US-France Cooperative Research: Study of the Liquid Immiscibility of Core Materials at High Pressure and Temperature

0338442Fei 这个为期两年的奖项支持美法合作研究地核高压和高温下材料的液体不混溶性的演化。 华盛顿卡内基研究所的美国研究员费英伟和巴黎皮埃尔和玛丽居里大学的法国研究员克里斯特尔·桑卢普将通过多砧实验，通过原位测量液体的密度和结构来研究铁系统。 现场测量将在法国格勒诺布尔的欧洲同步辐射设施（ESRF）进行。拟议的研究旨在了解地球的分化及其液体核心的成分和结构。 研究结果将增进对磁场起源的理解，并影响岩石学、矿物物理学、地球化学、地震学和地球动力学研究。 该项目利用了法国独特的设施和法国研究人员使用的 X 射线技术。美国国家科学基金会 (NSF) 和国家科学研究中心 (CNRS) 共同支持该项目。 美国国家科学基金会为美国调查员访问法国提供资金。 CNRS 将承担法国调查员前往美国的费用。

0338442FeiThis two-year award supports U.S.-France cooperative research on the evolution of liquid immiscibility of materials at high pressure and temperature in the Earth's core. The U.S. investigator, Yingwei Fei of the Carnegie Institution of Washington, and French investigator, Chrystele Sanloup of the Universite Pierre et Marie Curie in Paris, will investigate iron systems through multi-anvil experiments by in situ measurements of density and structure of liquids. The in situ measurements will take place at the European Synchrotron Radiation Facility (ESRF) in Grenoble, France. The proposed research is aimed at understanding differentiation of the Earth and the composition and structure of its liquid core. The results will advance understanding on the origin of the magnetic field and impact research in petrology, mineral physics, geochemistry, seismology and geodynamics. The project takes advantage of access to unique facilities in France and x-ray techniques utilized by the French investigator.The National Science Foundation (NSF) and the Centre National de la Recherche Scientifique (CNRS) jointly support this project. NSF provides funding for visits to France by the U.S. investigator. The CNRS will cover the costs of the French investigator's travel to the United States.
