Hydrogen-Bonding-Guided Molecular Pair Suppresses Self-Aggregation for Uniform Passivation of Efficient Inverted Perovskite Solar Cells

Abstract Surface passivation is critical for high-performance perovskite solar cells (PSCs), yet achieving a uniform molecular layer is hindered by uncontrolled molecular aggregation, thereby limiting passivation efficiency. Here, we introduce an aggregation control strategy usin...

A Standardized Chewable Conductive Hydrogel Sensor for Direct Monitoring of Masticatory Dynamics

ABSTRACT Chewing is a fundamental orofacial function closely related to nutrition, digestion, and quality of life, yet current assessment methods generally rely on indirect signals or endpoint measurements and provide limited process‐level information. Here, a hydroxypropyl cellu...

Stable truncating mutations in plakophilin-2 induce arrhythmogenic cardiomyopathy-like phenotypes in adult zebrafish

Arrhythmogenic cardiomyopathy (ACM) is an inherited cardiac disorder characterized by arrhythmias and fibrofatty myocardial remodeling, often leading to heart failure and sudden cardiac death. Mutations in plakophilin-2 ( PKP2 ) represent the most prevalent genetic cause of ACM....

Unilateral Functionalization of Covalent Organic Frameworks: Local Electronic Modulation and Morphology-Enabled Mass Transport for Electrocatalytic Hydrogen Peroxide Production

Abstract Achieving high selectivity and activity in the two-electron oxygen reduction reaction (2e– ORR) pathway critically depends on the synergistic modulation of a catalyst’s electronic structure and mass diffusion channels. This work proposes an asymmetric modulation strategy...

Bridging, Destabilisation, and Simulacrality: The Visual Rhetoric of Travel-Related Live Images on Xiaohongshu

As a visual form on contemporary social media platforms, Live Images transform the photographic instant into a short dynamic event through micro‑temporal extension and looped playback. When applied to travel imagery, this format doesn’t simply preserve a frozen scene, but foregro...

High-temperature mechanical properties of basalt fiber-reinforced concrete after salt spray erosion

To investigate the durability performance of basalt fiber-reinforced concrete (BFRC) subjected to the coupled effects of salt spray erosion and fire-induced high temperatures, this study systematically conducted combined exposure tests with salt spray durations (0, 30, 90, and 18...

GaN nanorods/N–doped carbon derived from Ga–MIL–68 as a separator coating for suppressing the shuttle effect in lithium–sulfur batteries

Lithium–sulfur batteries (LSBs) offer high theoretical energy density, yet their practical deployment is constrained by lithium polysulfide (LiPS) shuttling, sluggish sulfur redox kinetics, and unstable lithium deposition. This work addresses whether a single separator coating ca...

Establishing CT-number-to-electron/density curves for hypersight CBCT with a standard cirs 062 M phantom: a methodological comparison of three practical approaches

HyperSight cone-beam computed tomography (CBCT) with Acuros reconstruction is reported to enable direct dose calculation in adaptive radiotherapy, but its accuracy depends on a reliable CT-number-to-electron/material-density (CT-ED/MD) calibration curve.The CT-number-to-material-...

Study on the Crosslinking of Glycerol Triglycidyl Ether and Lyocell Based on Molecular Dynamics Simulations and Its Anti-Fibrillation Performance: from Simulation to Experiment

Abstract Lyocell is a regenerated cellulose fiber with high potential for sustainable textile applications, but its fibrillation remains a major limitation. Crosslinking can suppress fibrillation by constructing a network structure. However, its molecular-level behavior remains u...

Effect of Nano‐CeO 2 Powder on Microstructure and Wear Resistance of Deloro 40 Coating Prepared by Laser Additive Manufacturing

In this study, a series of Deloro40 + x CeO 2 ( x = 0, 0.5, 1, 2, and 5 wt%) coatings were fabricated on SS316L stainless steel by laser additive manufacturing. The microstructure evolution, mechanical properties, and tribological behaviors of the deposited coatings were systemat...

Frequency-decoupled dynamic graph learning with degradation prior for robust state-of-health estimation of lithium-ion batteries

State-of-health (SOH) estimation of lithium-ion batteries is critical for reliable battery management in energy storage systems, where SOH must be inferred from noisy multi-frequency health indicators under varying operating conditions. Existing methods often fail to decouple mul...
