To efficiently capture the energy of the nuclear bond, advanced nuclear reactor concepts
seek solid fuels that must withstand unprecedented temperature and radiation extremes. In …

This review addresses new developments in the emerging area of “atom probe
crystallography”, a materials characterization tool with the unique capacity to reveal both …

The addition of pulsed lasers to atom probe tomography (APT) extends its high spatial and
mass resolution capability to nonconducting materials, such as oxides. For a prototypical …

The processes by which field evaporation in an atom probe is momentarily stimulated by
impingement of a laser beam on a specimen are considered. For metals, the dominant and …

After reviewing the physics and chemistry in high electrostatic fields and summarizing the
theoretical results for Atom Probe Tomography of metallic tips, we turn to the new challenges …

Abstract Atom Probe Tomography (APT) and Transmission Electron Microscopy (TEM) are
combined for examining α-case formation in Ti-6Al-4V, generated by air exposure at 800° C …

Atom probe tomography (APT) can theoretically deliver accurate chemical and isotopic
analyses at a high level of sensitivity, precision, and spatial resolution. However, empirical …

Atom probe tomography, APT, is the only microstructural method that can routinely analyse
and position individual atoms in a material with a spatial resolution of 0.1–0.5 nm. Recent …

Due to the intrinsic evaporation properties of the material studied, insufficient mass-resolving
power and lack of knowledge of the kinetic energy of incident ions, peaks in the atom probe …

Xenotime (YPO4) is an accessory phase common in low to high‐temperature geological
environments. Xenotime is an established geochronometer, though its small size, low modal …
