80th anniversary of
Academician B. Baranowski
Professor Bogdan Baranowski was born
27.10.1927 in Kępno, northern-east from
Wrocław.
His personality was formed by interwar
conditions on territory of former Prussian
conquest, and the difficult war and occupation
times. As from the youth years he was interested
in chemistry, he undertook the chemical studies
at the University and Technical University in
Wrocław (1947-51). His scientific career
developed quickly. Yet before graduation, as
outstandingly talented, became an assistant at the
new created Department of Physical Chemistry,
directed by Prof. K.Gumiński. In 1954 they both
moved to the Jagiellonian University in Kraków,
where he worked at the new created Department
of Theoretical Chemistry. Two years later,
invited by the Institute of Physical Chemistry
Baranowski came to Warsaw to the Department
of Physicochemistry of Electrode Processes,
directed by Prof. M.Śmiałowski. Soon after he
became the candidate of sciences (1956) and in
1964 - at the age of 37 years, received professor
title.
From 1956 his career, characterized by
numerous stays abroad, has been strictly
connected with the Institute of Physical
Chemistry. Since 1960 he directed a department
and 5 years later became Head of his own
scientific group – the Department of Physical
Chemistry of Solids.
The scientific papers of Professor
Baranowski characterize a large variety. At the
beginning they concerned mainly on thermo- and
electrothermodiffusion in liquid solutions.
Baranowski elaborated a thermodiffusion
method for separation of electrolytes, and as the
first applied the irreversible thermodynamics and
statistical mechanics to surface systems. The next achievement was the phenomenological
theory of thermodiffusion in liquid metallic
alloys. In electrolyte solutions he extended
Deby’s salt effects theory and discovered the
influence of chemical reactions on
thermodiffusion. Among his first papers one
finds also the semi-empirical theory of
antyraoultic properties of liquid solutions.
Professor Baranowski was greatly
interested in irreversible thermodynamics. Until
half of 60’s, arrised his most important
theoretical papers on this discipline. One of the
achievements was the extent of theory of
dissipative structures, (definied by I.Prigogine),
and the proposition of their classification. He
explained, that the development of biological
organisms are in agreement with the II law of
thermodynamics.
Besides the adoptions mentioned above, he
extended a contribution to the description of
thermodiffusion in multiatomic gases; described
transfer processes in multicomponent two-phase
systems and in liquids under non-hydrostatic
pressures, gave the phenomenological theory of
electrotransport in solid metallic alloys. Later,
the irreversible thermodynamics was adopted by
him for membrane processes and for the
description of diffusion in metals under pressure.
As the fruit of numerous papers arised
the monograph entitled: “Non-equilibrium
Thermodynamics in Physical Chemistry” (1974,
was published in Polish and German).
The crucial event in scientific work of
Professor Baranowski was the discovery of the
hydride phase in electrochemically saturated
nickel (1958), what led to the construction of the
first hydrogen high pressure vessel. This opened
a new trend, causing, that his research from this
time was connected mainly with metal hydrides
under high pressures. There were investigations
of thermodynamic properties of metal-hydrogen
systems, the electrical and magnetic properties
under hydrogen pressures, the absorption and
desorption kinetics, and the penetration depths of
hydride phases. Baranowski was the first, who
synthesized by high pressure method hydrides of
nickel (1966), chromium (1972), manganese
(1975) and aluminium (1983) and gave their
thermodynamic characteristic. After the hydrides
syntheses followed deuterides of nickel, and
chromium. He also examinated the properties of
systems, such as: Ni-Mn-H, Ni-Co-H(D),
Ni-Cu-H, Ni-Fe-H, Ni-Cr-H, Pd-Rh-H, Pd-Pt-H,
Pd-Ag-H and Pd-Ni-H. Using high pressure
apparatus he obtained the stoichiometric
palladium hydride and contributed to the
discovery of its superconductivity. Besides transition metals, the subject of his
investigations were also light and rare earth
metals, solid organic compounds and at least –
the phase transitions in crystals of acidic salts.
Among the multitude (340) of his papers,
one finds also those on metallic hydrogen, the
electrochemical analogon of the Benard
problem, and strictly polemic papers. All of
these present his extended scientific interests and
large assiduity.
