Identification of the active center is pivotal to manipulate the catalyst design for the oxygen evolution reaction. Herein, sulfur was introduced to partly occupy oxygen location in the surface structure of cobalt (II) oxide. The heterogenous ‘O-Co-S’ sites brought an enhanced oxygen evolution...

Recent century is enduring a passionate development of hardback electronic devices that promised to be more reliable power sources with higher energy density and long-term stability. To push up the energy density limit of solid-state symmetric supercapacitor (SSC) devices here we report RGO-muff...

Several Pt(IV) prodrugs containing SAA, a histone deacetylases inhibitor, were designed and prepared for multiply targeting genomic DNA, histone deacetylases and PARP-1. The resulting Pt(IV) prodrug had significantly strong antiproliferative activity against the tested cancer cell lines, especia...

Kinetics of the reduction of platinum (IV) was studied by ascorbic acid in an hydrochloric acid medium. The reaction was found to have first order dependence in ascorbic acid and hexachloroplatinate ion. H+ ion showed a retarding effect and the rate of reaction varied linearly with [H+]−1. Influ...

Tin hexachloroplatinate (SnPtCl6) films have been prepared by mixing Sn2+ and PtCl62− ions in an aqueous KCl solution. An electrochemical quartz crystal microbalance (EQCM), a rotating ring-disk electrode, UV–Vis absorption spectroscopy, and cyclic voltammetry were used to study the deposition ...

In this study, poly(allylamine hydrochloride) (PAA/HCl) was cross-linked with fermentation bacterial waste (Escherichia coli) in order to introduce a large amount of amine groups as binding sites for potassium hexachloroplatinate(IV), as a model anionic pollutant. The sorption performance of PAA...

La1−xNdxPO4 monazite-type ceramics were synthesized by precipitation and sintering. The obtained crystalline powders and pellets were structurally characterized by X-ray diffraction, electron microscopy, and infrared and Raman spectroscopy. The determined unit cell constants agree with published...

Nodular monazite occurs in metamorphic rocks worldwide and has zonal REE patterns. This paper focuses on the composition of nodular monazite hosted by Permian black shales of the Kular Ridge in the Kular-Nera terrane. This monazite variety (called kularite in the Russian literature) reaches comm...

Rare earth elements (REE) are key components of many emerging green technologies. This leads to an increase in demand for REE, hence to the development of new deposits, such as the Niobec carbonatite rare earth deposit in Quebec, Canada. One of the valuable minerals in this deposit is monazite, ...

Fissure monazite-(Ce) (hereafter called monazite) commonly crystallizes during deformation at low metamorphic grade and offers the possibility to date protracted deformation over several millions of years and to identify distinct deformation phases. We performed Th-Pb geochronology at the micros...

This paper is a testimony of how electron microprobe dating of monazite was developed in the early days of this technique, in the 90's. Five contributions have been collected from Nagoya, Clermont-Ferrand, Orléans, Salzburg, and Amherst. The technique was designed in Nagoya by Professor Su...

The adsorption of carboxylate collectors is largely assumed to be affected by the monazite surface speciation. In order to provide key information for the understanding of this phenomenon, we propose in this study a thermodynamic model for the equilibrium of monazite-(La) crystal in an H2O-CO2 s...

The Manangotry area in the South-East of Madagascar is famous for its giant monazite crystals. The studied occurrence is an outcrop near the Manangotry pass, were giant, cm-sized crystals have been found. The crystals are embedded in biotitite levels, also containing cm-sized xenomorphic ilmenit...

The present paper reports an improved process using cheaper reagent at atmospheric conditions compared to the expensive pressure leaching technique (Temperature = 140 °C) as well as other processes available at higher temperature. An effective baking reagent, potassium hydroxide (KOH) was used ...

Metastable Ln-orthophosphates (Ln = Tb, Dy) with monoclinic monazite-type structure were obtained via a precipitation route in aqueous solutions and subsequent thermal treatment. The lattice parameters and fractional coordinates of the atoms in the crystal structures were determined by Rietveld ...

The equilibrium geometries and thermodynamic properties of anion vacancies in cadmium telluride, as predicted by density functional theory, are revisited using semilocal and hybrid density functionals. We find that stable configurations in different charge states can only be found after a system...

During present investigations, renal toxicity of CdSNPs (cadmium sulphide nanoparticles) (ranged 5–9 nm) was estimated in rat employing specific parameters. Treatment on each alternate day for 45 days with CdSNPs (10 mg/kg b.w.) yielded significant increase in Cd-MT (cadmium metallothionein), l...

The Cadmium sulphide/bio-structured carbon composites are synthesized by a novel combination of calcination method and hydrothermal method. The purpose of converting the exposed face of the material from the (101) crystal to the (002) crystal plane is achieved by adding EDTA to the solution syst...

Electrolyte contacts were used to characterize cadmium sulfide (CdS) films grown by chemical bath deposition on fluorine-doped tin oxide glass (FTO). Capacitance measurements were made in a buffered electrolyte free of redox species, and cyclic sweep voltammetry was carried out using an electrol...

Herein we have deposited the Cadmium sulphide thin films chemically on glass substrates using modified spray pyrolysis technique, at 300 °C. The thickness of the deposited film was found to be 301 nm and the film was yellow in colour. Deposited CdS films were subjected to elemental, morphologic...
