Catalase with the commercial catalase name Terminox Ultra is widely used in the textile industry in bleaching processes. This enzyme is used to catalyse the decomposition of residual hydrogen peroxide into oxygen and water. In this study catalase was kept for about 30 hours in water baths in a temperature range from 35 to 70°C. For the first time, the kinetics of thermal deactivation of this enzyme was examined using an oxygen electrode. Stability of the enzyme depends strongly on temperature and its half-life times are 0.0014 h and 7.6 h, at 35 and 70°C, respectively.

The structural and magnetic properties of three magnetron sputtered multilayers at the 2nd maximum of antiferromagnetic coupling were studied using ^{59}Co NMR spectroscopy: [Co(20 Å)/Cu(20 Å)]_{20}, [Co(20 Å )/ Ru(18 Å)]_{20} and a heterostructure, in which non-magnetic spacers alternated between Cu and Ru. Co/Cu interfaces were found to be relatively sharp, extended over 3 monolayers, while the Co/Ru interfaces extend over 6 monolayers due to the good miscibility of Co and Ru. The NMR restoring field in the heterostructure is found to be the average of the restoring fields in both reference samples.

The M_1/MgO/M_2 trilayer tunnel magnetoresistance systems are studied by means of X-ray diffraction, NMR, and transmission electron microscopy techniques. As M_1 and M_2 electrodes we used Co, Fe, and CoFe layers. The growth mechanism and structural quality of both electrodes and of the epitaxial MgO barrier forming the magnetic tunnel junctions are experimentally examined. It is shown that the crystallographic coherence of magnetic tunnel junctions across the MgO barrier is significantly disturbed by imperfect crystal structure of magnetic electrodes. The NMR results indicate a difference in short-range order between bottom and top electrodes.
