| 1 | Kinetics of the hydrogen absorption and desorption processes of hydrogen storage alloys: A review显示文摘High hydrogen absorption and desorption rates are two significant index parameters for the applications of hydrogen storage tanks.The analysis of the hydrogen absorption and desorption behavior using the isothermal kinetic models is an efficient way to investigate the kinetic mechanism.Multitudinous kinetic models have been developed to describe the kinetic process.However,these kinetic models were de-duced based on some assumptions and only appropriate for specific kinetic measurement methods and rate-controlling steps(RCSs),which sometimes lead to confusion during application.The kinetic analysis procedures using these kinetic models,as well as the key kinetic parameters,are unclear for many researchers who are unfamiliar with this field.These problems will prevent the kinetic models and their analysis methods from revealing the kinetic mechanism of hydrogen storage alloys.Thus,this review mainly focuses on the summarization of kinetic models based on different kinetic measurement methods and RCSs for the chemisorption,surface penetration,diffusion of hydrogen,nucleation and growth,and chemical reaction processes.The analysis procedures of kinetic experimental data are expounded,as well as the effects of temperature,hydrogen pressure,and particle radius.The applications of the kinetic models for different hydrogen storage alloys are also introduced. | Qian Li Xi Lin Qun Luo Yuʼan Chen Jingfeng Wang Bin Jiang Fusheng Pan | 2022 | International Journal of Minerals,Metallurgy and Materials2022，29，1： | 9 |
| 2 | IGHG1 promotes motility likely through epithelial-mesenchymal transition in ovarian cancer显示文摘Objective: Ovarian cancer(OC) is one of the leading causes of death for female cancer patients. COC166-9 is an OC-specific monoclonal antibody and we have identified immunoglobulin γ-1 heavy chain constant region(IGHG1) as its antigen. We explore the function of IGHG1 in proliferation, apoptosis and motility of OC cells further in this research.Methods: IGHG1 expression in OC specimens was detected through immunohistochemistry. Real-time quantitative polymerase chain reaction(RT-q PCR) or western blotting assay was used to test IGHG1 expression in OC cells. Viability of OC cells was tested by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide(MTT)assay. Flow cytometry or western blotting assay was used to detect cell cycle and apoptosis. Cellular motility was analyzed by using transwell assay and the markers of epithelial-mesenchymal transition(EMT) were tested through immunoblots.Results: Although it exerts negligible effect on the viability and apoptosis of OC cells, IGHG1 could promote migration and invasion of malignant cells in vitro. Mechanistically, IGHG1 increases the expression of N-cadherin and Vimentin while decreases E-cadherin expression. Additionally, IGHG1 expression in OC specimens is higher relative to the paired normal counterparts. Further analysis demonstrates that the increased IGHG1 expression correlates positively with the lymph node metastasis of OC.Conclusions: IGHG1 promotes the motility of OC cells likely through executing the EMT program. Increased IGHG1 expression in OC specimens is associated with the lymph node metastasis. | Jingfeng Qian Fangxing Ji Xue Ye Hongyan Cheng Ruiqiong Ma Xiaohong Chang Chengchao Shou Heng Cui | 2018 | Chinese Journal of Cancer Research2018，30，2： | 6 |

| 7 | MalFSM:Feature Subset Selection Method for Malware Family Classification显示文摘Malware detection has been a hot spot in cyberspace security and academic research.We investigate the correlation between the opcode features of malicious samples and perform feature extraction,selection and fusion by filtering redundant features,thus alleviating the dimensional disaster problem and achieving efficient identification of malware families for proper classification.Malware authors use obfuscation technology to generate a large number of malware variants,which imposes a heavy analysis burden on security researchers and consumes a lot of resources in both time and space.To this end,we propose the MalFSM framework.Through the feature selection method,we reduce the 735 opcode features contained in the Kaggle dataset to 16,and then fuse on metadata features(count of file lines and file size)for a total of 18 features,and find that the machine learning classification is efficient and high accuracy.We analyzed the correlation between the opcode features of malicious samples and interpreted the selected features.Our comprehensive experiments show that the highest classification accuracy of MalFSM can reach up to 98.6% and the classification time is only 7.76 s on the Kaggle malware dataset of Microsoft. | KONG Zixiao XUE Jingfeng WANG Yong ZHANG Qian HAN Weijie ZHU Yufen | 2023 | Chinese Journal of Electronics2023，32，1： | 0 |
| 8 | Improved hydrogen storage kinetics of MgH_(2) using TiFe_(0.92)Mn_(0.04)Co_(0.04) with in-situ generated α-Fe as catalyst显示文摘While TiFe alloy has recently attracted attention as the efficient catalyst to enhance de/hydrogenation rates of Mg/MgH_(2),the difficulty of its activation characteristics has hindered further improvement of reaction kinetics.Herein,we report that the TiFe_(0.92)Mn_(0.04)Co_(0.04) catalyst can overcome the abovementioned challenges.The synthesized MgH_(2)-30 wt% TiFe_(0.92)Mn_(0.04)Co_(0.04) can release 4.5 wt%of hydrogen in 16 min at 250℃,three times as fast as MgH_(2).The activation energy of dehydrogenation was as low as 84.6 kJ mol^(-1),which is 46.8%reduced from pure MgH_(2).No clear degradation of reaction rates and hydrogen storage capacity was observed for at least 30 cycles.Structural studies reveal that TiFe_(0.92)Mn_(0.04)Co_(0.04) partially decomposes to in-situ generatedα-Fe particles dispersed on TiFe_(0.92)Mn_(0.04)Co_(0.04).The presence ofα-Fe reduces the formation of an oxide layer on TiFe_(0.92)Mn_(0.04)Co_(0.04),enabling the activation processes.At the same time,the hydrogen incorporation capabilities of TiFe_(0.92)Mn_(0.04)Co_(0.04) can provide more hydrogen diffusion paths,which promote hydrogen dissociation and diffusion.These discoveries demonstrate the advanced nature and importance of combining the in-situ generatedα-Fe with TiFe_(0.92)Mn_(0.04)Co_(0.04).It provides a new strategy for designing highly efficient and stable catalysts for Mg-based hydrogen storage materials. | Zefeng Li Yangfan Lu Jingfeng Wang Yu'an Chen Qian Li Fushen Pan | 2024 | Materials Reports(Energy)2024，4，1： | 0 |
