E-mail: [email protected] The Terebelliformia (sensu Rouse and Pleijel 2001) is a group of sedentary polychaetes comprising the families Terebellidae, Ampharetidae, Alvinellidae, and Pectiinaridae. Within the taxon Terebelliformia, the family Terebellidae contains more than 400 species grouped in approximately 60 genera withi...

We have studied the chain dynamics of poly(ethylene-alt-propylene) by combining neutron spin echo experiments and fully atomistic molecular dynamics simulations. We have focussed on molecular weights of the order of two times the entanglement mass, for which, in principle, the topological constraints are not important and the chain dynamics should be well described †UPV/EHU ‡CSIC-UPV/EHU ¶Forsc...

The localization kinetics of a regular block-copolymer of total length N and block size M at a selective liquid-liquid interface is studied in the limit of strong segregation between hydrophobic and polar segments in the chain. We propose a simple analytic theory based on scaling arguments which describes the relaxation of the initial coil into a flat-shaped layer for the cases of both Rouse an...

By means of computer simulations, we investigate the relaxation of the Rouse modes in a simple bead-spring model for non-entangled polymer blends. Two different models are used for the fast component, namely fully flexible and semiflexible chains. The latter, which incorporate intramolecular barriers with bending and torsion terms, are semiflexible in the sense that static intrachain correlatio...
