为追踪环境生态学研究热点与学术前沿动态，增进青年学者间学术交流，促进不同学科及研究方向之间交叉融合，提升青年学者科研水平，研究院将开展由青年学者共同组织参与的“环境生态专题青年学者沙龙”月度学术活动。青年学者沙龙面向研究院青年教师、博士后和博士，每期活动由1-2位青年教师主持，2-3位特邀嘉宾或青年科研人员做主题报告，分享研究进展与心得，并与参与学者互动交流。活动秉持自愿参加的原则，采用开放式分享和讨论的模式，诚邀研究院广大青年科研人员积极参与，享受学术盛宴，激发创新灵感，寻求原创突破。所涉及的主题包括但不限于流域/湿地生态规划与管理、湿地保护与修复、可持续环境与资源管理、水环境过程与水生态效应、水质净化与安全保障、水污染控制原理及技术等研究方向。

青年学者沙龙（第一期）具体安排如下：

活动时间：2019年10月25日11：00-14：00

活动地点：科技北楼503A会议室

活动福利：提供午餐、水果、饮品等

活动主持人：何頔 教授

报告题目1：Green rust formation induced by reaction between aqueous Fe(II) and smectite clay minerals

报告人1简介：Dr Richard Collins,Senior Lecturer in the School of Civil and Environmental Engineering,University of New South Wales (UNSW) Australia. Dr Richard Collins obtained his PhD in soil chemistry from the University of Adelaide in 2002. He then spent 3 years working at the French Atomic Energy Commission in Saclay, France where he conducted research on the bioavailability, toxicity and speciation of elements of interest in the nuclear fuel cycle. In 2005 he commenced working at UNSW Sydney. Since that time, he has worked on a range of research topics of both applied and fundamental importance, such as acid sulfate soil remediation, uranium immobilisation, iron oxide transformations and zero valent iron reactions. A lot of this research has a strong focus on iron redox processes relevant to natural and engineered environments. He is an expert user of X-ray absorption spectroscopy methods and analyses and has used a wide range of synchrotrons in Australia, USA, Japan, Taiwan and France. During his time at UNSW he has been awarded an Australian Research Council Future Fellowship, Australian-American Fulbright Fellowship in Nuclear Science and Technology, Invitational Fellowship from the Japan Society for the Promotion of Science and is currently a UNSW Scientia Fellow. Over the last 10 years he has contributed to obtaining ~$6.5 M AUD in competitive research funding and has published about 75 refereed journal articles and 20 industry reports.

报告题目2：Impacts of Fe(II) andphosphate on the redox reactions between iron oxides and aqueous sulfide

报告人2简介：Dr.ShaojianZhang,postdoctoral research fellow in the Institute of Environmental and Ecological Engineering, Guangdong University of Technology (GDUT). Dr. Zhang obtained his PhD degree in geoscience from University Tübingen (Germany) in 2019.During his PhD study, he investigated the redox reactions between goethite and aqueous sulfide in the presence of aqueous Fe(II) and dissolved natural organic matter (NOM), with the finding of the inhibitory effect of surface associated Fe(II) and NOM on goethite sulfidation. He also proposed the oxidizing capability and mechanisms of Fe(III) species at goethite surface in the presence of aqueous Fe(II). In GDUT,hisresearch concerns iron-mediated remediation of water contaminants, focusing on the mobilization of phosphate under the influence of iron-containing minerals sulfidation.
