Nanoscale mapping of phase-transformation pathways in medium-Mn TRIP steel by multimodal STEM
Marc Raventós-Tato, S. Leila Panahi, Núria Bagués +4
The mechanical response of third-generation advanced high-strength steels is governed by phase transformations at the nanoscale, yet the coupled evolution of chemistry and crystall…
Unveiling the local elemental arrangements across the interfaces inside CdSe/Cd1-xZnxS core-shell and CdSe/CdS/ Cd1-xZnxS core-crown-shell quantum wells
Tatiana Lastovina, Oleg Usoltsev, Furkan Isik +4
We report on a systematic study of the Cd, Zn, Se, and S elemental distributions across the interfaces in CdSe/Cd1-xZnxS core-shell and CdSe/CdS/Cd1-xZnxS core-crown-shell quantum…
Nonlinear atomic vibrations and structural phase transitions in strained carbon chains
G. M. Chechin, D. A. Sizintsev, O. A. Usoltsev
We consider longitudinal nonlinear atomic vibrations in uniformly strained carbon chains with the cumulene structure (. With the aid of ab initio simulations, based on…
Properties of π-mode vibrations in strained carbon chains
G. M. Chechin, D. A. Sizintsev, O. A. Usoltsev
Nonlinear vibrations in strained monoatomic carbon chains are studied with the aid of ab initio methods based on the density functional theory. An unexpected phenomenon of structur…
