Metallurgy at the nanoscale: domain walls in nanoalloys
Grégoire Breyton, Hakim Amara, Jaysen Nelayah +8
In binary alloys, domain walls play a central role not only on the phase transitions but also on their physical properties and were at the heart of the 70's metallurgy research. Wh…

A deep learning approach for determining the chiral indices of carbon nanotubes from high-resolution transmission electron microscopy images
G. D. Förster, A. Castan, A. Loiseau +5
Chiral indices determine important properties of carbon nanotubes (CNTs). Unfortunately, their determination from high-resolution transmission electron microscopy (HRTEM) images, t…
