| 1 | Deep carbon cycles constrained by a large-scale mantle Mg isotope anomaly in eastern China显示文摘Although deep carbon recycling plays an important role in the atmospheric CO_2 budget and climate changes through geological time,the precise mechanisms remain poorly understood.Since recycled sedimentary carbonate through plate subduction is the main light-δ^(26)Mg reservoir within deep-Earth,Mg isotope variation in mantle-derived melts provides a novel perspective when investigating deep carbon cycling.Here,we show that the Late Cretaceous and Cenozoic continental basalts from 13 regions covering the whole of eastern China have low δ^(26)Mg isotopic compositions,while the Early Cretaceous basalts from the same area and the island arc basalts from circum-Paciic subduction zones have mantle-like or heavy Mg isotopic characteristics.hus,a large-scale mantle low δ^(26)Mg anomaly in eastern China has been delineated,suggesting the contribution of sedimentary carbonates recycled into the upper mantle,but limited into the lower mantle.his large-scale spatial and temporal variation of Mg isotopes in the mantle places severe constraints on deep carbon recycling via oceanic subduction. | Shu-Guang Li Wei Yang Shah Ke Xunan Meng Hengci Tian Lijuan Xu Yongsheng He Jian Huang Xuan-Ce Wang Qunke Xia Weidong Sun Xiaoyong Yang Zhong-Yuan Ren Haiquan Wei Yongsheng Liu Fancong Meng Jun Yan | 2017 | National Science Review2017，4，1： | 23 |
| 2 | A Nonlinear Control Algorithm for Flywheel Energy Storage Systems in Discharging Mode显示文摘针对Buck-Boost变换器的非线性特征给飞轮储能系统的放电运行状态带来的控制问题,提出了电压电流双环非线性控制算法。基于输入/输出线性化理论,推导出电流内环的控制律,并证明了内动态的稳定性。电压外环采用鲁棒性强的滑模变结构控制方法,并增加限流环节,保证放电电路安全、稳定运行。在Matlab/Simulink仿真平台中搭建飞轮放电模型,对所提出非线性控制算法进行了仿真验证。仿真结果表明,相比于双环PI控制,该算法能够明显改善输出电压调节时间、超调量等动态特性,在输入电压存在大范围变化的情况下,输出电压能够保持恒定和较低的纹波系数。 | WANG Nana Li Yongli ZHANG Weiya CHANG Xiaoyong XUE Wei | 2013 | 中国电机工程学报2013，33，19： | 11 |
| 3 | Impacts of changed litter inputs on soil CO_2 efflux in three forest types in central south China显示文摘Climate change is expected to cause the alteration of litter production in forests,which may result in substantial changes in soil CO2 efflux (FCO2) process as litter represents a major pathway of carbon from vegetation to the soils.In this study,we conducted an aboveground litter manipulation experiment to examine the influence of litter addition and exclusion on soil FCO2 in Camphor tree,Masson pine,and mixed Camphor tree and Masson pine forests in central south China.Litter input manipulation included three treatments:non-litter input (litter exclusion),double litter input (litter addition),and natural litter input (control).On average,litter exclusion significantly reduced soil FCO2 rate by approximately 39%,24% and 22% in Camphor tree forests,the Mixed forests,and Masson pine forests,respectively.On a yearly basis,double litter addition significantly increased soil CO2 by 12% in the Mixed forests (P=0.02) but not in both Camphor tree and Masson pine forests (P>0.05),when compared with their corresponding control treatments.However,litter addition increased soil FCO2 rates in the months of June-August in Camphor tree and Masson pine forests,coinciding with high soil temperature of summer conditions.Litter exclusion reduced soil FCO2 more than litter addition increased it in the study sites.Responses of soil respiration to litter input treatments varied with forest types.Litter input treatments did not alter the seasonal patterns of soil temperature and soil water content.Our results indicated that changes in aboveground litter as a result of global climate change and/or forest management have a great potential to alter soil respiration and soil carbon balance in forest ecosystems. | YAN WenDe CHEN XiaoYong TIAN DaLun PENG YuanYing WANG GuangJun ZHENG Wei | 2013 | Science China(Technological Sciences)2013，56，3： | 11 |
| 4 | Synthesis, nematicidal activity and docking study of novel chromone derivatives containing substituted pyrazole显示文摘A series of chromone derivatives containing substituted pyrazole were designed and synthesized.Preliminary bioassays showed that most of the synthesized compounds exhibited good nematicidal activity in vivo against Meloidogyne incognita at 10 mg/L. Among the tested compounds, A10 and A11 exhibited 100% inhibition rates. In addition, the molecular docking results indicated that both compound A10 and A11 interacts with amino acid residue Tyr121, Trp279, Tyr70, Trp84 and Phe330 of ACh E via hydrogen bond and p–p stacking. This investigation suggested that the chromone containing substituted pyrazole scaffold could be further optimized to explore novel, high-bioactivity nematicidal leads. | Wei Li Jiuhui Li Hongfeng Shen Jiagao Cheng Zhong Li Xiaoyong Xu | 2018 | Chinese Chemical Letters2018，29，6： | 7 |
| 5 | Response of soil respiration to nitrogen addition in two subtropical forest types显示文摘Anthropogenic activities have increased nitrogen(N)deposition in terrestrial ecosystems,which directly and indirectly affects soil biogeochemical processes,including soil respiration.However,the effects of the increases in N availability on soil respiration are not fully understood.In this study,soil respiration was measured using an infrared gas analyzer system with soil chambers under four N treatments(0,5,15,and 30 g Nm^-2 year^-1 as control,low N(LN),moderate N(MN),and high N(HN),respectively)in camphor tree and slash pine forests in subtropical China.Results showed that soil respiration rates decreased by 37% in the camphor tree forest and 27% in the slash pine forest on average on an annual base,respectively,in the N-fertilized treatments when compared with the control.No significant differences were found in the soil respiration rate among the LN,MN,and HN treatments in both forest types as these fertilized plots reached an adequate N content zone.In addition,soil microbial biomass carbon(C)content and fine root biomass declined in N-treated plots compared to the control.Our results indicated that elevated N deposition might alter the tree growth pattern,C partitioning,and microbial activity,which further affect soil C sequestration by reducing soil respiration in subtropical forests of China. | Wende YAN Xiaoyong CHEN Yuanying PENG Fan ZHU Wei ZHEN Xuyuan ZHANG | 2020 | Pedosphere2020，30，4： | 6 |
| 6 | Graphite dust deposition in the HTR-10 steam generator显示文摘Graphite dust has an important effect on the safe operation of a high-temperature gas-cooled reactor(HTR).The present study analyzes temperature and flow field distributions in the HTR-10 steam generator.The temperature and flow field distributions are then used to study thermophoretic deposition and turbulent deposition.The results show that as the dust diameter increases,the thermophoretic deposition decreases,while the turbulent deposition first decreases and then increases.The thermophoretic deposition is higher at higher reactor powers,with turbulent deposition growing more rapidly at higher reactor power.For small particles,the thermophoretic deposition effect is greater than the turbulent deposition effect,while for large particles,the turbulent deposition effect is dominant. | Wei Peng Yanan Zhen Xiaoyong Yang Suyuan Yu | 2013 | Particuology2013，11，5： | 5 |
| 7 | Research Progress of Refractory High Entropy Alloys:A Review显示文摘Owing to superior comprehensive performance than conventional superalloys at high temperature,refractory high entropy alloy(RHEA)is becoming a promising candidate for the next generation high-temperature material.Herein,contemporary aspects of corresponding development of RHEAs are reviewed to discuss various factors affecting the organization structure and service performance.It mainly covers alloying system and strengthening mechanism,the preparation method,plastic deformation and the related mechanism,as well as microstructure control by heat treatment.Firstly,the alloy systems and strengthening mechanism are introduced.This is followed by different preparation methods and the comparison of strengths and shortcomings based on different RHEAs.Then,hot deformation behavior and plastic deformation under different loadings are analyzed.Based on this,the influence of heat treatment on microstructures prior to and after the deformation is further summarized.Finally,some important research areas to be carried out in future are pointed out.This review will give a deep understanding of the effects of different factors on the service performance and provide scientific guide in designing RHEAs with improved performance. | Xiaochang Xie Neng Li Wei Liu Shuai Huang Xiaoyong He Qiuying Yu Huaping Xiong Enhui Wang Xinmei Hou | 2022 | Chinese Journal of Mechanical Engineering2022，35，6： | 4 |
| 8 | Microstructure and properties of Ga-modified 0.7BiFeO_3-0.3BaTiO_3 solid solution显示文摘Binary solid solutions 0.7Bi (GaxFe1-x)O3-0.3BaTiO3 (x = 0, 0.025, 0.05, 0.1) ceramics were prepared by traditional ceramic process. All the ceramic samples showed single perovskite phase except the sam- ple with x = 0.1. The effects of gallium doping on microstructure, ferromagnetic, ferroelectric, dielectric properties and conductivity were investigated. The results indicated that Ga-dopant could improve the sintering ability of the solid solution when the Ga content x was below 0.05. When x was over 0.05, the sintering ability of the solid solution was weakened, and the phase structure of 0.7BiFeO3-0.3BaTiO3 solid solution changed from rhombohedral phase into tetragonal ferroelectric phase. The electrical resistivity increased with the Ga content increasing. Both ferroelectricity and ferromagnetism were observed in all the ceramic samples. With the Ga content increasing, the remanent magnetization Mr increased and the magnetic coercive field Hc decreased. However, the remanent polarization Pr fluctu- ated, increasing firstly and decreasing later. | LIU XiaoHui XU Zhuo QU ShaoBo WEI XiaoYong CHEN JiangLi | 2007 | Chinese Science Bulletin2007，52，20： | 4 |

| 10 | Intraocular lens implantation performed first to protect the posterior capsule in Morgagnian cataracts during phacoemulsification显示文摘This study evaluated the safety of a modified method to implant an intraocular lens (IOL) into the capsular bag immediately after capsulorhexis with a whole or partial nucleus to protect the posterior capsule (PC) during phacoemulsification in a series of 12 Morgagnian cataracts. For 3 cases of hypermature cataracts with smaller and rigid nuclei, after a complete capsulorhexis, an IOL was directly inserted into the capsular bag, which protected the PC during the subsequent phacoemulsification process in the iris plate. For the other 9 cases with larger and softer nuclei, after the nucleus was partially emulsified, the IOL was inserted into the bag. Even with an obvious surge for some cases, the surgeries were uneventful in all 12 cases, with no PC rent or vitreous loss. IOL implantation into the capsular bag with a whole or partial nucleus can provide effective protection for the PC for hypermature cataract during phacoemulsification. | Xia Hua Yongxiao Dong Ling Wang Zhiqing Li Jianying Du Wei Chi Xiaoyong Yuan | 2019 | International Journal of Ophthalmology(English edition)2019，12，7： | 4 |
| 11 | Ciliary defects caused by dysregulation of O-GlcNAc modification are associated with diabetic complications显示文摘Dear Editor Diabetes is a chronic metabolic disease that has become a major epidemic worldwide. High blood glucose is thought to be the primary cause of most devastating long-term complications of diabetes. In addition to strict glycemic control,a number of therapeutics have been used to slow down the progression of diabetic complications. However,a majority of current therapies for most diabetic complications have shown disappointing results in clinical trials.Because these complications arise from a number of pathological processes,targets for early interventions that could lead to effective treatments are largely unknown. | Fan Yu Song Guo Te Li Jie Ran Wei Zhao Dengwen Li Min Liu Xiumin Yan Xiaoyong Yang Xueliang Zhu Jun Zhou | 2019 | Cell Research2019，29，2： | 3 |
| 12 | Analysis of crystallographic orientation and morphology of microstructure during hot working for an alpha/beta titanium alloy显示文摘This work focuses on analysis of microstructure morphology and crystallographic orientation for Ti-17 alloy during hot working.The results show that alpha phase and beta phase influence each other and there is a coordinate deformation between them.The non-uniform deformation is observed under small deformation conditions.The observing area can be divided into small deformation zone(area L)and large deformation zone(area H).Both alpha and beta phases remain the initial morphology,and they have better capability of coordinate deformation in area L,while coordinate capability is weak in area H in which alpha phase is globularized.Correspondingly,the Burgers orientation relations are well preserved in area L,but the orientation relations are more or less destroyed in area H.Dynamic recovery is the main mechanism of beta phase evolution when height reduction is lower.By contrast,the continuous dynamic recrystallization(CDRX)of beta phase gradually dominates the deformation pattern as the deformation increases.An uniformly globularized alpha structure is obtained under large deformation condition.The unsynchronized rotation of alpha phase around<11-20>pole occurs during deformation,which leads to the uniform crystal structure inside the same alpha lamellae.This process is an important step of globularization of the lamellar structure. | Jianwei Xu Weidong Zeng Dadi Zhou Wei Chen Shengtong He Xiaoyong Zhang | 2020 | Journal of Materials Science & Technology2020，59，24： | 3 |
| 13 | The dynamic responses of lamellar and equiaxed nearβ-Ti alloys subjected to multi-pass cross rolling显示文摘This work gives a comparison on the microstructural characteristics,textural discrepancies,and twinning behaviors of lamellar and equiaxed nearβ-Ti alloys during multi-pass cross rolling with a rolling reduction of 20%,50%and 80%.The results showed that the restoration mechanism of the alloy inβphase is strongly dependent on theαmorphologies,and in comparison,strain path has weaker influences on the grain refinement of theβmatrix.Therefore,the texture intensities of bothαandβphases were weakened owing to the dynamic recrystallization(DRX)of the two phases in the equiaxed microstructure.While,with regard to the lamellar microstructure,dynamic recovery(DRV)of theβphase predominated,forming elongatedβsubgrains.Besides,theαandβmatrix in lamellar microstructures obeyed the Burgers orientation relationship,which was gradually broken down until the final reduction.Lastly,the{1101}twinning exhibits a strong size effect.With the continuous DRX ofαphases,theα-twinning is suppressed owing to progressive grain refinement.The activation ofβ-twinning,namely{332}?113?and{112}?111?,in nearβ-Ti alloys is heavily dependent on the deficientβ-stabilizing elements and the local stress concentration.These findings provide an effective way to obtain ultra-fine grain microstructures of this alloy. | Wei Chen Hande Wang Y.C.Lin Xiaoyong Zhang Chao Chen Yaping Lv Kechao Zhou | 2020 | Journal of Materials Science & Technology2020，36，8： | 3 |
| 14 | Electron-phonon coupling-assisted universal red luminescence of o-phenylenediamine-based carbon dots显示文摘Due to the complex core-shell structure and variety of surface functional groups,the photoluminescence(PL)mechanism of carbon dots(CDs)remain unclear.o-Phenylenediamine(oPD),as one of the most common precursors for preparing red emissive CDs,has been extensively studied.Interestingly,most of the red emission CDs based on oPD have similar PL emission characteristics.Herein,we prepared six different oPD-based CDs and found that they had almost the same PL emission and absorption spectra after purifiication.Structural and spectral characterization indicated that they had similar carbon core structures but diffferent surface polymer shells.Furthermore,single-molecule PL spectroscopy confirmed that the multi-modal emission of those CDs originated from the transitions of different vibrational energy levels of the same PL center in the carbon core.In addition,the phenomenon of'spectral splitting'of single-particle CDs was observed at low temperature,which confirmed these oPD-based CDs were unique materials with properties of both organic molecules and quantum dots.Finally,theoretical calculations revealed their potential polymerization mode and carbon core structure.Moreover,we proposed the PL mechanism of red-emitting CDs based on oPD precursors;that is,the carbon core regulates the PL emission,and the polymer shell regulates the PL intensity.Our work resolves the controversy on the PL mechanism of oPD-based red CDs.These findings provide a general guide for the mechanism exploration and structural analysis of other types of CDs. | Boyang Wang Zhihong Wei Laizhi Sui Jingkun Yu Baowei Zhang Xiaoyong Wang Shengnan Feng Haoqiang Song Xue Yong Yuxi Tian Bai Yang Siyu Lu | 2022 | Light(Science & Applications)2022，11，7： | 2 |
| 15 | The 2-axis stress component decoupling of {100} c-Si by using oblique backscattering micro-Raman spectroscopy显示文摘With the application of strain engineering in microelectronics,complex stress states are introduced into advanced semiconductor devices.However,there is still a lack of effective metrology for the decoupling analysis of the complex stress states in semiconductor materials.This paper presents an investigation on the 2-axis stress component decoupling of{100}monocrystalline silicon(c-Si)by using oblique backscattering micro-Raman spectroscopy.A spectral-mechanical model was established,and two practicable methods for actual stress decoupling analyses were proposed.The verification experiments demonstrated the correctness and applicability of the methods proposed in this paper. | DongHui Fu XiaoYong He LuLu Ma HuaDan Xing Tian Meng Ying Chang Wei Qiu | 2020 | Science China(Physics,Mechanics & Astronomy)2020，63，9： | 2 |
| 16 | Geochronology, Geochemistry, and Sr–Nd–Hf Isotopes of the Balazha Ore-Bearing Porphyries: Implications for Petrogenesis and Geodynamic Setting of Late Cretaceous Magmatic Rocks in the Northern Lhasa Block, Tibet显示文摘The study of Late Cretaceous magmatic rocks, developed as a result of magmatism and related porphyry mineralization in the northern Lhasa block, is of significance for understanding the associated tectonic setting and mineralization. This paper reports zircon chronology, zircon Hf isotope data, wholerock Sr–Nd isotope data, and geochemistry data of Balazha porphyry ores in the northern Lhasa block. Geochemical features show that Balazha ore-bearing porphyries in the northern Lhasa block belong to high-Mg# adakitic rocks with a formation age of ~90 Ma; this is consistent with the Late Cretaceous magmatic activity that occurred at around 90 Ma in the region. The age of adakitic rocks is similar to the molybdenite Re–Os model age of the ore-bearing porphyries in the northern Lhasa block, indicating that the diagenesis and mineralization of both occurred during the same magmatism event in the Late Cretaceous. The Hf and Sr–Nd isotope data indicate that these magmatic rocks are the product of crust–mantle mixing. Differing proportions of materials involved in such an event form different types of medium-acid rocks, including ore-bearing porphyries. Based on regional studies, it has been proposed that Late Cretaceous magmatism and porphyry mineralization in the northern Lhasa block occurred during collision between the Lhasa and Qiangtang blocks. | LIU Wei WANG Baodi YANG Xiaoyong YUAN Sihua LIU Han LIAO Zhongli | 2018 | Acta Geologica Sinica(English Edition)2018，92，5： | 2 |
| 17 | One-step preparation of branched PEG functionalized AIE-active luminescent polymeric nanoprobes显示文摘The synthesis of amphiphilic aggregation-induced emission(AIE) dyes based organic nanoparticles has recently attracted increasing attention in the biomedical fields. These AIE dyes based nanoparticles could effectively overcome the aggregation caused quenching effect of conventional organic dyes, making them promising candidates for fabrication of ultrabright organic luminescent nanomaterials. In this work, AIE-active luminescent polymeric nanoparticles(4-NH_2-PEG-TPE-E LPNs) were facilely fabricated through Michael addition reaction between tetraphenylethene acrylate(TPE-E) and 4-arm-poly(ethylene glycol)-amine(4-NH_2-PEG) in rather mild ambient. The 4-NH_2-PEG can not only endow these AIE-active LPNs good water dispersibility, but also provide functional groups for further conjugation reaction. The size, morphology and luminescent properties of 4-NH_2-PEG-TPE-E LPNs were characterized by a series of techniques in detail. Results suggested that these AIE-active LPNs showed spherical morphology with diameter about 100–200 nm. The obtained 4-NH_2-PEG-TPE-E LPNs display high water dispersibility and strong fluorescence intensity because of their self assembly and AIE properties of TPE-E.Biological evaluation results demonstrated that 4-NH_2-PEG-TPE-E LPNs showed negative toxicity toward cancer cells and good fluorescent imaging performance. All of these features make 4-NH_2-PEG-TPE-E LPNs promising candidates for biological imaging and therapeutic applications. | Jun Chu Qiulan Lv Chunliang Guo Dazhuang Xu Ke Wang Meiying Liu Hongye Huang Xiaoyong Zhang Yen Wei | 2016 | Science China Chemistry2016，59，8： | 2 |
| 18 | Trends of sea surface wind energy over the South China Sea显示文摘Studies on climate change typically consider temperature and precipitation over extended periods but less so the wind. We used the Cross-Calibrated Multi-Platform (CCMP) 24-year wind fi eld data set to investigate the trends of wind energy over the South China Sea during 1988-2011. The results reveal a clear trend of increase in wind power density for each of three base statistics (i.e., mean, 90 th percentile and 99 th percentile) in all seasons and for annual means. The trends of wind power density showed obvious temporal and spatial variations. The magnitude of the trends was greatest in winter, intermediate in spring, and smallest in summer and autumn. A greater trend of increase was found in the northern areas of the South China Sea than in southern parts. The magnitude of the annual and seasonal trends over the South China Sea was larger in extreme high events (i.e., 90 th and 99 th percentiles) compared to the mean conditions. Sea surface temperature showed a negative correlation with the variability of wind power density over the majority of the South China Sea in all seasons and annual means, except for winter (41.7%). | JIANG Bo WEI Yongliang DING Jie ZHANG Rong LIU Yuxin WANG Xiaoyong FANG Yizhou | 2019 | Journal of Oceanology and Limnology2019，37，5： | 2 |
| 19 | Enhanced treatment for cerebral ischemia-reperfusion injury of puerarin loading liposomes through neutrophils-mediated targeted delivery显示文摘The recovery of blood circulation following cerebral infarction-associated thrombolysis brings new damage to the brain,which is cerebral ischemia-reperfusion injury(CIRI).Inflammation is the main pathological mechanism of CIRI.The inflammatory response triggered by cerebral ischemia-reperfusion provides neutrophils with a special opportunity to facilitate drug delivery to the site of ischemic penumbra through the chemotaxis of inflammatory factors by neutrophils.Puerarin is an isoflavone derivative with a significant neuroprotective effect in vitro.But the blood-brain barrier(BBB)impedes its therapeutic efficacy on CIRI within the brain.Inspired by the pathological process,we have used neutrophils as carriers to enhance the BBB penetration of liposomes loaded with puerarin and improve the concentration of puerarin in the brain parenchyma in this study.These results showed that puerarin-containing liposomes were released in response to inflammatory conditions associated with brain injury to enhance the neuroprotection effect at the ischemic penumbra. | Wei Liu Haowei Lu Xiaoyong Rao Xiang Li Hongdan Lu Feifei Li Yan He Riyue Yu Rongsheng Zhong Yao Zhang Xiaojian Luo Hongliang Xin | 2021 | Nano Research2021，14，12： | 2 |
