On the quenching of MLCT(sub Re->bpy) luminescence by Cu(II) species in Re(I) polymer micelles
Article Abstract:
Transmission electron microscopy images and dynamic light scattering experiments are demonstrated to show that Re-(polystyrene-block-poly(4-vinylpyridine) (Re-P4VP) polymers aggregate to form mainly spherical micelles whose dimensions are in the range of 90-430 nm. After the coordination of Cu(II) species to the Re(1) polymer, the polymer Re-P4VP-CuCl(sub 2) aggregates to form micelles that are distorted from spherical shape and whose dimensions are small than those micelles formed by the polymer Re-P4VP.

Molecular dynamics simulations of ionic interactions with dodecyl sulfate micelles
Article Abstract:
Specific ion effects on micelles are addressed by molecular dynamics simulations of Li(super +), Na(super +), and HN(sub 4)(super +) cations with dodecyl sulfate (DS) micelles in aqueous solution. The direct coordination of the ions to the headgroups requires their dehydration and shows that hydrated-ion radii are inadequate for models of the micelle interfacial region.

Implicit solvent simulations of DPC micelle formation
Article Abstract:
The aggregation number, the micelle size distribution and critical micelle concentration (CMC) are obtained with the help of molecular dynamics simulations of 960 dodecylphosphocholine (DPC) molecules at different concentrations. An aggregation number of 53-56 and a CMC of 1.25 mM are obtained at 20mM and the aggregation number increases to 90 at 100mM.
