    • Amino acid 2-aminopropanoic CH 3CH(NH 2)COOH crystals: Materials for photo- and acoustoinduced optoelectronic applications 

      Ali Hussain, Reshak, Prof. Dr.; Lakshminarayana, Gandham; Kamarudin, Hussin, Brig. Jen. Dato' Prof. Dr.; Kityk, Iwan V.; Auluck, Sushil, Dr.; Berdowski, Janusz M.; Tylczynski, Zbigniew (Springer Science+Business Media, LLC, 2012-10)
      Photo-induced treatment of L-alanine single crystals grown by slow evaporation method at an ambient temperature was performed using a 25 ps Nd:YAG pulsed laser in the presence of an external acoustic filed. The changes of ...

    • Band structure, density of states, and crystal chemistry of ZrGa₂ and ZrGa₃ single crystals 

      Ali Hussain, Reshak, Prof. Dr.; Lakshminarayana, Gandham; Ebothe, Jean; Fedorchuk, Anatolii O.; Fedyna, M.F.; Kamarudin, Hussin, Brig. Jen. Dato' Prof. Dr.; Mandracci, P.; Auluck, Sushil, Dr. (Elsevier, 2013-04)
      Using FP-LAPW Method we have performed calculations of the band structure of the ZrGa₂ and ZrGa₃ crystals. The all-electron full potential linearized augmented plane wave method was used to solve the Kohn Sham DFT equations. ...

    • Electronic spectral parameters and IR nonlinear optical features of novel Ag 0.5Pb 1.75GeS 4 crystal 

      Kogut, Yu; Khyzhun, Oleg Yu; Parasyuk, Oleg V.; Ali Hussain, Reshak, Prof. Dr.; Lakshminarayana, Gandham; Kityk, Iwan V.; Piasecki, Michał M. (Elsevier B.V., 2012-09)
      In this paper, we report on novel Ag0.5Pb1.75GeS4 single crystals grown by the Bridgman–Stockbarger method. For these crystals we have performed X-ray photoelectron spectroscopy (XPS) studies of the valence-band and ...

    • Er–Pr doped tellurite glass nanocomposites for white light emitting diodes 

      Kityk, Ivan V; Nasser Saleh, Alzayed; Ahmed M., El-Naggar; Reben, Manuela; Wasylak, Jan; Lakshminarayana, Gandham; Ali Hussain, Reshak, Prof. Dr. (Elsevier B.V., 2012-03)
      In this paper, optical glass nanocomposites (nanoparticles sizes up to 100 nm) with composition TeO2–WO3– PbO–xEr2O3–yPr6O11 (x= 0.30 mol%, y= 0.70 mol%) embedded into polymer matrices was reported. The two types of ...

    • Influence of different exchange correlation potentials on band structure and optical constant calculations of ZrGa2 and ZrGe2 single crystals 

      Ali Hussain, Reshak, Prof.Dr.; Fedorchuk, Anatolii O.; Lakshminarayana, Gandham; Alahmed, Zeyad A.; Kamarudin, Hussin, Brig. Jen. Dato' Prof. Dr.; Auluck, Sushil (Elsevier B.V., 2013-10)
      The all-electron full potential linearized augmented plane wave method was used to solve the Kohn Sham DFT equations. We have employed different approximations for the exchange correlation potentials, namely: LDA, GGA and ...

    • Laser operated elasto-optical features of La 2CaB 10O 19:Pr 3+ polymer nanocomposites 

      Majchrowski, Andrzej A; Lakshminarayana, Gandham; Ali Hussain, Reshak, Prof. Dr.; Michalski, Edward A.; Olifierczuk, Marek; Oźga, Katarzyna; Jaroszewicz, Leszek R.; Lukasiewicz, Tadeusz; Szota, Michał; Nabialek, Marcin (Elsevier B.V., 2012-10)
      We have discovered a principal role of the polymer matrices on the spectral dependences of piezooptical coefficients of La 2CaB 10O 19:Pr 3+ (LCBO:Pr) nanocomposites formed by polymethylmethacrylate (PMMA) and polycarbonate ...
