Electrical insulation enhancement of the Al 2 O 3 composite films at high temperature by oxygen vacancy suppression

Abstract The electrical insulation film is critical for the reliable operation of Ultra-high temperature thin-film sensors (UTTSs) at elevated temperatures. However, the resistance of the insulation film easily decline at high temperatures due to the formation of the oxygen vacan...

Machine Learning Prediction Models for Compressive Strength of Concrete with Industrial Waste Materials at Elevated Temperatures

Background: Concretes utilized in very high temperature zones, for example, furnaces in chimneys, refineries, and nuclear facilities for the disposal of waste, are exposed not only to temperature changes but also to variations in humidity, all of which drastically impact their Co...

Achieving breakthrough high strength in AZ31 magnesium alloy bar via a novel single-pass extrusion process

AZ31 magnesium alloy generally suffers from insufficient room-temperature strength. Meanwhile, conventional processing routes offer limited strengthening efficiency, and severe plastic deformation (SPD) processes face difficulties in industrial upscaling. To address these bottlen...

Scavenger Receptor Class B Type 1 Mediated Transport Enables Delivery Across Capillarized Liver Sinusoids in Metabolic Dysfunction-Associated Steatohepatitis

Abstract Liver fibrosis in metabolic dysfunction associated steatohepatitis (MASH) lacks effective therapies, in part because therapeutic agents poorly penetrate the capillarized sinusoidal endothelium. As fibrosis progresses, liver sinusoidal endothelial cells (LSECs) become def...

Anomalous deformation behavior and underlying mechanisms of Mg-Nd-Zr-Ca alloy during low-temperature hot compression

The anomalous deformation behavior of a Mg-1.8Nd-0.4Zr-0.3Ca (wt%) alloy during hot compression at low temperatures (180–330 °C) and strain rates of 0.001–10 s⁻¹ was systematically investigated. The flow stress exhibits an abnormal increase with decreasing strain rate at 180 °C,...

Biobased Fibrous Films Enabling Synergistic Thermal Conduction and Radiative Cooling for Personal Thermal Management

Abstract Personal thermal management materials are increasingly in demand under intensifying outdoor heat exposure and global warming. However, simultaneously achieving efficient radiative cooling, rapid thermal conduction, mechanical flexibility, and sustainability within a simp...

Architecting optimized heterostructure for exceptional strength-ductility synergy in Mg-Gd-Y-Zn-Mn alloy

Achieving a superior combination of strength and ductility in magnesium (Mg) alloys remains challenging. Heterogeneous microstructures have been demonstrated as an effective strategy to overcome this dilemma. In this study, a remarkable strength-ductility synergy is sustained in...
