In 1970, he entered to the post graduate courses in I.S.Kurnakov Institute of General and Inorganic Chemistry under USSR AS and in 1973 he defended a PhD thesis.
The following degrees and titles were awarded: Senior staff scientist on specialty inorganic chemistry 1975, doctor of chemical sciences 1985, professor 1988, corresponding member of the AS 1987, academician of the AS RT 1993.
Academician Mirsaidov Ulmas Mirsaidovich is the author of 450 scientific articles, 15 monographs, 75 inventor's certificates and patents.
For the first time in Tajikistan, he started systematic investigations in the field of lightweight metals hydrides and power-consuming substances chemistry.
In his works Prezidenti AN Tajikistana, Sarvaroni fidokori ilm, Oni sostavlyayut slavu tajikskoi nauki and Ustodoni man, the well-known scientists' lives and activity of the country are described.
A number of works carried out in 1970 – 1990 years were relevant to aluminum chemistry – potential solid propellant components and hydrogen sources.
Academician U.M.Mirsaidov's synthesized compounds are used as hydrogen sources, catalyst and selective reducing agents as well as effective materials for enginery.
Reliability of derived results is confirmed by detailed investigation of physical and chemical properties of dedicated compounds.
Original and effective methods of different hydride complexes synthesis are proposed on the basis of systematic investigation of binary hydrides interaction and metals alumohydrides with electron-seeking reagent of different acceptor force (chlorinated reagents, aryl (alkyl) halogenides, boro-, and lithium alumohydride, etc.)
After USSR disintegration Prof. U.M.Mirsaidov focused the whole scientific potential of Chemistry Institute on solution of industry and agricultural problems of sovereign Tajikistan.
The staff of department headed by U.M.Mirsaidov developed one stage synthesis method of “catalyst” for new techniques needs with expected economic effect 6 million rubles (data from 1990).
Generally speaking, science is integral part of culture and it must serve for enrichment of society’s spiritual life, moral health of a nation.
Up to now more than 40 doctoral and more than 300 PhD (kandidat nauk) dissertations in the field of inorganic, organic and physical chemistry are defended in the Council in the area of chemical and technical sciences.
Currently, owing to U.M.Mirsaidov the most required directions as complex reprocessing of mineral raw materials and residues as well as radioecology are developing.
In his works “Prezidenti AN Tajikistana”, “Sarvaroni fidokori ilm”, “Oni sostavlyayut slavu tajikskoi nauki” i “Ustodoni man”, the well-known scientists’ life and activity of our country are described.
Over a period of his activity as president of the AS RT, academician U.M.Mirsaidov strongly practiced principle of faithful service to the people, the foundation of which is laid by organizers.
In front of scientists of Academy he set the problem of mobilization of statehood development, socio-economic and spiritual advance of the country.
U.M.Mirsaidov's constant efforts on effectiveness increase of Technical Cooperation Programs allowed implementation of the projects in the field of nuclear medicine, Republican oncology center modernization, soil erosion identification by the help of radionuclides, carrying out monitoring of Tajikistan’s uranium tailing dumps and re-equipment in SE “Vostokrdemet” laboratory and others.
The high priority of NRSA AS RT allows carrying out large scale international conferences and seminars annually in Dushanbe under the auspices of the IAEA.
