| 1 | Cenozoic sedimentary records and geochronological constraints of differential uplift of the Qinghai-Tibet Plateau显示文摘Geological mapping data (1:250000) in the Qinghai-Tibet Plateau and its adjacent regions reveal the sediment sequences, distribution and tectonic evolution of the 92 Tertiary remnant basins. Southern Tibet and the Yecheng area in Xinjiang, located at southern and northwestern margins of the Qinghai-Tibet Plateau, respectively, were parts of the Neo-Tethys remnant sea in the Paleogene. In southern Tibet, both the subabyssal and abyssal sequences occur at the Gyangze, Saga, Guoyala, and Sangmai areas. The deep-water facies successions outcrop in the west, whereas the shallow-water facies sequences in the east, indicating the east to the west retreat of the Neo-Tethys Ocean. The retreat of the Neo-Tethys Ocean in the east was contributed to the earlier tectonic uplift of the eastern Qinghai-Tibet Plateau. The uplift process of the Plateau from the Late Cretaceous to Pliocene is described as follows: During the Late Cretaceous, tectonic uplift of the Qinghai-Tibet Plateau occurred in the northeastern part and the configuration of the Qinghai-Tibet Plateau was characterized by rise in the northeast and depression in the west. In the Paleocene-Eocene interval, the Tengchong-Baingoin and Kuyake-Golmud areas experienced local tectonic uplifting, the West Kunlun uplift zone broadened easterly, the Qilian uplift zone broadened southerly, and the Songpan-Garzê uplift zone shrank easterly. The Oligocene configuration of the Qinghai-Tibet Plateau was characterized by mountain chains rising along its margins and sedimentary basins in the central part because of tectonic uplifts of the Gangdisê and the Himalaya blocks. Meanwhile, the Kunlun-Altyn-Qilian uplift zones have also broadened southerly and northerly. In contrast, the great uplift zones of the Gangdisê, the Himalaya, the Karakorum, and the Kunlun blocks characterize the paleogeographic contours of the Qinghai-Tibet Plateau during the Miocene-Pliocene. Additionally, the thermochronological data on tectonic uplift events in southern Tibet, West Kunlun Mountains, Altyn Tagh, eastern Tibet, and western Sichuan all suggest that the most intense deformation occurred at 13-8 Ma and since 5 Ma, respectively, corresponding to two great uplift periods in Neogene. As a result, turnover of paleogeographic configuration of the Qinghai-Tibet Plateau occurred during the Neogene, experiencing a change from high contours in the east in the pre-Oligocene to high contours in the west at the end-Pliocene. The uplift of the Qinghai-Tibet Plateau during the Cenozoic was episodic, and the uplifts of various blocks within the Plateau were spatially and chronologically different. | ZHANG KeXin WANG GuoCan CAO Kai LIU Chao XIANG ShuYuan HONG HanLie KOU XiaoHu XU YaDong CHEN FenNing MENG YanNing CHEN RuiMing | 2008 | Science China Earth Sciences2008，51，11： | 31 |

| 3 | Optimization of mechanical property, antibacterial property and corrosion resistance of Ti-Cu alloy for dental implant显示文摘Ti-Cu alloys with different Cu contents(3, 5 and 7 wt%) were fabricated and studied as novel antibacterial biomaterials for dental application. The Ti-Cu alloys were annealing treated at different temperatures(740℃, 830℃ and 910℃) in order to obtain three typical microstructures, β-Ti + Ti2Cu, β-Ti + transformed α-Ti, and transformed α-Ti. Mechanical, antibacterial and biocorrosion properties of Ti-Cu alloys with different microstructures were well analyzed by scanning electron microscopy(SEM),X-ray diffraction(XRD), transmission electron microscopy(TEM), tensile test, electrochemical test and antibacterial test. The results indicated that the Ti-Cu alloys with microstructure of β-Ti + Ti2 Cu showed the best ductility compared with other Ti-Cu alloys with microstructures of β-Ti + transformed α-Ti and complete transformed α-Ti, and meanwhile, increase of the Cu content significantly contributed to the decreased ductility due to the increasing amount of Ti2 Cu, which brought both solid solution strengthening and precipitation strengthening. Finally, the Ti-5 Cu alloy with microstructure of β-Ti + Ti2 Cu exhibited excellent ductility, antibacterial property and corrosion resistance, providing a great potential in clinical application for dental implants. | Jiewen Wang Shuyuan Zhang Ziqing Sun Hai Wang Ling Ren Ke Yang | 2019 | Journal of Materials Science & Technology2019，35，10： | 9 |
| 4 | Dynamic-Change Laws of the Porosity and Permeability of Low-to Medium-Rank Coals under Heating and Pressurization Treatments in the Eastern Junggar Basin,China显示文摘Deep coalbed methane exists in high-temperature and high-pressure reservoirs. To elucidate the dynamic-change laws of the deep coal reservoir porosity and permeability characteristics in the process of coalbed methane production, based on three pieces of low-to medium-rank coal samples in the eastern Junggar Basin, Xinjiang, we analyse their mercury-injection pore structures. We measured the porosity and permeability of the coal samples at various temperatures and confining pressures by high-temperature and confining pressure testing. The results show that the porosity of a coal sample decreases exponentially with increasing effective stress. With increasing temperature, the initial porosity increases for two pieces of relatively low-rank coal samples. The increased rate of porosity decreases with increasing confining pressure. With increasing temperature, the initial porosity of a relatively high-rank coal sample decreases, and the rate of change of the porosity become faster. An exponential relationship exists between the porosity and permeability. With increasing coal rank, the initial porosity and permeability decrease. The change rate of the permeability decreases with increasing porosity. | Gang Wang Yong Qin Jian Shen Shuyuan Chen Beibei Han Xiaoting Zhou | 2018 | Journal of Earth Science2018，29，3： | 8 |
| 5 | 3-year Treatment of Tenofovir Alafenamide vs.Tenofovir Disoproxil Fumarate for Chronic HBV Infection in China显示文摘Background and Aims:Tenofovir alafenamide(TAF)has similar efficacy to tenofovir disoproxil fumarate(TDF)but with improved renal and bone safety in chronic hepatitis B patients studied outside of China.We report 3-year results from two phase 3 studies with TAF in China(Clinicaltrials.gov:NCT02836249 and NCT02836236).Methods:Chinese hepatitis B e antigen(HBeAg)-positive and-negative chronic hepatitis B patients with viremia and elevated alanine aminotransferase were randomized 2:1 to TAF or TDF treatment groups and treated in a double-blind fashion for 144 weeks(3 years).Efficacy responses were assessed by individual study while safety was assessed by a pooled analysis.Results:Of the 334 patients(180 HBeAg-positive and 154 HBeAg-negative)randomized and treated,baseline characteristics were similar between groups.The overall mean age was 38 years and 73%were male.The mean HBV DNA was 6.4 log10 IU/mL.The median alanine aminotransferase was 88 U/L,and 37%had a history of antiviral use.At week 144,the proportion with HBV DNA<29 IU/mL was similar among the two groups,with TAF at 83%vs.TDF at 79%,and TAF at 93%vs.TDF at 92%for the HBeAg-positive and-negative patients,respectively.In each study,higher proportions of TAF than TDF patients showed normalized alanine aminotransferase(via the American Association for the Study of Liver Diseases and the China criteria)and showed loss of HBsAg;meanwhile,the HBeAg seroconversion rates were similar.Treatment was well-tolerated among the TAF patients,who showed a smaller median decline in creatinine clearance(−0.4 vs.−3.2 mL/min;p=0.014)and less percentage change in bone mineral density vs.TDF at hip(−0.95%vs.−1.93%)and spine(+0.35%vs.−1.40%).Conclusions:In chronic hepatitis B patients from China,TAF treatment provided efficacy similar to TDF but with better renal and bone safety at 3 years. | Jinlin Hou Qin Ning Zhongping Duan You Chen Qing Xie Fu-Sheng Wang Lunli Zhang Shanming Wu Hong Tang Jun Li Feng Lin Yongfeng Yang Guozhong Gong John FFlaherty Anuj Gaggar Shuyuan Mo Cong Cheng Gregory Camus Chengwei Chen Yan Huang Jidong Jia Mingxiang Zhang GS-US-320-0110 and GS-US-320-0108 China Investigators | 2021 | Journal of Clinical and Translational Hepatology2021，9，3： | 7 |
| 6 | Possibility of the Application of the Ultra-long Electromagnetic Wave Remote Sensor to Marine Geological Exploration显示文摘The ultra-long electromagnetic wave remote sensing technique developed by Peking University is one of new future techniques, which can detect the submarine geological information from the depth of 20 to 10000 m below the surface by receiving natural ultra-long electromagnetic waves (n Hz to n 100 Hz). The new remote sensor is composed of three parts: a main instrument with a portable computer, an antenna with an amplifier and an external power.The new remote sensing technique is characterized by good stability and reproducibility at the same spot but at different times and high sensitivity and high signal-to-noise ratio, and can reveal geological and lithologic boundaries as well as strata and related mineral sources. Two years of marine geological experiments on this technique have indicated that it can solve many problems in marine geological exploration, e.g. the burial depths of sea-floor mud, Quaternary sediments and submarine structures. This technique can be applied to detecting the sea bed | HOU Guiting QIAN Xianglin WANG Shuyuan SUN Jing | 2000 | Acta Geologica Sinica(English Edition)2000，74，2： | 6 |
| 7 | Effect of CO_2 Gas on the Swelling and Tribological Behaviors of NBR Rubber in Water显示文摘The swelling and tribological behaviors of nitrile-butadience(NBR) rubbers with three acrylonitrile contents(N18,N26 and N41) in water with different CO_2 gas flows are investigated by immersion and wear experiments.The results show that the bubbles of CO_2 into water severely destroy the cross-linking network of rubber and form defects on the surface,such as cracks,holes and lamellar perks.These defects lead to an increase in the static and dynamic swelling increment.The dynamic swelling increment is almost three or four times larger than the static swelling increment.The hardness and wear resistance of rubbers in water with CO_2 gas remarkably decreases in contrast to that in water,and they gradually decrease with an increase in the gas flow in water.The bubbles of CO_2 decrease the steady frictional coefficient of rubber in water due to the presence of the gas in water lubricant film.The steady frictional coefficient in water with different CO_2 gas flow basically remains 0.1.N41 with high acrylonitrile content shows better swelling and wear resistances than N18 and N26 because of its dense molecular network. | Xiaoren Lv Shuyuan Song Huiming Wang Shijie Wang | 2015 | Journal of Materials Science & Technology2015，31，12： | 6 |
| 8 | Near-surface wind environment in the Yarlung Zangbo River basin,southern Tibetan Plateau显示文摘Aeolian processes have been studied extensively at low elevations,but have been relatively little studied at high elevations.Aeolian sediments are widely distributed in the Yarlung Zangbo River basin,southern Tibetan Plateau,which is characterized by low pressure and low temperature.Here,we comprehensively analyzed the wind regime using data since 1980 from 11 meteorological stations in the study area,and examined the interaction between the near-surface wind and aeolian environment.The wind environment exhibited significant spatial and temporal variation,and mean wind speed has generally decreased on both annual and seasonal bases since 1980,at an average of 0.181 m/(s•10a).This decrease resulted from the reduced contribution of maximum wind speed,and depended strongly on variations of the frequency of sand-driving winds.The drift potential and related parameters also showed obvious spatial and temporal variation,with similar driving forces for the wind environment.The strength of the wind regime affected the formation and development of the aeolian geomorphological pattern,but with variation caused by local topography and sediment sources.The drift potential and resultant drift direction were two key parameters,as they quantify the dynamic conditions and depositional orientation of the aeolian sediments.Wind affected the spatial variation in sediment grain size,but the source material and complex topographic effects on the near-surface wind were the underlying causes for the grain size distribution of aeolian sands.These results will support efforts to control aeolian desertification in the basin and improve our understanding of aeolian processes in high-elevation environments. | YANG Junhuai XIA Dunsheng WANG Shuyuan TIAN Weidong MA Xingyue CHEN Zixuan GAO Fuyuan LING Zhiyong DONG Zhibao | 2020 | Journal of Arid Land2020，12，6： | 5 |
| 9 | Pyrolysis characteristics of a North Korean oil shale显示文摘Pyrolysis characteristics of a North Korean oil shale and its pyrolysates were investigated in this paper. The pyrolysis experiments were conducted below 600 °C at a heating rate of 10, 15, 20 and 25 °C/min, respectively. The kinetics data were calculated using both integral and differential methods with the assumption of first order kinetics. The results show that the averaged oil content of the North Korean oil shale is about 12.1 wt% and its heat value is 13,400 kJ/kg. The oil yields at different retorting temperatures show that the higher the retorting temperature the greater the oil and retorting gas yields. The optimal retorting temperature for the North Korean oil shale is about 500 oC. The properties of the North Korean shale oil including density, viscosity, flash point and freezing point are found to be relatively low compared with those of shale oil from FuShun, China. The gasoline fraction, diesel fraction and heavy oil fraction account for 11.5 wt%, 41.5 wt% and 47 wt%, respectively. The major pyrolysis gases are CH4(the most abundant), H2, CO2, H2 S, CO, and C2-C5 hydrocarbons. The heat value of retorting gas is more than 900 kJ/mol, and the retorting gas has high sulfur content. | Wang Wei Li Shuyuan Li Linyue Ma Yue Yue Changtao He Jilai | 2014 | Petroleum Science2014，11，3： | 4 |
| 10 | Structural basis for bivalent binding and inhibition of SARS-CoV-2 infection by human potent neutralizing antibodies显示文摘Neutralizing monoclonal antibodies(nAbs)to severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)represent promising candidates for clinical intervention against coronavirus disease 2019(COVID-19).We isolated a large number of nAbs from SARS-CoV-2-infected individuals capable of disrupting proper interaction between the receptor binding domain(RBD)of the viral spike(S)protein and the receptor angiotensin converting enzyme 2(ACE2).However,the structural basis for their potent neutralizing activity remains unclear.Here,we report cryo-EM structures of the ten most potent nAbs in their native full-length IgG-form or in both IgG-form and Fab-form bound to the trimeric S protein of SARS-CoV-2.The bivalent binding of the full-length IgG is found to associate with more RBDs in the“up”conformation than the monovalent binding of Fab,perhaps contributing to the enhanced neutralizing activity of IgG and triggering more shedding of the S1 subunit from the S protein.Comparison of a large number of nAbs identified common and unique structural features associated with their potent neutralizing activities.This work provides a structural basis for further understanding the mechanism of nAbs,especially through revealing the bivalent binding and its correlation with more potent neutralization and the shedding of S1 subunit. | Renhong Yan Ruoke Wang Bin Ju Jinfang Yu Yuanyuan Zhang Nan Liu Jia Wang Qi Zhang Peng Chen Bing Zhou Yaning Li Yaping Shen Shuyuan Zhang Long Tian Yingying Guo Lu Xia Xinyue Zhong Lin Cheng Xiangyang Ge Juanjuan Zhao Hong-Wei Wang Xinquan Wang Zheng Zhang Linqi Zhang Qiang Zhou | 2021 | Cell Research2021，31，5： | 4 |
| 11 | Biodegradable magnesium alloy WE43 porous scaffolds fabricated by laser powder bed fusion for orthopedic applications:Process optimization,in vitro and in vivo investigation显示文摘Laser powder bed fusion(L-PBF)of magnesium(Mg)alloy porous scaffolds is expected to solve the dual challenges from customized structures and biodegradable functions required for repairing bone defects.However,one of the key technical difficulties lies in the poor L-PBF process performance of Mg,contributed by the high susceptibility to oxidation,vaporization,thermal expansion,and powder attachment etc.This work investigated the influence of L-PBF energy input and scanning strategy on the formation quality of porous scaffolds by using WE43 powder,and characterized the microstructure,mechanical properties,biocompatibility,biodegradation and osteogenic effect of the as-built WE43 porous scaffolds.With the customized energy input and scanning strategy,the relative density of struts reached over 99.5%,and the geometrical error between the designed and the fabricated porosity declined to below 10%.Massive secondary phases including intermetallic precipitates and oxides were observed.The compressive strength(4.37-23.49 MPa)and elastic modulus(154.40-873.02 MPa)were comparable to those of cancellous bone.Good biocompatibility was observed by in vitro cell viability and in vivo implantation.The biodegradation of as-built porous scaffolds promoted the osteogenic effect,but the structural integrity devastated after 12 h by the immersion tests in Hank’s solution and after 4 weeks by the implantation in rabbits’femur,indicating an excessively rapid degradation rate. | Jinge Liu Bingchun Liu Shuyuan Min Bangzhao Yin Bo Peng Zishi Yu Caimei Wang Xiaolin Ma Peng Wen Yun Tian Yufeng Zheng | 2022 | Bioactive Materials2022，7，10： | 4 |

| 13 | Depositional System of the Carboniferous Huanglong Formation,Eastern Sichuan Basin:Constraints from Sedimentology and Geochemistry显示文摘Using analyses of the lithology,sequences,paleoenvironment,and tectonic setting,the depositional system of the Carboniferous Huanglong Formation in the eastern Sichuan Basin was identified.The lithological characteristics of the Lower Member,Middle Member,and Upper Member were analyzed and classified.Before the use of carbon,oxygen,and strontium isotopes in the analysis,all of the geochemical data were tested for validity.On the basis of the Z values obtained from carbon and oxygen isotopes,the paleoenvironments of the three members were elucidated.Lower Member was dominantly an enclosed marine environment with intense evaporation and little freshwater input into the sea.Middle Member developed in a semi-enclosed to normal marine environment with many rivers.Upper Member was formed in a normal marine environment.The east Sichuan Basin was enclosed by paleouplifts before the deposition of the Huanglong Formation,forming a relatively enclosed depositional setting.Paleogullies developed in the Silurian strata that underlie the Carboniferous rocks;these paleogullies can be identified.On the basis of a comprehensive analysis,we propose that the Huanglong Formation developed in a platform system.Four microfacies were identified:supratidal flat,dolostone flat,grain shoal,and shelf microfacies.The high-permeability and high-porosity characteristics of the grain shoal microfacies are favorable for hydrocarbon accumulation,while the supratidal flat and shelf microfacies developed very few high-quality reservoirs.The paleogullies,in which increased amounts of grain shoal microfacies developed,controlled the distribution of high-quality reservoirs. | WANG Kun HU Suyun LI Wei LIU Wei HUANG Qingyu MA Kui SHI Shuyuan | 2016 | Acta Geologica Sinica(English Edition)2016，90，5： | 3 |

| 15 | Effect of Different Factors on Nitrogen Removal Rate in Constructed Wetlands显示文摘Factors affecting total nitrogen(TN) removal rates in constructed wetland were investigated by intermittent operation in the subsurface flow(SSF) constructed wetland system.The results demonstrated that removal rates of TN increased with the rising of TN pollution load(1.40-12.40 g/m2) when the retention time was determined by 60% TN removal efficiency(n=180,p<0.05) in SSF wetlands.The maximum TN removal rate was 1.71 g/(m2·d) in SSF Phragmites australis-soil-slag system.TN removal rates were affected by total phosphorus load in case of higher TN load.TN removal rates in SSF Phragmites australis wetlands were greater than that in SSF Calamagrostis angustifolia wetlands at the same experimental cycle.Effect of wetland substrates on TN removal rates varied with the pollutants loading in SSF constructed wetland system,plant species and plant-growing period. | LIU Shuyuan YAN Baixing WANG Lixia | 2010 | 湿地科学2010，8，2： | 3 |
| 16 | Bi Nanoparticles Anchored in N-Doped Porous Carbon as Anode of High Energy Density Lithium Ion Battery显示文摘A novel bismuth–carbon composite, in which bismuth nanoparticles were anchored in a nitrogen-doped carbon matrix(Bi@NC), is proposed as anode for high volumetric energy density lithium ion batteries(LIBs).Bi@NC composite was synthesized via carbonization of Zn-containing zeolitic imidazolate(ZIF-8) and replacement of Zn with Bi, resulting in the N-doped carbon that was hierarchically porous and anchored with Bi nanoparticles. The matrix provides a highly electronic conductive network that facilitates the lithiation/delithiation of Bi.Additionally, it restrains aggregation of Bi nanoparticles and serves as a buffer layer to alleviate the mechanical strain of Bi nanoparticles upon Li insertion/extraction.With these contributions, Bi@NC exhibits excellent cycling stability and rate capacity compared to bare Bi nanoparticles or their simple composites with carbon. This study provides a new approach for fabricating high volumetric energy density LIBs. | Yaotang Zhong Bin Li Shumin Li Shuyuan Xu Zhenghui Pan Qiming Huang Lidan Xing Chunsheng Wang Weishan Li | 2018 | Nano-Micro Letters2018，10，4： | 3 |
| 17 | Effects of surface roughening on antibacterial and osteogenic properties of Ti-Cu alloys with different Cu contents显示文摘In order to reduce implant-related infections and improve early osseointegration,we performed HF+anodic oxidation on the surface of the new antibacterial Ti-Cu alloy to make the titanium-based implants have a micro/submicron structure.On this basis,a series of surface-modified Ti-x Cu alloys with different Cu contents(3,5 and 7 wt%)were fabricated and a comprehensive study was conducted on MC3 T3-E1 cell adhesion,proliferation,apoptosis and its antibacterial activity against Staphylococcus aureus.Results showed that the Ti-x Cu alloys by HF etching+anodized possessed multifunctional characteristics of antibiofilm and antibacterial abilities,excellent biocompatibility and osteogenesis promoting abilities.Increment of Cu content significantly contributed to the antibacterial and osteogenic properties of HF etching+anodized Ti-Cu alloys.Cell proliferation rates of HF etching+anodized Ti-7 Cu alloys were lower than those of Ti-3 Cu and Ti-5 Cu alloys,while the early cell apoptosis rates were higher than Ti-3 Cu and Ti-5 Cu groups.All the above results finally presented that the HF etching+anodized Ti-5 Cu alloy exhibited extremely strong antibacterial properties,good biological compatibility and osteogenic ability,as well as the most excellent ductility and corrosion resistance,providing a great potential application for the future dental implantation. | Wei Zhang Shuyuan Zhang Hui Liu Ling Ren Qiang Wang Yang Zhang | 2021 | Journal of Materials Science & Technology2021，，29： | 3 |

| 19 | Study on Property of Salicylaldehyde Schiff Base Metal Complexes for Catalytic Oxidation of Model Sulfides显示文摘Seven kinds of Schiff base metal complexes(C1-C7)were synthesized by the reaction of substituted salicylaldehyde Schiff base with cobalt nitrate,nickel nitrate,and copper nitrate,respectively.The oxygen carrying performance,and the catalytic property of complexes for the oxidation of model sulfides 1-hexanethiol,dibutyl sulfide,and 2-methylthiophene along with their influencing factors were explored,while the oxidized products of the model sulfides were also analyzed and characterized.The results show that the catalytic oxidation property of the complexes is determined by their oxygen carrying performance and solubility in n-octane.The oxygen carrying performance of the complexes is mainly affected by the central ion species,the electronic effects,and the spatial effects of the substituents as well as the degree of conjugation.More specifically,the oxygen carrying performance can be improved by enhancing the oxygenation capacity of the central metal ions,increasing the electron donating ability of the ligand substituent,and diminishing the steric hindrance as well as extending the conjugated chain.Complexes C7 were found to be with high oxygen carrying capacity and high solubility in n-octane,which shows the best catalytic oxidation property,and the oxidation conversion rates for 1-hexylthiol,dibutyl sulfide,and 2-methylthiophene are 74.2%,65.1%,and 22.7%,respectively.Upon using the oxidation catalyst of Schiff base metal complexes,three sulfides can be oxidized by oxygen to form sulfones and sulfoxides.1-Hexanethiol and dibutyl sulfide will continue to be oxidized to form sulfates and sulfites. | Jia Chaoyang Liang Shuyuan Liu Lei Shao Xue Zhang Longli Wang Fangzhu Jiang Cuiyu | 2021 | China Petroleum Processing & Petrochemical Technology2021，23，1： | 2 |
| 20 | Preliminary study of microstructure, mechanical properties and corrosion resistance of antibacterial Ti-15Zr-xCu alloy for dental application显示文摘Ti-15 Zr-xCu(3≤x≤7,wt.%) novel antibacterial and antibiofilm alloys with competitive mechanical properties,biological responses and corrosion resistance were designed and fabricated.Annealing heat treatment on Ti-15 Zr-7 Cu(TZC-7 A),after holding for 2 h at slightly above their beta transus temperature(BTT) ensured their tensile strength(UTS),yield strength(YS) and hardness(HRV) were improved by31.2%,20% and 12.3% respectively compared to the control without Cu,Ti-15 Zr(T-15 ZA).Although the3 wt.% Cu alloy displayed the highest elongation(26%),the TZC-7 A alloy also possessed a good ductility.Presence of evenly dispersed Ti2 Cu and Zr2 Cu Cu-rich intermetallic phases formed as interwoven and alternating lamellae within the α+β matrix as a result of Cu addition,as revealed by X-ray diffraction(XRD),scanning electron microscopy(SEM) and transmission electron microscopy(TEM).These greatly contributed to their strengthening and bactericidal properties.Over 98% antibacterial effect against E.coli and S.aureus have been imparted,coupled with excellent biofilm inhibition.Potentiodynamic polarization curves showed that the TZC-7 A alloy possessed higher corrosion resistance than commercially pure titanium,cp-Ti;contact angle test revealed enhanced hydrophilicity;while confocal laser scanning microscopy(CLSM) and cell counting kit(CCK-8) assays also displayed drastically lowered bacterial adhesion rate with comparatively no cytotoxicity.Cell attachment on all alloys was similar but the best spread was obtained on TZC-7 A after 24 h.The developed alloy has good potential as an antibacterial implant material with combination of optimized properties. | Sharafadeen Kunle Kolawole Wang Hai Shuyuan Zhang Ziqing Sun Muhammad Ali Siddiqui Ihsan Ullah Wei Song Frank Witte Ke Yang | 2020 | Journal of Materials Science & Technology2020，47，15： | 2 |
