Summary: Sb/Sb2O3 micro-composites can be obtained through a simple electrochemical deposition process, with patterns containing regions rich in Sb and Sb2O3 emerging under specific conditions. The formation of these patterns is proposed to be a result of complex interactions between electrochemical Sb deposition, chemical Sb2O3 precipitation, and convection patterns near the electrode. These findings contribute to a better understanding of electrochemical metal/oxide co-deposition and can aid in the design of advanced composite coatings.

Summary: The study investigates the formation mechanism of Sb/Sb2O3 composites using electrochemical, chemical, electron microscopy, and X-ray diffraction methods. It is experimentally verified for the first time that electrodeposition of Sb causes a local pH shift leading to the co-deposition of Sb2O3. A nucleation and growth model is proposed based on the results to explain the development of different Sb/Sb2O3 structures and compositions.

Summary: Strain SVR, a dissimilatory antimonate-reducing bacterium, was isolated from soil and demonstrated the ability to reduce Sb(V) to precipitates. X-ray diffraction analysis revealed the precipitates to be Sb2O3, known as valentinite, with the bacterium able to form two different crystalline Sb2O3 structures under different pH conditions.

Summary: In this study, the evaporation process of antimony trioxide was investigated using nitrogen gas bubbling method at high temperatures, and it was found to be a second-order reaction. Increasing the temperature and gas flow rate while decreasing the lance height enhanced the evaporation rate and antimony recovery. The evaporated product was characterized and the residual slag was analyzed to understand the limitations of antimony trioxide evaporation.

Summary: Antimony trioxide dissolution is catalyzed by manganese and the oxidation of manganese plays a critical role in antimony release. The released antimony is partially retained on manganese oxides as bidentate-binuclear complexes. Valentinite exhibits higher activity in catalyzing manganese oxidation and faster dissolution compared to senarmontite.

Summary: The study found that food intake was the major pathway for both Sb and As exposure, with rice and vegetables being significant sources. Monte Carlo simulations showed that majority of residents exceeded the threshold dosages for Sb and As intake. Sb exhibited similar internal exposure characteristics as As, but the transfer rate from environment to human body was lower for Sb. Drinking water was identified as another important pathway with high bioavailability, especially for male residents. These findings provide important information on the exposure of Sb and As in typical Sb mining areas.

Summary: The study investigated the effects of loading different concentrations of heavy metal oxide Sb2O3 into a transparent glass system on the non-linear optical (NLO) and gamma radiation shielding properties of the glasses. The results showed an increase in two-photon absorption coefficient and changes in optical limiting threshold with increasing Sb2O3 substitution for B2O3. The linear attenuation coefficients also increased at 0.4111 MeV, indicating potential applications in laser and nuclear radiation protection glasses.

Summary: Metal phosphides are highly toxic pesticides that cause significant morbidity and mortality worldwide. This systematic review included 350 studies and found an increasing trend in cases of acute aluminum phosphide (AlP) and zinc phosphide (Zn3P2) poisoning, indicating a growing number of affected patients. AlP poisoning studies accounted for a large proportion of the included research and high mortality rates have fueled research interest in this area. Various therapeutic modalities have been explored, showing promising results in reducing mortality, but further meta-analyses are needed to establish their effectiveness. The article also highlights the need for an effective antidote and standardized protocol for managing acute AlP poisoning.

Summary: This systematic review and meta-analysis examined the effect of antioxidants on the outcome of acute aluminum phosphide poisoning. The results show that antioxidants significantly decrease mortality and the need for intubation and mechanical ventilation. N-Acetyl cysteine and vitamin E were particularly effective in reducing mortality. However, further trials and analyses are recommended to ensure the reliability of these findings.
