Aram Bagrati (Bagratovich) Nalbandyan (Jan.1, 1908 – Jan.24, 1987) was a Soviet Armenian physicist, prominent in the field of physical chemistry, founder of the Institute of Chemical Physics in Yerevan, Armenia, academician-secretary of the Chemical Department of the Armenian Academy of Sciences (AS). A. B. Nalbandyan is the author of more than 400 scientific articles and five monographs.
Biography
Aram Nalbandyan [1] was born in 1908 in Karaklise (Kirovakan, now Vanadzor). He lost his father at an early age and his grandfather, who was a farrier, was the one who raised him implanting the love for work and appreciation for nature. Aram N. received his general education at the local school. [2]
After school in Karaklise, Aram started his education in the Department of Physics and Mathematics of Pedagogical Faculty of the Yerevan State University. Many highly educated Armenians – graduates from the universities of Moscow, Petersburg and also from the European universities were teaching there at that time. Among them were professors of physics H. Navakatikyan and H. Anjour, prof. of mathematics B. Bagaturyan, prof. of physical chemistry L. Rotinyan [3], academician A. Hakopyan. They all contributed greatly to the development of young Aram Nalbandyan. As a student, Aram worked at the laboratory and participated in the scientific club led by H. Navakatikyan. After graduating from the University in 1930, he worked at the department as an assistant and also delivered lectures on molecular physics.
In 1931 a new Institute of Chemical Physics was created in Leningrad (S.Petersburg). The position of the chief of Institute was assigned to N.N. Semenov,the disciple of the academician A. F. Ioffe. N. N. Semenov, the future Nobel prize winner, had big plans for developing science at his Institute. To carry out these plans he decided to involve young talented graduates from other cities of the USSR. From the Yerevan State University Aram Nalbandyan was chosen to go to Leningrad where he joined the group of highly motivated young scientists. [4]
Nalbandyan’s research was dedicated to the studies of the kinetics and mechanism of branched chain reactions. In the period between 1931 and 1950 he investigated in detail the mechanism of oxidation of hydrogen as an example of a branched chain reaction. The collected experimental data and its careful theoretical processing became a brilliant prove of the main principles of the theory of the branched chain reactions that were formulated by N.N. Semenov. [5] [6]
On basis of his experimental and theoretical research A.B. Nalbandyan obtained his Candidate (1935) and Doctoral (1943) degrees.
During the years of World War II, Institute of Chemical Physics was relocated from Leningrad to the city of Kazan. There, while his wife Bella L. Nalbandyan(Sinaeva) worked as a Medical Chief of the Army Hospital, Nalbandyan studied methods of production of explosives and their characteristics. For his achievements he was awarded with medal for Heroic Labor During The Great Patriotic War (1946).
In 1949 jointly with V.V. Voyevodsky he published the monograph "Mechanism of Hydrogen Oxidation and Combustion" [7]. This monograph was honored with D.I. Mendeleev's Prize in 1952.
From 1957 to 1966 A.Nalbandyan headed the Laboratory of Hydrocarbon Oxidation at ICP, AS USSR (Moscow) and from 1951 to 1959 was the Chair of the Department of Physics at the Moscow Electrotechnical Institute of Communications. Research on degenerated branching in oxidation of organic compounds done by Nalbandyan and his colleagues was an important contribution to the theory of chain reactions.
A series of researches on the mechanism of methane oxidation resulted in a proposal for the industrial production of formaldehyde by direct methane oxidation. In 1962 the authors of this work, headed by Nalbandyan, were awarded a Big Gold Medal of the Exhibition of Economic Achievements of the USSR. In 1959 Nalbandyan published a popular scientific book entitled "Formaldehyde - a Material for Plastics" written jointly with N.S. Enikolopyan [8].
While living in Moscow, A.Nalbandyan was always in close contact with the Armenian scientific community. He always headed the researches of the post-graduate students, trainees and graduates of Yerevan higher schools. In 1959, at the suggestion of the Presidium of the Armenian AS, Nalbandyan founded the Laboratory of Chemical Physics - a new scientific center in Yerevan. In 1960 he was elected a Corresponding member, and in 1963 a full member of the Armenian AS.
In 1967 Nalbandyan with his wife Bella L. moved from Moscow to Yerevan, where he was appointed Director of the Laboratory of Chemical Physics. He was also elected academician-secretary of the Department of Chemistry of the Armenian AS.In 1975 the Laboratory was reorganized as the Institute of Chemical Physics. Until the very end of his life (January 24, 1987) Nalbandyan was the Director and scientific leader of the Institute which now bears his name.
Scientists of the Institute used the kinetic method, developed by A.Nalbandyan and his colleagues, of radical freezing in combination with ESR-spectrometer for detecting polyatomic radicals in gas phase reactions. They were the first to obtain direct experimental data about free radicals in complex, degenerated branched chain reactions which allowed to investigate chemical reactions at a new, higher level and to approach the ways of controlling them for practical purposes. [9]
A.Nalbandyan in his last years paid enormous attention to the processes taking place on the surface of the chemical reactor. Based on the results of studies in this field he concluded that depending on the process conditions, the chain branching could occur on the walls of the reactor as a result of decomposition of unstable intermediate compounds, such as peroxides, with the ejection of radicals into the reactor volume where they will continue the chain propagation in the gas phase. [10]
The results of investigations on the kinetics and mechanism of complex reactions were summarized in Nalbandyan's three monographs written jointly with his disciples: A.A.Mantashyan, I.A.Vardanyan, Y.M.Gershenson.
Contributions were made to the development of new scientific areas: the reactions of free radicals in liquid phase, chemical catalysis, solid phase combustion, etc. In the early seventies Nalbandyan took the initiative to start research on Self-Propagating High Temperature Synthesis of valuable inorganic materials at the Institute. [11] These studies were headed by A.G. Merzhanov, the founder of this scientific direction at the ICP of AS USSR. They are successfully continuing these days.
Nalbandyan was actively involved in the scientific and social activities: Chief Editor of the "Armenian Chemical Journal", member of Editorial Board of the journal "Khimicheskaya Fizika", member of Editorial Committee of Armenian Encyclopedia, member of the Terminology Committee under the Council of Ministers of Armenian SSR. He also paid attention to establishing and developing international relationships - participated in many international conferences and symposiums, often gave lectures outside of the USSR (a course of lectures in Canada, lectures in the Goettingen University (1973) as a Gauss-Professor, lectures in the Catholic University of Leuven, Belgium). In 1979 he joined the New York Academy of Sciences. [12]
A.B. Nalbandyan passed away on January 24th, 1987 in Yerevan.
