Astrobiology Cosmochemistry Extreme Materials

 

Suzy Vitale operates Carnegie's new, state-of-the-art FEI Helios PFIB G4, and the Zeiss Auriga SEM. Suzy's expertise is in TEM sample preparation, particularly in powder/particle materials, and also has a strong background in 3D imaging and analysis, high-resolution imaging, EBSD, and qualitative EDS. Suzy trains and mentors new and visiting users and collaborates with staff and postdocs on research projects.

Additionally, she, along with Electron Microprobe Lab Manager Emma Bullock, provides leadership to maintain and manage the smooth operation of the Electron Microscopy Suite. Before joining the Geophysical Laboratory, Suzy ran the FIB/SEM lab at Sandia National Laboratories, a materials characterization laboratory. There, she imaged, FIB'ed, and characterized a wide variety of materials, including polymers, ceramics, metals, metal alloys, composites, and metal-organic frameworks.

Abstract
With the advent of toroidal and double-stage diamond anvil cells (DACs), pressures between 4 and 10 Mbar can be achieved under static compression, however, the ability to explore diverse sample assemblies is limited on these micron-scale anvils. Adapting the toroidal DAC to support larger sample volumes offers expanded capabilities in physics, chemistry, and planetary science: including, characterizing materials in soft pressure media to multi-megabar pressures, synthesizing novel phases, and probing planetary assemblages at the interior pressures and temperatures of super-Earths and sub-Neptunes. Here we have continued the exploration of larger toroidal DAC profiles by iteratively testing various torus and shoulder depths with central culet diameters in the 30-50 mu m range. We present a 30 mu m culet profile that reached a maximum pressure of 414(1) GPa based on a Pt scale. The 300 K equations of state fit to our P-V data collected on gold and rhenium are compatible with extrapolated hydrostatic equations of state within 1% up to 4 Mbar. This work validates the performance of these large-culet toroidal anvils to > 4 Mbar and provides a promising foundation to develop toroidal DACs for diverse sample loading and laser heating.

Abstract
When diamond anvil cell (DAC) sample chambers are outfitted with both thermal insulation and electrodes, two cutting-edge experimental methods are enabled: Joule heating with spectroradiometric temperature measurement and electrical resistance measurements of samples heated to thousands of kelvin. The accuracy of temperature and resistance measurements, however, often suffers from poor control of the shape and location of the sample, electrodes, and thermal insulation. Here, we present a recipe for the reproducible and precise fabrication of DAC sample, electrodes, and thermal insulation using a three-layer microassembly. The microassembly contains two potassium chloride thermal insulation layers, four electrical leads, a sample, and a buttressing layer made of polycrystalline alumina. The sample, innermost electrodes, and buttress layer are fabricated by focused-ion-beam milling. Three iron samples are presented as proof of concept. Each is successfully compressed and pulsed Joule heated while maintaining a four-point probe configuration. The highest pressure-temperature condition achieved is similar to 150 GPa and 4000 K.
