Atomic-level structure and structure–property relationship in metallic glasses

YQ Cheng, E Ma - Progress in materials science, 2011 - Elsevier
The structure of metallic glasses (MGs) has been a long-standing mystery. On the one hand,
MGs are amorphous materials with no long-range structural order; on the other hand …

Structural aspects of metallic glasses

DB Miracle, T Egami, KM Flores, KF Kelton - Mrs bulletin, 2007 - cambridge.org

Interfacial dynamic length scales in the glass transition of a model freestanding polymer film and their connection to cooperative motion

RJ Lang, DS Simmons - Macromolecules, 2013 - ACS Publications
Nanoscale confinement alters the dynamics of glass-forming liquids in films of order 100 nm

How do quasicrystals grow?

AS Keys, SC Glotzer - Physical review letters, 2007 - APS
Using molecular simulations, we show that the aperiodic growth of quasicrystals is
controlled by the ability of the growing quasicrystal nucleus to incorporate kinetically trapped …
