| 1 | Study on β-TCP Coated Porous Mg as a Bone Tissue Engineering Scaffold Material显示文摘Three-dimensional honeycomb-structured magnesium (Mg) scaffolds with interconnected pores of accurately controlled pore size and porosity were fabricated by laser perforation technique. Biodegradable and bioactive β-tricalcium phosphate (β-TCP) coatings were prepared on the porous Mg to further improve its biocompatibility, and the biodegradation mechanism was simply evaluated in vitro. It was found that the mechanical properties of this type of porous Mg significantly depended on its porosity. Elastic modulus and compressive strength similar to human bones could be obtained for the porous Mg with porosity of 42.6%-51%. It was observed that the human osteosarcoma cells (UMR106) were well adhered and proliferated on the surface of the β-TCP coated porous Mg, which indicates that the β-TCP coated porous Mg is promising to be a bone tissue engineering scaffold material. | Fang Geng Lili Tan Bingchun Zhang Chunfu Wu Yonglian He Jingyu Yang Ke Yang | 2009 | Journal of Materials Science & Technology2009，25，1： | 13 |
| 2 | Fluoride Conversion Coating on Biodegradable AZ31B Magnesium Alloy显示文摘A fluoride conversion coating was successfully prepared on AZ31 B magnesium alloy by chemical reaction in hydrofluoric acid.Morphologies,composition,bonding strength,corrosion properties,in vitro cytotoxicity and antibacterial properties of the coating were investigated,respectively.The scanning electron microscopy observations revealed a dense coating with some irregular pores.The thin-film X-ray diffraction analysis indicated that the coating was mainly composed of MgO and MgF2.The electrochemical impedance spectroscopy results showed that the fluoride conversion coating significantly improved the corrosion resistance of AZ31 B.The hydroxyapatite formed on the surface of the fluoride coated AZ31 B after being immersed in the simulated blood plasma indicated the good bioactivity of the material.The in vitro cytotoxicity test showed that the fluoride coated AZ31 B alloy was not toxic to BMMSCs(human bone marrow-derived mesenchymal stem cells).It was also found that the fluoride coated AZ31 B alloy had antibacterial capability. | Tingting Yan Lili Tan Bingchun Zhang Ke Yang | 2014 | Journal of Materials Science & Technology2014，30，7： | 11 |
| 3 | Nickel-free Stainless Steel for Medical Applications显示文摘BIOSS4 steel is essentially a nickel-free austenitic stainless steel developed by the Institute of Metal Research, Chinese Academy of Sciences, in response to nickel allergy problems associated with nickel-containing stainless steels that are widely used in medical applications. The high nitrogen content of this steel effectively maintains the austenitic stability and also contributes to the high levels of corrosion resistance and strength. BIOSS4 steel possesses a good combination of high strength and toughness, better corrosion resistance, and better blood compatibility, in comparison with the medical 316L stainless steel. Potential applications of BIOSS4 steel can include medical implantation material and orthodontic or orthopedic devices, as well as jewelries and other decorations. | Yibin REN, Ke YANG, Bingchun ZHANG, Yaqing WANG and Yong LIANGInstitute of Metal Research, Chinese Academy of Sciences, Shenyang 110016, China | 2004 | Journal of Materials Science & Technology2004，20，5： | 11 |
| 4 | Hydroisomerization performance of platinum supported on ZSM-22/ZSM-23 intergrowth zeolite catalyst显示文摘Hydroisomerization catalysts Pt/ZSM-22,Pt/ZSM-23,and Pt/ZSM-22/ZSM-23 were prepared by supporting Pt on ZSM-22,ZSM-23,and intergrowth zeolite ZSM-22/ZSM-23,respectively.The typical physicochemical properties of these catalysts were characterized by X-Ray Diffraction(XRD),N2 absorption-desorption,Pyridine-Fourier Transform Infrared(Py-FTIR),Transmission Electron Microscopy(TEM),X-Ray Fluorescence(XRF),Scanning Electron Microscopy(SEM) and NH3-Temperature Programmed Desorption(NH3-TPD),and the performance of these catalysts in n-dodecane hydroisomerization was evaluated in a continuous down-flow fixed bed with a stainless steel tubular reactor.The characterization results indicated that the intergrowth zeolite ZSM-22/ZSM-23 possessed the dual structure of ZSM-22 and ZSM-23,and the catalyst Pt/ZSM-22/ZSM-23 had similar pores and weak acidity to Pt/ZSM-22 and Pt/ZSM-23 catalysts.Moreover,Pt/ZSM-22/ZSM-23 catalyst showed a high selectivity in hydroisomerization of long chain n-alkanes to mono-branched isomers.The evaluation results for n-dodecane hydroisomerization indicated that the activity of Pt/ZSM-22/ZSM-23 was the lowest,while the hydroisomerization selectivity was the highest among the three catalysts.The maximum yield of i-dodecane product was 68.3% over Pt/ZSM-22/ZSM-23 at 320 oC. | Chi Kebin Zhao Zhen Tian Zhijian Hu Sheng Yan Lijun Li Tianshu Wang Bingchun Meng Xiangbin Gao Shanbin Tan Mingwei Liu Yanfeng | 2013 | Petroleum Science2013，10，2： | 8 |

| 6 | In vitro Study on a New High Nitrogen Nickel-free Austenitic Stainless Steel for Coronary Stents显示文摘Most commercialized coronary stents are made of 316L stainless steels due to its good combination of properties,and currently some new stents are made of cobalt-based alloy owing to its higher mechanical properties. However,the presence of high quantity of nickel and/or cobalt elements in these materials,which are known to trigger the toxic and allergic responses,has caused many concerns.Nickel-free austenitic stainless steels have been developed in order to solve these problems.In this paper,based on the development of a new Fe-Cr-Mn-Mo-N type high nitrogen nickel-free austenitic stainless steel,properties such as mechanical property,corrosion resistance in Hank s solution,and in vitro blood compatibility including the kinetic clotting time and the platelets adhesion,were investigated in comparison to the above two conventional materials,a 316L stainless steel and a Co-28Cr-6Mo alloy.The results showed that the new high nitrogen steel possessed better combination of mechanical properties,corrosion resistance and blood compatibility than those of 316L steel and the Co-28Cr-6Mo alloy,and can be a promising alternative material for manufacture of coronary stents. | Yibin Ren Peng Wan Feng Liu Bingchun Zhang Ke Yang | 2011 | Journal of Materials Science & Technology2011，27，4： | 6 |
| 7 | In vitro study on infectious ureteral encrustation resistance of Cu-bearing stainless steel显示文摘Cu-bearing stainless steel has been found to have obvious inhibition performance against encrustation in vitro. This study was aiming to further investigate the inhibitory effect of a Cu-bearing stainless steel(316 L-Cu SS) on the infectious encrustation based on its antimicrobial activity. The encrustation in presence of bacteria, antibacterial performance, urease production and Ca and Mg precipitation were examined by scanning electron microscopy, antibacterial assay, enzyme-linked immunosorbent assay and inductively coupled plasma-mass spectrometry, respectively. It was found that 316 L-Cu SS could inhibit the formation of bacterial biofilm due to the release of Cu^(2+) ions and then decrease the urease amount splitting by bacteria, which produced a neutral environment with pH around 7. However, more encrustations coupled with bacterial biofilms on the surface of comparison stainless steel(316 L SS) with an alkaline environment were recorded. It can thus be seen that the 316 L-Cu SS highlights prominent superiority against encrustation in the presence of microorganisms. | Jing Zhao Ling Ren Bingchun Zhang Zhiqiang Cao Ke Yang | 2017 | Journal of Materials Science & Technology2017，33，12： | 6 |
| 8 | 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 |
| 9 | High nitrogen stainless steel drug-eluting stent-Assessment of pharmacokinetics and preclinical safety in vivo显示文摘Pharmacokinetic analyses were performed using 20 pigs for 120-days implantation,while one sirolimus-eluting stent was implanted into one of their coronary artery.At different time points,the residual sirolimus on the stent,delivered locally(to artery wall),regionally(to adjacent and downstream muscle)and systemically(to plasma and visceral organs),was detected throughout 120 days.Preclinical safety evaluation was performed using 32 pigs for 180-days implantation to study the safety of metal platform material and the effectiveness of sirolimus eluting coating on the HNS stent.The neointima area,restenosis rate and inflammatory grade for HNS and control group stents were detected and analyzed.Approximately 80%sirolimus was eluted from the sirolimuseluting stents after 30-days implantation in vivo.Additionally,there was sustained sirolimus in the artery wall,cardiac muscle and heart throughout 120-days implantation,and sirolimus accumulated to the peak at 90-days implantation.It was inferred that the sirolimus eluting stent in this study was covered by neointima before 90-days implantation,indicating that the sirolimus eluting coating on the HNS stent was safe and effective.Very little sirolimus was distributed in visceral organs after 14-days implantation.HNS sirolimus-eluting stent exhibited lower restenosis rate and lower inflammatory grade than control group,which verified that the sirolimus-eluting coating design in this study was reasonable and practical.In addition,there were no significant difference in restenosis rate and inflammatory score between HNS bare-metal stent and drug-eluting stents,illustrating that HNS has good bio-compatibility and is suitable to use as coronary artery stent material. | Shanshan Chen Zhifeng Yao Yongbiao Guan Hui Yang M.Babar Shahzad Yizhe Wu Bingchun Zhang Li Shen Ke Yang | 2020 | Bioactive Materials2020，5，4： | 3 |
| 10 | Laser Remelting of Plasma Sprayed NiCrAlY and NiCrAlY-Al_2O_3 Coatings显示文摘Two types of plasma sprayed coatings (NiCrAlY and NiCrAlY-A12O3) were remelted by a 5 kW cw CO2 laser. With increasing laser power and decreasing traverse speed in the ranges of 200-700 W and 5-30 mm/s respectively, the melted track grew in width and depth. In the optimum range of laser parameters, a homogeneous remelted layer without voids, cavities, unmelted particles and microcracks was formed. On the surface of remelted layers, Al203 and YAIO3 were detected. As a result of isothermal oxidation tests, weight gains of laser remelted coatings were obviously lower than that only plasma sprayed, especially laser remelted NiCrAlY-Al2O3 coatings. The effects of laser remelting and incorporation of A12O3 second phase in N1CrAlY matrix on high temperature oxidation resistance were discussed. | Yingna WU, Gang ZHA NC, Bingchun ZHANG, Zhongchao FENG and Yong LIANG Institute of Metal Research, Chinese Academy of Sciences, Shenyang 110016, China Fangjun LIU Key Laboratory for High Energy Density Beam Processing Technology, Beijing Aeronautical Manu | 2001 | Journal of Materials Science & Technology2001，17，5： | 3 |
| 11 | Fabrication and Characterization of Ca-Mg-P Containing Coating on Pure Magnesium显示文摘A biodegradable Ca-P coating mainly consisting of β-tricalcium phosphate(β-TCP) was fabricated on pure magnesium via the chemical deposition in a simulated Hank s solution.The method significantly accelerated the coating formation on magnesium.Moreover,the morphology,phase/chemical composition,the coating formation mechanism as well as degradation behavior in phosphate buffered saline(PBS) solution were investigated.Scanning electron microscopy(SEM) images showed that the coating had three layers and X-ray diffraction(XRD) patterns showed that the coating mainly contained Ca3(PO4)2 and(Ca,Mg)3(PO4)2.Electrochemical test showed that the corrosion current density(Icorr) of the coated Mg was decreased by about one order of magnitude as compared to that of pure magnesium.The immersion test indicated that the coating could obviously reduce the degradation rate. | Yanjin Lu Lili Tan Honglia. ng Xiang Bingchun Zhang Ke Yang Yangde Li | 2012 | Journal of Materials Science & Technology2012，28，7： | 3 |
| 12 | Analysis of Magnetism in High Nitrogen Austenitic Stainless Steel and Its Elimination by High Temperature Gas Nitriding显示文摘Stable austenitic structure in medical stainless steels is basically required for surgical implantation. A weak magnetism was found in a high nitrogen nickel-free austenitic stainless steel for cardiovascular stent application. This magnetic behavior in high nitrogen stainless steel was investigated by optical microscopy, X-ray diffraction (XRD), electron probe microanalysis (EPMA) and superconducting quantum interference device (SQUID). The results showed that the magnetism came from the composition segregation of ferrite formation elements such as Cr and Mo in the steel and some δ-ferrites were locally formed during the pressurized electroslag remelting process. The magnetism of high nitrogen stainless steel could be eliminated by a proper high temperature gas nitriding (HTGN). | Peng Wan Yibin Ren Bingchun Zheng Ke Yang | 2011 | Journal of Materials Science & Technology2011，27，12： | 3 |
| 13 | SStudy on corrosion resistance of pure magnesium with CaSiO_3 contained coating in NaCl solution显示文摘A composite coating was fabricated on pure magnesium by hydrothermal treatment in order to reduce its degradation in body environment.The coating was characterized by scanning electron microscopy(SEM) and X-ray diffraction(XRD).The XRD pattern showed that the main composition of the coating was a mixture of CaSiO3,MgSiO3 and Mg(OH)2.Electrochemical test showed that the corrosion current density(icorr) of the coated magnesium was decreased by about two orders of magnitude compared with that of the bare magnesium,and the EIS measurement also showed that the corrosion resistant performance of the coated magnesium was significantly enhanced.Meanwhile,weight loss test showed that the weight loss of the coated magnesium was lower than that of the bare magnesium.Hence,the present study indicated that the composite coating could greatly slow down the degradation of pure magnesium. | Yanjin LU Lili TAN Hongliang XIANG Bingchun ZHANG Ke YANG | 2012 | Acta Metallurgica Sinica(English Letters)2012，25，4： | 2 |
| 14 | In Vivo Study on Degradation Behavior and Histologic Response of Pure Magnesium in Muscles显示文摘When an orthopedics device is implanted into bone injury site, it will contact the soft tissue(skeletal muscle, fascia, ligament etc.) except for bone. Magnesium based biodegradable metals are becoming an important research object in orthopedics due to their bioactivity to promote bone healing. In this study,pure Mg rods with and without chemical conversion coating were implanted into the muscle tissue of rabbits. Implants and their surrounding tissues were taken out for weight loss measurement, crosssectional scanning electron microscopy observation, elemental distribution analysis and histological examination. The results showed that the chemical conversion coating would increase the in vivo corrosion resistance of pure Mg and decrease the accumulation of calcium(Ca) and phosphorus(P) elements around the implants. For the bare magnesium implant, both Ca and P contents in the surrounding tissues increased at the initial stage of implantation and then decreased at 12 weeks implantation, while for the magnesium with chemical conversion coating, Ca and P contents in the surrounding tissues decreased with the implantation time, but were not significant. The histological results demonstrated that there was no calcification in the muscle tissue with implantation of magnesium for up to 12 weeks. The chemical conversion coating not only increased the in vivo corrosion resistance of pure Mg, but also avoided the depositions of Ca and P in the surrounding tissues, meaning that pure magnesium should be biosafe when contacting with muscle tissues. | Shanshan Chen Lili Tan Bingchun Zhang Yonghui Xia Ke Xu Ke Yang | 2017 | Journal of Materials Science & Technology2017，33，5： | 2 |
