Self-assembled ensembles of a disulphide derivative of para tertiary butyl calix arene 1,3 acid amide on polycrystalline gold have been shown to exhibit an electrochemical response proportional to the concentration of uranium in solution. This response is related to microscopic changes at the el...

It is significant to develop novel materials and techniques for efficient removal of radionuclides from radioactive wastes due to the radioactive and chemical toxicity. In this paper, we report a strategy for broad-spectrum adsorption of radionuclides by multiple groups-decorated adsorbents. Spe...

The Baxingtu deposit is a typical redox front tabular-shaped uranium deposit hosted in sandstones of the Late Cretaceous Yaojia Formation deposited within a braided river environment during the post-rift stage of the Songliao Basin, in northeast China. This study proposes the first metallogenic ...

The mechanism was investigated of hydrogen sulfide splitting in alkaline aqueous solutions using spray-pyrolysed SnIV-doped α-Fe2O3 photo-anodes in a photo-electrochemical cell. In principle, hydrogen sulfide splitting can be used to treat hydrogen sulfide in natural and process gases and simul...

The structures of tin monosulfide (SnS) with the surface modified by ultrathin titanium(IV) oxide layers for potential photoinduced water splitting were successfully fabricated. SnS thin films were deposited onto glass/Mo substrates using high vacuum evaporation (HVE) method, and then a simple a...

The effect titanium additions (0.01 wt.%) have on sulphides in low carbon, low manganese (0.3 wt.% Mn) steels was investigated by transmission electron microscopy. It was found that the titanium additions lead to the formation of a hexagonal iron titanium sulphide. The crystal structure of the i...

After the discovery of a few cases of lower enantioselectivity in the oxidation of aryl benzyl sulfides with hydroperoxides in the presence of a complex between titanium isopropoxide and (S, S)-hydrobenzoin, a screening of the oxidation of new substrates that are related to the structures that g...

Metal sulfide semiconductor nanostructures represent the most promising group of nanostructured materials with excellent optical and electrical properties for such applications as photoelectrochemical cells, photocells, photoconductors, infrared detectors, nonvolatile memory devices and resistiv...

Anaerobic digestion for biogas production is one of the most used technology for bioenergy. However, the adoption of nanoparticles still needs further studies. Therefore, this study was designed to examine the effect of metal oxide nanoparticles (MONPs) at four different concentrations in two di...

Herein, cadmium sulfide–sensitized titanium dioxide (CdS/TiO2) deposited on a fluoride-doped tin oxide electrode is proposed for achieving the photoelectrocatalytic (PEC) degradation of methylene blue (MB). Under optimum conditions (six accumulative CdS depositions, 3.0-V DC applied biased pote...

This study assessed the corrosion behavior of titanium in response to sulfide by determining the effects of sulfide concentration and pH over immersion period. Corrosion was evaluated through changes in color, glossiness, surface characterization, and titanium release. Sulfide solutions were pre...

The influence of sulfides on the passivation behavior of titanium alloy TA2 in simulated seawater environments was studied by electrochemical methods, surface topology and X-ray photoelectron spectroscopy (XPS). Cyclic voltammetry analysis reveals that the passivation process of titanium TA2 was...

ObjectiveTo investigate the effects of sulfides produced by Porphyromonas gingivalis (P. gingivalis) on the corrosion behavior of titanium.

Intralesional therapy has been shown to be an effective treatment for tumors. In this study, the suitability of [188Re]rhenium sulfide suspension for tumor treatment following intra-tumor injection was evaluated. The [188Re]rhenium sulfide suspension was radiolabeled with 188Re with a radiochemi...

Rhenium is greatly enriched in black shales and euxinic basin sediments relative to its crustal abundance. The enrichment process is generally assumed to involve reduction of ReO4−, the principal Re species in seawater, to an insoluble ReIV oxide or sulfide in suboxic and anoxic environments. Th...

The behaviour of soluble rhenium(V) oxohalide complexes with coordinatively bound thiourea, triphenylphosphine and their derivatives has been studied in the hydrogenation of C6-C10 olefins, nitrobenzene and p-nitrotoluene. Under homogeneous conditions rhenium complexes containing a Re-S bond wer...

Rhenium sulfide colloidal nanoparticles with average size 5.5 nm were synthesized. Characterizations by ultraviolet–visible spectrophotometry, transmission electron microscopy, energy dispersive X-ray spectrum, and X-ray powder diffraction verified the formation of ReS2 rhenium sulfide colloida...

Literature data published mainly during the two last decades and dealing with the preparation, structure and catalytic activities in hydrotreating reactions with rhenium sulfide has been reviewed. These compounds have been particularly evaluated in model compounds reactions as thiophene hydrodes...

Rhenium, in the form of ammonium perrhenate was recovered from Sarcheshmeh molybdenite concentrates by roasting the concentrates with slaked lime.
