(Springer, 2023)A facile preparation and structural, optical and electrical characterization of undoped and Y-doped CdS thin films are demonstrated through spray pyrolysis changing doping concentration of yttrium atoms in CdS structure. ... -
A facile ultrasonic synthesis approach to 3-H-quinazolinethione derivatives and their urease inhibition studies
(Taylor & Francis Ltd., 2024)In this study, a new series of 3H-quinazoline-4-thione derivatives were synthesized under ultrasonic irradiation conditions with high yield in a short time. The new compounds were characterized by FT-IR,H-1, and C-13 NMR ... -
Family of surface with a common null geodesic
(2009)We analyzed the problem of finding a surfaces family through a null curve with Cartan frame. We constructed a differential equation system such that a given null curve is an isogeodesic curve on a surface. In addition, ... -
Ferrocenyl-substituted dinuclear Cu(II) complex: Synthesis, spectroscopy, electrochemistry, DFT calculations and catecholase activity
(Elsevier Science Bv, 2016)A new ferrocenyl-substituted heterocyclic hydrazide ligand and its Cu(II) complex were prepared. the DFT calculations were performed to determine the electronic and molecular structures of the title compounds. the electronic ... -
Fifty years of adventure: Relations between Turkey and Iceland
(Pamukkale Üniversitesi, 2021)This study deals with Turkey-Iceland relations between 1930 and 1980. Relations between these two countries, which have completely different cultures and geographies, have always been limited because they have a long-distance ... -
The fine spectral tuning of plasmon mode and quantum emitter coupling and its comparison with the dark-hot resonances
(Scientific Technical Research Council Turkey - TUBİTAK, 2022)Localization of incident fields into very small volumes (hot-spots) allows strong light-matter interactions at the hot spots. This makes path interference effects, Fano resonances, visible. Fano resonances can appear due ... -
