Published in 2019 at "Surfaces and Interfaces"

DOI: 10.1016/j.surfin.2019.100378

Abstract: Abstract High-vacuum XPS have been used to analyse the surface modification of a 3 nm-thick Sn thin film on Si (100) before and after annealing up to 450 °C. Increasing the XPS stage temperature led to a… read more here.

Published in 2017 at "Scientific Reports"

DOI: 10.1038/s41598-017-04337-w

Abstract: A micro-boat self-propelled by a camphor engine, carrying seed crystals of FeCl3, promoted the evolution of chemical gardens when placed on the surface of aqueous solutions of potassium hexacyanoferrate. Inverse chemical gardens (growing from the… read more here.

Published in 2021 at "Monthly Notices of the Royal Astronomical Society"

DOI: 10.1093/mnras/stab1018

Abstract: We apply fossil record techniques to the CALIFA sample to study how galaxies in the Local Universe have evolved in terms of their chemical content. We show how the stellar metallicity and the mass–metallicity relation… read more here.
