Homogeneous length scale of shear-induced multilamellar vesicles studied by dif...
Åslund, Ingrid; Medronho, Bruno; Topgaard, Daniel; Söderman, Olle; Schmidt, ClaudiaA recently developed protocol for pulsed gradient spin echo (PGSE) NMR is applied for the size determination of multilamellar vesicles (MLVs). By monitoring the self-diffusion behavior of water, the technique yields an estimate of the homogeneous length scale λhom, i.e. the maximum length scale at which there is local structural heterogeneity in a globally homogeneous material. A cross-over between local non-Ga...
How does a non-ionic hydrophobically modified telechelic polymer interact with ...
Santos, Tiago dos; Medronho, Bruno; Antunes, Filipe E.; Lindman, Björn; Miguel, MariaThe association between hydrophobically modified polyethylene glycol, HM-PEG, and non-ionic vesicles of tetraethylene glycol monododecyl ether, C12E4, was investigated. HM-PEG is in a triblock form, with an alkyl chain attached to each hydrophilic polymer-end. Such polymer structure is denoted as telechelic. The vesicle average radius was measured by self-diffusion measurements. The system exhibits both a monop...
