1Crack monitoring method based on Cu coating sensor and electrical potential technique for metal structure显示文摘Advanced crack monitoring technique is the cornerstone of aircraft structural health monitoring.To achieve real-time crack monitoring of aircraft metal structures in the course of service,a new crack monitoring method is proposed based on Cu coating sensor and electrical potential difference principle.Firstly,insulation treatment process was used to prepare a dielectric layer on structural substrate,such as an anodizing layer on 2A12-T4 aluminum alloy substrate,and then a Cu coating crack monitoring sensor was deposited on the structure fatigue critical parts by pulsed bias arc ion plating technology.Secondly,the damage consistency of the Cu coating sensor and2A12-T4 aluminum alloy substrate was investigated by static tensile experiment and fatigue test.The results show that strain values of the coating sensor and the 2A12-T4 aluminum alloy substrate measured by strain gauges are highly coincident in static tensile experiment and the sensor has excellent fatigue damage consistency with the substrate.Thirdly,the fatigue performance discrepancy between samples with the coating sensor and original samples was investigated.The result shows that there is no obvious negative influence on the fatigue performance of the 2A12-T4 aluminum alloy after preparing the Cu coating sensor on its surface.Finally,crack monitoring experiment was carried out with the Cu coating sensor.The experimental results indicate that the sensor is sensitive to crack,and crack origination and propagation can be monitored effectively through analyzing the change of electrical potential values of the coating sensor.Hou Bo He Yuting Cui Ronghong Gao Chao Zhang Teng 2015Chinese Journal of Aeronautics2015,28,3:10
2Special interstitial route can transport nanoparticles to the brain bypassing the blood-brain barrier显示文摘Nowadays,nanoparticles(NPs)are considered to be ideal tools for bioimaging and drug delivery.Although increasing research has focused on NP biodistribution,transportation in the interstitial architecture has been neglected.The entire body is connected by the interstitial architecture,which can provide a long-range and direct pathway for NP biodistribution in a nonvascular system.In this study,we report that 10-nm gold NPs injected directly into the interstitial architecture of the tarsal tunnel of rats(intervaginal space injection(ISI))were delivered to the brain without crossing the blood-brain barrier.Furthermore,NaGdF4 nanoparticles were used to explore the transportation route by magnetic resonance imaging.The results demonstrated that,after ISI,the NaGdF4 nanoparticles were transported through the perivascular interstitial space of the carotid arteries and brain vessels to the brain.This is a special nonvascular transportation route like a stream based on the interstitial architecture that provides an alternative pathway for NP biodistribution.Nan Hu Xiaoli Shi Qiang Zhang Wentao Liu Yuting Zhu Yuqing Wang Yi Hou Yinglu Ji Yupeng Cao Qian Zeng Zhuo Ao Quanmei Sun Xiaohan Zhou Xiaochun Wu Dong Han 2019Nano Research2019,12,11:2

4Study on the Control Strategy of Free Piston Expander-Linear Generator Used for Organic Rankine Cycle Waste Heat Recovery显示文摘This study presents a free piston expander-linear generator (FPE-LG) for engine waste heat recovery.The control strategies based on displacement (control strategy A) and valve timings (control strategy B) are proposed.The operation and output characteristics with different control strategies are conducted.The results show that control strategy has significant effect on the FPE-LG performance.When FPE-LG operates with control strategy A,the operation frequency is determined by the intake pressure,advanced exhaust duration,fixed position point and external load resistance,whereas it is only related with the intake/exhaust time and advanced exhaust duration (ta) for control strategy B.The external load resistance has slight influence on the stroke length for these two control strategies.For control strategy A,when advanced exhaust duration is more than 40 ms,the stroke length rises with the intake pressure,whereas it first rises and then reduces when advanced exhaust duration is less than 40 ms.There exist the optimal external load resistance and advanced exhaust duration to achieve the maximum power output with control strategy A,whereas the average power output reduces with the increasing advanced exhaust duration when using control strategy B.Stable operation and high power output can be obtained by using different control strategies and adjusting relevant operation parameters.HOU Xiaochen ZHANG Hongguang ZHAO Tenglong SHI Xin XU Yonghong LI Jian GE Zhong ZHANG Jun WU Yuting 2021Journal of Thermal Science2021,30,2:1

6Investigation of hemostatic effect of Spleeninvigorating,Qi-replenishing and Bloodarresting Formula on simvastatin-induced zebrafish hemorrhage model显示文摘Blood-arresting Formula on simvastatin-induced zebrafish hemorrhage model compared with that of the Heat-clearing and Blood-cooling Formula.Methods:AB strain wild type zebrafish were treated with 0.5 mM simvastatin for 24 hours to establish the zebrafish hemorrhage model.Under strictly blind experimental conditions,the zebrafish were then treated with experimental agents in different concentration within the maximum non-lethal dose.The intervention effect of the Spleen-invigorating,Qi-replenishing and Blood-arresting Formula was comprehensively assessed by examining the main observational parameters such as the bleeding reduction rate and hemostatic rate while referring to the additional parameters such as blood flow,improvement rate of blood flow,velocity of movement,improvement rate of motion under spleen-qi deficiency.Results:Hemostatic effect:The bleeding rate and hemostatic rate in the zebrafish were respectively,30%,15%,45%,40%and 60%,80%,40%,47%when equal concentration of 500 mg/mL,1000 mg/mL were used.This showed that the experimental herbs B1 was superior to B2 in decreasing the bleeding rate and improving hemostatic effect in the zebrafish.Improvement of blood flow:With equal concentration,the experimental herb B1 was superior to B2 in increasing the blood flow and improvement rate of blood flow in hemorrhagic zebrafish.Promotion of the improvement of motion:With equal concentration of 500 mg/mL and 1000 mg/mL,the experimental herb B1 was superior to B2 in promoting the velocity of motion in the zebrafish and promoting the improvement rate of motion.Conclusion:The manifestations of simvastatin-induced zebrafish hemorrhage are basically similar to that of failure of the spleen to control blood in human beings.The Spleeninvigorating,Qi-replenishing and Blood-arresting Formula has good hemostatic effect on simvastatin-induced hemorrhage in the zebrafish.It also boasts the functions of improving blood flow and velocity of motion in the hemorrhagic zebrafish.Such a conclusion provides the experimental basis for the treatment of the syndrome of failure of the spleen to control blood by this formula.Yuting Chu Ling Zhang Xiaoyu Zhu Yayue Zhang Bo Xia Li Hou Rushun Song Tiantian Li Chunqi Li Qing Dong a Xinyi Chen 2016Journal of Traditional Chinese Medical Sciences2016,3,4:1

8Constructions of ROS-responsive titanium-hydroxyapatite implant for mesenchymal stem cell recruitment in peri-implant space and bone formation in osteoporosis microenvironment显示文摘To solve the issue of unsatisfactory recruitment of mesenchymal stem cells(MSCs)around implant in osteoporotic fractures,we fabricated a ROS-responsive system on titanium surface through hydroxyapatite coating and biomolecule grafting.The porous hydroxyapatite and phosphorylated osteogenic growth peptides(p-OGP)were introduced onto titanium surface to synergistically improve osteogenic differentiation of MSCs.After the p-OGPpromoted expression of osteogenic related proteins,the calcium and phosphate ions were released through the degradation of hydroxyapatite and integrated into bone tissues to boost the mineralization of bone matrix.The ROS-triggered release of DNA aptamer(Apt)19S in the osteoporotic microenvironment guides MSC migration to implant site due to its high affinity with alkaline phosphatase on the membrane of MSCs.Once MSCs reached the implant interface,their osteogenic differentiation potential was enhanced by p-OGP and hydroxyapatite to promote bone regeneration.The study here provided a simple and novel strategy to prepare functional titanium implants for osteoporotic bone fracture repair.Maohua Chen Yuting Sun Yanhua Hou Zhong Luo Menghuan Li Yujia Wei Maowen Chen Lu Tan Kaiyong Cai Yan Hu 2022Bioactive Materials2022,7,12:1
9Accuracy evaluation of two precipitation datasets over upper reach of Heihe River Basin, northwestern China显示文摘As an important forcing data for hydrologic models, precipitation has significant effects on model simulation. The China Meteorological Forcing Dataset(ITP) and Global Land Data Assimilation System(GLDAS) precipitation data are the two commonly used data sources in the Heihe River Basin(HRB). This paper focused on evaluating the accuracy of these two precipitation datasets. A set of metrics were developed to characterize the trend, magnitude, annual allocation, event matching, frequency, and spatial distribution of the two datasets. Meanwhile, such accuracy evaluation was performed at various scales, i.e., daily, monthly, and yearly. By comparing with observations, this study concluded that: first, both ITP and GLDAS precipitation data well represented the trends at corresponding sites, and GLDAS underestimated precipitation in most regions except the east tributary headwater region; second, unusual annual precipitation distribution was observed in both datasets with overestimation of precipitation in May through September and GLDAS appeared to be much severe; third, the ITP data seriously over-predicted the precipitation events; fourth, the ITP data have better spatial distribution than GLDAS in the upper reach area of HRB. Overall, we recommended ITP precipitation data for the land surface study in the upper reach of HRB.SiWei He ZhuoTong Nan YuTing Hou 2015Research in Cold and Arid Regions2015,7,2:1
10Foliar applications of various nitrogen(N)forms to winter wheat affect grain protein accumulation and quality via N metabolism and remobilization显示文摘Foliar nitrogen(N)application is an effective strategy to improve protein content and quality in wheat kernels,but the specific effects of N forms remain unclear.In a two-year field study,foliar application of various N forms(NO_(3)^(-),urea,NH_(4)^(+))at anthesis was performed to measure their effects on wheat grain protein accumulation,quality formation,and the underlying mechanisms.Foliar application of three N forms showed varying effects in improving grain gluten proteins and quality traits.Under NH_(4)^(+) application,there was more post-anthesis N uptake for grain filling,with relatively strong increase in enzyme activities and gene expression associated with N metabolism in flag leaves at 8–20 days after anthesis(DAA),whereas its promotion of grain N metabolism became weaker after 20 DAA than those under NO_(3)^(-) and urea treatments.More N was remobilized from source organs to grain under treatment with foliar NO_(3)^(-) and urea.Genes controlling the synthesis of gluten protein and disulfide bonds were upregulated by NO_(3)^(-) and urea at 20–28 DAA,contributing to increased grain protein content and quality.Overall,foliar applications of NO_(3)^(-) and urea were more effective than those of NH_(4)^(+) in increasing grain N filling.These findings show that manipulating the source–sink relationship by reinforcing grain N metabolism and N remobilization is critical for optimizing grain protein accumulation and quality formation.Xiaokang Lyu Yang Liu Na Li Liban Ku Yuting Hou Xiaoxia Wen 2022The Crop Journal2022,10,4:1
11Nano-capillary induced assemble of quantum dots on perovskite grain boundaries for efficient and stable perovskite solar cells显示文摘In recent years, perovskite solar cells(PSCs) have propelled into the limelight owing to rapid development of efficiency;however, the abundant defects at the perovskite grain boundaries result in unwanted energy loss and structural degradation. Here, the grain boundaries of perovskite polycrystalline films have been found to act as nanocapillaries for capturing perovskite quantum dots(PQDs), which enable the conformal assemble of PQDs at the top interspace between perovskite grains. The existence of PQDs passivated the surface defects, optimized the interfacial band alignments, and ultimately improved the power conversion efficiency from 19.27% to 22.47% in inverted PSCs. Our findings open up the possibility of selective assembly and structural modulation of the perovskite nanostructures towards efficient and stable PSCs.Miaoyu Lin Jingjing He Xinyi Liu Qing Li Zhanpeng Wei Yuting Sun Xuesong Leng Mengjiong Chen Zhuhui Xia Yu Peng Qiang Niu Shuang Yang Yu Hou 2023Journal of Energy Chemistry2023,,8:0
12Simulation and design of a heat-integrated double-effect reactive distillation process for propylene glycol methyl ether production显示文摘A double-effect reactive distillation(DERD)process was proposed for the production of propylene glycol methyl ether from propylene oxide and methanol to overcome the shortcoming of low selectivity and high-energy consumption in the tubular plug-flow reactor.A single-column reactive distillation(RD)process was conducted under optimized operating conditions based on sensitivity analysis as a reference.The results demonstrated that the proposed DERD process is able to achieve more than 95%selectivity of the desired product.After that,a design approach of the DERD process with an objective of the minimum operating cost was proposed to achieve further energy savings in the RD process.The proposed DERD configuration can provide a large energy-savings by totally utilization of the overhead vapor steam in the high-pressure RD column.A comparison of the single-column RD process revealed that the proposed DERD process can reduce the operating cost and the total annual cost of 25.3%and 30.7%,respectively,even though the total capital cost of DERD process is larger than that of the RD process.Ran An Shengxin Chen Shun Hou Yuting Zhu Chunhu Li Xinbao Zhu Ruixia Liu Weizhong An 2022Chinese Journal of Chemical Engineering2022,,12:0
13Strategies for Improving Public Transportation Accessibility in Beijing's Urban Regeneration from an Inclusive Perspective: Inspirations from Paris's Experience显示文摘As China’s urbanization has transformed from extensive development to 'refined operation,' urban regeneration is more significant. This paper analyzes changes in research perspectives of urban regeneration in recent years at home and abroad and the innovative concept of inclusive development proposed in the context of globalization, finding that the connotation of urban regeneration in European countries has been gradually enriched in order to promote social integration. Based on this, the paper examines how Paris, the first European city, combined inclusive development and urban regeneration and addressed social integration and equity in urban regeneration by taking accessibility as a key point in solving the most fundamental transportation problems. Based on lessons learned from Paris in developing a barrier-free transportation system, it proposes specific optimization strategies at the micro level in accordance with the status quo of public transportation accessibility in Beijing’s urban regeneration.Hou Yuting Li Min(译) Tang Yan(校) 2021China City Planning Review2021,30,3:0
