报告人:郭啸风 教授





郭啸风博士,现任华盛顿州立大学化学系助理教授,华盛顿州立大学Alexandra Navrotsky实验热力学研究所—交叉学科研究组共同创办者,美国热力学研究协会Thermocon的主要创始成员。 2014年获得加州大学戴维斯分校化学博士学位;2015-2017年,在Glenn T. Seaborg奖的资助下在洛斯阿拉莫斯国家实验室进行博士后研究工作;2018年加入华盛顿州立大学化学系。 研究方向包括锕系物相、核燃料与乏燃料的热力学,核矿物与核材料在高温、高压等极端条件下的行为,以及超铀热力学。已在Proc. Natl. Acad. Sci., Adv. Mater., Chem. Mater., J. Nucl. Mater. 等期刊上发表学术论文50多篇。


High-temperature calorimetry is a powerful and sensitive technique to probe material chemistry, chemical bonds, and local structures by measuring the thermodynamic properties, such as heat capacity, heats of phase transition, heats of reaction, mixing and formation. In the field of nuclear material research, this technique is very useful for studying the thermal stability, phase diagrams, geochemical processes, material synthesis and chemical compatibility. In this talk, I will start with our recently built thermal capabilities in the Nuclear Science Center at WSU and its mission. I will then introduce the principle of high-temperature drop solution calorimetry and differential scanning calorimetry, followed by their applications to nuclear materials with examples of thermodynamic studies on several U-containing compounds related to research on nuclear fuel materials, ceramic-based waste form, and actinide-containing minerals.
