| 1 | Amino-functionalized Ti_(3)C_(2)T_(x) with anti-corrosive/wear function for waterborne epoxy coating显示文摘Two-dimensional Ti_(3)C_(2)T_(x) flakes have great application potential in various areas due to their optical,electronic,electrochemical and mechanical properties,but their anti-corrosion and wear-resistance performance were not well understood.The difficulties in achieving good dispersity and interface interaction of inorganic additives in organic coatings hinder the incorporation of Ti_(3)C_(2)T_(x) into the epoxy coating.Here,few-layered Ti_(3)C_(2)T_(x) sheets with amino-functionalization were prepared,and as reinforced-additives were added into the waterborne epoxy coating.Anti-corrosion and tribological properties of as-prepared composite coatings were investigated in detail.The results reveal that the composite coating with 0.5 wt.%amino-functionalized Ti_(3)C_(2)T_(x) sheets shows excellent corrosion protection(the lowest frequency impedance was 3.12×10^(9) cm^(2))and wear resistance(wear rate was reduced by 72.74%).The greatly improving performance of composite coatings mainly depends on:(a)good dispersity and compatibility of amino-functionalized Ti_(3)C_(2)T_(x) in organic matrix,(b)high adhesion strength between coating and metal substrate and(c)the intrinsic properties of Ti3C2Tx sheets.The work provides a good path for applications of MXene as multifunctional additives. | Han Yan Meng Cai Wen Li Xiaoqiang Fan Minhao Zhu | 2020 | Journal of Materials Science & Technology2020，54，19： | 7 |
| 2 | Comparative study on corrosion resistance and lubrication function of lithium complex grease and polyurea grease显示文摘In this study,lithium complex grease(LCG)and polyurea grease(PUG)were synthesized using mineral oil(500 SN)and polyalphaolefin(PAO40)as base oil,adsorbed onto lithium complex soap and polyurea as thickeners,respectively.The effects of grease formulation(thickener and base oil with different amounts(80,85,and 90 wt%)on the corrosion resistance and lubrication function were investigated in detail.The results have verified that the as-prepared greases have good anti-corrosion ability,ascribed to good salt-spray resistance and sealing function.Furthermore,the increase in the amount of base oil reduces the friction of the contact interface to some extent,whereas the wear resistance of these greases is not consistent with the friction reduction,because the thickener has a significant influence on the tribological property of greases,especially load-carrying capacity.PUG displays better physicochemical performance and lubrication function than LCG under the same conditions,mainly depending on the component/structure of polyurea thickener.The polyurea grease with 90 wt%PAO displays the best wear resistance owing to the synergistic lubrication of grease-film and tribochemical film,composed of Fe_(2)O_(3),FeO(OH),and nitrogen oxide. | Guanlin REN Pengfei ZHANG Xiangyuan YE Wen LI Xiaoqiang FAN Minhao ZHU | 2021 | Friction2021，9，1： | 5 |
| 3 | Improving the lubrication and anti-corrosion performance of polyurea grease via ingredient optimization显示文摘Thickener formulation plays a significant role in the performance characteristics of grease.The polyurea greases(PUGs)were synthesized using mineral oil(500SN)as the base oil,and by regulating the reaction of diphenylmethane diisocyanate(MDI)and different organic amines.The as‐prepared PUGs from the reaction of MDI and cyclohexylamine/p‐toluidine exhibit the optimum physicochemical and friction‐wear properties,confirming that the regulation of thickener formulation can improve the performance characteristics of grease,including friction reduction,wear,corrosion resistance,and load‐carrying capacity.The anticorrosion and lubrication properties of as‐prepared PUGs depend on good sealing functions and a boundary lubrication film(synergy of grease‐film and tribo‐chemical reaction film),as well as their chemical components and structure. | Guanlin REN Xiaowen SUN Wen LI Hao LI Lin ZHANG Xiaoqiang FAN Dongshan LI Minhao ZHU | 2021 | Friction2021，9，5： | 4 |
| 4 | Molecular architecture of the luminal ring of the Xenopus laevis nuclear pore complex显示文摘The nuclear pore complex(NPC)mediates the flow of substances between the nucleus and cytoplasm in eukaryotic cells.Here we report the cryo-electron tomography(cryo-ET)structure of the luminal ring(LR)of the NPC from Xenopus laevis oocyte.The observed key structural features of the LR are independently confirmed by single-particle cryo-electron microscopy(cryo-EM)analysis.The LR comprises eight butterfly-shaped subunits,each containing two symmetric wings.Each wing consists of four elongated,tubular protomers.Within the LR subunit,the eight protomers form a Finger domain,which directly contacts the fusion between the inner and outer nuclear membranes and a Grid domain,which serves as a rigid base for the Finger domain.Two neighboring LR subunits interact with each other through the lateral edges of their wings to constitute a Bumper domain,which displays two major conformations and appears to cushion neighboring NPCs.Our study reveals previously unknown features of the LR and potentially explains the elastic property of the NPC. | Yanqing Zhang Sai Li Chao Zeng Gaoxingyu Huang Xuechen Zhu Qifan Wang Kunpeng Wang Qiang Zhou Chuangye Yan Wusheng Zhang Guangwen Yang Minhao Liu Qinghua Tao Jianlin Lei Yigong Shi | 2020 | Cell Research2020，30，6： | 4 |
| 5 | Finite-element analysis for surface discharge on polyimide insulation in air at atmospheric pressure under pulsed electrical stress显示文摘A surface discharge non-equilibrium plasma model of air–polyimide under pulsed electrical stress is established, byconsidering the reaction of charged particles on the dielectric surface and the secondary electron emission caused by thecondition that high-energy particles bombard the material surface. The model defines the chemical reaction of air discharge byusing simplified set of reactions, which greatly reduces the complexity of the model. To avoid the negative value of particledensity in the process of solution, the logarithmic finite-element method is used to solve the model established, so as toimplement the dynamic simulation of the surface discharge process. Also, the temporal and spatial evolution of themicroparameters such as charge and electric field distribution during discharge are obtained, and the reliability of the model isverified by experiments in terms of discharge development pattern and surface charge accumulation. By comparing thedevelopment process of surface discharge under single pulse and repetitive pulses, it can be seen that surface dischargedevelops from needle electrode to ground electrode under both repetitive pulses and single pulse stress, but the relationshipbetween the discharge propagation time under repetitive pulses and pulse repetition rate is a ‘u’ curve, and the inflection pointmoves to higher repetition rate region with the increase of voltage. | Guojing Dong Qingmin Li Tao Liu Haoyu Gao Minhao Zhang | 2020 | High Voltage2020，5，2： | 2 |

| 10 | Hierarchical Ti_(3)C_(2)T_(x)@MoS_(2) heterostructures:A first principles calculation and application in corrosion/wear protection显示文摘Surface and interface engineering plays a crucial role in modulating the properties of materials,especially two-dimensional(2D)materials.Hence,a strategy,forming heterostructures with MoS_(2),is proposed to overcome the natural agglomeration of Ti_(3)C_(2)T_(x) MXene nanosheets.Most importantly,the interactions between Ti_(3)C_(2)Tx and MoS_(2) were elaborately investigated by first-principles calculations based on density functional theory(DFT)for the first time.The calculations demonstrate that van der Waals forces dominate the interface interactions of Ti_(3)C_(2)T_(x) and MoS_(2),rendering Ti_(3)C_(2)T_(x)@MoS_(2) heterostructures favorable stability.The Ti_(3)C_(2)T_(x)@MoS_(2) heterostructure composites were synthesized through a facile one-step hydrothermal method and exhibit a 2D hierarchical structure.Furthermore,the corrosion and tribological properties of epoxy composite coatings with varying proportions of Ti_(3)C_(2)T_(x)@MoS_(2) composites were studied in detail.As a result,the epoxy composite coating with 0.1 wt.%Ti_(3)C_(2)T_(x)@MoS_(2) composites(Ti_(3)C_(2)T_(x)@MoS_(2)-0.1)exhibits excellent corrosion protection and antiwear performances.The Ti_(3)C_(2)T_(x)@MoS_(2)-0.1 keeps the largest low-frequency impedance modulus(|Z|_(0.)01 Hz)and coating resistance(R_(c))during the whole immersion period.Its wear rate is 0.09μm^(3)/(Nμm)under the load of 10 N,one half of that of pure epoxy coating(EP).This work further broadens the application of MXene-based heterostructure composites. | Meng Cai Peng Feng Han Yan Yuting Li Shijie Song Wen Li Hao Li Xiaoqiang Fan Minhao Zhu | 2022 | Journal of Materials Science & Technology2022，，21： | 1 |
| 11 | Tetrahedral DNA nanostructures synergize with MnO_(2) to enhance antitumor immunity via promoting STING activation and M1 polarization显示文摘Stimulator of interferon genes(STING) is a cytosolic DNA sensor which is regarded as a potential target for antitumor immunotherapy. However, clinical trials of STING agonists display limited anti-tumor effects and dose-dependent side-effects like inflammatory damage and cell toxicity. Here,we showed that tetrahedral DNA nanostructures(TDNs) actively enter macrophages to promote STING activation and M1 polarization in a size-dependent manner, and synergized with Mn^(2+) to enhance the expressions of IFN-β and iNOS, as well as the co-stimulatory molecules for antigen presentation. Moreover, to reduce the cytotoxicity of Mn^(2+),we constructed a TDN-MnO_(2) complex and found that it displayed a much higher efficacy than TDN plus Mn^(2+) to initiate macrophage activation and anti-tumor response both in vitro and in vivo. Together, our studies explored a novel immune activation effect of TDN in cancer therapy and its synergistic therapeutic outcomes with MnO_(2).These findings provide new therapeutic opportunities for cancer therapy. | Siping Liang Jiaying Li Zhengyu Zou Miao Mao Siqi Ming Fan Lin Ziyan Zhang Can Cao Jinyu Zhou Yuanqing Zhang Jiaping Li Minhao Wu | 2022 | Acta Pharmaceutica Sinica B2022，12，5： | 1 |
| 12 | Synergistic lubrication of few-layer Ti_(3)C_(2)T_(x)/MoS_(2) heterojunction as a lubricant additive显示文摘The few-layer Ti_(3)C_(2)T_(x)/MoS_(2) heterostructure was successfully prepared via vertically growing of MoS_(2) nanosheets on the few-layer Ti3C2Tx matrix using hydrothermal method.The tribological properties as additive in mineral oil(150N)were evaluated in detail.The 0.3 wt% of few-layer Ti_(3)C_(2)T_(x)/MoS_(2) heterostructure addition amount can reduce the friction and wear of 150N by 39% and 85%,respectively.Moreover,the enhancement effect of few-layer Ti_(3)C_(2)T_(x)/MoS_(2) on tribological properties of 150N is superior to that of few-layer Ti_(3)C_(2)T_(x),MoS_(2) nanosheets,and their mechanical mixture.Based on the characterization and analysis of wear debris and wear track,such excellent tribological properties of the few-layer Ti_(3)C_(2)T_(x)/MoS_(2) heterostructure derive from its structural advantage toward good dispersion,the synergistic lubrication of Ti_(3)C_(2)T_(x) and MoS_(2) nanosheets during the rubbing process,and the formation of tribo-film. | Peng FENG Yanping REN Yuting LI Jifan HE Zhuang ZHAO Xiaoliang MA Xiaoqiang FAN Minhao ZHU | 2022 | Friction2022，10，12： | 1 |

| 14 | Detector development at the Back-n white neutron source显示文摘Purpose Back-n is a white neutron beamline at China spallation neutron source,which was established in the year of 2018.It is a powerful facility for nuclear data measurement,neutron detector calibration,and radiation effect research.Method A series of detectors were built for different experiments,including beam monitoring,beam profile measurement,neutron induced secondaries(fission fragments,light charged particles and gamma)cross section measurement,and neutron resonance radiography,etc.A common digitization electronics and a cluster-based DAQ were developed for these detector systems.Most detectors have been employed at Back-n and serviced for experiments from the beginning of the beamline running.Results and conclusion As an overview of detectors of Back-n,the details of the detector design and the experiment performing are described in this paper.Some developing systems,e.g.,MTPC and B-MCP,are also included. | Fan Ruirui Li Qiang Bao Jie Li Yang Liu Rong Jiang Wei Ren Jie Zhang Qiwei Cao Ping Gu Minhao Ren Zhizhou Yi Han Tang Jingyu An Qi Bai Haofan Bai Jiangbo Chen Qiping Chen Yonghao Chen Zhen Cui Zengqi Fan Anchuan Feng Changqing Feng Fanzhen Gao Keqing Han Changcai Han Zijie He Guozhu He Yongcheng Hong Yang Hu Yiwei Huang Hanxiong Jia Weihua Jiang Haoyu Jiang Zhijie Jin Zhengyao Kang Ling Li Bo Li Chao Li Gong Li Jiawen Li Xiao Liu Jie Liu Shubin Luan Guangyuan Ning Changjun Qi Binbin Ruan Xichao Song Zhaohui Sun Kang Tan Zhixin Tang Shengda Wang Pengcheng Wang Zhaohui Wen Zhongwei Wu Xiaoguang Wu Xuan Xie Likun Yang Yiwei Yu Yongji Zhang Guohui Zhang Linhao Zhang Mohan Zhang Xianpeng Zhang Yuliang Zhang Yue Zhang Zhiyong Zhao Maoyuan Zhou Luping Zhou Zhihao Zhu Kejun The CSNS Back-n Collaboration | 2023 | Radiation Detection Technology and Methods2023，7，2： | 0 |
| 15 | Towards understanding twinning behavior near fracture surface in magnesium显示文摘Deformation twin is one of the most important strain accommodation mechanisms and ultimately influences the mechanical properties for magnesium and its alloys.Especially,{1011}twin is usually thought to be closely related to the fracture or fatigue process of magnesium alloys.In the present work,the characteristics of microstructure near fracture region of deformed magnesium alloy have been investigated by a combination of electron back-scatter diffraction(EBSD)and transmission electron microscope(TEM).It has found that a large of deformation twins occur near fraction region,including{1012}and{1011}primary twins,{1011}-{1012}double twin and{1011}-{1012}-{1011}-{1012}quadruple twin.The actual boundaries of{1011}twins at atomic scale consist of{1011}coherent twinning boundaries(TBs)and parallel basal-pyramidal(BPy/Py B)planes.The tip of{1011}twin can even end up with BPy/Py B interfaces only.The experimental observations also reveal that when two{1011}twin variants sharing a common[1120]zone axis approach each other,the growth of one twin is usually hindered by the boundaries of the other twin.In addition,an apparent'crossing'phenomenon is also discovered when interaction of two{1011}twins takes place.According to these experimental observations,the possible underlying mechanisms behind such phenomena are proposed and discussed.These finding are expected to provide an insight into understanding the twinning behavior and the relationship between twin and fracture in magnesium and other materials with hexagonal structure. | Hao Li Qinghui Zeng Pengfei Yang Qi Sun Jianmin Wang Jian Tu Minhao Zhu | 2020 | Journal of Materials Science & Technology2020，36，8： | 0 |
| 16 | Insights into the tribological behavior of choline chloride-urea and choline chloride-thiourea deep eutectic solvents显示文摘Deep eutectic solvents(DESs)have been considered as novel and economic alternatives to traditional lubricants because of their similar physicochemical performance.In this study,choline chloride(ChCl)DESs were successfully synthesized via hydrogen-bonding networks of urea and thiourea as the hydrogen bond donors(HBDs).The as-synthesized ChCl-urea and ChCl-thiourea DESs had excellent thermal stability and displayed good lubrication between steel/steel tribo-pairs.The friction coefficient and wear rate of ChCl-thiourea DES were 50.1%and 80.6%,respectively,lower than those of ChCl-urea DES for GCr15/45 steel tribo-pairs.However,for GCr15/Q45 steel,ChCl-urea DES decreased the wear rate by 85.0%in comparison to ChCl-thiourea DES.Under ChCl-thiourea DES lubrication,the tribo-chemical reaction film composed of FeS formed at the interfaces and contributed to low friction and wear.However,under high von Mises stress,the film could not be stably retained and serious wear was obtained through direct contact of friction pairs.This illustrated that the evolution of the tribo-chemical reaction film was responsible for the anti-friction and anti-wearproperties of the DESs. | Yuting LI Yuan LI Hao LI Xiaoqiang FAN Han YAN Meng CAI Xiaojun XU Minhao ZHU | 2023 | Friction2023，11，1： | 0 |
| 17 | Lipid-conjugated siRNA hitchhikes endogenous albumin for tumor immunotherapy显示文摘With the development of a small interfering RNA(siRNA)delivery strategy,increasing siRNA therapeutics for tumor treatment appeared in clinical trials and pre-clinical development.However,the test results of such therapeutics unveiled that efficient siRNA delivery to tumor tissues is still challenging.Albumin is considered an ideal carrier for delivering hydrophobic agents into tumor tissue because it is highly concentrated and long-circulating in blood and has propensity of tumor enrichment.Herein,we synthesized lipid conjugated siRNAs(LsiRNAs),which showed high affinity to albumin.Mechanistically,LsiRNAs non-covalently bind to the hydrophobic core of albumin through its octadecyl tails.The small size of albumin/LsiRNAs allows the complex to penetrate tumor tissue efficiently.Biodistribution test proved that albumin extremely prolonged circulation time and increased tumor retention of associated LsiRNAs.Notably,LsiRNA against programmed death ligand-1(Pdl1)efficiently suppressed tumor growth as well as prolonged survival time of tumor bearing mice by increasing infiltration of CD8^(+)T cells as well as promoted the maturation of dendritic cells both in tumor and lymph.Together,LsiRNAs provide a simple but effective way for siRNA tumor delivery that“hitchhikes”on albumin. | Bo Hu Sudong Kong Yuhua Weng Deyao Zhao Abid Hussain Qingze Jiao Shijing Zhan Ling Qiu Jianguo Lin Minhao Xie Bo Li Yuanyu Huang | 2023 | Chinese Chemical Letters2023，34，11： | 0 |
| 18 | Well-Dispersed Graphene Enhanced Lithium Complex Grease Toward High-Efcient Lubrication显示文摘Graphene as a lubricating additive holds great potential for industrial lubrication. However, its poor dispersity and compatibility with base oils and grease hinder maximizing performance. Here, the infuence of graphene dispersion on the thickening efect and lubrication function is considered. A well-dispersed lubricant additive was obtained via trihexyl tetradecyl phosphonium bis(2-ethylhexyl) phosphate modifed graphene ([P_(66614)][DEHP]-G). Then lithium complex grease was prepared by saponifcation with 12-OH stearic acid, sebacic acid, and lithium hydroxide, using polyalphaolefn (PAO20) as base oil and the modifed-graphene as lubricating additive, with the original graphene as a comparison. The physicochemical properties and lubrication performance of the as-prepared greases were evaluated in detail. The results show that the as-prepared greases have high dropping point and colloidal stability. Furthermore, modifed-graphene lithium complex grease ofered the best friction reduction and anti-wear abilities, manifesting the reduction of friction coefcient and wear volume up to 18.84% and 67.34%, respectively. With base oil overfow and afux, well-dispersed [P_(66614)][DEHP]-G was readily adsorbed to the worn surfaces, resulting in the formation of a continuous and dense graphene deposition flm. The synergy of deposited graphene-flm, spilled oil, and adhesive grease greatly improves the lubrication function of grease. This research paves the way for modulating high-performance lithium complex grease to reduce the friction and wear of movable machinery. | Kaiyue Lin Zhuang Zhao Yuting Li Zihan Zeng Xiaofeng Wei Xiaoqiang Fan Minhao Zhu | 2023 | Chinese Journal of Mechanical Engineering2023，36，5： | 0 |
| 19 | Micro‐mechanism study on synergistic degradation of the oil‐paper insulation with dibenzyl disulfide,hexadecyl mercaptan and benzothiophene显示文摘In recent years,there have been many cases of transformer failures caused by corrosive sulfides.At present,research mainly focuses on the single sulfide dibenzyl disulphide,but few research on multiple sulphur or the oil‐paper hybrid insulation.In this study,three typical sulfides dibenzyl disulfide,hexadecyl mercaptan and benzothiophene were selected to form seven sulfide‐oil‐paper models.Then relaxation calculations were carried out,and through molecular dynamics simulation,the synergistic effect of different sulfides on the properties of insulating paper and insulating oil was discussed.Results show that the coexistence of the three sulfides has the most severe weakening on the mechanical properties of cellulose,and it also causes great damage to hydrogen bonds.Hexadecyl mercaptan has a weaker effect on hydrogen bond destruction,but it will greatly aggravate the cellulose chain movement.The viscosity of insulating oil is generally increased by the influence of sulfide.Hexadecyl mercaptan is the main factor affecting the viscosity.Thiophene has little effect on the viscosity,ctive protection technology on sulphur corrosion. | Haoxi Cong Hao Pan Xuefeng Hu Minhao Zhang Qingmin Li | 2021 | High Voltage2021，6，3： | 0 |
| 20 | Insight into the structure-capacity relationship in biomass derived carbon for high-performance sodium-ion batteries显示文摘Carbonaceous materials are the most promising candidates as the anode for sodium-ion batteries (SIBs), however, they still suffer from low electric conductivity and sluggish sodium ion (Na+) reaction kinetics. Appropriate composition modulation using heteroatoms doping and structure optimization is highly desired. A basic empirical understanding of the structure-capacity relationship is also urgent in tackling the above problems. Herein, multi-functional nitrogen (N) doped carbon micro-rods with enlarged interlayer spacing are synthesized and investigated as the anode in SIBs, showing an ultra-stable capacity of 161.5 mAh g^(−1) at 2 A g^(−1) for over 5000 cycles. Experimental investigations and first-principle calculations indicate that the enlarged interlayer spacing can facilitate Na+ intercalation and N doping can guarantee the high electric conductivity and favorable electrochemical active sites. Additionally, pyridinic N is theoretically proved to be more effective to enhance Na+ adsorption than pyrrolic N due to the lower adsorption energy and stronger binding energy with Na+. Full SIBs show a high capacity and cyclability, making the biomass-derived carbon micro-rods to be a promising anode for practical SIBs applications. | Jianguo Sun Yao Sun Jin An Sam Oh Qilin Gu Weidong Zheng Minhao Goh Kaiyang Zeng Yuan Cheng Li Lu | 2021 | Journal of Energy Chemistry2021，30，11： | 0 |
