| 2 | Performance and recent improvement in microbial fuel cells for simultaneous carbon and nitrogen removal: A review显示文摘Microbial fuel cells(MFCs) have become a promising technology for wastewater treatment accompanying electricity generation. Carbon and nitrogen removal can be achieved by utilizing the electron transfer between the anode and cathode in an MFC. However,large-scale power production and high removal efficiency must be achieved at a low cost to make MFCs practical and economically competitive in the future. This article reviews the principles, feasibility and bottlenecks of MFCs for simultaneous carbon and nitrogen removal, the recent advances and prospective strategies for performance improvement, as well as the involved microbes and electron transfer mechanisms. | Haishu Sun Shengjun Xu Guoqiang Zhuang Xuliang Zhuang | 2016 | Journal of Environmental Sciences2016，28，1： | 10 |
| 3 | Wheat genomic study for genetic improvement of traits in China显示文摘Bread wheat(Triticum aestivum L.)is a major crop that feeds 40%of the world’s population.Over the past several decades,advances in genomics have led to tremendous achievements in understanding the origin and domestication of wheat,and the genetic basis of agronomically important traits,which promote the breeding of elite varieties.In this review,we focus on progress that has been made in genomic research and genetic improvement of traits such as grain yield,end-use traits,flowering regulation,nutrient use efficiency,and biotic and abiotic stress responses,and various breeding strategies that contributed mainly by Chinese scientists.Functional genomic research in wheat is entering a new era with the availability of multiple reference wheat genome assemblies and the development of cutting-edge technologies such as precise genome editing tools,highthroughput phenotyping platforms,sequencing-based cloning strategies,high-efficiency genetic transformation systems,and speed-breeding facilities.These insights will further extend our understanding of the molecular mechanisms and regulatory networks underlying agronomic traits and facilitate the breeding process,ultimately contributing to more sustainable agriculture in China and throughout the world. | Jun Xiao Bao Liu Yingyin Yao Zifeng Guo Haiyan Jia Lingrang Kong Aimin Zhang Wujun Ma Zhongfu Ni Shengbao Xu Fei Lu Yuannian Jiao Wuyun Yang Xuelei Lin Silong Sun Zefu Lu Lifeng Gao Guangyao Zhao Shuanghe Cao Qian Chen Kunpu Zhang Mengcheng Wang Meng Wang Zhaorong Hu Weilong Guo Guoqiang Li Xin Ma Junming Li Fangpu Han Xiangdong Fu Zhengqiang Ma Daowen Wang Xueyong Zhang Hong-Qing Ling Guangmin Xia Yiping Tong Zhiyong Liu Zhonghu He Jizeng Jia Kang Chong | 2022 | Science China(Life Sciences)2022，65，9： | 9 |

| 5 | Targeting and exploitation of tumor-associated neutrophils to enhance immunotherapy and drug delivery for cancer treatment显示文摘Neutrophils,the most abundant leukocytes in human blood,are essential fighter immune cells against microbial infection.Based on the finding that neutrophils can either restrict or promote cancer progression,tumor-associated neutrophils(TAN)are classified into anti-tumor N1 and pro-tumor N2 subsets.One of the major mechanisms underlying the tumor-promoting function of N2-TANs is suppression of adaptive immune cells,in particular,cytotoxic T lymphocytes.Currently,no established methodologies are available that can unequivocally distinguish immunosuppressive TANs and granulocytic/polymorphonuclear myeloid-derived suppressor cells(G/PMN-MDSC).In view of the critical role of PMN-MDSCs in immune evasion and resistance to cancer immunotherapy,as established from data obtained with diverse cancer models,therapeutic strategies targeting these cells have been actively developed to enhance the efficacy of immunotherapy.Here,we have reviewed the available literature on strategies targeting PMN-MDSCs and summarized the findings into four categories:(1)depletion of existing PMN-MDSCs,(2)blockade of the development of PMNMDSCs,(3)blockade of PMN-MDSC recruitment,(4)inhibition of immunosuppressive function.Owing to their high mobility to inflamed organs and ability to trespass the blood-brain barrier,neutrophils are outstanding candidate carriers in nanoparticle-based therapies.Another attractive application of neutrophils in cancer therapy is the use of neutrophil membrane-derived nanovesicles as a surrogate of extracellular vesicles for more efficient and scalable drug delivery.In the second part of the review,we have highlighted recent advances in the field of neutrophil-based cancer drug delivery.Overall,we believe that neutrophil-based therapeutics are a rapidly growing area of cancer therapy with significant potential benefits. | Yuting Zhang Guoqiang Liu Miaomiao Sun Xin Lu | 2020 | Cancer Biology & Medicine2020，17，1： | 9 |

| 8 | Genomic insights into the fast growth of paulownias and the formation of Paulownia witches' broom显示文摘Paulownias are among the fastest growing trees in the world,but they often suffer tremendous loss of wood production due to infection by Paulownia witches'broom(PaWB)phytoplasmas.In this study,we have sequenced and assembled a high-quality nuclear genome of Paulownia fortunei,a commonly cultivated paulownia species.The assembled genome of P.fortunei is 511.6 Mb in size,with 93.2%of its sequences anchored to 20 pseudo-chromosomes,and it contains 31985 protein-coding genes.Phylogenomic analyses show that the family Paulowniaceae is sister to a clade composed of Phrymaceae and Orobanchaceae.Higher photosynthetic efficiency is achieved by integrating C3 photosynthesis and the crassulacean acid metabolism pathway,which may contribute to the extremely fast growth habit of paulownia trees.Comparative transcriptome analyses reveal modules related to cambial growth and development,photosynthesis,and defense responses.Additional genome sequencing of PaWB phytoplasma,combined with functional analyses,indicates that the effector PaWB-SAP54 interacts directly with Paulownia PfSPLa,which in turn causes the degradation of PfSPLa by the ubiquitin-mediated pathway and leads to the formation of witches'broom.Taken together,these results provide significant insights into the biology of paulownias and the regulatory mechanism for the formation of PaWB. | Yabing Cao Guiling Sun Xiaoqiao Zhai Pingluo Xu Liming Ma Minjie Deng Zhenli Zhao Haibo Yang Yanpeng Dong Zhonghai Shang Yujie Lv Lijun Yan Haifang Liu Xibing Cao Bingbing Li Zhe Wang Xiaogai Zhao Haiyan Yu Fan Wang Wen Ma Jinling Huang Guoqiang Fan | 2021 | Molecular Plant2021，14，10： | 7 |
| 9 | Room temperature ferromagnetism in ultra-thin van der Waals crystals of 1T-CrTe2显示文摘Although many emerging new phenomena have been unraveled in two dimensional(2D)materials with long-range spin orderings,the usually low critical temperature in van der Waals(vdW)magnetic material has thus far hindered the related practical applications.Here,we show that ferromagnetism can hold above 300 K in a metallic phase of 1T-CrTe2 down to the ultra-thin limit.It thus makes CrTe2 so far the only known exfoliated ultra-thin vdW magnets with intrinsic long-range magnetic ordering above room temperature.An in-plane room-temperature negative anisotropic magnetoresistance(AMR)was obtained in ultra-thin CrTe2 devices,with a sign change in the AMR at lower temperature,with−0.6%and+5%at 300 and 10 K,respectively.Our findings provide insights into magnetism in ultra-thin CrTe2,expanding the vdW crystals toolbox for future room-temperature spintronic applications. | Xingdan Sun Wanying Li Xiao Wang Qi Sui Tongyao Zhang Zhi Wang Long Liu Da Li Shun Feng Siyu Zhong Hanwen Wang Vincent Bouchiat Manuel Nunez Regueiro Nicolas Rougemaille Johann Coraux Anike Purbawati Abdellali Hadj-Azzem Zhenhua Wang Baojuan Dong Xing Wu Teng Yang Guoqiang Yu Bingwu Wang Zheng Han Xiufeng Han Zhidong Zhang | 2020 | Nano Research2020，13，12： | 6 |
| 10 | Numerical Simulation of Response of SRC Columns Subjected to Blast Loading显示文摘The dynamic characteristics and failure modes of steel reinforced concrete (SRC) columns subjected to blast loading are complicated because of the transient stress wave in the SRC columns and the interaction between steel and concrete. This paper presents a numerical simulation of the response of SRC columns subjected to blast loading using hydrocode LS-DYNA. In the numerical model, a sophisticate concrete material model (the Concrete Damage Model) is employed with consideration of the strain rate effect and the damage accumulation. An erosion technique is adopted to model the spalling process of concrete. The possible failure modes of SRC columns are evaluated. It is observed that the failure of SRC columns subjected to blast load can generally be classified into three modes, namely, a direct failure in concrete body due to the stress wave, a transverse shear failure near the support sections due to the high shear force, and a flexural failure pertaining to large local and global deformation of the reinforcing steel. | SUN Jianyun LI Guoqiang LU Yong | 2006 | Transactions of Tianjin University2006，12，B09： | 6 |
| 11 | Fenton-like degradation of Methylene Blue using paper mill sludge-derived magnetically separable heterogeneous catalyst:Characterization and mechanism显示文摘For the paper industry, the disposal and management of the yielded sludge are a considerable challenge. In our work, the paper mill sludge-derived magnetically separable heterogeneous catalyst(PMS-Fe-380) was prepared easily through a facile synthesis method. The morphology and structure of PMS-Fe-380 were fully characterized by means of X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy, and Brunauer–Emmet–Teller analysis. The catalytic activity of PMS-Fe-380 was evaluated by degradation of Methylene Blue(MB). The reusability and stability of PMS-Fe-380 were evaluated in five repeated runs, which suggested that PMS-Fe-380 manifested excellent stability of catalytic activity. Moreover,leaching tests indicated that the leached iron is negligible(<0.5 mg/L). This study provides an alternative environmentally friendly reuse method for paper mill sludge and a novel catalyst PMS-Fe-380 that can be considered as a promising heterogeneous Fenton-like catalyst. | Guoqiang Zhou Ziwen Chen Fei Fang Yuefeng He Haili Sun Huixiang Shi | 2015 | Journal of Environmental Sciences2015，27，9： | 6 |
| 12 | Chance-constrained Coordinated Optimization for Urban Electricity and Heat Networks显示文摘Urban electricity and heat networks(UEHN)consist of the coupling and interactions between electric power systems and district heating systems,in which the geographical and functional features of integrated energy systems are demonstrated.UEHN have been expected to provide an effective way to accommodate the intermittent and unpredictable renewable energy sources,in which the application of stochastic optimization approaches to UEHN analysis is highly desired.In this paper,we propose a chance-constrained coordinated optimization approach for UEHN considering the uncertainties in electricity loads,heat loads,and photovoltaic outputs,as well as the correlations between these uncertain sources.A solution strategy,which combines the Latin Hypercube Sampling Monte Carlo Simulation(LHSMCS)approach and a heuristic algorithm,is specifically designed to deal with the proposed chance-constrained coordinated optimization.Finally,test results on an UEHN comprised of a modified IEEE 33-bus system and a 32-node district heating system at Barry Island have verified the feasibility and effectiveness of the proposed framework. | Zhinong Wei Juan Sun Zhoujun Ma Guoqiang Sun Haixiang Zang Sheng Chen Side Zhang Kwok W.Cheung | 2018 | CSEE Journal of Power and Energy Systems2018，4，4： | 6 |

| 14 | Genome wide abnormal DNA methylome of human blastocyst in assisted reproductive technology显示文摘Proper reprogramming of parental DNA methylomes is essential for mammalian embryonic development.However,it is unknown whether abnormal methylome reprogramming occurs and is associated with the failure of embryonic development.Here we analyzed the DNA methylomes of 57 blastocysts and 29 trophectoderm samples with different morphological grades during assisted reproductive technology(ART) practices.Our data reveal that the global methylation levels of high-quality blastocysts are similar(0.30 ± 0.02,mean ± SD).while the methylation levels of low-quality blastocysts are divergent and away from those of high-quality blastocysts.The proportion of blastocysts with a methylation level falling within the range of 0.30 ± 0.02 in different grades correlates with the live birth rate for that grade.Moreover,abnormal methylated regions are associated with the failure of embryonic development.Furthermore,we can use the methylation data of cells biopsied from trophectoderm to predict the blastocyst methylation level as well as to detect the aneuploidy of the blastocysts.Our data indicate that global abnormal methylome reprogramming often occurs in human embryos,and suggest that DNA methylome is a potential biomarker in blastocyst selection in ART. | Guoqiang Li Yang Yu Yong Fan Congru Li Xiaocui Xu Jialei Duan Rong Li Xiangjin Kang Xin Ma Xuepeng Chen Yuwen Ke Jie Yan Ying Lian Ping Liu Yue Zhao Hongcui Zhao Yaoyong Chen Xiaofang Sun Jianqiao Liu Jie Qiao Jiang Liu | 2017 | Journal of Genetics and Genomics2017，44，10： | 5 |
| 15 | Echo-to-reverberation enhancement based on decomposition of time reversal operator with forward and backward reverberation nulling constrains显示文摘Combined the decomposition of time reversal operator and the time reversal re- verberation nulling,a new time reversal processing approach for echo-to-reverberation ratio enhancement is proposed.In this method,a 2-dimensional signal subspace for the range of the target and two bottom focusing weight vectors for the ranges near the target are obtained by the decomposition of time reversal operator.From the signal subspace and focusing weight vectors,a constrained optimal excitation weight vector of source receiver array can be deduced to null the acoustic energy on the corresponding bottom and maximize the energy at the tar- get.This method remedies the shortages of conventional time reversal processing,time reversal reverberation nulling and time reversal selective focusing method.It focuses sound energy at the target and nulls the energy at the bottom near the target range simultaneously,therefore enhancing the echo-to-reverberation ratio without probe source and prior-knowledge of the rel- ative scattering intensity of target and bottom.Numerical simulations in typical shallow water environments showed the effectiveness of the proposed method and its improved performance for echo-reverberation enhancement than conventional time reversal processing. | GUO Guoqiang YANG Yixin SUN Chao | 2009 | Chinese Journal of Acoustics2009，28，1： | 4 |
| 16 | The m6A methylation regulates gonadal sex differentiation in chicken embryo显示文摘Background:As a ubiquitous reversible epigenetic RNA modification,N6-methyladenosine(m6A)plays crucial regulatory roles in multiple biological pathways.However,its functional mechanisms in sex determination and differentiation during gonadal development of chicken embryos are not clear.Therefore,we established a transcriptome-wide m6A map in the female and male chicken left gonads of embryonic day 7(E7)by methylated RNA immunoprecipitation sequencing(MeRIP-seq)to offer insight into the landscape of m6A methylation and investigate the post-transcriptional modification underlying gonadal differentiation.Results:The chicken embryonic gonadal transcriptome was extensively methylated.We found 15,191 and 16,111 m6A peaks in the female and male left gonads,respectively,which were mainly enriched in the coding sequence(CDS)and stop codon.Among these m6A peaks,we identified that 1013 and 751 were hypermethylated in females and males,respectively.These differential peaks covered 281 and 327 genes,such as BMP2,SMAD2,SOX9 and CYP19A1,which were primarily associated with development,morphogenesis and sex differentiation by functional enrichment.Further analysis revealed that the m6A methylation level was positively correlated with gene expression abundance.Furthermore,we found that YTHDC2 could regulate the expression of sex-related genes,especially HEMGN and SOX9,in male mesonephros/gonad mingle cells,which was verified by in vitro experiments,suggesting a regulatory role of m6A methylation in chicken gonad differentiation.Conclusions:This work provided a comprehensive m6A methylation profile of chicken embryonic gonads and revealed YTHDC2 as a key regulator responsible for sex differentiation.Our results contribute to a better understanding of epigenetic factors involved in chicken sex determination and differentiation and to promoting the future development of sex manipulation in poultry industry. | Jianbo Li Xiuan Zhang Xiqiong Wang Congjiao Sun Jiangxia Zheng Junying Li Guoqiang Yi Ning Yang | 2022 | Journal of Animal Science and Biotechnology2022，13，6： | 4 |
| 17 | A cross-linked polyacrylamide electrolyte with high ionic conductivity for compressible supercapacitors with wide temperature tolerance显示文摘The development of compressible supercapacitors (SCs) that is tolerant to wide temperature range has been severely hindered due to the poor ionic conductivity and absence of extra functions in conventional polymer electrolytes.Herein,a highly conductive and compressible hydrogel polyelectrolyte has been prepared from polyacrylamide cross-linked by methacrylated graphene oxide (MGO-PAM) and the polyelectrolyte can maintain its excellent elasticity at-30 ℃ as well as its original shape at 100 ℃.As a result,the SC based on the MGO-PAM polyelectrolyte outperformed those fabricated with the conventional poly(vinyl alcohol)(PVA)/H2SO4 electrolyte over a wide temperature window between-30 and 100 ℃.Meanwhile,the device shows an excellent cycling stability (capacitance retention of 93.3% after 8,000 cycles at-30 ℃ and 76.5 % after 4,000 cycles under 100 ℃) and a reversible compressibility (a high capacitance retention of 94.1% under 80% compression).Therefore,the MGO-PAM polyelectrolyte enables the fabrication of compressible SCs with a wide operating temperature,rendering new insights for developing next-generation robust and multifunctional energy-storage devices. | Xuting Jin Guoqiang Sun Guofeng Zhang Hongsheng Yang Yukun Xiao Jian Gao Zhipan Zhang Liangti Qu | 2019 | Nano Research2019，12，5： | 4 |

| 20 | Effect of Friction Reclaimed Materials of Waste Brake-shoe on Basic Performance of Mortar显示文摘Discarded train brake shoes mainly consist of steel-backed friction material. To be better reutilized, its essential features and its interaction in cement-based material need to be studied. Consequently, particle size analysis, SEM, IR and TGA were used to investigate two types of waste brake shoes, i e, mechanical grinding friction reclaimed material of waste brake-shoe(G-FRMWBS) and pyrolysis-friction reclaimed materials of waste brake-shoe(P-FRMWBS). The latter exhibited less organic content, larger range of particle size distribution and smaller medium particle diameter. Both types contained inorganic particles of spherical and irregular shapes, striped with steel fiber. Upon isometric substituting fine aggregates, G-FRMWBS lifted the strength of mortar effectively that was increased by 16.6% and 17.5% when the replacing rate was 5%; the value went up to 19.2% and 19.2% when the replacing rate was 10%. Moreover, inclusion of FRMWBS enhanced the chloride penetration resistance, and optimized the pore characteristic and ITZ(interfacial transition zone) as well. | 王彩辉 HUANG Dongjie FU Hua WU Hongya QIN Guoqiang SUN Guowen GUO Na | 2017 | Journal of Wuhan University of Technology(Materials Science)2017，32，3： | 3 |
