ATR-FTIR spectroscopy has been applied to address the effect of confinement on water structure between lipid bilayers. Due to the small light penetration depth, the ATR-FTIR enables study of lipid multibilayer stack within excess water. Our results indicate hydrogen bonding strong dependence on the level of hydration and their weakening in interlamellar water between lipid bilayers in excess water. These results bring new understanding to the confined water and water at molecular interfaces like protein surfaces, carbon nanotubes and porous materials.

Water in wood as a material essentially determines its physical and mechanical properties. Fast and precise moisture content determination is therefore essential to users of wood. Traditional methods for wood moisture content determination are based on the weighing of samples: moisture content is determined from the weight of moist and completely dry sample of wood. That requires samples drying, which is a long and destructive process. We developed a new non destructive, fast and accurate method for MC determination using nuclear magnetic resonance and weight of the moist sample.

A new method for imaging electrical currents (current density sensitivity Enhanced Imaging - EC-CDI) was developed. The method excels by its high speed and significantly greater sensitivity than previously known methods. The ES-CDI method can image currents with a density of at least 20 A / m2, which is almost two orders of magnitude better than previously used methods. The method works well with samples having long T2 relaxation times and is relatively insensitive to diffusion effects on the signal.

By comparison of experimentally derived and modelled aminoacid spin-labelled side-chain rotational motional patterns we have determined the structure of the short-lived state of the C-terminal end of measles virus nucleoprotein and M13 bacteriophage major coat protein. We have joined the site-specific mutagenesis and temperature-dependent EPR-detected motional anisotropies as well as modified modelling of the local rotational spaces based on reduced probabilities of individual rotamers due to coexistence of various side-chains in the same space and within the EPR-spectroscopy time window.

We have studied the effects of switching of the gradient magnetic field on spin dynamics and on measurements of translational dynamics as obtained by the NMR methods. We have also shown a possibility for NMR tomography of samples in the weak Earth’s magnetic field, which is a significant contribution to the common effort of scientists to find a simple method of magnetic resonance imaging. With the editor’s invitation, these results were presented in one of the most prestigious journals in the field of NMR.
