Laboratory history

    In 1960, Academician A.Q.Atakhojayev founded the "Optics" scientific school and established a scientific laboratory of problems in the faculty based on the decision of the Government of the Republic of Uzbekistan. In 1953-1957, a number of talented young students were attracted to the laboratory of problems established by A.Q.Atakho'jayev, who studied "Optical properties of liquids" in cooperation with the scientists of St. Petersburg University Prof. E.F.Gross and Prof. M.F.Vuks, and the formation of the School of Optics was achieved.

    Professors in the laboratory of problems working under the direct leadership of Academician A.Q.Atakho'jayev: F.Kh.Tukhvatullin, Sh.Fayzullayev, L.M.Sobirov, N.Nizomov, A.Jumbaev, R.Akhmedjanov, S.Astonov, F.Ganiyev, U.N.Tashkenbayev, N.B.Eshkobilov , H.Hushvaktov, candidates of science: T.Otarova, B.S.Jorayev, Kh.Torakulov, M.Hamrokulov, U.Jurayev, M.Muminova, Y.Turakulov, U.Zohidov, E.Shermatov, G'.Murodov, O.Yakubov, R.Eshboriyev, S.Qurbaniyazov, A.Shodiyev, E.Khojiyeva, Z.Mamatov, A.Absanov, Q.Xudaynazarov, Sh.Ismailov, M.Kuliyeva, B.Burkhanov, A.Shodiyev, B.Khudoyberdiyev, G'.Sharipov, B.Khudaykulov, and more than 20 doctors of science and more than 40 candidates of science. Currently, they are working effectively in republican and SA network institutes, higher education institutions and production enterprises.              

Laboratory activities

    The "Molecular Spectroscopy" scientific laboratory is equipped with modern equipment (Renishaw inVia Raman spectrometer). Spectroscopic characteristics of nano-sized molecular clusters of biological objects necessary for life are studied in the laboratory under the leadership of Professor A.Jumabaev. With the help of Raman and IR spectroscopy, the quality of biologically active substances that play an important role in the activity of food, medicine and other living organisms are analyzed. Laboratory staff from Kyiv National University, St. Petersburg State University, Seoul National University of South Korea, Kokagiun University of Japan, Odessa National University, Tajikistan National University, Institute of Scintillation Materials of Ukrainian SA, Institute of Organic Chemistry of Ukrainian SA, Institute of Atomic and Molecular Physics of Belarusian SA and Tomsk State University is being conducted scientific work with the staff of our laboratory.

1 doctoral student (DSc): 5 basic doctoral students, 1 target doctoral student and 1 independent researcher worked in the laboratory. 2022 basic doctoral student.

 

Renishaw inVia Raman spectrometer

    With the help of this spectrometer, the spectroscopic characteristics of biological objects necessary for life are studied, and the quality of biologically active substances that play an important role in the activity of food, medicine and other living organisms is analyzed.

    Also, ab-initio calculations are carried out in the laboratory with the help of modern computers in order to supplement and compare the experimental results.
