Title

SANS studies of micellar structures from acyl-L-carnitines and their mixtures under different ratios pH

Abstract

Acyl L-Carnitines are a group of novel surfactants with attractive physical and biological properties associated with their head group charge features. This work proposes to use SANS as the unique technique to determine the size and shape of surfactant micelles as a function of surfactant concentration and the subsequent changes upon pH and ionic strength. The aim is to understand how changes in head group charge affects micellar size, shape and charge characteristics. We request 2 days of D11 or D33 beamtime to complete the proposed measurements.
