Rethinking the Transient Network Concept in Entangled Polymer Rheology
TL;DR: In this paper, the authors show that the Gaussian statistics of entanglement strands and the assumption that the stress arises exclusively from the change of intramolecular configuration entropy are not supported by molecular dynamics simulations of polymer melts.

Hydrocarbon Reactions in Carbon Nanotubes: Pyrolysis
TL;DR: In this paper, a reactive bond-order potential was used to model the thermal decomposition of covalent bonds in pyrolysis of eicosane (C2042) both in the gas phase and when confined to the interior of a (7,7) carbon nanotube.
