| 1 | Boron modulating electronic structure of FeN4C to initiate high-efficiency oxygen reduction reaction and high-performance zinc-air battery显示文摘The biggest challenge is to develop a low cost and readily available catalyst to replace expensive commercial Pt/C for efficient electrochemical oxygen reduction reaction(ORR).In this research,closo-[B_(12)H_(12)]^(2−)and 1,10-phenanthroline-iron complexes were introduced into the porous metal-organic framework by impregnation method,and further annealing treatment achieved the successful anchoring of single-atom-Fe in B-doped CN Matrix(FeN4CB).The ORR activity of FeN4CB is comparable to the widely used commercial 20 wt%Pt/C.Where the half-wave potential(E_(1/2))in alkaline medium up to 0.84 V,and even in the face of challenging ORR in acidic medium,the E_(1/2)of ORR driven by FeN4CB is still as high as 0.81 V.When FeN4CB was used as air cathode,the open circuit voltage of Zn-air battery reaches 1.435 V,and the power density and specific capacity are as high as 177 mW cm^(−2)and 800 mAh g_(Zn)^(−1)(theoretical value:820 mAh g_(Zn)^(−1)),respectively.The dazzling point of FeN4CB also appears in the high ORR stability,whether in alkaline or acidic media,E_(1/2)and limiting current density are still close to the initial value after 5000 times cycles.After continuously running the charge-discharge test for 220 h,the charge voltage and discharge voltage of the rechargeable zinc-air battery with FeN4CB as the air cathode maintained the initial state.Density functional theory calculations reveals that introducing B atom to Fe–N4–C can adjust the electronic structure to easily break O=O bond and significantly reduce the energy barrier of the rate-determining step resulting in an improved ORR activity. | Xue Zhao Xue Li Zenghui Bi Yuwen Wang Haibo Zhang Xiaohai Zhou Quan Wang Yingtang Zhou Huaisheng Wang Guangzhi Hu | 2022 | Journal of Energy Chemistry2022,31,3: | 6 |
| 2 | Surveying brain tumor heterogeneity by single-cell RNA-sequencing of multi-sector biopsies显示文摘Brain tumors are among the most challenging human tumors for which the mechanisms driving progression and heterogeneity remain poorly understood.We combined single-cell RNA-seq with multi-sector biopsies to sample and analyze single-cell expression profiles of gliomas from 13 Chinese patients.After classifying individual cells;we generated a spatial and temporal landscape of glioma that revealed the patterns of invasion between the different sub-regions of gliomas.We also used single-cell inferred copy number variations and pseudotime trajectories to inform on the crucial branches that dominate tumor progression.The dynamic cell components of the multi-region biopsy analysis allowed us to spatially deconvolute with unprecedented accuracy the transcriptomic features of the core and those of the periphery of glioma at single-cell level.Through this rich and geographically detailed dataset,we were also able to characterize and construct the chemokine and chemokine receptor interactions that exist among different tumor and non-tumor cells.This study provides the first spatial-level analysis of the cellular states that characterize human gliomas.It also presents an initial molecular map of the cross-talks between glioma cells and the surrounding microenvironment with single-cell resolution. | Kai Yu Yuqiong Hu Fan Wu Qiufang Guo Zenghui Qian Waner Hu Jing Chen Kuanyu Wang Xiaoying Fan Xinglong Wu John EJ Rasko Xiaolong Fan Antonio lavarone Tao Jiang Fuchou Tang Xiao-Dong Su | 2020 | National Science Review2020,7,8: | 4 |
| 3 | Analysis of floral scent emitted from Syringa plants显示文摘Syringa is an important aromatic woody angiosperm that is widely planted in gardens. Its dry flowers are traditionally used to manufacture infusions and spices in China. In this study, the floral volatiles emitted from nine different Syringa species and varieties, viz.S. chinensis, S. protolaciniata, S. oblata, S. oblata var.giraldii, S. oblata var. plena, S. vulgaris ‘Mrs Harry Bickle', S. vulgaris ‘Bright Centennial', S. vulgaris ‘White Spires', and S. vulgaris ‘President Lincoln' were collected by the dynamic headspace technique, and then identified by automated thermal desorption–gas chromatography/mass spectrometry. There were significant differences incomponents and corresponding contents of floral scent emitted from the nine Syringa species and varieties.Among the detected components, b-ocimene exhibited the highest content, accounting for more than 70 % of the floral scent of S. protolaciniata, S. oblata var. giraldii, and S. vulgaris ‘Bright Centennial'. A significant daytime variation of floral scent emitted from S. pekinensis was recorded, especially for benzaldehyde, whose content first increased and then decreased. We studied the scent emitted from the in vitro flowers of S. vulgaris ‘Pres Lincoln'during the process of natural drying. Alcohol compounds were released in the greatest content, and the content of 2-ethyl-1-hexanol accounted for about 40 % of the total release amount. The results described the emission pattern and mechanisms of floral scent in Syringa. | Xiaoxia Yang Jing Zhao Jian Zheng Pingsheng Leng Xiaolong Li Zenghui Hu Jianbin Liu Xin Meng | 2016 | Journal of Forestry Research2016,27,2: | 3 |

| 5 | Gene cloning and expression analysis of limonene synthase in Syringa oblata and S.oblata var.alba显示文摘Syringa species are important ornamentals with strong floral scent,of which monoterpenes are the main component.In this study,a new monoterpene synthase gene,named SoLIM,was collected from the flowers of Syringa oblata and S.oblata var.alba using a homologous cloning method.The full-length cDNA of SoLIM was1746 bp and encoded 581 amino acids.Sequence analysis showed that SoLIM contained the DDxxD and RRx8 W motifs,which are two typical conserved monoterpene synthase motifs,and was thus classified as belonging to the Tpsb subfamily.Using quantitative reverse-transcription PCR,SoLIM was significantly expressed in the petals and pistils of S.oblata and S.oblata var.alba,respectively.SoLIM expression peaked earlier than the D-limonene emissions in the diurnal experiments,but occurred later when D-limonene had peaked during the flowering phase,indicating that differences in SoLIM gene expression and D-limonene emissions existed.The synthesis of floral scent is thus associated with diverse regulatory mechanisms that require further investigation. | Zifei Yan Ying Qin Jian Zheng Pingsheng Leng Zenghui Hu | 2019 | Journal of Forestry Research2019,30,4: | 1 |

| 7 | Cloning and Expression Analysis of Allene Oxide Synthase Gene Ls AOS in Lilium‘Siberia'显示文摘[Objectives] Allene oxide synthase( AOS),the first specific enzyme in the biosynthetic pathway of jasmonate( JA),has an important role in regulating JA accumulation in plants. This study was conducted to amplify full-length AOS gene from Lilium‘Siberia'( LsAOS) and to explore the spatiotemporal expression of this gene. [Methods]LsAOS was cloned by rapid amplification of c DNA ends( RACE) and analyzed bioinformatically. LsAOS expression level in nine organs/tissues and at four flowering stages was determined by quantitative PCR( q-PCR). [Results] LsAOS gene has an open reading frame of 1 542 bp,encoding a protein of 514 amino acids. The LsAOS protein sequence was more homologous with the AOS protein of Musa acuminata Colla than that in any other plant species.The LsAOS expression reached the maximum level at bud stage,and then gradually decreased over time during the flowering period. The LsAOS expression level in leaves was the highest,followed by in inner petals,roots,stems,etc. [Conclusions]JA participates in the whole process of plant development,and is closely related to stress resistance and secondary metabolism. AOS is one of the key genes in JA pathway and plays an important role in regulating the biosynthesis of JA. | qi wu pingsheng leng zenghui hu | 2018 | Agricultural Biotechnology2018,7,2: | 1 |

| 11 | Stability analysis for semi-Markovian switched stochastic systems with asynchronously impulsive jumps显示文摘The almost surely(a.s.)exponential stability is studied for semi-Markovian switched stochastic systems with randomly impulsive jumps.We start from the case that switches and impulses occur synchronously,in which the impulsive switching signal is a semi-Markovian process.For the case that switches and impulses occur asynchronously,the impulsive arrival time sequence and the types of jump maps are driven by a renewal process and a Markov chain,respectively.By applying the multiple Lyapunov function approach,sufficient conditions of exponential stability a.s.are obtained based upon the ergodic property of semi-Markovian process.The validity of the proposed theoretical results is demonstrated by a numerical example. | Xiaowu MU Zenghui HU | 2021 | Science China(Information Sciences)2021,64,1: | 0 |

| 13 | Monitoring and evaluation of disaster risk caused by linkage failure and instability of residual coal pillar and rock strata in multi-coal seam mining显示文摘Comprehensive research methods such as literature research,theoretical analysis,numerical simulations and field monitoring have been used to analyze the disasters and characteristics caused by the linkage failure and instability of the residual coal pillars-rock strata in multi-seam mining.The effective monitoring area and monitoring design method of linkage instability of residual coal pillar-rock strata in multi-seam mining have been identified.The evaluation index and the risk assessment method of disaster risk have been established and the project cases have been applied and validated.The results show that:①The coal pillar will not only cause disaster in singleseam mining,but also more easily cause disaster in multi-seam mining.The instability of coal pillars can cause not only dynamical disasters such as rock falls and mine earthquakes,but also cause surface subsidence and other disasters.②When monitoring the linkage instability of residual coal pillar-rock strata,it is not only necessary to consider the monitoring of the apply load body(key block),the transition body(residual coal pillar)and the carrier body(interlayer rock and working face),but also to strengthen the monitoring of the fracture development height(linkage body).③According to the principles of objectivity,easy access and quantification,combined with investigation,analysis,and production and geological characteristics of this mining area,the main evaluation indexes of the degree of disaster caused by linkage instability of residual coal pillar-rock strata are determined as:microseismic energy,residual coal pillar damage degree,fracture development height.And the evaluation index classification table was also given.④According to the measured value of the evaluation index,the fuzzy comprehensive evaluation method was used to calculate the disaster risk degree in the studied mine belongs to class III,that is,medium risk level.The corresponding pressure relief technology was adopted on site,which achieved a good control effect,and also verified the accuracy and effectiveness of the risk evaluation results. | Qing Ma Xiaoli Liu Yunliang Tan Yurui Wang Ruosong Wang Enzhi Wang Xuesheng Liu Zenghui Zhao Darui Ren Weiqiang Xie Ruipeng Qian Nan Hu | 2023 | Geohazard Mechanics2023,1,4: | 0 |
