Isolated p-Block Antimony Atoms Activated CuO@Co-CN Enable High Performances for Water Splitting and Zn-Air Batteries.

This study reports an effective strategy for designing 3D electrocatalyst via the deposition of ZIF67-derived Co-CN shell layer over CuO nanoarrays to form a CuO@Co-CN hybrid, followed by incorporation with p-block Sb single atoms (CuO@Co-CN/Sb) to obtain highly activated catalytic behaviors. Inheriting both the excellent intrinsic catalytic activity of the components and their synergy, the CuO@Co-CN/Sb material serves as a high-efficiency multifunctional catalyst for overall water splitting and zinc (Zn)-air batteries. The material yields a current density of 10 mA cm at a low overpotential of 72 and 250 mV for the hydrogen evolution reaction and oxygen evolution reaction, respectively.

Impact of dietary exposure to polyester microfibers on hematology, serology and histology in a mouse model.

Synthetic fabrics, especially polyester, are a primary source of microplastic fibers (MFs), but there is limited data on their accumulation and dose related health impact in living organisms. This study examined the effects of ingested polyester microfibers (PE-MFs) on hematology, histopathology, and serum biochemistry in albino mice. Mice were given varying doses of PE-MFs (100, 200, 400 and 800 μg/d/mice) for a duration of thirty-five days and a notable decreases in certain hematological parameters such as RBCs, Hb, and platelets, and increases in MCV and MCH was noted at (p < 0.

Manganese-Doped Bimetallic (Co,Ni)P Integrated CoP in N,S Co-Doped Carbon: Unveiling a Compatible Hybrid Electrocatalyst for Overall Water Splitting.

Rational design of highly efficient noble-metal-unbound electrodes for hydrogen and oxygen production at increased current density is crucial for robust water-splitting. A facile hydrothermal and room-temperature aging method is presented, followed by chemical vapor deposition (CVD), to create a self-sacrificed hybrid heterostructure electrocatalyst. This hybrid material, (Mn-(Co,Ni)P/CoP/(N,S)-C), comprises manganese-doped cobalt nickel phosphide (Mn-(Co,Ni)P) nanofeathers and cobalt phosphide (CoP) nanocubes embedded in a nitrogen and sulfur co-doped carbon matrix (N,S)-C on nickel foam.
