Apparent longitudinal relaxation of mobile spins in thin, periodically excited slices

Publikováno v: Diffusion fundamentals. 3(38):1-12

In this contribution, we present simulations and first experimental results on the apparent longitudinal relaxation behavior of mobile spins in thin periodically excited slices. This phenomenon is especially of interest in the context of NMR microima

Long-term observation of adsorbed heavy metal ions in sediment samples by MRI

Autor: Nestle, Nikolaus, Ebert, Martin, Wunderlich, Arthur, Baumann, Thomas

Publikováno v: Diffusion fundamentals. 5(7):1-19

Recently, we have reported studies of transport and sorption of heavy metal ions in water-saturated quartz sand columns under relatively fast water flow. In these experiments, clear indications for a fast and strong adsorption of the ions to the sedi

DAMARIS – a flexible and open software platform for NMR spectrometer control: DAMARIS – a flexible and open software platform for NMRspectrometer control

Autor: Gädke, Achim, Rosenstihl, Markus, Schmitt, Christopher, Stork, Holger, Nestle, Nikolaus

Publikováno v: Diffusion fundamentals. 5(6):1-9

Home-built NMR spectrometers with self-written control software have a long tradition in porous media research. Advantages of such spectrometers are not just lower costs but also more flexibility in developing new experiments (while commercial NMR sy

Water self-diffusion studies in complex materials with fast-relaxing components: static and pulsed field methods revisited

Autor: Gädke, Achim, Friedemann, Karen, Galvosas, Petrik, Stallmach, Frank, Kärger, Jörg, Nestle, Nikolaus

Publikováno v: Diffusion fundamentals. 5(5):1-16

Field gradient NMR techniques have proved very useful for measurements of molecular self-diffusion coefficients in many materials ranging from simple liquids to more complex materials such as polymer melts, porous media and biological tissues. In suc

Diffusion: macroscale dwarf and nanoscale giant

Autor: Nestle, Nikolaus

Publikováno v: Diffusion fundamentals. 6(1):1-24

Diffusion processes of particles or energy exhibit a characteristic scaling behavior with space and time. In this contribution, the background of this scaling behavior will be shortly described and its consequences in physics, chemistry, biology and
