  • Computational scheme for breakup of 11Be on light targets 
    Valiolda, D.S.; Janseitov, D.M.; Melezhik, V.S. (2023)
    We investigate the Coulomb breakup of the 11 Be halo nuclei on a light (carbon) target within nonperturbative time-dependent approach including the low-lying resonance 5/2+ of 11 Be (E= 1.232 MeV). We had found considerable ...
  • Electron-hole trapping centers in alkali metal sulfates with Dy3+ impurities 
    Nurakhmetov, T.N.; Alibay, T.T.; Bakhtizin, R.Z.; Pazylbek, S.; Kainarbay, A.Zh.; Zhunusbekov, A.M.; Sadykova, B.M.; Tolekov, D.A.; Shamieva, R.K.; Nurpeissov, A.S. (2023)
    The Na2SO4 − Dy samples were obtained by slow evaporation method. The spectroscopic methods were used to study the mechanisms of formation of electron and hole trapping centers. Intrinsic recombination emission of 2.9–3.1 ...

  • Influence of surfactants on the formation and growth of cadmium telluride nanoplatelets 
    Akhmetova, A.S.; Ospanova, A.K.; Yussupbekova, B.N.; Alibay, T.T. (2023)
    The article presents a comprehensive review of the current research on the use of surfactants in CdTe nanoplatelet synthesis, including a discussion of the various types of surfactants that have been used and their effects ...
  • Luminescent properties of BaxMg(2−x) F4 :W ceramics 
    Koketai, T.A.; Strelkova, A.V.; Zhunusbekov, A.M.; Karipbayev, Zh.T.; Lisitsyna, L.A.; Chakin, A.M. (2023)
    Ceramics based on alkaline earth metal fluorides activated by tungsten has been obtained by radiation synthesis. The synthesis was realized by direct action on the mixture with an activator of a powerful flow of high-energy ...
  • Non-destructive structural studies of ceramic fragments of ancient tribes of Kazakhstan 
    Zhomartova, A.Zh.; Bakirov, B.A.; Kichanov, S.E.; Zhumatayev, R.S.; Toleubayev, A.T.; Shakenov, S.; Kozlenko, D.P. (2023)
    The phase composition of several fragments of the ancient ceramic of the early medieval settlement of Asusay and burial ground Eleke Sazy in the modern Republic of Kazakhstan has been studied using neutron diffraction ...
  • Super–protonic conductors for solid acid fuel cells (SAFCs): a review 
    Afroze, Sh.; Reza, Md S.; Somalu, M.R.; Azad, A.K. (2022)
    Fuel cell holds the promise of being environmentally friendly and becomes one of the alternatives for renewable energy. Solid acids have super–protonic behavior which allows them to become conductors. It can function at ...
