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.

0338442 Fei这个两年的奖项支持美国-法国合作研究地核内材料在高温高压下的液体不渗透性的演变。 美国研究员、华盛顿卡内基研究所的费英伟和法国研究员、巴黎皮埃尔和玛丽·居里大学的克里斯泰尔·桑卢普将通过多砧实验，通过现场测量液体的密度和结构，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核的组成和结构。 研究结果将促进对磁场起源的理解，并将影响岩石学、矿物物理学、地球化学、地震学和地球动力学的研究。 该项目利用了法国独特的设施和法国调查人员使用的X射线技术，国家科学基金会和国家科学研究中心共同支持该项目。 NSF为美国调查员访问法国提供资金。 法国国家科学研究中心将支付法国调查员前往美国的旅费。
