A Multifunctional Composite Interface Layer toward High-Performance Stable Zn Anode

The development of aqueous zinc-ion batteries (AZIBs) is often limited by uncontrolled dendrite growth and detrimental side reactions occurring at the Zn anode. Herein, a multifunctional protective coating, constructed by incorporating vermiculite nanosheets (VN) into a carboxyme...

Tuning spatial emission of 3D resonances in spiral nanomembrane microcavities by edge design

Spiral nanomembrane microcavities have shown notable flexibility in three-dimensional (3D) directional emission by predesigning the nanomembrane morphology prior to the rolling process. In this study, we demonstrate that the spatial emission of 3D optical resonances in spiral nan...

Single-nucleus transcriptomics uncovers region-specific molecular features underlying selective aging vulnerability of cholinergic neurons

Cholinergic neurons exhibit functional and molecular heterogeneity across the basal forebrain (BF), midbrain (MB), and brainstem (BS), while the aging-associated transcriptional features remain poorly characterized. Here, we performed single nucleus RNA sequencing (snRNA-seq) on...

A Compositional and Genetic Framework for Shale Lithofacies Classification and Reservoir Quality Prediction: Insights From the Wufeng‐Longmaxi Formation, South Sichuan

ABSTRACT Although shales are of fundamental importance in geological research and energy exploration, no consensus has been reached on a unified classification and nomenclature that adequately reflect their multiscale heterogeneity and genetic origins. To address this gap, we pro...

Forest Conversion Reduces Soil Water Retention in Tropical Rainforest

ABSTRACT Extensive primary forests are being converted to secondary forests and plantations owing to human activities in recent decades, which have substantial effects on soil hydrological processes. However, the potential impact of forest conversion on soil water retention remai...

On Z3-connectivity for graphs satisfying the Pósa-condition

Let G be a simple graph on n ≥ 3 vertices and π ( G ) = ( d 1 , … , d n ) be the degree sequence of G with d 1 ≤ ⋯ ≤ d n . If d j ≥ j + 1 for each j with 1 ≤ j < ⌈ n − 1 2 ⌉ and d j + 1 ≥ j + 1 for n to be odd and j = n − 1 2 , then G satisfies the Pósa-condition . Zhang and Yin...

Moral cognition and ethical perceptions in business: psychological insights from Gilgit-Baltistan’s cultural context

Abstract: This study examines the influence of ethical company practices, sustainability, and community involvement on consumer perceptions and the cultivation of trust. As demand for openness and accountability rises, consumers anticipate that firms will function in accordance w...

Preparation of salt-activated cementitious materials from high-temperature activated iron tailings and micromechanism

Abstract In this study, iron tailings were subjected to high-temperature activation at 600, 800, and 1 000 ℃, and then compounded with slag, cement, and sodium sulfate to prepare a salt‑activated cementitious material. The activation mechanism of the high-temperature activated ir...

Marker-Assisted Selection at VEQ2 Increases α-Tocopherol Content in Rice Grains Without Yield Penalty

Vitamin E is an essential dietary nutrient, yet deficiency affects large populations, especially in rice-dependent developing countries. To dissect the genetic basis of grain vitamin E content in rice, we performed a genome-wide association study (GWAS) on a diverse panel of 533...

Optimum stiffener spacing in stiffened hollow glulam beams based on particle swarm optimization

To optimize the mechanical performance of stiffened hollow glulam beams, this paper proposes a stiffener spacing optimization method based on the Particle Swarm Optimization algorithm. With the ratio of the beam's ultimate load-bearing capacity to its volume as the objective func...

Discovery of Symmetrical o ‐Methylpyridine Substituted Tertiary Amines and Dy(III) Complexes as Metallo‐β‐Lactamase Inhibitor and Antimicrobial

Due to the lack of metallo‐β‐lactamase (MβL) inhibitors for clinical purposes, the antibiotic resistance mediated by MβL poses a clear threat to public health. In this work, twelve symmetrical o ‐methylpyridine substituted tertiary amines P1 – P6 and their Dy(III) complexes D1 –...

Shear Stress-Triggered Piezo-Photocatalytic Thrombolysis, Self-Luminescent Thrombus Imaging, and Recurrence Prevention

Abstract Thrombotic diseases continue to pose substantial global harm, with high morbidity and mortality rates. Existing theranostic systems for thrombosis face significant risks such as bleeding complications, rapid clearance of therapeutic and imaging agents, and recurrence of...

Tensile stress–strain behavior and microstructure of PVA fiber‐reinforced geopolymer composites modified by nano‐ SiO 2

Abstract With the rapid development of green and low‐carbon construction materials, engineering geopolymer composites (EGCs), characterized by high strength, superior toughness, and excellent durability, have attracted increasing attention. However, achieving a synergistic enhanc...

Physics informed machine learning predicts binding free energy changes in protein-RNA complexes upon mutations

Protein-RNA interactions are central to gene regulation, yet predicting mutation-induced changes in binding free energy (ΔΔG) remains difficult due to sparse, heterogeneous measurements and strong imbalance in mutation types. Here we present Pred-MutPRI, a physics-informed machin...
