| 1 | Discrimination of abiogenic and biogenic alkane gases显示文摘We have combined the analytical data of the carbon isotope distribution pattern, R/Ra and CH4/3He values of abiogenic and biogenic (referring to the thermogenic and bacterial or microbial) alkane gases in China with those of alkane gases from USA, Russia, Germany, Australia and other countries. Four discrimination criteria are derived from this comparative study: 1) Carbon isotopic composition is generally greater than -30‰ for abiogenic methane and less than -30‰ for biogenic methane; 2) Abiogenic alkane gases have a carbon isotopic reversal trend (δ 13C1> δ 13C2> δ 13C3> δ 13C4) with δ 13C1>-30‰ in general; 3) Gases with R/Ra >0.5 and δ 13C11 δ 13C2>0 are of abiogenic origin; 4) Gases (meth- ane) with CH4/3He≤106 are of abiogenic origin, whereas gases with CH4/3He≥1011 are of biogenic origin. | DAI JinXing ZOU CaiNeng ZHANG ShuiChang LI Jian NI YunYan HU GuoYi LUO Xia TAO ShiZhen ZHU GuangYou MI JingKui LI ZhiSheng HU AnPing YANG Chun ZHOU QingHua SHUAI YanHua ZHANG Ying MA ChengHua | 2008 | Science China Earth Sciences2008，51，12： | 17 |
| 2 | Visible light-induced N-doped TiO_2 nanoparticles for the degradation of microcystin-LR显示文摘N-doped nano-crystalline TiO2 powders have been synthesized by the sol-gel method.The shape and crystal structure of the resulting N-doped TiO2 were investigated by X-ray Photoelectron Spectroscopy (XPS),X-ray spectroscopy (XRD),Transmission Electron Microscopy (TEM) and UV-vis reflection spectrum.The results showed that doping TiO2 with nitrogen can lower its band gap and apparently shift its optical response to the visible region.Under the visible light (λ> 420 nm) irradiation,the MC-LR was degraded by the synthesized N-TiO2 nano-material.The variation of MC-LR amount and its intermediates were detected by high performance liquid chromatography (HPLC) and LC-MS,respectively.The mineralization of MC-LR was determined by total organic carbon (TOC) analysis.Simultaneously,transient oxidative species generated during photocatalysis were tracked by electron spin resonance (ESR) and Peroxidase method.All these results indicated that visible-light excited N-TiO2 can activate molecular oxygen and thereby achieve degradation of MC-LR completely within 14 h.The removal of 59% of TOC was achieved after 20 h irradiation.The major oxidative species in the system were hydroxyl radical (·OH) and H2O2.13 Kinds of intermediates were primarily identified in the process.Based on these results,a reasonable conclusion was drawn for the degradation of MC-LR wherein its four positions are easy to be attacked by the photo-generated OH radical followed by the hydrolyzation of peptides. | YANG Jing,CHEN DengXia,DENG AnPing,FANG YanFen,LUO GuangFu,LI DeJiang,LI RuiPing & HUANG YingPing Alan G.MacDiarmid Research Institute of Renewable Energy,China Three Gorges University,Yichang 443000,China | 2010 | Science China Chemistry2010，53，8： | 12 |
| 3 | Geochemistry of the E-MORB type ophiolite and related volcanic rocks from the Wushan area, West Qinling显示文摘The mafic-ultramafic assemblages, which thrustthrust into the Wushan-Tangzang boundary fault as some blocks and outcropped in the Yuanyangzhen, Lijiahe, Lubangou and Gaojiahe area, consist mainly of meta-peridotites, gabbros and basalts. The meta-peridotites are characterized by high SiO2 and MgO contents, low ΣREE, as well as their chondrite-normalized rare earth element patterns show some similarities to that of middle oceanic meta-peridotite. The basalts from the Yuanyangzhen, Lijiahe and Lubangou area are characterized by relatively high TiO2 content, low Al2O3 content and Na2O>>K2O. Above all, it is the slight enrichment or flat REE distribution patterns and the unfractionated in HFS elements in the primitive-normalized trace elements distribution patterns that indicate these basalts are similar to that of the typical E-MORB. In comparison, the basalts from the Gaojiahe section are featured by depletion in Nb and Ta contents and enrichment in Th content which show that these were derived from an island-arc setting. From studies of the regional geology, petrology, geochemistry, geo- chronology and all above evidence, it can be suggested that the mafic-ultramafic rocks from the Wushan area are mainly dismembered E-MORB type ophiolite, which represent the fragments of the lithosphere of the Early-Paleozoic Qinling ocean. It is preferred that these rocks were formed in an initial mid-ocean ridge setting during the beginning stage of the oceanic basin spreading. This ophiolite together with the Gaojiahe island-arc basalts shows that there exists an ophiolitic mélange along the Wushan-Tangzang boundary fault, and marks the suture zone after the closure of the Qinling ocean in early Paleozoic. | DONG YunPeng ZHANG GuoWei YANG Zhao ZHAO Xia MA HaiYong YAO AnPing | 2007 | Science China Earth Sciences2007，50，z2： | 9 |
| 4 | Recent progress of nanogenerators acting as biomedical sensors in vivo显示文摘Since the nanogenerator(NG) was invented in 2006, it has been successfully developed and utilized to harvest various forms of mechanical energy in vivo. The NGs promote the progress of self-powered biomedical devices. Moreover, NGs can also be used as sensors to detect a variety of important physiological signals, which brings us closer to real-time, high-fidelity monitoring of physical and pathological information. This paper summarizes the in vivo applications of NGs as biomedical sensors, including in cardiac sensors, respiration sensors, blood pressure sensors, gastrointestinal sensors and bladder sensors.However, there are still many challenges in using NGs as sensors in vivo. For example, how can we minimize and encapsulate the NGs, how can we increase the stability and reliability during long-term detection, and how can we establish a corresponding relationship between the NG’s electrical output and the physiological signals. It is also critical to follow the medical principles more closely in the development of self-powered sensors in the future. We believe that the self-powered sensors would promote the development of the next-generation healthcare monitoring systems. | Jinyan Sun Anping Yang Chaochao Zhao Fang Liu Zhou Li | 2019 | Science Bulletin2019，64，18： | 9 |
| 5 | Preliminary analysis of spatiotemporal pattern of global land surface water显示文摘Land surface water(LSW) is one of the most important resources for human survival and development, and it is also a main component of global water recycling. A full understanding of the spatial distribution of land surface water and a continuous measuring of its dynamics can support to diagnose the global ecosystem and environment. Based on the Global Land 30-water 2000 and Global Land 30-water 2010 products, this research analyzed the spatial distribution pattern and temporal fluctuation of land surface water under scale-levels of global, latitude and longitude, continents, and climate zones. The Global Land 30-water products were corrected the temporal inconsistency of original remotely sensed data using MODIS time-series data, and then calculated the indices such as water area, water ration and coefficient of spatial variation for further analysis. Results show that total water area of land surface is about 3.68 million km2(2010), and occupies 2.73% of land area. The spatial distribution of land surface water is extremely uneven and is gathered mainly in mid- to high-latitude area of the Northern Hemisphere and tropic area. The comparison of water ratio between 2000 and 2010 indicates the overall fluctuation is small but spatially differentiated. The Global Land 30-water products and the statistics provided the fundamental information for analyzing the spatial distribution pattern and temporal fluctuation of land surface water and diagnosing the global ecosystem and environment. | CAO Xin CHEN Jun CHEN LiJun LIAO AnPing SUN FangDi LI Yang LI Lei LIN ZhongHui PANG ZhiGuo CHEN Jin HE ChaoYing PENG Shu | 2014 | Science China Earth Sciences2014，57，10： | 8 |
| 6 | High density methane inclusions in Puguang Gasfield:Discovery and a T-P genetic study显示文摘Based on measurement of homogenization temperature of inclusions and Raman spectral analysis, high density methane inclusions were discovered in the Triassic reservoirs of Puguang Gasfield. The methane inclusions show a homogenization temperature Th = -117.5― -118.1℃, a corresponding density of 0.3455―0.3477 g/cm3, and a Raman scatter peak v1 shift varying between 2911―2910 cm-1, which signifies a very high density of methane inclusions. The salt water inclusions paragenetic with methane inclusions show a homogenization temperature Th=170―180℃. Based on the composition of methane inclusions as determined by Raman spectra, PVTsim software was used to simulate the trapping pressure for high density methane inclusions in geologic history, and the trapping pressure was found to be as high as 153―160 MPa. Even though Puguang Gasfield is currently a gas pool of normal pressure, and the fluid pressure for the gas pool ranges between 56―65 MPa. However, data from this study indicates that remarkable overpressure may be generated at the stage of mass production of gas cracked from oils in Cretaceous, as high density methane inclusions constitute key evidence for overpressure in gas pool in geologic history. Meanwhile, discovery of small amounts of H2S, CO2 or heavy hydrocarbon in part of the high density methane inclusions indicates that the geochemical environment for trapping of inclusions may be related to formation of H2S. Therefore, the observation results can help to explore the thermochemical sulfate reduction (TSR) conditions for oil cracking and H2S formation. | LIU Delian DAI JinXing XIAO XianMing TIAN Hui YANG Chun HU AnPing MI JingKui SONG ZhiGuang | 2009 | Chinese Science Bulletin2009，54，24： | 8 |
| 7 | Allele-defined genome reveals biallelic differentiation during cassava evolution显示文摘Dear Editor,Generation of heterozygous genomes by hybridization between or within species can help maintain plant diversity and serve as a potential source of new species(Baek et al.,2018).Moreover,genomic heterozygosity is associated with genomic coadaptation,developmental stability,and heterosis.Accurate definition of alleles in haplotypes is necessary to precisely characterize allelic variation controlling agriculturally important traits(Shi et al.,2019).Currently,most released genomes have mosaic assembly of haplotypes due to random selection or collapse of alleles during genome assembly(Shi et al.,2019),which masked allelic variation and functional differentiation of divergent alleles in heterozygous species. | Wei Hu Changmian Ji Haitao shi Zhe Liang Zehong Ding Jianqiu Ye Wenjun Ou Gang Zhou Weiwei Tie Yan Yan Jinghao Yang Xiaoying Yang Yunxie Wei Zhiqiang Jin Jianghui Xie Ming Peng Wenquan Wang Anping Guo Biyu Xu Jianchun Guo Songbi Chen Liming Ma Mingcheng Wang Yang Zhou Xiaolong Li Ruoxi Li Siyi Guo Xinhui Xiao Zhongqing Wan Feifei An Jie Zhang Qingyun Leng Yin Li Ray Ming Kaimian Li | 2021 | Molecular Plant2021，14，6： | 8 |
| 8 | Catalysis of organic pollutant photodegradation by metal phthalocyanines immobilized on TiO_2@SiO_2显示文摘A TiO2@SiO2 hybrid support was prepared by the sol-precipitation method using n-octylamine as a template.The photocatalyst manganese phthalocyanine tetrasulfonic acid (MnPcS) was immobilized on the support to form MnPcS-TiO2@SiO2.X-ray diffraction (XRD) and UV-Visible diffuse reflectance spectra (UV-Vis DRS) were employed to characterize the catalyst.The photocatalytic degradation of rhodamine B (RhB) and the catalytic oxidation of o-phenylenediamine (OPDA) under visible light irradiation were used as probe reactions.The mineralization efficiency and the degradation mechanism were evaluated using chemical oxygen demand (COD Cr) assays and electron spin resonance (ESR),respectively.RhB was efficiently degraded by immobilized MnPcS-TiO2@SiO2 under visible light irradiation.Complete decolorization of RhB occurred after 240 min of irradiation and 64.02% COD Cr removal occurred after 24 h of irradiation.ESR results indicated that the oxidation process was dominated by the hydroxyl radical (·OH) and superoxide radical (O-·2) generated in the system. | WANG ShuLian FANG YanFen YANG Yong LIU JunZi DENG AnPing ZHAO XiaoRong HUANG YingPing | 2011 | Chinese Science Bulletin2011，56，10： | 5 |
| 9 | Preparation and evaluation of bis(diallyl alkyl tertiary ammonium salt) polymer as a promising adsorbent for phosphorus removal显示文摘Problems associated with water eutrophication due to high phosphorus concentrations and related environmentally safe solutions have attracted wide attention.A novel bis(diallyl alkyl tertiary ammonium salt)polymer,particularly poly(N1,N1,N6,N6-tetraallylhexane-1,6-diammonium dichloride)(PTAHDADC),was synthesized and characterized by Fourier transform infrared spectroscopy,nuclear magnetic resonance,scanning electron microscopy,mercury intrusion method,and thermogravimetric analysis.The adsorption characteristics in phosphorus were evaluated in dilute solution,and the recycling properties of PTAHDADC were investigated.Results showed that PTAHDADC possessed macropores with a size distribution ranging from 30 to 130μm concentrating at 63μm in diameter and had 46.52%of porosity,excellent thermal stability below 530 K,and insolubility.PTAHDADC could effectively remove phosphorus at p H=7–11 and had a removal efficiency exceeding 98.4%at pH=10–11.The adsorption equilibrium data of PTAHDADC for phosphorus accorded well with the Langmuir and pseudo-second-order kinetic models.Maximum adsorption capacity was 52.82 mg/g at 293 K.PTAHDADC adsorbed phosphorus rapidly and reached equilibrium within 90 min.Calculated activation energy Eawas 15.18 k J/mol.PTAHDADC presented an excellent recyclability with only 8.23%loss of removal efficiency after five adsorption–desorption cycles.The morphology and structure of PTAHDADC slightly changed as evidenced by the pre-and post-adsorption of phosphorus,but the process was accompanied by the partial deprotonation of the(–CH2)3-NH+group of PTAHDADC.The adsorption was a spontaneous exothermic process driven by entropy through physisorption,electrostatic attraction,and ion exchange.Survey results showed that PTAHDADC was a highly efficient and fast-adsorbing phosphorus-removal material prospective in treating wastewater. | Zhengchi Yang Lihua Liu Lu Zhao Gang Su Zuoxiao Wei Anping Tang Jianrong Xue | 2019 | Journal of Environmental Sciences2019，31，12： | 3 |
| 10 | Comparing community birdwatching and professional bird monitoring with implications for avian diversity research: a case study of Suzhou, China显示文摘Background:In the past decades,birdwatching as a hobby developed rapidly and produced ample scientific records that have aided conservation efforts.Therefore,it is increasingly attractive to promote avian research by providing data from birdwatching.Methods:We compared records from 16 years of community birdwatching and a 1-year formalized bird monitoring in Suzhou,China to study the similarities and differences between the two monitoring methods.Results:We showed that within the 325 bird species recorded by the two methods,an annual average of 108 species were documented by community science and 223 bird species were recorded by 1-year formalized monitoring.Measured by the number of bird species recorded per survey trip,the bird monitoring activity of community birdwatchers was significantly lower.Furthermore,the monitoring intensity of community birdwatching measured as the average survey trips per site each survey year was also lower than that of formalized bird monitoring.In addition,community birdwatchers preferred urban landscapes to rural areas.Conclusions:Community birdwatching could record the majority of local birds and complements the professional surveys in avian research.Well designed and coordinated community science can be used to expand the knowledge about avian distribution and population dynamics.These findings are critical for the development of conservation science with regard to community involvement. | Yan Zhou Anping Chen Jenny QOuyang Yanlin Liu Aiyu Zheng Zaixi Yang Yong Zhang Bin Wang Yifei Jia Shengwu Jiao Qing Zeng Changhu Lu | 2020 | Avian Research2020，11，2： | 2 |

| 18 | Effects of V addition on the mechanical properties at elevated temperatures in a γ”-strengthened NiCoCr-based multi-component alloy显示文摘Ni Co Cr-based multi-component alloys have drawn much attention due to their exceptional ductility and strain hardening capacity.However,insufficient strength-ductility synergy of NiCoCr alloy has always been an issue that prevents it from extensive applications.According to our previous research,the precipitation ofγ”phase can significantly improve the strength-ductility synergy of this alloy system at room temperature.In this study,the effects of V addition onγ”phase stability and high-temperature mechanical properties have been explicitly investigated.The results indicate that V addition can stabilize the metastableγ”phase in this alloy system and prevent it from transforming into a stableδphase at grain boundaries upon 650℃aging,resulting in improved mechanical properties at elevated temperatures.The specific strength ofγ”-strengthened multi-component NiCoCr-based alloy can reach up to 86.2 MPa gcmat 650℃,which is higher than those of Ni-based superalloys,IN 939 and Waspaloy.This work provides theoretical guidance for the novel design of γ”-strengthened alloy for high-temperature applications. | Yunwei Pan Anping Dong Yang Zhou Dafan Du Donghong Wang Guoliang Zhu Baode Sun | 2022 | Journal of Materials Science & Technology2022，，12： | 0 |
