Dynamics Simulations

The diffusion of longer n-alkanes (n-C8–n-C16) in silicalite was studied using molecular dynamics simulations in the temperature range of 300–400 K. A close agreement is found with previous quasi-elastic neutron scattering studies for both calculated diffusion coefficients and activation energies.

Complementary Techniques

After reviewing some of the basic measurements that characterize the study of physical properties of matter using neutron scattering and nuclear magnetic resonance (NMR), connections between information obtained in current research on fluid membranes using these two complementary techniques are explored in two major chapters. In the first, the type of information on the structure of fluid membranes obtained from coherent elastic neutron scattering is compared with that from NMR spectral characteristics. Then, the type of information obtained on dynamical properties from NMR relaxation (T1 and T2) measurements is compared with that from quasi-elastic neutron scattering. Examples of such connections are given with an emphasis on relationships between the time and distance scales intrinsic to neutron scattering and NMR.
