| 1 | Evolution of Grain Selection in Spiral Selector during Directional Solidification of Nickel-base Superalloys显示文摘The process of grain selection in the spiral selector was investigated by both a ProCAST simulation based on a cellular automaton finite element(CAFE) model and experimental confirmation.The results show that the height of starter block,the spiral diameter and initial angle play an important role in grain selection.The dimension of selector should be maintained in a stable range to optimize the grain orientation and select a single crystal efficiently.A selector which can efficiently select a single crystal had been successfully designed.Grain orientation fluctuation in the spiral part was also studied by means of the variation of thermal condition. | Xiangbin Meng Jinguo Li Tao Jin Xiaofeng Sun Changbo Sun Zhuangqi Hu | 2011 | Journal of Materials Science & Technology2011，27，2： | 15 |
| 2 | Multi-scale simulation of single crystal hollow turbine blade manufactured by liquid metal cooling process显示文摘Liquid metal cooling(LMC) process as a powerful directional solidification(DS) technique is prospectively used to manufacture single crystal(SC) turbine blades. An understanding of the temperature distribution and microstructure evolution in LMC process is required in order to improve the properties of the blades. For this reason, a multi-scale model coupling with the temperature field, grain growth and solute diffusion was established. The temperature distribution and mushy zone evolution of the hollow blade was simulated and discussed.According to the simulation results, the mushy zone might be convex and ahead of the ceramic beads at a lower withdrawal rate, while it will be concave and laggard at a higher withdrawal rate, and a uniform and horizontal mushy zone will be formed at a medium withdrawal rate. Grain growth of the blade at different withdrawal rates was also investigated. Single crystal structures were all selected out at three different withdrawal rates.Moreover, mis-orientation of the grains at 8 mm/min reached ~30°, while it was ~5° and ~15° at 10 mm/min and 12 mm/min, respectively. The model for predicting dendritic morphology was verified by corresponding experiment. Large scale for 2D dendritic distribution in the whole sections was investigated by experiment and simulation, and they presented a well agreement with each other. | Xuewei Yan Hang Zhang Ning Tang Changbo Sun Qingyan Xu Baicheng Liu | 2018 | Progress in Natural Science:Materials International2018，28，1： | 8 |

| 4 | A wireless, implantable optoelectrochemical probe for optogenetic stimulation and dopamine detection显示文摘Physical and chemical technologies have been continuously progressing advances in neuroscience research.The development of research tools for closed-loop control and monitoring neural activities in behaving animals is highly desirable.In this paper,we introduce a wirelessly operated,miniaturized microprobe system for optical interrogation and neurochemical sensing in the deep brain.Via epitaxial liftoff and transfer printing,microscale light-emitting diodes(micro-LEDs)as light sources and poly(3,4-ethylenedioxythiophene)polystyrene sulfonate(PEDOT:PSS)-coated diamond films as electrochemical sensors are vertically assembled to form implantable optoelectrochemical probes for real-time optogenetic stimulation and dopamine detection capabilities.A customized,lightweight circuit module is employed for untethered,remote signal control,and data acquisition.After the probe is injected into the ventral tegmental area(VTA)of freely behaving mice,in vivo experiments clearly demonstrate the utilities of the multifunctional optoelectrochemical microprobe system for optogenetic interference of place preferences and detection of dopamine release.The presented options for material and device integrations provide a practical route to simultaneous optical control and electrochemical sensing of complex nervous systems. | Changbo Liu Yu Zhao Xue Cai Yang Xie Taoyi Wang Dali Cheng Lizhu Li Rongfeng Li Yuping Deng He Ding Guoqing Lv Guanlei Zhao Lei Liu Guisheng Zou Meixin Feng Qian Sun Lan Yin Xing Sheng | 2020 | Microsystems & Nanoengineering2020，6，1： | 3 |
| 5 | Laser-driven plasma collider for nuclear studies显示文摘A novel method of initiating nuclear fusion reactions in a full plasma environment was suggested, and a proof-of-concept experiment was carried out with the D t D ! n t3 He reaction. In this new approach, two plasma jets generated by high-intensity lasers collide headon-head. The center-of-mass energy of the nuclei increases accordingly, and therefore, reaction products can be significantly enhanced, especially in the sub-Coulomb barrier ranges. As a result of the fusion reaction, up to 7:6 105 neutrons had been observed. This new type of ‘‘plasma collider'' could provide an innovative tool to study nuclear reactions under astrophysical conditions. | Changbo Fu Jie Bao Liming Chen Jianjun He Long Hou Liang Li Yanfei Li Yutong Li Guoqian Liao Yongjoo Rhee Yang Sun Shiwei Xu Dawei Yuan Xiaopeng Zhang Gang Zhao Jiarui Zhao Baojun Zhu Jianqiang Zhu Jie Zhang | 2015 | Science Bulletin2015，60，13： | 2 |

| 7 | Planning Environmental Impact Assessment Orienting Sustainable Development: Opportunities and Challenges显示文摘Strategic Environmental Assessment is a frontier subject in the field of Environmental Impact Assessment. In the past two decades, especially in recent years, much more importance has been attached to Strategic Environmental Assessment. The Environmental Impact Assessment Law of the P.R. China which was promulgated provides a great opportunity for the development of Planning Environmental Impact Assessment and brings great challenges for the development of traditional Project Environmental Impact Assessment and Planning Environmental Impact Assessment at the same time. In order to promote the implementation of 'The EIA Law', the inherent limitations of Project Environmental Impact Assessment must be identified sufficiently and the theory research and practice of Planning Environmental Impact Assessment should be strengthened as well. Measures should be taken currently to enforce the operation system. The authors wish to offer a few references to the progress and implementation of Planning Environmental Impact Assessment in China. | Sun Yanjun 1, Chen Xingeng 1, Bao Yun 2, Peng Xiaochun 3 & Gao Changbo 1 1.School of Environmental Science and Engineering, Sun Yat-sen University, Guangzhou 510275, China 2.

| 8 | Research on Public Participation and Information Publicity in Strategic Environmental Assessment显示文摘It has been generally recognized that strategic environmental assessment integrates environment and development into decision-making and becomes an important decision-making tool for implementing sustainable development. This paper firstly introduces the relationships of SEA, public participation(PP)and information publicity(IP),then discusses the key parts in enforcing the effective process of PP: They are the methods for how to make sufficient information open (What), when to implement PP (When), who will determinate the public (Who), and how to make the models of PP (How). Six cases are compared and analyzed. At last, ways to improve the effectiveness of PP in China is also presented. | Gao Changbo 1,2, Mo Chuangrong 1, Chen Xingeng 1, Zhang Shixi 1 & Sun Yanjun 1 1.School of Environmental Sciences and Engineering, Sun Yat-sen University, Guangzhou 510275, China 2.Guangdong Industry Technical College, Guangzhou 510300, China | 2005 | Chinese Journal of Population,Resources and Environment2005，3，4： | 0 |

| 10 | Inversion of Moho Interface in Northeastern China with Prior Information显示文摘Non-uniqueness is always,by nature,the problem we face in inversion processes,and it is caused by the phenomenon of equivalence in field,erroneous,discrete,and finite features in observation and the influence of other sources.Many authors have done lots of researches in this field in order to get more reliable outcomes,and joint inversion is a thriving one where different kinds of data are combined to derive certain information simultaneously or sequentially.One of these studies is that the prior information such as the geological,drilling and seismic data will be used as constraints,while the inversion procedure can be controlled.In this article we use a new method with the goal of better obtaining the three-dimensional density contrast interface.This prior seismic data integrated in the inversion can play a constrained role in the procedure which means that the depth of the Moho interface at the seismic location will be restricted.It thus can provide a credible result.In order to test its effect,this program is applied in a field example―derivation of Moho geometry in Northeast China. | Runhai Feng Ping Dong Liangshu Wang Bin Sun Yongjing Wu Changbo Li | 2014 | Journal of Earth Science2014，25，1： | 0 |
