| 1 | Selective hydrogenation of CO2 to methanol over Ni/In2O3 catalyst显示文摘An In2O3 supported nickel catalyst has been prepared by wet chemical reduction with sodium borohydride(NaBH4) as a reducing agent for selective hydrogenation of carbon dioxide to methanol. Highly dispersed Ni species with intense Ni-In2O3 interaction and enhanced oxygen vacancies have been achieved.The highly dispersed Ni species serve as the active sites for hydrogen activation and hydrogen spillover.Abundant H adatoms are thereby generated for the oxygen vacancy creation on the In2O3 surface. The enhanced surface oxygen vacancies further lead to improved CO2 conversion. As a result, an effective synergy between the active Ni sites and surface oxygen vacancies on In2O3 causes a superior catalytic performance for CO2 hydrogenation with high methanol selectivity. Carbon monoxide is the only by product detected. The formation of methane can be ignored. When the reaction temperature is lower than 225 ℃,the selectivity of methanol is 100%. It is higher than 64% at the temperature range between 225 ℃ and 275 ℃. The methanol selectivity is still higher than 54% at 300 ℃ with a CO2 conversion of 18.47% and a methanol yield of 0.55 gMeOHg-1cath-1(at 5 MPa). The activity of Ni/In2O3 is higher than most of the reported In2O3-based catalysts. | Xinyu Jia Kaihang Sun Jing Wang Chenyang Shen Chang-jun Liu | 2020 | Journal of Energy Chemistry2020,29,11: | 13 |
| 2 | Crustal accretion and reworking processes of micro-continental massifs within orogenic belt:A case study of the Erguna Massif,NE China显示文摘This paper summarizes the geochronological, geochemical and zircon Hf isotopic data for Mesozoic granitoids within the Erguna Massif, NE China, and discusses the spatial-temporal variation of zircon Hf isotopic compositions, with the aim of constraining the accretion and reworking processes of continental crust within the Erguna Massif, and shedding light on the crustal evolution of the eastern segment of the Central Asian Orogenic Belt. Based on the zircon U-Pb dating results, the Mesozoic granitic magmatisms within the Erguna Massif can be subdivided into five stages: Early-Middle Triassic(249–237 Ma), Late Triassic(229–201 Ma), Early-Middle Jurassic(199–171 Ma), Late Jurassic(155–149 Ma), and Early Cretaceous(145–125 Ma).The Triassic to Early-Middle Jurassic granitoids are mainly I-type granites and minor adakitic rocks, whereas the Late Jurassic to Early Cretaceous granitoids are mainly A-type granites. This change in magmatism is consistent with the southward subduction of the Mongol-Okhotsk oceanic plate and subsequent collision and crustal thickening, followed by post-collision extension. Zircon Hf isotopic data indicate that crustal accretion of the Erguna Massif occurred in the Mesoproterozoic and Neoproterozoic. ZirconεHf(t) values increase gradually over time, whereas two-stage model(TDM2) ages decrease throughout the Mesozoic. The latter result indicates a change in the source of granitic magmas from the melting of ancient crust to more juvenile crust. Zircon εHf(t)values also exhibit spatial variations, with values decreasing northwards, whereas TDM2 ages increase. This pattern suggests that,moving from south to north, there is an increasing component of ancient crustal material within the lower continental crust of the Erguna Massif. Even if at the same latitude, the zircon Hf isotopic compositions are also inconsistent. These results reveal lateral and vertical heterogeneities in the lower continental crust of the Erguna Massif during the Mesozoic, which we use as the basis of a structural and tectonic model for this region. | SUN ChenYang TANG Jie XU WenLiang LI Yu ZHAO Shuo | 2017 | Science China Earth Sciences2017,60,7: | 10 |
| 3 | Total phenolic, flavonoid content, and antioxidant activity of flour, noodles, and steamed bread made from different colored wheat grains by three milling methods显示文摘The objective of this study was to evaluate the effects of wheat variety, food processing, and milling method on antioxidant properties. Black wheat variety Heibaoshi 1 had the highest total phenolic content(659.8 μg gallic acid equivalents g-1), total flavonoid content(319.3 μg rutin equivalents g-1), and antioxidant activity, whereas light purple wheat variety Shandongzimai 1 had the lowest total flavonoid content(236.2 μg rutin equivalents g-1) and antioxidant activity. Whole wheat flour and partially debranned grain flour had significantly higher total phenolic contents, total flavonoid contents, and antioxidant activity than refined flour(P < 0.05). Compared with flour, total phenolic contents, total flavonoid contents and antioxidant activity decreased in noodles and steamed bread, whereas noodles had slightly higher total phenolic and flavonoid content than steamed bread. Antioxidant activities(by ferric reducing ability of plasma assay) of steamed bread made from whole wheat flour, partially debranned grain flour, and refined flour were 23.5%, 21.1%, and 31.6% lower, respectively, than the corresponding values of flour. These results suggested that black whole wheat flour and partially debranned grain flour are beneficial to human health. | Yaoguang Li Dongyun Ma Dexiang Sun Chenyang Wang Jian Zhang Yingxin Xie Tiancai Guo | 2015 | The Crop Journal2015,3,4: | 7 |
| 4 | Visible-light-driven heterostructured g-C_(3)N_(4)/Bi-TiO_(2) floating photocatalyst with enhanced charge carrier separation for photocatalytic inactivation of Microcystis aeruginosa显示文摘The increase in occurrence and severity of cyanobacteria blooms is causing increasing concern;moreover,human and animal health is affected by the toxic effects of Microcystin-LR released into the water.In this paper,a floating photocatalyst for the photocatalytic inactivation of the harmful algae Microcystis aeruginosa(M.aeruginosa)was prepared using a simple sol-gel method,i.e.,coating g-C_(3)N_(4) coupled with Bi-doped TiO_(2) on Al_(2)O_(3)-modified expanded perlite(CBTA for short).The impact of different molar ratios of Bi/Ti on CBTA was considered.The results indicated that Bi doping in TiO_(2) inhibited photogenerated electron-hole pair recombination.With 6 h of visible light illumination,75.9%of M.aeruginosa(initial concentration=2.7106 cells/L)and 83.7%of Microcystin-LR(initial concentration=100μg/L)could be removed with the addition of 2 g/L CBTA1%(i.e.,Bi/Ti molar ratio=1%).The key reactive oxygen species(ROSs)in the photocatalytic inactivation process are h+andOH.The induction of the Bi^(4+)/Bi^(3+)species by the incorporation of Bi could narrow the bandgap of TiO_(2),trap electrons,and enhance the stability of CBTA-1%in the solutions with coexisting environmental substances. | Jingke Song Chenyang Li Xuejiang Wang Songsong Zhi Xin Wang Jianhui Sun | 2021 | Frontiers of Environmental Science & Engineering2021,15,6: | 5 |
| 5 | Wheat breeding history reveals synergistic selection of pleiotropic genomic sites for plant architecture and grain yield显示文摘Diversity surveys of crop germplasm are important for gaining insights into the genomic basis for plant architecture and grain yield improvement,which is still poorly understood in wheat.In this study,we exome sequenced 287 wheat accessions that were collected in the past 100 years.Population genetics analysis identified that 6.7%of the wheat genome falls within the selective sweeps between landraces and cultivars,which harbors the genes known for yield improvement.These regions were asymmetrically distributed on the A and B subgenomes with regulatory genes being favorably selected.Genome-wide association study(GWAS)identified genomic loci associated with traits for yield potential,and two underlying genes,TaARF12 encoding an auxin response factor and TaDEP1 encoding the G-proteinγ-subunit,were located and characterized to pleiotropically regulate both plant height and grain weight.Elite single-nucleotide haplotypes with increased allele frequency in cultivars relative to the landraces were identified and found to have accumulated over the course of breeding.Interestingly,we found that TaARF12 and TaDEP1 function in epistasis with the classical plant height Rht-1 locus,leading to propose a“Green Revolution”-based working model for historical wheat breeding.Collectively,our study identifies selection signatures that fine-tune the gibberellin pathway during modern wheat breeding and provides a wealth of genomic diversity resources for the wheat research community. | Aili Li Chenyang Hao Zhenyu Wang Shuaifeng Geng Meiling Jia Fang Wang Xiang Han Xingchen Kong Lingjie Yin Shu Tao Zhongyin Deng Ruyi Liao Guoliang Sun Ke Wang Xingguo Ye Chengzhi Jiao Hongfeng Lu Yun Zhou Dengcai Liu Xiangdong Fu Xueyong Zhang Long Mao | 2022 | Molecular Plant2022,15,3: | 4 |
| 6 | Arabidopsis E3 ligase KEG associates with and ubiquitinates MKK4 and MKK5 to regulate plant immunity显示文摘Mitogen-activated protein kinase(MAPK) cascades are highly conserved signaling modules that regulate plant immune responses. The Arabidopsis thaliana Raf-like MAPK kinase kinase ENHANCED DISEASE RESISTANCE1(EDR1) is a key negative regulator of plant immunity that affects the protein levels of MKK4 and MKK5, two important MAPK cascade members, but the underlying mechanism is poorly understood. Here, genome-wide phosphorylation analysis demonstrated that the E3 ligase KEEP ON GOING(KEG) is phosphorylated in the edr1 mutant but not the wild type, suggesting that EDR1 negatively affects KEG phosphorylation. The identified phosphorylation sites in KEG appear to be important for its accumulation. The keg-4 mutant, a previously identified edr1 suppressor, enhances susceptibility to the powdery mildew pathogen Golovinomyces cichoracearum. In addition, MKK4 and MKK5 protein levels are reduced in the keg-4 mutant. Furthermore,we demonstrate that MKK4 and MKK5 associate with full-length KEG, but not with truncated KEG-RK or KEG-RKA, and that KEG ubiquitinates and mediates the degradation of MKK4 and MKK5. Taken together, these results indicate that MKK4 and MKK5 protein levels are regulated by KEG via ubiquitination, uncovering a mechanism by which plants finetune immune responses by regulating the homeostasis of key MAPK cascade members via ubiquitination and degradation. | Chenyang Gao Pengwei Sun Wei Wang Dingzhong Tang | 2021 | Journal of Integrative Plant Biology2021,63,2: | 4 |
| 7 | Crustal Accretion and Reworking within the Khanka Massif: Evidence from Hf Isotopes of Zircons in Phanerozoic Granitoids显示文摘This paper presents a synthesis and analysis of geochronological, geochemical, and zircon Hf isotopic data of Phanerozoic granitoids within the Khanka massif, with the aim of revealing the accretion and reworking processes of continental crust within the massif. Zircon U-Pb dating indicates that Phanerozoic granitic magmatism within the Khanka massif can be subdivided into eight stages: Late Cambrian, Middle–Late Ordovician, Middle Silurian, Late Carboniferous, Early Permian, Middle–Late Permian to Early Triassic, Late Triassic–Early Jurassic, and Early Cretaceous. The zircon Hf isotopic compositions reveal that crustal accretionary events took place mainly in the Mesoproterozoic and Neoproterozoic. Through time, the zircon ε_(Hf)(t) values gradually increase, indicating that the Phanerozoic granitic magmas were derived from the melting of progressively less ancient and more juvenile crust. The zircon ε_(Hf)(t) values exhibit a gradual decrease with the increases in latitude, which implies that the amounts of ancient crustal components within the lower continental crust of the Khanka massif increased from south to north. At the same latitude range, the zircon Hf isotopic compositions also display some variations. We conclude, therefore, that significant horizontal and vertical heterogeneities existed in the lower continental crust of the Khanka massif during the Phanerozoic. | Xiaoming Zhang Wenliang Xu Chenyang Sun Ting Xu Feng Wang | 2018 | Journal of Earth Science2018,29,2: | 3 |
| 8 | The feasibility study of the indium oxide supported silver catalyst for selective hydrogenation of CO_(2)to methanol显示文摘Silver catalyst has been extensively investigated for photocatalytic and electrochemical CO_(2) reduction.However,its high activity for selective hydrogenation of CO_(2) to methanol has not been confirmed.Here,the feasibility of the indium oxide supported silver catalyst was investigated for CO_(2) hydrogenation to methanol by the density functional theoretical(DFT)study and then by the experimental investigation.The DFT study shows there exists an intense Ag-In_(2)O_(3) interaction,which causes silver to be positively charged.The positively charged Ag species changes the electronic structure of the metal,facilitates the formation of the Ag-In_(2)O_(3) interfacial site for activation and dissociation of carbon dioxide.The promoted CO_(2) dissociation leads to the enhanced methanol synthesis via the CO hydrogenation route as CO_(2)^(*)→CO^(*)→HCO^(*)→H_(2)CO^(*)→H_(3)CO^(*)→H_(3)COH^(*).The Ag/In_(2)O_(3)catalyst was then prepared using the deposition-precipitation method.The experimental study confirms the theoretical prediction.The methanol selectivity of CO_(2) hydrogenation on Ag/In_(2)O_(3) reaches 100.0%at reaction temperature of 200℃.It remains more than 70.0%between 200 and 275℃.At 300℃and 5 MPa,the methanol selectivity still keeps 58.2%with a CO_(2) conversion of 13.6%and a space-time yield(STY)of methanol of 0.453 g_(methanol)g_(cat)^(-1)h^(-1),which is the highest methanol STY ever reported for silver catalyst.The catalyst characterization confirms the intense Ag-In_(2)O_(3)interaction as well,which causes high Ag dispersion,increases and stabilizes the oxygen vacancies and creates the active Ag-In_(2)O_(3)interfacial site for the enhanced CO_(2)hydrogenation to methanol. | Kaihang Sun Zhitao Zhang Chenyang Shen Ning Rui Chang-jun Liu | 2022 | Green Energy & Environment2022,7,4: | 2 |
| 9 | Recent Advances in Two-Dimensional Magnets:Physics and Devices towards Spintronic Applications显示文摘The emergence of low-dimensional nanomaterials has brought revolutionized development of magnetism,as the size effect can significantly influence the spin arrangement.Since the first demonstration of truly two-dimensional magnetic materials(2DMMs)in 2017,a wide variety of magnetic phases and associated properties have been exhibited in these 2DMMs,which offer a new opportunity to manipulate the spin-based devices efficiently in the future.Herein,we focus on the recent progress of 2DMMs and heterostructures in the aspects of their structural characteristics,physical properties,and spintronic applications.Firstly,the microscopy characterization of the spatial arrangement of spins in 2D lattices is reviewed.Afterwards,the optical probes in the light-matter-spin interactions at the 2D scale are discussed.Then,particularly,we systematically summarize the recent work on the electronic and spintronic devices of 2DMMs.In the section of electronic properties,we raise several exciting phenomena in 2DMMs,i.e.,long-distance magnon transport,field-effect transistors,varying magnetoresistance behavior,and(quantum)anomalous Hall effect.In the section of spintronic applications,we highlight spintronic devices based on 2DMMs,e.g.,spin valves,spin-orbit torque,spin field-effect transistors,spin tunneling field-effect transistors,and spin-filter magnetic tunnel junctions.At last,we also provide our perspectives on the current challenges and future expectations in this field,which may be a helpful guide for theorists and experimentalists who are exploring the optical,electronic,and spintronic properties of 2DMMs. | Vertikasari PNingrum Bowen Liu Wei Wang Yao Yin Yi Cao Chenyang Zha Hongguang Xie Xiaohong Jiang Yan Sun Sichen Qin Xiaolong Chen Tianshi Qin Chao Zhu Lin Wang Wei Huang | 2020 | Research2020,,1: | 2 |
| 10 | A branched dihydrophenazine-based polymer as a cathode material to achieve dual-ion batteries with high energy and power density显示文摘Organic electrode materials have exhibited good electrochemical performance in batteries,but their voltages and rate capabilities still require improvement to meet the increasing demand for batteries with high energy and power density.Herein,we design and synthesize a branched dihydrophenazine-based polymer(p-TPPZ)as a cathode material for dual-ion batteries(DIBs)through delicate molecular design.Compared with the linear dihydrophenazine-based polymer(p-DPPZ,with a theoretical capacity of 209 mAh g^(−1)),p-TPPZ possessed a higher theoretical capacity of 233 mAh g^(−1)and lower highest occupied molecular orbital energy levels,which resulted in a high actual capacity(169.3 mAh g^(−1)at 0.5 C),an average discharge voltage of 3.65 V(vs.Li+/Li)and a high energy density(618.2 Wh kg^(−1),based on the cathode materials).The branched structure of p-TPPZ led to a larger specific surface area than that of p-DPPZ,which was beneficial for the electrolyte infiltration and fast ionic transport,contributing to the high power density.Due to the fast reaction kinetics,even at a power density of 23,725 W kg^(−1)(40 C),the energy density still reached 474.5 Wh kg^(−1).We also made a detailed investigation of the p-TPPZ cathode’s charge storage mechanism.This work will stimulate the further molecular design to develop organic batteries with both high energy and power density. | Shuaifei Xu Huichao Dai Shaolong Zhu Yanchao Wu Mingxuan Sun Yuan Chen Kun Fan Chenyang Zhang Chengliang Wang Wenping Hu | 2021 | eScience2021,1,1: | 2 |
| 11 | Synergistic effect of the metal-support interaction and interfacial oxygen vacancy for CO_(2) hydrogenation to methanol over Ni/In_(2)O_(3) catalyst:A theoretical study显示文摘Indium oxide supported nickel catalyst has been experimentally confirmed to be highly active for CO_(2) hydrogenation towards methanol.In this work,the reaction mechanism for CO_(2) hydrogenation to methanol has been investigated on a model Ni/In_(2)O_(3) catalyst,i.e.,Ni_(4)/In_(2)O_(3),via the density functional theory(DFT)study.Three possible reaction pathways,i.e.,the formate pathway,CO hydrogenation and the reverse water-gas-shift(RWGS)pathways,have been examined on this model catalyst.It has been demonstrated that the RWGS pathway is the most theoretically-favored for CO_(2) hydrogenation to methanol.The complete RWGS pathway follows CO_(2)+6 H→COOH+5 H→CO+H_(2)O+4 H→HCO+H_(2)O+3 H→H_(2)CO+H_(2)O+2 H→H_(3)CO+H_(2)O+H→H_(3)COH+H_(2) O.Furthermore,it has been also proved that the interfacial oxygen vacancy can serve as the active site for boosting the CO_(2) adsorption and charge transfer between the nickel species and indium oxide,which synergistically promotes the consecutive CO_(2) hydrogenation towards methanol. | Chenyang Shen Qianqian Bao Wenjuan Xue Kaihang Sun Zhitao Zhang Xinyu Jia Donghai Mei Chang-jun Liu | 2022 | Journal of Energy Chemistry2022,31,2: | 2 |

| 13 | Recent Advances in Molybdenum-Based Materials for Lithium-Sulfur Batteries显示文摘Lithium-sulfur(Li-S)batteries as power supply systems possessing a theoretical energy density of as high as 2600 Wh kg−1 are considered promising alternatives toward the currently used lithium-ion batteries(LIBs).However,the insulation characteristic and huge volume change of sulfur,the generation of dissolvable lithium polysulfides(LiPSs)during charge/discharge,and the uncontrollable dendrite formation of Li metal anodes render Li-S batteries serious cycling issues with rapid capacity decay.To address these challenges,extensive efforts are devoted to designing cathode/anode hosts and/or modifying separators by incorporating functional materials with the features of improved conductivity,lithiophilic,physical/chemical capture ability toward LiPSs,and/or efficient catalytic conversion of LiPSs.Among all candidates,molybdenum-based(Mo-based)materials are highly preferred for their tunable crystal structure,adjustable composition,variable valence of Mo centers,and strong interactions with soluble LiPSs.Herein,the latest advances in design and application of Mo-based materials for Li-S batteries are comprehensively reviewed,covering molybdenum oxides,molybdenum dichalcogenides,molybdenum nitrides,molybdenum carbides,molybdenum phosphides,and molybdenum metal.In the end,the existing challenges in this research field are elaborately discussed. | Henghan Dai Lumin Wang Yue Zhao Jialu Xue Ruicong Zhou Chenyang Yu Jianing An Jinyuan Zhou Qiang Chen Gengzhi Sun Wei Huang | 2021 | Research2021,,1: | 1 |
| 14 | Mixed secondary chromatin structure revealed by modeling radiation-induced DNA fragment length distribution显示文摘Spatial chromatin structure plays fundamental roles in many vital biological processes including DNA replication, transcription,damage and repair. However, the current understanding of the secondary structure of chromatin formed by local nucleosomenucleosome interactions remains controversial, especially for the existence and conformation of 30 nm structure. Since chromatin structure influences the fragment length distribution(FLD) of ionizing radiation-induced DNA strand breaks, a 3D chromatin model fitting FLD patterns can help to distinguish different models of chromatin structure. Here, we developed a novel '30-C' model combining 30 nm chromatin structure models with Hi-C data, which measured the spatial contact frequency between different loci in the genome. We first reconstructed the 3D coordinates of the 25 kb bins from Hi-C heatmaps. Within the25 kb bins, lower level chromatin structures supported by recent studies were filled. Simulated FLD patterns based on the 30-C model were compared to published FLD patterns induced by heavy ion radiation to validate the models. Importantly, the 30-C model predicted that the most probable chromatin fiber structure for human interphase fibroblasts in vivo was 45% zig-zag 30 nm fibers and 55% 10 nm fibers. | Wenzong Ma Chenyang Gu Lin Ma Caoqi Fan Chao Zhang Yujie Sun Cheng Li Gen Yang | 2020 | Science China(Life Sciences)2020,63,6: | 1 |

| 16 | Hydrogenation Behavior of Hydrogen Peroxide in a Microreactor显示文摘The hydrogenation of hydrogen peroxide is an unwanted side reaction in the direct synthesis of hydrogen peroxide and remains a problem to solve.The mechanism of this reaction has been studied with batch reactors but the slow heat and mass transfer in batch reactors hindered the understanding of its intrinsic kinetics.In this study,a microreactor is employed to investigate the parameters that influence the hydrogenation reaction,including flow rate,channel length,hydrogen pressure,solvent composition,and initial hydrogen peroxide concentration.The activity of different catalysts was compared and the hydrogenation law was confirmed,providing guiding information to better control the hydrogenation process. | Zhu Hongwei Sun Bing Jin Yan Feng Junjie Zhao Chenyang Yan Junjie Jiang Jie Xu Wei | 2022 | China Petroleum Processing & Petrochemical Technology2022,24,4: | 1 |
| 17 | Mesh-like vertical structures enable both high areal capacity and excellent rate capability显示文摘In order to balance electrochemical kinetics with loading level for achieving efficient energy storage with high areal capacity and good rate capability simultaneously for wearable electronics,herein,2 D meshlike vertical structures(NiCo_2 S_4@Ni(OH)_2) with a high mass loading of 2.17 mg cm^(-2) and combined merits of both 1 D nanowires and 2 D nanosheets are designed for fabricating flexible hybrid supercapacitors.Particularly,the seamlessly interconnected NiCo_2 S_4 core not only provides high capacity of 287.5 μAh cm^(-2) but also functions as conductive skeleton for fast electron transport;Ni(OH)_2 sheath occupying the voids in NiCo_2 S_4 meshes contributes extra capacity of 248.4 μAh cm^(-2);the holey features guarantee rapid ion diffusion along and across NiCO_2 S_4@Ni(OH)_2 meshes.The resultant flexible electrode exhibits a high areal capacity of 535.9 μAh cm^(-2)(246.9 mAh g^(-1)) at 3 mA cm^(-2) and outstanding rate performance with 84.7% retention at 30 mA cm^(-2),suggesting efficient utilization of both NiCo_2 S_4 and Ni(OH)_2 with specific capacities approaching to their theoretical values.The flexible solid-state hybrid device based on NiCo_2 S_4@Ni(OH)_2 cathode and Fe_2 O_3 anode delivers a high energy density of 315 μWh cm^(-2) at the power density of 2.14 mW cm^(-2) with excellent electrochemical cycling stability. | Ruyi Chen Jialu Xue Yujiao Gong Chenyang Yu Zengyu Hui Hai Xu Yue Sun Xi Zhao Jianing An Jinyuan Zhou Qiang Chen Gengzhi Sun Wei Huang | 2021 | Journal of Energy Chemistry2021,30,2: | 1 |
| 18 | Simulation and experimental study on the surface morphology and energy lost of the target material under non-overlapping impact of angular particles显示文摘In order to further understand the effect of solid impurities on pipeline wall during erosion,the particle impact process without fluid was extracted for specific study.The effect of multi-impact particles on the wall of pipeline was studied experimentally and simulated.In this experiment,an improved ejection apparatus was implemented to carry out multi-impacts non-overlapping impingement by rhombic particles made of high speed steel(W18Cr4V)on the AA6061 aluminum alloy plate through changing particle angle,incident angle,orientation angle and impact velocity.As a result,each particle's penetration depth was investigated and particles' rebound trajectory can be described through this experiment as well as surface morphology of the target material after impingement.The ductile damage criterion,shear damage criterion and MSFLD damage criterion were jointly implemented in ABAQUS/CAE software to simulate the whole process of collision which proved to be effective by getting consistent result compared with experimental data.It is found that under the condition of continuous non-overlapping impact,the target material produces a small work hardening effect in the impact area by converting kinetic energy of moving particles into internal energy of plate so as to reduce the penetration depth of each impact particle. | Xuewen Cao Chenyang Fu Zhenqiang Xie Chao Wu Xiaoyang Sun | 2021 | Chinese Journal of Chemical Engineering2021,34,1: | 1 |
| 19 | E2F is required for STAT3-mediated upregulation of cyclin B1 and Cdc2 expressions and contributes to G2–M phase transition显示文摘Activation of transcription factor STAT3 is involved in cell proliferation,differentiation,and cell survival.Constitutive activation of STAT3 pathway has been associated with the oncogenesis of various types of cancers.It has been reported that STAT3 plays a key role in the G1 to S phase cell cycle transition induced by the cytokine receptor subunit gp130,through the upregulation of cyclins D1,D2,D3,A,and Cdc25A and the concomitant downregulation of p21 and p27.However,its role in mediating G2–M phase transition has not been studied.The cyclin B1/Cdc2 complex is widely accepted as the trigger of mitosis in all organisms and is believed to be necessary for progression through S phase and keep active during the G2–M transition and progression.In the present study,we found that activation of STAT3 stimulates cyclin B1 and Cdc2 expressions.Deletion and site-directed mutations on cyclin B1 and Cdc2 promoters indicated that E2F element mediates the upregulation of these two promoters in a STAT3-dependent manner.The findings reported here demonstrated that STAT3 participates in modulating G2–M phase checkpoint by regulating gene expressions of cyclin B1 and Cdc2 via E2F. | Jingjie Sun Yuping Du Qiaoling Song Jing Nan Peizhu Guan Jihui Guo Xiao Wang Jinbo Yang Chenyang Zhao | 2019 | Acta Biochimica et Biophysica Sinica2019,51,3: | 1 |
