On Yurij Kalyuzhnyj’s 50th birthday
Yurij Kalyuzhnyj was born on July 20, 1951 in Lviv. Having graduated from
the Physics Department of the Lviv University in 1973 he began his work as an
engineer at the Institute for Geology and Geochemistry of Fuse Fuels. In 1980 he
started the postgraduate course in the Lviv Division of Statistical Physics of the
Institute for Theoretical Physics under the supervision of Prof. I.R.Yukhnovskii and
Prof. M.F.Holovko. His research work was devoted to the development of the site-
site approach in the theory of ion-molecular systems. The results of his studies were
summarized in his candidate thesis which was successfully defended in 1987.
Later on using the diagram analysis he developed the general scheme for con-
structing the multidensity integral equation description of associating fluids with
the center-center type of interaction. This method was successfully applied to the
789
electrolyte and polyelectrolyte solutions. He showed that the multidensity formal-
ism for ionic fluids essentially extends the integral equation theory into the region of
parameters where more traditional theories do not have a convergent solution. The
results for the liquid-gas phase diagram of the fluid of charged hard spheres, which
are in reasonably good agreement with the existing computer simulation predictions
were a great success of this approach.
The consideration of the multidensity integral equation formalism in the limit of
complete association enables Yu.Kalyuzhnyj to formulate the atom-atom approach
in the theory of molecular fluids. He used this theory to investigate equilibrium
properties (distribution functions, equation of state, phase behaviour) of fluids and
solutions of charged oligomers. The results of this research were summarized in his
doctoral thesis “Equilibrium statistical theory of complex and associating liquids in
the atom-atom approach” which Yu.Kalyuzhnyj successfully defended in 2000.
Lately Yu.Kalyuzhnyj has been considering new and important problems in the
liquid state theory. Among them there are solvation thermodynamics of the gas
solubility at subcritical and near-critical conditions, the structure of the fluids under
shear, the modelling of the anomalies of liquid water properties.
Yu.Kalyuzhnyj is a leading researcher of the Institute for Condensed Matter
Physics of the National Academy of Sciences of Ukraine. As a research associate he
has been working at the universities all over the world, including Charles University
(Prague), State University of New York at Stony Brook, University of Tenessee
at Knoxville, etc. He is the author of nearly 100 papers published in international
journals. Among them there is a chapter in the collective monograph in IUPAC
volume on Equations of state for fluids and fluid mixtures (Elsevier 2000).
Yu.Kalyuzhnyj is full of energy and creative plans. The Editorial Board of “Con-
densed Matter Physics” wish him to stay in a good health, happiness and to be
successful in his scientific activity.
