These observations suggest that changes in the properties of polymer chains at the nanoscale level related to interfacial interactions, have a finite lifetime and that the deviations from bulk behaviour correspond to metastable states, that is, polymer conformations associated with local and not global minima of the free energy.
Unveiling the mechanisms behind the response of polymers on annealing has both scientific and practical significance. From the scientific point of view, understanding the nature of the mechanisms behind the evolution ofin different annealing conditions could finally lead to a detailed understanding of the behaviour of macromolecules in confined geometries.
. This effect is reflected in the thickness dependence of the structural relaxation process, as probed by dielectric spectroscopy. Regardless of whether thinner films exhibit a higher or lowerɛ

Dynamic spatiotemporal determinants modulate GPCR:G protein coupling selectivity and promiscuity - Nature CommunicationsG protein coupled receptors (GPCRs) can couple to different Gα protein subfamilies either selectively or promiscuously. Here, the authors use computational approach to show that selectivity determinants are at the periphery of the GPCR—G protein interface and that promiscuous GPCRs more frequently sample the common rather than selective contacts.
