TL;DR: In this article, a novel and scalable synthetic route to ATO thin films that shows excellent electrical properties was presented, which is an excellent candidate but is limited by its opto-electrical properties.
Abstract: Transparent conducting oxides have widespread application in modern society but there is a need to move away from the current ‘industry champion’ tin doped indium oxide (In2O3:Sn) due to high costs. Antimony doped tin(IV) oxide (ATO) is an excellent candidate but is limited by its opto-electrical properties. Here, we present a novel and scalable synthetic route to ATO thin films that shows excellent electrical properties. Resistivity measurements showed that at 4 at% doping the lowest value of 4.7 × 10−4 Ω cm was achieved primarily due to a high charge carrier density of 1.2 × 1021 cm−3. Further doping induced an increase in resistivity due to a decrease in both the carrier density and mobility. Ab initio hybrid density functional theory (DFT) calculations show the thermodynamic basis for the tail off of performance beyond a certain doping level, and the appearance of Sb(III) within the doped thin films.

TL;DR: In this article, the spectral interferences of phosphorus species originating from the thermal decomposition of calcium phosphate on Sb, As, Se and Te resonance lines, and the influence of increasing amounts of Ce, Ni, W, Pd, Pt, Zr and other elements on non-correctable signals generated by calcium phosphate and on selenium and phosphorus sensitivity have been studied.

TL;DR: In this paper, simultaneous adsorptive stripping voltammetric (AdSV) determination of the four elements molybdenum, antimony, vanadium, and uranium as their chloranilic acid (2,5-dichloro-4,6-dihydroxy-1,3-benzoquinone) complexes is described, the parameters of the procedure were varied to produce the best peak resolution with regard to the sensitivity.

TL;DR: In this paper, a three-dimensional macroporous antimony@carbon composite (Sb@C-3DP) is fabricated by a simple KCl template method with a single bi-functional precursor potassium antimony tartrate.
Abstract: Potassium-ion batteries (KIBs) are considered important substitutes for lithium-ion batteries (LIBs) owing to the abundance of K resources. Herein, a novel three-dimensional macroporous antimony@carbon composite (Sb@C-3DP) is fabricated by a simple KCl template method with a single bi-functional precursor potassium antimony tartrate. The Sb@C-3DP electrode delivers an excellent rate capability (286 mA h g−1 at 1 A g−1) and remarkable reversible capacity (516 mA h g−1 at a low current density of 0.05 A g−1). Moreover, an outstanding long-term cycling stability (97% capacity retention after 260 cycles) is also achieved, which is benefited from the unique microstructure that can accommodate the huge volumetric change of Sb during depotassiation and potassiation processes. A full cell constructed by coupling Sb@C-3DP with a Prussian blue cathode exhibits a high energy density (197.6 W h kg−1) and power density (2067.9 W kg−1).
