A Bio-Inspired Solid-Waste Recycling Strategy: Construction of Fluoride-Free, Fly Ash-Based, and Superhydrophobic Coatings for Enhancing the Fire Protection and Surface Functionality of Steel Structures

Abstract To address the critical issues of fire risk and surface performance in steel structures, functionalized coatings were emerged as one of the most effective strategies. Inspired by the unique wettability of natural organisms, a superhydrophobic multifunctional coating was...

Synergistic coupling of spirobifluorene-based 3D rigid branched backbone and flexible ethoxy-containing side chains for anion exchange membranes

The creation of anion exchange membranes (AEMs) that integrate high ionic conductivity with excellent dimensional stability is crucial for facilitating the efficiency improvement of AEM fuel cell systems. We proposed a molecular synergistic strategy to fabricate high-performance...

Beautification and obscuration: the unintended consequences of jointly constructed anti-stigma narratives on medical resource inequality for autistic individuals

Abstract Background Neurodiversity emerged from autistic self-advocacy communities in the mid-1990s. Other anti-stigmatization narratives are widely advocated to reduce autism-related stigma. In China, parent-led organizations and charitable organizations have played an indispens...

Bulk Synthesis of Styrene– N ‐Phenylmaleimide–Maleic Anhydride Copolymer for Preparing Heat‐Resistant ABS Resins With Superior Toughness

ABSTRACT To overcome the limitation imposed by the low heat distortion temperature (HDT) of ABS, which restricts its use in electronic packaging and automotive components, a styrene– N ‐phenylmaleimide–maleic anhydride terpolymer (SMIH) was synthesized via bulk polymerization as...

Construction of Bioinspired, Multifunctional, Durable, and Superhydrophobic Sponges for Oil–Water Separation Based on Recycled Flexible Foam

Abstract Aiming at simultaneously settling the problem of waste resource recycling, oily wastewater pollution/health risk, flammability, and durability of traditional oil–water separation materials, this work developed the superhydrophobic/superoleophilic sponge materials (P/APP@...

Semi-Supervised Gearbox Anomaly Detection Under Variable Operating Conditions

Feature distributions shift under variable-speed gearbox operation, which can cause a model trained only on healthy samples to misclassify normal operating changes as anomalies. A semi-supervised anomaly detection method is proposed in this study. Using healthy data, the method f...

Catalytic Asymmetric Spiroannulation to Access Polycyclic Spiro Enones via Transient Axial-to-Point Chirality Induction and Transfer

Chiral spirocycles exhibit tremendous potential in drug discovery and asymmetric synthesis, owing to their unique three-dimensional rigid framework and superior stability. However, stereoselective construction of polycyclic spiro compounds through a single catalytic transformatio...

Human–machine collaborative driving collision avoidance control based on Bayesian risk estimation

How to address the challenges in human–machine cooperative control of intelligent vehicle is still an important issue, which include the conflicting objectives between driver and controller, the difficulty in fusing multi-source risk information from both vehicle and driver state...

Direct Yaw Moment Control of Distributed-Drive Electric Vehicles via Multi-Agent Full-Order Terminal Sliding Mode

To improve the yaw-stability tracking accuracy and torque smoothness of distributed-drive electric vehicles (DDEVs) under high-speed double-lane-change maneuvers and crosswind disturbances, this paper proposes a multi-agent-system (MAS)-based direct yaw moment control (DYC) metho...

Preparation and Characterization of Core–Shell‐Structured Polyaniline Nanocomposites With Combined Electrical Conductivity, Magnetic Properties, and Fluorescence Performance

ABSTRACT A Ni 0.5 Zn 0.5 Fe 2 O 4/ SiW 11 Ni/PANI core–shell nanocomposite was prepared via one‐step inverse microemulsion polymerization, achieving integrated control of conductivity, soft magnetism, and blue photoluminescence. Spinel Ni–Zn ferrite (∼15 nm, 59.95 emu/g) was firs...
