| 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 |

| 3 | Spatial variations of macrozoobenthos and sediment nutrients in Lake Yangcheng: Emphasis on effect of pen culture of Chinese mitten crab显示文摘We determined the effect of Chinese mitten crab(CMC) pen culture on the quantified spatial distribution of the macrozoobenthic community and sediment nutrients in Lake Yangcheng.Redundancy analysis indicated that water temperature, macrophyte occurrence, sediment type, and crab culture were the main environmental factors that influence the spatiotemporal macrozoobenthic distribution. Macrozoobenthic assemblages in the lake were characterized by eutrophic indicator species. In the most polluted estuaries, the abundance and diversity indices of the whole community and abundance of chironomids and oligochaetes were significantly depressed, and sediment carbon(C) and phosphorus(P) were significantly enhanced compared with those in the western, middle(MB), and eastern basin(EB). Crab culture in this lake had significant effects on the species composition of the macrozoobenthic community in one of three CMC culture pens(CP), and generally depressed the abundance of most chironomid and oligochaete species. Significantly increased diversity, evenness, sediment carbon and nitrogen content, and sediment C:P ratio in the CP were found compared with those in the three basins.However, no conspicuous difference in sediment P content between the CP and the two basins of MB and EB was detected. Our results showed that the enhanced diversity and evenness of macrozoobenthos might be associated with the joint effect of macrophyte planting and crab predation, and macrophyte planting may modify the effects of CMC culture by leading to disproportional accumulation of C and N in the sediment relative to P in the CP of the lake. | Liping Chen Ying Zhang Qigen Liu Zhongjun Hu Yuejuan Sun Ziran Peng Lijing Chen | 2015 | Journal of Environmental Sciences2015,27,11: | 15 |
| 4 | Lopingian mixed floras from Linxi Formation in Soron area,Inner Mongolia显示文摘A lot of well-preserved plants from the Linxi Formation are collected in the Soron area,Inner Mongolia,consisting of 34 species of 16 genera. They are Late Permian in age. The flora is characterized by a lot of Angaran plants,such as Paracalamites,Comia,Rhachiphyllum,Iniopteris,Rufloria,etc. Some Cathaysian elements,such as Lobatannularia lingulata,L. multifolia,Fascipteris Cathaysiantus,F. densata,Taeniopteris szei,Cladophlebis liulinensis and C. permica,are also mixed within the present flora. This indicates that the Soron of Inner Mongolia was located in the sector between the Angaran and Cathysian floristic provinces in Lopingian. It is beneficial for depicting the location and the evolution of the Solenker--Xar Moron suture zone in the phytogeographic view. The transmigration of tropical and subtropical Cathaysian plants to the north indicates that the Paleoasian Ocean was closed during the late Permian along the suture zone. | ZHANG Dejun SUN Yuewu DING Haisheng YANG Zhenyuan TANG Lijing | 2014 | Global Geology2014,17,2: | 10 |
| 5 | Selective laser melting of Al–8.5Fe–1.3V–1.7Si alloy: Investigation on the resultant microstructure and hardness显示文摘This article presents the microstructure and hardness variation of an Al–8.5Fe–1.3V–1.7Si(wt%, FVS0812) alloy after selective laser melting(SLM) modification. Three zones were distinguished across the melting pool of the SLM-processed FVS0812 alloy: the laser melted zone(LMZ), the melting pool border, and the heat affected zone(HAZ) in the previously deposited area around the melting pool. Inside the LMZ, either an extremely fine cellular-dendritic structure or a mixture zone of the a-Al matrix and nanoscale Al_(12)(Fe,V)_3Si particles appeared. With a decreased laser beam scanning speed, the cellular-dendritic structure zone within the LMZ shrank significantly while the mixture zone expanded. The a-Al and Al_(12)(Fe,V)_3Si mixture zone was also observed in the HAZ, but another phase, submicron h-Al_(13)Fe_4 particles with rectangular or hexagonal shapes,formed along the melting pool border. Microhardness tests indicated that the hardness of the SLM-processed FVS0812 samples far exceeded that of the as-cast FVS0812 alloy. | Zheng Lijing Liu Yingying Sun Shaobo Zhang Hu | 2015 | Chinese Journal of Aeronautics2015,28,2: | 9 |
| 6 | 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 |
| 7 | Adsorption removal of o-nitrophenol and p-nitrophenol from wastewater by metal–organic framework Cr-BDC显示文摘In the present paper, a metal–organic framework Cr-BDC was prepared and used as adsorbent for adsorption of o-nitrophenol(ONP) and p-nitrophenol(PNP) from aqueous solutions. Cr-BDC was characterized by scanning electron microscopy, transmission electron microscope, X-ray diffraction and BET methods. The results indicate that Cr-BDC gets a very large specific surface area of 4128 m^2·g^(-1)and pore sizes are concentrated in 1 nm, which is a benefit for using for wastewater treatment. The influences of the adsorption conditions, such as temperature,solution concentration, adsorption time and reusability on adsorption performance were investigated. Cr-BDC exhibited an encouraging uptake capacity of 310.0 mg·g^(-1)for ONP, and adsorption capacity of Cr-BDC for ONP is significantly higher than that for PNP under suitable adsorption conditions. The characterizations of adsorption process were examined with the Lagergren pseudo-first-order, the pseudo-second-order kinetic model, and the intra-particular diffusion model. Kinetics experiments indicated that the pseudo-second-order model displayed the best correlation with adsorption kinetics data. Furthermore, our adsorption equilibrium data could be better described by the Freundlich equation. The results indicate that the as-prepared Cr-BDC is promising for use as an effective and economical adsorbent for ONP removal. | Jianhua Chen Xue Sun Lijing Lin Xinfei Dong Yasan He | 2017 | Chinese Journal of Chemical Engineering2017,25,6: | 6 |
| 8 | Effect of emodin on Aquaporin 5 expression in rats with sepsis-induced acute lung injury显示文摘OBJECTIVE: To investigate the effects of emodin on aquaporin 5(AQP5) expression in rats with sepsis-induced acute lung injury.METHODS: We divided 60 adult male Sprague-Dawley rats, weighing 200-230 g, into four groups: control, sham surgery, model and emodin groups(n = 15 for each). We created a sepsis model with cecal ligation and puncture; the sham surgery group had their cecums replaced after exposure outside the abdominal cavity. Each group was further divided into three subgroups(n = 5 for each)and expressions of AQP5 m RNA and proteins in lung tissue were measured by real-time fluorescence polymerase chain reaction and western blot at 6, 12 and 24 h after surgery.RESULTS: AQP5 expression did not change over time in the control group and sham surgery group,but decreased over time in the model group. The lowest expression was found in 12-h subgroup,which significantly differed from the 6-h subgroup(P < 0.01). Compared with the model group, AQP5 expression in the emodin group was significantly higher in all the subgroups(all P <0.01). Expressions in the 12-h subgroup were the highest, and significantly differed from the other subgroups. We found that lung tissue damage,such as pulmonary edema, alveolar damage and the exudation of red blood cells in pulmonary interstitium and alveolar, was significantly milder in the emodin group under light microscope than the model group.CONCLUSION: AQP5 expression was significantly down-regulated in rats with sepsis-induced acute lung injury induced by cecal ligation and puncture.Early prophylactic use of emodin can significantly enhance the AQP5 expression, thus effectively reducing the degree of pulmonary edema in septic rats. | Sun Yanni Sun Lijing Liu Shuqing Song Juan Cheng Jiejing Liu Jun | 2015 | Journal of Traditional Chinese Medicine2015,35,6: | 5 |
| 9 | Study on the ore-forming and ore-controlling structure of the Mujicun Cu (Mo) ore deposit, Hebei Province, China显示文摘The Mujicun Cu (Mo) ore deposit at Laiyuan, Hebei Province, is a currently proven large-sized Cu (Mo) polymetallic ore deposit and it is located in the second-ordered fault depression basin of the ditachment belt on the hanging-wall on the western side at the juncture of the Laiyuan dumbell-shaped complex in the northern part of the Fuping mantle-branch structure. Metallogenesis is controlled by diorite porphyrite in intrusive relation with the fault depression basin and other relevant fault structure systems and intenstive wall-rock alteration zones. This study, in conjunction with the most recent exploration data, analyzed the geological background of metallogenesis of this deposit, summaried the geological characteristics of typical ore deposits, determined the alteration zonation of the deposit, investigated regional metallogenesis and the genesis of typical ore deposits, discussed the regional ore-forming and ore-controlling structures, and generalized the regional ore-controlling model and metallogenic model of the deposit. It is considered that the Mujicun porphry Cu (Mo) deposit, the Tieling, Futuyu, Xiaoligou and other skarn-type Fe-Cu deposits and the He'ergou hydrothermal-type Pb-Zn-Ag deposit jointly constitute a three-in-one polymetallic orefield, with the characteristics of typical metallogenic series. | NIU Shuyin MA Guoxi CHEN Zhikuan WANG Baode CHEN Lijing SUN Aiqun MA Xiaofeng ZHANG Jianzhen MA Baojun CHEN Chao LU Hongpeng | 2012 | Chinese Journal Of Geochemistry2012,31,1: | 2 |
| 10 | Improving seeking precision by utilizing ghost imaging in a semi-active quadrant detection seeker显示文摘Conventional semi-active laser guidance takes advantage of the laser designator to illuminate the stable and uniform laser spot on target precisely.The seeker collects the reflected light by a quadrant detector and outputs the relative position information to guide the missile to the illuminating laser spot.However,the designation and guidance accuracy could be jeopardized by the randomly drifting of laser spot caused by the instability of designation platform and air turbulence.In this work,ghost imaging technique is adapted to a quadrant detector semi-active seeker by utilizing structured illumination on the target.With a series of structured illumination masks,the signals from the quadrant detector are multiplexed to perform calculation of the target relative position as well as image reconstruction of the illuminated area simultaneously.Automatic target recognition methods could be further applied to the reconstructed image to calculate the designating error and correct the guidance.The results of simulation and experiment demonstrate that the proposed method could improve the guidance accuracy in many circumstances which would lead to attacking deviation if conventional semi-active laser guidance is used. | Siyuan WANG Lijing LI Wen CHEN Mingjie SUN | 2021 | Chinese Journal of Aeronautics2021,34,12: | 1 |

| 14 | A high-resolution cell atlas of the domestic pig lung and an online platform for exploring lung single-cell data显示文摘The genetically engineered pig is regarded as an optimal source of organ transplantation for humans and an excellent model for human disease research,given its comparable physiology to human beings.A myriad of single-cell RNA sequencing(sc RNA-seq)data on humans has been reported,but such data on pigs are scarce.Here,we apply sc RNA-seq technology to study the cellular heterogeneity of 3-month-old pig lungs,generating the single-cell atlas of 13,580 cells covering 16 major cell types.Based on these data,we systematically characterize the similarities and differences in the cellular cross-talk and expression patterns of respiratory virus receptors in each cell type of pig lungs compared with human lungs.Furthermore,we analyze pig lung xenotransplantation barriers and reported the cell-type expression patterns of 10 genes associated with pig-to-human immunobiological incompatibility and coagulation dysregulation.We also investigate the conserved transcription factors(TFs)and their candidate target genes and constructed five conserved TF regulatory networks in the main cell types shared by pig and human lungs.Finally,we present a comprehensive and openly accessible online platform,Scdb Lung.Our sc RNA-seq atlas of the domestic pig lung and Scdb Lung database can guide pig lung research and clinical applicability. | Lijing Zhang Jiacheng Zhu Haoyu Wang Jun Xia Ping Liu Fang Chen Hui Jiang Qiuling Miao Weiying Wu Lingli Zhang Lihua Luo Xiaosen Jiang Yong Bai Chengcheng Sun Dongsheng Chen Xingliang Zhang | 2021 | Journal of Genetics and Genomics2021,48,5: | 1 |

| 19 | New loci for refractive errors and ocular biometric parameters in young Chinese Han adults显示文摘Myopia has become a major public health issue with an increasing prevalence.There are still individuals who experience similar environmental risk factors and,yet,remain non-myopic.Thus,there might be genetic factors protecting people from myopia.Considering the opposite ocular characteristics of primary angle closure glaucoma(PACG)to myopia and possible common pathway between them,we propose that certain risk genes for PACG might act as a protective factor for myopia.In this study,2,678 young adults were genotyped for 37 targeted single nucleotide polymorphisms.Compared with emmetropia,rs1401999(allele C:OR=0.795,P=0.03;genotype in dominant model:OR=0.759,P=0.02)and rs1258267(allele A:OR=0.824,P=0.03;genotype in dominant model:OR=0.603,P=0.01)were associated with low to moderate myopia and high myopia,respectively.Genotype under recessive model of rs11024102 was correlated with myopia(OR=1.456,P=0.01),low to moderate myopia(OR=1.443,P=0.02)and high myopia(OR=1.453,P=0.02).However,these associations did not survive Bonferroni correction.Moreover,rs1401999,rs1258267,and rs11024102 showed associations with certain ocular biometric parameters in different groups.Our study suggests that ABCC5,CHAT and PLEKHA7 might be associated with refractive errors by contributing to the regulation of ocular biometry,in terms of uncorrected results and their biological functions. | Yunyun Sun Zi-Bing Jin Shifei Wei Hongyan Jia Kai Cao Jianping Hu Caixia Lin Wenzai An Jiyuan Guo He LiJing Fu Shi-Ming Li Ningli Wang the Anyang University Students Eye Study Group the Anyang University Students Eye Study Group | 2022 | Science China(Life Sciences)2022,65,10: | 1 |
