Hydrogels are extensively utilized as strain sensors in the domain of wearable devices. However, balancing mechanical properties, adhesion, and self-healing capabilities in hydrogel sensors has consistently been a research challenge. In this study, a novel P(AA-AMPS)/PEI hydrogel was synthesized through a straightforward one-step radical polymerization with acrylic acid (AA) and 2-acrylamido-2-methyl-1-propanesulfonic acid (AMPS) as monomers, polyethyleneimine (PEI) and AlCl3 as physical crosslinkers to effectively solve the above challenge. The P(AA-AMPS)/PEI hydrogel demonstrated good mechanical properties with a tensile strength of 42.54 kPa, a high self-adhesion strength to pigskin up to 37.48 kPa, and rapid self-healing efficiency of 100 % after 1 h. The P(AA-AMPS)/PEI hydrogel sensor exhibited good stability, precision, and dependability in real-time monitoring of both subtle and large human movements due to the ultra-high sensitivity (GF values were 5.92, 13.82, and 20.89 within the strain ranges of 0–300 %, 300–600 %, and 600–850 %). It must be noted that the sensing performance of the healed P(AA-AMPS)/PEI hydrogel remained unchanged. The developed hydrogel sensor exhibited promising applications in wearable devices, electronic skin, and human–machine interaction. © 2024 Elsevier Ltd

Optimization of acrylonitrile exhaust gas absorbent based on experimental and quantum computational chemistry

Journal of Molecular Liquids 2025年 429卷

作者： Wei, Yanyu Jin, Zekai Wang, Li Li, Sisi Zhang, Gang Cai, Zhengchun Li, Yonghong Fu, Bo Key Laboratory for Green Chemical Technology of Ministry of Education School of Chemical Engineering and Technology Tianjin University Tianjin300350 China Jiangsu Co-Innovation Center of Efficient Processing and Utilization of Forest Resources Jiangsu Provincial Key Lab for the Chemistry and Utilization of Agroforest Biomass College of Chemical Engineering Nanjing Forestry University Nanjing210037 China

This study aims to develop an efficient absorbent for acrylonitrile (AN) waste gas. In industry, choosing an efficient absorbent is an effective way to improve the efficiency of exhaust gas absorption. Thirteen common solvents were initially screened based on their gas–liquid partition coefficients, and five solvents—NMP, TEA, SUL, TGDE, and TGBE—were selected for further investigation. The molecular interactions between AN and these solvents were analyzed using advanced computational methods, including electrostatic potential (ESP) analysis, atoms in molecules (AIM) analysis, independent gradient model (IGM) analysis, and symmetry-adapted perturbation theory (SAPT) energy decomposition. The results revealed that dispersion and electrostatic forces were the primary contributors to the interactions between AN and the absorbents. Based on these computational findings, experimental tests were conducted using TGBE as the main solvent combined with other co-solvents. The composite solvent of TGBE and SUL demonstrated the best performance, maintaining an absorption efficiency above 93.5% after nine absorption–desorption cycles, indicating strong regeneration potential and practical applicability for AN waste gas treatment. This study provides valuable insights into the design of efficient absorbents for AN treatment and supports the development of sustainable industrial practices. © 2025

The rising water crisis and challenges associated with the use of petrochemicals have resulted in an increased interest in using renewable biopolymer-based materials for decontaminating water and wastewater effluents. Lignin is the second most abundant natural polymer that is produced in large quantities in the pulping and biorefinery industries. Lignin has received a great deal of attention in the last decades for developing lignin-based polymers as effective coagulants and flocculants. This review paper provides a comprehensive overview of the primary research conducted to develop different types of lignin-based flocculants for treating colloidal suspensions and solutions in single and dual polymer systems. The modification strategies, including sulfonation, oxidation, Mannich, carboxymethylation, graft copolymerization, and crosslinking, are reviewed as strategies for altering the physicochemical characteristics of technical lignins for mimicking flocculants. Moreover, the benefits, challenges, and future opportunities related to the preparation and employment of lignin-based flocculants are also discussed. © 2025 The Authors

Action recognition is an important topic in computer vision and most current work focuses on view-dependent representations. In this paper, we develop a novel free viewpoint action recognition based on Self-similarity matrix (SSM), which tends to be stable across views. We choose Local Self-similarity (LSS) descriptor as our low-level feature, then SSM is calculated by computing the similarity between any pair of frame features. Each video sequence is represented using a diagonal descriptor vector extracted from the SSM. Support Vector Machines (SVM) is employed for classification. The encouraging experimental results on the public IXMAS multi-view data set demonstrate effectiveness of the proposed method.

作者： Zhao, Huan Hu, Lian Peng, Xiujuan Wang, Gangjin Yu, Fei Xu, Cheng School of Information Science and Engineering Hunan University Changsha China Jiangsu Provincial Key Lab of Image Processing and Image Communications Nanjing University of Posts and Telecommunications Nanjing China

FastICA is a kind of independent component analysis (ICA), which is robust and high performance algorithm, it can strongly remove signal correlation and ensure each signal to be independence. Through perceptual test, improving that RASTA is an idea which can denoise effectively. First, we remove signal correlation through FastICA algorithm, then we use RASTA filter to filtering the ceptral coefficients. Finally, we reduce dimension of the cepstral coefficients by the variances of cepstral coefficients in different dimension and obtain our features. By the HTK3.3, the speech feature extraction which was presented in this paper show the better robust in recognition experiment. © 2011 ACADEMY PUBLISHER.
