For the recovery of nuclear materials from spent fuel, a novel reprocessing process based on sulfide chemistry has been proposed. In this paper, the sulfurization behavior of thorium and uranium oxides was studied using carbon disulfide. When U3O8 was reacted with CS2, it was reduced to UO2 at t...

Palladium selenides, PdSe, Pd3Se and PdSe2 have been prepared by the hydrothermal method and investigated for their structural and electrocatalytic properties toward the oxygen reduction reaction (ORR) using SEM/TEM, XRD, cyclic and linear sweep voltammetries. The crystallites of PdSe and PdSe2 ...

This study aimed at elucidating SS-bonds of HMW-gliadins (HGL) from wheat with the focus on terminators of glutenin polymerisation. HGL from wheat flour extracts non-treated or treated with the S-alkylation reagent N-ethylmaleinimide (NEMI) were compared. HGL from wheat flour Akteur were isolate...

ObjectiveThe aim of this study was to investigate dynamic thiol–disulphide homeostasis in patients with idiopathic Parkinson’s disease and to determine its relationship with the clinical stage as assessed by the modified Hoehn and Yahr scale.

Pyridine Nucleotide-Disulphide Oxidoreductase Domain 2 (PYROXD2), a Hepatitis B virus X protein (HBx)-interacting protein, is significantly down-regulated in hepatocellular carcinoma (HCC), however its exact biological function remains unclear. The aim of this study is to investigate the subcell...

Benzyl disulphide has been used as an ionophore and dimethylsebacate as a plasticizer in order to develop a poly(vinyl chloride)-based membrane electrode for lead ion detection. The electrode exhibits good properties with a Nernstian slope of 29.2±1.3 mV per decade and a linear range of 2×10−5...

ObjectivesTo develop a novel and automated assay determining plasma thiol/disulphide homeostasis, which consists of thiol–disulphide exchanges.

The structural changes resulting from the reduction of disulphide bonds in three globular proteins (albumin, chymotrypsin and thrombin) in aqueous solutions are investigated using Raman spectroscopy. Changes in SS and SH vibrational bands are used for direct observation of the disulphide bond re...

A proposed Ag/WS2/SiO2/p-Si/Ag Schottky heterostructure photodetector is tested for its photoconduction behaviour under ultraviolet (UV) illumination using a light emitting diode (LED) at 380 nm. This is done at various illumination powers as well as different direct current (DC) bias voltages. ...

Bipolar disorder (BD) patients have increased oxidative stress, which can disturb thiol/disulphide homeostasis, causing disulphide formation. The aim of the study is to investigate dynamic thiol/disulphide (SH/SS) homeostasis in BD patients, which is a novel evaluation method of oxidative status...

Nano-scale molybdenum disulphide sheets with large sulphur-rich surfaces could function as excellent scavengers for cadmium ions, based on the affinity of S to heavy metals. In this work, nano-scale molybdenum disulphide sheets were applied for cadmium uptake from aqueous solution. Transmission ...

PurposeAnti-epileptic drugs have been widely used in children with epilepsy. Although several studies have investigated the role of oxidative stress and the effects of antiepileptic drugs on several oxidative markers in epilepsy, adequate information is not available on this issue. This study ai...

The oxygen fugacity in Hydrothermal Diamond Anvil Cell (HDAC) experiments was determined by means of direct observation of the thermal reduction of molybdite or hematite in water and water–H2O2 solutions. HDAC experiments were conducted with and without rhenium gasket in order to evaluate the e...

The electrodeposition of MoxRe1−xOy films (0.6 ≤ x ≤ 1) on indium-tin oxide (ITO) coated glass substrates from acidic peroxo-polymolybdo-perrhenate solutions is described. Trends in film growth were established as a function of potential from +0.4 V to −0.7 V vs Ag/AgCl by analyzing the compos...

The perovskite-type compounds containing both rare earth and rhenium Sr2LnReO6 (Ln=Y, Tb-Lu) have been prepared. Powder X-ray diffraction measurements and Rietveld analysis show that Ln3+ and Re5+ ions are structurally ordered at the B site of the perovskite SrBO3. Magnetic anomalies are found i...

Kazakhstan is a major producer of non-ferrous metals. The production of heavy metals is generally based on pyrometallurgical processes resulting in the generation of by-products which contain rare metals, in particular rhenium. The base mineral raw materials for recovery of rhenium are solid and...

The investigation aims at a hydrometallurgical processing approach for an environmentally hazardous material called “Theisenschlamm”, which is a flue dust of former copper shale processing in Germany. Besides eliminating the negative environmental impact, processing of this material would also...

Nanoparticles of rubidium-doped gadolinium titanates oxide were prepared by the sol–gel process from the titanium alcoxyde Ti(OBu)4 and the two oxides Rb2CO3 and Gd2O3. Thermal gravimetric (TG) and differential thermal analysis (DTA) results suggest that thermal decomposition of the xerogel tak...

The electrophysical reaction of rubidium polytungstate Rb4W11O35 (RWO) on fast humidity impact has been investigated by studying the influence of wet air pulse of 1–3 s of duration on the peculiarities of dynamic current–voltage (I–V-) and charge-voltage (Q–V-) loops and transient current–t...

Since photocatalytic reactions are almost consistent with the concept of green chemistry, substance conversion using photocatalysts has recently attracted the attention of researchers in the fields of organic chemistry, physical chemistry and material chemistry. We investigated photoinduced ring...
