The dilution enthalpies of D-mannitol and D-sorbitol in aqueous sodium chloride solution at various concentrations have been determined by isothermal microcalorimetry at 298.15 K. The homogeneous enthalpic interaction coefficients over a quite large range of concentration of aqueous sodium chloride solutions have been calculated according to the excess enthalpy concept. The results show that enthalpic pairwise interaction coefficients (h 2) of D-mannitol and D-sorbitol are positive in aqueous sodium chloride solution and become more positive with increase of the concentration of sodium chloride. The results are interpreted in terms of the different conformations of the two polyols, solute-solute and solute-solvent interactions involved by solvent effects.

Different types of hybrid constructions, consisting of glass and another material, are analyzed or even newly developed focusing on an optimal structural interaction between both materials and in respect to architectural, static-structural and fabrication criteria. The new, high transparent structural element — hybrid steel-glass beam consists of steel flanges, glass web and bonded connection between them. Long glued joint realized by polymer adhesive is the key element of the structure, therefore the key aspect of the development is the detailing of the steelglass interface and choice of the suitable adhesive. Wide range of adhesives with different mechanical and deformational properties was involved to experimental program. Non-linear Finite Element material models were created in accordance with the results of material tests and than calibrated on steel-glass connection tests. Properly working numerical models of the adhesive layer are being involved to the complex FE model of the hybrid beam and verified by the full-scale tests of the beams with 4 m span.

Studies of the thermal behaviour of binary oxide mixtures containing vanadium(V) oxide (V2O5-TiO2, V2,O5- MoO3, V2,O5-ZrO2 and V2O5-ZnO) have shown that the evolution of gaseous oxygen at fairly low temperatures is characteristic of those systems which are eflective catalysts for the oxidation of hydrocarbons. No weight changes were observed with V2, O5-ZnO mixtures under these conditions and, in accordance with this, zinc(II) oxide does not enhance the catalytic activity of vanadium(V) oxide. In V2O5-containing systems, evolution of oxygen occurs during the reduction of V2O5 to V2O4. This process is accelerated in the presence of certain metal oxides and such acceleration may be caused by structural interactions at the interface of the oxides. Among the systems studied, the formation of compounds such as Mo6V9O40 is thought to be of little significance from the catalytic point of view.
