Manipulating the electronic environment of the reactive center to lower the energy barrier of the rate-determining water oxidation step for boosting the direct generation of HO from water, air, and sunlight is fascinating yet remains a grand challenge. Driven by a first-principles screening across a series of metal single atoms in carbon nitride, we report a class of an Al-N bridge site enabling interlayer charge transfer in carbon nitride nanotubes (CNNT-Al) for the highly efficient photosynthesis of HO directly from water, oxygen, and sunlight. We demonstrate that the interlayered Al-N bridge site in CNNT-Al is able to activate the neighboring surface N atom for promoting the rate-determining step of the two-electron water oxidation to HO.

Curr Pharm Biotechnol

October 2024

Metabolic Syndrome (MetS) refers to the co-occurrence of a constellation of metabolic diseases in the same individual, such as abdominal/visceral obesity, insulin resistance or diabetes, alterations in the lipid profile (dyslipidemias), and/or hypertension, which promotes the development of other cardiometabolic and hepatic diseases. Dyslipidemia and metabolic dysfunction- associated steatotic liver disease (MASLD), previously termed nonalcoholic fatty liver disease (NAFLD), are common MetS pathologies closely related to lipid metabolism. Alterations in the metabolism of proteins, carbohydrates, and lipids, caused by an excessive intake of nutrients and abnormal accumulation of body fat, which promotes chronic low-grade inflammation, are pivotal aspects of MetS development.

Laboratory of Cell Biology, Department of Microscopy, ICBAS-Instituto de Ciências Biomédicas Abel Salazar, Universidade Do Porto, Rua Jorge Viterbo Ferreira, 228, 4050-313, Porto, Portugal.

The ultrastructure of human oocytes has been described only qualitatively. To offer a precise organelle spatial distribution and organelle volume during the main maturation stages, we previously conducted stereological studies on prophase-I (GV) and metaphase-I (MI) oocytes, and here we present results on metaphase-II (MII) oocytes. Five donor oocytes from different donors were processed for transmission electron microscopy, and quantification of organelle distribution was performed using point-counting stereology.

National Laboratory of Solid State Microstructures, Jiangsu Key Laboratory of Artificial Functional Materials, College of Engineering and Applied Sciences, Nanjing University, Nanjing, P. R. China.

Van der Waals integration of freestanding perovskite-oxide membranes with two-dimensional semiconductors has emerged as a promising strategy for developing high-performance electronics, such as field-effect transistors. In these innovative field-effect transistors, the oxide membranes have primarily functioned as dielectric layers, yet their great potential for structural tunability remains largely untapped. Free of epitaxial constraints by the substrate, these freestanding membranes exhibit remarkable structural tunability, providing a unique material system to achieve huge strain gradients and pronounced flexoelectric effects.

October 2024

Optogenetics & Synthetic Biology Interdisciplinary Research Center, State Key Laboratory of Bioreactor Engineering, East China University of Science and Technology, 130 Mei Long Road, Shanghai, 200237, China.

Fluorescent RNAs (FRs), which are RNA aptamers that bind and activate their cognate small fluorogenic dyes, have provided a particularly useful approach for imaging RNAs in live cells. Although the color palette of FRs is greatly expanded, a bright and stable cyan FR with good biocompatibility and biorthogonality with currently available FRs remains desirable but is not yet developed. Herein, the development of Myosotis is described, an RNA aptamer that emits bright cyan fluorescence upon binding a novel GFP chromophore-like fluorophore called DBT.
