Tough Hydrogel-Mediated Constrained Assembly of Multidimensional Topological Networks for Synergistic Mechanical-Thermal Enhancement

Abstract The rapid development of high-power flexible electronics demands thermal management materials with both high thermal conductivity and mechanical robustness. However, traditional high-loading thermal management materials suffer from an intrinsic mechanical-thermal trade-o...

Assessing the Digital Leadership Preparedness for the AI Era: A Latent Profile Analysis Based on the ACC Model

Purpose This study investigates the digital leadership of Chinese K-12 educational administrators in the context of rapid artificial intelligence (AI) development. Design/Approach/Method Drawing on survey data from 1,426 educational administrators in Guangxi Zhuang Autonomous Reg...

Exceptional strength and ductility in AlCrFe1.5Ni2.6 eutectic medium-entropy alloy by Si induced lamellar to island-like structural transformation

Changing the lamellar morphology of the brittle phase in the eutectic alloy is beneficial to improving its mechanical properties. In this work, the effect of low-cost Si on the microstructure evolution and mechanical properties AlCrFe 1.5 Ni 2.6 eutectic medium entropy alloys (ME...

Abstract Trametes robiniophila Murr., an important medicinal fungus in China, pertaining to Hymenomycetes, Basidiomycotina, is well-known for its therapeutic properties, which has been used in traditional Chinese medicine for thousands of years. Many biological activities, includ...

Intelligent monitoring method for axial compression response of concrete short columns using embedded CNTs-modified cementitious sensors

Self-sensing cementitious materials, as a new type of structural-functional integrated material, are ideal monitoring materials for structural health monitoring. This study proposes an intelligent monitoring method for axial compression response of concrete short columns using em...

Adaptive Virtual Impedance Control for LVRT of Grid-Forming Energy Storage PCS in HVDC Receiving-End Grids

With the large-scale integration of high-voltage direct-current (HVDC) transmission systems, the receiving-end AC grid exhibits weak voltage-support capability. Consequently, grid-forming (GFM) battery energy storage converters are required to satisfy both current-limiting and vo...

Entertainment Sedentary Time and Subjective Well-Being in College Students: A Moderation Model of Perceived Time Poverty

This study examined the association between entertainment sedentary time (EST) and subjective well-being (SWB) among Chinese college students and further explored the moderating role of perceived time poverty (PTP). A total of 1582 college students completed questionnaires assess...

Energy-Transfer-Driven[2 + 2] Cycloaddition: Synthesisof Cyclobutane-Fused Tetracycles from Indenes and Maleimides

Abstract Molecular skeletons containing fused cyclobutane rings are of significant value in drug discovery as they can increase the fraction of sp3 carbons (Fsp3) and impart conformational rigidity. Herein, we report a visible-light photocatalytic strategy for the intermolecular...

A physics-informed PointNet + + for hand gesture recognition using radar point cloud

Hand gesture recognition based on mmWave radar point clouds has excellent potential in the human-computer interaction field. However, conventional approaches often underutilise raw data and fail to incorporate the underlying physical properties of radar echoes, resulting in a poo...

The influence of MoS 2 lubricity on the secondary cutting performance of PCD micro-groove textured tools

Micro-textured cutting tools possess unique advantages in reducing cutting forces, lowering chip temperatures, minimizing tool wear, and improving machined surface quality. Nevertheless, the secondary cutting effect induced by micro-textures impairs texture integrity and aggravat...
