| 1 | Effects of stress dependent electrochemical reaction on voltage hysteresis of lithium ion batteries显示文摘Intercalation of lithium ions into the electrodes of lithium ion batteries is affected by the stress of active materials, leading to energy dissipation and stress dependent voltage hysteresis. A reaction-diffusion-stress coupling model is established to investigate the stress effects under galvanostatic and potentiostatic operations. It is found from simulations that the stress hysteresis contributes to the voltage hysteresis and leads to the energy dissipation. In addition, the stress induced voltage hysteresis is small in low rate galvanostatic operations but extraordinarily significant in high rate cases. In potentiostatic operations, the stresses and stress induced overpotentials increase to a peak value very soon after the operation commences and decays all the left time. Therefore,a combined charge-discharge operation is suggested, i.e., first the galvanostatic one and then the potentiostatic one. This combined operation can not only avoid the extreme stress during operations so as to prevent electrodes from failure but also reduce the voltage hysteresis and energy dissipation due to stress effects. | Haoliang LI Yicheng SONG Bo LU Junqian ZHANG | 2018 | Applied Mathematics and Mechanics(English Edition)2018，39，10： | 3 |

| 3 | Regulating Li transport in Li-magnesium alloy for dendrite free Li metal anode显示文摘Li metal has become a strong candidate for anode due to its high theoretical specific capacity and lowest electrochemical potential.However,the poor reversibility caused by continuous chemical and electrochemical degradation hinders the practical application of Li metal.Solid-solution-based metal alloy phases have been proposed as hosts for regulating the non-dendrite electrodeposition,but the fundamental understanding remains unclear due to the drastically different deposition behaviors of Li on them.Here we found the difference in the diffusion coefficient of Li atoms on solid-solution-based metal alloy phases(Li-Mg and Li-Ag alloys)was a major contributor to the different deposition behaviors.The low Li atom diffusion coefficient of Li-Mg alloy showed a preferential Li accumulation on the upper surface rather than the inward-growth plating of Li atoms into alloy foil in Li-Ag alloy.By the process of secondary recrystallization,we improved the diffusion coefficient of Li atoms in Li-Mg alloy that facilitates the inward transfer rather than surface plating of Li atoms.In this case,the recrystallized Li-Mg alloy underwent a solidsolution phase change in the delithiation-lithiation cycles which yielded a high Coulombic efficiency of 99.3%with a reversible gravimetric capacity of 2,874 mAh·g−1 and superior cycling stability over 5,000 h without dendrite growth. | Jinxi Wang Yadong Ye Hongmin Zhou Wei Zhang Zhaowei Sun Jiawen Zhu Hongchang Jin Huanyu Xie Haoliang Huang Yi Cui Rong Huang Zezhong Li Song Jin Hengxing Ji | 2023 | Nano Research2023，16，6： | 0 |

| 5 | Geo-environmental properties and microstructural characteristics of sustainable limestone calcined clay cement(LC3)binder treated Zn-contaminated soils显示文摘Limestone calcined clay cement(LC3)is an environment-friendly and sustainable cementitious material.It has recently gained considerable attention for the stabilization/solidification(S/S)of soils contaminated by heavy metals.However,the existing studies on S/S of Zn-contaminated soils using LC3 in terms of hydraulic conductivity and microstructural properties as compared to ordinary Portland cement(OPC)are limited.This study focuses on the evaluation of the mechanical,leaching,and microstructural characteristics of Zn-contaminated soils treated with different contents(0%,4%,6%,8%,and 10%)of low-carbon LC3.The engineering performance of the treated Zn-contaminated soils is assessed over time using unconfined compressive strength(UCS),hydraulic conductivity(k),toxicity characteristic leaching procedure(TCLP),and synthetic precipitation leaching procedure(SPLP)tests.Experimental results show that the UCS of Zn-contaminated soils treated with LC3 ranged from 1.47 to 2.49 MPa,which is higher than 1.63%–13.07%for those treated with OPC.The k of Zn-contaminated soils treated with LC3 ranged from 1.16×10^(−8)to 5.18×10^(−8)cm/s as compared to the OPC treated samples.For the leaching properties,the leached Zn from TCLP and SPLP is 1.58–321.10 mg/L and 0.52–284.65 mg/L as the LC3 contents ranged from 4%to 10%.Further,the corresponding pH modeling results indicate that LC3 promotes a relatively suitable dynamic equilibrium condition to immobilize the higher-level Zn contamination.In addition,microscopic analyses demonstrate that the formations of hydration products,i.e.,Zn(OH)_(2),Zn_(2)SiO_(4),calcium silicate hydrate(C–S–H),calcium silicate aluminate hydrate(C–A–S–H)gel,ettringite,and CaZn(SiO_(4))(H_(2)O),are the primary mechanisms for the immobilization of Zn.This study also provides an empirical formula between the UCS and k to support the application of LC3-solidified Zn-contaminated soils in practical engineering in the field. | Haoliang WU Heng SONG Xinpo SUN Yuzhang BI Shenjing FU Ning YANG | 2023 | Journal of Zhejiang University-Science A(Applied Physics & Engineering)2023，24，10： | 0 |
| 6 | Genetic polymorphisms and phylogenetic analyses of the Ü-Tsang Tibetan from Lhasa based on 30 slowly and moderately mutated Y-STR loci显示文摘As a result of the expansion of old Tibet on the Qinghai-Tibet Plateau,Tibetans diverged into three main branches,Ü-Tsang,Amdo,and Kham Tibetan.Ü-Tsang Tibetans are geographically distributed across the wide central and western portions of the Qinghai-Tibet Plateau while Lhasa is the central gathering place for Tibetan culture.The AGCU Y30,a 6-dye fluorescence kit including 30 slowly and moderately mutated Y-STR loci,has been validated for its stability and sensitivity in different biomaterials and diverse Chinese populations(Han and other minorities),and widely used in the practical work of forensic science.However,the 30 Y-STR profiling of Tibetan,especially forÜ-Tsang Tibetan,were insufficient.We utilized the AGCU Y30 to genotype 577Ü-Tsang Tibetan unrelated males from Lhasa in the Tibet Autonomous Region of China to fill up the full and accurate Y-STR profiles.A total of 552 haplotypes were observed,536(97.10%)of which were unique.One hundred and ninety-four alleles were observed at 26 single copy loci and the allelic frequencies ranged from 0.0017 to 0.8180.For the two multi-copy loci DYS385a/b and DYS527a/b,64 and 36 allelic combinations were observed,respectively.The gene diversity(GD)values ranged from 0.3079 at DYS391 to 0.9142 at DYS385a/b and the overall haplotype diversity(HD)was 0.9998,and its discrimination capacity(DC)was 0.9567.The population genetic analyses demonstrated that LhasaÜ-Tsang Tibetan had close relationships with other Tibetan populations from Tibet and Qinghai,especially withÜ-Tsang Tibetan.From the perspective of Y haplogroups,the admixture of the southward Qiang people with dominant haplogroup O-M122 and the northward migrations of the initial settlers of East Asia with haplogroup D-M175 hinted the Sino-Tibetan homologous,thus,we could not ignore the gene flows with other Sino-Tibetan populations,especially for Han Chinese,to characterize the forensic genetic landscape of Tibetan. | Jiuyang Ding Haoliang Fan Yongsong Zhou Zhuo Wang Xiao Wang Xuheng Song Bofeng Zhu Pingming Qiu | 2022 | Forensic Sciences Research2022，7，2： | 0 |
| 7 | A Method to Prepare Nano-sized Copper Particles and Rods on the Surface of Cu Composite Films显示文摘Nano-sized Copper(Cu)particles and rods were prepared by annealing Cu-Zr,and Cu-Al-Zr composite films on polyimide substrates.XRD,FESEM and EDS were used to characterize their microstructure and composition.Results show that faceted Cu particles are regular and pure Cu element.Furthermore,it was interesting to find that Cu nanorods might appear on the surface of annealed Cu-Al-Zr composite thin films.Based on the experimental results and analysis,it were speculated that these Cu particles are single crystals.The particle average sizes are closely related to the content of Zr as well as annealing temperature and atmosphere.This work may provide a new approach to prepare metal particles and nanorods on the surface of Cu composite films on polyimide substrates. | Sun Haoliang Ming, Wei Zhan Jingmei Song Zhongxiao Fei, Ma Xu Kewei | 2012 | 稀有金属材料与工程2012，41，S1： | 0 |

| 9 | Influence of Fe-rich phases and precipitates on the mechanical behaviour of Al-Cu-Mn-Fe-Sc-Zr alloys studied by synchrotron X-ray and neutron显示文摘A multiscale methodology using scanning and transmission electron microscope,synchrotron X-ray nano-tomography and micro-tomography,small angle neutron scattering,and in situ synchrotron X-ray diffrac-tion has been used,to reveal the effect of Fe-rich phases and precipitates on the mechanical behaviour of an Al-Cu-Mn-Fe-Sc-Zr alloy.Theα-Al grains size is reduced from 185.1μm(0 MPa)and 114.3μm(75 MPa)by applied pressure.Moreover,it has been demonstrated that suitable heat treatments modify the 3D morphology of Fe-rich phases from interconnected to a disaggregated structure that improves the mechanical properties of the alloy.The size and morphology evolution of fine precipitates under differ-ent ageing temperature and time are revealed.At ageing temperature of 160℃,the precipitates change from GP zones toθ’(around 75 nm in length)with ageing time increasing from 1 h to 24 h;the Vick-ers hardness increases from 72.0 HV to 110.7HV.The high ductility of the Sc,Zr modified Al-Cu alloy is related to the complex shape and the loss of interconnectivity of the Fe-rich particles due to the heat treatment.The evolution of the crystal lattice strains inα-Al,andβ-Fe calculated during tensile test us-ing in-situ synchrotron X-ray diffraction corroborates the influence of the microstructure in the ductility of the modified alloy. | Yuliang Zhao Dongfu Song Shengchuan Wu Shunfu Xie Haoliang Wang Mengmeng Wang Weiwen Zhang Zhenzhong Sun Yubin Ke Shanfeng Wang Wanxia Huang Ricardo Fernández | 2023 | Journal of Materials Science & Technology2023，，27： | 0 |
| 10 | On stress-induced voltage hysteresis in lithium ion batteries:Impacts of surface effects and interparticle compression显示文摘Application of silicon in high capacity electrodes of lithium ion battery suffers from stress effects and, in turn, affects voltage performance of battery. This paper established a reaction-diffusion-stress coupled model and investigated the stress induced voltage hysteresis with consideration of diffusion induced stress, surface effects and interparticle compression. It was found stress and stress induced voltage hysteresis depended on particle size. In big particles, diffusion induced stress is dominant and leads to significant hysteresis in both stress and voltage, indicating energy dissipation due to stress effects. In small particles, e.g.,radius of dozens nanometers, diffusion induced stress was negligible while surface effects played dominant role, leading to nearly vanished voltage hysteresis shifting away from equilibrium potential. According to calculation, particle sizes around 100 nm are appropriate choice for electrode design as both diffusion induced stress and surface effects are insignificant. Finally,interparticle compression pushed the stress hysteresis to compressive side and led to early termination of lithiation at cut-off voltage. Denser electrode would enhance this effect. It indicated that there must be a limit of mixing ratio of silicon because higher interparticle compressive stress due to more introduced silicon would impede the battery from fully charged. | JIN ChuanJian LI HaoLiang SONG YiCheng LU Bo SOH A.
