| 1 | Multi-dimension apportionment of clean air “parade blue”phenomenon in Beijing显示文摘The mass concentration and major chemical components of fine particulate matter were measured before,during and after Beijing's massive parade commemorating 70th anniversary of the Chinese Victory in World War II on September 3,2015.Regional emission inventory,positive matrix factorization(PMF),observations from space and backward air mass trajectories were jointly applied to identify the major pollution sources and their temporal and spatial variations.The contributions of emissions variations and the meteorological conditions related to the'parade blue'phenomenon in Beijing and its surrounding areas were investigated in detail.The main cause of the decreased PM_(2.5)mass concentration was attributed to the absolute reduction in emissions of primary air pollutants.The chemical composition of PM_(2.5)varied significantly before,during and after the parade.Fugitive dust particles were well controlled,the secondary formation of PM_(2.5)was reduced along with the controlled gaseous precursors'emissions from vehicles and industrial sources during the temporary intensified control period.During the parade period,the SO_2and NO_2column concentrations in Beijing and the surrounding areas decreased sharply,indicating that the coordinated reduction in primary emissions from the surrounding areas of Beijing played an important role in lowering the ambient concentration of SO_2and NO_2and accordingly lowered PM_(2.5)and improved the regional air quality.A comparison of the temperature,humidity,and wind speed and direction during the same periods in 2014 and 2015 showed that the meteorological conditions positively influenced the achievement of'parade blue'. | Yifeng Xue Yong Wang Xuefeng Li Hezhong Tian Lei Nie Xiaoqing Wu Junrui Zhou Zhen Zhou | 2018 | Journal of Environmental Sciences2018，30，3： | 5 |
| 2 | PpERF3 positively regulates ABA biosynthesis by activating PpNCED2/3 transcription during fruit ripening in peach显示文摘The plant hormone ethylene regulates ripening in climacteric fruits.The phytohormone abscisic acid(ABA)affects ethylene biosynthesis,but whether ethylene influences ABA biosynthesis is unknown.To explore this possibility,we investigated the interactions between the ABA biosynthesis genes PpNCED2/3 and the ethylene response transcription factor PpERF3 in peach fruit.The ABA content increased during fruit maturation and reached a peak at stage S4 III.The increase was greatly inhibited by the ethylene inhibitor 1-MCP,which also suppressed PpERF3 expression.PpERF3 shared a similar expression profile with PpNCED2/3,encoding a rate-limiting enzyme involved in ABA biosynthesis,during fruit ripening.A yeast one-hybrid assay suggested that the nuclear-localized PpERF3 might bind to the promoters of PpNCED2/3.PpERF3 increased the expression of PpNCED2/3 as shown by dual-luciferase reporters,promoter-GUS assays and transient expression analyses in peach fruit.Collectively,these results suggest that ethylene promotes ABA biosynthesis through PpERF3’s regulation of the expression of ABA biosynthesis genes PpNCED2/3. | Xiaobei Wang Wenfang Zeng Yifeng Ding Yan Wang Liang Niu Jia-Long Yao Lei Pan Zhenhua Lu Guochao Cui Guohuai Li Zhiqiang Wang | 2019 | Horticulture Research2019，6，1： | 5 |
| 3 | N-doped ordered mesoporous carbon spheres derived by confined pyrolysis for high supercapacitor performance显示文摘Herein, we report a confined pyrolysis strategy to prepare mesoporous carbon nanospheres by which surface area of carbon spheres is increased, pore size is enlarged and effective N-doping is achieved. In this method, the mesoporous polymer sphere as carbon precursor and 2-methylimidazole as nitrogen precursor are encapsulated in a compact silica shell which provides a confined nano-space for the pyrolysis treatment. The in situ generated gases from mesoporous polymer sphere and 2-methylimidazole under pyrolysis diffuse into the pores of mesoporous polymer sphere in the confined compact silica shell,resulting in increased surface area, larger pore size and N-doping due to self-activation effect. As electrodes in supercapacitor, the N-doped mesoporous carbon nanospheres exhibit a significantly enhanced specific capacitance of 326 Fg^-1 at 0.5 Ag^-1, which is 2 times higher than that of mesoporous carbon spheres under unconfined pyrolysis condition, exhibiting its potential for electrode materials with high performance. | Juan Du Lei Liu Yifeng Yu Yue Zhang Haijun Lv Aibing Chen | 2019 | Journal of Materials Science & Technology2019，35，10： | 4 |

| 6 | Regulators of alternative polyadenylation operate at the transition from mitosis to meiosis显示文摘In the sexually reproductive organisms, gametes are produced by meiosis following a limited mitotic amplification. However, the intrinsic program switching cells from mitotic to meiotic cycle is unclear.Alternative polyadenylation(APA) is a highly conserved means of gene regulation and is achieved by the RNA 30-processing machinery to generate diverse 30 UTR profiles. In Drosophila spermatogenesis, we observed distinct profiles of transcriptome-wide 30 UTR between mitotic and meiotic cells. In mutant germ cells stuck in mitosis, 30 UTRs of hundreds of genes were consistently shifted. Remarkably, altering the levels of multiple 30-processing factors disrupted germline's progression to meiosis, indicative of APA's active role in this transition. An RNA-binding protein(RBP) Tut could directly bind 30 UTRs of 30-processing factors whose expressions were repressed in the presence of Tut-containing complex. Further,we demonstrated that this RBP complex could execute the repression post-transcriptionally by recruiting CCR4/Twin of deadenylation complex. Thus, we propose that an RBP complex regulates the dynamic APA profile to promote the mitosis-to-meiosis transition. | Lingjuan Shan Chan Wu Di Chen Lei Hou Xin Li Lixia Wang Xiao Chu Yifeng Hou Zhaohui Wang | 2017 | Journal of Genetics and Genomics2017，44，2： | 1 |
| 7 | Spontaneous movement of a retrotransposon generated genic dominant male sterility providing a useful tool for rice breeding显示文摘Male sterility in plants provides valuable breeding tools in germplasm innovation and hybrid crop production.However,genetic resources for dominant genic male sterility,which hold great promise to facilitate breeding processes,are extremely rare in natural germplasm.Here we characterized the Sanming Dominant Genic Male Sterility in rice and identified the gene SDGMS using a map-based cloning approach.We found that spontaneous movement of a 1978-bp long terminal repeat(LTR)retrotransposon into the promoter region of the SDGMS gene activates its expression in anther tapetum,which causes abnormal programmed cell death of tapetal cells resulting in dominant male sterility.SDGMS encodes a ribosome inactivating protein showing N-glycosidase activity.The activation of SDGMS triggers transcription reprogramming of genes responsive to biotic stress leading to a hypersensitive response which causes sterility.The results demonstrate that an ectopic gene activation by transposon movement can give birth to a novel trait which enriches phenotypic diversity with practical utility. | Conghao Xu Yifeng Xu Zhengji Wang Xiaoyu Zhang Yuying Wu Xinyan Lu Hongwei Sun Lei Wang Qinglu Zhang Qinghua Zhang Xianghua Li Jinghua Xiao Xu Li Mingfu Zhao Yidan Ouyang Xianbo Huang Qifa Zhang | 2023 | National Science Review2023，10，9： | 1 |
| 8 | Pomelo Peel-Inspired 3D-Printed Porous Structure for Efficient Absorption of Compressive Strain Energy显示文摘The porous structure in pomelo peel is believed to be responsible for the protection of its fruit from damage during the free falling from a tree.The quantitative understanding of the relationship between the deformation behavior and the porous structure could pave the way for the design of porous structures for efficient energy absorption.Here,a universal feature of pore distribution in pomelo peels along the radial direction is extracted from three varieties of pomelos,which shows strong correlation to the deformation behavior of the peels under compression.Guided by the porous design found in pomelo peels,porous polyether-ether-ketone(PEEK)cube is additively manufactured and possesses the highest ability to absorb energy during compression as compared to the non-pomelo-inspired geometries,which is further confirmed by the finite element simulation.The nature-optimized porous structure revealed here could guide the design of lightweight and high-energy-dissipating materials/devices. | Baisong Yang Wenhui Chen Renlong Xin Xiaohong Zhou Di Tan Chuan Ding You Wu Liang Yin Chuyang Chen Shan Wang Zhenglei Yu Jonathan TPham Sheng Liu Yifeng Lei Longjian Xue | 2022 | Journal of Bionic Engineering2022，19，2： | 1 |

| 10 | Unraveling the large cell lung carcinoma-specific miRNA profile and the downstream regulation network显示文摘Large cell lung carcinoma(LCLC)is a rare subtype of highly migratory non-small cell lung carcinoma(NSCLC)[1] with resistance of chemotherapy[2],which leads to its poor diagnosis and prognosis in clinical practice[3].Evidence showed that non-coding RNAs participating in tumorigenesis and tumor progression can be potential therapeutic targets iii NSCLC[4].However,due to the low incidence and typical clinical feature of LCLC,knowledge about non-coding RNAs,especially LCLC characteristic miRNAs,their downstream conventional mRNA targets,and the involved lncRNAs is quite limited[5]. | Yifeng Gong Xue Li Lei Deng Li Jin Youxin Jin Yan Jin | 2019 | Acta Biochimica et Biophysica Sinica2019，51，10： | 1 |
| 11 | Synthesis of nitrogen-doped carbon spheres using the modified Stober method for supercapacitors显示文摘Nitrogen-doped carbon spheres (NCSs) with uniform and regular morphology were facilely prepared by the modified Stober method. Hexamethylenetetramine (HMT) was selected as the starting material, which decomposed to provide nitrogen and carbon sources for the synthesis of NCSs. The decomposition product formaldehyde polymerized to form carbon skeleton with resorcinol after carbonization, and the in-situ nitrogen doping was achieved with the decomposed nitrogen source. NCSs were obtained with regular spherical morphology, high specific surface area, and suitable nitrogen doping. When used as the electrode material, NCSs exhibited good capacitance and electrochemical stability, indicating that NCSs be the promising candidate for the electrode material of high-performance supercapacitors. | Meng LIU Lei LIU Yifeng YU Haijun LV Aibing CHEN Senlin HOU | 2019 | Frontiers of Materials Science2019，13，2： | 1 |
| 12 | Defect-rich and ultrathin nitrogen-doped carbon nanosheets with enhanced peroxidase-like activity for the detection of urease activity and fluoride ion显示文摘Although carbon nanozymes have attracted great interest due to their good biocompatibility, low cost,and high stability, designing high-active carbon nanozymes still faces great challenges. Herein, ultrathin nitrogen-doped carbon nanosheets with rich defects(d-NC) were prepared through a high-temperature annealing process, using potassium chloride and ammonium chloride as templates. Owing to the large specific surface area, rich defects and the high exposure of active sites, the proposed d-NC nanozymes exhibited excellent peroxidase-like activity. The d-NC nanozymes possess maximal reaction velocity and their specific activity is 9.4-fold higher than that of nitrogen-doped carbon nanozymes, indicating that the induced defects can boost the catalytic performance. Benefited from the good peroxidase-like activities of d-NC nanozymes, the colorimetric sensing platforms were constructed for the detection of urease activity and fluoride ion, exhibiting satisfactory stability and selectivity. This study not only offers a way to synthesize carbon nanozymes with improved enzyme-like activities but also broadens their applications in colorimetric biosensing. | Yu Zhang Lei Jiao Weiqing Xu Yifeng Chen Yu Wu Hongye Yan Wenling Gu Chengzhou Zhu | 2022 | Chinese Chemical Letters2022，33，3： | 1 |
| 13 | Thermoelectric enhancement of p-type Si_(80)Ge_(20) alloy via co-compositing of dual oxides:Respective regulation for power factor and thermal conductivity byβ-Ga_(2)O_(3) and SiO_(2) aerogel powders显示文摘Si-based thermoelectric(TE)materials are exhibiting remarkable perspectives in self-energized applications with their special advantages.However,the relatively high total thermal conductivity(κ)prevents their TE enhancement.Here,a strategy of co-compositing dual oxides was implemented for enhancing the TE properties of p-type Si_(80)Ge_(20) bulks.Composited Ga2O_(3) was demonstrated to enhance the power factor(PF)due to the crystallization-induced effect of produced Ga by decomposition on SiGe matrix.Associating with compositing SiO_(2) aerogel(a-SiO_(2))powder,not only introduced the fine amorphous inclusions and decreased the grain size of host matrix,but also various nano morphologies were formed,i.e.,nano inclusions,precipitations,twin boundaries(TBs),and faults.Combining with the eutectic Ge,hierarchical scattering centers impeded the phonon transport comprehensively(decreasing the phonon group velocity(a v)and relaxation time)for reducing the lattice-induced thermal conductivity(lκ).As a result,a minimumκof 2.38 W·m^(−1)·K^(−1) was achieved,which is significantly dropped by 32.6%in contrast with that of the pristine counterpart.Ultimately,a maximal dimensionless figure of merit(ZT)of 0.9 was achieved at 600℃,which is better than those of most corresponding oxide-composited Si-based bulks. | Huajun LAI Ying PENG Mengfei WANG Runze SHI Junliang CHEN Chengyan LIU Yifeng WANG Lei MIAO Haiqiao WEI | 2023 | Journal of Advanced Ceramics2023，12，2： | 1 |
| 14 | 'Dissolution-reassembly' for N-doped hollow micro/meso-carbon spheres with high supercapacitor performance显示文摘Herein, we report a 'dissolution-reassembly' approach for preparation of N-doped hollow carbon spheres with mesoporous/microporous composite structure (H(Micro/Meso)CS). Basing on the compositional inhomogeneity inside the nanospheres of 3-aminophenol/formaldehyde (3-AF) polymerization, the internal 3-AF oligomer with low-molecular-weight is dissolved by acetone to form cavity. Then the dispersive 3-AF oligomer reassemble with silica oligomer as pore-forming agent and cetyltrimethyl-ammonium bromide as surfactant to form a mesoporous outer shell. In addition, the amount of acetone has a great influence on the morphology and structure of H(Micro/Meso)CS. The obtained H(Micro/Meso)CS shows uniform spherical and microporous/mesoporous shell structure and has a high specific capacity and excellent high rate capability. | Juan Du Lei Liu Yifeng Yu Yue Zhang Aibing Chen | 2019 | Chinese Chemical Letters2019，30，7： | 1 |
| 15 | Heterointerface Engineering of β‑Chitin/Carbon Nano‑Onions/Ni-P Composites with Boosted Maxwell‑Wagner‑Sillars Effect for Highly Efficient Electromagnetic Wave Response and Thermal Management显示文摘The rational construction of microstructure and composition with enhanced Maxwell-Wagner-Sillars effect(MWSE)is still a challenging direction for reinforcing electromagnetic wave(EMW)absorption performance,and the related EMW attenuation mechanism has rarely been elucidated.Herein,MWSE boostedβ-chitin/carbon nano-onions/Ni–P composites is prepared according to the heterointerface engineering strategy via facile layer-by-layer electrostatic assembly and electroless plating techniques.The heterogeneous interface is reinforced from the aspect of porous skeleton,nanomaterials and multilayer construction.The composites exhibit competitive EMW response mechanism between the conductive loss and the polarization/magnetic loss,as describing like the story of“The Hare and the Tortoise”.As a result,the composites not only achieve a minimum reflection loss(RL_(min))of−50.83 dB and an effective bandwidth of 6.8 GHz,but also present remarkable EMW interference shielding effectiveness of 66.66 dB.In addition,diverse functions such as good thermal insulation,infrared shielding and photothermal performance were also achieved in the hybrid composites as a result of intrinsic morphology and chemicophysics properties.Therefore,we believe that the boosted MWSE open up a novel orientation toward developing multifunctional composites with high-efficient EMW response and thermal management. | Fei Pan Lei Cai Yuyang Shi Yanyan Dong Xiaojie Zhu Jie Cheng Haojie Jiang Xiao Wang Yifeng Jiang Wei Lu | 2022 | Nano-Micro Letters2022，14，5： | 1 |

| 18 | ZIF-derived mesoporous carbon materials prepared by activation via Na_(2)SiO_(3) for supercapacitor显示文摘Metal organic frameworks(MOFs)derived carbonaceous materials have a wide range of applications in the fields of energy storage,catalysis,adsorption and separation,etc.Especially,zeolitic imidazolate framework-8(ZIF-8)is an excellent candidate to synthesize porous carbon due to the large surface area and high nitrogen content.However,the dominated microporous structure of ZIF-8-derived carbon significantly hinders ionic mass trans fer,limiting the improvement of performance.Herein,MOF-derived mesoporous carbon was prepared using ZIF-8 as carbon precursor and cheap sodium silicate(Na_(2)SiO_(3))as activator.The introduction of Na_(2)SiO_(3) created rich mesoporous structure and increased specific surface area,as well as the effects of pyrolysis temperature and Na_(2)SiO_(3) dosage on performance was also investigated.The obtained ZIF-derived porous carbon exhibits good electrochemical performance with specific capacitance of 263 F/g at 1 A/g and excellent cycle life(96.07%after 10,000 GCD cycles)in supercapacitor.The use of cheap Na_(2)SiO_(3) activator provides a new orientation for the preparation of MOF-derived carbons with rich pores,high surface area,and facilitates the large-scale application of MOF-derived carbons. | Chang Ma Yahui Mo Lei Liu Yifeng Yu Aibing Chen | 2021 | Chinese Chemical Letters2021，32，4： | 1 |
| 19 | Improving the data retention of phase change memory by using a doping element in selected Ge_2Sb_2Te_5显示文摘The crystallization characteristics of a ubiquitous T-shaped phase change memory(PCM) cell, under SET current pulse and very small disturb current pulse, have been investigated by finite element modelling. As analyzed in this paper, the crystallization region under SET current pulse presents first on the corner of the bottom electron contact(BEC) and then promptly forms a filament shunting down the amorphous phase to achieve the low-resistance state, whereas the tiny disturb current pulse accelerates crystallization at the axis of symmetry in the phase change material. According to the different crystallization paths, a new structure of phase change material layer is proposed to improve the data retention for PCM without impeding SET operation.This structure only requires one or two additional process steps to dope nitrogen element in the center region of phase change material layer to increase the crystallization temperature in this confined region. The electrical-thermal characteristics of PCM cells with incremental doped radius have been analyzed and the best performance is presented when the doped radius is equal to the radius of the BEC. | Yaoyao Lu Daolin Cai Yifeng Chen Shuai Yan Lei Wu Yuanguang Liu Yang Li Zhitang Song | 2019 | Journal of Semiconductors2019，40，4： | 0 |
| 20 | Screening of immune cell activators from Astragali Radix using a comprehensive two-dimensional NK-92MI cell membrane chromatography/C18 column/time-of-flight mass spectrometry system显示文摘Astragali Radix(AR)is a clinically used herbal medicine with multiple immunomodulatory activities that can strengthen the activity and cytotoxicity of natural killer(NK)cells.However,owing to the complexity of its composition,the specific active ingredients in AR that act on NK cells are not clear yet.Cell membrane chromatography(CMC)is mainly used to screen the active ingredients in a complex system of herbal medicines.In this study,a new comprehensive two-dimensional(2D)NK-92MI CMC/C18 column/time-of-flight mass spectrometry(TOFMS)system was established to screen for potential NK cell activators.To obtain a higher column efficiency,3-mercaptopropyltrimethoxysilane-modified silica was synthesized to prepare the NK-92MI CMC column.In total,nine components in AR were screened from this system,which could be washed out from the NK-92MI/CMC column after 10 min,and they showed good affinity for NK-92MI/CMC column.Two representative active compounds of AR,isoastragaloside Ⅰ and astragaloside IV,promoted the killing effect of NK cells on K562 cells in a dose-dependent manner.It can thus suggest that isoastragaloside Ⅰ and astragaloside Ⅳ are the main immunomodulatory components of AR.This comprehensive 2D NK-92MI CMC analytical system is a practical method for screening immune cell activators from other herbal medicines with immunomodulatory effects. | Xinyi Chai Yanqiu Gu Lei Lv Chun Chen Fei Feng Yan Cao Yue Liu Zhenyu Zhu Zhanying Hong Yifeng Chai Xiaofei Chen | 2022 | Journal of Pharmaceutical Analysis2022，12，5： | 0 |
