Delocalized Electronic Buffering at Pd/High-Entropy Oxide Interfaces Enables Water-Tolerant Methane Oxidation

Abstract Developing Pd-based catalysts for methane oxidation that combine low-temperature activity with strong water tolerance remains a major challenge for emission control applications. Herein, we introduce a high-entropy architecture into Co3O4-based spinel supports to regulat...

Mechanism and Origins of Enantioselectivity of Rhodium‐Catalyzed [4+3] Annulation of Benzosilacyclobutenes with 7‐Oxabenzonorbornadienes

ABSTRACT Rhodium‐catalyzed asymmetric [4+3] annulation of benzosilacyclobutenes with 7‐oxabenzonorbornadienes provides an efficient route to enantioenriched seven‐membered sila‐heterocycles. In this study, density functional theory calculations were performed to elucidate the rea...

Research on cross-industry production based on system dynamics under major emergencies

Purpose This study aims to investigate how supply chain disruptions caused by major public emergencies, such as geopolitical conflicts, affect firm performance and examines whether cross-industry production (CIP) can mitigate losses by repurposing capacity to produce contingency...

LiCoO 2 /LiMn 0.6 Fe 0.4 PO 4 Composite Cathode with Enhanced Interfacial Structure Enables Long‐Life Lithium‐Ion Batteries

ABSTRACT Extending the cycle life of LiCoO 2 (LCO) cathodes under elevated cutoff voltages remains a critical challenge for lithium‐ion batteries, as accelerated degradation is often governed by reaction heterogeneity and interfacial instability. Herein, we report a composite cat...

Modal degeneracy and oblique bending modes in ultra-long cable-strut deployable space masts

With the increasing application of large-scale ultra-long space deployable structures in aerospace engineering, low-order modal degeneracy and the resulting oblique bending modes have become critical issues affecting structural dynamic performance and on-orbit stability. This pap...

N-Terminal Basic Helix and S120 Phosphorylation Cooperatively Regulate Nuclear Localization of UBE2A/B in Mechanotransduction

Cells are continuously exposed to mechanical stimuli arising from the extracellular matrix, neighboring cells, and tissue architecture. Through mechanotransduction, these physical cues are converted into intracellular signaling events that regulate cellular behavior and fate. In...

Identification and compensation of geometric parameter errors for Non-Orthogonal shafting laser coordinate measuring instrument

With the deepening research in the field of large-scale coordinate measurement, non-orthogonal shafting 3D laser coordinate measuring instruments provide new possibilities for high-precision measurement in complex scenarios due to their advantages such as compact structure and st...

Association between low-level geometric features of central gaze-guiding patterns and SSVEP responses in mixed reality head-mounted display environments

This study investigated the correlation between the low-order geometric properties of centrally fixated guide patterns and steady-state visual evoked potential (SSVEP) responses in a mixed reality (MR) head-mounted display environment. An MR-SSVEP experimental environment was est...

Energy storage for a flexible and decarbonized power system in China: Pathways and regional deployment

The power system transition is central to achieving China's dual‑carbon targets of carbon peaking by 2030 and carbon neutrality by 2060. The rapid expansion of variable renewable energy (VRE) has made pumped hydro storage (PHS) and battery energy storage systems (BESS) critical f...

Bisphenol A and Its Substitutes Bisphenol S/Bisphenol F in Combined Exposure Collectively Exacerbate Hepatotoxicity by Triggering Oxidative Stress and Inflammatory Responses via the PI3K-Akt/NF-κB Axis

Abstract Bisphenol A (BPA) and its substitutes bisphenol S (BPS) and bisphenol F (BPF) are environmental endocrine-disrupting chemicals that frequently co-occur. However, the hepatotoxic effects and underlying mechanisms of their combined exposure remain unclear. This study integ...

A knowledge-augmented diffusion framework for generating regionally distinctive architectural facades: a case study of Huizhou dwellings

Abstract Generating heritage facade images with recognizable regional style is increasingly feasible with diffusion models, but prompt engineering or standard fine-tuning alone rarely encodes the construction logic, spatial hierarchy, and symbolic rules that make such heritage ar...
