The objective of this work was to provide updated information on the development of the potential impact of heavy metal containing batteries on municipal waste and battery recycling processes following transposition of the new EU Batteries Directive 2006/66/EC. A representative sample of 146 dif...

Hydrogen sulfide (H2S) and some functional amino acids in crops have been involved in the defense system against heavy-metal pollution. Here we report the relationships and functions of H2S and proline to cadmium (Cd) stress. Sodium hydrosulfide (NaHS) pretreatment decreased the electrolytic lea...

With the biomolecule glutathione (GSH) as a capping ligand, Eu3+-doped cadmium sulfide composite nanoparticles were successfully synthesized through a straightforward one-pot process. An efficient fluorescence energy transfer system with CdS nanoparticles as energy donor and Eu3+ ions as energy ...

Reaction of metal chlorides (MCl2) with tripiperidinophosphine chalcogenides (Pip3PE) produces new dimer species (1–6) of the formula [MCl2(Pip3PE)]2 (Pip = piperidinyl; E = S or Se; M = Hg, Cd or Zn). These coordination complexes were characterized by elemental analysis, IR, multinuclear (31P,...

Cadmium (Cd) is a non-essential trace element that is widely distributed in the environment. Both geogenic and anthropogenic sources can elevate Cd concentrations in soils and groundwater, which are important for maintaining healthy supplies of food and safe drinking water. Elevated Cd doses are...

Novel lanthanum ion-doped cadmium sulfide quantum dots (CdS:La QDs) were synthesized and characterized by transmission electron microscopy (TEM) and photoluminescence (PL). Based on CdS:La QDs as the electrochemiluminescence (ECL) luminophores, a distance-dependent ECL intensity enhanced or quen...

The phase transition and thermal equation of state of cadmium sulfide (CdS) were studied at high pressure and temperature conditions up to 21.9 GPa and 650 K, by using in situ synchrotron angle-dispersive X-ray diffraction and an externally-heated diamond anvil cell (DAC). A pressure-induced pha...

Nanorods of bismuth sulphide were prepared by thermal decomposition of bismuth N-ethyl cyclohexyl dithiocarbamate at different calcination duration. X-ray diffraction (XRD) analysis shows that at 400 °C, the precursor was fully decomposed to orthorhombic bismuth sulphide after 2 h of calcinatio...

The integration of photothermal therapy (PTT) with photodynamic therapy (PDT) has great potential to revolutionize conventional therapeutic approaches for cancers. However, most of the currently developed nanoplatforms for combinatorial phototherapy require the participation of different compone...

High dielectric composites of bismuth sulfide (Bi2S3) filled in poly (vinyl alcohol) (PVA)/polypyrrole (PPy) blend were prepared. Fourier Transform Infrared Spectroscopic analysis infers the encapsulation of Bi2S3 particles by PVA: PPy matrix. The thermal activation is estimated using Coats and ...

The preparation of rod-like bismuth sulfide structures, effectively anchored to graphene oxide (GO) sheets, is informed using a fast and trouble-free method. This strategy, which incorporates elemental sulfur as S2− source, hot dimethylsulfoxide as solvent, and a short reaction time, has been us...

Ultra-fine, highly dispersed bismuth sulfide nanoparticles have been synthesized, using two different sulphur sources (sodium sulfide and thiourea) by applying a wet chemical method. The bismuth sulfide (BST) nanoparticles synthesized using thiourea, as a sulphur source, displayed higher crystal...

Copper antimony sulfide (CAS) has been proposed as low toxicity and earth abundant absorber materials for thin film photovoltaics due to their suitable optical band gap, high absorption coefficient and p-type electrical conductivity. The present work reports the formation of copper antimony sulf...

Selective dissolution of stibnite from a complex sulfidic antimony ore containing pyrite by ozonation leaching in hydrochloric acid solution has been studied in the paper. Effects of hydrochloric acid concentration, leaching time, temperature, gas (ozone and oxygen mixture) flow rate and liquid/...

In copper metallurgy, antimony impurities usually form alloys and compounds with the transition metals to make up the basic building blocks of a speiss phase. This speiss phase is generally rich in copper and precious metals, which are desirable to recycle and recover at the smelter. The presenc...
