| 1 | Biodegradable Zn–3Cu and Zn–3Cu–0.2Ti alloys with ultrahigh ductility and antibacterial ability for orthopedic applications显示文摘Zinc(Zn) and its alloys have been proposed as biodegradable implant materials due to their unique combination of biodegradability, biocompatibility, and biofunctionality. However, the insufficient mechanical properties of pure Zn greatly limit its clinical application. Here, we report on the microstructure, mechanical properties, friction and wear behavior, corrosion and degradation properties, hemocompatibility, and cytocompatibility of Zn–3 Cu and Zn–3 Cu–0.2 Ti alloys under three different conditions of as-cast(AC),hot-rolling(HR), and hot-rolling plus cold-rolling(HR + CR). The HR + CR Zn–3 Cu–0.2 Ti exhibited the best set of comprehensive properties among all the alloy samples, with yield strength of 211.0 MPa, ultimate strength of 271.1 MPa, and elongation of 72.1 %. Immersion tests of the Zn–3 Cu and Zn–3 Cu–0.2 Ti alloys in Hanks’ solution for 3 months indicated that the AC samples showed the lowest degradation rate,followed by the HR samples, and then the HR + CR samples, while the HR + CR Zn–3 Cu exhibited the highest degradation rate of 23.9 m/a. Friction and wear testing of the Zn–3 Cu and Zn–3 Cu–0.2 Ti alloys in Hanks’ solution indicated that the AC samples showed the highest wear resistance, followed by the HR samples, and then the HR + CR samples, while the AC Zn–3 Cu–0.2 Ti showed the highest wear resistance.The diluted extracts of HR + CR Zn–3 Cu and Zn–3 Cu–0.2 Ti at a concentration of ≤25 % exhibited noncytotoxicity. Furthermore, both the HR + CR Zn–3 Cu and Zn–3 Cu–0.2 Ti exhibited effective antibacterial properties against S. aureus. | Jixing Lin Xian Tong Kun Wang Zimu Shi Yuncang Li Matthew Dargusch Cuie Wen | 2021 | Journal of Materials Science & Technology2021，，9： | 3 |
| 2 | Manufacturing of graded titanium scaffolds using a novel space holder technique显示文摘To optimize both the mechanical and biological properties of titanium for biomedical implants,a highly flexible powder metallurgy approach is proposed to generate porous scaffolds with graded porosities and pore sizes.Sugar pellets acting as space holders were compacted with titanium powder and then removed by dissolution in water before sintering.The morphology,pore structure,porosity and pore interconnectivity were observed by optical microscopy and SEM.The results show that the porous titanium has porosity levels and pore size gradients consistent with their design with gradual and smooth transitions at the interfaces between regions of differing porosities and/or pore sizes.Meanwhile,the porous titanium has high interconnectivity between pores and highly spherical pore shapes.In this article we show that this powder metallurgy processing technique,employing the novel sugar pellets as space-holders,can generate porous titanium foams with well-controlled graded porosities and pore sizes.This method has excellent potential for producing porous titanium structures for hard tissue engineering applications. | Yunhui Chen Damon Kent Michael Bermingham Ali Dehghan-Manshadi Gui Wang Cuie Wen Matthew Dargusch | 2017 | Bioactive Materials2017，2，4： | 2 |
| 3 | Gene mapping of a new coat mutation in mouse显示文摘Gene mapping of a mouse coat mutation has been investigated. First, 100 10-bp random primers were used to amplify DNA, but the mutation could not be located by this method because there were no correlation between the amplified products and coat phenotypes. Second, by using ldh1 , Car2, Mup1 , Pgb1 , Hbb, Es1O, Es1, Mod1, Gdc1 , Ce2, Es3 as genetic markers, linkage test crosses (two-point test) consisting of intercrossing uncovered BALB/c mice (homozygotes) to CBA/N and C57BL/6 mice with normal hair and backcrossing the heterozygotes of the F1 to the uncovered BALB/c mice were made. It was soon evident that the mutation was linked to Es3 on chromosome 11. Furthermore, three-point test was made by using Es3 and D11 Mit8 (a microsatellite DNA) as genetic markers. The result showed that the mutation was linked to Es3 with the percentage recombination of (7.89 ± 2.19) %, and linked to D11Mit8 with the percentage recombination of (26.30 ± 3.57)%. The percentage recombination between Es3 and D11Mit8 was | Shanru Li Dongping Wang Hong Lan Wenyan Zhang Baosheng Ge Jiqing Li Cuie Wang Yifan Lu Yanyan Shi Runfang Li | 1999 | Chinese Science Bulletin1999，44，13： | 1 |

| 9 | In situ formation of self-antistacking FeCoO_(x) on N-doped graphene:A 3D-on-2D nanoarchitecture for long-life Zn-air batteries显示文摘Before the practical application of rechargeable Zn-air batteries(ZABs),a critical issue regarding the inherent slow reaction kinetics of the oxygen reduction(ORR)and oxygen evolution(OER)must be addressed.Here,we fabricate a cost-effective bifunctional oxygen electrocatalyst with a self-antistacking structure,where three-dimensional(3D)Fe-Co bimetallic oxide particles(FeCoO_(x))are directly grown on 2D N-doped graphene(NG).The in situ grown FeCoO_(x)particles can alleviate the NG interlaminar restacking,ensuring abundant channels for diffusion of O_(2)/OH−species,while the NG allows rapid electron flow.Benefiting from this self-antistacking 3D-on-2D structure and synergetic electrocatalysis,FeCoO_(x)@NG demonstrated excellent activity for both ORR and OER(ΔE=0.78 V),which is superior to that of the binary mixtures of Pt/C and RuO_(2)(ΔE=0.83 V).A homemade ZAB with 20%-FeCoO_(x)@NG delivers a specific capacity of 758.9 mAh g^(−1),a peak power density of 215 mW cm^(−2),and long-term cyclability for over 400 h.These research results suggest that designing a bimetallic oxide/N-doped carbon 3D-on-2D nanoarchitecture using an in situ growth strategy is an attractive and feasible solution to overcome electrocatalytic problems in ZABs. | Zehao Zheng Cuie Wang Peng Mao Yijun Zhu Ran Ran Wei Zhou Kaiming Liao Zongping Shao | 2023 | Carbon Energy2023，5，3： | 1 |

| 11 | Enhanced electrochemical performance of Li-ion batteries with nanoporous titania as negative electrodes显示文摘Nanoporous anatase TiO2(np-TiO2) electrodes have been developed via the anodization of titanium foils in fluoride containing electrolytes,and its application in rechargeable lithium-ion batteries(LIBs) was investigated. Four different types of np-TiO2 electrodes with different pore diameters of 14.7±8.2 nm, 12.8±6.8 nm, 11.0±5.5, and 26.7±13.6 nm were fabricated for evaluating the effect of nanoporous characteristics on the LIB performance. The discharge capacity of the four battery types 1, 2, 3, and 4 were 132.7 m Ah g-1, 316.7 m Ah g-1, 154.3 m Ah g-1,and 228.4 m Ah g-1, respectively. In addition, these electrodes 1, 2, 3, and 4 exhibited reversible capacity of 106.9 m Ah g-1after 295 th,180.9 m Ahg-1 after 220 th, 126.1 m Ah g-1after 150 th, and 206.7 m Ahg-1after 85 th cycle at a rate of 1 C, respectively. It was noted that the cyclic life of the batteries had an inverse relationship, and the capacity had a proportional relationship to the pore diameter. The enhanced electrochemical performance of the nanoporous electrodes can be attributed to the improved conductivity and the enhanced kinetics of lithium insertion/extraction at electrode/electrolyte interfaces because of the large specific surface area of np-TiO2 electrodes. | Md.Arafat Rahman Xiaojian Wang Cuie Wen | 2015 | Journal of Energy Chemistry2015，24，2： | 0 |
| 12 | Enhanced stability and electrochemical properties of lanthanum and cerium co-modified LiVOPO_(4) cathode materials for Li-ion batteries显示文摘A facile and efficient ball-milling assisted sol-gel synthesis route was developed to prepare triclinic e-LiVOPO_(4)(LVOP)material with lanthanum(La)and cerium(Ce)modification individually as well as simultaneously.An LVOP/LaPO_(4)/CePO_(4)composite cathode material was successfully synthesized and results show that La and Ce co-modification noticeably improves the electrochemical performance by enhancing the high voltage capacity upon cycling,which indicates contributions from the good ionic conductors LaPO_(4)and CePO_(4).The simultaneous La and Ce modification improves the high voltage performance significantly with an increase of 50%in high voltage capacity after 20 cycles compared to pure LVOP.It also shows stabilized cycling perfo rmance with 91%capacity rete ntion after 50 cycles at 0.1 C rate,along with high-rate capability with a capacity of 83.1 mAh/g compared to the pristine sample showing the capacity of 51.6 mAh/g at a high rate of 5C.This can be attributed to the good conductivity of LaPO_(4)and CePO_(4).In addition,the LVOP/LaPO_(4)/CePO_(4)composite and the pristine LVOP give a charge transfer resistance of-105 and-212Ω,respectively,showing much lower impedance due to a combination of La and Ce addition. | Zishan Ahsan Zhenfei Cai Shuai Wang Haichuan Wang Yangzhou Ma Guangsheng Song Shihong Zhang Weidong Yang Muhammad Imran Cuie Wen | 2023 | Journal of Rare Earths2023，41，10： | 0 |
| 13 | Binary Zn–Ti alloys for orthopedic applications:Corrosion and degradation behaviors,friction and wear performance,and cytotoxicity显示文摘Zinc(Zn)and its biocompatible and biodegradable alloys have substantial potential for use in orthopedic implants.Nevertheless,pure Zn with a hexagonal close-packed crystal structure has only two independent slip systems,therefore exhibiting extremely low elongation and yield strength in its ascast condition,which restricts its clinical applications.In this study,as-cast Zn–xTi(titanium)(x=0.05,0.10,0.20,and 0.30 wt.%)binary alloys were hot-rolled and their microstructures,mechanical properties,wear resistance,and cytocompatibility were comprehensively investigated for orthopedic implant applications.The microstructures of both as-cast and hot-rolled Zn–xTi alloys consisted of anα-Zn matrix phase and a TiZn16 phase,while Zn–0.2 Ti and Zn–0.3 Ti exhibited a finerα-Zn phase due to the grainrefining effect of Ti.The hot-rolled Zn–0.2 Ti alloy exhibited the highest yield strength(144.5 MPa),ultimate strength(218.7 MPa),and elongation(54.2%)among all the Zn–x Ti alloys.The corrosion resistance of Zn–xTi alloys in Hanks’solution decreased with increasing addition of Ti,and the hot-rolled Zn–0.3 Ti alloy exhibited the highest corrosion rates of 432μm/y as measured by electrochemical testing and 57.9μm/y as measured by immersion testing.The as-cast Zn–xTi alloys showed lower wear losses than their hot-rolled counterparts.The extracts of hot-rolled Zn–x Ti alloys at concentrations of≤25%showed no cytotoxicity to MG-63 osteosarcoma cells and the extracts of Zn–xTi alloys exhibited enhanced cytocompatibility with increasing Ti content. | Kun Wang Xian Tong Jixing Lin Aiping Wei Yuncang Li Matthew Dargusch Cuie Wen | 2021 | Journal of Materials Science & Technology2021，，15： | 0 |
| 14 | Fatigue and corrosion fatigue behaviors of biodegradable Zn-Li and Zn-Cu-Li under physiological conditions显示文摘Zinc(Zn)alloys are emerging as a new class of biodegradable metallic materials due to their good biocompatibility,suitable biodegradability,and nontoxicity.However,the dynamic loading in the human body,along with the corrosive physiological environment,brings great challenges to the application of biodegradable Zn alloys.At present,there are few reports on the fatigue and corrosion fatigue properties of Zn alloys in simulated body fluid(SBF).In the present work,extruded Zn-0.8Li and Zn-2Cu-0.8Li alloys were selected in order to systematically evaluate their fatigue and corrosion fatigue behaviors both in air at ambient temperature and in SBF at 37℃.Results revealed that the fatigue limits of the extruded Zn-0.8Li and Zn-2Cu-0.8Li alloys were about 135 and 180 MPa,respectively,in air at ambient temperature.However,the fatigue limits of the two alloys decreased to 65 and 80 MPa,respectively,in SBF at 37℃and showed a linear relationship between the corrosion fatigue life and the stress amplitude.The sources of fatigue cracks in air were internal microstructural defects or weak mechanical properties of the material,while the initiation of corrosion pits on the surface was the main reason for the source of the formation of fatigue cracks in SBF.The fracture mode of the extruded Zn-0.8Li and Zn-2Cu-0.8Li alloys was quasi-cleavage fracturing.Compared to static immersion testing,cyclic loading significantly increased the corrosion rates of the two experimental alloys in a corrosion fatigue environment. | Huafang Li Yan Huang Xiaojing Ji Cuie Wen Lu-Ning Wang | 2022 | Journal of Materials Science & Technology2022，，36： | 0 |
