| 2 | Microstructure evolution and growth mechanism of core-shell silicon-based nanowires by thermal evaporation of SiO显示文摘Core-shell structured SiC@SiO_(2)nanowires and Si@SiO_(2)nanowires were prepared on the surface of carbon/carbon(C/C)composites by a thermal evaporation method using SiO powders as the silicon source and Ni(NO3)2 as the catalyst.The average diameters of SiC@SiO_(2)nanowires and Si@SiO_(2)nanowires are about 145 nm,and the core-shell diameter ratios are about 0.41 and 0.53,respectively.The SiO_(2)shells of such two nanowires resulted from the reaction between SiO and CO and the reaction of SiO itself,respectively,based on the model analysis.The growth of these two nanowires conformed to the vapor-liquid-solid(VLS)mode.In this mode,CO played an important role in the growth of nanowires.There existed a critical partial pressure of CO(pC)determining the microstructure evolution of nanowires into whether SiC@SiO_(2)or Si@SiO_(2).The value of pC was calculated to be 4.01×10^(-15) Pa from the thermodynamic computation.Once the CO partial pressure in the system was greater than the pC,SiO tended to react with CO,causing the formation of SiC@SiO_(2)nanowires.However,the decomposition of SiO played a predominant role and the products mainly consisted of Si@SiO_(2)nanowires.This work may be helpful for the regulation of the growth process and the understanding of the growth mechanism of silicon-based nanowires. | Bing LIU Jia SUN Lei ZHOU Pei ZHANG Chenxin YAN Qiangang FU | 2022 | Journal of Advanced Ceramics2022，11，9： | 1 |

| 4 | Stability of Sn-Pb mixed organic–inorganic halide perovskite solar cells:Progress,challenges,and perspectives显示文摘The exploration of low bandgap perovskite material to approach Shockley-Queisser limit of photovoltaic device is of great significance,but it is still challenging.During the past few years,tin–lead(Sn-Pb)mixed perovskites with low bandgaps have been rapidly developed,and their single junction solar cells have reached power conversion efficiency(PCE)over 21%,which also makes them ideal candidate as low bandgap sub-cell for tandem device.Nevertheless,due to the incorporation of unstable Sn^(2+),the stability issue becomes the vital problem for the further development of Sn-Pb mixed perovskite solar cells(PSCs).In this review,we are dedicated to give a full view in current understanding on the stability issue of SnPb mixed perovskites and their PSCs.We begin with the demonstration on the origin of instability of Sn-Pb mixed perovskites,including oxidation of Sn^(2+),defects,and interfacial layer induced instability.Sequentially,the up-to-date developments on the stability improvement of Sn-Pb mixed perovskites and their PSCs is systematically reviewed,including composition engineering,additive engineering,and interfacial engineering.At last,the current challenges and future perspectives on the stability study of Sn-Pb mixed PSCs are discussed,which we hope could promote the further application of Sn-Pb mixed perovskites towards commercialization. | Shaoshen Lv Weiyin Gao Yanghua Liu He Dong Nan Sun Tingting Niu Yingdong Xia Zhongbin Wu Lin Song Chenxin Ran Li Fu Yonghua Chen | 2022 | Journal of Energy Chemistry2022，31，2： | 1 |
| 5 | Direct electrochemistry behavior of Cytochrome c on silicon dioxide nanoparticles-modified electrode显示文摘A newfangled direct electrochemistry behavior of Cytochrome c (Cyt c) was found on glassy carbon (GC) electrode modified with the silicon dioxide (SiO2) nanoparticles by physical adsorption. A pair of stable and well-defined redox peaks of Cyt c′ quasi-reversible electrochemical reaction were obtained with a heterogeneous electron transfer rate constant of 1.66×10-3 cm/s and a formal potential of 0.069 V (vs. Ag/AgCl) (0.263 V versus NHE) in 0.1 mol/L pH 6.8 PBS. Both the size and the amount of SiO2 nanoparticles could influence the electron transfer between Cyt c and the electrode. Electrostatic interaction which is between the negative nanoparticle surface and positively charged amino acid residues on the Cyt c surface is of importance for the stability and reproducibility toward the direct electron transfer of Cyt c. It is suggested that the modification of SiO2 nanoparticles proposes a novel approach to realize the direct electrochemistry of proteins. | ZHU Lin SUN DongMei LU TianHong CAI ChenXin LIU ChangPeng XING Wei | 2007 | Science China Chemistry2007，50，3： | 1 |
| 6 | Phase Morphology Evolution in AISI301 Austenite Stainless Steel under Different Cooling Rates显示文摘Quenching experiments were performed at different cooling rates under non-directional solidification by differential thermal analysis, and the morphologic variation of primary phase, phase transition temperature and hardness change at the same quenching temperature were investigated. The experimental results show that, with the gradual decrease of the cooling rate from 25 K/min, the morphology of ferrite starts to transform experiencing the dendrite, radial pattern, Widmanstatten-like and wire-net. Sample starts to present the Widmanstatten-like microstructure at 10 K/min which does not exist at higher or lower cooling rates, and this microstructure is detrimental to the mechanical property. Except 10 K/min, the hardness decreases with decreasing cooling rate. | 白亮 麻永林 XING Shuqing LIU Chenxin ZHANG Jieyu | 2015 | Journal of Wuhan University of Technology(Materials Science)2015，30，2： | 0 |

| 8 | Individual blastomeres of 4-and 8-cell embryos have ability to develop into a full organism in mouse显示文摘Following fertilization in mammals,the zygote initiates the developmental program,which has a transient capacity to generate cell types of both embryonic and extraembryonic lineages,which is defined as totipotency (Condic,2014),In mice, only zygotes and blastomeres of 2-cell stage embryos are considered totipotent,since they have the ability to develop into a full organism without the requirement of carrier cells (Tarkowski, 1959;Ishiuchi and Torres-Padilla,2013).However,the blastomeres of the 4-cell or later stage embryos quickly lose this ability (Rossant,1976). | Xinxin Zhang Tianda Li Linlin Zhang Liyuan Jiang Tongtong Cui Xuewei Yuan Chenxin Wang Zhonghua Liu Ying Zhang Wei Li Qi Zhou | 2018 | Journal of Genetics and Genomics2018，45，12： | 0 |
| 9 | Intracavity spatiotemporal metasurfaces显示文摘Optical metasurfaces are endowed with unparallel flexibility to manipulate the light field with a subwavelength spatial resolution.Coupling metasurfaces to materials with strong optical nonlinearity may allow ultrafast spatiotemporal light field modulation.However,most metasurfaces demonstrated thus far are linear devices.Here,we experimentally demonstrate simultaneous spatiotemporal laser mode control using a single-layer plasmonic metasurface strongly coupled to an epsilon-near-zero(ENZ)material within a fiber laser cavity.While the geometric phase of the metasurface is utilized to convert the laser’s transverse mode from a Gaussian beam to a vortex beam carrying orbital angular momentum,the giant nonlinear saturable absorption of the ENZ material enables pulsed laser generation via the Q-switching process.The direct integration of a spatiotemporal metasurface in a laser cavity may pave the way for the development of miniaturized laser sources with tailored spatial and temporal profiles,which can be useful for numerous applications,such as superresolution imaging,high-density optical storage,and three-dimensional laser lithography. | Wenhe Jia Chenxin Gao Yongmin Zhao Liu Li Shun Wen Shuai Wang Chengying Bao Chunping Jiang Changxi Yang Yuanmu Yang | 2023 | Advanced Photonics2023，5，2： | 0 |
| 10 | Accurate RGB-D SLAM in dynamic environments based on dynamic visual feature removal显示文摘Visual localization is considered an essential capability in robotics and has attracted increasing interest for the past few years.However,most proposed visual localization systems assume that the surrounding environment is static,which is difficult to maintain in real-world scenarios due to the presence of moving objects.In this paper,we present DFR-SLAM,a real-time and accurate RGB-D SLAM based on ORB-SLAM2 that achieves satisfactory performance in a variety of challenging dynamic scenarios.At the core of our system lies a motion consensus filtering algorithm estimating the initial camera pose and a graph-cut optimization framework combining long-term observations,prior information,and spatial coherence to jointly distinguish dynamic and static visual features.Other systems for dynamic environments detect dynamic components by using the information from short time-span frames,whereas our system uses observations from a long period of keyframes.We evaluate our system using dynamic sequences from the public TUM dataset,and the evaluation demonstrates that the proposed system outperforms the original ORB-SLAM2 system significantly.In addition,our system provides competitive localization accuracy with satisfactory real-time performance compared to closely related SLAM systems designed to adapt to dynamic environments. | Chenxin LIU Jiahu QIN Shuai WANG Lei YU Yaonan WANG | 2022 | Science China(Information Sciences)2022，65，10： | 0 |
| 11 | Portable visual and electrochemical detection of hydrogen peroxide release from living cells based on dual-functional Pt-Ni hydrogels显示文摘It is important to monitor the intra-/extracellular concentration of hydrogen peroxide(H_(2)O_(2))in biological processes.However,miniaturized devices that enable portable and accurate H_(2)O_(2)measurement are still in their infancy because of the difficulty of developing facile sensing strategies and highly integrated sensing devices.In this work,portable H_(2)O_(2)sensors based on Pt-Ni hydrogels with excellent peroxidase-like and electrocatalytic activities are demonstrated.Thus,simple and sensitive H_(2)O_(2)sensing is achieved through both colorimetric and electrochemical strategies.The as-fabricated H_(2)O_(2)sensing chips exhibit favorable performance,with low detection limits(0.030μM&0.15μM),wide linearity ranges(0.10μM-10.0 mM&0.50μM-5.0 mM),outstanding long-term stability(up to 60 days),and excellent selectivity.With the aid of an M5stack development board,portable visual and electrochemical H_(2)O_(2)sensors are successfully constructed without complicated and expensive equipment or professional operators.When applied to the detection of H_(2)O_(2)released from HeLa cells,the results obtained by the developed sensors are in good agreement with those from an ultraviolet‒visible spectrophotometer(UV‒vis)(1.97μM vs.2.08μM)and electrochemical station(1.77μM vs.1.84μM). | Guanglei Li Yao Chen Fei Liu Wenhua Bi Chenxin Wang Danfeng Lu Dan Wen | 2023 | Microsystems & Nanoengineering2023，9，6： | 0 |
| 12 | Reductive ionic liquid-mediated crystallization for enhanced photovoltaic performance of Sn-based perovskite solar cells显示文摘Tin(Sn)-based perovskite solar cells(PSCs)have recently made inspiring progress,and certified power conversion efficiency(PCE)has reached impressive value of 14.8%.However,it is still challenging to realize efficient and stable 3D Sn-based PSCs due to the fast crystallization and easy Sn^(2+)oxidation of Sn-based perovskite.Herein,we reported the utilization of a reductive ionic liquid,methylamine formate(MAFa),to drive the controlled crystallization process and suppress Sn^(2+)oxidation of FASnI_(3)perovskite film.The coordination of C=O and Sn^(2+)and the hydrogen bonding of N-H···I between the MAFa and FASnI_(3)precursors are shown to be responsible for retarding the crystallization of FASnI_(3)during film-forming process,which promotes the oriented growth and reduced defect traps of the film.Moreover,the strong reducibility of–CHO groups in Fa−suppresses the oxidation of Sn^(2+)in the film.As a result,MAFa-modified 3D PSCs device could reach champion PCE of up to 8.50%,which is enhanced by 26.11%compared to the control device with PCE of 6.74%.Most importantly,the MAFa-modified device shows much improved stability compared to the control device under same conditions without encapsulation.This work adds key building blocks for further boosting the PCE and stability of Sn-based PSCs. | He Dong Chenxin Ran Wangyue Li Xin Liu Weiyin Gao Yingdong Xia Yonghua Chen Wei Huang | 2022 | Science China Chemistry2022，65，10： | 0 |
| 13 | Spatiotemporal mode-locking and dissipative solitons in multimode fiber lasers显示文摘Multimode fiber(MMF)lasers are emerging as a remarkable testbed to study nonlinear spatiotemporal physics with potential applications spanning from high energy pulse generation,precision measurement to nonlinear microscopy.The underlying mechanism for the generation of ultrashort pulses,which can be understood as a spatiotempoal dissipative soliton(STDS),in the nonlinear multimode resonators is the spatiotemporal mode-locking(STML)with simultaneous synchronization of temporal and spatial modes.In this review,we first introduce the general principles of STML,with an emphasize on the STML dynamics with large intermode dispersion.Then,we present the recent progress of STML,including measurement techniques for STML,exotic nonlinear dynamics of STDS,and mode field engineering in MMF lasers.We conclude by outlining some perspectives that may advance STML in the near future. | Bo Cao Chenxin Gao Kewei Liu Xiaosheng Xiao Changxi Yang Chengying Bao | 2023 | Light(Science & Applications)2023，12，11： | 0 |
| 14 | PRMT6 promotes tumorigenicity and cisplatin response of lung cancer through triggering 6PGD/ENO1 mediated cell metabolism显示文摘Metabolic reprogramming is a hallmark of cancer,including lung cancer.However,the exact underlying mechanism and therapeutic potential are largely unknown.Here we report that protein arginine methyltransferase 6(PRMT6)is highly expressed in lung cancer and is required for cell metabolism,tumorigenicity,and cisplatin response of lung cancer.PRMT6 regulated the oxidative pentose phosphate pathway(PPP)flux and glycolysis pathway in human lung cancer by increasing the activity of 6-phosphogluconate dehydrogenase(6PGD)and a-enolase(ENO1).Furthermore,PRMT6 methylated R324 of 6PGD to enhancing its activity;while methylation at R9 and R372 of ENO1 promotes formation of active ENO1 dimers and 2-phosphoglycerate(2-PG)binding to ENO1,respectively.Lastly,targeting PRMT6 blocked the oxidative PPP flux,glycolysis pathway,and tumor growth,as well as enhanced the antitumor effects of cisplatin in lung cancer.Together,this study demonstrates that PRMT6 acts as a posttranslational modification(PTM)regulator of glucose metabolism,which leads to the pathogenesis of lung cancer.It was proven that the PRMT6-6PGD/ENO1 regulatory axis is an important determinant of carcinogenesis and may become a promising cancer therapeutic strategy. | Mingming Sun Leilei Li Yujia Niu Yingzhi Wang Qi Yan Fei Xie Yaya Qiao Jiaqi Song Huanran Sun Zhen Li Sizhen Lai Hongkai Chang Han Zhang Jiyan Wang Chenxin Yang Huifang Zhao Junzhen Tan Yanping Li Shuangping Liu Bin Lu Min Liu Guangyao Kong Yujun Zhao Chunze Zhang Shu-Hai Lin Cheng Luo Shuai Zhang Changliang Shan | 2023 | Acta Pharmaceutica Sinica B2023，13，1： | 0 |
