2-(Naphthalen-2-yl)benzo[d]thiazole meso fused dipyrromethene boron difluoride dyes are synthesised and their linear and non-linear optical properties are studied. The third order nonlinear susceptibility (χ3) value obtained from the Z-scan experiment is 11.21 × 10−13 and 13.30 × 10−13 esu. T...

A type of sulfur-doped carbon (SC) was synthetized by pyrolyzing the freeze-dried gel of agarose and sulfur powder as anode material for sodium ion batteries (SIBs), and its sodium-storage mechanism was assayed by structure and electrochemical characterizations. The most sulfur atoms were doped ...

High fructose intake has been known to induce metabolic syndrome in laboratory animals and humans. Although fructose intake enhances sodium reabsorption and elevates blood pressure, role of fructose metabolism in this process has not been studied. Here we show that by ketohexokinase — the prima...

The nuclear industry has used hard chromium plate for many years but is seeking alternatives, due to the adverse health effects of Cr(VI) employed in electroplating. In this study, testing and analysis regimes for the comparison of the sliding wear performance of candidate materials have been es...

Photocatalysis is an attractive treatment method for removing hexavalent chromium (Cr(VI)) from water. Thus far, photocatalytic reduction of Cr(VI) has been investigated mostly using TiO2 photocatalysts in acidic water solutions. Here we investigate Cr(VI) removal using zinc oxide (ZnO), tungste...

Chromium compounds are still used in the context of corrosion protection in industrial products, with Cr containing organic coatings on electrical steel as an example. In order to analyse the content of hazardous Cr(VI) components, X-ray photoelectron spectroscopy (XPS) is often promoted as a no...

Selective oxidation of primary alcohols to the corresponding aldehydes by chromium trioxide under solvent free conditions are described. This new oxidation procedure is simple and affords good yields.

This work describes a selective and sensitive colorimetric approach for the detection of heavy metal Cr(VI) ions in water using the peroxidase-like property of CuS-BSA nanocomposite. CuS-BSA nanocomposite is synthesized via a simple chemical route and characterized by various sophisticated instr...

The present work deals with the study of Cr (VI) adsorption onto montmorillonite (MM) and modified montmorillonite (MMT). The modification is done by using an amine based solvent, trioctylamine (TOA). Equilibrium and kinetic experiments are carried out to determine the effect of adsorbent dose (...

The EU human biomonitoring initiative, HBM4EU, aims to co-ordinate and advance human biomonitoring (HBM) across Europe. Within its remit, the project is gathering new, policy relevant, EU-wide data on occupational exposure to relevant priority chemicals and developing new approaches for occupati...

During the ECM process, the metal workpiece is dissolved and turns into sludge which contaminates the electrolyte. To realize precise ECM with high cost-effectiveness, an electrolyte treatment system which can realize reuse of the electrolyte and maintain the electrolyte quality constant is sign...

Hexavalent chromium (Cr(VI)) compounds are classified as carcinogenic to humans. Whereas chromium measurements in urine and plasma attest to the last few hours of total chromium exposure (all oxidation states of chromium), chromium in red blood cells (RBC) is attributable specifically to Cr(VI) ...

Chromium is a naturally occurring metal found worldwide in the air, soil, and water. There are three stable naturally occurring valence states, metallic chromium [Cr(0)], trivalent [Cr(III)], and hexavalent [Cr(VI)]. Cr(VI) is an established carcinogen, while Cr(III) is considered generally safe...

We investigated the influence of Sb dopant concentration on the structural, electrical, and photoelectrochemical properties of the photocathode cuprous oxide (Cu2O) thin films. The photoabsorber p-type Cu2O films were prepared by electrodeposition in ionic electrolytes including copper sulfate a...

In the present work potassium antimony tungsten oxide with pyrochlore structure is refined by the Rietveld method (space group Fd3m, Z = 8). The temperature dependences of heat capacity have been measured for the first time in the range from 7 to 370 K for this compound. The experimental data we...

Antimony-carbon nanocomposites are known anode materials for lithium- and sodium-ion batteries that can display an attractively stable cyclic behaviour in half-cells. They can also be used for potassium-ion batteries but a similar stability is not achieved, and electrode failure (abrupt capacity...

In this study, a combined process of alkaline pressure oxidative leaching (APOL) and Na2S leaching was proposed to extract arsenic and antimony from high arsenic smelter ash. The arsenic was selectively dissolved into the leachate during APOL, while the antimony was separated into the residue as...

The effect of carbon additives on electrode formulation of bulk antimony was investigated in potassium-ion batteries. Several types of carbon including conventional carbon black, graphite and double-walled carbon nanotubes (DWCNT), employed as conductive agents, were found to play a non-negligib...

In this work, an accurate model is presented for predicting the hydrogen hydrate cage occupancies. This novel predictive method is based on the hydrate phase stability and hydrogen effective molecular size and configuration. The hydrogen-hydrogen interactions in a hydrate cage are calculated usi...

To develop high strength Al-Zn-Mg alloys, suppression of hydrogen embrittlement is indispensable. The hydrogen embrittlement behavior of different prepared Al-10.1-1.2Mg alloys with various hydrogen trap sites was observed using in situ synchrotron X-ray tomography in this study. Furthermore, we...
