| 1 | Structure evolution of oxygen removal from porous carbon for optimizing supercapacitor performance显示文摘The presence of oxygen functional groups is detrimental to the capacitive performance of porous carbon electrode in organic electrolyte. In this regards, hydrogen thermal reduction has been demonstrated effective approach in removing the unstable surface oxygen while maintaining the high porosity of carbon matrix. However, the exact evolution mechanism of various oxygen species during this process, as well as the correlation with electrochemical properties, is still under development. Herein, biomass-based porous carbon is adopted as the model material to trace its structure evolution of oxygen removal under hydrogen thermal reduction process with the temperature range of 400–800 °C. The optimum microstructure with low oxygen content of 0.90% and proper pore size distribution was achieved at 700°C. XPS, TPRMS and Boehm titration results indicate that the oxygen elimination undergoes three distinctive stages(intermolecular dehydration, hydrogenation and decomposition reactions). The optimum microstructure with low oxygen content of 0.90% and proper pore size distribution was achieved at 700 °C. Benefiting from the stable electrochemical interface and the optimized porous structure, the as-obtained HAC-700 exhibit significantly suppressed self-discharge and leak current, with improved cycling stability, which is attributable to the stabilization of electrochemical interface between carbon surface and electrolyte. The result provides insights for rational design of surface chemistry for high-performance carbon electrode towards advanced energy storage. | Siting Yuan Xianhong Huang Hao Wang Lijing Xie Jiayao Cheng Qingqiang Kong Guohua Sun Cheng-Meng Chen | 2020 | Journal of Energy Chemistry2020,29,12: | 16 |
| 2 | Heyan Kuntai capsule versus dehydroepiandrosterone in treating Chinese patients with infertility caused by diminished ovarian reserve: a multicenter, randomized controlled trial显示文摘OBJECTIVE: To evaluate the clinical efficacy and safety of Heyan Kuntai capsule(HYKT) in treating women with infertility caused by diminished ovarian reserve(DOR).METHODS: One hundred eight eligible patientsfrom three Chinese hospitals were randomly divided into an HYKT treatment group(n = 55) or a dehydroepiandrosterone(DHEA) treatment group(n =53). Patients in the HYKT group were treated orally with four 0.5 g HYKT three times a day; patients in the DHEA group were treated with one 25.0 mg DHEA capsule three times a day. All patients were treated for 3 months and followed up over a3-month period.RESULTS: Of 108 patients, 12 dropped out: six from the HYKT group, and six from the DHEA group. Eleven patients got pregnant during the treatment. Serum anti-Müllerian hormone levels and antral follicle counts increased significantly in both groups after treatment(P < 0.05) especially in the HYKT group(P < 0.05). Serum follicle stimulating hormone(FSH) levels and FSH/luteinizing hormone ratios decreased(P < 0.05) with no significant difference between the two groups. Estradiol levels in the HYKT group and DHEA-sulfate levels in the DHEA group both increased(P < 0.05). The spontaneous pregnancy rates were 12% and 11% in the HYKT and DHEA groups, respectively(not significant). During the follow-up period, 16 patients in the HYKT group underwent in vitro fertilization-embryo transfer(IVF-ET) and the number of retrieved oocytes was(5.1 ± 1.8). In DHEA group, 20 patients underwent IVF-ET and the number of retrieved oocyte was(4.2 ± 1.9)(not significant); clinical pregnancy rates were 38% in the HYKT group and 20%in DHEA group(not significant). No significant adverse reactions were observed.CONCLUSION: HYKT can improve the ovarian re-serve and hormone levels in patients with infertility caused by DOR. Pregnancy rates after HYKT treatment were similar to those of DHEA treatment.HYKT might be an alternative to the treatment of infertility caused by DOR. | Gao Hui Xia Tian Ma Ruihong Zhao Zhimei Song Xueru Wang Baojuan Liu Lijing Han Kaimei Wang Guoqing Fu Yu Hao Guimin | 2017 | Journal of Traditional Chinese Medicine2017,37,4: | 14 |
| 3 | Regenerative Braking Strategy for Motor Hoist by Ultracapacitor显示文摘Rising concern in environmental issues on global scale has made energy saving in powered equipment a very important subject.In order to improve the energy efficiency and driving range of a motor hoist,a regenerative braking system is designed and discussed.The system takes a unique ultracapacitor-only approach to energy storage system.The bi-directional bride DC?DC converter which regulates current flow to and from the ultracapacitor operates in two modes:boost and buck,depending on the direction of the flow.In order to provide constant input and output current at the ultracapacitor,this system uses a double proportional-integral(PI) control strategy in regulating the duty cycle of PWM to the DC?DC converter.The permanent magnet synchronous motor(PWSM) drive system is also studied.The space vector pulse width modulation(SVPWM) technique,along with a two-closed-loop vector control model,is adopted after detailed analysis of PMSM characteristics.The overall model and control strategy for this regenerative braking system is ultimately built and simulated under the MATLAB and Simulink environment.A test platform is built to obtain experimental results.Analysis of the results reveals that more than half of the gravitational potential energy can be recovered by this system.Simulation and experimentation results testify the validity of the double PI control strategy for interface circuit of ultracapacitor and SVPWM strategy for PMSM. | BIAN Yongming ZHU Lijing LAN Hao LI Anhu XU Xinming | 2012 | Chinese Journal of Mechanical Engineering2012,25,2: | 7 |
| 4 | Comparative genomic and transcriptomic analyses uncover the molecular basis of high nitrogen-use efficiency in the wheat cultivar Kenong 9204显示文摘Studying the regulatory mechanisms that drive nitrogen-use efficiency(NUE)in crops is important for sustainable agriculture and environmental protection.In this study,we generated a high-quality genome assembly for the high-NUE wheat cultivar Kenong 9204 and systematically analyzed genes related to nitrogen uptake and metabolism.By comparative analyses,we found that the high-affinity nitrate transporter gene family had expanded in Triticeae.Further studies showed that subsequent functional differentiation endowed the expanded family members with saline inducibility,providing a genetic basis for improving the adaptability of wheat to nitrogen deficiency in various habitats.To explore the genetic and molecular mechanisms of high NUE,we compared genomic and transcriptomic data from the high-NUE cultivar Kenong 9204(KN9204)and the low-NUE cultivar Jing 411 and quantified their nitrogen accumulation under high-and low-nitrogen conditions.Compared with Jing 411,KN9204 absorbed significantly more nitrogen at the reproductive stage after shooting and accumulated it in the shoots and seeds.Transcriptome data analysis revealed that nitrogen deficiency clearly suppressed the expression of genes related to cell division in the young spike of Jing 411,whereas this suppression of gene expression was much lower in KN9204.In addition,KN9204 maintained relatively high expression of NPF genes for a longer time than Jing 411 during seed maturity.Physiological and transcriptome data revealed that KN9204 was more tolerant of nitrogen deficiency than Jing 411,especially at the reproductive stage.The high NUE of KN9204 is an integrated effect controlled at different levels.Taken together,our data provide new insights into the molecular mechanisms of NUE and important gene resources for improving wheat cultivars with a higher NUE trait. | Xiaoli Shi Fa Cui Xinyin Han Yilin He Long Zhao Na Zhang Hao Zhang Haidong Zhu Zhexin Liu Bin Ma Shusong Zheng Wei Zhang Jiajia Liu Xiaoli Fan Yaoqi Si Shuiquan Tian Jianqing Niu Huilan Wu Xuemei Liu Zhuo Chen Deyuan Meng Xiaoyan Wang Liqiang Song Lijing Sun Jie Han Hui Zhao Jun Ji Zhiguo Wang Xiaoyu He Ruilin Li Xuebin Chi Chengzhi Liang Beifang Niu Jun Xiao Junming Li Hong-Qing Ling | 2022 | Molecular Plant2022,15,9: | 6 |
| 5 | Analysis of the Internal Characteristics of a De ector Jet Servo Valve显示文摘In current research on deflector jet servo valves, the receiver pressure estimated using traditional two-dimensional simulation and theoretical calculation is always lower than the experimental data; therefore, credible information about the flow field in the prestage part of the valve can hardly be obtained. To investigate this issue and understand the internal characteristics of the deflector jet valve, a realistic numerical model is constructed and a three-dimensional simulation carried out that displays a complex flow pattern in the deflector jet structure. Then six phases of the flow pattern are presented, and the defects of the two-dimensional simulation are revealed. Based on the simulation results, it is found that the jet in the deflector has a longer core area and the fluid near the shunt wedge cannot resist the impact of the high-speed fluid. Therefore, two assumptions about the flow distribution are presented by which to construct a more complete theoretical model. The receiver pressure and prestage pressure gain are significantly enhanced in the calculations. Finally, special experiments on the prestage of the servo valve are performed, and the pressure performance of the numerical simulation and the theoretical calculation agree well with the experimental data. Finally, the internal mechanism described by the theoretical and numerical models is verified. From this research,more accurate numerical and theoretical models are proposed by which to figure out the internal characteristics of the deflector jet valve. | Hao Yan Yukai Ren Lei Yao Lijing Dong | 2019 | Chinese Journal of Mechanical Engineering2019,32,2: | 5 |
| 6 | Insight into vitronectin structural evolution on material surface chemistries: The mediation for cell adhesion显示文摘Biomaterial surface chemistry engenders profound consequences on cell adhesion and the ultimate tissue response by adsorbing proteins from extracellular matrix,where vitronectin(Vn)is involved as one of the crucial mediator proteins.Deciphering the adsorption behaviors of Vn in molecular scale provides a useful account of how to design biomaterial surfaces.But the details of structural dynamics and consequential biological effect remain elusive.Herein,both experimental and computational approaches were applied to delineate the conformational and orientational evolution of Vn during adsorption onto self-assembled monolayers(SAMs)terminating with-COOH,-NH2,-CH3 and-OH.To unravel the interplay between cell binding and the charge and wettability of material surface,somatomedin-B(SMB)domain of Vn holding the RGD cell-binding motif was employed in molecular dynamics(MD)simulations,with orientation initialized by Monte Carlo(MC)method.Experimental evidences including protein adsorption,cell adhesion and integrin gene expressions were thoroughly investigated.The adsorption of Vn on different surface chemistries showed very complex profiles.Cell adhesion was enabled on all Vn-adsorbed surfaces but with distinct mechanisms mostly determined by conformational change induced reorientation.Higher amount of Vn was observed on negatively charged surface(COOH)and hydrophobic surface(CH3).However,advantageous orientations defined by RGD loop conditions were only obtained on the charged surfaces(COOH and NH2).Specifically,COOH surface straightened up the Vn molecules and accumulated them into a higher density,whereas CH3 surface squashed Vn and stacked them into higher density multilayer by tracking adsorption but with the RGD loops restrained.These findings may have a broad implication on the understanding of Vn functionality and would help develop new strategies for designing advanced biomaterials. | Tianjie Li Lijing Hao Jiangyu Li Chang Du Yingjun Wang | 2020 | Bioactive Materials2020,5,4: | 4 |
| 7 | Cellulose nanofiber separator for suppressing shuttle effect and Li dendrite formation in lithium-sulfur batteries显示文摘Lithium-sulfur battery(LSB) has high energy density but is limited by the polysulfides shuttle and dendrite growth during cycling. Herein, a free-standing cellulose nanofiber(CNF) separator is designed and fabricated in isopropanol/water suspension through vacuum filtration progress. CNFs with abundant polar oxygen-containing functional groups can chemically immobilize the polysulfides, and suppress the formation of the dendrites by controlling the surface morphology of the SEI on lithium metal in LSB. The isopropanol content in a suspension can fine-tune the pore structure of the membrane to achieve optimal electrochemical performance. The prepared separator displays integrated advantages of an ultrathin thickness(19 μm), lightweight(0.87 mg cm^(-2)), extremely high porosity(98.05%), and decent electrolyte affinity. As a result, the discharge capacity of the LSB with CNF separator at the first and 100 th cycle is 1.4 and 1.3 times that of PP separator, respectively. Our research provides an environmentalfriendly and facile strategy for the preparation of multifunctional separators for LSBs. | Jingxue Li Liqin Dai Zhefan Wang Hao Wang Lijing Xie Jingpeng Chen Chong Yan Hong Yuan Hongliang Wang Chengmeng Chen | 2022 | Journal of Energy Chemistry2022,31,4: | 4 |
| 8 | Mechanistic insights into the adsorption and bioactivity of fibronectin on surfaces with varying chemistries by a combination of experimental strategies and molecular simulations显示文摘Fibronectin(Fn)is significant to the performance of biomaterials,and the chemistry of biomaterial surface play important roles in Fn adsorption and subsequent cell behavior.However,the“molecular scale”mechanism is still unclear.Herein,we combined experimental strategies with molecular simulations to solve this problem.We prepared self-assembled monolayers with varying chemistries,i.e.,SAMs-CH3,SAMs-NH2,SAMs-COOH and SAMs-OH,and characterized Fn adsorption and cell behaviors on them.Next,Monte Carlo method and all-atom molecular dynamics simulations were employed to reveal the orientation/conformation of Fn on surfaces.We found that SAMs-CH3 strongly adsorbed Fn via hydrophobic interactions,but show poor bioactivity as the low exposure of RGD/PHSRN motifs and the deformation of Fn.SAMs-NH2 and SAMs-COOH could adsorb Fn efficiently via vdW interactions,electrostatic interactions,hydrogen bonds and salt bridges.Fn exhibited excellent bioactivity for cell adhesion,proliferation and osteogenic differentiation as high exposure of bioactive motifs on SAMs-NH2,or as the activation of other inferior cell-binding motifs on SAMs-COOH.SAMs-OH showed poor Fn adsorption as the water film.However,the adsorbed Fn displayed non-negligible bioactivity due to high exposure of PHSRN motif and large degree of protein flexibility.We believe that the revealed mechanism presents great potential to rationally design Fn-activating biomaterials. | Lijing Hao Tianjie Li Lin Wang Xuetao Shi Yan Fan Chang Du Yingjun Wang | 2021 | Bioactive Materials2021,6,10: | 3 |
| 9 | 3D-printed bioactive ceramic scaffolds with biomimetic micro/nano-HAp surfaces mediated cell fate and promoted bone augmentation of the bone-implant interface in vivo显示文摘Calcium phosphate bio-ceramics are osteo-conductive,but it remains a challenge to promote the induction of bone augmentation and capillary formation.The surface micro/nano-topography of materials can be recognized by cells and then the cell fate are mediated.Traditional regulation methods of carving surface structures on bio-ceramics employ mineral reagents and organic additives,which might introduce impurity phases and affect the biological results.In a previous study,a facile and novel method was utilized with ultrapure water as the unique reagent for hydrothermal treatment,and a uniform hydroxyapatite(HAp)surface layer was constructed on composite ceramics(β-TCP/CaSiO_(3))in situ.Further combined with 3D printing technology,biomimetic hierarchical structure scaffolds were fabricated with interconnected porous composite ceramic scaffolds as the architecture and micro/nano-rod hybrid HAp as the surface layer.The obtained HAp surface layer favoured cell adhesion,alleviated the cytotoxicity of precursor scaffolds,and upregulated the cellular differentiation of mBMSCs and gene expression of HUVECs in vitro.In vivo studies showed that capillary formation,bone augmentation and new bone matrix formation were upregulated after the HAp surface layer was obtained,and the results confirmed that the fabricated biomimetic hierarchical structure scaffold could be an effective candidate for bone regeneration. | Xiao Liu Yali Miao Haifeng Liang Jingjing Diao Lijing Hao Zhifeng Shi Naru Zhao Yingjun Wang | 2022 | Bioactive Materials2022,7,6: | 2 |

| 12 | Adaptive sliding mode control of multi-agent relay tracking systems with disturbances显示文摘This paper studies the switching topologies and tracking agent replacements for a class of nonlinear multi-agent systems with external disturbances.In particular,it is assumed that a number of monitoring agents are randomly deployed in a two-dimensional space.The agents are committed to tracking any intrusion targets in this area.When one of the following agents exits tracking for some reasons,the agent closer to the target joins the tracking team to ensure the number of tracking agents does not change.In order to achieve the successful tracking of the target,this paper designs a sliding mode controller for the relay multi-agent system with tracking agent replacements.Furthermore,an adaptive law is proposed to estimate the upper bound of disturbance in the relay tracking process.Next,the stability of the overall system will be analysed by applying the multiple Lyapunov function method based on the average dwell time.Finally,the effectiveness of the tracking strategy is verified by numerical simulations. | Deyin Yu Lijing Dong Hao Yan | 2021 | Journal of Control and Decision2021,8,2: | 1 |
| 13 | Scientific objectives of the Hot Universe Baryon Surveyor(HUBS) mission显示文摘The Hot Universe Baryon Surveyor(HUBS) is a proposed space-based X-ray telescope for detecting X-ray emissions from the hot gas content in our universe. With its unprecedented spatially-resolved high-resolution spectroscopy and large field of view,the HUBS mission will be uniquely qualified to measure the physical and chemical properties of the hot gas in the interstellar medium, the circumgalactic medium, the intergalactic medium, and the intracluster medium. These measurements will be valuable for two key scientific goals of HUBS, namely to unravel the AGN and stellar feedback physics that governs the formation and evolution of galaxies, and to probe the baryon budget and multi-phase states from galactic to cosmological scales. In addition to these two goals, the HUBS mission will also help us solve some problems in the fields of galaxy clusters, AGNs, difuse X-ray backgrounds, supernova remnants, and compact objects. This paper discusses the perspective of advancing these fields using the HUBS telescope. | Joel Bregman Renyue Cen Yang Chen Wei Cui Taotao Fang Fulai Guo Edmund Hodges-Kluck Rui Huang Luis C.Ho Li Ji Suoqing Ji Xi Kang Xiaoyu Lai Hui Li Jiangtao Li Miao Li Xiangdong Li Yuan Li Zhaosheng Li Guiyun Liang Helei Liu Wenhao Liu Fangjun Lu Junjie Mao Gabriele Ponti Zhijie Qu Chenxi Shan Lijing Shao Fangzheng Shi Xinwen Shu Lei Sun Mouyuan Sun Hao Tong Junfeng Wang Junxian Wang Q.Daniel Wang Song Wang Tinggui Wang Weiyang Wang Zhongxiang Wang Dandan Xu Haiguang Xu Heng Xu Renxin Xu Xiaojie Xu Yongquan Xue Hang Yang Feng Yuan Shuinai Zhang Yuning Zhang Zhongli Zhang Yuanyuan Zhao Enping Zhou Ping Zhou | 2023 | Science China(Physics,Mechanics & Astronomy)2023,66,9: | 1 |

| 20 | Transcriptional Profile Alteration of Peripheral Blood in Chronic Hypoxia显示文摘Objective Many physiological and pathological conditions,including cyanotic congenital heart diseases(CCHD),are accompanied by chronic hypoxia,which might interfere with the transcription process.However,the transcriptome profile in peripheral blood under hypoxia is still unidentified.The present work aimed to explore the transcriptional profile alteration of peripheral blood in chronic hypoxia.Methods The present study used a chronic hypoxia rat model to simulate the hypoxic state of CCHD patients.Two groups of Sprague-Dawley rats(n=6 per group)were either exposed to hypoxia(10%O2)or normoxia(21%O2)for 3 weeks.Body weight was measured weekly.Peripheral blood was collected and total RNA was extracted for RNA-Seq at the end of the hypoxia treatment.After quality assessment,the library was sequenced by the Illumina Hiseq platform.The differentially expressed genes were screened(false discovery rate<0.05 and fold change>2).The functional annotation analysis and cluster analysis of differentially expressed genes were performed based on the adjusted P-value(padj<0.05).Results Compared with the control group,the body weight of the rats in the hypoxia group was significantly lowered(P<0.01).RNA-Seq results showed that the transcriptome patterns of the two groups had significant differences.In total,872 genes were identified as differentially expressed.Among all,803 genes were downregulated,while only 69 genes were up-regulated in the hypoxia group.The functional enrichment analysis of the 872 genes showed that multiple biological processes involved,such as porphyrin-containing compound metabolic process,hemoglobin complex and oxygen transporter activity.Conclusions Our study demonstrated the transcriptional profile alteration in peripheral blood of chronic hypoxia rat model.This study provided basic data and directions to further understand the physiological and pathological changes in patients with CCHD. | Tingting Wang Junyue Xing Lijing Zhang Hao Zhang | 2020 | Chinese Medical Sciences Journal2020,35,1: | 0 |
