3Optical visualization and polarized light absorption of the single-wall carbon nanotube to verify intrinsic thermal applications显示文摘The predicted extraordinary properties of carbon nanotubes(CNTs)from theoretical calculations have great potential for many applications.However,reliable experimental determination of intrinsic properties at the single-tube level is currently a matter of concern,and many challenges remain because of the unhandled and nanoscale size of individual nanotubes.Here,we demonstrated a prototype to detect the intrinsic thermal conductivity of the single-wall carbon nanotube(SWCNT)and verify the significant non-resonant optical absorption behavior on tiny nanotubes by integrating the nanotube and ice into a new core-shell design.In particular,a reversible optical visualization method based on the individual suspended ultra-long SWCNT was first developed by wrapping a nanotube with ice in the cryogenic air environment.The light-induced thermal effect on the hybrid core-shell structure was used tomelt the ice shell,which subsequently acted as a temperature sensor to verify the intrinsic thermal conductivity of the core-like nanotube.More interestingly,we successfully determined for the first time the thermal response phenomenon of the tiny absorption cross section in SWCNT in the vertical-polarization configuration and the significant non-resonant absorption behavior in the parallel-polarization configuration.These investigations will provide a better understanding for the unique optical behaviors of CNT and enable the detection of intrinsic properties of various one-dimensional nanostructures such as nanotubes,nanowires,and nanoribbons.Xiao Zhang Li Song Le Cai Xuezeng Tian Qiang Zhang Xiaoying Qi Wenbin Zhou Nan Zhang Feng Yang Qingxia Fan Yanchun Wang Huaping Liu Xuedong Bai Weiya Zhou Sishen Xie 2015Light(Science & Applications)2015,4,1:2
4Recent development of studies on the mechanism of resistive memories in several metal oxides显示文摘Resistive switching random access memories(RRAM)have been considered to be promising for future information technology with applications for non-volatile memory,logic circuits and neuromorphic computing.Key performances of those resistive devices are approaching the realistic levels for production.In this paper,we review the progress of valence change type memories,including relevant work reported by our group.Both electrode engineering and in-situ transmission electron microscopy(TEM)high-resolution observation have been implemented to reveal the influence of migration of oxygen anions/vacancies on the resistive switching effect.The understanding of resistive memory mechanism is significantly important for device applications.TIAN XueZeng WANG LiFen LI XiaoMin WEI JiaKe YANG ShiZe XU Zhi WANG WenLong BAI XueDong 2013Science China(Physics,Mechanics & Astronomy)2013,56,12:2
5Improvement of precision for pendulous integrating gyro accelerometer via adaptive internal model control显示文摘An adaptive internal mode control is proposed to eliminate effectively periodic disturbance with uncertain frequency caused by input error angle of PIGA (Pendulous Integrating Gyro Accelerometer). An adaptive algorithm with periodic disturbance frequency identification on line is applied and the internal model controller parameters are adjusted to eliminate disturbance. Then the convergence of this algorithm and the stability of the system are proved by the averaging method. Simulation results verify the proposed scheme can eliminate periodic disturbance and improve the test precision for PIGA effectively.Xu Fengxia Xia Gang Zeng Ming Sun Baoku Zhao Xuezeng 2007Journal of Systems Engineering and Electronics2007,18,4:1

14In situ separator modification via CVD-derived N-doped carbon for highly reversible Zn metal anodes显示文摘Attention toward aqueous zinc-ion battery has soared recently due to its operation safety and environmental benignity.Nonetheless,dendrite formation and side reactions occurred at the anode side greatly hinder its practical application.Herein,we adopt direct plasma-enhanced chemical vapor deposition strategy to in situ grow N-doped carbon(NC)over commercial glass fiber separator targeting a highly stabilized Zn anode.The strong zincophilicity of such a new separator would reduce the nucleation overpotential of Zn and enhance the Zn-ion transference number,thereby alleviating side reactions.Symmetric cells equipped with NC-modified separator harvest a stable cycling for more than 1,100 h under 1 mA·cm^(−2)/1 mAh·cm^(−2).With the assistance of NC,the depth of discharge of Zn anode reaches as high as 42.7%.When assembled into full cells,the zinc-ion battery based on NC-modified separator could maintain 79%of its initial capacity(251 mAh·g^(−1))at 5 A·g^(−1) after 1,000 cycles.Xianzhong Yang Weiping Li Jiaze Lv Guojie Sun Zixiong Shi Yiwen Su Xueyu Lian Yanyan Shao Aomiao Zhi Xuezeng Tian Xuedong Bai Zhongfan Liu Jingyu Sun 2022Nano Research2022,15,11:1

17Evaluation of urban underground space resources using digitalization technologies显示文摘Exploitation and utilization of urban underground space resources is gaining increasing attention in cities’sustainable development.Due to the attributes of fragility and irreversibility,urban underground space resources can be extremely vulnerable to damage and it is often difficult in restoring their original state once damaged.Therefore,scientific and reasonable evaluation of urban underground space resources is of vital importance in urban planning and development.This paper first describes the content and methods for the evaluation of urban underground space resources,and introduces the digitalization technologies to handle the problems of strong subjectivity,low efficiency and rough precision encountered when using traditional evaluation tools.Then,the related concepts and main technologies for digitalization were demonstrated and an intelligent GIS-based engineering geology system was built.Based on the drilling information in Changzhou City,stratum standardization and 3D modeling of strata,underground structures and pipelines were conducted in the built intelligent system.Finally,with the help of spatial overlay analysis in the GIS-based platform and a combination of other digitalization technologies,the urban underground space resources of Changzhou City were evaluated.Maps of geological suitability were produced,which provide scientific guidance and reference for the exploitation and planning of urban underground space resources in Changzhou City.In addition,site selection for key projects was conducted based on the evaluation results using this platform.Hehua Zhu Xianbin Huang Xiaojun Li Lianyang Zhang Xuezeng Liu 2016Underground Space2016,1,2:1

20Meniscus fabrication of halide perovskite thin films at high throughput for large area and low-cost solar panels显示文摘Halide perovskites have rapidly attracted considerable attention due to unprecedented properties not seen in traditional semiconductors.In addition to their optoelectronic merits,one advantage of perovskite materials is their solution processability,which opens the door to low-cost and high throughput solution coating strategies for the commercialization of perovskite solar cells(PSCs).Here we review perovskite film fabrication by meniscus coating—a simple and readily scalable manufacturing technique,including blade coating and slot-die coating.We outline the fundamental fluid mechanisms of meniscus coating,discuss drying and crystallization of perovskite in the coating process,and provide an overview of recent progress in meniscus-coated PSCs.Xuezeng Dai Yehao Deng Charles H Van Brackle Jinsong Huang 2019International Journal of Extreme Manufacturing2019,1,2:1
