Investigations of metal–organic frameworks are presented. This substance class is of interest for applications in gas storage (hydrogen, methane), separation, catalysis, and sensor technology. The properties of the material depend on the mobility of alkyl or alkyloxy side chains. We have determined that the side-chain methylene groups move highly anisotropically with a relatively short correlation time. Furthermore, we could improve the analysis procedure for the experiment used here.

R-proton-detected local-field NMR is a powerful method to obtain structural information from biological membrane models. However, the conventional analysis of experiments, by using a Fourier transform in the indirect time-domain and reading-off splittings, is unsuitable to investigate complex systems. One then needs to model the experimental data. Fitting the experimental data with simulations that account for radiofrequency field inhomogeneity enables accurate modeling of R-PDLF data.

A large amount of organic carbon (OC) in soil is protected against decay by bonding to minerals. We studied the release of mineral-bonded OC by NaF–NaOH extraction and H₂O₂ oxidation. Unexpectedly, extraction and oxidation removed mineral-bonded OC at roughly constant portions and of similar age distributions, irrespective of mineral composition, land use, and soil depth. The results suggest uniform modes of interactions between OC and minerals across soils in quasi-steady state with inputs.

This work presents systematic methodological study of one of the types of the nuclear magnetic resonance experiments that enables study of molecular dynamics on a millisecond timescale. A modification of a standard experiment was suggested that excludes possible artefacts and distortions. It has been demonstrated that the standard experiment reveals slow overall motion of proteins in a rigid crystal lattice, whereas the artefact-free experimental setup demonstrates that the proteins are rigid.
