Three-dimensional atomic mapping of ligands on palladium nanoparticles by atom probe tomography. [PDF]
Nat Commun, 2021 Despite the important role of ligands in designing nanoparticles, directly imaging them on the nanoparticle surface remains a challenge. Here, the authors use atom probe tomography to map the spatial distribution of ligands on nanoparticles and reveal ...

Spatial Resolution in Atom Probe Tomography [PDF]
Microscopy and Microanalysis, 2010 AbstractThis article addresses gaps in definitions and a lack of standard measurement techniques to assess the spatial resolution in atom probe tomography. This resolution is known to be anisotropic, being better in-depth than laterally. Generally the presence of atomic planes in the tomographic reconstruction is considered as being a sufficient proof ...

Atom Probe Tomography Analysis of Mica
Microscopy and Microanalysis, 2022 AbstractLaser-assisted atom probe tomography (APT) is a relatively new, powerful technique for sub-nanometric mineral and biomineral analysis. However, the laser-assisted APT analysis of highly anisotropic and chemically diverse minerals, such as phyllosilicates, may prove especially challenging due to the complex interaction between the crystal ...
