Highly Tunable Schottky Barrier to 2D Semiconductors Enabled by an Inorganic‐Molecular‐Crystal Tunneling Layer

ABSTRACT Effective tuning of the Schottky barrier, which determines charge transport across the metal‐semiconductor interface, is essential for optimizing the performance of electronics and optoelectronic devices. However, interfacial disorders and orbital overlap between metals...

A CRISPR-based ‘dam-break drainage’ sensing architecture for rapid, affordable and ultrasensitive pathogen detection

Abstract Nucleic acid testing is important for infectious-disease diagnosis, but combining high sensitivity with accessible testing remains challenging. Here we show a chip-based visual detection strategy for one or two viral RNA targets that involves only sample loading, without...

A closed-loop authentication-detection security framework for edge computing environments integrating trusted computing and distilled pre-trained language models

Edge computing environments hosting tens of thousands of nodes face concurrent threats including node spoofing, data tampering, and distributed denial-of-service attacks, yet existing security solutions address authentication, intrusion detection, and resource scheduling in isola...

Long-memory and cyclical link prediction in temporal social networks

<title>Abstract</title> Temporal social networks contain persistent tie activation and periodic communication rhythms, but most link prediction models either emphasize short-term recurrence or rely on black-box embeddings that offer no interpretable summary of temporal structure....

Modelling and multi-objective scheduling of an energy-efficient hybrid flow shop with multiple heating-forging cycles

This study addresses the characteristics of forging production scheduling and investigates an energy-efficient hybrid flow shop scheduling problem considering multiple heating-forging cycles (EEHFSP-MHFC). The problem is formulated as a multi-objective optimisation problem with t...

Engineering Hidden Ferroelectric‐Like Distortion for Ultralow Thermal Conductivity in Polar van der Waals Tetradymite

ABSTRACT Ferroelectric‐like polar structures enable diverse functionalities through coupling with charge and phonon transport. Although effective in modulating thermal conductivity, the rational design of novel polar materials with intrinsically low thermal conductivity via ferro...

Chinese students’ L2 classroom engagement in college: Perceived teacher support, value beliefs and self-monitoring

<title>Abstract</title> Based on an integrated framework of the Self-Determination Theory and the Expectancy-Value Theory, this study investigated the link between students’ perceived teacher support and their L2 classroom engagement via two mediators: students’ value beliefs of...

Application of neural networks for predicting convective impact heat transfer coefficients in post-rolling steel plate cooling

The water jet impingement boiling heat transfer coefficient (HTC) during controlled cooling after rolling is a critical parameter governing microstructural evolution and temperature distribution in steel plates. Conventional experimental measurement and numerical simulation appro...

Attention-based time–frequency aggregated tokens for sound event classification in basketball game

Abstract With the rapid advancement of computer technology, its application in basketball game analysis has become a prominent research focus. Sound events in basketball games encapsulate critical game-related information. However, research on sound event classification in basket...

Towards Building a Multi-Source Heterogeneous Knowledge Graph for Complex Material Question Answering

Large Language Models (LLMs) show considerable potential for materials-science question answering. However, LLM responses may still be affected by unsupported parametric associations, while dense Retrieval-Augmented Generation (RAG) can fragment relational evidence across text ch...

A superelastic titanium alloy showing nearly temperature-independent high strength and elastic modulus

Lightweight superelastic alloys with temperature-insensitive properties are critical for deep-space exploration devices, yet their development is hindered by the challenge of simultaneously balancing strength, recoverable strain, and temperature sensitivity. Here, we overcome the...

Effect of Delivery Tube Diameter on Melt Breakup and Powder Refinement During Water Atomization of FeSiCr Alloy Powder

Water atomization is widely used for producing FeSiCr alloy powder, in which melt delivery conditions strongly influence jet breakup and powder refinement. In this study, a coupled volume of fluid-discrete phase model (VOF-DPM) was established to investigate the effect of deliver...

Short-term managerial focus and carbon disclosure strategy: behavioral agency evidence on government scrutiny and investor sentiment

Purpose This study aims to examine how managerial myopia shapes corporate carbon disclosure strategy and whether myopic managers rely mainly on symbolic rather than substantive disclosure. Design/methodology/approach Using panel data on Chinese central state-owned enterprises in...

Experimental study on the deflagration and flame‐development characteristics of hydrogen‐blended natural gas flames under various initial conditions

Abstract Hydrogen‐blended natural gas (HBNG) is an effective transitional solution for large‐scale hydrogen energy transportation, whose safety requires quantitative assessment from a practical perspective. This study constructed a 60 L cylindrical deflagration experimental setup...

Influence of Interruptions on the Diagnosis Task Performance

ABSTRACT Digital nuclear power systems increasingly expose main control room (MCR) operators to multitasking and interruptions that disrupt cognitive resource allocation and threaten safety, yet the underlying mechanisms remain underexplored. This study conducted behavioral exper...

Stress-State-Dependent Reinforcement of Cement-Stabilized Soil Using Waste Brick Powder and Glass Fiber

Cement-stabilized soil is widely used for ground improvement but suffers from brittleness and low tensile strength. This study investigates combined modification of cement-stabilized soil with waste brick powder (WBP, 5%) and glass fiber (GF, 0–2.0%) to enhance mechanical perform...

Natural attenuation of p-nitrophenol in soil: kinetics, microbial dynamics, and functional gene responses
