Integrated ultrasensitive metabolomics and single-cell transcriptomics identify crucial regulators of sheep oocyte maturation and early embryo development in vitro.

Introduction: Developmental competence of oocytes matured in vitro is limited due to a lack of complete understanding of metabolism and metabolic gene expression during oocyte maturation and embryo development. Conventional metabolic analysis requires a large number of samples and is not efficiently applicable in oocytes and early embryos, thereby posing challenges in identifying key metabolites and regulating their in vitro culture system.

Objectives: To enhance the developmental competence of sheep oocytes, this study aimed to identify and supplement essential metabolites that were deficient in the culture systems.

Lead-free Perovskite with Distorted [InX] Octahedron Induced by Organic Cation and Enhanced PLQY by Sb Doping.

In-based halide perovskites have attracted a lot of attention because of their unique broadband emission properties. Herein, a series of In-based hybrid perovskites of (HMP)InCl·HO (), (HEP)InCl·HO (), (HMP)InBr·HO (), and (HEP)InBr·HO () were synthesized under the control of halogen ions and organic cations. , , and exhibit obvious photoluminescence properties with peaks at 392, 442, and 652 nm, respectively.

Seeking environmentally friendly halide perovskite photocatalysts: synthesis, structure and photocatalytic performance exploration.

Halide perovskites have high photoelectric conversion efficiency, making them promising candidates for photocatalysis. However, their toxic and unstable nature limits their applications. Here, we successfully synthesised three hybrid Bi-based halide perovskites: (HTMG)BiBr (1), (HEI)BiBr (2) and (HTMA)BiBr (3).

Structural Regulation and Oxygen Reduction Reaction Activity of [Co(bpy)BO(OH)] and [Cu(bpy)(OH)] Complex Templated Borates.

Two templated borates, [Co(bpy)BO(OH)]·[BO(OH)]·HBO·HO·HO () and [Cu(bpy)(OH)]·[BO(OH)]·HO (), have been synthesized successfully and characterized by single-crystal X-ray diffraction, powder X-ray diffraction, and Fourier transform infrared. The [Co(bpy)BO(OH)] complex in shows a very rare coordination mode between Co and BO(OH). The structures of and can be adjusted by changing the reagent.
