TL;DR: In this article, the authors studied the response of a C100H202 model polyethylene melt to a step change from equilibrium to a constant, high shear rate flow and found that transient shear stress exhibits pronounced overshoot at the strain value predicted by the reptation model, in striking similarity to melts of longer, entangled polymer governed by reptation motion.

TL;DR: It is found that a discretized version of Alt’s model produces solutions similar to the continuous model, even at very coarse discretization, suggesting that the simple and easy-to-use Rivero et al. model is adequate for modeling bacterial behavior within the parameter ranges investigated.

TL;DR: In this paper, the impact of physisorbing adsorbates on the structural and mechanical evolution of gold nanowires undergoing elongation was studied using molecular dynamics simulations, with various models giving rise to a different surface coverage and mobility of the adsorbed phase.

TL;DR: In this article, the authors examined molecular junctions composed of benzene-1,4-dithiolate bonded between gold nanotips, focusing on the importance of environmental factors and interelectrode distance on the formation and structure of bridged molecules.
