| 1 | 3D-Printed Superhydrophobic and Magnetic Device That Can Self-Powered Sense A Tiny Droplet Impact显示文摘Three-dimensional(3D)-printed magnetic soft architectures have attracted extensive attention and research from the engineering and material fields.The force-driven shape deformation of such architectures causes a change in the magnetic field distribution,indicating the capability to convert mechanical energy to electricity.Herein,we fabricate a flexible superhydrophobic and magnetic device by integrating two kinds of 3D printing approaches.The 3D-printed magnetic device(3DMD)exhibits a long-term stable mechanoelectrical conversion capacity under consecutive water droplet dripping.The output current of the 3DMD is higher than that of records in the existing literature.Combined with Maxwell numerical simulation,the mechanoelectrical conversion mechanism of the 3DMD is investigated,further guiding regulation of the diverse parameters.Moreover,three 3DMDs are integrated to light up a commercial light-emitting diode(LED)by a stream of collected rainwater.Such a combined design incorporating energy conversion is believed to promisingly motive advances in the 3D printing field. | Xuan Zhang Qi Wang Ruiping Zou Bo Song Chunze Yan Yusheng Shi Bin Su | 2022 | Engineering2022，8，8： | 4 |
| 2 | Low intensity near-infrared light promotes bone regeneration via circadian clock protein cryptochrome 1显示文摘Bone regeneration remains a great clinical challenge. Low intensity near-infrared(NIR) light showed strong potential to promote tissue regeneration, offering a promising strategy for bone defect regeneration. However, the effect and underlying mechanism of NIR on bone regeneration remain unclear. We demonstrated that bone regeneration in the rat skull defect model was significantly accelerated with low-intensity NIR stimulation. In vitro studies showed that NIR stimulation could promote the osteoblast differentiation in bone mesenchymal stem cells(BMSCs) and MC3T3-E1 cells, which was associated with increased ubiquitination of the core circadian clock protein Cryptochrome 1(CRY1) in the nucleus. We found that the reduction of CRY1 induced by NIR light activated the bone morphogenetic protein(BMP) signaling pathways, promoting SMAD1/5/9 phosphorylation and increasing the expression levels of Runx2 and Osterix. NIR light treatment may act through sodium voltage-gated channel Scn4a, which may be a potential responder of NIR light to accelerate bone regeneration. Together, these findings suggest that low-intensity NIR light may promote in situ bone regeneration in a CRY1-dependent manner, providing a novel, efficient and non-invasive strategy to promote bone regeneration for clinical bone defects. | Jinfeng Peng Jiajia Zhao Qingming Tang Jinyu Wang Wencheng Song Xiaofeng Lu Xiaofei Huang Guangjin Chen Wenhao Zheng Luoying Zhang Yunyun Han Chunze Yan Qian Wan Lili Chen | 2022 | International Journal of Oral Science2022，14，4： | 2 |
| 3 | Three-dimensional biofabrication of an aragoniteenriched self-hardening bone graft substitute and assessment of its osteogenicity in vitro and in vivo显示文摘A self-hardening three-dimensional(3D)-porous composite bone graft consisting of 65 wt%hydroxyapatite(HA)and 35 wt%aragonite was fabricated using a 3D-Bioplotter®.New tetracalcium phosphate and dicalcium phosphate anhydrous/aragonite/gelatine paste formulae were developed to overcome the phase separation of the liquid and solid components.The mechanical properties,porosity,height and width stability of the end products were optimised through a systematic analysis of the fabrication processing parameters including printing pressure,printing speed and distance between strands.The resulting 3D-printed bone graft was confirmed to be a mixture of HA and aragonite by X-ray diffraction,Fourier transform infrared spectroscopy and energy dispersive X-ray spectroscopy.The compression strength of HA/aragonite was between 0.56 and 2.49 MPa.Cytotoxicity was assessed using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide(MTT)assay in vitro.The osteogenicity of HA/aragonite was evaluated in vitro by alkaline phosphatase assay using human umbilical cord matrix mesenchymal stem cells,and in vivo by juxtapositional implantation between the tibia and the anterior tibialis muscle in rats.The results showed that the scaffold was not toxic and supported osteogenic differentiation in vitro.HA/aragonite stimulated new bone formation that bridged host bone and intramuscular implants in vivo.We conclude that HA/aragonite is a biodegradable and conductive bone formation biomaterial that stimulates bone regeneration.Since this material is formed near 37°C,it will have great potential for incorporating bioactive molecules to suit personalised application;however,further study of its biodegradation and osteogenic capacity is warranted.The study was approved by the Animal Ethical Committee at Tongji Medical School,Huazhong University of Science and Technology(IACUC No.738)on October 1,2017. | Yunsong Shi Ruijun He Xiangyu Deng Zengwu Shao Davide Deganello Chunze Yan Zhidao Xia | 2020 | Biomaterials Translational2020，1，1： | 2 |

| 6 | Mechanical properties and microstructure characteristics of lattice-surfaced PEEK cage fabricated by high-temperature laser powder bed fusion显示文摘Porous structure design on the contact surface is crucial to promote the osseointegration of the intervertebral cage while preventing subsidence and displacement.However,the stress response will undergo significant changes for the current random porous cages,which can directly affect the mechanical properties and long-term usability.Here,this paper proposed a newly designed polyetheretherketone(PEEK)cage with the triply periodic minimal surface(TPMS)-structured lattice surfaces to provide tailored 3 D microporosity and studied the mechanical performance,stress/strain responses,and microstructure changes in depth.The lattice-surfaced PEEK cage mainly exhibits a multiple-point-plane stress transfer mechanism.The compression modulus and elastic limit can be adjusted by controlling the area of the Diamond TPMS surface while the energy absorption efficiency remains stable.The microstructure of high-strength PEEK is featured by the radial pattern morphology.Meanwhile,the double-stranded orthorhombic phase is more ordered,and the benzene plane subunit and lattice volume become more expanded. | Peng Chen Jin Su Haoze Wang Lei Yang Haosong Cai Maoyuan Li Zhaoqing Li Jie Liu Shifeng Wen Yan Zhou Chunze Yan Yusheng Shi | 2022 | Journal of Materials Science & Technology2022，，30： | 1 |

| 10 | Large Curvature Folding Strategies of Butterfly Proboscis显示文摘Due to its real-time control,high folding ratio,and structure self-locking,flexible large curvature self-folding devices have broad application prospects,such as foldable human implants,flexible electronics,and flexible robots.Driven by this background,flexible large curvature folding butterfly(Polyura eudamippus)proboscises were studied in this work.The folding ratio of the proboscises was about 15.The curvature of coiled proboscises ranged from about 150 m_1 to 880 m The external and internal structures of the proboscises were studied by different methods.Three main strategies for large-curvature folding of proboscises were identified:a gradual decrease in thickness,a lower elastic modulus,and(most importantly)large numbers of regular corrugated cracks arranged on the surface.These corrugated cracks can effectively accommodate the coiled strain and provide space for the large curvature folding of proboscises.Finally,a 4D printed coiled sample with corrugated cracks was fabricated to mimic the proboscises stretching process.Large-curvature folding strategies,based on these proboscises,provide insights for the biomimetic design of artificial highly folded components. | Daobing Chen Honglie Song Qingping Liu Jie Gan Yang Liu Keyu Che' Chong Wang Shifeng Wen Yan Zhou Chunze Yan Junqiu Zhang Yusheng Shi Zhiwu Han | 2020 | Journal of Bionic Engineering2020，17，6： | 1 |

| 19 | Multimaterial additive manufacturing manipulator for fabricating magnetoelectric pressure sensors显示文摘The simultaneous placement of different types of materials including polymers,ceramics,and metals,in their desired positions could be adopted to manufacture end-use devices/apparatuses with diverse functionalities and significantly reduce the fabrication cost and time.However,existing additive manufacturing(AM)approaches can only treat one material species at a time due to their intrinsic working mechanisms.Here we develop an AM manipulator for manufacturing a wide variety of material species,including polymers,ceramics,and metals,through a multifilament transport strategy assisted by laser power.The six-jaw manipulator contains three pairs of filament delivering/cutting systems for transporting diverse materials and a beam of tunable laser as the thermal source.The whole apparatus is integrated into a robotic manipulator to create a multifreedom manufacturing platform.With this innovation,products with multiple material species and desired complex geometries can be fabricated on demand.Furthermore,we synthesize a multimaterial(polymer/ceramic/metal)printed magnetoelectric pressure sensor that can convert applied mechanical forces to electricity and maintain efficiency even after undergoing 10000 cycles of pressure/recovery.With this multimaterial filament transport and laser manufacturing strategy,our AM manipulator exhibits promising application in the advanced manufacturing of embedded electronics,sensors,soft robotics,and customizable medical devices. | LIU ZhuFeng LI ZhaoQing WANG Qi WANG Yan YANG Lei NIE Xiang GENG Peng WU ZhenHua TANG SiHan YANG Lei WU HongZhi SHI YunSong CHEN Peng SU Bin ZHANG LiChao YAN ChunZe SHI YuSheng | 2022 | Science China(Technological Sciences)2022，65，11： | 1 |
