Abstract: Adsorbed polymer films on surfaces from lubricant solutions play important roles in preventing direct contacts of solid surfaces during rubbing and govern tribological behavior in nanosliding gaps. Using neutron reflectometry (NR) and self-developed vertical-objective-type ellipsometric… read more here.

Abstract: The translational diffusion of molecules dispersed into polymer matrices slows down tremendously when approaching a nonrepulsive interface. To unravel the origin of this phenomenon, we investigated the diffusion of molecular probes in the direction normal… read more here.
