Abstract

SHS investigation development is considered from the geographical and historical viewpoint. 3 stages are described. Within Stage 1 the work was carried out in the Department of the Institute of Chemical Physics in Chernogolovka where the scientific discovery had been made. At Stage 2 the interest to SHS arose in different cities and towns of the former USSR. Within Stage 3 SHS entered the international scene. Now SHS processes and products are being studied in more than 50 countries.

Abstract

Biological membranes are complex multicomponent systems whose dynamics and structure provide their physiological function. Many parameters interplay to determine the membrane flexibility; among them, lipid composition, lipid-protein interaction, hydration, temperature etc.

We provide here a tentative overview of recent successful neutron scattering experiments on different oriented model membranes, with the aim to demonstrate the many unique advantages that elastic and quasi-elastic neutron scattering offer for the investigation of membrane dynamics.
