| 3 | TiO_2-coated SnO_2 hollow spheres as anode materials for lithium ion batteries显示文摘TiO2-coated SnO2(TCS) hollow spheres,which are new anode materials for lithium ion(Li-ion) batteries,were prepared and characterized with X-ray diffraction(XRD) ,scanning electron microscopy(SEM) ,transmission electron microscopy(TEM) ,cyclic voltammetry(CV) ,and galvanostatic charge/discharge tests.The results obtained from XRD,SEM,and TEM show that TiO2 can be uniformly coated on the surface of SnO2 hollow spheres with the assistance of anionic surfactant.The cyclic voltammograms indicate that both TiO2 and SnO2 ex-hibit the activity for Li-ion storage.The charge/discharge tests show that the prepared TCS hollow spheres have a higher reversible coulomb efficiency and a better cycling stability than the uncoated SnO2 hollow spheres. | YI Jin LI Xiaoping HU Shejun LI Weishan ZENG Ronghua FU Zhao CHEN Lang | 2011 | Rare Metals2011，30，6： | 4 |
| 4 | Highly dispersed Co-Mo sulfide nanoparticles on reduced graphene oxide for lithium and sodium ion storage显示文摘A novel hybrid,highly dispersed spinel Co-Mo sulfide nanoparticles on reduced graphene oxide(Co3S4/CoMo2S4@rGO),is reported as anode for lithium and sodium ion storage.The hybrid is synthesized by one-step hydrothermal method but exhibits excellent lithium and sodium storage performances.The as-synthesized Co3S4/CoMo2S4@rGO presents reversible capacity of 595.4 mA·h·g^−1 and 408.8 mA·h·g^−1 after 100 cycles at a current density of 0.2 A·g^−1 for lithium and sodium ion storages,respectively.Such superior performances are attributed to the unique composition and structure of Co3S4/CoMo2S4@rGO.The rGO provides a good electronically conductive network and ensures the formation of spinel Co3S4/CoMo2S4 nanoparticles,the Co3S4/CoMo2S4 nanoparticles provide large reaction surface for lithium and sodium intercalation/deintercalation,and the spinel structure allows fast lithium and sodium ion diffusion in three dimensions. | Yuqing Liao Chun Wu Yaotang Zhong Min Chen Luyang Cai Huirong Wang Xiang Liu Guozhong Cao Weishan Li | 2020 | Nano Research2020，13，1： | 4 |
| 5 | Insight into the interaction between Ni-rich LiNi0.8Co0.1Mn0.1O2 cathode and BF4--introducing electrolyte at 4.5V high voltage显示文摘Owing to the high specific capacity and high voltage,Ni-rich(LiNi0.8Co0.1Mn0.1O2,LNCM811)cathode has been considered as one of the most promising candidate cathode materials for next generation lithium ion batteries,whereas severe capacity fading greatly hinders its practical application.Notably,the compatibility of Ni-rich materials with LiBF4-containing electrolyte has not yet been realized.Herein,1 M LiPF6-based electrolyte with introducing 2 M LiBF4 is proposed to dramatically improve the cyclic stability of high voltage LNCM811/Li half-cell.Addition of high concentrated LiBF4 improves the moisture stability of electrolyte,which hinders the generation of harmful by-product HF,resulting in improved interfacial stability of LNCM811.Lithium plating/stripping reaction of Li/Li symmetric cell confirms that the enhanced cyclic stability is ascribed to the improved interfacial stability of LNCM811 instead of lithium electrode.Morphology and composition characterization results reveal that LiBF4 participates in the CEI film-forming reaction,resulting in suppressed oxidation of electrolyte and interfacial structural destruction of LNCM811. | Guangyuan Lan Hebing Zhou Lidan Xing Jiawei Chen Zifei Li Rude Guo Yanxia Che Weishan Li | 2019 | Journal of Energy Chemistry2019，28，12： | 3 |
| 6 | Revealing the critical effect of solid electrolyte interphase on the deposition and detriment of Co(Ⅱ) ions to graphite anode显示文摘'Dissolution,migration,and deposition'of transition metal ions (TMIs) result in capacity degradation of lithium-ion batteries (LIBs).Understanding such detrimental mechanism of TMIs is critical to the development of LIBs with long cycle life.In most previous works,TMIs were directly introduced into the electrolyte to investigate such a detrimental mechanism.In these cases,the TMIs are deposited directly on the fresh anode surface.However,in the practical battery system,the TMIs are deposited on the anode covered with solid electrolyte interphase (SEI) film.Whether the pre-presence of SEI film on anode surface influences the deposition and detriment of TMIs is unclear.In this work,the deposition of Co element on graphite anode with and without SEI film were systematically studied.The results clearly show that,in comparison with that of fresh graphite (SEI-free),the presence of SEI film aggravates the deposition of Co ions due to the Li^(+)–Co^(2+) ion exchange between the SEI and Co^(2+)-containing electrolyte without the driving of the electric field,leading to faster capacity fading of graphite anode.Therefore,how to regulate electrolytes and film-forming additives to design the components of SEI and prevent its exchange with TMIs,is a crucial way to inhibit the deposition and detriment of TMIs on graphite anode. | Qiming Xie Jiawei Chen Lidan Xing Xianggui Zhou Zekai Ma Binhong Wu Yilong Lin Hebing Zhou Weishan Li | 2022 | Journal of Energy Chemistry2022，31，6： | 2 |
| 7 | Inhibiting manganese(Ⅱ)from catalyzing electrolyte decomposition in lithium-ion batteries显示文摘A once overlooked source of electrolyte degradation incurred by dissolved manganese(Ⅱ)species in lithium-ion batteries has been identified recently.In order to deactivate the catalytic activity of such manganese(II)ion,1-aza-12-crown-4-ether(A12C4)with cavity size well matched manganese(Ⅱ)ion is used in this work as electrolyte additive.Theoretical and experimental results show that stable complex forms between A12C4 and manganese(II)ions in the electrolyte,which does not affect the solvation of Li ions.The strong binding effect of A12C4 additive reduces the charge density of manganese(II)ion and inhibits its destruction of the PF_(6)^(-)structure in the electrolyte,leading to greatly improved thermal stability of manganese(II)ions-containing electrolyte.In addition to bulk electrolyte,A12C4 additive also shows capability in preventing Mn^(2+) from degrading SEI on graphite surface.Such bulk and interphasial stability introduced by A12C4 leads to significantly improved cycling performance of LIBs. | Xuehuan Luo Lidan Xing Jenel Vatamanu Jiawei Chen Jiakun Chen Mingzhu Liu Cun Wang Kang Xu Weishan Li | 2022 | Journal of Energy Chemistry2022，31，2： | 2 |
| 8 | Phosphate limitation increases coenzyme Q10 production in industrial Rhodobacter sphaeroides HY01显示文摘Coenzyme Q10(CoQ10)is an important component of the respiratory chain in humans and some bacteria.As a high-value-added nutraceutical antioxidant,CoQ10 has excellent capacity to prevent cardiovascular disease.The content of CoQ10 in the industrial Rhodobacter sphaeroides HY01 is hundreds of folds higher than normal physiological levels.In this study,we found that overexpression or optimization of the synthetic pathway failed CoQ10 overproduction in the HY01 strain.Moreover,under phosphate-limited conditions(decreased phosphate or in the absence of inorganic phosphate addition),CoQ10 production increased significantly by 12%to220 mg/L,biomass decreased by 12%,and the CoQ10 productivity of unit cells increased by 27%.In subsequent fed-batch fermentation,CoQ10 production reached 272 mg/L in the shake-flask fermentation and 1.95 g/L in a 100-L bioreactor under phosphate limitation.Furthermore,to understand the mechanism associated with CoQ10 overproduction under phosphate-limited conditions,the comparatve transcriptome analysis was performed.These results indicated that phosphate limitation combined with glucose fed-batch fermentation represented an effective strategy for CoQ10 production in the HY01.Phosphate limitation induced a pleiotropic effect on cell metabolism,and that improved CoQ10 biosynthesis efficiency was possibly related to the disturbance of energy metabolism and redox potential. | Lu Zhang Leshi Liu Ke-Feng Wang Lan Xu Liming Zhou Weishan Wang Chuan Li Zheng Xu Tong Shi Haihong Chen Yuanhang Li Hui Xu XiuLiang Yang Zhichun Zhu Biqin Chen Dan Li Guanghuang Zhan Si-Liang Zhang Li-Xin Zhang Gao-Yi Tan | 2019 | Synthetic and Systems Biotechnology2019，4，4： | 2 |

| 14 | Integrating PCR-free amplification and synergistic sensing for ultrasensitive and rapid CRISPR/Cas12a-based SARS-CoV-2 antigen detection显示文摘Antigen detection provides particularly valuable information for medical diagnoses;however,the current detection methods are less sensitive and accurate than nucleic acid analysis.The combination of CRISPR/Cas12a and aptamers provides a new detection paradigm,but sensitive sensing and stable amplification in antigen detection remain challenging.Here,we present a PCR-free multiple trigger dsDNA tandem-based signal amplification strategy and a de novo designed dual aptamer synergistic sensing strategy.Integration of these two strategies endowed the CRISPR/Cas12a and aptamer-based method with ultra-sensitive,fast,and stable antigen detection.In a demonstration of this method,the limit of detection was at the single virus level(0.17 fM,approximately two copies/μL)in SARS-CoV-2 antigen nucleocapsid protein analysis of saliva or serum samples.The entire procedure required only 20 min.Given our system’s simplicity and modular setup,we believe that it could be adapted reasonably easily for general applications in CRISPR/Cas12a-aptamer-based detection. | Xiangxiang Zhao Zhengduo Wang Bowen Yang Zilong Li Yaojun Tong Yuhai Bi Zhenghong Li Xuekui Xia Xiangyin Chen Lixin Zhang Weishan Wang Gao-Yi Tan | 2021 | Synthetic and Systems Biotechnology2021，6，4： | 1 |
| 15 | A Practical Strategy of Unbalance Identification and Correction for 2-DOF Precision Centrifuges显示文摘Unbalance existing in the mechanical systems is one of the most common causes which leads to unexpected vibration,nonsmooth motions,uncertain dynamics and even instability. In this paper,the problem of unbalance identification and correction is investigated for the countershaft system of a precision centrifuge with two degrees of freedom. According to the characteristics of the load under test installed on the countershaft,a gradual subdivision algorithm is proposed to identify the phase of the unbalance,and its amplitude is calculated by using a space vector algorithm,where the vibration information of the mainshaft system is obtained by utilizing two axis-layout displacement transducers installed associated to the mainshaft.Based on ADAMS software,some numerical simulations are presented and compared,and further,the validity of the strategy is demonstrated by experimental examples. | Xin Huo Shuangpeng Zheng Yu Yao Weishan Chen | 2018 | Journal of Harbin Institute of Technology(New Series)2018，25，1： | 1 |

| 18 | An OSGi-based flexible and adaptive pervasive cloud infrastructure显示文摘There is a trend that diferent computing paradigms such as cloud computing,pervasive,and mobile computing are converging with each other.Due to this convergence,there arise unprecedented complexities,such as huge number of computing devices,flexibilities and adaptation of service infrastructure(infrastructure elasticity)for fitting dynamics of large smart city applications,expectations of powerful computing and storage capabilities on handhold devices,and so on.Therefore,a supporting infrastructure is needed,which can flexibly switch services at run time and can be used to enhance capabilities for small devices through component/service migrations.In this paper,we propose an elastic open service gateway initiative(OSGi)-based pervasive cloud(OSGi-PC)infrastructure which can make use of both the cloud computing capabilities and the component flexibilities from OSGi.OSGi-PC provides flexible management of component migrations between small devices themselves and powerful nodes in between,which is remaining a critical challenge for enabling mobile clouds.We have evaluated the OSGi-PC in terms of performance for adaptive service provision,and power consumption during service adaptation,performance and power consumption for component migrations in diferent scenarios,which show the usability of OSGi-PC. | ZHANG WeiShan CHEN LiCheng LIU Xin LU QingHua ZHANG PeiYing YANG Su | 2014 | Science China(Information Sciences)2014，57，3： | 1 |
