Specimen preparation for atom probe tomography analysis of complex multifunctional nanoparticles and nanostructures: state-of-the-art and challenges
Varatharaja Nallathambi, Se-Ho Kim, Nikita Polin +4
Atom probe tomography (APT) provides the three-dimensional composition of materials at near-atomic length scales, achieving detection limits in the range of tens of atomic parts-pe…
Spatially resolving superconductivity in type-II superconductors
Donald M. Evans, Michele Conroy, Lukas Puntigam +6
Superconductivity is identified by the emergence of a macroscopic zero-resistance state, typically inferred from a vanishing four-probe voltage at finite current. That inference as…
Kinetically controlling surface atom arrangements in thermally robust, amorphous high-entropy alloy nanoparticles by solvent selection
Varatharaja Nallathambi, Se-Ho Kim, Baptiste Gault +3
The ability to tailor nanoscale surface atom arrangements through multi-elemental compositional control provides high-entropy nanoalloys with promising functional properties. Devel…
Machine learning enhanced atom probe tomography analysis: a snapshot review
Yue Li, Ye Wei, Alaukik Saxena +3
Atom probe tomography (APT) is a burgeoning characterization technique that provides compositional mapping of materials in three-dimensions at near-atomic scale. Since its signific…
Advancing atom probe tomography capabilities to understand bone microstructures at the near-atomic scale
Tim M. Schwarz, Maïtena Dumont, Victoria Garcia-Giner +3
Bone structure is generally hierarchically organized into organic (collagen, proteins,...), inorganic (hydroxyapatite (HAP)) components. However, many fundamental mechanisms of the…
Kinetics and direct imaging of electrochemically formed palladium hydride for efficient hydrogen evolution reaction
Luca Camuti, Se-Ho Kim, Filip Podjaski +8
Active and reliable electrocatalysts are fundamental to renewable energy technologies. PdCoO2 has recently been recognized as a promising catalyst template for the hydrogen evoluti…
