Dynamic relaxations and relaxation-property relationships in metallic glasses

WH Wang - Progress in Materials Science, 2019 - Elsevier
Dynamic relaxation is an intrinsic and universal feature of glasses and enables fluctuation
and dissipation to occur, which induces plentiful behaviour, maintains equilibrium, and …

Growing length scales and their relation to timescales in glass-forming liquids

S Karmakar, C Dasgupta, S Sastry - Annu. Rev. Condens. Matter …, 2014 - annualreviews.org
The question of whether the dramatic slowing down of the dynamics of glass-forming liquids
near the structural glass transition is caused by the growth of one or more correlation lengths …

The relationship of dynamical heterogeneity to the Adam-Gibbs and random first-order transition theories of glass formation

FW Starr, JF Douglas, S Sastry - The Journal of chemical physics, 2013 - pubs.aip.org
We carefully examine common measures of dynamical heterogeneity for a model polymer

Polymer glass formation: Role of activation free energy, configurational entropy, and collective motion

WS Xu, JF Douglas, ZY Sun - Macromolecules, 2021 - ACS Publications
We provide a perspective on polymer glass formation, with an emphasis on models in which
