| 1 | Microstructures and mechanical properties of Ti_3Al/Ni-based superalloy joints arc welded with Ti–Nb and Ti–Ni–Nb filler alloys显示文摘Dissimilar joining of Ti3Al-based alloy to Ni-based superalloy has been carried out using gas tungsten arc(GTA) welding technology with Ti–Nb and Ti–Ni–Nb filler alloys.The joint welded with the Ti–Nb filler alloy contained much less interfacial brittle phases than the one using the Ti–Ni–Nb filler alloy.The average room-temperature tensile strength of the joint welded with Ti–Nb was 202 MPa and the strength value of the one welded with Ti–Ni–Nb was 128 MPa.For both fillers,the weak links of the dissimilar joints were the weld/In718 interfaces.The presence of TiNi,TiNi3 and Ni3Nb intermetallic compounds in the joint welded with Ti–Ni–Nb induced microcracks at the weld/In718 interface and deteriorated the mechanical properties of the joint.And the adoption of the Ti–Nb filler alloy decreased the formation tendency of interfacial brittle phases to some extent and thus enhanced the tensile strength of the joint. | Bingqing Chen Huaping Xiong Bingbing Sun Siyi Tang Borui Du Neng Li | 2014 | Progress in Natural Science:Materials International2014，24，4： | 3 |
| 2 | Effects of different drying methods on drying kinetics and physicochemical properties of Chrysanthemum morifolium Ramat显示文摘The effects of infrared-assisted hot-air drying(IR-HAD),temperature,humidity controlled hot-air drying(THC-HAD),and hot-air drying(HAD)on the drying kinetics,physicochemical properties,chlorogenic acid content and microstructure of chrysanthemum were experimentally examined.The results showed that the drying time reduced with increasing air drying temperature,with IR-HAD needing the shortest drying time,followed by THC-HAD and HAD.The effective moisture diffusivities(Deff)of chrysanthemum under IR-HAD,THC-HAD,and HAD at 60℃ were 3.22×10^(-9) m^(2)/s,2.19×10^(-9) m^(2)/s,and 2.89×10^(-9) m^(2)/s,respectively.IR-HAD preserved chrysanthemum surface color better than THC-HAD and HAD,whereas the THC-HAD samples obtained higher water holding capacity(WHC),water binding capacity(WBC),and chlorogenic acid content.Additionally,peroxidase(POD)residual activity of the samples decreased with increasing blanching time.The current work provides a theoretical basis for the drying of chrysanthemum. | Borui Li Jueyi Lin Zhian Zheng Hao Duan Dong Li Min Wu | 2019 | International Journal of Agricultural and Biological Engineering2019，12，3： | 3 |
| 3 | Treadmill Exercise Relieves Chronic Restraint Stress-induced Cognitive Impairments in Mice Via Activating Protein Phosphatase 2A显示文摘Dear Editor,Aerobic exercise is well known to improve cognitive functions including hippocampus-dependent spatial memory[1]and object recognition[2].Regarding the molecular mechanisms,the indispensable role of brain-derived neurotrophic factor(BDNF)in governing exercise-induced neural plasticity has been demonstrated for the improvement of learning and memory[3].Our recent study further demonstrated the activation of mechanistic target of rapamycin pathways downstream of BDNF to drive synaptic protein synthesis upon persistent exercise[4],but leaving the effect of exercise on the post-translational modification of proteins largely unknown. | Wenjing Zhang Haining Ou Borui Zhang Meifeng Zheng Lan Yan Yang Chen Kwok-Fai So Li Zhang | 2021 | Neuroscience Bulletin2021，37，10： | 2 |
| 4 | Minimizing airfoil drag at low angles of attack with DBD-based turbulent drag reduction methods显示文摘Dielectric Barrier Discharge(DBD)based turbulent drag reduction methods are used to reduce the total drag on a NACA 0012 airfoil at low angels of attack.The interaction of DBD with turbulent boundary layer was investigated,based on which the drag reduction experiments were conducted.The results show that unidirectional steady discharge is more effective than oscillating discharge in terms of drag reduction,while steady impinging discharge fails to finish the mission(i.e.drag increase).In the best scenario,a maximum relative drag reduction as high as 64%is achieved at the freestream velocity of 5 m/s,and a drag reduction of 13.7%keeps existing at the freestream velocity of 20 m/s.For unidirectional discharge,the jet velocity ratio and the dimensionless actuator spacing are the two key parameters affecting the effectiveness.The drag reduction magnitude varies inversely with the dimensionless spacing,and a threshold value of the dimensionless actuator spac-ing of 540(approximately five times of the low-speed streak spacing)exists,above which the drag increases.When the jet velocity ratio smaller than 0.05,marginal drag variation is observed.In con-trast,when the jet velocity ratio larger than 0.05,the experimental data bifurcates,one into the drag increase zone and the other into the drag reduction zone,depending on the value of dimensionless actuator spacing.In both zones,the drag variation magnitude increases with the jet velocity ratio.The total drag reduction can be divided into the reduction in pressure drag and turbulent friction drag,as well as the increase in friction drag brought by transition promotion.The reduction in tur-bulent friction drag plays an important role in the total drag reduction. | Zhi SU Haohua ZONG Hua LIANG Jun LI Like XIE Xuecheng LIU Weiliang KONG Borui ZHENG | 2023 | Chinese Journal of Aeronautics2023，36，4： | 1 |

| 9 | Strategies for generating mouse model resources of human disease显示文摘The number of genetically modified mouse models that mimic human disease is growing rapidly,but only a tiny fraction has been commonly used.According to The Knockout Mouse Program(Lloyd,2011),a public resource of mouse embryonic stem cells containing a null mutation in every gene in the mouse genome,8,916 mutant mice lines were phenotyped up to 19 July 2022.Due to the poor correlation between the genomic responses in the mouse models and those responses in human disease,and since humans differ significantly in their genetic vulnerability to common diseases,we still need better mouse models,especially for common and chronic human diseases,including cancer,pulmonary and cardiovascular diseases,obesity and diabetes,behavioral disorders,and neurodegenerative diseases.These new models will be placed into a public repository,The China National Human Disease Animal Model Resource Center(NAMR).This project is funded by Ministry of Science and Technology of China and specializes in the creation,introduction,collection,preservation,and supply of animal model resources forhuman diseases. | Jirong Pan Ling Zhang Zhibing Huang Dalu Zhao He Li Yanan Fu Meng Wang Borui Chen Fuad A.Iraqi Grant Morahan Chuan Qin | 2023 | Protein & Cell2023，14，12： | 1 |
| 10 | A dynamic control structure of liquid-only transfer stream distillation column显示文摘The intention of this fundamental work is to explore the manipulation of a mixture of benzene,toluene and o-xylene separated from liquid-only transfer divided-wall column(LTS-DWC).First,two control structures are clearly proposed,including seven component control loops(CS1)and seven temperature control loops(CS2).However,two control structures can handle ±10% feed disturbances rather than larger feed disturbances.Subsequently,an equivalent four-column model by introducing withdraw ratio is developed to discuss the effect of two liquid-only side-stream on the overall reboiler duty.It is indicated that the second liquid-only side-stream withdraw ratio strongly affects the overall energy consumption.Hence,six-component control loops within the fixed second liquid-only side-stream withdraw ratio(CS3)is proposed and the purity of products returns to set value even as facing ±20% feed disturbances.Finally,based on the above results,it is established a temperature control structure(CS4)for controlling fixed second liquid-only side-stream withdraw ratio,which can cope with ±15% disturbances.Inspired by these findings,an insight into the dynamic control of LTS-DWC promotes the industrial implementation of DWC through new liquid-only side-stream configurations. | Borui Liu Tao Zhang Yi Zheng Kailong Li Hui Pan Hao Ling | 2023 | Chinese Journal of Chemical Engineering2023，59，7： | 0 |
| 11 | Therapeutic application of chick early amniotic fluid: effective rescue of acute myocardial ischemic injury by intravenous administration显示文摘Myocardial regeneration has been considered a promising option for the treatment of adult myocardial injuries.Previously,a chick early amniotic fluid(ceAF)preparation was shown to contain growth-related factors that pro-moted embryonic growth and cellular proliferation,though the nature of the components within ceAF were not fully defined.Here we tested whether this ceAF preparation is similarly effective in the promotion of myocardial regen-eration,which could provide an alternative therapeutic for intervening myocardial injury.In this study,a myocardial ischemic injury model was established in adult mice and pigs by multiple research entities,and we were able to show that ceAF can efficiently rescue damaged cardiac tissues and markedly improve cardiac function in both experimental models through intravenous administration.ceAF administration increased cell proliferation and improved angio-genesis,likely via down-regulation of Hippo-YAP signaling.Our data suggest that ceAF administration can effectively rescue ischemic heart injury,providing the key functional information for the further development of ceAF for use in attenuating myocardial injury. | Baiping Cui Yufan Zheng Xiang Gao Lihong Zhang Borui Li Jia Chen Xinyan Zhou Mengyuan Cai Wenrui Sun Yuting Zhang Keejong Chang Jiayi Xu Fuyin Zhu Yan Luo Tao Sun Jin Qian Ning Sun | 2022 | Cell Regeneration2022，11，1： | 0 |
| 12 | Activation of Pancreatic Acinar FXR Protects against Pancreatitis via Osginl-Mediated Restoration of Efficient Autophagy显示文摘Pancreatitis is the leading cause of hospitalization in gastroenterology,and no medications are available for treating this disease in current clinical practice.FxR plays an anti-inflammatory role in diverse inflammatory diseases,while its function in pancreatitis remains unknown.In this study,we initially observed a marked increase of nuclear FXR in pancreatic tissues of human patients ithpancratis eleting theFXRinpancreati acinar cels FXRicnara/a)ledto moreseverepancreatitis in mousemodels of caerulein-induced acute and chronic pancreatitis,while the FXR agonist GW4064 significantly attenuated pancreatitis in caerulein or arginine-induced acute pancreatitis and caerulein-induced chronic pancreatitis.FXR deletion impaired the viability and stress responses of pancreatic exocrine organoids(PEOs)in vitro.Utilizing RNA-seq and ChIP-seq of PEOs,we identified Osginl as a direct target of FxR in the exocrine pancreas,which was also increasingly expressed in human pancreatitis tissues compared to normal pancreatic tissues.Pancreatic knockdown of Osgin1 by AAV-pan abolished the therapeutic effects of FXR activation on pancreatitis,whereas pancreatic overexpression of Osginl effectively alleviated caerulein-induced pancreatitis.Mechanistically,we found that the FXR-OSGINl axis stimulated autophagic flux in the pancreatic tissues and cell lines,which was considered as the intrinsic mechanisms through which FXR-OSGINI protecting against pancreatitis.Our results highlight the protective role of the FXR-OSGIN1 axis in pancreatitis and provided a new target for the treatment of this disease. | Yufan Zheng Wenrui Sun Zhengyang Wang Jiaying Liu Cong Shan Chenxi He Borui Li Xiao Hu Wenjia Zhu Liyan Liu Fei Lan Changtao Jiang Chao Zhao Xiaobo Li Ning Sun | 2023 | Research2023，，1： | 0 |
| 13 | A semi-immobilized sulfur-rich copolymer backbone with conciliatory polymer skeleton and conductive substrates for high-performance Li-S batteries显示文摘Sulfur-rich polymers have gained a great deal of attention as the next-generation active materials in lithium-sulfur(Li-S)batteries due to their low cost,environmental compatibility,naturally sulfur uniform dispersion,and distinctive structure covalently bonding with sulfur atoms.However,the poor electrical conductivity and undesirable additional shuttle effect still hinder the commercial application of sulfur-rich polymers.Herein,we report a flexible semi-immobilization strategy to prepare allylterminated hyperbranched poly(ethyleneimine)-functionalized reduced graphene oxide(A-PEI-EGO)as sulfur-rich copolymer backbone.The semi-immobilization strategy can effectively reconcile the demand for polymer skeleton and conductive substrates through forming quaternary ammonium groups and reducing oxygen-containing functional groups,resulting in enhanced skeleton adsorption capacity and substrate electronic conductivity,respectively.Furthermore,the stable covalent bonding connection based on polymer molecules(A-PEI)not only completely prevents the additional shuttle effect of lithiation organic molecules and even sulfur-rich oligomers,but provides more inverse vulcanization active sites.As a result,the as-prepared A-PEI-EGO-S cathodes display an initial discharge capacity of1338 m A h g^(-1)at a rate of 0.1 C and an outstanding cycling stability of 0.046%capacity decay per cycle over 600 cycles.Even under 6.2 mg cm^(-2)S-loaded and sparing electrolyte of 6μL mg^(-1),the A-PEI-EGO-S cathode can also achieve a superior cycling performance of 98%capacity retention after 60 cycles,confirming its application potential. | Tianpeng Zhang Zihui Song Jinfeng Zhang Wanyuan Jiang Runyue Mao Borui Li Siyang Liu Xigao Jian Fangyuan Hu | 2023 | Journal of Energy Chemistry2023，，6： | 0 |
| 14 | Quasi-Phase Equilibrium Prediction of Multi-Element Alloys Based on Machine Learning and Deep Learning显示文摘In this study,a phase field model is established to simulate the microstructure formation during the solidification of dendrites by taking the Al-Cu-Mg ternary alloy as an example,and machine learning and deep learning methods are combined with the Kim-Kim-Suzuki(KKS)phase field model to predict the quasi-phase equilibrium.The paper first uses the least squares method to obtain the required data and then applies eight machine learning methods and five deep learning methods to train the quasi-phase equilibrium prediction models.After obtaining different models,this paper compares the reliability of the established models by using the test data and uses two evaluation criteria to analyze the performance of these models.This work find that the performance of the established deep learning models is generally better than that of the machine learning models,and the Multilayer Perceptron(MLP)based quasi-phase equilibrium prediction model achieves the best performance.Meanwhile the Convolutional Neural Network(CNN)based model also achieves competitive results.The experimental results show that the model proposed in this paper can predict the quasi-phase equilibrium of the KKS phase-field model accurately,which proves that it is feasible to combine machine learning and deep learning methods with phase-field model simulation. | Changsheng Zhu Borui Zhao Naranjo Villota Jose Luis Zihao Gao Li Feng | 2023 | Computers, Materials & Continua2023，，7： | 0 |

| 16 | The status and development strategy of coalbed methane industry in China显示文摘To achieve the goals of carbon peaking and carbon neutrality under the backgrounds of poor resource endowments, weak theoretical basis and other factors, the development of the coalbed methane industry of China faces many bottlenecks and challenges. This paper systematically analyzes the coalbed methane resources, key technologies and progress, exploration effect and production performance in China and abroad. The main problems are summarized as low exploration degree, low technical adaptability, low return on investment and small development scale. This study suggests that the coalbed methane industry in China should follow the “two-step”(short-term and long-term) development strategy. The short-term action before 2030, can be divided into two stages:(1) From the present to 2025, to achieve new breakthroughs in theory and technology, and accomplish the target of annual production of 10 billion cubic meters;(2) From 2025 to 2030, to form the technologies suitable for most geological conditions, further expand the industry scale, and achieve an annual output of 30 billion cubic meters, improving the proportion of coalbed methane in the total natural gas production. The long-term action after 2030 is to gradually realize an annual production of 100 billion cubic meters. The strategic countermeasure to achieve the above goals is to adhere to “technology+management dual wheel drive”, realize the synchronous progress of technology and management, and promote the high-quality development of the coalbed methane industry. Technically, the efforts will focus on fine and effective development of coalbed methane in the medium to shallow layers of mature fields, effective development of coalbed methane in new fields, extensive and beneficial development of deep coalbed methane, three-dimensional comingled development of coalbed methane, applying new technologies such as coalbed methane displacement by carbon dioxide, microwave heating and stimulation technology, ultrasonic stimulation, high-temperature heat injection stimulation, rock breaking by high-energy laser. In terms of management, the efforts will focus on coordinative innovation of resource, technology, talent, policy and investment, with technological innovation as the core, to realize an all-round and integrated management and promote the development of coalbed methane industry at a high level. | XU Fengyin HOU Wei XIONG Xianyue XU Borui WU Peng WANG Hongya FENG Kun YUN Jian LI Shuguang ZHANG Lei YAN Xia FANG Huijun LU Qian MAO Delei | 2023 | Petroleum Exploration and Development2023，50，4： | 0 |
