| 2 | Dendrite‐free lithium and sodium metal anodes with deep plating/stripping properties for lithium and sodium batteries显示文摘Although lithium(Li)and sodium(Na)metals can be selected as the promising anode materials for next‐generation rechargeable batteries of high energy density,their practical applications are greatly restricted by the uncontrollable dendrite growth.Herein,a platinum(Pt)–copper(Cu)alloycoated Cu foam(Pt–Cu foam)is prepared and then used as the substrate for Li and Na metal anodes.Owing to the ultrarough morphology with a threedimensional porous structure and the quite large surface area as well as lithiophilicity and sodiophilicity,both Li and Na dendrite growths are significantly suppressed on the substrate.Moreover,during Li plating,the lithiated Pt atoms can dissolve into Li phase,leaving a lot of microsized holes on the substrate.During Na plating,although the sodiated Pt atoms cannot dissolve into Na phase,the sodiation of Pt atoms elevates many microsized blocks above the current collector.Either the holes or the voids on the surface of Pt–Cu foam what can be extra place for deposited alkali metal,what effectively relaxes the internal stress caused by the volume exchange during Li and Na plating/stripping.Therefore,the symmetric batteries of Li@Pt–Cu foam and Na@Pt–Cu foam have both achieved long‐term cycling stability even at ultrahigh areal capacity at 20 mAh cm−2. | Jianyi Wang Qi Kang Jingchao Yuan Qianru Fu Chunhua Chen Zibo Zhai Yang Liu Wei Yan Aijun Li Jiujun Zhang | 2021 | Carbon Energy2021，3，1： | 6 |
| 3 | Why can soil maintain its endless eco-cycle? The relationship between the mechanical properties and ecological attributes of soil显示文摘Dear Editors,Why can soil maintain its endless eco-cycle to sustain the growth of plants?This mystery of nature can be resolved by revealing the relationship between the mechanical properties and ecological attributes of soil.Traditionally,soil science[1-3]is divided into two main categories:pedology and edaphology.In addition,soil mechanics addresses soil from the perspective of mechanics and engineering[4,5].However,no inherent | ZhiJian Yi ChaoHua Zhao JianYi Gu QingGuo Yang Ya Li Kai Peng | 2016 | Science China(Physics,Mechanics & Astronomy)2016，59，10： | 4 |
| 4 | A cross-association model for CO_2-methanol and CO_2-ethanol mixtures显示文摘A cross-association model was proposed for CO2-alcohol mixtures based on the statistical associating fluid theory (SAFT).CO2 was treated as a pseudo-associating molecule and both the self-association between alcohol hydroxyls and the cross-association between CO2 and alcohol hydroxyls were considered.The equilibrium properties from low temperature-pressure to high temperature-pressure were investigated using this model.The calculated p-x and p-p diagrams of CO2-methanol and CO2-ethanol mixtures agreed with the experimental data.The results showed that when the cross-association was taken into account for Helmholtz free energy,the calculated equilibrium properties could be significantly improved,and the error prediction of the three phase equilibria and triple points in low temperature regions could be avoided. | FU Dong,YANG Zhuang,LU JianYi & LIU JianMin School of Environmental Science and Engineering,North China Electric Power University,Baoding 071003,China | 2010 | Science China Chemistry2010，53，6： | 4 |
| 5 | Factor decomposition of carbon emissions in Chinese megacities显示文摘In this article, per capita urban carbon emissions were decomposed into manufacturing,transportation, and construction sectors using logarithmic mean Divisia index(LMDI)method. This new decomposition method can provide information about specific drivers of carbon emissions, including urban growth and resident living standards, rather than general demographic and economic factors identified by traditional methods. Using four Chinese megacities(Beijing, Tianjin, Shanghai, and Chongqing) as case studies, we analyzed the factors that influenced per capita carbon emissions from 2010 to 2015. The results showed that per capita carbon emissions increased in Tianjin and Chongqing whereas decreased in Beijing and Shanghai, and that manufacturing was a key driving force. In these four megacities,energy conservation strategies were successfully implemented despite poor energy structure optimization during 2010–2015. Development of manufacturing and improvement of resident living standards in the cities led to an increase in carbon emissions. The unique dual-core urban form of Tianjin might mitigate the increased carbon emissions caused by the transportation sector. Reductions in carbon emissions could be achieved by further optimizing energy structures, limiting the number of private cars, and controlling per capita construction. | Longyu Shi Jing Sun Jianyi Lin Yang Zhao | 2019 | Journal of Environmental Sciences2019，31，1： | 4 |
| 6 | An improved surface-plasmonic nanobeam cavity for higher Q and smaller V显示文摘We demonstrate a high-Q hybrid surface-plasmon-polariton-photonic crystal(SP3C) nanobeam cavity.The proposed cavities are analyzed numerically using the three-dimensional finite difference time domain(3D-FDTD) method.The results show that a Q-factor of 2076 and a modal volume V of 0.16(/2n) 3 can be achieved in a 50 nm silica-gap hybrid SP3C nanobeam cavity when it operates at telecommunications wavelengths and at room temperature.V can be further reduced to 0.02(/2n) 3 when the silica thickness decreases to 10 nm,which leads to a Q/V ratio that is 11 times that of the corresponding plasmonic-photonic nanobeam cavity(without silica).The ultrahigh Q/V ratio originates from the low-loss nature and deep sub-wavelength confinement of the hybrid plasmonic waveguide,as well as the mode gap effect used to reduce the radiation loss.The proposed structure is fully compatible with semiconductor fabrication techniques and could lead to a wide range of applications. | YU Ping QI Biao XU Chao HU Ting JIANG XiaoQing WANG MingHua YANG JianYi | 2012 | Chinese Science Bulletin2012，57，25： | 4 |

| 9 | Modeling and Optimal Design of Planar Linkage Mechanism of Coupled Joint Clearances for Manufacturing显示文摘The uncertainty of the mechanism motion error is mostly caused by the manufacturing process,so the motion error cannot be effectively predicted at the design phase.The problems of manufacturing complexity and the relationship between design and manufacturing are analyzed,and the influence of dimensional tolerance and fit tolerance on the motion accuracy of the system is considered in the design process.Then based on the Monte Carlo simulation,an optimal design model of planar linkage mechanism is set up.A typical offset slider-crank mechanism is used as an illustrative example to carry out the optimal design.Compared with the result of typical robustness design,the similar variation characteristics of the mean value and the standard deviation can be found,so the proposed method is effective.The method is furthermore applied in the optimization of the schemes with different fit tolerances and the prediction of motion errors in the design phase is achieved.A set of quantitative evaluation system for mechanism optimal design is provided.Finally,a basic strategy is presented to balance the motion precision and manufacturing cost. | Yang Bo Wang Xingdong Kong Jianyi Zhang Hua | 2018 | Transactions of Nanjing University of Aeronautics and Astronautics2018，35，4： | 3 |
| 10 | Decomposition and decoupling analysis of carbon dioxide emissions in African countries during 1984–2014显示文摘The potential for mitigating climate change is growing worldwide,with an increasing emphasis on reducing CO_(2)emissions and minimising the impact on the environment.African continent is faced with the unique challenge of climate change whilst coping with extreme poverty,explosive population growth and economic difficulties.CO_(2)emission patterns in Africa are analysed in this study to understand primary CO_(2)sources and underlying driving forces further.Data are examined using gravity model,logarithmic mean divisia index and Tapio's decoupling indicator of CO_(2)emissions from economic development in 20 selected African countries during 1984-2014.Results reveal that CO_(2)emissions increased by 2.11%(453.73 million ton)over the research period.Gravity centre for African CO_(2)emissions had shifted towards the northeast direction.Population and economic growth were primary driving forces of CO_(2)emissions.Industrial structure and emission efficiency effects partially offset the growth of CO_(2)emissions.The economic growth effect was an offset factor in central African countries and Zimbabwe due to political instability and economic mismanagement.Industrial structure and emission efficiency were insufficient to decouple economic development from CO_(2)emissions and relieve the pressure of population explosion on CO_(2)emissions in Africa.Thus,future efforts in reducing CO_(2)emissions should focus on scaleup energy-efficient technologies,renewable energy update,emission pricing and long-term green development towards sustainable development goals by 2030. | Claudien Habimana Simbi Jianyi Lin Dewei Yang Jean Claude Ndayishimiye Yang Liu Huimei Li Lingxing Xu Weijing Ma | 2021 | Journal of Environmental Sciences2021，33，4： | 3 |
| 11 | Identifying human body states by using a flexible integrated sensor显示文摘Flexible sensors are required to be lightweight,compatible with the skin,sufficiently sensitive,and easily integrated to extract various kinds of body vital signs during continuous healthcare monitoring in daily life.For this,a simple and low-cost flexible temperature and force sensor that uses only two carbon fiber beams as the sensing layer is reported in this work.This simple,flexible sensor can not only monitor skin temperature changes in real time but can also extract most pulse waves,including venous waves,from most parts of the human body.A pulse diagnostic glove containing three such flexible sensors was designed to simulate pulse diagnostic methods used in traditional Chinese medicine.Wearable equipment was also designed in which four flexible sensors were fixed onto different body parts(neck,chest,armpit,and fingertip)to simultaneously monitor body temperature,carotid pulse,fingertip artery pulse,and respiratory rate.Four important physiological indicators—body temperature(BT),blood pressure(BP),heart rate(HR),and respiratory rate(RR)—were extracted by the wearable equipment and analyzed to identify exercise,excited,tired,angry,and frightened body states. | Ying Jin Guoning Chen Kete Lao Songhui Li Yong Lu Yufeng Gan Zhundong Li Jiajia Hu Jingcheng Huang Jinxiu Wen Honggui Deng Min Yang Zhiming Chen Xiaoyan Hu Baowen Liang Jianyi Luo | 2020 | npj Flexible Electronics2020，4，1： | 2 |
| 12 | Review of surface transient charge measurement on solid insulating materials via the Pockels technique显示文摘Surface charges accumulated on solid insulating materials in electrical apparatuses and electronic devices could distort the initial electric field and severely damage the insulation performance.Accurate transient surface charge measurement is critical to determine the mechanisms of charge transport and flashover occurrence,and estimate surface insulation strength under high voltage.The measurement technique based on the Pockels electro-optic effect is considered as the only approach for 2-D dynamic charge distribution behaviour so far,and it has good capability to avoid original electric field distortion caused by conven-tional methods featured by metal probes.This paper reviews recent progress of the non-invasive dynamic surface charge measurement systems on the Pockels technique.We focus especially on typical systems with transmitting and reflecting configurations and the frequently used fast inversion algorithms.It can be inferred that higher spatial-temporal resolution,higher signal-to-noise ratio,and better compatibility for both transparent and opaque materials are the future development trends,which greatly depend on multiple technological breakthroughs at impact-resistant electro-optic crystals,advanced high-speed photography and high-performance inversion algorithms.In addition,the recent studies on transient behaviour of surface discharge,together with the present limitation and future prospects are discussed.It is expected that more ideas will be inspired in transient surface charge measurement by the Pockels technique and other relevant electro-optic methods. | Bo Zhang Jianyi Xue Xingyu Chen Sile Chen Haibao Mu Yang Xu Guanjun Zhang | 2021 | High Voltage2021，6，4： | 2 |

We describe all the left cells and two-sided cells of the weighted Coxeter group(W,S,L) that have non-empty intersection with W_J,where the weight function L of(W, S) is in one of the following cases:(i) max{L(s) | s ∈J} < min{L(t)|t∈I};(ii) min{L(s)|s ∈J} ≥L(w_0);(iii) there exists some t ∈ I satisfying L(t) < L(s) for any s ∈I-{t} and L takes a constant value L_J on J with L_J in some subintervals of [1, L(w_0)-1]. The results in the case(iii) are obtained under a certain assumption on(W, W_I). | Jianyi Shi Gao Yang | 2018 | Science China Mathematics2018，61，2： | 2 |
| 14 | Silicon photonic network-on-chip and enabling components显示文摘As the transistor's feature scales down and the integration density of the monolithic circuit increases continuously,the traditional metal interconnects face significant performance limitation to meet the stringent demands of high-speed,low-power and low-latency data transmission for on-and off-chip communications.Optical technology is poised to resolve these problems.Due to the complementary metal-oxide-semiconductor(CMOS) compatible process,silicon photonics is the leading candidate technology.Silicon photonic devices and networks have been improved dramatically in recent years,with a notable increase in bandwidth from the megahertz to the multi-gigahertz regime in just over half a decade.This paper reviews the recent developments in silicon photonics for optical interconnects and summarizes the work of our laboratory in this research field. | HU Ting QIU Chen YU Ping YANG LongZhi WANG WanJun JIANG XiaoQing YANG Mei ZHANG Lei YANG JianYi | 2013 | Chinese Science Bulletin2013，58，7： | 2 |
| 15 | Thermally enhanced responsivity in an all-silicon optical power monitor based on defect-mediated absorption显示文摘We demonstrate a high responsivity all-silicon in-line optical power monitor by using the thermal effect to enhance the quantum efficiency of defect-mediated absorption at 1550 nm.The doping compensation technique is utilized to increase the density of lattice defects responsible for the sub-bandgap absorption and suppress the detrimental free carrier absorption.The 200-μm-long device presents a propagation loss as low as 2.9 d B/cm.Its responsivity is enhanced from 12.1 m A/W to 112 m A/W at-9 V bias by heating the optical absorption region.With this device,we build an optical power monitoring system that operates in the sampling mode.The minimal detectable optical power of the system is below-22.8 d Bm,while the average power consumption is less than1 m W at a sampling frequency of 10 Hz.Advantages of this scheme in terms of high responsivity,low insertion loss,and low power consumption lend itself to implement the feedback control of advanced large-scale silicon photonic integrated circuits. | QIKAI HUANG HUI YU QIANG ZHANG YAN LI WEIWEI CHEN YUEHAI WANG JIANYI YANG | 2021 | Photonics Research2021，9，11： | 1 |

| 18 | Metallurgy at the Crossroads: New Analyses of Copper-based Objects at Tianshanbeilu, Eastern Xinjiang, China显示文摘Tianshanbeilu is the largest Bronze Age site in eastern Xinjiang, China. Stretching across the entire second millennium BC, it performed a prominent role in connecting the Hexi corridor, Central China and the steppe. A further insight into the metallurgical tradition and the metal supply network is of vital importance to improve our understanding of its multi-connected nature. This paper offers a new set of chemical and isotopic data on the copper-based objects at Tianshanbeilu, including alloying elements, trace elements(impurities) and lead isotopes. Combining the concentrations of arsenic and antimony reveals that arsenic was introduced to copper partially due to the use of specific minerals tethrahedrite-tennantite. Lead isotopes demonstrate that multiple sources of copper were employed at Tianshanbeilu and a majority of them are characterized by common lead, which appears rather different from those of the Central Plains and the Hexi corridor, but highly consistent with local ores. Surprisingly, one object at Tianshanbeilu contains the well-known highly radiogenic lead. This object undoubtedly marks the westernmost boundary of the distribution of the highly radiogenic lead. We also anticipate that more lead isotopic analyses in NW China will further contribute to the study of the highly radiogenic lead in Central China. | LIU Cheng LIU Ruiliang ZHOU Pengcheng LU Chun YANG Zengxin A.Mark POLLARD Peter HOMMEL MA Jian CUI Jianfeng Peter BRAY TONG Jianyi Jessica RAWSON | 2020 | Acta Geologica Sinica(English Edition)2020，94，3： | 1 |
| 19 | Simulation of aggregation effects on co-fired biomass-coal ash in an electrostatic precipitator显示文摘Aggregation of fine ash into larger particles benefits fly ash removal in an electrostatic precipitator.Thermal aggregation,turbulent aggregation,and electrical aggregation of fine ash (derived from co-firing of biomass fuel and anthracite coal) was simulated under different conditions in an electrostatic precipitator.A population balance model and user-defined function in Fluent were assumed to obtain aggregation kernel functions and calculate the aggregation effects on the co-combusted particles.The results show that electrical aggregation had an obvious effect on both micron-and submicron-sized particles.For submicron particles,the effect of thermal aggregation is about ten times greater than turbulent aggregation.Meanwhile,for micron-sized particles,turbulent aggregation is about seven times greater than thermal aggregation.Therefore,particle aggregation in the electrostatic precipitator mainly occurs because of electrical aggregation,supplemented by thermal aggregation and turbulent aggregation.When the flow velocity is 1.0 m/s,particle volume fraction is 1.4%,and biomass co-firing ratio is 10%,the effects of all three aggregation processes on ash particles are optimized. | Jianyi Lu Zhe Yang Bingyi Xu Zhiyong Zhou Chenxi Sun | 2020 | Particuology2020，18，3： | 1 |
