Radical Passivation to Incubate Closed Pore Structure and Surface Functionalities of Hard Carbon for High‐Efficiency Sodium Storage

ABSTRACT Biomass‐derived hard carbon anodes receive remarkable prospects for use in sodium‐ion battery technology. However, precise regulation of carbon crystallites is extremely critical yet formidable, which seriously retards its scale‐up industrialization. Herein, a versatile...

Predicting Engineering-Defined Failure Risk Levels of Metal-Loss-Related Pipeline Girth Weld Defects Under Incomplete Engineering Data

Predicting engineering-defined failure risk levels for pipeline girth welds …is challenging because engineering records may be incomplete Conventional models often struggle with incomplete engineering inputs, as standard imputation pipelines tend to treat estimated values as equa...

Surface mechanical attrition-induced hierarchical gradient nanostructuring enables ultrahigh strength and moderate ductility in Mg-Sn-Zn-Zr alloys

The engineering application of lightweight structural magnesium (Mg) alloys is usually impeded by the challenge of achieving high strength together with useful tensile ductility. In this study, rare-earth-free Mg-6Sn-3Zn-0.3Zr alloys with ultimate tensile strengths (UTS) of 385–4...

Homogenizing Stress Distribution to Construct a Stable LiF‐rich Solid Electrolyte Interphase in Silicon/Carbon Anodes

ABSTRACT Inducing homogeneous stress distribution is essential for enhancing the structural stability of silicon/carbon (Si/C) anodes. To this end, a liquid‐phase synthesis approach combined with an electrochemical technique is proposed to in situ construct a robust LiF‐rich inte...

Rheological Properties and Anti-Icing Performance of Asphalt Modified with Hydrophobic and Salt-Storage Components

Hydrophobic and salt-storage functionalization can impart anti-icing capability to asphalt, but the associated changes in rheological behavior should be evaluated concurrently. In this study, silica aerogel and potassium acetate-loaded diatomite were incorporated as hydrophobic a...

RAD-MRM: A Multi-Source Data-Integrated Methodology for Mining User Requirements in Industrial-Heritage Tourism

To address limited sample coverage, fragmented requirement expressions, and weak strategy translation in industrial-heritage tourism, this study proposes the Real–Agent–Designer Multi-Source Requirements Mining methodology (RAD-MRM). It integrates 26 real-user semi-structured int...

Deposition and Aero-Thermal Synergetic Design of Internal Swirl Cooling for a Turbine Blade Leading Edge: GAN-Based Optimization

Abstract The leading edge of turbine blades is subjected to extreme thermal loads, exaggerated by continuously increasing turbine inlet temperatures. This challenge has motivated the development of increasingly sophisticated internal cooling architectures. However, such intricate...

AI-Powered Student Dropout Prediction and Personalized Intervention Using TC-Net in Education
