TL;DR: The recent developments in antimony and bismuth-based chalcogenides electrode materials are summarized, including rational structural design strategies, electrochemical reaction mechanisms and the most recent advanced works.
Abstract: Sodium-ion batteries (SIBs) have received much attention, owing to their great potential for large-scale application. A lack of efficient anode materials with high reversible capacity is one main challenge facing the development of SIBs. Antimony- and bismuth-based chalcogenides materials can store large amounts of Na+ ions, owing to the alloying/dealloying reaction mechanism within a low potential range, and thus, are regarded as promising anodes for SIBs. However, these materials face great challenges of poor ion diffusion rate, multiple phase transformations, and severe morphology pulverization. Herein, recent developments in antimony- and bismuth-based chalcogenides materials, mainly rational structural design strategies used and the electrochemical reaction mechanisms involved, are summarized. Perspectives for further improving antimony- and bismuth-based chalcogenides anodes are also provided.

TL;DR: In this article, a solution growth process is employed for deposition of the pure and antimony-doped CdSe thin films with Sb 3+ doping concentration from 0.005 to 5.1% and the as-deposited films were found to be polycrystalline with the hexagonal wurtzite structure.

TL;DR: In this paper, X-ray powder diffraction (XRD) showed that the as-prepared nanorods were orthorhombic-phase Sb 2 S 3 with lattice parameters a =11.22, b = 11.28, and c = 3.84.

TL;DR: Atomic absorption spectroscopy has suggested that As- and Sb-containing species could be cotransported with GSH, and reduced intracellular accumulation of arsenic or antimony, reflecting an increased rate of arsenic efflux from the cells, is observed.
Abstract: Arsenic trioxide is an effective treatment for acute promyelocytic leukemia, but resistance to metalloid salts is found in humans. Using atomic absorption spectroscopy, we have measured the rate of uptake of arsenic trioxide and of antimony tartrate in GLC4 and GLC4/ADR cells overexpressing MRP1 and the rate of their MRP1-mediated effluxes as a function of the intracellular GSH concentration. In sensitive cells, after 1 h, a pseudosteady state is reached where intra- and extracellular concentrations of metalloid are the same. This precludes the formation, at short term, of complexes between arsenic or antimony with GSH. In resistant cells reduced intracellular accumulation of arsenic (or antimony), reflecting an increased rate of arsenic (or antimony) efflux from the cells, is observed. No efflux of the metalloid is observed in GSH depleted cells. The two metalloids and GSH are pumped out by MRP1 with the same efficiency. Moreover for the three compounds 50% of the efflux is inhibited by 2 μM MK571. This led us to suggest that As- and Sb-containing species could be cotransported with GSH.
