3In 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 2022Bioactive Materials2022,7,1:1

11Multi-site anchoring of single-molecule for efficient and stable perovskite solar cells with lead shielding显示文摘The emergence of perovskite solar cells(PSCs) has greatly promoted the progress of photovoltaic technologies.The rapid development of PSCs has been driven by the advances in optimizing perovskite films and their adjacent interfaces.However,the polycrystalline perovskite layers in most highly efficient PSCs still contain various defects that greatly limit photovoltaic performance and stability of the devices.Herein,we introduce a multifunctional additive ethylene diamine tetra methylene phosphonic sodium(EDTMPS) with multiple anchor points into the precursor of perovskite to improve the efficiency and stability of PSCs and provide in-situ protection of lead leakage.The addition of EDTMPS acts as a crystal growth controller and passivation agent for perovskite films,thereby slowing down the crystallization rate of the film and obtaining high-quality perovskite films.Our study also provides an insight into how the modifier modulate the interfacial energy level arrangement as well as affect transfer of charge carriers and their recombination under photoinduced excitation.As a result,the power conversion efficiency(PCE) of single subcell with a working area of 0.255 cm^(2) increases significantly from 20.03% to 23.37%.Moreover,we obtained a PCE of 19.16% for the 25 cm^(2) module.Importantly,the unencapsulated EDTMP-modified PSCs exhibit better operational and thermal stability,as well as in-situ absorption of leaked lead ions.Zhengyan He Shufang Zhang Yushuang Gao Quanming Geng Xiangrui Jia Shuo Yang Zhiqiang Zhang Yanpu Zheng Yanqiang Hu Changlin Yao Qi Zhang 2023Journal of Energy Chemistry2023,,12:0
12Design and Experimental Testing of an Electric Field-Driven Droplet Injection Device显示文摘The properties of droplets produced by existing on-demand injection systems are typically determined by the nozzle diameter,i.e.,only droplets with size larger than this diameter can be obtained.To solve this problem,a system for electricfield-driven droplet injection and deposition was developed,and the related performances were compared with those of a standard pneumatic system.The results show that the diameter of droplets gen-erated accordingly can be significantly smaller than the nozzle diameter.In particular,the effects of frequency and duty ratio on the number of droplets were studied by assuming microcrystalline wax as work material.A deposi-tion matrix was obtained by using a nozzle with a diameter of 200μm.The average diameter of the matrix was 80.17μm with a standard deviation of 2.65μm and the average spacing was 301.25μm with a standard deviation of 6.80μm.Four deposition states after droplet injection were considered and verified under different velocities of F60,F10,F3,and F0.We also provide an explanation for the existence of a series of inclined columns showing up during the deposition processs.Fulai Cao Yanpu Chao Hao Yi Shuai Lu Chengshui Guo 2023Fluid Dynamics & Materials Processing2023,19,11:0
13Experimental Analysis of a Pneumatic Drop-on-Demand(DOD)Injection Technology for 3D Printing Using a Gallium-Indium Alloy显示文摘Many liquid metals have a high boiling point,strong electrical conductivity,high thermal conductivity,and nontoxic properties,which make them ideal targets for applications in different fields such as optics,microcircuits,electronic switches,micro-electromechanical System(MEMS)devices and 3D printing manufacturing.However,owing to the generally high surface tension of these liquids,achieving uniform micro-droplets is often a challenge due to the inherent difficulties in controlling their size and shape.In this study,a gallium indium alloy(GaIn24.5)has been used in combination with a pneumatic drop-on-demand(DOD)injection technology to carry out a series of experiments.The micro-droplet forming process has been explored for different pressure and pulse width conditions.Uniform metal droplets(diameter 1080μm)have been obtained with a 1.5 kPa jet pressure,100 ms pulse width,and 50%duty ratio.The standard deviation of the measured metal droplets diameter has been found to be approximately 20μm.Yanpu Chao Hao Yi 2021Fluid Dynamics & Materials Processing2021,17,3:0
14Porous bio-high entropy alloy scaffolds fabricated by direct ink writing显示文摘Porous tantalum-titanium-niobium-zirconium(Ta-Ti-Nb-Zr)bio-high entropy alloy(bioHEA)scaffolds are fabricated using direct ink writing 3D printing technology in this study.A composite ink is prepared using four metal powders as raw materials:Ta,Ti,Nb and Zr.Ink extrusion is used to build 3D scaf-folds with interconnected porous structures at room temperature,which are then sintered in a vacuum environment.The interdiffusion of metal elements yields porous bioHEA scaffolds with a body-centered cubic(BCC)structure.The fabricated scaffolds have uniform compositions with a significant alloying ef-fect and good biocompatibility.The scaffolds have a compressive strength of 70.08-149.95 MPa and an elastic modulus of 0.18-0.64 GPa,indicating that the mechanical properties can be controlled over a wide range.The scaffolds have a compressive strength close to that of human cortical bone and thus meet the requirements for porous structure characteristics and biological and mechanical properties of orthopedic implants.Guangbin Zhao Xiaoxi Shao Qingxian Zhang Yanlong Wu Yaning Wang Xu Chen Hang Tian Yaxiong Liu Yanpu Liu Bingheng Lu 2023Journal of Materials Science & Technology2023,,26:0
15Plasma Lipidomic Subclasses and Risk of Hypertension in Middle-Aged and Elderly Chinese显示文摘While disrupted lipid metabolism is a well-established risk factor for hypertension in animal models,the links between various lipidomic signatures and hypertension in human studies remain unclear.We aimed to examine associations between plasma lipidomic profiles and prevalence of hypertension among 2248 community-living Chinese aged 50-70 years.Hypertension was defined according to 2020 International Society of Hypertension global hypertension practice guidelines and 2018 Chinese guidelines.In total,728 plasma lipidomic species were profiled using high-coverage targeted lipidomics.After multivariate adjustment,including lifestyle,body mass index,blood lipids,and sodium intake,110 metabolites from nine lipidomic subclasses showed significant associations with hypertension,among which phosphatidylethanolamines(PEs)had the strongest association.Eleven lipidomic signals for hypertension risk were further identified from the nine subclasses,including PE(18:0/18:2)(OR per SD,1.49;95%confidence intervals,1.30-1.69),phosphatidylcholine(PC)(18:0/18:2)(1.27;1.13-1.43),phosphatidylserine(18:0/18:0)(1.24;1.09-1.41),lysophosphatidylinositol(18:1)(1.17;1.06-1.29),triacylglycerol(52:5)(1.38;1.18-1.61),diacylglycerol(16:0/18:2)(1.42;1.19-1.69),dihydroceramide(24:0)(1.25;1.09-1.43),hydroxyl-sphingomyelins(SM[2OH])C34:1(1.19;1.07-1.33),lysophosphatidylcholine(20:1)(0.86;0.78-0.95),SM(OH)C38:1(0.87;0.79-0.96),and PC(18:2/20:1)(0.84;0.75-0.94).Principal component analysis also showed that a factor mainly containing specific PEs was positively associated with hypertension(1.20;1.09-1.33).Collectively,our study revealed that disturbances in multiple circulating lipidomic subclasses and signatures,especially PEs,were significantly associated with the prevalence of hypertension in middle-aged and elderly Chinese.Future studies are warranted to confirm our findings and determine the mechanisms underlying these associations.Zhenhua Niu Qingqing Wu Yaogan Luo Di Wang He Zheng Yanpu Wu Xiaowei Yang Rong Zeng Liang Sun Xu Lin 2022Phenomics2022,2,5:0
16Effects of igneous bodies on modification of modern slope morphology: Insights from the continental slope offshore Dongsha Islands, South China Sea显示文摘A statistical analysis for the morphological parameters extracted from numerous seismic profiles, and a highresolution seismic study of the southeastern slope of the Dongsha Islands(South China Sea) with water depth between approximately 500 and 3 100 m, has revealed the variation of morphological features due to the intrusion of igneous bodies and associated sedimentary processes. Three types of the continental slope are distinguished:(1) a rough and steep slope with multiple igneous bodies(Type 1),(2) a relatively smooth and gentle slope with the single igneous body(Type 2), and(3) a smooth and gentle slope without igneous bodies(Type 3). These igneous bodies, formed in the post-seafloor spreading of the South China Sea, are often characterized by high positive seismic amplitudes, and chaotic reflections with complex shapes. The igneous bodies in Type 1 separated the slope into two or more upper sub-sags and a lower main-sag, in which the sub-sags and main-sag could be filled with sediments transported by alongslope bottom currents at the same time. Whereas, the igneous body in Type 2 just separated the slope into an upper sub-sag and a lower main-sag, in which the sediments could be transported into the lower main-sag only after the upper sub-sag has been filled up. Type 3 represents a normal slope with common clinoform progradation. The modern slope morphologies in the study area are the results of adjustments of the continental slope due to the intrusion of igneous bodies and associated sedimentary processes. The distinctions among three types of modern slope morphologies indicate different depositional conditions and adjustments of slope morphologies.Chao Liang Xinong Xie Hua Wang Guangjian Zhong Entao Liu Ming Sun Hai Yi Chunyu Qin Haiyang Cao Jie He Yanpu Zhao 2019Acta Oceanologica Sinica2019,38,5:0
17Kansei Engineering Analysis of Purple-clay Teapot Based on Online Comment Data显示文摘Product form has become an important communication medium between designers and consumers.Therefore,the collection and analysis of consumer evaluation of products can provide an important reference index for product form design.In this paper,purpleclay teapot was taken as an example and comments of Tmall consumers were collected through web crawler,and the product image vocabulary was extracted to analyze the needs of users.Using the research method of Kansei Engineering,the semantic space of the modeling and image of purple-clay teapot was established,and the relationship between the modeling elements and the image of purple-clay teapot was searched,which could provide valuable reference for the modeling design of purple-clay teapot.Xinyu ZHANG Bin QI Yanpu YANG Xiaoming SUN 2019Research and Application of Materials Science2019,1,2:0
18Discharge characteristics of leader inception and development under 10 m long air gap—experimental observation and simulation results显示文摘The physical mechanism of leader formation and development is not well understood.In this study,we present experimental and simulation results obtained with a 10 m long air gap discharge.A 10 m outdoor discharge experiment is carried out to obtain the current,voltage,and optical image during the leader discharge process.Four different impulse voltages were applied to the rod‐plane gap.The measured current is used as an input for a plasma model,then the temperature and electric field could be calculated.The simulation results show that the temperature of the streamer stem during the dark period may exceed 2000 K.In addition,the critical charge required for leader initiation can be as low as 0.27μC for a 10 m air gap.The channel temperature is relatively stable in the process of leader development,which is maintained at about 4500 K.The electron density is about 0.5–3�1020 m-3,and the discharge channel conductivity fluctuates in the range of 1–10 S/m for the leader current between 1 and 2 A.A long dark period is tended to be associated with a higher injected charge by the first streamer.It is inferred that the voltage increments during the dark period play an important role in promoting streamer‐to‐leader transition,except for temperature and the injected charge.Changzhi Peng Xuzhu Dong Yanpu Zhao Zhijun Li Yu Zheng Xuekai Pei Lei Liu Bing Luo 2023High Voltage2023,8,6:0
