Radical Strategy towards N-glycosides: Current Advances and Future Prospects.

N-glycosides exhibit diverse biological and pharmacological activities, making their efficient synthesis crucial for both biological research and drug development. Traditional acid-promoted N-glycosylation methods, which rely on the formation of oxocarbenium intermediates, often face significant challenges. These methods are water-sensitive and typically require neighboring group participation to achieve high selectivity.

Cranial bone maneuver ameliorates Alzheimer's disease pathology via enhancing meningeal lymphatic drainage function.

Introduction: Alzheimer's disease (AD) is a progressive neurodegenerative disease and the leading cause of dementia. Recent research highlights meningeal lymphatics as key regulators in neurological diseases, suggesting that enhancing their drainage function could be a potential therapeutic strategy for AD. Our proof-of-concept study demonstrated that cranial bone transport can improve meningeal lymphatic drainage function and promote ischemic stroke recovery.

Breaking Aggregation State to Achieve Low-Temperature Fast Charging of Lithium Metal Batteries.

Insufficient ionic conductivity and elevated desolvation energy barrier of electrolytes limit the lithium metal batteries (LMBs) low-temperature applications. Weakly solvating electrolytes (WSEs), with limited lithium salt dissociation capability, are prone to desolvate and drive anion-rich aggregates (AGGs). However, significant AGGs result in increased viscosity and low ionic mobility, contributing to battery failure at low temperatures (≤ -20 oC).

Inhibiting Interfacial Electron Leakage via An Artificial Rectified Layer for Longevous Zinc Metal Anodes.

Dendrites and water-induced side reactions impose greatly challenge on the implementation of aqueous zinc ion batteries. To tackle these problems, an artificial rectified layer (ARL) with hydrophobic, zincophilic and insulating features was in-situ synthesized on Zn surface rapidly to prevent the electron leakage from Zn anode to aqueous electrolyte, which is the underlying logic for uneven Zn deposition and parasitic side reactions. The ARL also displays a high Zn2+ transference number of 0.

The electrochemical reduction of CO2 to high-energy-density hydrocarbons is pivotal for addressing energy and environmental challenges. Understanding the mechanisms underlying the conversion of CO2 to long-chain hydrocarbons is both crucial and complex. In this study, we employed density functional theory (DFT) calculations to investigate the C-C coupling mechanisms responsible for the formation of C2-C4 products on Pd3Au catalysts.

Rational Design of Cobalt-Based Prussian Blue Analogues via 3d Transition Metals Incorporation for Superior Na-Ion Storage.

Understanding the relationship between structure regulation and electrochemical performance is key to developing efficient and sustainable sodium-ion batteries (SIBs) materials. Herein, seven Cobalt-M-based (M=V, Mn, Fe, Co, Ni, Cu, Zn) Prussian blue analogues (CoM-PBAs) are designed as anodes for SIBs via a universal low-energy co-precipitation approach with the strategic inclusion of 3d transition metals. Density Functional Theory (DFT) simulation and experimental validation reveal that a moderate p-band center of cyanide linkages (-CN-) is more favorable for Na+ intercalation and diffusion, while the d-band center of metal cations is linearly related to electrode stability.

Light-Emitting Diodes Based on Metal Halide Perovskite and Perovskite Related Nanocrystals.

Taming the Ion-Dipole Interaction via Rational Diluent Selection for Low-Temperature Li-Metal Batteries.

Developing advanced electrolytes with high Li affinity is crucial for achieving long-cycling lithium metal batteries (LMBs). However, the strong Li+-solvent interactions in conventional electrolytes often induce difficult Li+ desolvation especially under low-temperature conditions, resulting in the formation of fragile electrode interfaces involving solvents, and thus dissatisfactory cycling stability of LMBs. Herein, by introducing various diluents into the lithium hexafluorophosphate in 1, 2-dimethoxyethane electrolyte, we reveal that Li+ desolvation is influenced by not only the diluent-solvent interaction but also the diluent-anion interaction.

The Critical Role of Atomic-Scale Polarization in Transition Metal Oxides on Vanadium-Redox Electrochemistry.

Transition metal oxide electrocatalysts (TMOEs) are poised to revive grid-scale all-vanadium redox flow batteries (VRFBs) due to their low-cost and unique electronic properties, while often inescapably harboring surface vacancies. The role of local vacancy-induced physicochemical properties on vanadium-redox electrochemistry (VRE), encompassing kinetics, and stability, remains profoundly unveiled. Herein, for the first time, it is revealed that vacancies induce atomic-scale polarization in TMOEs and elucidate its mechanism in VRE.

However, molecular mechanism underlying the negative regulation of soluble sugar accumulation in plants under salt stress conditions remains unknown.

Celastrol Ameliorates Hypoxia-Induced Pulmonary Hypertension by Regulation of the PDE5-cGMP-PKG Signaling Pathway.

Pulmonary hypertension (PH) is a severe pulmonary vascular disease characterized by poor clinical outcomes and limited therapeutic options. Celastrol (CEL), a natural product derived from Tripterygium wilfordii Hook F, has shown therapeutic potential in PH models, although its mechanisms are not fully understood. This study aims to investigate the role of CEL in PH and explore its potential underlying mechanisms.

Fluorescence of Aqueous Assemblies Regulated by Integral Water.

Water serves not only as a solvent but also as an integral component (interstitial water) in aqueous colloids self-assembled from POSS-NDI-POSS (POSS = polyhedral oligomeric silsesquioxanes, NDI = naphthalene diimide). The interstitial water confined within these colloids is attributed to the steric hindrance of the bulky POSS groups, which dissipates energy and quenches the fluorescence (FL). Control experiments with NDI molecules bearing less steric side groups (propyl or octyl), namely C3-NDI-C3 and C8-NDI-C8, confirm this role of water in structural assembly and optical function.

Colloidal Quantum-Dot Heterojunction Imagers for Room-Temperature Thermal Imaging.

Room-temperature operation or high-operation temperature (HOT) is essential for mid-wave infrared (MWIR) optoelectronics devices providing low-cost and compact systems for numerous applications.

Buckwheat UDP-Glycosyltransferase FtUGT71K6 and FtUGT71K7 Tandem Repeats Contribute to Drought Tolerance by Regulating Epicatechin Synthesis.

Glycosyltransferase genes are organised as tandem repeats in the buckwheat genome, yet the functional implications and evolutionary significance of duplicated genes remain largely unexplored. In this study, gene family analysis revealed that FtUGT71K6 and FtUGT71K7 are tandem repeats in the buckwheat genome. Moreover, GWAS results for epicatechin suggested that this tandem repeat function was associated with epicatechin content of Tartary buckwheat germplasm, highlighting variations in the promoter haplotypes of FtUGT71K7 influenced epicatechin levels.

The correlation between ANAs and pregnancy loss and their impact on IVF/ICSI-ET pregnancy outcomes in patients with recurrent pregnancy loss.

Objective: To explore the correlation between antinuclear antibodies (ANAs) and pregnancy loss (PL), and to observe its impact on the pregnancy outcomes of in vitro fertilization/intracytoplasmic sperm injection-embryo transfer (IVF/ICSI-ET) in recurrent PL (RPL) patients.

Methods: In this retrospective study, patients first seen at the hospital between January 2016 and December 2022 and who underwent two ANA tests within 4-6 weeks were included.
