| 1 | Gaseous sulfur trioxide induced controllable sulfonation promoting biomineralization and osseointegration of polyetheretherketone implants显示文摘Fabricating a desired porous structure on the surface of biomedical polyetheretherketone(PEEK)implants for enhancing biological functions is crucial and difficult due to its inherent chemical inertness.In this study,a porous surface of PEEK implants was fabricated by controllable sulfonation using gaseous sulfur trioxide(SO3)for different time(5,15,30,60 and 90 min).Micro-topological structure was generated on the surface of sulfonated PEEK implants preserving original mechanical properties.The protein absorption capacity and apatite forming ability was thus improved by the morphological and elemental change with higher degree of sulfonation.In combination of the appropriate micromorphology and bioactive sulfonate components,the cell adhesion,migration,proliferation and extracellular matrix secretion were obviously enhanced by the SPEEK-15 samples which were sulfonated for 15 min.Finding from this study revealed that controllable sulfonation by gaseous SO3 would be an extraordinarily strategy for improving osseointegration of PEEK implants by adjusting the microstructure and chemical composition while maintaining excellent mechanical properties. | Teng Wan Zixue Jiao Min Guo Zongliang Wang Yizao Wan Kaili Lin Qinyi Liu Peibiao Zhang | 2020 | Bioactive Materials2020，5，4： | 5 |
| 2 | In situ synthesis and phase analysis of low density O'-sialon-based multiphase ceramics显示文摘In situ formed low density O'-sialon-based multiphase ceramics were prepared by liquid-phase sintering method at 1400°C with Si3N4, SiO2 and Al2O3 as raw materials.Crystalline phases were identified by X-ray diffraction(XRD).The quantitative phase analysis was finished by matrix-flushing method and the substitution parameter x value of O'-sialon was estimated.The effects of sintering additives on the phase composition of the material were studied.The results show that, when using Y2O3 alone, Al6Si2O13 phase can be formed in the material, but when using Y2O3 and MgO, MgAl2O4 phase can be preferentially formed and the Al6Si2O13 is not observed.The mechanical properties of the material were measured and the relationships between microstructure and mechanical properties were discussed.The sample with Y2O3 and MgO sintering additives, using fused quartz alone as SiO2 source, displays a combination of high bending strength(163 MPa) and good fracture toughness(3.11 MPa·m1/2).Bending strength and fracture toughness of the samples increase with the increase of the content and aspect ratio of elongated grains and decrease with the increase of the porosity. | XU Xiongwen, LIANG Hui, LI Xiaolei, JI Huiming, LU Huixiang, and WAN Yizao Key Laboratory for Advanced Ceramics and Machining Technology(Ministry of Education), Tianjin University, Tianjin 300072, China | 2010 | Rare Metals2010，29，2： | 3 |
| 3 | Optimization of annealing treatment and comprehensive properties of Cu-containing Ti6Al4V-xCu alloys显示文摘The Ti6Al4V-Cu alloy was reported to show good antibacterial properties, which was promising to reduce the hazard of the bacterial infection problem. For the purpose of preparing Ti6Al4V-Cu alloy with satisfied comprehensive properties, it’s important to study the heat treatment and the appropriate Cu content of the alloy. In this study, high Cu content Ti6Al4V-x Cu(x = 4.5, 6, 7.5 wt%) alloys were prepared, and firstly the annealing heat treatments were optimized in the α+β+Ti2Cu triple phase region to obtain satisfied tensile mechanical properties. Then the effect of Cu content on the tribological property, corrosion resistance, antibacterial activity and cytotoxicity of the Ti6Al4 V-x Cu alloys were systematically studied to obtain the appropriate Cu content. The results showed that the optimal annealing temperatures for Ti6Al4 V-x Cu(x = 4.5, 6, 7.5 wt%) alloys were 720, 740 and 760℃, respectively, which was resulted from the proper volume fractions of α,β and Ti2Cu phases in the microstructure. The additions of 4.5 wt% and 6 wt% Cu into the medical Ti6Al4 V alloy could enhance the wear resistance and corrosion resistance of the alloy, but the addition of 7.5 wt% Cu showed an opposite effect. With the increase of the Cu content, the antibacterial property was enhanced due to the increased volume fraction of Ti2Cu phase in the microstructure, but when the Cu content was increased to 7.5 wt%, cytotoxicity was presented. A medium Cu content of 6 wt%, with annealing temperature of 740℃ make the alloy possesses the best comprehensive properties of tensile properties, wear resistance, corrosion resistance, antibacterial property and biocompatibility, which is promising for future medical applications. | Cong Peng Yang Liu Hui Liu Shuyuan Zhang Chunguang Bai Yizao Wan Ling Ren Ke Yang | 2019 | Journal of Materials Science & Technology2019，35，10： | 3 |
| 4 | Layer-by-Layer Assembled Bacterial Cellulose/Graphene Oxide Hydrogels with Extremely Enhanced Mechanical Properties显示文摘Uniform dispersion of two-dimensional(2 D) graphene materials in polymer matrices remains challenging. In this work, a novel layer-by-layer assembly strategy was developed to prepare a sophisticated nanostructure with highly dispersed 2 D graphene oxide in a three-dimensional matrix consisting of onedimensional bacterial cellulose(BC) nanofibers. This method is a breakthrough, with respect to the conventional static culture method for BC that involves multiple in situ layer-by-layer assembly steps at the interface between previously grown BC and the culture medium. In the as-prepared BC/GO nanocomposites, the GO nanosheets are mechanically bundled and chemically bonded with BC nanofibers via hydrogen bonding,forming an intriguing nanostructure. The sophisticated nanostructure of the BC/GO leads to greatly enhanced mechanical properties compared to those of bare BC. This strategy is versatile, facile, scalable, and can be promising for the development of high-performance BC-based nanocomposite hydrogels. | Honglin Luo Jiaojiao Dong Fanglian Yao Zhiwei Yang Wei Li Jie Wang Xinhua Xu Jian Hu Yizao Wan | 2018 | Nano-Micro Letters2018，10，3： | 2 |
| 5 | An in vivo study on the effect of coating stability on osteointegration performance of collagen/hyaluronic acid multilayer modified titanium implants显示文摘Aseptic loosening of implant is one of the main causes of Ti-based implant failure.In our previous work,a novel stable collagen/hyaluronic acid(Col/HA)multilayer modified titanium coatings(TCs)was developed by layer-by-layer(LBL)covalent immobilization technique,which showed enhanced biological properties compared with TCs that were physically absorbed with Col/HA multilayer in vitro.In this study,a rabbit model with femur condyle defect was employed to compare the osteointegration performance of them.Results indicated that Col/HA multilayer with favourable stability could better facilitate osteogenesis around implants and bone-implant contact.The Col/HA multilayer covalentimmobilized TC may reduce aseptic loosening of implant. | Haiyong Ao Jiajia Zong Yanjiao Nie Yizao Wan Xiebin Zheng | 2018 | Bioactive Materials2018，3，1： | 2 |
| 6 | Synthesis of ZnO by Chemical Bath Deposition in the Presence of Bacterial Cellulose显示文摘The control of the morphology of zinc oxide(ZnO) crystals is very important in science and industry.This article reports the influence of bacterial cellulose(BC) on the morphology of ZnO prepared by chemical bath deposition.ZnO nanostructures synthesized with and without adding BC to the aqueous solution of zinc acetate and ammonia were characterized by scanning electron microscopy,transmission electron microscopy,and X-ray diffraction.The results reveal that the presence of BC in the aqueous solution changes the morphology from spindle to flower,which is ascribed to the interactions between –OH on BC nanofibers and Zn2?in the solution.In addition,optical property of the two ZnO nanostructures was compared. | Guangyao Xiong Honglin Luo Jing Zhang Jun Jin Yizao Wan | 2014 | Acta Metallurgica Sinica(English Letters)2014，27，4： | 2 |

| 8 | De novo strategy with engineering a multifunctional bacterial cellulose-based dressing for rapid healing of infected wounds显示文摘The treatment and healing of infected skin lesions is one of the major challenges in surgery.To solve this problem,collagen I(Col-I)and the antibacterial agent hydroxypropyltrimethyl ammonium chloride chitosan(HACC)were composited into the bacterial cellulose(BC)three-dimensional network structure by a novel membrane-liquid interface(MLI)culture,and a Col-I/HACC/BC(CHBC)multifunctional dressing was designed.The water absorption rate and water vapor transmission rate of the obtained CHBC dressing were 35.78±2.45 g/g and 3084±56 g m^(-2)⋅day^(-1),respectively.The water retention of the CHBC dressing was significantly improved compared with the BC caused by the introduced Col-I and HACC.In vitro results indicated that the combined advantages of HACC and Col-I confer on CHBC dressings not only have outstanding antibacterial properties against Staphylococcus aureus(S.aureus)compared with BC and CBC,but also exhibit better cytocompatibility than BC and HBC to promote the proliferation and spread of NIH3T3 cells and HUVECs.Most importantly,the results of in vivo animal tests demonstrated that the CHBC dressings fully promoted wound healing for 8 days and exhibited shorter healing times,especially in the case of wound infection.Excellent skin regeneration effects and higher expression levels of collagen during infection were also shown in the CHBC group.We believe that CHBC composites with favorable multifunctionality have potential applications as wound dressings to treat infected wounds. | Chen Zhou Zhifei Yang Xiaowei Xun Le Ma Zejing Chen Xiaoming Hu Xidong Wu Yizao Wan Haiyong Ao | 2022 | Bioactive Materials2022，7，7： | 1 |

| 17 | The Trade‑Offs in the Design of Reversible Zinc Anodes for Secondary Alkaline Batteries显示文摘Zinc-based batteries have long occupied the largest share of the primary battery market,but this advantage has not continued in the secondary battery market.This is mainly because the cycling performance of secondary zinc-based batteries is significantly limited by the poor reversibility of zinc electrodes,including the formation of zinc dendrites,electrode deformation,corrosion,and hydrogen evolution.To solve the above problems,researchers have developed many novel strategies,such as surface coating,use of electrode additives,use of electrolyte additives,and electrode structure design.However,the implementation of these strategies inevitably requires consideration of trade-offs because the core factors that limit the reversibility of zinc electrodes are not isolated but intertwined.Therefore,fully understanding the trade-offs in the zinc electrode design process is necessary to fundamentally improve the cycling performance of the zinc electrode and construct a practical secondary zinc-based battery.This perspective gives an introduction to various problems that limit the cycling of zinc electrodes and discusses the theoretical causes of these problems.The trade-offs in various typical strategies are systematically analyzed,and their positive and negative effects on performance are discussed.This work aims to provide insights for the development of highly reversible zinc anodes for practical secondary zinc-based batteries. | Honglin Luo Bin Liu Zhiwei Yang Yizao Wan Cheng Zhong | 2022 | Electrochemical Energy Reviews2022，5，1： | 1 |
