    Volumetric properties of mixtures of water and methanol H/D-isotopomers between 5 and 45°C (1996)
    Springer
    Journal of solution chemistry 25 (1996), S. 191-201 
    Details
    ISSN: 1572-8927
    Keywords: Solvent isotope effects ; methanols ; H/D-isotopomers ; aqueous solutions ; volumetric properties
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract Densities of H/D-isotopomers mixtures of water (H2O, D2O) and methanol (CH3OH, CD3OH, CH3OD, and CD3OD) over the full range of compositions were measured at 5, 15, 25, 35, and 45°C. Results have been used to calculate molar volumes, excess molar volumes, apparent molar volumes, and isotope effects of the mixtures. The volumetric properties are discussed in terms of the structural changes in water-methanol solutions under the influence of isotope substitution.

    Carbon states and kinetics of carbon deposition from ethylene at Pt(110) surface (1998)
    Springer
    Reaction kinetics and catalysis letters 65 (1998), S. 381-388 
    Details
    ISSN: 1588-2837
    Keywords: Carbon ; kinetics ; surface state ; XPS ; photoelectron spectroscopy

    Topics: Chemistry and Pharmacology
    Notes: Abstract The nature of high temperature carbon states at Pt(110) has been studied by X-Ray Photoelectron Spectroscopy. The formation of diamond-like carbon (DLC) is reported for the first time. The kinetics and temperature-programmed reactions of DLC were numerically simulated.

    Kinetics of carbon deposition from ethylene on Pt(110) surface (1997)
    Springer
    Reaction kinetics and catalysis letters 62 (1997), S. 299-304 
    Details
    ISSN: 1588-2837
    Keywords: carbon ; kinetics ; surface state
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract The formation of carbonaceous deposits on Pt(110) surface due to ethylene decomposition in the temperature range of 770–970 K has been studied. Both kinetic and XPS data show that chemisorbed carbon (with no C−C bonds, but only C−Pt bonds) forms at T=770–870 K, the saturation coverage θs being about 1 ML. At higher temperatures, θs increases by a factor of 1.5, indicating the formation of more densely packed carbon species (DPC) due to C−C bonding. A kinetic model has been proposed to describe the process of carbon conversion.

    Control of the selectivity in partial oxidation of hydrocarbons (1999)
    Springer
    Reaction kinetics and catalysis letters 66 (1999), S. 47-54 
    Details
    ISSN: 1588-2837
    Keywords: Partial oxidation ; hydrocarbons ; catalyst circulation
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract A simple kinetic model for the partial oxidation of hydrocarbons on two types of sites was used to study the factors influencing the selectivity to the desired product. It is possible to increase the selectivity significantly by regulating the ratio of the surface concentrations of partial and deep oxidation sites by a periodic temperature treatment.

    Multiplicity of regimes in a dual-reactor system for partial oxidation of hydrocarbons with the catalyst unsteady state (1999)
    Springer
    Reaction kinetics and catalysis letters 67 (1999), S. 213-218 
    Details
    ISSN: 1588-2837
    Keywords: Partial oxidation ; hydrocarbons ; catalyst circulation ; multiplicity
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract A mathematical modeling of a dual-reactor system based on a simple kinetic scheme with two types of sites (accounting for deep and partial oxidation) has been performed. It has been shown that it is possible to regulate the state of a catalyst in the reaction zone by varying the rate of the catalyst circulation between the reactors, thus, significantly increasing the reaction selectivity. A region of multiplicity of the process stationary regimes has been found. This region appeared to become smaller with the increase of the catalyst circulation rate.
