Effect of Semisolid Casting and Rapid Solidification Processes on Microstructure and Damping Behavior of A356 Aluminum Alloy

This research seeks to enhance the vibration‐damping and noise‐suppression performance of automobiles, while also increasing the damping capacity of A356 aluminum alloys employed in vehicle components. Accordingly, A356 aluminum alloys were prepared via semisolid casting combined...

From Molecular Designs to Nanomaterials for Electrochemical PFAS Detection: A Review

Abstract The pervasive occurrence of per- and polyfluoroalkyl substances (PFAS) and the implementation of stringent regulatory guidelines necessitate rapid, highly sensitive analytical methodologies. Although liquid chromatography-tandem mass spectrometry (LC-MS/MS) remains the g...

Experimental study on thermal characteristics of ammonia three-dimensional oscillating heat pipes with different filling ratios

A three-dimensional oscillating heat pipe (3DOHP) transfers heat through both latent heat and sensible heat and features good temperature uniformity, compact channels, and high thermal conductivity. In this work, an ammonia-charged 3DOHP with channels gradually contracting from t...

Copper-Catalyzed Desymmetrization toward Planar Chiral Disubstituted [2.2]Paracyclophanes: A Route to Solid-State CPL Materials

Abstract Enantiomerically enriched [2.2]paracyclophanes (PCPs), particularly those bearing two functional groups on distinct decks, constitute privileged scaffolds for circularly polarized luminescence (CPL) materials owing to their inherent stable planar chirality and unique opt...

Carbon Quantum Dots and Ectoine Foliar Application Enhance Heat Tolerance of Gentiana rhodantha

Heat stress exerts detrimental effects on the survival, growth, and productivity of Gentiana rhodantha Franch. ex Hemsl., a medicinal herb endemic to Southwestern China. The application of exogenous protective substances has been widely recognized as an effective and economical s...

Green synthesis of CQDs/Ag/talc ternary composite from waste oil tea

This study presents a green and facile strategy for synthesizing a novel carbon quantum dots (CQDs)/silver (Ag)/talc ternary composite through the valorization of waste oil tea (WOT) and natural talc. The synthesis involves a three-step process: first, WOT is hydrothermally conve...

Heavy Metal Pollution in River Sediments: Risk Assessment, Source Apportionment, and Remediation—A Review Focusing on Chinese River Basins

River sediments act not only as important sinks for heavy metal pollution in watersheds, but also as potential secondary sources under changing environmental conditions. Heavy metals can enter river systems through industrial wastewater discharge, agricultural non-point runoff, u...

Polyvinylpyrrolidoneand Xanthan Gum Co-StabilizedCuprous Oxide Submicron Suspension for Effective Preservation of NaturalRubber Latex

Abstract Fresh natural rubber latex (NRL) is rich in nutrients such as proteins and sugars, making it highly susceptible to microbial growth and deterioration. Traditional ammonia-based preservatives generate irritating gases, posing hazards to worker health and the environment....

Highly Viscoelastic Rubber Extrusion: Evolution and Future Perspectives—A Review

Rubber extrusion has evolved through overlapping advances in equip design, rheological characterization, numerical modeling, sensing, and control. This structured critical narrative review synthesizes 180 sources published from 1972 to 2026, assembled through iterative keyword se...

Functional response of bacterial communities in surface sediments of qingshitan reservoir to anthropogenic disturbance

This study investigated the bacterial composition in surface sediments (0–5 cm) of Qingshitan Reservoir to elucidate their ecosystem functions in response to anthropogenic disturbances. Samples were collected in July 2023 from eight ecological points representing varying disturba...

Seismic behaviour of precast BFRP-reinforced concrete beam–column joints in sea-sand concrete

To investigate the seismic behaviour of precast seawater sea-sand concrete beam–column joints with basalt-fibre-reinforced polymer (BFRP) bars, four specimens were tested, including cast-in-situ (CiS) and precast interior/exterior joints. All specimens failed in flexure at beam e...

A Monolithic High‐Entropy Aerogel Anode for Stable and Low‐Overpotential Oxygen Evolution

ABSTRACT The oxygen evolution reaction (OER) is pivotal to the energy transition. However, its sluggish multi‐electron kinetics and poor mass transport properties at high current densities have hindered its large‐scale implementation. In this work, we have developed a high‐entrop...

Asymmetric Responses of Ecosystem Health to Urbanization in a Typical Karst City: Spatiotemporal Patterns and Driving Mechanisms in Guilin, China

ABSTRACT Urban expansion can substantially reshape ecosystem structure and functioning, especially in ecologically fragile Karst landscapes. Clarifying how ecosystem health (EH) responds to urbanization and identifying the factors that drive spatial variation in EH are important...
