| 2 | Centrifuge experiment on the penetration test for evaluating undrained strength of deep-sea surface soils显示文摘Rapid advances in deep-sea mining engineering have created an urgent need for the accurate evaluation of the undrained strength of marine soils,especially surface soils.Significant achievements have been made using full-flow penetration penetrometers to evaluate marine soil strength in the deep penetration;however,a method considering the effect of ambient water on the surface penetration needs to be established urgently.In this study,penetrometers with multiple probes were developed and used to conduct centrifuge experiments on South China Sea soil and kaolin clay.First,the forces on the probes throughout the penetration process were systematically analyzed and quantified.Second,the spatial influence zone was determined by capturing the resistance changes and sample crack development,and the penetration depth for a sample to reach a stable failure mode was given.Third,the vane shear strength was used to invert the penetration resistance factor of the ball and determine the range of the penetration resistance factor values.Furthermore,a methodology to determine the penetration resistance factors for surface marine soils was established.Finally,the effect of the water cavity above various probes in the surface penetration was used to formulate an internal mechanism for variations in the penetration resistance factor. | Xingsen Guo Tingkai Nian Wei Zhao Zhongde Gu Chunpeng Liu Xiaolei Liu Yonggang Jia | 2022 | International Journal of Mining Science and Technology2022，32，2： | 2 |
| 3 | A novel conceptual design of a biomimetic oral implant and its biomechanical effect on the repairment of a large mandibular defect显示文摘This study aimed to propose a novel biomimetic design strategy of an oral implant and to numerically examine its biomechanical effect according to clinical interests.The designed implant conceptually mimicked the morphology and elastic modulus of the mandibular bone.Basing on a CT-image-based patient-specific reconstruction of the tumor-excised mandible,the biomechanical effects of the implants with three materials(PEEK/n-HA/CF,PEEK/HA and Ti6Al4V),two surgical conditions(removed and retained muscles),and two postoperative stages(early and late)were fully investigated by a static finite element analysis.Moreover,according to clinical interests(e.g.failure and stability of the implant and rivets),maximum von Mises stresses and strains of the implant and rivets,maximum implant-bone gap in the early postoperative stage,and maximum von Mises stress of the mandible were mainly analyzed.The results showed that the implant composed of Ti6Al4V material was suitable for the current design strategy with respect to the other two PEEK-based materials.Although the implants in the muscle-retained surgical condition had relative greater indices compared to the muscle-removed surgical condition,the index difference between the two conditions was slight.The biomechanical indices indicating the failure and loosening risks of implant and rivets were much reduced in the late postoperative stage with respect to the early postoperative stage due to the osteointegration at the implant-bone interface.Generally,the proposed novel design strategy could be useful to guide the design of the oral implant addressing different implant materials and surgical conditions,and further made proper suggestion to clinicians and patients. | Yongheng Li Yuanbin Hu Heming Chen Xiangfeng Meng Du Chen Hongcheng Gu Qiang Chen Zhongde Mu Zhiyong Li | 2022 | Medicine in Novel Technology and Devices2022，，3： | 0 |
| 4 | Robust Carbonated Structural Color Barcodes with Ultralow Ontology Fluorescence as Biomimic Culture Platform显示文摘Photonic crystal(PC)barcodes are a new type of spectrum-encoding microcarriers used in multiplex high-throughput bioassays,such as broad analysis of biomarkers for clinical diagnosis,gene expression,and cell culture.Unfortunately,most of these existing PC barcodes suffered from undesired features,including difficult spectrum-signal acquisition,weak mechanical strength,and high ontology fluorescence,which limited their development to real applications.To address these limitations,we report a new type of structural color-encoded PC barcodes.The barcodes are fabricated by the assembly of monodisperse polydopamine-(PDA-)coated silica(PDA@SiO_(2))nanoparticles using a droplet-based microfluidic technique and followed by pyrolysis of PDA@SiO_(2)(C@SiO_(2))barcodes.Because of the templated carbonization of adhesive PDA,the prepared C@SiO_(2)PC beads were endowed with simultaneous easy-to-identify structural color,high mechanical strength,and ultralow ontology fluorescence.We demonstrated that the structural colored C@SiO_(2)barcodes not only maintained a high structural stability and good biocompatibility during the coculturing with fibroblasts and tumor cells capture but also achieved an enhanced fluorescentreading signal-to-noise ratio in the fluorescence-reading detection.These features make the C@SiO_(2)PC barcodes versatile for expansive application in fluorescence-reading-based multibioassays. | Panmiao Liu Zhongde Mu Muhuo Ji Xiaojiang Liu Hanwen Gu Yi Peng Jianjun Yang Zhuoying Xie Fuyin Zheng | 2021 | Research2021，，1： | 0 |
