Herein, Sn nanoparticles supported on N-doped carbon (Sn/NC) were constructed by a g-CN assisted strategy for the interface layer of Zn anodes in Zn-ion batteries. The presence of Sn/NC effectively regulates the zinc plating/stripping process, which makes Sn/NC@Zn outstanding in both symmetrical and full cells.

Brazil, one of the world's largest agricultural producers and consumers of pesticides, has expanded its agricultural area in the southern region of Mato Grosso do Sul, intensifying environmental contamination and increasing the vulnerability of indigenous populations. This research assessed the presence of pesticides in the waters of two indigenous communities in MS, Retomada Guyraroká and Aldeia Jaguapiru. Between 2021 and 2022, three sampling campaigns of surface, supply, and rainwater were conducted, considering the agricultural calendar.

Introduction: Potassium bromate (KBrO) is an oxidizing agent added to flour to improve bread quality. However, KBrO is nephrotoxic, and a class B carcinogen banned in most countries, including Ghana.
Aim: This study aimed to determine the residual KBrO concentration in bread and to estimate the chemical and carcinogenic risk that is associated with the consumption of these breads in Ghana.

Aim: Foreign body ingestion, particularly that of magnets, is a significant issue for children aged 6 months to 3 years due to their prevalence in toys and household items. Most ingested foreign bodies pass naturally, but 10%-20% of such cases require endoscopic removal, and <1% require surgery.
Case Presentation: A 2-year-old girl presented with abdominal pain, nausea, and vomiting.

Doping with meclofenoxate, a nootropic stimulant prohibited in-competition by the World Anti-Doping Agency (WADA), is identified through the primary marker of urinary 4-chlorophenoxyacetic acid (4-CPA). However, the presence of 4-CPA can also arise from permissible sources. This study ventured into comparing urinary excretion patterns among exposures to permitted chemicals (chlorphenesin and 4-CPA) and the banned stimulant (meclofenoxate) and interpreting the analytical findings according to the reporting requirements.
