| 1 | Comparative study of the mechanical properties,micro-structure,and composition of the cranial and beak bones of the great spotted woodpecker and the lark bird显示文摘Woodpeckers are well able to resist head injury during repeated high speed impacts at 6-7 m s-1 with decelerations up to 1000 g.This study was designed to compare the mechanical properties,microstructures and compositions of cranial bone and beak bone of great spotted woodpecker(Dendrocopos major) and the Mongolian sky lark(Melanocorypha mongolica).Microstructures were observed using micro-computed tomography and scanning electron microscopy and their compositions were characterized by X-ray powder diffraction and Fourier-transform infrared spectroscopy.Under high stress,the cranial bone and the beak of the woodpecker exhibited distinctive mechanical features,which were associated with differences in micro-structure and composition,compared with those of the lark.Evolutionary optimization of bone micro-structure has enabled functional adaptation to the woodpecker's specific lifestyle.Its characteristic micro-structure efficiently avoids head impact injury and may provide potential clues to the prevention of brain injury using bio-inspired designs of shock-absorbing materials. | WANG LiZhen ZHANG HongQuan FAN YuBo | 2011 | Science China(Life Sciences)2011，54，11： | 9 |
| 2 | High-conductivity free-standing Li_(6)PS_(5)Cl/poly(vinylidene difluoride)composite solid electrolyte membranes for lithium-ion batteries显示文摘Bulk-type all-solid-state batteries(ASSBs)using sulfide solid electrolyte are considered as a promising alternative to commercial lithium-ion batteries owing to their high energy density and safety.However,cell energy density is often comparatively low due to use of a thick solid electrolyte separator and a lithium alloy as anode.For achieving high-performance ASSBs,creating a thin free-standing electrolyte with high-conductivity and good cycling stability against lithium anode is essential.In this work,we present Li_(6)PS_(5)Cl/poly(vinylidene difluoride)(LPSCl/PVDF)composite electrolytes prepared by a slurry method.The influence of the PVDF content on the microstructure,morphology,ionic conductivity and activation energy of the LPSCl/PVDF electrolytes is systematically investigated.Free-standing LPSCl/PVDF membranes with a thickness of 100-120 mm and a high ionic conductivity of about 1·10^(-3) S cm^(-1) at 25℃ are obtained.After adding PVDF to the LPSCl electrolyte,the cycling stability of the LPSCl electrolyte against lithium metal improves significantly.Therefore,LPSCl/PVDF composite electrolytes are promising candidates to be used in ASSBs. | Shuo Wang Xue Zhang Sijie Liu Chengzhou Xin Chuanjiao Xue Felix Richter Liangliang Li Lizhen Fan Yuanhua Lin Yang Shen Jurgen Janek Ce-Wen Nan | 2020 | Journal of Materiomics2020，6，1： | 5 |
| 3 | Diagonal-symmetrical and Midline-symmetrical Unit Cells with Same Porosity for Bone Implant: Mechanical Properties Evaluation显示文摘In this study, mechanical properties of bionic porous structures with diagonal-symmetrical and midline-symmetrical unit cells were studied when the porosities were same. Three typical unit cells (Diamond (DO), Rhombic Dodecahedron (RD), and Octet Truss (OT)) were selected, in which DO has diagonal-symmetrical shape, while RD and OT share midline-symmetrical structure. Based on the same porosity, corresponding models were designed, and Ti6Al4V samples were manufactured by electron beam melting. Then, using Mechanical Properties Testing (MPT) and Finite Element Analysis (FEA) methodologies, mechanical properties and transmissions of different porous structures were evaluated. Besides, composition and details before and after printing were analyzed with Energy Dispersive Spectrometer (EDS), X-ray diffraction (XRD) and Scanning Electron Microscope (SEM). MPT results showed that midline-symmetrical shape would have superior compressive performance than diagonal-symmetrical shape, but opposite trend for the torsion performance, which were in line with FEA prediction. Furthermore, effective modulus of DO, RD and OT were 2.59 GPa, 4.89 GPa, and 1.77 GPa, approximating the mechanical properties of human bones. Additionally, manufacturing defects and discrepancies between FEA and MPT were found. This study would provide great helps for unit cell selection and initial mechanical properties matching for optimum bone implants. | Jian Li Diansheng Chen Yingying Zhang Yan Yao Zhongjun Mo Lizhen Wang Yubo Fan | 2019 | Journal of Bionic Engineering2019，16，3： | 4 |

| 5 | The effect of mechanical loads on the degradation of aliphatic biodegradable polyesters显示文摘Aliphatic biodegradable polyesters have been the most widely used synthetic polymers for developing biodegradable devices as alternatives for the currently used permanent medical devices.The performances during biodegradation process play crucial roles for final realization of their functions.Because physiological and biochemical environment in vivo significantly affects biodegradation process,large numbers of studies on effects of mechanical loads on the degradation of aliphatic biodegradable polyesters have been launched during last decades.In this review article,we discussed the mechanism of biodegradation and several different mechanical loads that have been reported to affect the biodegradation process.Other physiological and biochemical factors related to mechanical loads were also discussed.The mechanical load could change the conformational strain energy and morphology to weaken the stability of the polymer.Besides,the load and pattern could accelerate the loss of intrinsic mechanical properties of polymers.This indicated that investigations into effects of mechanical loads on the degradation should be indispensable.More combination condition of mechanical loads and multiple factors should be considered in order to keep the degradation rate controllable and evaluate the degradation process in vivo accurately.Only then can the degradable devise achieve the desired effects and further expand the special applications of aliphatic biodegradable polyesters. | Ying Li Zhaowei Chu Xiaoming Li Xili Ding Meng Guo Haoran Zhao Jie Yao Lizhen Wang Qiang Cai Yubo Fan | 2017 | Regenerative Biomaterials2017，4，3： | 2 |

| 8 | Biomechanism of resistance to retinal injury in woodpecker’s eyes显示文摘Retinal injury is the most common ocular impairment associated with shaken baby syndrome(SBS), which could lead to vision loss and blindness. However, a woodpecker does not develop retinal hemorrhages or detachment even at a high acceleration of 1,000×g during pecking. To understand the mechanism of retinal injury and its resistance strategy, we put insight into the special ability of the woodpecker to protect the retina against damage under acceleration–deceleration impact. In this study, the structural and mechanical differences on the eyes of the woodpecker and human were analyzed quantitatively based on anatomical observation. We developed finite element eye models of the woodpecker and human to evaluate the dynamic response of the retina to the shaking load obtained from experimental data. Moreover, several structural parameters and mechanical conditions were exchanged between the woodpecker and human to evaluate their effects on retinal injury in SBS. The simulation results indicated that scleral ossification, lack of vitreoretinal attachment, and rotational acceleration–deceleration impact loading in a woodpecker contribute to the resistance to retinal injuries during pecking. The above mentioned special physical structures and mechanical behavior can distribute the high strain in the posterior segment of the woodpecker’s retina, which decrease the risk of retinal injury to SBS. | Shan Lu Xingyu Fan Sijian Liu Xiaoyu Liu Lizhen Wang | 2020 | Science China(Life Sciences)2020，63，4： | 1 |

| 10 | Molecular game theory for a toxin-dominant food chain model显示文摘Animal toxins that are used to subdue prey and deter predators act as the key drivers in natural food chains and ecosystems.However,the predators of venomous animals may exploit feeding adaptation strategies to overcome toxins their prey produce.Much remains unknown about the genetic and molecular game process in the toxin-dominant food chain model.Here,we show an evolutionary strategy in different trophic levels of scorpion-eating amphibians,scorpions and insects,representing each predation relationship in habitats dominated by the paralytic toxins of scorpions.For scorpions preying on insects,we found that the scorpion a-toxins irreversibly activate the skeletal muscle sodium channel of their prey(insect,BgNayl)through a membrane delivery mechanism and an efficient binding with the Asp/Lys-Tyr motif of BgNayl.However,in the predatory game between frogs and scorpions,with a single point mutation(Lys to Glu)in this motif of the frog's skeletal muscle sodium channel(fNay 1.4);fNay 1.4 breaks this interaction and diminishes muscular toxicity to the frog;thus,frogs can regularly prey on scorpions without showing paralysis.Interestingly,this molecular strategy also has been employed by some other scorpion-eating amphibians,especially anurans.In contrast to these amphibians;the Asp/Lys-Tyr motifs are structurally and functionally conserved in other animals that do not prey on scorpions.Together,our findings elucidate the protein-protein interacting mechanism of a toxin-dominant predator-prey system,implying the evolutionary game theory at a molecular level. | Bowen Li Jonathan R.Silva Xiancui Lu Lei Luo t Yunfei Wang Lizhen Xu Aerziguli Aierken Zhanserik Shynykul Peter Muiruri Kamau Anna Luo Jian Yang Deyuan Su Fan Yang Jianmin Cui Shilong Yang Ren Lai | 2019 | National Science Review2019，6，6： | 1 |
| 11 | A critical review on the biomechanical study of cervical interbody fusion cage显示文摘Anterior Cervical Discectomy and Fusion(ACDF)is the preferred surgical method for the treatment of severe cervical degenerative disc disease with radiculopathy or myelopathy,of which the objectives are to restore the normal height of intervertebral space and cervical lordosis through the implantation of cervical interbody fusion cage.The biomechanical performance of a cervical interbody fusion cage,which plays a significant role in achieving the goals of ACDF,is influenced by multiple factors.In this paper,various studies focusing on the biomechanical performance of cervical interbody fusion cage are reviewed.Furthermore,the research methods,biomechanical evaluation parameters and data analysis methods of these research are analyzed in order to obtain a comprehensive understanding of the progress and limitations of research in this field.Although great progress has been made to clarify the biomechanical behaviors of cervical interbody fusion cage,there is still controversy regarding the issues such as the relative contribution of multiple factors to the performance of cage,the interactions among these factors,as well as whether the effects of factors change with the process of intervertebral osseointegration and so on.Thus,investigations are still needed to improve the comprehension of cervical interbody fusion cage biomechanically. | Huiwen Huang Jinglong Liu Lizhen Wang Yubo Fan | 2021 | Medicine in Novel Technology and Devices2021，，3： | 1 |

| 20 | Double carbon decorated lithium titanate as anode material with high rate performance for lithium-ion batteries显示文摘Spinel lithium titanate(Li_4Ti_5O_(12)) has the advantages of structural stability, however it suffers the disadvantages of low lithium-ion diffusion coefficient as well as low conductivity. In order to solve issues,we reported a simple method to prepare carbon-coated Li_4Ti_5O_(12)/CNTs(C@Li_4Ti_5O_(12)/CNTs) using stearic acid as surfactant and carbon source to prepare carbon coated nanosized particles. The obtained Li_4Ti_5O_(12) particles of 100 nm in size are coated with the carbon layers pyrolyzed from stearic acid and dispersed in CNTs matrix homogeneously. These results show that the synthesized C@Li_4Ti_5O_(12)/CNTs material used as anode materials for lithium ion batteries, presenting a better high-rate performance(147 m Ahg^(-1)at20 C). The key factors affecting the high-rate properties of the C@Li_4Ti_5O_(12)/CNTs composite may be related to the synergistic effects of the CNTs matrix and the carbon- coating layers with conductivity enhancement. Additionally, the amorphous carbon coating is an effective route to ameliorate the rate capability of Li_4Ti_5O_(12)/CNTs. | Haifang Ni Weili Song Lizhen Fan | 2016 | Progress in Natural Science:Materials International2016，26，3： | 0 |
