DESCRIPTION:Speakers: Karen Edler (University of Bath)\nThe self-assembly 
 of surfactant micelles is important in many applications from controlling 
 the rheology and cleaning properties of personal care products to templati
 ng pore\nstructures in inorganic materials. The size and shape of cationic
  micelles can be controlled via their interaction with their soluble count
 er-anions\, and this is well known to affect properties such as the critic
 al micelle concentration. However\, although the bulk properties of such s
 olutions have been studied using a range of techniques including conductiv
 ity and small angle scattering\, it is difficult to directly measure the i
 nteractions between the surfactant headgroups and ions in solution. Much o
 f the literature description of these systems is therefore inferred from t
 hese bulk measurements. We have used wide angle neutron scattering on solu
 tions of decyltrimethylammonium cations\, which have been ion exchanged to
  contain a range of counteranions\, along the Hofmeister series\, to direc
 tly probe interactions in these systems. The data was modelled using Empir
 ical Potential Structure Refinement (EPSR) to study the association betwee
 n the different counterions and the micelle surfaces and how this affects 
 micellar structures in these systems.\n\nhttps://lindico453.srv.lu.se/even
