| 1 | Cytological mechanisms of interspecific incrossability and hybrid sterility between Oryza sativa L. and O. alta Swallen显示文摘Oryza sativa and O. alta belong to AA and CCDD genomes in Oryza, respectively. Interspecific repro-ductive isolation limits the transfer of favorable genes from O. alta into O. sativa. The cytological mechanisms of interspecific incrossability and hybrid sterility between O. sativa and O. alta were studied systematically in this paper. We indentified two cytological causes of interspecific incrossabil-ity. First, we observed embryo sac incompatibility that caused fertilization barriers of variable severity such as non-fertilization, fertilization stagnation and egg cell single-fertilization. Second, we observed hybrid inviability, the major cause for incrossability, apparent from hybrid embryo developmental stagnation and embryo abortion. Hybrid sterility included both embryo sac sterility and pollen sterility. The hybrid embryo sac was completely sterile and exhibited mainly embryo sac degeneration. Hybrid pollen was also sterile and mainly typical abortive. Hybrid sterility was mainly caused by severely ab-normal meioses of megasporocytes and pollen mother cells; it is the most important abnormality, being chromosome sterility. Several methods are suggested to overcome the interspecific reproductive iso-lation between O. sativa and O. alta. | FU XueLin LU YongGen LIU XiangDong Li JinQuan Feng JiuHuan | 2007 | Chinese Science Bulletin2007，52，6： | 11 |
| 2 | The Cenozoic activities of Yangjiang-Yitongdong Fault: insights from analysis of the tectonic characteristics and evolution processes in western Zhujiang(Pearl) River Mouth Basin显示文摘The Yangjiang-Yitongdong Fault (YJF) is an important NW-trending regional fault, which divides the Zhujiang (Pearl) River Mouth Basin (ZRMB) into western and eastern segments. In Cenozoic, the northern continental margin of the South China Sea (SCS) underwent continental rifting, breakup, seafloor spreading and thermal subsidence processes, and the Cenozoic activities of YJF is one part of this series of complex processes. Two long NW-trending multichannel seismic profiles located on both sides of the YJF extending from the continental shelf to Continent-Ocean Boundary (COB) were used to study the tectonic and sedimentary characteristics of western ZRMB. Using the 2D-Move software and back-stripping method, we constructed the balance cross-section model and calculated the fault activity rate. Through the comprehensive consideration of tectonic position, tectonic evolution history, featured structure, and stress analysis, we deduced the activity history of the YJF in Cenozoic. The results showed that the YJF can be divided into two segments by the central uplift belt. From 65 Ma to 32 Ma, the YJF was in sinistral motion as a whole, inherited the preexisting sinistral motion of Mesozoic YJF, in which, the southern part of YJF was mainly in extension activity, controlling the formation and evolution of Yunkai Low Uplift, coupled with slight sinistral motion. From 32 Ma to 23.8 Ma, the sinistral motion in northern part of YJF continued, while the sinistral motion in southern part began to stop or shifted to a slightly dextral motion. After 23.8 Ma, the dextral motion in southern part of YJF continued, while the sinistral motion in northern part of YJF gradually stopped, or shifted to the slightly dextral motion. The shift of the YJF strike-slip direction may be related to the magmatic underplating in continent-ocean transition, southeastern ZRMB. According to the analysis of tectonic activity intensity and rift sedimentary structure, the activities of YJF in Cenozoic played a regulating role in the rift extension process of ZRMB. | Yuhan Li Rongwei Zhu Hailing Liu Xuelin Qiu Haibo Huang | 2019 | Acta Oceanologica Sinica2019，38，9： | 10 |
| 3 | Passive seismic experiment and ScS wave splitting in the southwestern subbasin of South China Sea显示文摘The seismic experiment of 3D array of OBS in the southwestern sub-basin of the South China Sea(SCS) is briefly introduced in this paper.The data analysis of broadband OBS shows that totally 93 earthquakes with magnitude of Ms 6.0-6.9 and 10 earthquakes with magnitude above Ms 7.0 were recorded in high quality during this experiment,especially the catastrophic earthquake Ms 9.0 occurred in the east sea area of Japan on March 11,2011.The anisotropy parameters inversion of ScS wave of four events above Ms 7.0 indicates that the fast direction of shear wave is N58°E parallel to the ceased spreading ridge of the southwestern sub-basin of SCS(the slow direction is S35°E perpendicular to the spreading ridge),which means the spreading ridge is under compressing stress at present and the cessation of seafloor spreading is related to such stress field as well. | RUAN AiGuo LI JiaBiao LEE ChaoShing QIU XueLin PAN ShaoJun | 2012 | Chinese Science Bulletin2012，57，25： | 9 |
| 4 | Crust and Upper Mantle Electrical Resistivity Structure in the Panxi Region of the Eastern Tibetan Plateau and Its Significance显示文摘The Panxi region is located in the frontal zone of positive squeezing subduction and side squeezing shearing between the Indian plate and the Eurasian plate. The long-period magnetotelluric(LMT) and broadband magnetotelluric(MT) techniques are both used to study the deep electrical conductivity structure in this region; magnetic and gravity surveys are also performed along the profile. According to the 2-D resistivity model along the Yanyuan-Yongshan profile,a highconductivity layer(HCL) exists widely in the crust,and a high-resistivity block(HRB) exists widely in the upper mantle in general,as seen by the fact that a large HCL exists from the western Jinpingshan tectonic zone to the eastern Mabian tectonic zone in the crust,while the HRB found in the Panxi tectonic zone is of abnormally high resistivity in that background compared to both sides of Panxi tectonic zone. In addition,the gravity and magnetic field anomalies are of high value. Combined with geological data,the results indicate that there probably exists basic or ultrabasic rock with a large thickness in the lithosphere in the Panxi axial region,which indicates that fracture activity once occurred in the lithosphere. As a result,we can infer that the high-resistivity zone in the Panxi lithosphere is the eruption channel for Permian Emeishan basalt and the accumulation channel for basic and ultrabasic rock. The seismic sources along the profile are counted according to seismic record data. The results indicate that the most violent earthquake sources are located at the binding site of the HRB and the HCL,where the tectonic activity zone is generally acknowledged to be; however,the earthquakes occurring in the HCL are not so violent,which reflects the fact that the HCL is a plastic layer,and the fracture threshold of a plastic layer is low generally,making high stress difficult to accumulate but easy to release in the layer. As a result,a higher number of smaller earthquakes occurred in the HCL at Daliangshan tectonic zone,and violent earthquakes occurred at the binding site of high- and low-resistivity blocks at the Panxi tectonic zone. | ZHANG Gang WANG Xuben FANG Hui GUO Ziming ZHANG Zhaobin LUO Wei CAI Xuelin LI Jun LI Zhong WU Xing | 2015 | Acta Geologica Sinica(English Edition)2015，89，2： | 9 |
| 5 | Evaluating the reliability of microsatellite genotyping from low-quality DNA templates with a polynomial distribution model显示文摘Molecular studies using trace DNA, such as from museum specimens, ancient or forensic samples and samples obtained noninvasively, often have a common problem of low quality of DNA templates. Amplification errors, such as allelic dropout and false allele, may arise during polymerase chain reaction (PCR) using such samples. A mathematical model which treats homozygotes and heterozygotes discriminately has been developed to measure sample quality and compute the confidence level of using multipletube approaches. We use plucked hair samples collected from 26 individual Sichuan snub-nosed monkeys (Rhinopithecus roxel- lana) to test the model. In this case, a confidence level of 99% can be achieved by three positive PCRs. If the sample quality is very poor and requires many PCR replicates, an alternative multiplestep genotyping method is recommended. This model enables researchers to optimize experimental protocols through pilot studies and obtain reliable genetic information using noninvasive sampling method. | HE Gangi HUANG Kang GUO SongTao JI WeiHong QI XiaoGuang REN Yi JIN XueLin LI BaoGuo | 2011 | Chinese Science Bulletin2011，56，24： | 8 |
| 6 | Crustal S-wave velocity structure across the northeastern South China Sea continental margin: implications for lithology and mantle exhumation显示文摘The northeastern margin of the South China Sea (SCS), developed from continental rifting and breakup, is usually thought of as a non-volcanic margin. However, post-spreading volcanism is massive and lower crustal high-velocity anomalies are widespread, which complicate the nature of the margin here. To better understand crustal seismic velocities, lithology, and geophysical properties, we present an S-wave velocity (VS) model and a VP/VS model for the northeastern margin by using an existing P-wave velocity (VP) model as the starting model for 2-D kinematic S-wave forward ray tracing. The Mesozoic sedimentary sequence has lower VP/VS ratios than the Cenozoic sequence;in between is a main interface of P-S conversion. Two isolated high-velocity zones (HVZ) are found in the lower crust of the continental slope, showing S-wave velocities of 4.0–4.2 km/s and VP/VS ratios of 1.73–1.78. These values indicate a mafic composition, most likely of amphibolite facies. Also, a VP/VS versus VP plot indicates a magnesium-rich gabbro facies from post-spreading mantle melting at temperatures higher than normal. A third high-velocity zone (VP : 7.0–7.8 km/s;VP/VS: 1.85–1.96), 70-km wide and 4-km thick in the continent-ocean transition zone, is most likely to be a consequence of serpentinization of upwelled upper mantle. Seismic velocity structures and also gravity anomalies indicate that mantle upwelling/ serpentinization could be the most severe in the northeasternmost continent-ocean boundary of the SCS. Empirical relationships between seismic velocity and degree of serpentinization suggest that serpentinite content decreases with depth, from 43% in the lower crust to 37% into the mantle. | WenAi Hou Chun-Feng Li XiaoLi Wan MingHui Zhao XueLin Qiu | 2019 | Earth and Planetary Physics2019，3，4： | 8 |
| 7 | Study on correlation between humic acid and selenium in Kaschin-Beck disease areas显示文摘The relationship between humic acid and selenium content was studied in this research. The results of calculation showed that there is more humic acid and less selenium in Kaschin-Beck disease areas in China. Fulvic acid in soil could increase selenium level in plants. The chemical bonding between humic acid and selenium was observed with an I.R. spectroscope. It was remarkable for the changes of absorption peak and frequency in 1100-1000 cm-1, 900-700 cm-1. | Zhang Xuelin, Ren Shufen, Li Wencheng,Wang Wensheng, Wang Jinda, Wang Wenjun,and Zhang Yuxiachangchun Institute of Geography,Chinese Academy of Sciences,Changchun,China | 1991 | Journal of Environmental Sciences1991，3，4： | 5 |
| 8 | Seismic phases from the Moho and its implication on the ultraslow spreading ridge显示文摘The Moho interface provides critical evidence for crustal thickness and the mode of oceanic crust accretion.The seismic Moho interface has not been identified yet at the magma-rich segments(46°–52°E)of the ultraslow spreading Southwestern Indian Ridge(SWIR).This paper firstly deduces the characteristics and domains of seismic phases based on a theoretical oceanic crust model.Then,topographic correction is carried out for the OBS record sections along Profile Y3Y4 using the latest OBS data acquired from the detailed 3D seismic survey at the SWIR in 2010.Seismic phases are identified and analyzed,especially for the reflected and refracted seismic phases from the Moho.A 2D crustal model is finally established using the ray tracing and travel-time simulation method.The presence of reflected seismic phases at Segment 28 shows that the crustal rocks have been separated from the mantle by cooling and the Moho interface has already formed at zero age.The 2D seismic velocity structure across the axis of Segment 28 indicates that detachment faults play a key role during the processes of asymmetric oceanic crust accretion. | ZHANG Jiazheng ZHAO Minghui QIU Xuelin LI Jiabiao RUAN Aiguo | 2013 | Acta Oceanologica Sinica2013，32，12： | 5 |
| 9 | Comparison of Compositions and Structural Characterizations of Synthetic Nano-hydroxyapatite and Mineral Phase from Porcine Femoral Bone显示文摘In the paper, nano-hydroxyapatite was synthesized by hydrothermal treatment. The crystal morphology and compositions of the synthetic HA were investigated using TEM, IR, XRD and XPS techniques and were compared with those of porcine femoral bone apatite. The results showed that the synthetic HA is nanometer rod crystal similar to the bone apatite, and the average crystal sizes calculated by Scherrer equation for the four samples (HA dried at 80℃, unburned bone apatite, HA calcined at 750℃ and bone apatite calcined at 750℃) are 20.6, 21.7, 22.5 and 27.6nm, respectively. Moreover, the essential compositions for the synthetic HA and bone apatite are almost the same. | 张利 LI Yubao WANG Xuejiang Peng Xuelin Zuo Yi Han Jimei | 2004 | High Technology Letters2004，10，4： | 4 |

| 11 | Circuit model based design and analysis for a four-structure-switchable wireless power transfer system显示文摘The four-coil wireless power transfer(WPT)technology can effectively improve the transfer efficiency.The high efficiency,however,cannot be obtained along the whole transfer distance due to the phenomenon of frequency splitting in the over coupled region.Aiming at this limitation,this paper presents a switchable WPT system to improve the overall efficiency by changing the number of working coils.The switching conditions for the designed system are determined based on the analysis of the transfer efficiencies of four structures,which is deduced through modeling the equivalent circuits.The simulation results well comply with the experimental results and both of them indicate that the switchable system can greatly improve the overall transfer efficiency along the whole transfer distance.The overall efficiency of the experimental system can reach above 70%at9.97 MHz without additional complexity,which is higher than any single structure system. | FANG XueLin LIU Hao LI GuiYang SHAO Qi LI HongYi | 2015 | Science China(Technological Sciences)2015，58，3： | 3 |
| 12 | Construction of Rat Model of Hepatic Fibrosis with Blood Stasis Syndrome Integrated with Traditional Chinese Medicine(TCM)Syndrome and Western Medicine Disease显示文摘[Objective]According to the theory of blood stasis in traditional Chinese medicine( TCM),the animal modeling method of hepatic fibrosis integrated with pathology and symptoms was explored and improved,to construct a new type of rat model of hepatic fibrosis with blood stasis syndrome integrated with traditional Chinese and western medicine. [Method]The hepatic fibrosis model of blood stasis with blood stasis syndrome was constructed by jointing multi factors,including intragastric administration of ethanol,high fat and low protein feeding,joint injection of dimethylnitrosamine( DMN),bovine serum albumin( BSA) and norepinephrine( NE). The modeling method was further compared with traditional CC14 single-factor modeling method from the aspects of mortality,blood stasis syndrome of TCM,syndrome grading,general morphology of liver pathology,liver function changes,as well as expression levels of three kinds of collagen( type I and type III collagen,α-SMA) determined by immunohistochemical staining method,and four items of rat hepatic fibrosis( HA,P3 NP,LN,CⅣ content) determined by radio enzyme immunoassay. [Result]In blood stasis group,(1) the mortality of rats was 20%;(2) model rats appeared typical blood stasis syndromes of TCM such as ecchymosis,dark purple tongue,loose stool,and blood stasis syndrome grading was high;(3) fibrosis changes of liver such as dark white surface,dense gray nodules and brittle texture were observed in general morphological examination;(4) serological liver function tests found that ALT and AST of model rats,as well as TBIL,DBIL and IBIL contents increased significantly;(5) immunohistochemical staining demonstrated that the expression levels of three kinds of collagen(type I and type III collagen,α-SMA) increased significantly;(6) four items of rat serum hepatic fibrosis,HA,P3 NP,LN,CⅣ content,increased significantly;(7) the above results in blood stasis syndrome model group(except morality and liver function) were higher than those in CC14 modeling group,and the difference was statistically significant( P < 0. 05). [Conclusion]The new improved modeling method effectively reduces high mortality in traditional CC14 modeling method.In addition to low mortality,the model animal has dual characteristics of disease in western medicine and syndrome in TCM. It is consistent with the pathological characteristics of hepatic fibrosis in western medicine when according with the basic characteristics of blood stasis syndrome in TCM. | Peng Yue Duan Xuelin Zhao Tiejian Yao Le Wei Yanfei Li Guiyu | 2017 | Animal Husbandry and Feed Science2017，9，2： | 3 |
| 13 | Effects of Aqueous Extract of Plumbago zeylanica L. in the Reversal of DMN-induced Hepatic Fibrosis in Rat显示文摘[Objectives] This study was conducted to evaluate the action of the aqueous extract of a medicinal plant Plumbago zeylanica L. in the reversal of dimethylnitrosamine( DMN)-induced hepatic fibrosis in rats,and to provide a scientific basis for the utilization of P. zeylanica in treatment of hepatic fibrosis. [Methods] Hepatic fibrosis in rats was induced by intraperitoneal injection of DMN. The rats were then given the aqueous extract of P. zeylanica at high,medium or low concentration by gavage for five weeks. Serum level of alanine aminotransferase( ALT) was determined by lactate dehydrogenase( LDH)-release assay,and serum level of aspartate transaminase( AST) was measured by UV-malate dehydrogenase( MDH) assay. Serum levels of total bilirubin( TBIL),direct bilirubin( DBIL)and indirect bilirubin( IBIL) were measured by vanadate oxidation assay. Four indices of hepatic fibrosis( hyaluronic acid,laminin,procollagen type Ⅲ and collagen type IV) were determined by radioimmunoassay( RIA) assay. Morphological damage of liver tissue was observed by hematoxylin-eosin staining( H&E staining). Immunohistochemical staining was performed to determine the location and area of deposited collagen type I,collagen type Ⅲ and α-smooth muscle actin( α-SMA) in liver tissue. [Results]Compared with the negative control( rats with diseased liver and untreated with P. zeylanica aqueous extract),the serum levels of ALT,AST,TBIL,DBIL and IBIL were significantly decreased by P. zeylanica aqueous extract; the levels of the four serum indices of hepatic fibrosis were also obviously reduced. H&E staining showed that hepatic fibrosis in rats was obviously inhibited or even reversed by P. zeylanica aqueous extract. Immunohistochemical staining proved that the aqueous extract of P. zeylanica significantly reduced the area and coloration of collagen type I,collagen type Ⅲ and α-SMA in rat liver. [Conclusions] The aqueous extract of P. zeylanica has a definite effect in reversal of DMN-induced hepatic fibrosis in rat by promoting the recovery of liver function,reversal of histopathological changes and reducing fibrotic collagen. | Yue PENG Xuelin DUAN Tiejian ZHAO Yanfei WEI Guiyu LI Lulu LIU | 2017 | Agricultural Biotechnology2017，6，3： | 3 |
| 14 | In-situ growth of MAX phase coatings on carbonised wood and their terahertz shielding properties显示文摘Electromagnetic interference(EMI)shielding materials have received considerable attention in recent years.The EMI shielding effectiveness(SE)of materials depends on not only their composition but also their microstructures.Among various microstructure prototypes,porous structures provide the advantages of low density and high terahertz wave absorption.In this study,by using carbonised wood(CW)as a template,1-mm-thick MAX@CW composites(Ti2AlC@CW,V2A1C@CW,and Cr2AlC@CW)with a porous structure were fabricated through the molten salt method.The MAX@CW composites led to the formation of a conductive network and multilayer interface,which resulted in improved EMI SE.The average EMI SE values of the three MAX@CW composites were>45 dB in the frequency of 0.6-1.6 THz.Among the composites,V2A1C@CW exhibited the highest average EMI SE of 55 dB. | Jiaxuan HUANG Hujie WAN Mian LI Yiming ZHANG Jianfeng ZHU Xuelin LI Wenchao SHUI Yao LI Xiaomeng FAN Qiye WEN Xu XIAO Qing HUANG | 2021 | Journal of Advanced Ceramics2021，10，6： | 2 |

| 16 | Gene expression profiling under different photoperiod/temperature conditions in a photoperiod-/thermo-sensitive genic male sterile line of rice(Oryza sativa L.)显示文摘Peiai 64S is a photoperiod- and thermo- sensitive genic male sterile (PTSGMS) line of rice, which is male sterile at long day/high temperature and partial fertile at short day/low temperature. A cDNA array representing 3328 unique rice genes was used to profile the gene expression patterns in the young panicles of Peiai 64S under these two condi- tions. The statistical data showed that up to 14.60% of genes exhibited up-or down-regulated expressions in the plants at long day/high temperature compared with plants at short day/low temperature. Only four genes were up-regulated while 482 genes down-regulated. Real-time PCR with all the up-regulated and 9 randomly selected down-regulated genes confirmed the differential expressions detected by the array, indicating that the constructed cDNA array is reliable. These differently expressed genes participated in almost all cell biological responses. Analysis of up- and down-regulated genes revealed distinctive changes between the mRNA abundances of MMK1 and MMK2, both of which are analogs ofMAPK, and significant down-regulation of several transcription factors. It was suggested that changes that occurred in the MAPK signal transduction path- way might disturb the transcription control necessary for morphogenesis of pollens and corresponding phys- iological functions. | GUO Xiaoqin DONG Haitao ZHENG Kangle LUO Hongmei TAN Xuelin FANG Yongqi WANG Yanqin DENG Ye DAI Chengen LOU Yichun SHAO Jing SHI Wenqin ZHAO Dong LI Debao | 2006 | Chinese Science Bulletin2006，51，2： | 2 |
| 17 | Musk secretion in muskrats(Ondatra zibethicus L.):association with lipid and cholesterol metabolism-related pathways显示文摘Male muskrats(Ondatra zibethicus L.)secrete musk from their scent glands during musk secretion season.Musk plays an important role as a communication pheromone during the breeding season.In this study,gas chromatography–mass spectrometry(GC–MS)was used to analyze the main components of musk.The GC–MS results after methyl esterification showed that 71.55%of the musk is composed of fatty acids.The other components of muskrat musk include cholesterol(9.31%)and other organics.Transcriptome comparison between musk secretion and non-secretion seasons showed significant changes in the scent glands for 53 genes involved in fatty acid and cholesterol synthesis and metabolism regulatory pathways,which include fatty acid biosynthesis,elongation,and metabolism;steroid biosynthesis;steroid hormone biosynthesis pathways.A reverse transcription–polymerase chain reaction analysis confirmed these detected changes.Overall,our results indicated that lipid synthesis and metabolism play important roles in musk compound synthesis by providing energy for musk production,and the produced musk provides a mechanism for male muskrats to communicate with females during the breeding season. | TIANXIANG ZHANG MEISHAN ZHANG MINGHUI SHI WEIJIANG JIN SHUMIAO ZHANG MENGYUAN FAN YIMENG LI YUPING MENG XUELIN TIAN SHUQIANG LIU DEFU HU | 2021 | BIOCELL2021，45，2： | 2 |
| 18 | The source and transport of bioaerosols in the air:A review显示文摘Recent pandemic outbreak of the corona-virus disease 2019(COVID-19)has raised widespread concerns about the importance of the bioaerosols.They are atmospheric aerosol particles of biological origins,mainly including bacteria,fungi,viruses,pollen,and cell debris.Bioaerosols can exert a substantial impact on ecosystems,climate change,air quality,and public health.Here,we review several relevant topics on bioaerosols,including sampling and detection techniques,characterization,effects on health and air quality,and control methods.However,very few studies have focused on the source apportionment and transport of bioaerosols.The knowledge of the sources and transport pathways of bioaerosols is essential for a comprehensive understanding of the role microorganisms play in the atmosphere and control the spread of epidemic diseases associated with them.Therefore,this review comprehensively summarizes the up to date progress on the source characteristics,source identification,and diffusion and transport process of bioaerosols.We intercompare three types of diffusion and transport models,with a special emphasis on a widely used mathematical model.This review also highlights the main factors affecting the source emission and transport process,such as biogeographic regions,land-use types,and environmental factors.Finally,this review outlines future perspectives on bioaerosols. | Wenwen Xie Yanpeng Li Wenyan Bai Junli Hou Tianfeng Ma Xuelin Zeng Liyuan Zhang Taicheng An | 2021 | Frontiers of Environmental Science & Engineering2021，15，3： | 2 |
| 19 | Effect of austenite grain size and accelerated cooling start temperature on the transformation behaviors of multi-phase steel显示文摘The transformation behaviors and microstructures of a low carbon multi-phase steel were investigated by the simulation of deformation-relaxation-accelerated cooling processing,using a Gleeble 3500 thermal-mechanical simulator.A pre-treatment of solid solution at 1200°C was implemented to minimize the influence on transformation from solid solution/precipitation qualities of 0.08%Nb in this steel.On this basis,the effect of austenite grain size and accelerated cooling start temperature were studied individually.The results indicated that the transformation of ferrite in multi-phase steel could be significantly promoted by the refinement of austenite grains and the increase of relaxation time,while the hard phase,such as lath bainite or martensite,could still be obtained with the following accelerated cooling.In contrast,more uniform lower temperature transformed microstructure could form from coarse grain austenite.The potential benefit of austenite grain size on adjusting the proportion of phases in multiphase steel was also discussed. | LI XiuCheng XIA DianXiu WANG XueLin WANG XueMin SHANG ChengJia | 2013 | Science China(Technological Sciences)2013，56，1： | 2 |
| 20 | In situ formation of ionically conductive nanointerphase on Si particles for stable battery anode显示文摘Silicon(Si)is a promising anode candidate for next-generation lithium-ion batteries(LIBs)due to its high theoretical capacity.Solar Si photovoltaic waste possesses good purity and high output.Using it as the raw material for battery anodes can synchronously solve the problem of solid waste pollution and enable high energy density LIBs.A critical issue impeding the practical application of Si is the undesirable side reactions at the electrolyte-particle interface and the resulting increase in impedance during cycling.Herein,a Si-P core shell structure with chemical bonding at the Si-P interface is fabricated through a simple mechanical alloying reaction between red P and solar Si photovoltaic waste.The P nanoshell with thickness within 15 nm converts to Li3P during the initial lithiation process and maintains its phase on cycling.The as-formed Li3P nanolayer functions as a stable,ionically conductive protective layer that reduces the direct contact between Si and electrolytes,and thus suppresses undesired side reactions.The Si-P nanocomposite exhibits stable electrochemical cycling with a high reversible capacity of 1,178 mAh g^(−1)after 500 cycles at 1,200 mA g^(−1),as well as excellent rate capability(912 mAh g^(−1)at 2 C).With 15 wt%addition to graphite,a graphite/Si-P hybrid electrode shows a high overall reversible specific capacity of 447 mAh g^(−1)and 88.3%capacity retention after 100 cycles at high areal capacity of 2.64 mAh cm^(−2) at 100 mA g^(−1),indicating its promise as a drop-in anode in practical LIBs. | Xiaoxue Chen Gaofeng Ge Wenyu Wang Bao Zhang Jianjun Jiang Xuelin Yang Yuzhang Li Li Wang Xiangming He Yongming Sun | 2021 | Science China Chemistry2021，64，8： | 2 |
