Wide-line 1 H NMR measurements were extended and all results were interpreted in a thermodynamics-based new approach on aqueous solutions of thymosin-β4 (Tβ4 ), stabilin cytoplasmic domain (CTD), and their 1 : 1 complex. Energy distributions of potential barriers controlling the motion of protein-bound water molecules were determined. Heterogeneous and homogeneous regions were found in the protein-water interface. The measure of heterogeneity of this interface gives quantitative value for the portion of disordered parts in the protein. Ordered structural elements were found extending up to ∼20 % of the individual whole proteins. About 40 % of the binding sites of free Tβ4 get involved in bonds holding the complex together. The complex has the most heterogeneous solvent accessible surface (SAS) in terms of protein-water interactions. The complex is more disordered than Tβ4 or stabilin CTD. The greater SAS area of the complex is interpreted as a clear sign of its open structure.

Wide-line (1) H NMR measurements were extended and all results were reinterpreted in a new thermodynamics-based approach to study aqueous solutions of thymosin-beta4 (Tbeta4 ), stabilin C-terminal domain (CTD) and their 1:1 complex. The energy distributions of the potential barriers, which control motion of protein-bound water molecules, were determined. Heterogeneous and homogeneous regions were found at the protein-water interface. The measure of heterogeneity gives a quantitative value for the portion of disordered parts in the protein.

We have investigated the rotor-stator molecular crystal fullerene-cubane (C 60 .C 8 H 8 ) by 1 H'NMR spectroscopy in the temperature range of 130 to 380 K. The 1 H line is broad and exhibits fine structure characteristic of a multispin spectrum, indicating the absence of angular reorientations of the cubane molecule. The temperature and field dependence of the spin-lattice relaxation rate of cubane protons is well explained in terms of field fluctuations arising from reorientations of the C 60 molecules. Despite the closely packed structure, the activation energy of these reorientations, 650 K, is close to that observed in the high-temperature phase of pure C 60 indicating that the static cubane molecules act as efficient bearing for the rotating fullerene molecules.

Results of electrical resistance measurements are given on Pd80 Ag20 alloy during hydrogen uptake from gaseous H2 atmosphere and from liquid electrolyte by cathodic charging. For both cases in the course of a monotonous increase of the hydrogen concentration in the alloy, the electrical resistivity shows anomalous behavior. These kinetic curves reflect the effect of phase changes in the non-equilibrium state. The ‘non-equilibrium’ expression is used in this entire work in the sense that no care was taken in waiting for the stable value of resistivity after any partial filling, but the resistivity was frequently measured while the sample was continuously charged with hydrogen. A model has been proposed for the interpretation of the experimental findings.

The field-independent 31P NMR linewidth, δHo, is measured in nonmagnetic amorphous Ni-based alloys. In addition, the second moment contribution M originating from direct nuclear dipole–dipole interaction is calculated using Van Vleck's theory based on a computer generated DRPHS amorphous model cluster. The calculated second moment M and the experimental second moment M obtained from δHo by Gaussian line shape approximation (i.e., M = (δHo)2/4) agree fairly well for a (Ni0.27Cu0.73)82P18 metallic glass. In the case of amorphous NiP and NiPB alloys M exceeds M by a factor of two or three. This excess second moment seems to indicate the presence of some indirect indirect interactions between nuclear spins. [Russian Text Ignored].
