Efect of Micro Abrasive Slurry Jet Polishing on Properties of Coated Cemented Carbide Tools

引用

Chinese Journal of Mechanical Engineering 2023年第5期36卷 109-119页

作者： rongjuan Wang Chengyong Wang Airport College Binzhou UniversityBinzhou 256600China School of Electromechanical Engineering Guangdong University of TechnologyGuangzhou 510006China

Owing to the popularization of coating technology, physical Vapor Deposition (PVD) coated tools have become indispensable in the cutting process. Additionally, the post-treatment of coated tools applied to industrial production can efectively enhance the surface quality of coating. To improve the processing performance of coated tools, micro abrasive slurry jet (MASJ) polishing technology is frst applied to the post-treatment of coated tools. Subsequently, the efects of process parameters on the surface quality and cutting thickness of coating are investigated via single-factor experiments. In the experiment, the best surface roughness is obtained by setting the working pressure to 0.4 MPa, particle size to 3 μm, incidence angle to 30°, and abrasive mass concentration to 100 g/L. Based on the results of the single-factor experiments, combination experiments are designed, and three types of coated tools with diferent surface qualities and coating thicknesses are obtained. The MASJ process for the post-treatment of coated tools is investigated based on a tool wear experiment and the efects of cutting parameters on the cutting force and workpiece surface quality of three types of cutting tools. The result indicates that MASJ machining can efectively improve the machining performance of coated tools.

Preparation and catalytic activity of CO-resistant catalyst core-shell Au@Pt/C for methanol oxidation

引用

Rare Metals 2012年第5期31卷 451-456页

作者： FENG rongjuan LI Min LIU Jiaxiang College of Materials Science and Engineering Laboratory of Electrochemical Process and Technology for Materials Beijing University of Chemical Technology Beijing 100029 China

Au@Pt core-shell nanoparticles were successfully synthesized by a successive reduction method and then assembled on Vulcan XC-72 carbon surface. Furthermore, its composition, morphology, structure, and activity towards methanol oxidation were characterized by UV-vis spectrometry, transmission electron microscopy (TEM), high-resolution TEM (HRTEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and cyclic voltammetry (CV). Results reveal that Au@Pt/C catalyst has better activity towards methanol oxidation than the pure platinum prepared under the same conditions. When the atomic ratio of Au to Pt in the prepared Au@Pt/C catalyst is 1:2, this catalyst exhibits best electrocatalytic activity towards methanol oxidation in acidic media, and the peak current density on this catalyst is ~2.0 times higher than that on Pt/C catalyst. The better catalytic activity of Au@Pt/C results from its better resistance to toxic CO than Pt/C because the CO oxidation on Au@Pt/C is 60 mV more negative than the case on Pt/C. © The Nonferrous Metals Society of China and Springer-Verlag Berlin Heidelberg 2012.

Productive HBV infection of well-differentiated, hNTCP-expressing human hepatoma-derived(Huh7) cells

引用

Virologica Sinica 2017年第6期32卷 465-475页

作者： Ming zhou Kaitao Zhao Yongxuan Yao Yifei Yuan rongjuan Pei Yun Wang Jizheng Chen Xue Hu Yuan zhou Xinwen Chen Chunchen Wu State Key Laboratory of Virology Wuhan Institute of Virology Chinese Academy of Sciences Shenzhen Xenotransplantation Research and Development Center State and Local Joint Cancer Genome Clinical Application of Key Technology Laboratory Shenzhen Second People's Hospital First Affiliated Hospital of Shenzhen University Institute of Immunology Zhongshan School of Medicine Guangdong Provincial Key Laboratory of Organ Donation and Transplant Immunology Sun Yat-sen University

Feasible and effective cell models for hepatitis B virus(HBV) infection are required for investigating the complete lifecycle of this virus, including the early steps of viral entry. Resistance to dimethyl sulfoxide/polyethylene glycol(DMSO/PEG), h NTCP expression, and a differentiated state are the limiting factors for successful HBV infection models. In the present study, we used a hepatoma cell line(Hu7^(hDNTCPh)) to overcome these limiting factors so that it exhibits excellent susceptibility to HBV infection. To achieve this goal, different hepatoma cell lines were tested with 2.5% DMSO/4%PEG8000, and one resistant cell line(Huh7 D) was used to construct a stable h NTCP-expressing cell line(Hu7^(hDNTCPh)) using a recombinant lentivirus system. Then, the morphological characteristics and differentiation molecular markers of Hu7^(hDNTCPh) cells with or without DMSO treatment were characterized. Finally, the susceptibility of Hu7^(hDNTCPh) cells to HBV infection was assessed. Our results showed that Huh7 D cells were resistant to 2.5% DMSO/4% PEG8000, whereas the others were not. Hu7^(hDNTCPh) cells were established to express a high level of h NTCP compared to liver extracts, and Hu7^(hDNTCPh) cells rapidly transformed into a non-dividing, well-differentiated polarized phenotype under DMSO treatment. Hu7^(hDNTCPh) cells fully supported the entire lifecycle of HBV infection. This cell culture system will be useful for the analysis of host-virus interactions, which should facilitate the discovery of antiviral drugs and vaccines.
