| 1 | In vivo biocompatibility and degradability of a Zn-Mg-Fe alloy osteosynthesis system显示文摘Zinc is generally considered to be one of the most promising materials to be used in biodegradable implants,and many zinc alloys have been optimized to improve implant biocompatibility,degradation,and mechanical properties.However,long-term degradation leads to the prolonged presence of degradation products,which risks foreign body reactions.Herein,we investigated the in vivo biocompatibility and degradation of a biodegradable Zn-Mg-Fe alloy osteosynthesis system in the frontal bone,mandible,and femur in beagles for 1 year.Results of the routine blood,biochemical,trace element,and histological analyses of multiple organs,peripheral blood CD4/CD8a levels,and serum interleukin 2 and 4 levels showed good biocompatibility of the Zn-Mg-Fe alloy.Zinc content analysis revealed zinc accumulation in adjacent bone tissue,but not in the liver,kidney,and spleen,which was related to the degradation of the Zn-Mg-Fe alloy.The alloy demonstrated a uniform slowing degradation rate in vivo.No degradation differences in the frontal bone,mandible,and femur were observed.The degradation products included zinc oxide[ZnO],zinc hydroxide[Zn(OH)_(2)],hydrozincite[Zn_(5)(OH)_(6)(CO_(3))_(2)],and hopeite[Zn_(3)(PO_(4))_(2)⋅4H_(2)O].The good biocompatibility and degradation properties of the Zn-Mg-Fe alloy render it a very attractive osteosynthesis system for clinical applications. | Xiaoxi Shao Xiang Wang Fangfang Xu Taiqiang Dai Jack G.Zhou Jiang Liu Kun Song Lei Tian Bin Liu Yanpu Liu | 2022 | Bioactive Materials2022，7，1： | 1 |
| 2 | Designs and applications of electrohydrodynamic 3D printing显示文摘This paper mainly reviews the designs of electrohydrodynamic(EHD)inkjet printing machine and related applications.The review introduces the features of EHD printing and its possible research directions.Significant progress has been identified in research and development of EHD high-resolution printing as a direct additive manufacturing method,and more effort will be driven to this direction soon.An introduction is given about current trend of additive manufacturing and advantages of EHD inkjet printing.Designs of EHD printing platform and applications of different technologies are discussed.Currently,EHD jet printing is in its infancy stage with several inherent problems to be overcome,such as low yielding rate and limitation of stand-off height.Some potential modifications are proposed to improve printing performance.EHD highresolution printing has already been applied to precision components for electronics and biotechnology applications.This paper gives a review about the latest research regarding EHD used for high-resolution inkjet printing.A starting base is given to help researchers and students to get a quick overview on the recent development of EHD printing technology. | Dajing Gao Jack G.Zhou | 2019 | International Journal of Bioprinting2019，5，1： | 1 |

| 7 | Mechanical behavior of advanced nano-laminates embedded with carbon nanotubes-a review显示文摘Embedding carbon nanotubes(CNTs)in load-bearing composite laminate hosts to turn them into nano-laminates is a rapidly emerging field and has tremendous potential in enhancing the mechanical performance of the host laminates.This state-of-the-art review intends to provide a physical insight into the understanding of the enhancing mechanisms of the processed and controlled CNTs in the nano-laminates.It focuses on four aspects:(1)physical characteristics of CNTs,including CNT length,diameter,weight percentage and surface functionalization;(2)processing and control techniques of CNTs in the fabrication of nano-laminates,including distribution,dispersion and orientation controls of CNTs;(3)mechanical properties along with their testing methods,including tension,in-plane compression,in-plane and interlaminar shear(ILS),flexure,mode I and mode II fracture toughness as well as compression-after-impact(CAI),ballistic protection and fatigue;and(4)CNT-matrix load transfer and enhancing mechanisms along with a few major governing factors.The selective and uniform production of CNTs with specific dimensions and physical properties has yet to be achieved on a consistent basis.Moreover,the processing details of CNTs vary very significantly among different researchers so that the processed CNTs share little common characteristics.There is little control over the CNT orientations in most fabrication processes of the nano-laminates except for some cases associated with chemical vapor deposition(CVD).There are only two reports on in-plane compression and there is only one on in-plane shear.For reinforcement-dominated mechanical properties such as longitudinal tension and flexure,there was little enhancement reported.However,the substantial enhancement in in-plane compression strength was also reported.For matrix-dominated mechanical properties,such as transverse tension,in-plane shear,ILS strength and mode I and mode II fracture toughness,a significant enhancement,albeit with substantially varying degrees,was reported for ILS strength and mode I and mode II fracture toughness values.Meanwhile,the lack of consistent characterization of those properties was also noticeable.There is little established understanding of the enhancing mechanisms in nanolaminates. | G.Zhou G.Xie X.Bao | 2010 | International Journal of Smart and Nano Materials2010，1，2： | 0 |
| 8 | High-pressure/low-temperature Metamorphism in Northern Hubei Province,Central China显示文摘The Qinling-Dabie accretionary fold belt in east-central China represents the E-W trending suture zone between the Sino-Korean and Yangtze cratons. A portion of the accretionary complex exposed in northern Hubei Province contains a high-pressure / low-temperature metamorphic sequence progressively metamorphosed from the blueschist through greenschist to epidote-amphibolite / eclogite facies. The Hongan metamorphic belt can be divided into three metamorphic zones,based on progressive changes in mineral assemblages: Zone Ⅰ,in the south,is characterized by transitional blueschist-greenschist facies; ZoneⅡis characterized by greenschist facies; ZoneⅢ,in the northern most portion of the belt,is characterized by eclogite and epidote-amphibolite facies sequences. Changes in amphibole compositions from south to north as well as the appearance of increasingly higher pressure mineral assemblages toward the north document differences in metamorphic P-T conditions during formation of this belt. Preliminary P-T estimates for Zone I metamorphism are 5 ~ 7 kbar,350 ~ 450℃; estimates for Zone III eclogites are 10 ~ 22 kbar,500 ±50℃. The petrographic,chemical and structural characteristics of this metamorphic belt indicate its evolutionin a northward-dipping subduction zone and subsequent uplift prior to and during the final collisionbetween the Sino-Korean and Yangtze cratons. | G.Zhou Y.J.Liu E.A.Eide J.G.Liou W.G.Ernst | 2016 | 资源环境与工程2016，30，B04： | 0 |
