| 1 | Machining the Integral Impeller and Blisk of Aero-Engines:A Review of Surface Finishing and Strengthening Technologies显示文摘The integral impeller and blisk of an aero-engine are high performance parts with complex structure and made of difficult-to-cut materials. The blade surfaces of the integral impeller and blisk are functional surfaces for power transmission, and their surface integrity has significant effects on the aerodynamic efficiency and service life of an aero-engine. Thus, it is indispensable to finish and strengthen the blades before use. This paper presents a comprehensive literature review of studies on finishing and strengthening technologies for the impeller and blisk of aero-engines. The review includes independent and integrated finishing and strengthening technologies and discusses advanced rotational abrasive flow machining with back-pressure used for finishing the integral impeller and blisk. A brief assessment of future research problems and directions is also presented. | Youzhi Fu Hang Gao Xuanping Wang Dongming Guo | 2017 | Chinese Journal of Mechanical Engineering2017，30，3： | 15 |
| 2 | A novel miR167a-OsARF6-OsAUX3 module regulates grain length and weight in rice显示文摘Grain size is one of the most important factors that control rice yield,as it is associated with grain weight(GW).To date,dozens of rice genes that regulate grain size have been isolated;however,the regulatory mechanism underlying GW control is not fully understood.Here,the quantitative trait locus qGL5 for grain length(GL)and GW was identified in recombinant inbred lines of 9311 and Nipponbare(NPB)and fine mapped to a candidate gene,OsAUX3.Sequence variations between 9311 and NPB in the OsAUX3 promoter and loss of function of OsAUX3 led to higher GL and GW.RNA sequencing,gene expression quantification,dual-luciferase reporter assays,chromatin immunoprecipitation-quantitative PCR,and yeast one-hybrid assays demonstrated that OsARF6 is an upstream transcription factor regulating the expression of OsAUX3.OsARF6 binds directly to the auxin response elements of the OsAUX3 promoter,covering a single-nucleotide polymorphism site between 9311 and NPB/Dongjin/Hwayoung,and thereby controls GL by altering longitudinal expansion and auxin distribution/content in glume cells.Furthermore,we showed that miR167a positively regulate GL and GW by directing OsARF6 mRNA silencing.Taken together,our study reveals that a novel miR167a-OsARF6-OsAUX3 module regulates GL and GW in rice,providing a potential target for the improvement of rice yield. | Jiyue Qiao Hongzhen Jiang Yuqing Lin Lianguang Shang Mei Wang Dongming Li Xiangdong Fu Markus Geisler Yanhua Qi Zhenyu Gao Qian Qian | 2021 | Molecular Plant2021，14，10： | 8 |
| 3 | Effect of Surface Mechanical Attrition Treatment on Tribological Behavior of the AZ31 Alloy显示文摘By surface mechanical attrition treatment(SMAT),a gradient nano structure(GNS) from the surface to center was generated in the AZ31 alloy sheet.The tribological behavior of AZ31 alloy with GNS was systematically investigated by using dry sliding tests,a 3D surface profile-meter and a scanning electron microscope equipped with an energy-dispersive spectrometer.The experimental results indicate that the Mg alloy with GNS exhibits better wear resistance comparing to the as-received sample,which is associated to the alteration of wear mechanism at different sliding speeds.The Mg alloy with GNS presents the wear mechanism of the abrasive wear at 0.05 m/s and the oxidative wear at 0.5 m/s,respectively.Moreover,the GNS can effectively promote the reaction between the oxygen and worn surface,which leads to a compact oxidation layer at 0.5 m/s.The effect of oxidation layer on the wear resistance of the Mg alloy was also discussed. | Shuangwu Xia Yong Liu Dongming Fu Bin Jin Jian Lu | 2016 | Journal of Materials Science & Technology2016，32，12： | 7 |
| 4 | Reversing cold tumors to hot: An immunoadjuvant-functionalized metalorganic framework for multimodal imaging-guided synergistic photoimmunotherapy显示文摘Immunotherapy assays using immunoadjuvants and tumor antigens could greatly increase the survival rates of patients with malignant tumors.As effective carriers,metal-organic frameworks(MOFs)have been widely utilized in cancer therapy due to their remarkable histocompatibility and low toxicity.Herein,we constructed a multimodal imaging-guided synergistic cancer photoimmunotherapy by employing a specific MOF(MIL101-NH2)as the core carrier;the MOF was dual-dressed with photoacoustic and fluorescent signal donors(indocyanine green,ICG)and immune adjuvants(cytosine-phosphate-guanine sequence,CpG)and named ICGCpG@MOF.This nanocarrier could passively target the tumor site through the EPR effect and achieve multimodal imaging(fluorescence,photoacoustic,photothermal and magnetic resonance imaging)of the tumor.Synergistic cancer photoimmunotherapy was achieved via simultaneous photodynamic and photothermal methods with 808 nm laser irradiation.ICG-CpG@MOF achieved the GSH-controlled release of immunoadjuvant into the tumor microenvironment.Furthermore,the released tumor-associated antigen along with CpG could induce the transformation of tumor cells from cold to hot by activating the immune system,which significantly enhanced tumor cytotoxicity and achieved high cure rates with minimal side-effects.This strategy utilizing multimodal imaging and synergistic cancer photoimmunotherapy provides a promising approach for the diagnosis and treatment of cancer. | Zhijin Fan Hongxing Liu Yaohua Xue Jingyan Lin Yu Fu Zhaohua Xia Dongming Pan Jian Zhang Kun Qiao Zhenzhen Zhang Yuhui Liao | 2021 | Bioactive Materials2021，6，2： | 4 |

| 7 | Crystal structure of the African swine fever virus structural protein p35 reveals its role for core shell assembly显示文摘Dear Editor,The African swine fever(ASF)is a highly contagious hemorrhagic and lethal disease in domestic pigs.The ASF outbreaks of in many Asia countries,including China,Vietnam,Mongolia,and South Korea,have posed a huge threat to the pig indusry.In the attempt to stop ASF from spreading further in China's Mainland,more than 10 million pigs have been culled since August 2018.The causative agent for ASF is a DNA virus,African swine fever virus(ASFV).Although this deadly disease has been reported in Kenya nearly one hundred years ago,there has been no vaccine for protection from ASFV infection or effective treatments to cure ASF until now. | Guobang Li Dan Fu Guangshun Zhang Dongming Zhao Mingyu Li Xue Geng Dongdong Sun Yuhui Wang Cheng Chen Peng Jiao Lin Cao Yu Guo Zihe Rao | 2020 | Protein & Cell2020，11，8： | 3 |
| 8 | Structure of African swine fever virus p15 reveals its dual role for membrane-association and DNA binding显示文摘Dear Editor, African swine fever (ASF) is a highly contagious disease of domestic pigs caused by African swine fever virus (ASFV),with mortality rates approaching 90%-100%.The first ASF case was described in 1921 in Kenya.Over the past decades, ASF has spread from Sub-Saharan Africa to Europe and Asia, and pose a huge threat to global food safety.Since the first ASF case reported in August 2018, more than 10 million pigs had been culled in China at an enormous economic loss.The risk of ASFV mutating to infect humans is extremely low.However, ASF not only threatens food security but also severely strikes the world economy in many fields, such as the global supply of the blood thinner heparin,most of which is produced from pigs.Hence, ASF is a strictly monitored infectious animal disease by OIE (World Organization for Animal Health), unfortunately, there is no approved drug or vaccine against this lethal viral disease. | Dan Fu Dongming Zhao Wei Zhang Guangshun Zhang Mingyu Li Zheng Zhang Yuhui Wang Dongdong Sun Peng Jiao Cheng Chen Yu Guo Zihe Rao | 2020 | Protein & Cell2020，11，8： | 3 |
| 9 | Characterizing the influence of gut microbiota on host tryptophan metabolism with germ-free pigs显示文摘Intestinal microbes are closely associated with host health,depending on metabolic crosstalk between the microbiota and host.Tryptophan metabolism is one of the best examples of metabolic crosstalk between intestinal microbiota and host;however,our understanding about the influence of intestinal microbiota on host tryptophan metabolism is limited.Thus,we established germ-free(GF)pig models to systemically explore the influence of intestinal microbiota on tryptophan metabolism.Five GF pigs were kept in GF conditions throughout the experiment(GF group).Six GF pigs were transplanted with fecal microbiota from donor sows to act as control pigs.Compared with control pigs,the GF pigs had remarkable alterations in tryptophan metabolism.The differential metabolites(P<0.05)were mainly found in the liver,circulation system and large intestine.Notably,the alteration of metabolites in tryptophan metabolism varied among organs,especially for the serotonin pathway.In GF pigs,tryptophan and kynurenine in the large intestine and 5-hydroxytryptophan in most organs were increased(P<0.05),while metabolites in the indole pathway in most organs were decreased(P<0.05).Collectively,our study reveals changes in tryptophan metabolism in GF pigs,highlighting the critical role of gut microbes in shaping host tryptophan metabolism. | Bingnan Liu Dongming Yu Jing Sun Xiaoyan Wu Zhongquan Xin Baichuan Deng Lijuan Fan Jian Fu Liangpeng Ge Wenkai Ren | 2022 | Animal Nutrition2022，，4： | 1 |
