| 1 | Colorectal cancer burden and trends:Comparison between China and major burden countries in the world显示文摘Objective:To summarize the colorectal cancer(CRC)burden and trend in the world,and compare the difference of CRC burden between other countries and China.Methods:Incidence and mortality data were extracted from the GLOBOCAN2018 and Cancer Incidence in Five Continents.Age-specific incidence trend was conducted by Joinpoint analysis and average annual percent changes were calculated.Results:About 1.85 million new cases and 0.88 million deaths were expected in 2018 worldwide,including 0.52 million(28.20%)new cases and 0.25 million(28.11%)deaths in China.Hungary had the highest age-standardized incidence and mortality rates in the world,while for China,the incidence and mortality rates were only half of that.CRC incidence and mortality were highly correlated with human development index(HDI).Unlike the rapid increase in Republic of Korea and the downward trend in Canada and Australia,the age-standardized incidence rates by world standard population in China and Norway were rising gradually.The age-specific incidence rate in the age group of 50-59 years in China was increasing rapidly,while in Republic of Korea and Canada,the fastest growing age group was 30-39 years.Conclusions:The variations of CRC burden reflect the difference of risk factors,as well as levels of HDI and screening(early detection activities).The burden of CRC in China is high,and the incidence of CRC continues to increase,which may lead to a sustained increase in the burden of CRC in China in the future.Screening should be expanded to control CRC,and focused on young people in China. | Jiachen Zhou Rongshou Zheng Siwei Zhang Hongmei Zeng Shaoming Wang Ru Chen Kexin Sun Minjuan Li Jianhua Gu Guihua Zhuang Wenqiang Wei | 2021 | Chinese Journal of Cancer Research2021，33，1： | 16 |
| 2 | Adjuvant chemotherapy with paclitaxel and cisplatin in lymph node-positive thoracic esophageal squamous cell carcinoma显示文摘Objective:No standard postoperative adjuvant chemotherapy has ever been established in node-positive esophageal squamous cell carcinoma(ESCC).This is a study to explore the effect of postoperative paclitaxel(PTX)and cisplatin(DDP)in lymph node-positive,completely resected thoracic ESCC patients.Methods:We conducted a prospective phase II trial.Patients had pathologically node-positive thoracic ESCC with negative margins.Outcomes of disease-free survival(DFS)and overall survival(OS)were compared with a matched historical control cohort.The postoperative chemotherapy regimen consisted of 4 to 6 cycles of PTX 150mg/m2 administered intravenously on d 1 followed by DDP 50 mg/m2 on d 2 every 14 d.Results:Forty-three patients were accrued from December 2007 to May 2012 at Cancer Hospital of Chinese Academy of Medical Sciences for adjuvant chemotherapy.The historical control group consisted of 80 patients who received complete resection but no adjuvant chemotherapy during the same period of time.Of the 43 patients with adjuvant chemotherapy,37(86.0%)patients completed 4 to 6 cycles of chemotherapy.The 3-year DFS rates were56.3%in the adjuvant group and 34.6%in the control group(P=0.006).The 3-year OS rates were 55.0%in the adjuvant group and 37.5%in the control group(P=0.013).Multivariate analysis revealed that postoperative chemotherapy was the significant predictor for improved OS(P=0.005).Conclusions:Biweekly adjuvant PTX and DDP might improve 3-year DFS and OS in lymph node-positive,curatively resected thoracic ESCC patients.These conclusions warrant further study in randomized phase III clinical trials. | Liangze Zhang Weiwei Li Xiao Lyu Yan Song Yousheng Mao Shaoming Wang Jing Huang | 2017 | Chinese Journal of Cancer Research2017，29，2： | 15 |
| 3 | Cancer statistics in Chinese older people,2022:current burden,time trends,and comparisons with the US,Japan,and the Republic of Korea显示文摘Largely due to population ageing,the cancer burden from older people has been rising,which imposed considerable pressure on current Chinese healthcare system.We provide comprehensive information about cancer burden of Chinese older people based on the most recent data from National Central Cancer Registry of China.The logarithmic linear regression was used to project the current cancer burden in 2022,and Joinpoint regression was used for temporal trend analysis from 2000 to 2017.We also estimated cancer statistics of older people in the US,Japan and the Republic of Korea for comparisons.It is estimated that 2.79 million cases and 1.94 million deaths occur for Chinese older people,representing 55.8%and 68.2%of cases and deaths in all population in 2022.The overall cancer incidence rate gradually increased among older women,while the mortality rates declined for both sexes.Notably,approximately 10.0%of all cases and 17.7%of all deaths are from people aged over 80 years,and cancer incidence and mortality in this age group showed upward trends for women.Lung cancer and digestive cancers are the leading cancer types for Chinese older people.Compared with other countries,China has lower incidence rates but higher mortality rates for older people.The rapidly growing burden of prostate cancer,breast cancer,colorectal cancer,and declines in esophageal cancer,stomach cancer,and liver cancer among older people indicate the cancer pattern in China is being in a transition stage to that in developed countries.Our findings imply that it should be the national health priority to meet the growing demands for cancer diagnosis,treatment and care services from the older people as the rapid population ageing in next few decades. | Wen Ju Rongshou Zheng Siwei Zhang Hongmei Zeng Kexin Sun Shaoming Wang Ru Chen Li Li Wenqiang Wei Jie He | 2023 | Science China(Life Sciences)2023，66，5： | 15 |
| 4 | Performance of a completely autotrophic nitrogen removal over nitrite process for treating wastewater with different substrates at ambient temperature显示文摘The stability and parameters of a bio-ceramic filter for completely autotrophic nitrogen removal were investigated.The completely autotrophic nitrogen removal over nitrite(CANON) reactor was fed with different concentrations of ammonia(400,300,and 200mg N/L) but constant influent ammonia load.The results showed that the CANON system can achieve good treatment performance at ambient temperature(15-23°C).The average removal rate and removal loading of NH4+-N and TN was 83.90%,1.26kg N/(m3·day),and 70.14%,1.09kg N/(m3·day),respectively.Among the influencing factors like pH,dissolved oxygen and alkalinity,it was indicated that the pH was the key parameter of the performance of the CANON system.Observing the variation of pH would contribute to better control of the CANON system in an intuitive and fast way.Denaturing gradient gel electrophoresis analysis of microorganisms further revealed that there were some significant changes in the community structure of ammonium oxidizing bacteria,which had low diversity in different stages,while the species of anaerobic ammonium oxidizing(anammox) bacteria were fewer and the community composition was relatively stable.These observations showed that anaerobic ammonia oxidation was more stable than the aerobic ammonia oxidation,which could explain that why the CANON system maintained a good removal efficiency under the changing substrate conditions. | Xiaoyan Chang Dong Li Yuhai Liang Zhuo Yang Shaoming Cui Tao Liu Huiping Zeng Jie Zhang | 2013 | Journal of Environmental Sciences2013，25，4： | 12 |
| 5 | Advances in ultra-high temperature ceramics,composites,and coatings显示文摘Ultra-high temperature ceramics(UHTCs)are generally referred to the carbides,nitrides,and borides of the transition metals,with the Group IVB compounds(Zr&Hf)and TaC as the main focus.The UHTCs are endowed with ultra-high melting points,excellent mechanical properties,and ablation resistance at elevated temperatures.These unique combinations of properties make them promising materials for extremely environmental structural applications in rocket and hypersonic vehicles,particularly nozzles,leading edges,and engine components,etc.In addition to bulk UHTCs,UHTC coatings and fiber reinforced UHTC composites are extensively developed and applied to avoid the intrinsic brittleness and poor thermal shock resistance of bulk ceramics.Recently,high-entropy UHTCs are developed rapidly and attract a lot of attention as an emerging direction for ultra-high temperature materials.This review presents the state of the art of processing approaches,microstructure design and properties of UHTCs from bulk materials to composites and coatings,as well as the future directions. | Dewei NI Yuan CHENG Jiaping ZHANG Ji-Xuan LIU Ji ZOU Bowen CHEN Haoyang WU Hejun LI Shaoming DONG Jiecai HAN Xinghong ZHANG Qiangang FU Guo-Jun ZHANG | 2022 | Journal of Advanced Ceramics2022，11，1： | 9 |

The result shows that the temporal gravity changes basically reflect the current mass movement and occurrence of strong earthquakes. | Li Hui Shen Chongyang Sun Shaoan Wang Xiaoquan Xiang Aimin Liu Shaoming | 2011 | Geodesy and Geodynamics2011，2，1： | 7 |
| 7 | Advances in crop phenotyping and multi-environment trials显示文摘Efficient evaluation of crop phenotypes is a prerequisite for breeding, cultivar adoption, genomics and phenomics study. Plant genotyping is developing rapidly through the use of high-throughput sequencing techniques,while plant phenotyping has lagged far behind and it has become the rate-limiting factor in genetics, large-scale breeding and development of new cultivars. In this paper,we consider crop phenotyping technology under three categories. The first is high-throughput phenotyping techniques in controlled environments such as greenhouses or specifically designed platforms. The second is a phenotypic strengthening test in semi-controlled environments, especially for traits that are difficult to be tested in multi-environment trials(MET), such as lodging, drought and disease resistance. The third is MET in uncontrolled environments, in which crop plants are managed according to farmer's cultural practices. Research and application of these phenotyping techniques are reviewed and methods for MET improvement proposed. | Zhe LIU Fan ZHANG Qin MA Dong AN Lin LI Xiaodong ZHANG Dehai ZHU Shaoming LI | 2015 | Frontiers of Agricultural Science and Engineering2015，2，1： | 7 |
| 8 | Distribution of organic carbon in sediments and its influences on adjacent sea area in the turbidity maximum of Changjiang Estuary in China显示文摘Distributions and sources of total organic carbon(TOC)in seabed sediments and their implications for hydrodynamics are analyzed,in the turbidity maximum of the Changjiang Estuary.Ecology ecoenvironmental effects of estuary water on the continuously increasing terrigenous organic carbon from the Changjiang River are also explored through variations of organic carbon content and water quality indicators.Results show that,hydrodynamics exert important influences on distributions of organic carbon in the turbidity maximum of Changjiang Estuary.For their redistribution effect of terrigenous organic carbon within the moving layer in the whole region,variations from land to sea are not indicated by surficial and vertical average values of TOC and total nitrogen(TN)contents in core sediment,as well as organic stable carbon isotopes in surface sediments.However,on the long-time scale,the trend of terrigenous organic carbon decreasing from land to sea is still displayed by variations of stable carbon isotopic average values becoming heavier from land to sea.Previous studies have shown that high content of Chl a cannot appear in the Changjiang Estuary in despite of adequate nourishment supply,because photosynthesis of phytoplankton is constrained by high suspended sediment concentration(SSC).However,an area with a high content of Chl a occurs,which may be caused by resuspended benthic algae with bottom fine grain-size sediments.Tremendous pressures are imposed on the environment of Changjiang Estuary,because of ultrophication trends and special hydrodynamics.Phytoplankton bloom area tends to extend from the outer sea to the mouth of Changjiang River. | GAO Jianhua WANG Yaping PAN Shaoming ZHANG Rui LI Jun BAI Fenglong | 2008 | Acta Oceanologica Sinica2008，27，4： | 7 |

| 10 | Oxyvanite V3O5:A new intercalation-type anode for lithium-ion battery显示文摘In the present study,V3O5 microcrystals that synthesized via vacuum calcination are employed as anodes for lithium-ion batteries(LIBs)for the first time.Despite the widely observed sluggish reaction kinetics and poor cycling stability in most microsized transition metal oxides,the V3O5 microcrystals exhibit excellent rate capability(specific capacities of 144 and 125 mAh g^−1 are achieved at extremely high current densities of 20 and 50 A g^−1,respectively)and long-term cycling performance(specific capacity of 117 mAh g^−1 is sustained over 2000 cycles at 50 A g^−1).It is ascribed to the three-dimensional open-framework structure of the V3O5 microcrystals as a major factor in dictating the fast reaction kinetics(lithium diffusion coefficient:~10−9 cm^2 s^−1).In addition,significant insight into the reaction mechanism of the V3O5 microcrystals in concomitant its phase evolution are obtained from ex-situ XRD study,revealing that the V3O5 microcrystals undergo intercalation reaction with insignificant structural change in response to lithiation/delithiation. | Dong Chen Huiteng Tan Xianhong Rui Qi Zhang Yuezhan Feng Hongbo Geng Chengchao Li Shaoming Huang Yan Yu | 2019 | InfoMat2019，1，2： | 6 |
| 11 | Improvement of Foaming and Emulsifying Properties of Gluten by Conjugation with Fructose through Maillard Reaction显示文摘Gluten has poor emulsifying and foaming ability due to its amino acid composition. In this study, Maillard reaction was used to improve the emulsifying and foaming properties of gluten. The processing conditions for the preparation of gluten-fructose conjugates were optimized by using Box-Behnken model to achieve optimum foaming and emulsifying activity, respectively.The results showed that glycated gluten exhibited enhanced emulsifying activity compared to native control. The processing conditions for the preparation of gluten-fructose conjugates with optimum emulsifying activity were as follows: the temperature was 48℃, reaction time was 72 h, and maltose/gluten(W/W) ratio was 125%. Under such condition, the average emulsifying activity was 66.54%, being improved by about 2.5 times compared with that of native control. The Foaming properties of gluten also increased significantly by glycation modification. The optimum conditions of response were as below: the temperature was 48℃, reaction time was 66 h, and maltose/gluten ratio(W/W) was 110%. Under such condition, the average foaming property was 158.57%, and it was three folds higher than that of the control. | SONG Yongling QIN Ruiqi YANG Shaoming LI Jianghe WANG Ruolan | 2018 | Grain & Oil Science and Technology2018，1，3： | 5 |
| 12 | Traditional Chinese Medicine syndrome elements of male infertility revealed by latent tree model analysis显示文摘OBJECTIVE: To explore the features of Traditional Chinese Medicine(TCM) syndromes in male infertility using computer-based analyses.METHODS: Latent class analysis was used to analyze the TCM syndrome data from 813 patients with male infertility and establish a latent tree model.RESULTS: A latent tree model with a Bayesian information criterion score of-11 263 was created.This model revealed that the characteristics of basic TCM syndromes in patients with male infertility were kidney Yang deficiency, kidney Qi deficiency,spleen Yang deficiency, liver Qi stagnation, Qi stagnation and blood stasis, and dump-heat; moreover,most patients with male infertility had complex syndromes(spleen-kidney Yang deficiency and liver Qi stagnation) rather than simple single syndromes.CONCLUSION: The hidden tree model analysis revealed the objective and quantitative complex relationships between the TCM symptoms of male infertility, and obtained the quantification and objective evidence of TCM syndromes in male infertility. | Zhang Zhijie Liu Shaoming Zhang Yueyang Yang Jingzhe Kong Tao Wang Chengli Ning Peng Chen Xiaochao Li Xuesong Jia Yusen Chen Xiaojun | 2018 | Journal of Traditional Chinese Medicine2018，38，6： | 5 |
| 13 | The essential oil components of Cinnamomum cassia: an analysis under different thinning models of plantation Pinus massoniana显示文摘Thinning is an important activity employed in forest management. To date, studies have mainly focused on the effects of thinning on the growth of trees during the same thinning period. In this study, plantation Pinus massoniana Lamb. near maturity were thinned at varying intensities and an economically important species, Cinnamomum cassia Presl., was planted beneath the thinned canopy. The aim of the study was to explore the effects of the extent of thinning on the essential oil content and its components of C. cassia in different parts of the plant, as well as the economic feasibility of the P. massoniana–C.cassia management model. Thinning significantly reduced the oil yield in the bark and branches of C. cassia, but hardly impacted the oil yield from C. cassia leaves compared with pure C. cassia forest(CK). Among the different thinning treatments, both light(T.4) and extensive(T.1)thinning reduced the oil yield of C. cassia bark and new branches. The concentrations of the main aldehydes differed in different parts of the plant and were affected by the extent of thinning. The influence on cinnamaldehyde in the bark was minor, but was much greater in the branches and leaves. Both the oil yield and content of cinnamaldehyde showed that moderate(T.3) thinning was more favorable than other thinning models. These results not only provide a potentially promising model for the transformation of low–yield artificial pure forests of P. massoniana in the future, but also offer a reference for the management of artificial mixed stands. | Dayan Tao Yuanfa Li Daodiao Lu Yehong Luo Sufang Yu Shaoming Ye | 2016 | Journal of Forestry Research2016，27，3： | 5 |
| 14 | Trends in Incidence Rates,Mortality Rates,and Age-Period-Cohort Effects of Cervical Cancer—China,2003–2017显示文摘Introduction:This study reported the trends and analyzed the age-period-cohort effects on the incidence and mortality rates of cervical cancer in China.Methods:The age-standardized incidence rate(ASIR)and mortality rate(ASMR)by Segi’s world standard population were calculated using qualified consecutive data from 22 cancer registries from 2003 to 2017 in China.We performed joinpoint analysis to describe the trends and age-period-cohort analysis to estimate the independent effects of age,period and cohort on trends in incidence and mortality rates of cervical cancer.Results:The ASIR and ASMR for cervical cancer in females over 20 years old increased during 2003−2017.For females<50 years,a decreasing trend in ASIR and a stable trend in ASMR were observed in urban areas after 2009.But the ASIR and ASMR kept increasing in rural areas during the whole period.For females>50 years,the ASIR and ASMR increased both in urban and rural areas.Age-period-cohort analysis showed increasing period effects on cervical cancer incidence and mortality during the whole period.The cohort effects exhibited a downward-upwarddownward pattern for the incidence(1918–1938,1938–1963,1963–1993)and mortality rates(1918–1943,1943–1963,1963–1993)in urban areas,a fluctuating pattern for incidence rate and a continuing downward pattern for mortality rate(1918–1993)in rural areas.Conclusions:The increases in cervical cancer incidence and mortality rates can be mostly explained by period effects.We observed decreases in risk for cervical cancer incidence and mortality in young female generations,which were more obvious in urban areas. | Kexin Sun Rongshou Zheng Lin Lei Siwei Zhang Hongmei Zeng Shaoming Wang Li Li Ru Chen Bingfeng Han Ji Peng Wenqiang Wei Jie He | 2022 | China CDC weekly2022，4，48： | 4 |
| 15 | Temporal gravity changes before the 2008 Yutian Ms7.3 earthquake显示文摘Based on the data of the repeated gravity observation network in Chinese mainland since 1998,we analyzed the temporal changes of regional gravity field before the 2008 Yutian Ms7.3 earthquake.The result shows some mid-to-long term(two to ten years)changes during the earthquake's preparation.Notable features are a gravity increase lasting several years and a relatively large-scaled gradient zone of gravity change,the former indicating a continuous energy accumulation and the latter a possible location of seismic rupture.These gravity changes showed a trend of increase-accelerated increase-decelerated increase,similar to that of the Tangshan Ms7.8 earthquake in 1976.The maximum accumulated gravity change related to the earthquake reached 200×10-8 ms-2. | Shen Chongyang Li Hui Sun Shaoan Yang Guangliang Xuan Songbai Tan Hongbo Liu Shaoming | 2012 | Geodesy and Geodynamics2012，3，1： | 3 |

| 17 | Spatial pattern dynamics among co-dominant populations in early secondary forests in Southwest China显示文摘The canopy of subtropical natural forests usually consists of several co-dominant populations(CDPs),which play a crucial role in forest structure,formation of the forest environment,and ecological function.However,little attention has been given to changes in spatial patterns in CDPs during natural succession.Cyclobalanopsis glauca(Thunb.)Oerst.,Quercus variabilis Blume,and Pinus yunnanensis var.tenuifolia W.C.Cheng & Y.W.Law are canopy species that form CDPs in zonal forests along the Nanpan River in southwest China.We used the g(r) function and its bivariate distribution model,g_(12)(r),which is based on distances between pairs of points,to explore the dynamics of the three CDP species with respect to distribution patterns and spatial correlations in two secondary forests(one 30-year-old forest [30-YF] and one 57-year-old forest [57-YF]).The following key results were obtained:(1) there was a clumped pattern in the 30-YF,but the intensity of aggregation varied among populations and life stages.The distribution pattern gradually shifted to become random with longer succes sion time(i.e.,30-YF vs.57-YF),expansion of the observation scale(r=0-20 m),and at later life stages.(2) Aside from the mid-sized C.glauca trees and large P.yunnanensis trees,the trees repulsed each other at certain scales(r=0-2,5-6,11-12,14-16 m) in the 30-YF.Almost all of the life stages in the CDPs were independently correlated.This independent correlation was exacerbated by a longer succession time.(3) An increase in life stages and longer succession also promoted independent changes in intraspecific correlations.(4) Intraspecific correlations were stronger than interspecific correlations.Our results showed that reducing exclusive competition is essential to coexistence in CDPs.Inter-and intra-specific repulsion may occur at the same time,but intraspecific repulsion was the main driving force behind the random distributions and independent correlations. | Yuanfa Li Minghui Li Angang Ming Hongxiang Wang Sufang Yu Shaoming Ye | 2021 | Journal of Forestry Research2021，32，4： | 3 |
| 18 | Identification of maize seed varieties based on near infrared reflectance spectroscopy and chemometrics显示文摘False seeds can often be seen in the maize seed market,leading to a serious decline in maize yield.Those existing variety identification methods are expensive,time consuming,and destructive to seeds.The aim of this study is to develop a cheap,fast and non-destructive method which can robustly identify large amounts of maize seed varieties based on near-infrared reflectance spectroscopy(NIRS)and chemometrics.Because it is difficult to establish models for every variety in the market,this study mainly investigated the performance of models based on a large number of samples(more than 40 major varieties in the market).The reflectance spectra of maize seeds were collected by two modes(bulk kernels mode and single kernel mode).Both collection modes can be applied to identification,but only the single kernel mode can be applied to purity sorting.The spectra were pretreated with smoothing,the first derivative and vector normalization;and then principal component analysis(PCA),linear discriminant analysis(LDA)and biomimetic pattern recognition(BPR)were applied to establish identification models.The environmental factors such as producing areas and years have a significant influence on the performance of the models.Therefore,the method to improve the robustness of the models was investigated in this study.New indexes(correct acceptance degree(CAD),correct rejection degree(CRD)and correct degree(CD))were defined to analyze the performance of the models more accurately.Finally,the models obtained a mean correct discrimination rate of over 90%,and exhibited robust properties for samples harvested from different areas and years.The results showed that NIR technology combined with chemometrics methods such as PCA,LDA,and BPR could be a suitable and alternative technique to identify the authenticity of maize seed varieties. | Yongjin Cui Lanjun Xu Dong An Zhe Liu Jiancheng Gu Shaoming Li Xiaodong Zhang Dehai Zhu | 2018 | International Journal of Agricultural and Biological Engineering2018，11，2： | 3 |
| 19 | Carbon-nanoparticle-assisted growth of high quality bilayer WS2 by atmospheric pressure chemical vapor deposition显示文摘Two-dimensional(2D)WS2 offers great prospects for assembling next-generation optoelectronic and electronic devices due to its thickness-dependent optical and electronic properties.However,layer-number-controlled growth of WS2 is still a challenge up to now.This work presents controlled growth of bilayer WS2 triangular flakes by carbon-nanoparticle-assisted chemical vapor deposition(CVD)process.The growth mechanism is also proposed.In addition,the field effect transistors(FETs)based on monolayer and bilayer WS2 are also fabricated and investigated.The bilayer FET displays a mobility of 34 cm2·V^-1·s^-1,much higher than that of the monolayer FET.The high figures of merit make bilayer WS2 a promising candidate in high-performance electronics and optoelectronics. | Jieyuan Liang Lijie Zhang Xiaoxiao Li Baojun Pan Tingyan Luo Dayan Liu Chao Zou Nannan Liu Yue Hu Keqin Yang Shaoming Huang | 2019 | Nano Research2019，12，11： | 2 |
| 20 | Pomegranate-inspired porous SnSe/ZnSe@C anode:A stress-buffer nanostructure for fast and ultrastable sodium-ion storage显示文摘Tin selenide(SnSe)is considered as a potential anode for sodium-ion batteries(SIBs)owing to its high theoretical specific capacity.Unfortunately,it suffers from drastic volume expansion/contraction during sodium ions insertion/extraction,resulting in poor cycling stability.Herein,a pomegranate-inspired porous carbon shell wrapped heterogeneous SnSe/ZnSe composite(SnSe/ZnSe@C)is exquisitely designed and fabricated through electrostatic spraying followed by high-temperature selenization.The polyacrylonitrile-derived carbon shell acts as an adhesive to link the porous cubic SnSe/ZnSe and form highly interconnected microcircuits to improve the electron/ion transfer efficiency and inhibit the bulk volume change of internal metallic selenide nanoparticles and polyselenides dissolution during repeated cycling.Moreover,the abundant heterostructure interface of SnSe/ZnSe further significantly accelerates the electrons/ions transport.As a result,the as-prepared SnSe/ZnSe@C electrode exhibits a high specific capacity(508.3 m Ah g^(-1)at 0.05 A g^(-1)),excellent rate performance(177.8 m Ah g^(-1)at 10.0 A g^(-1)),and remarkable cycling stability(195.9 m Ah g^(-1)after 10,000 cycles at 5.0 A g^(-1)).Furthermore,in-situ Xray diffraction(XRD)/Raman,ex-situ transmission electron microscopy,and kinetic analysis clearly reveal a four-step electrochemical reaction process and battery-capacitor dual-mode sodium storage mechanism.This work provides a new perspective for developing commercial SIBs anode materials with high capacity and long lifespan. | Zhixin Liang Qinghua Li Wang Zhang Dandan Yu Wei Zhang Jiawei Wu Gaoyu Wang Wenbo Fan Junling Wang Shaoming Huang | 2022 | Journal of Energy Chemistry2022，，12： | 2 |
