Anion exchange membranes with a semi-interpenetrating polymer network using 1,6-dibromohexane as bifunctional crosslinker

引用

Chinese Journal of Chemical Engineering 2024年第08期 199-208页

作者： Aijie Li Zhanliang Wang Zhihao Si Lu Lu Peipei Huang Jinhong Liu Songyuan Yao Peiyong Qin Xinmiao Zhang National Energy R&D Center for Biorefinery College of Life Science and Technology Beijing University of Chemical Technology Paris Curie Engineer School Beijing University of Chemical Technology environmental protection research institute Beijing Research Institute of Chemical Industry

An anion exchange membrane（AEM） is generally expected to possess high ion exchange capacity（IEC）,low water uptake（WU）, and high mechanical strength when applied to electrodialysis *** different types of AEMs, semi-interpenetrating polymer networks（SIPNs） have been suggested for their structural superiorities, i.e., the tunable local density of ion exchange groups for IEC and the restrained leaching of hygroscopic groups by insolubility for WU. Unfortunately, the conventional SIPN AEMs still struggle to balances IEC, WU, and mechanical strength simultaneously, due to the lack of the compact crosslinking region. In this work, we proposed a novel SIPN structure of polyvinylidene difluoride/polyvinylimidazole/1,6-dibromohexane（PVDF/PVIm/DBH）. On the one hand, DBH with two cationic groups of imidazole groups are introduced to enhance the ion conductivity, which is different from the conventional monofunctional modifier with only one cationic group. On the other hand, DBH has the ability to bridge with PVIm, where the mechanical strength of the resulting AEM is increased by the increase of crosslinking degree. Results show that a low WU of 38.1% to 62.6%, high IEC of 2.12—2.22 mmol·g-1, and excellent tensile strength of 3.54—12.35 MPa for PVDF/PVIm/DBH membrane are achieved. This work opens a new avenue for achieving the high-quality AEMs.

Microplastics may reduce the fish bioaccumulation of organic pollutants

引用

Science China Technological Sciences 2024年

作者： YANG Bing ZHOU Xian HU XiaoJie QIN Chao WANG Jian GAO YanZheng institute of Organic Contaminant Control and Soil Remediation College of Resource and Environmental Sciences Nanjing Agricultural University

Microplastics have frequently been regarded as a threat to aquatic organisms due to their potential to enhance the accessibility of organic pollutants. However, studies of microplastics as “carriers” in the process of bioaccumulation have only been conducted on a few organic contaminants. In this study, we employed machine learning algorithms to predict the sorption capacity of 83exogenous organic pollutants（in CCL4） on microplastics, the prediction model exhibits exceptional predictive performance,achieving R2values of 0.8651 and 0.6962, RMSE values of 0.4625 and 0.1841 for the sorption coefficients Kfand n, respectively,and quantitatively estimated the contribution of microplastics to the bioaccumulation levels of organic pollutants in Gadus morhua. By considering both natural and microplastic-ingesting pathways, we demonstrated that the ingestion of microplastics containing organic pollutants facilitates the entry of organic pollutants into Gadus morhua. However, due to their robust sorption capacity, microplastics transport the organic pollutants accumulated through the natural pathway out of the fish, thereby preventing bioaccumulation. These findings elucidate the “cleaning” mechanism of microplastics concerning various organic pollutants in aquatic organisms, providing valuable insights for accurately assessing the risk of microplastics in aquatic environments.

Sparse convolutional model with semantic expression for waste electrical appliances recognition

Science China(Technological Sciences) 2024年第9期67卷 2881-2893页

作者： HAN HongGui LIU YiMing LI FangYu DU YongPing Faculty of Information Technology Beijing University of TechnologyBeijing 100124China Beijing Key Laboratory of Computational Intelligence and Intelligent System Beijing 100124China Engineering research Center of Digital Community Ministry of EducationBeijing 100124China Beijing Artificial Intelligence institute and Beijing Laboratory for Intelligent environmental protection Beijing 100124China

Deep neural networks play an important role in the recognition of waste electrical appliances. However, deep neural network components still lack reliability in decision-making features. To address this problem, a sparse convolutional model with semantic expression(SCMSE) is proposed. First, a low-rank sparse semantic expression component, combining the benefits of residual networks and sparse representation, is adapted to enhance sparse feature extraction and semantic expression. Second, a reliable network architecture is obtained by iterating the optimal sparse solution, enhancing semantic expression. Finally, the results of visualization experiments on the waste electrical appliances dataset demonstrate that the proposed SCMSE can obtain excellent semantic performance.
