Anion Immobilization-Induced Enhancement of Li+ Transport at the Polymer Electrolyte–Separator Interface

Abstract In situ polymerized electrolytes have garnered widespread attention owing to their high ionic conductivity and excellent interface compatibility. However, conventional polyethylene (PE) or polypropylene (PP) separators incorporated to maintain structural integrity typica...

Synergistic Effect of Oxygen Vacancies and Acid Sites on Selective Furfural Hydrodeoxygenation over Hollow Co@TiO x Catalysts

Abstract The development of supported non-noble metal catalysts with tailored defect structures and optimized active sites is a promising strategy for the selective hydrodeoxygenation of furfural (FAL) to 2-methylfuran (2-MF). In this study, a series of Co@TiOx-X catalysts (X = 4...

KOH-Activated Iron-Modified Corn Straw Biochar for Nitrate Removal: Preparation, Adsorption Performance, and Mechanism

Nitrate contamination of groundwater requires low-cost adsorbents with strong affinity for anionic species. This study developed an iron-modified corn straw biochar (Fe-BC) by coupling KOH activation with FeCl3 impregnation and secondary pyrolysis, thereby integrating a porous ca...

Multi-fault estimation of T–S fuzzy chaotic systems based on adjustable order observer

Chaotic systems have attracted significant attention in scientific research and engineering applications due to their unique properties. In this context, this paper investigates a class of T–S fuzzy chaotic systems with unknown inputs and external disturbances. Specifically, it a...

Thermal, mechanical, and energy-saving performance of capric acid-myristic acid/expanded perlite phase-change concrete for building envelopes

Phase-change concrete (PCC) can improve the heat-storage capacity of cement-based materials, but PCM incorporation often compromises mechanical performance. This study prepared PCC using capric acid-myristic acid (CA-MA) impregnated expanded perlite as a shape-stabilized PCM aggr...

Effects of combined admixtures on properties of ultrafine cement grouting materials and fitting characterization of water absorption

Due to their larger particle size, traditional ordinary silicate grouting materials cannot be effectively injected into the cracks of tunnel rock, resulting in suboptimal grouting performance. In this study, orthogonal experiments were conducted to systematically investigate the...

Parallel Dynamic Adaptive Transfer Function Based on Population Diversity to Solve High‐Dimensional Cancer Gene Expression Data Feature Selection Problem

ABSTRACT In cancer genomics research, feature selection (FS) of high‐dimensional gene expression data is of great significance to improve classification accuracy and reduce feature number. Aiming at the limitations of traditional transfer functions, such as nonadaptability and be...

Synergistic Thermal Rearrangement and In Situ Decarboxylation Crosslinking: Structure Tailoring of Copolyimide Membranes for Enhanced Gas Separation

Abstract To enhance the gas separation performance of polyimide membranes, the synergy of thermal rearrangement (TR) and in situ decarboxylation crosslinking represents a distinctive fabrication strategy. Herein, a diamine monomer functionalized with both carboxyl and hydroxyl gr...

Effect of position and height of liquid slag nozzle on steel-slag flow behavior in continuous casting mold

The reaction between Mn and Al in molten steel and SiO 2 in the protective slag generates MnO and Al 2 O 3 , which can cause drastic changes in the composition of the protective slag, deteriorate the quality of the casting billet, and hinder the continuous casting process. The pr...

Substrate Recognition Analysis in an Ethyl Carbamate-Hydrolyzing Esterase and Semi-Rational Baijiu Flavor Preservation

Ethyl carbamate (EC) is a widely recognized carcinogen present in fermented foods, and enzymatic degradation is a safe and effective strategy for its reduction. An EC-degrading esterase derived from Acinetobacter calcoaceticus (AcECH) was previously identified. However, volatile...

Data-Driven State of Charge Estimation for Lithium-Ion Batteries Based on Polynomial Surface Fitting Under Dynamic Driving Cycles

Abstract The accurate estimation of state of charge (SOC) for lithium-ion batteries is critically important for battery management systems (BMS) in electric vehicles, yet it remains challenging under highly dynamic driving cycles due to strong nonlinearities, sensor noise, and mo...

Residual block-based complexity-aware neural ODE fusion for image super-resolution

Image super-resolution aims to reconstruct high-resolution images from low-resolution inputs and is a core reconstruction task in computer vision. Traditional discrete residual network-based methods realize feature transformation by stacking a fixed number of layers, but are limi...

Explosion Response and Multiobjective Optimization of Butterfly-Shaped Circular Auxetic Cored Sandwich Panel Based on Machine Learning

Abstract In response to the urgent demand for blast-resistant protective structures, this study addresses two major limitations in existing research: the insufficient stiffness of conventional re-entrant auxetic honeycombs due to high porosity, and the lack of systematic multiobj...
