Morphology-controlled electrocatalysts with the ability of CO_(2) adsorption/activation, mass transfer, high stability and porosity are much desired in electrochemical CO_(2) reduction reaction (CO_(2)RR). Here, three kinds of multi-dimensional nanostructures (i.e., hollow sphere, nanosheets and nanofibers) have been successfully produced through the modulation of porphyrin-based covalent organic frameworks (COFs) with various modulators. The obtained nanostructures with high-stability, large surface-area, and single metal sites enable efficient CO_(2)RR into CH_(4). Notably, they all exhibit higher FE (hollow sphere, 68.2%;nanosheet, 64.2% and nanofiber, 71.0%, -0.9 V) than COF-366-Cu (43.0%, -0.9 V) after morphology control. Noteworthy, the FE of COF-366-Cu (HS) keeps higher than 52.4% over a wide potential range from -0.9 V to -1.1 V and the achieved FECH_(4) + C_(2)H_(4) (82.8%, -0.9 V) is superior to most of reported COFs and copper-based electrocatalysts. This work paves a new way in the exploration of COF-based multi-dimensional nanostructures applicable in efficient CO_(2)RR to CH_(4).

Channel pruning on frequency response

Science China(Information Sciences) 2025年第1期68卷 159-170页

Network pruning has a significant role in reducing network parameters and accelerating the inference time of the network. Some existing methods prune the network based on the frequency of the data, and finally obtain a sub-network with high accuracy. However, according to our experimental analysis, different frequencies of information in the data contribute differently to the accuracy of the model, and using this information directly for pruning without making a selection will lead to incorrect results. We believe that pruning should retain the convolutional kernels in the network that process important information, while those kernels that process unimportant information should be removed. In this paper, we first investigate the meaning of each frequency band information in the spectrum and their contribution to the prediction accuracy of the network,and according to these results, we propose a new pruning method based on frequency response(PFR). Our PFR finds and removes the convolutional kernels in the network that specialize in processing unimportant information, resulting in a compact neural network model. PFR obtains significant experimental results on different datasets, for example, a 56.0% raduction of float points operations(FLOPs) on Res Net-50 and only 0.37% of Top-1 accuracy degradation on the Image Net dataset.

Unlocking the stable interface in aqueous zinc-ion battery with multifunctional xylose-based electrolyte additives

Journal of Energy Chemistry 2025年第1期100卷 770-778页

The growth of dendrites and the side reactions occurring at the Zn anode pose significant challenges to the commercialization of aqueous Zn-ion batteries（AziBs）. These challenges arise from the inherent conflict between mass transfer and electrochemical kinetics. In this study, we propose the use of a multifunctional electrolyte additive based on the xylose（Xylo） molecule to address these issues by modulating the solvation structure and electrode/electrolyte interface, thereby stabilizing the Zn anode. The introduction of the additive alters the solvation structure, creating steric hindrance that impedes charge transfer and then reduces electrochemical kinetics. Furthermore, in-situ analyses demonstrate that the reconstructed electrode/electrolyte interface facilitates stable and rapid Zn2+ion migration and suppresses corrosion and hydrogen evolution reactions. As a result, symmetric cells incorporating the Xylo additive exhibit significantly enhanced reversibility during the Zn plating/stripping process, with an impressively long lifespan of up to 1986 h, compared to cells using pure ZnSO4electrolyte. When combined with a polyaniline cathode, the full cells demonstrate improved capacity and long-term cyclic stability. This work offers an effective direction for improving the stability of Zn anode via electrolyte design, as well as highperformance AziBs.

Sea cucumber intestinal hydrolysates alleviate insulin resistance through regulating IRS1/PI3K/AKT signaling pathway mediated by glutamine metabolism in high-fat and high-sucrose diet-induced mice

引用

Food Science and Human Wellness 2025年

作者： Meng Wang Man Yao Hao yue Yingying Tian zifang zhao Changhu Xue Tiantian Zhang Yuming Wang SKL of Marine Food Processing & Safety Control， College of Food Science and Engineering， Ocean University of China Institute of Food & Nutrition Science and Technology， Shandong Academy of Agricultural Sciences Hainan Huayan Collagen Technology Co. Sanya Institute of Oceanography， Ocean University of China

It has been reported that sea cucumber intestine hydrolysates (SCIH) could promote glutamine metabolism in mice， while there is a close connection between glutamine metabolism and insulin sensitivity. However， the effect of SCIH on insulin resistance is still unclear. The results showed that SCIH hydrolyzed by flavor protease had significant activity using the insulin-induced HepG2 cell model. Animal experiments exhibited that SCIH supplementation significantly improved the high-fat and high-sucrose diet-induced impaired glucose tolerance， reduced fasting serum glucose and glycosylated serum protein. Besides， SCIH ameliorated islet vacuolization and decreased the pancreas TNF-α and IL-6 by 32.1% and 36.2%， respectively. Immunofluorescence staining results showed that SCIH promoted insulin secretion. Interestingly， SCIH significantly increased the liver glutamine levels and upregulated the expression of glutaminase1 (GLS1) and glutamate dehydrogenase 1 (GLUD1). Furthermore， SCIH increased liver acetyl-CoA levels to enhance histone acetylation and activate the gene transcription and translation on glucose metabolism-related IRS/PI3K/AKT signaling pathway， thereby attenuating insulin resistance. The present findings proposed the potential value for developing functional foods in SCIH utilization.
