    • Amorphous to tetragonal zirconia anostructures and evolution of valence and core regions 

      Vempati S.; Kayaci-Senirmak, F.; Ozgit-Akgun, C.; Bıyıklı, Necmi; Uyar, Tamer (American Chemical Society, 2015)
      In this report, we study the evolution of valence band (VB) structure during a controlled amorphous to tetragonal transformation of ZrO2 core-shell nanostructures fabricated from electrospun nanofiber template (at 130, ...
    • Hydrogen-induced sp2-sp3 rehybridization in epitaxial silicene 

      Solonenko, D.; Dzhagan, V.; Cahangirov, S.; Bacaksiz, C.; Sahin, H.; Zahn, D. R. T.; Vogt, P. (American Physical Society, 2017)
      We report on the hydrogenation of (3×3)/(4×4) silicene epitaxially grown on Ag(111) studied by in situ Raman spectroscopy and state-of-the-art ab initio calculations. Our results demonstrate that hydrogenation of (3×3)/(4×4) ...
    • X-ray photoelectron spectroscopic and in-situ infrared investigation of a Ru/SiO2 catalyst 

      Sayan, Şafak (Bilkent University, 1997)
      A 4 wt% Ru/Si02 catalyst which was previously prepared via an incipient wetness technique using a ruthenium nitrosyl-nitrate [Ru(N0)(N03)3] solution and a commercially available precursor (ruthenium nitrosyl-nitrate) were ...
