Interest has recently emerged in potential applications of (n, 2n) reactions of unstable nuclei. Challenges have arisen because of the scarcity of experimental cross-sectional data. This study aims to predict the (n, 2n) reaction cross-section of long-lived fission products based on a tensor model. This tensor model is an extension of the collaborative filtering algorithm used for nuclear data. It is based on tensor decomposition and completion to predict (n, 2n) reaction cross-sections; the corresponding EXFOR data are applied as training data. The reliability of the proposed tensor model was validated by comparing the calculations with data from EXFOR and different databases. Predictions were made for long-lived fission products such as 60Co, 79Se\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$${{79}} {\mathrm{Se}}$$\end{document}, 93Zr\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$${{93}}\mathrm{Zr}$$\end{document}, 107P\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$${{107}}\mathrm{P}$$\end{document}, 126Sn\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$${{126}}\mathrm{Sn}$$\end{document}, and 137Cs\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepack

Photochromic radical states in 3D covalent organic frameworks with zyg topology for enhanced photocatalysis

引用

National Science Review 2024年第7期11卷 177-188页

作者： Tian-Tian Ma Guo-Zhang huang Xiao-Han Wang yan Liang Run-Han Li Bin Wang su-Juan Yao jia-Peng Liao Shun-Li Li Yong yan Ya-Qian Lan School of Chemistry South China Normal University Department of Chemistry Guangdong Provincial Key Laboratory of Catalytic Chemistry Southern University of Science and Technology

Covalent-organic frameworks（COFs） with photoinduced donor-acceptor（D-A） radical pairs show enhanced photocatalytic activity in principle. However, achieving long-lived charge separation in COFs proves challenging due to the rapid charge recombination. Here, we develop a novel strategy by combining[6 + 4] nodes to construct zyg-type 3D COFs, first reported in COF chemistry. This structure type exhibits a fused Olympic-rings-like shape, which provides a platform for stabilizing the photoinduced D-A radical pairs. The zyg-type COFs containing catalytically active moieties such as triphenylamine and phenothiazine（PTZ） show superior photocatalytic production rates of hydrogen peroxide（H2O2）. Significantly, the photochromic radical states of these COFs show up to 400% enhancement in photocatalytic activity compared to the parent states, achieving a remarkable H2O2synthesis rate of 3324 μmol g-1h-1, which makes the PTZ-COF one of the best crystalline porous photocatalysts in H2O2production. This work will shed light on the synthesis of efficient 3D COF photocatalysts built on topologies that can facilitate photogenerating D-A radical pairs for enhanced photocatalysis.

Objective: Huazhi Rougan granules(HRGs) are a promising drug to improve alcoholic liver disease(ALD), but its mechanism remains unclear. Materials and Methods: Network pharmacology, molecular docking, and animal experiments were used to reveal the potential mechanism of HRG against ALD. Results: A total of 245 potential targets of HRG against ALD were obtained. Functional enrichment analysis suggests that HRG could synergistically regulate various biological pathways to exert therapeutic effects on ALD. Molecular docking showed that the key targets exhibited the good binding ability with the key compounds. The in vivo experiments showed that HRG can effectively alleviate pathological changes in liver tissue, improve blood lipid levels, antioxidant stress ability, and liver function, and reduce the release of inflammatory cytokines in the liver. Conclusions: This study reflects that HRG is an effective strategy for treating ALD, providing a basis for revealing the prevention and treatment mechanisms of ALD.
