| 1 | 3-79 Live Cell Imaging Study of XRCC1 Kinetics at the显示文摘DNA strand breaks can lead to cell carcinogenesis or cell death if not repaired rapidly and efficiently. An online live cell imaging system was established at the high energy microbeam facility at the Institute of Modern Physics (IMP) to study early and fast cellular response to DNA damage after high linear energy transfer (LET) ion radiation. HT1080 cells expressing XRCC1-RFP were irradiated with single high energy nickel ions, and time-lapse images of the irradiated cells were obtained online. | Du Guanghua Liu Wenjing Guo Jinlong Chen Hao Wu Ruqun Wei Junzhe Guo Na | 2015 | IMP & HIRFL Annual Report2015，，1： | 0 |

However, providing a suitable environment to keep cells heathy is still a challenge in live cell imaging experiments, and has great influence on the reliability of the experimental results. Many factors are needed to maintain cells healthy, such as temperature, pH, oxygen tension, CO2 and so on. | Liu Wenjing Guo Jinlong Wu Ruqun Chen Hao Wei Junzhe Du Guanghua | 2015 | IMP & HIRFL Annual Report2015，，1： | 0 |

| 4 | 3-84 Preliminary Tests for Fabrication of Single Free-standing Nanowire显示文摘Free-standing single nanowire with individual microelectrode shows potential for bio-probing and photoelectrochemical study. Several methods have been reported to fabricate this kind of nanostructure, such as AFM combined lithography technology and VLS-CVD method[1;2]. However, most of the present methods focus on fabricating semiconductor nanowires and are not very appropriate for metallic nanowires. In view of the facts, we propose a new approach for assembly of metallic nanowires. | Guo Jinlong Du Guanghua Wei Junzhe Wu Ruqun Liu Wenjing Chen Hao | 2015 | IMP & HIRFL Annual Report2015，，1： | 0 |
| 5 | Strong metal–support interaction boosts the electrocatalytic hydrogen evolution capability of Ru nanoparticles supported on titanium nitride显示文摘Ruthenium(Ru)has been regarded as one of the most promising alternatives to substitute Pt for catalyzing alkaline hydrogen evolution reaction(HER),owing to its inherent high activity and being the cheapest platinum-group metal.Herein,based on the idea of strong metal–support interaction(SMSI)regulation,Ru/TiN catalysts with different degrees of TiN overlayer over Ru nanoparticles were fabricated,which were applied to the alkaline electrolytic water.Characterizations reveal that the TiN overlayer would gradually encapsulate the Ru nanoparticles and induce more electron transfer from Ru nanoparticles to TiN support by the Ru–N–Ti bond as the SMSI degree increased.Further study shows that the exposed Ru–TiN interfaces greatly promote the H_(2) desorption capacity.Thus,the Ru/TiN-300 with a moderate SMSI degree exhibits excellent HER performance,with an overpotential of 38 mV at 10 mA cm^(−2).Also,due to the encapsulation role of TiN overlayer on Ru nanoparticles,it displays super long-term stability with a very slight potential change after 24 h.This study provides a deep insight into the influence of the SMSI effect between Ru and TiN on HER and offers a novel approach for preparing efficient and stable HER electrocatalysts through SMSI engineering. | Xin Wang Xiaoli Yang Guangxian Pei Jifa Yang Junzhe Liu Fengwang Zhao Fayi Jin Wei Jiang Haoxi Ben Lixue Zhang | 2024 | Carbon Energy2024，6，1： | 0 |

| 9 | 4-70 Efficiency of Dyes in STORM Influences the Result of Dual Color Experiment显示文摘Stochastic Optical Reconstruction Microscopy(STORM)is one of the super-resolution microscopy,which pro-vides resolutions down to a few tens of nanometers by exploiting the cycling of dyes between uorescent and nonuorescent states to obtain a sparse population of emitters and precisely localizing them individually[1].The key material is the uorescent dyes are photo-switchable thousands of times before they turn quenched completely.Fluorescent proteins and organic dyes are the two main kinds of uorescent dyes in the experiment[2].The former are widely used in the living cell,the latter are used in the xed cells in the form of single dye or dye pair[3]. | Wu Ruqun Du Guanghua Liu Wenjing Guo Jinlong Chen Hao Wei Junzhe Li Yaning Zhao Jing Li Xiaoyue | 2016 | IMP & HIRFL Annual Report2016，，1： | 0 |

| 13 | Immobilized ZnO based nanostructures and their environmental applications显示文摘In the research of semiconductor metal oxides,zinc oxide(ZnO)nanomaterials have been committed to design and exploration because of their unique physical and chemical properties.ZnO has many structural characteristics and has considerable practical applications in the field of environmental technology.However,ZnO nanomaterials used for environmental functions are often presented in the form of powders.After use,they need to go through recovery processes such as centrifugation and filtration,which is also easy to cause secondary pollution.The above problems can be avoided by fixing ZnO nanostructures on substrates to form easily movable materials.Here,we present a review of our work and some others on the different synthetic strategies,formation mechanism,modification,performance and diversifications of immobilized ZnO based nanostructures,and highlight their photocatalytic related activities for environmental remediation.Various immobilized ZnO based nanostructures including nanorod arrays,3D nanostructures,and composite heterostructures have been focused.We hope it may serve as a useful reference for researchers interested in immobilized semiconductor nanostructures and their photocatalysis and other environmental applications. | Wei Gao Yangsi Liu Junzhe Dong | 2021 | Progress in Natural Science:Materials International2021，31，6： | 0 |
