TL;DR: In this paper, the effects of Sb(III and V) on the growth and yield of rice, and the antimony concentration in rice tissue were investigated in seed germination and pot experiments for rice.

TL;DR: In this article, the carrier concentration, optical mobility, and resistivity of post-annealed antimony doped tin oxide (ATO) thin films were analyzed using the Drude model.

TL;DR: Although previous studies concluded that As(V) is more effectively removed than As(III), this study showed that the removal of Sb(III) by coagulation with FC was much more pronounced than that of SB(V); oxidation of S b( III) with chlorine decreased the ability of FC to remove antimony.

TL;DR: The current understanding of antimony biochemistry and biogeochemistry is roughly equivalent to where that of arsenic was some 20 years ago, indicating the possibility of future discoveries with regard to the ability of microorganisms to conserve energy for their growth from antimony redox reactions and the isolation of new species of “antimonotrophs.”
Abstract: Antimony (Sb) is a toxic metalloid that occurs widely at trace concentrations in soil, aquatic systems, and the atmosphere. Nowadays, with the development of its new industrial applications and the corresponding expansion of antimony mining activities, the phenomenon of antimony pollution has become an increasingly serious concern. In recent years, research interest in Sb has been growing and reflects a fundamental scientific concern regarding Sb in the environment. In this review, we summarize the recent research on bacterial antimony transformations, especially those regarding antimony uptake, efflux, antimonite oxidation, and antimonate reduction. We conclude that our current understanding of antimony biochemistry and biogeochemistry is roughly equivalent to where that of arsenic was some 20 years ago. This portends the possibility of future discoveries with regard to the ability of microorganisms to conserve energy for their growth from antimony redox reactions and the isolation of new species of "antimonotrophs."

TL;DR: In this paper, the authors studied the mechanism of the reaction with lithium in the negative electrode of Li-ion cells and found that the first discharge involves the irreversible decomposition of the solid to non-crystalline cobalt and Li-ClOI alloy.
