TL;DR: In this paper, Antimony doped tin oxide thin films were deposited on glass substrates by sol-gel dip coating technique and optical properties of the films have been studied from transmission spectra.

TL;DR: It is suggested that antimony affects nitrogen cycle in soil by changing urease activity under the neutral pH, however, soil enzyme activities may not be a good protocol due to their complex response patterns to antimony pollution.

TL;DR: A rapid and scalable microwave synthesis of one-dimensional nanocrystals of sulfurized antimony selenide that exhibit 10(4)-10(10) times higher electrical conductivity than non-nanostructured bulk or thin film forms of this material.
Abstract: Antimony selenide is a promising thermoelectric material with a high Seebeck coefficient, but its figure of merit is limited by its low electrical conductivity. Here, we report a rapid and scalable (gram-a-minute) microwave synthesis of one-dimensional nanocrystals of sulfurized antimony selenide that exhibit ∼104−1010 times higher electrical conductivity than non-nanostructured bulk or thin film forms of this material. As the nanocrystal diameter increases, the nanowires transform into nanotubes through void formation and coalescence driven by axial rejection of sulfur incorporated into the nanowires from the surfactant used in our synthesis. Individual nanowires and nanotubes exhibit a charge carrier transport activation-energy of ∼<60 meV arising from surface sulfur donor states. Nanocrystal assemblies also show high electrical conductivity, making the nanocrystals attractive building blocks to realize nanostructured thin film and bulk forms of this material for thermoelectric device applications.

TL;DR: The results suggest that gibbsite will likely play an important role in immobilizing Sb (V) in the soil environment, possibly via inner-sphere type mechanism with the formation of a binuclear monodentate surface complex.

TL;DR: Antimony film electrodes (SbFEs) as mentioned in this paper offer some interesting characteristics such as favorably negative overvoltage of hydrogen evolution, wide operational potential window, convenient operation in acidic solutions of pH 2 or lower and a small Sb stripping signal.
Abstract: This review summarizes analytical determinations carried out using antimony film electrodes (SbFEs), an environmentally safe option that constitutes an alternative not only to the most conventional Hg-based electrodes but also to Bi-based electrodes. SbFEs offer some interesting characteristics such as favorably negative overvoltage of hydrogen evolution, wide operational potential window, convenient operation in acidic solutions of pH 2 or lower and a very small Sb stripping signal. The substrate on which the Sb was plated is used to classify the types of SbFEs. Moreover, we detail the method of coating the substrate with Sb as well as the Sb modifiers. We present tables with the most important information from the accessible literature.
