| 1 | Blocking the butyrate-formation pathway impairs hydrogen production in Clostridium perfringens显示文摘使竞争小径失去活性将改进引起发酵的氢生产由要求厌氧微生物,例如那些类 Clostridium。在我们的以前的学习,当时, l 喂奶脱氢酶在被使失去活性的 Clostridium perfringens W13 的氢收益增加了 44% 与它的原来的紧张 W12 相比。在这研究,我们探索了堵住丁酸盐形成小径是否将增加氢产量。acetyl-CoA acetyltransferase 基因(atoB ) 把第一酶编码为这条小径,它最终形成丁酸盐。Clostridium perfringens W14 和 W15 被分别地在 W13 和 W12 使 atoB 失去活性构造。W14 和 W15 的氢收益分别地是 W13 和 W12 的 44% 那些和 33% 。atoB 的 Inactivation 减少了 pyruvate 合成和它的变换到在异种,和在 W14 和 W15 的增加的乙醇形成的 acetyl-CoA。Proteomic 分析表明涉及丁酸盐形成小径的五蛋白质的表情在 W14 是起来调整的。我们的结果建议那丁酸盐形成缺乏改进了乙醇生产然而并非氢生产,显示为在 C 的氢生产的丁酸盐形成小径的重要性。perfringens。 | Ruisong Yu Ruofan Wang Ting Bi Weining Sun Zhihua Zhou | 2013 | Acta Biochimica et Biophysica Sinica2013，45，5： | 2 |
| 2 | High-throughput site-specific N-glycoproteomics reveals glyco-signatures for liver disease diagnosis显示文摘The glycoproteome has emerged as a prominent target for screening biomarkers,as altered glycosylation is a hallmark of cancer cells.In this work,we incorporated tandem mass tag labeling into quantitative glycoproteomics by developing a chemical labeling-assisted complementary dissociation method for the multiplexed analysis of intact N-glycopeptides.Benefiting from the complementary nature of two different mass spectrometry dissociation methods for identification and multiplex labeling for quantification of intact N-glycopeptides,we conducted the most comprehensive site-specific and subclass-specific N-glycosylation profiling of human serum immunoglobulin G(IgG)to date.By analysing the serum of 90 human patients with varying severities of liver diseases,as well as healthy controls,we identified that the combination of IgG1-H3N5F1 and IgG4-H4N3 can be used for distinguishing between different stages of liver diseases.Finally,we used targeted parallel reaction monitoring to successfully validate the expression changes of glycosylation in liver diseases in a different sample cohort that included 45 serum samples. | Zhenyu Sun Bin Fu Guoli Wang Lei Zhang Ruofan Xu Ying Zhang Haojie Lu | 2023 | National Science Review2023，10，1： | 1 |
| 3 | A appraisement on perceived risk in e-commerce显示文摘Economic risk,financial risk and psychological risk are all perceived risk dimensions in an electronic shopping environment. While the perceived risk can be studied from the perspective of an individual decision-making process,the factors affecting consumer decision making,such as individual attitudes,experiences,external influences are important parts of designing risk management mechanism in online shopping environment. These mechanisms,such as reputation,ocr,third-party guarantees,etc.,control and reduce consumer perceived risks from different angles. | Hanpeng Zhang Ruofan Sun | 2010 | 人力资源管理:学术版2010，，2： | 0 |
| 4 | For more and purer hydrogen-the progress and challenges in water gas shift reaction显示文摘The water gas shift(WGS) reaction is a standard reaction that is widely used in industrial hydrogen production and removal of carbon monoxide. The improved catalytic performance of WGS reaction also contributes to ammonia synthesis and other reactions. Advanced catalysts have been developed for both high and low-temperature reactions and are widely used in industry. In recent years, supported metal nanoparticle catalysts have been researched due to their high metal utilization. Low-temperature catalysts have shown promising results, including high selectivity, high shift rates, and higher activity potential. Additionally, significant progress has been made in removing trace CO through the redox reaction in electrolytic cell. This paper reviews the development of WGS reaction catalysts, including the reaction mechanism, catalyst design, and innovative research methods. The catalyst plays a crucial role in the WGS reaction, and this paper provides an instant of catalyst design under different conditions. The progress of catalysts is closely related to the development of advanced characterization techniques.Furthermore, modifying the catalyst surface to enhance activity and significantly increase reaction kinetics is a current research direction. This review goals to stimulate a better understanding of catalyst design, performance optimization, and driving mechanisms, leading to further progress in this field. | Limin Zhou Yanyan Liu Shuling Liu Huanhuan Zhang Xianli Wu Ruofan Shen Tao Liu Jie Gao Kang Sun Baojun Li Jianchun Jiang | 2023 | Journal of Energy Chemistry2023，，8： | 0 |
| 5 | Current-Induced Magnetic Switching in an L1_(0) FePt Single Layer with Large Perpendicular Anisotropy Through Spin–Orbit Torque显示文摘In this study,current-induced partial magnetization-based switching was realized through the spin–orbit torque(SOT)in single-layer L1_(0) FePt with a perpendicular anisotropy(K_(u⊥))of 1.19×10^(7) erg·cm^(-3)(1 erg·cm^(-3)=0.1 J·m^(-3)),and its corresponding SOT efficiency(βDL)was 8×10^(-6) Oe·(A·cm^(-2))^(-1)(1 Oe=79.57747 A·m^(-1)),which is several times higher than that of the traditional Ta/CoFeB/MgO structure reported in past work.The SOT in the FePt films originated from the structural inversion asymmetry in the FePt films since the dislocations and defects were inhomogeneously distributed within the samples.Furthermore,the FePt grown on MgO with a granular structure had a larger effective SOT field and effi-ciency than that grown on SrTiO_(3)(STO)with a continuous structure.The SOT efficiency was found to be considerably dependent on not only the sputtering temperature-induced chemical ordering but also the lattice mismatch-induced evolution of the microstructure.Our findings can provide a useful means of efficiently electrically controlling a magnetic bit that is highly thermally stable via SOT. | Kaifeng Dong Chao Sun Laizhe Zhu Yiyi Jiao Ying Tao Xin Hu Ruofan Li Shuai Zhang Zhe Guo Shijiang Luo Xiaofei Yang Shaoping Li Long You | 2022 | Engineering2022，8，5： | 0 |
