α-Methyl Group Reinforced Amphiphilic Poly (ionic liquid) Additive for High-Performance Zinc-Iodine Batteries.

Aqueous zinc-iodine (Zn-I2) batteries are prospective on energy storage, yet the practical application is severely hindered by side reactions of Zn metal and the shuttle effects for polyiodide. Herein, a polymer additive PVEMA was copolymerized by 1-vinyl-3-ethylimidazolium trifluoromethanesulfonate (VEImOTf) and methacrylamide (MAAm) to alleviate the above issues. The polymer chain of PVEMA endows amphipathic properties for Zn2+ diffusion and solvation structure regulation, and the α-methyl of MAAm enhances the hydrophobic properties to avoid side reactions on Zn metal.

Analysis of Chemical Composition of Long-Chain Linear Alkylbenzenes Using High-Performance Liquid Chromatography Coupled with Microwave Plasma Torch Mass Spectrometry.

Long-chain linear alkylbenzenes (LABs) are essential precursors to produce alkylbenzene sulfonates, which have high surfactant properties and are readily biodegradable, widely used in various detergents. However, an effective and rapid method for the direct analysis and quality control of LAB chemical composition still needs to be improved. This study uses high-performance liquid chromatography coupled with microwave plasma torch mass spectrometry (HPLC-MPT-MS) to analyze the composition of long-chain LABs and quantify nine of these components.

The DnaJ1 heat shock protein interacts with the flavanone 3-hydroxylase-like protein F3HL to synergistically enhance drought tolerance by scavenging reactive oxygen species in tomato.

The widely distributed heat shock protein DnaJ is renowned for its pivotal role in enhancing thermal tolerance in plants; however, its involvement in drought tolerance remains elusive. In this study, genes encoding DnaJ1 were cloned from drought-resistant wild tomato (Solanum pennellii) and drought-sensitive cultivated tomato (Solanum lycopersicum). SpDnaJ1 and SlDnaJ1 from both tomato species were localized in the chloroplast, and their gene expression was induced by various abiotic stresses.

Unlocking the therapeutic potential of tumor-derived EVs in ischemia-reperfusion: a breakthrough perspective from glioma and stroke.

Clinical studies have revealed a bidirectional relationship between glioma and ischemic stroke, with evidence of spatial overlap between the two conditions. This connection arises from significant similarities in their pathological processes, including the regulation of cellular metabolism, inflammation, coagulation, hypoxia, angiogenesis, and neural repair, all of which involve common biological factors. A significant shared feature of both diseases is the crucial role of extracellular vesicles (EVs) in mediating intercellular communication.

VM-UNet++ research on crack image segmentation based on improved VM-UNet.

Cracks are common defects in physical structures, and if not detected and addressed in a timely manner, they can pose a severe threat to the overall safety of the structure. In recent years, with advancements in deep learning, particularly the widespread use of Convolutional Neural Networks (CNNs) and Transformers, significant breakthroughs have been made in the field of crack detection. However, CNNs still face limitations in capturing global information due to their local receptive fields when processing images.
