Combined small-angle x-ray and neutron scattering experiments for thickness characterization of ganglioside bilayers
Article Abstract:
A study was conducted to analyze dilute solutions of the ganglioside GM3 in water using small-angle neutron and x-ray scattering techniques. The ganglioside was prepared as sodium salt. Two different wavelengths were utilized to carry out experiments of small-angle neutron scattering. In addition, the Huxley-Holmes camera was used to perform small-angle x-ray scattering. Results indicated thickness fluctuations originating from the mismatch between headgroup and chains lateral hindrances.

Experimental evidence of the electrostatic contribution to the bending rigidity of charged membranes
Article Abstract:
The issue of the origin of the bending rigidity of a charged membrane formed from amphiphilic molecules is addressed. Electrostatic effects are investigated by direct measurement of the force that is required for deforming a catanionic membrane as function of the ionic strength of the medium by means of an atomic force microscope.

Phase transitions of individually addressable microstructured membranes visualized by imaging ellipsometry
Article Abstract:
The imaging ellipsometry technique is employed to study the phase transitions of various individually addressable microstructured membranes. Microstructured bilayers seem to offer the unique advantage of integrating an internal standard of known thermotropic properties.
