Exploring mechanisms leading to composition errors in monazite (CePO4) analysed with atom probe tomography
Tom Veret, Fabien Delaroche, Ivan Blum +6
Monazite (CePO4) is widely used in U-Th-Pb geochronology due to its reliable age determinations, although isotopic disturbances often require nanoscale investigation to better unde…

Role of defects in atom probe analysis of sol-gel silica
Gustav Eriksson, Matteo De Tullio, Francesco Carnovale +12
Silicon dioxide is a suitable material to encapsulate proteins at room temperature so that they can be analysed at the atomic level using laser-assisted atom probe tomography (La-A…

Evaporation of cations from non-conductive nano-samples using single-cycle THz pulses: an experimental and theoretical study
Matteo De Tullio, Giovanni Novi Inverardi, Michella Karam +11
This study investigates the emission of cations from silica samples by single-cycle THz pulses, focusing on the influence of pulse polarity. Negative THz pulses were found to effic…
