This $199,998 Project Grant was awarded by the National Science Foundation's Geosciences Program (CFDA 47.050) to the Carnegie Institution of Washington, doing business as the Carnegie Institution for Science, for a two-year collaborative research project. The project aims to investigate the crystal structure, melting, and crystallization of iron-sulfur (Fe-S) alloys under the extreme pressure and temperature conditions of the Earth's core. The research team, which includes scientists from...
This National Science Foundation (NSF) Project Grant award under the Geosciences program (CFDA 47.050) provides $191,614 to the University of South Florida to conduct collaborative research on the dynamic compression of iron-sulfur alloys at conditions relevant to the Earth's core. Over the two-year project period starting September 1, 2024, the research team will perform dynamic compression experiments and molecular dynamics simulations to study the crystal structure, melting, and...
This National Science Foundation project grant of $249,976 supports research at Arizona State University from August 2022 through July 2025 under the Geosciences program (CFDA 47.050). The award will fund collaborative research between experimental mineral physics and computational geodynamics to advance understanding of deep Earth processes through three key pieces. First, dynamic compression experiments will measure the spin state and structure of dense iron-bearing silicate melts. Second,...
This $300,000 Project Grant award from the National Science Foundation's (NSF) Mathematical and Physical Sciences program (CFDA 47.049) supports research to characterize recovered material from experiments that synthesized quasicrystals under high-pressure and high-temperature conditions. The research aims to provide a fundamental understanding of how and when quasicrystals nucleate and grow during these transient shock events, which could lead to discoveries of novel quasicrystal-forming alloys...
The National Science Foundation Division of Earth Sciences awarded a $641,554 Project Grant to the Carnegie Institution of Washington to support research measuring the melting curve of iron to the pressure of Earth's inner core boundary from September 1, 2021 to August 31, 2024. The research aims to strengthen fundamental knowledge of the integrated Earth system through latent-heat based measurements of the melting properties of iron at extreme pressures similar to those in Earth's deep...
This National Science Foundation Project Grant under the Geosciences program (CFDA 47.050) totaling $389,009 was awarded to the California Institute of Technology on August 1, 2022 to fund research exploring the composition of Earth's core through July 31, 2025. The awardee will apply a multi-technique approach combining synchrotron Mössbauer spectroscopy and x-ray diffraction to detect melting of iron alloys including iron-nickel and iron-nickel-silicon at pressures equivalent to Earth's...
This $575,000 Project Grant awarded by the National Science Foundation (NSF) under the Mathematical and Physical Sciences program (CFDA 47.049) supports a collaborative research effort between the University of Nevada, Reno and Oxford University in the United Kingdom. The project aims to study the properties of materials under extreme conditions, such as those found in planetary cores or high-energy industrial processes, by imaging the propagation of sound waves through the materials to...
This Project Grant award from the National Science Foundation (NSF) Division of Earth Sciences, under the NSF Geosciences program (CFDA 47.050), provides $225,000 to Michigan State University (MSU) over 2 years to conduct collaborative research on the effects of ferric iron on heat transport in Earth's mantle. The key objectives of this project are to: 1) Conduct experiments to grow mantle-relevant crystals with compositions including oxidized iron, 2) Measure the heat flow in these crystals...
This $142,686 Project Grant award from the National Science Foundation's (NSF) Mathematical and Physical Sciences program will support research at Northwestern University to investigate the mechanism behind an "abnormal columnar-to-equiaxed transition" (CET) phenomenon observed in metals processed using wire-laser directed energy deposition (DED) techniques. The research will leverage state-of-the-art synchrotron X-ray experiments and numerical simulations to study the influence of...
This National Science Foundation (NSF) Geosciences Program (CFDA 47.050) award of $308,705 to Michigan State University (MSU), with a performance period from August 1, 2024 to July 31, 2027, supports collaborative research into thin film mineral physics and its applications to understanding deep-focus earthquakes related to subduction zone plate tectonics. The project aims to carefully measure the crystal structure transformations of nano-grains of magnesium silicate (Mg2SiO4) thin films under...
