Venturi-effect-inspired design of TPMS structures and their convective heat transfer characteristics

Triply periodic minimal surface (TPMS) lattice structures show great potential for compact heat exchangers and high-heat-flux electronic cooling owing to their high specific surface area, interconnected channels, and high geometric design flexibility. However, a single TPMS topol...

A new data-driven model for rapid urban low-level wind field simulation using conditional generative adversarial networks

Rapid and accurate representation of urban low-altitude wind fields is essential for understanding urban wind environments, assessing ventilation performance, and supporting emerging low-altitude aviation applications. Conventional computational fluid dynamics (CFD) provides reli...

Thermal regulation of monocrystalline and polycrystalline photovoltaic panels using phase change material for high temperature applications

Thermal regulation of photovoltaic (PV) panels is essential, as electrical efficiency decreases with increasing operating temperature. However, the electrical efficiency of these panels still no reach to maximum level, and authors have investigated various fluids and materials fo...

A Knowledge-Enhanced Iterative Reasoning Framework for Accurate and Traceable Fault Diagnosis in Distributed Service Systems

Fault diagnosis in distributed systems is challenged by complex service dependencies, cascading anomaly propagation, and similar symptom patterns. This paper proposes a knowledge-enhanced iterative reasoning framework that integrates large language models (LLMs) with a numerical...

Machine learning-enabled performance prediction and operation strategy of phase-change-material-based thermal batteries

Thermal batteries based on phase change materials (PCMs) are a key technology for energy savings and carbon reduction in building heating since latent thermal energy storage by PCMs with high energy storage density indicates great potential to utilize renewable energies. However,...

Research engagement profiles among Chinese undergraduate and postgraduate students

Research engagement is increasingly recognized as an important component of student development in higher education, particularly in medical and health sciences disciplines, but it is often measured through isolated activities or publication status alone. This study examined rese...

Redox‐Mediated Ligand Exfoliation Enables High‐Density Single‐Site Molecular Catalysts for CO 2 Electroreduction

ABSTRACT Conventional strategies for fabricating single‐site electrocatalysts often suffer from metal aggregation and insufficient exposure of active sites, limiting their efficiency in CO 2 electroreduction. Here we present a redox‐mediated ligand exfoliation method to construct...

NanomagnetitePromotes Sub-Thermophilic AnaerobicDigestion by Enhancing Electron Transfer and Electron Bifurcation

Abstract Subthermophilic anaerobic digestion accelerates hydrolytic acidification to boost methane production, yet this temperature range can suppress methanogenic activity, thereby leading to a kinetic mismatch between rapid substrate influx and limited methanogenic conversion....

Dehydration-induced CN- defects enable adaptive water regulation in Prussian blue cathodes for high-performance sodium-ion batteries

Abstract Prussian blue analogues have emerged as a promising cathode material owing to their open‑framework structure and high theoretical capacities; however, the presence and dynamic evolution of crystalline water severely constrain their electrochemical performance. Despite ex...

Evolution of the Mechanical Properties of Recycled Glass Fibers During Pyrolysis–Oxidation of Waste Wind Turbine Blades

ABSTRACT Pyrolysis is a promising route for recycling decommissioned wind turbine blades, but resin‐derived residues and thermal exposure can damage recovered glass fibers. This study investigated the surface morphology, fracture characteristics, and mechanical‐property evolution...

Allosterically Controlled Capture of Mutually Repulsive Guests With Positive Cooperativity and Ultrahigh Affinity

ABSTRACT A hexacationic cage incorporating three urea units can encapsulate two mutually repulsive anions in close proximity through a combination of hydrogen bonding and electrostatic interactions. This leads to exceptionally high binding affinities, with a K 1 × K 2 value of ap...

Draft Tube Wake Vortex Evolution and Suppression in a Pump as Turbine with Splitter Blades Based on a Modified Burgers Vortex Model

Owing to its efficient energy recovery capability, the pump as turbine (PAT) has attracted considerable attention and has been widely applied in micro hydropower systems. However, under off-design conditions, large-scale helical vortex ropes are readily induced in the draft tube,...
