Predicting the Glass Transition Temperature of Biopolymers via High-Throughput Molecular Dynamics Simulations and Machine Learning [PDF]
, 2023 Nature has only provided us with a limited number of bio-based and biodegradable building blocks. Therefore, the fine tuning of the sustainable polymer properties is expected to be achieved through the control of the composition of bio-based copolymers ...

Molecular Signatures of the Glass Transition in Polymers [PDF]
, 2022 The glass transition temperature (Tg) is one of the most fundamental properties of polymers. Tg is predicted as a sudden change in a “macroscopic” quantity (e.g. compressibility).

Second-order Phase Transition Behavior behind Polymer Glass Transition [PDF]
, 2022 Glass transition has similarity to the second-order phase transition in temperature dependent changes in entropy, non-Arrhenius viscosity, and heat capacity of glass forming materials. However, it has primarily been considered to be not phase transition.

Electron anions and the glass transition temperature [PDF]
Proceedings of the National Academy of Sciences, 2016 Significance Electrides are ionic materials in which electrons act as anions. Solvated electrons in ammonia are one of the early known examples of such anions in liquids. Electron anions in crystalline materials have previously been shown to dramatically alter their electronic properties, for example, to turn an insulator into a ...

Temperature dependence of the interfacial shear strength in glass-fibre epoxy composites [PDF]
, 2014 The present work focuses on further investigation of the hypothesis that a significant fraction of apparent interfacial shear strength (IFSS) in fibre-reinforced composites can be attributed to a combination of residual radial compressive stress and ...
