SEES Webinar on Nuclear Resonant Spectroscopy at the APS (April 14)
by Emily Padston 31 Mar '25

31 Mar '25

Hi all, We’re excited to invite you to an upcoming SEES webinar on Nuclear Resonant Spectroscopy (NRS) at the Advanced Photon Source, presented by Tom Toellner (X-Ray Science Division). Date: Monday, April 14 Time: 2–3 PM CDT Register for the Zoom link: https://urldefense.us/v3/__https://seescience.org/webinar-nuclear-resonant-… Nuclear Resonant Spectroscopy (NRS) takes advantage of low-energy nuclear resonances found in specific isotopes, such as Fe-57, to probe the local chemical environment and atomic vibrational dynamics within materials that contain these isotopes. This presentation will highlight NRS capabilities at the Advanced Photon Source and detail quantities that can be measured using this method that would be of interest to researchers in the Earth sciences. Two closely related techniques will be briefly reviewed: Nuclear Resonant Vibrational Spectroscopy (NRVS), which probes atomic dynamics, and Synchrotron Mössbauer Spectroscopy (SMS), which investigates the hyperfine interactions between electrons and nuclei. Additionally, the presentation will describe a new spectrometer currently under development that will enable SMS with a 1 µm focus for Fe-containing samples. We hope to see you there! Feel free to share this with anyone who might be interested. Best, Emily Emily Padston, PhD Associate Director for Education, Outreach, and Community Engagement NSF SEES – Synchrotron Earth and Environmental Science

We encourage you to join us at the June 2025 Interior of the Earth Gordon Research Conference and Gordon Research Seminar! *Deadlines:* *March 16, 2025:* Grad students and post-docs who wish to be considered for financial support should apply by March 16. March 16 is also the deadline to be considered for a talk at the Gordon Research Seminar. Details below. *May 25, 2025: *Applications will be open until May 25, unless the meetings fill earlier. However, we encourage you to apply now to secure your preferred housing. The 2025 Interior of the Earth Gordon Research Conference (GRC) will be held on June 22-27 at Mount Holyoke College (South Hadley, Massachusetts, US). Our meeting theme is Volatiles, Melt and Viscosity: Consequences for Mantle Evolution and Climate System Interactions. Researchers at all career stages are encouraged to participate. The 2025 GRC will focus on volatiles, mantle melting processes, mantle viscosity and their consequences for the dynamics and evolution of the Earth’s interior and its interactions with the climate system. The meeting will explore the distribution of volatiles inside the Earth; their impacts on the production of partial melt and on mantle rheology; and their roles in the plate tectonic system (including volatile cycling in subduction zones), volcanic processes, metasomatic alteration of the lithosphere, mantle convection, and the evolution of Earth’s interior since its formation. We will also examine the processes that dominate the cycling of volatiles between the Earth’s interior and the atmosphere, both in the recent plate tectonic regime and billions of years ago. Another key topic is the role of mantle viscosity in determining the solid Earth response to the changing mass loads of ice sheets and sea-level. The 2025 Interior of the Earth GRC will explore the latest developments in understanding these fascinating and interwoven processes by integrating wide-ranging perspectives, including geochemistry, petrology, geodynamics, seismology, geodesy, magnetotellurics, rock deformation, mineral physics, paleomagnetism, geology, and more. We have a terrific international line-up of speakers and discussion leaders for morning and evening plenary sessions, which will include ample time for discussion. Everyone will have the chance to present their work in highly interactive poster sessions. Unscheduled afternoon time will provide opportunities for informal discussions that can lead to new collaborations and projects. The small meeting size (typically 130-140 people) will help to create a sense of community and enhance interactions between scientists from all career stages. *For the GRC meeting program and how to apply, please visit this page: https://urldefense.us/v3/__https://www.grc.org/interior-of-the-earth-confer… <https://urldefense.us/v3/__https://www.grc.org/interior-of-the-earth-confer… >.* Early Career Researchers: The 2025 Interior of the Earth Gordon Research Seminar (GRS) will be held on June 21-22, also at Mount Holyoke College, and its theme is Coupled Surface-Interior Interactions: The Role of Volatiles in Subduction and Eruption Processes.

Levitas Departments of Aerospace and Mechanical Engineering Iowa State University Date: Thursday, March 6, 2025 at 12 p.m. ET / 9 a.m. PT Preregister and Receive Zoom<https://urldefense.us/v3/__https://info.aps.org/e/640833/sBTKqoEXqF--1JVQ--… > Abstract Plastic strain-induced phase transformations (PTs) during compression in diamond anvil cell (DAC) and torsion in rotational DAC (RDAC) require entirely different thermodynamic and kinetic treatments and experimental characterization [1,2] than pressure-induced PTs. The four-scale theory for plastic strain-induced PTs is developed [1], including molecular dynamics and first-principle simulations, developed nanoscale and scale-free phase-field approaches, and the behavior of the sample in DAC/RDAC at the macroscale. Various experimental effects are reproduced and predicted. It became clear [2-4] that their description strongly depends on the microstructure and its evolution, and microstructure evolves during strain-induced PTs. Four topics will be covered. 1. It was found [3,4] for severely predeformed Zr that (a) crystallite size and dislocation density in both phases in a single-phase state, the minimum pressure for the strain-induced α-ω PT in Zr, and the pressure-dependent yield strength of ω-Zr are getting steady and independent of plastic strain tensor and strain path ; (b) crystallite size and dislocation density in ω-Zr and (with some outliners) α-Zr during PT are independent of pressure, plastic strain tensor, and its path, and depend on the volume fraction of the high-pressure phase only. Obtained results can be used to find economic ways of grain refinement during PT and obtain nanocomposite with optimal properties. 2. Coupled experimental-analytical-computational approaches, utilizing synchrotron X-ray diffraction, are developed [5,6] to solve an inverse problem and find fields of all components of stress and plastic strain tensors and friction rules before, during, and after α-ω PT in strongly plastically predeformed Zr. In addition, the kinetics of strain-induced PT is described in the whole sample. 3. We revealed in situ various unexpected plastic strain-induced PT phenomena in Si [7]. Thus, for 100 nm Si, strain-induced PT Si-I→Si-II initiates at 0.3 GPa versus 16.2 GPa under hydrostatic conditions; for 30 nm Si, it is 6.1 GPa versus ∞ since it does not occur. For 100 nm Si-I→Si-III, it is 0.6 GPa vs. ∞. The predicted theoretical correlation between the direct and inverse Hall-Petch effect of the grain size on the yield strength and the minimum pressure for strain-induced PT is confirmed. Retaining Si-II at ambient pressure and obtaining reverse Si-II→Si-I PT are achieved for the first time. Retaining single-phase Si III is achieved at much more economic conditions than the currently known. 4. A new theory is developed for the plastic strain-induced olivine-spinel PT in a shear band, which resolves multiple existing puzzles in the mechanism of deep-focus earthquakes [8]. Conceptual experimental confirmation is obtained [9]. The obtained results offer a new fundamental understanding of strain-induced PTs under high pressure in DAC/RDAC. They create new opportunities in material design, synthesis, and processing of nanostructured materials by severe plastic deformations at low pressure, methods of controlling PTs and nanostructures, and searching for new high-pressure phases and phenomena. 1.
