The dynamic properties of adsorbed molecules play a central role in reactions and
separations that take place within the cavities of zeolites and other shape-selective …

The basic principles of NMR diffusion studies and a generalized approach to calculate NMR
spin echo attenuation due to diffusion in the presence of gradients of the polarizing magnetic …

Diffusion as the process of particle transport due to stochastic movement is a phenomenon
of crucial relevance for a large variety of processes and materials. This comprehensive …

Carbon nanotubes, unmodified (pristine) and modified through charged atoms, were
simulated in water, and their water conduction rates determined. The conducted water inside …

Li–Fe antisite defects are commonly found in LiFePO4 particles and can impede or block Li
diffusion in the single-file Li diffusion channels. However, due to their low concentration (∼ …

Single-file diffusion is a ubiquitous physical process exploited by living and synthetic
systems to exchange molecules with their environment. It is paramount to quantify the …

Using the short-chain-length alkanes from ethane to n-butane as guest molecules, transient
concentration profiles during uptake or release (via interference microscopy) and tracer …

We study the single file diffusion of a cyclic chain of particles that cannot cross each other, in
a thermal bath, with long-ranged interactions and arbitrary dam**. We present simulations …

The topic of this chapter concerns diffusion studies via nuclear magnetic relaxation in solids
with deviations from three-dimensional (3D) long-range order. These include, on the one …

The study of crystals of molecular wheels as nanoporous materials is reported.
Hyperpolarized 129Xe NMR spectroscopy has been used to characterize the mode of …
