning of trace elements between coexisting minerals and melt. Previous work has suggested that Mn partitioning between apatite and silicate melt may be strongly affected by oxygen fugacity and could, the...

Supercapacitor performance is reported for manganese silicate hybridized carbon materials (MnSi-C) that is derived from natural bamboo leaves. The in-situ generated manganese silicate is in good distribution by a simple hydrothermal treatment without the addition of another controlling agent. We...

Manganese ores differ extensively in their mineralogical and bulk chemical composition. Consequently these ores follow different mineralogical morphology development paths as the reduction reaction proceeds in the production furnace. Mineralogical factors such as composition and distribution of ...

Electrolytic manganese residue (EMR) is a solid waste generated in filters after sulphuric acid leaching of manganese carbonate ore, which contains manganese, ammonia nitrogen and heavy metals that cause damage to environment. In fact, leaching and recovery of manganese and ammonia nitrogen from...

The influences of sodium silicate on manganese electrodeposition in sulfate solution were investigated. Manganese electrodeposition experiments indicate that a certain amount of sodium silicate can improve cathode current efficiency and initial pH 7.0–8.0 is the optimized pH for high cathode cu...

The analysis of iron, manganese and antimony in silicate glass is of great interest in chemistry, materials science, earth sciences and archaeological sciences.
