Synthesis, characterization and comparative studies on the photophysical and photochemical properties of metal-free and zinc(II) phthalocyanines with phenyloxyacetic acid functionalities
(Pergamon-Elsevier Science Ltd, 2011)
The synthesis and characterization of new peripherally and non-peripherally tetra-substituted metal-free and zinc(II) phthalocyanines with 2-, 3- and 4-phenyloxyacetic acid functionalities are described for the first time ...
Metal (Al, Fe, Mn and Cu) distributions and origins of polycyclic aromatic hydrocarbons (PAHs) in the surface sediments of the Marmara Sea and the coast of Istanbul, Turkey
(Pergamon-Elsevier Science Ltd, 2011)
In this study, total metal (Al, Fe, Mn and Cu) and PAHs analyses have been done in the surface sediments. Sediment samples have been collected from seven parts of the Marmara Sea and the coast of Istanbul during 2009. Total ...
Characterizations of special time-like curves in Lorentzian plane L-2
(World Scientific Publ Co Pte Ltd, 2017)
In this paper, we first obtain the differential equation characterizing position vector of time-like curve in Lorentzian plane L-2. Then we study the special curves such as Smarandache curves, circular indicatrices, and ...
Special functions in transferring of energy; a specific case: Airy function
(Sila Science, 2012)
Analysis of transferring of transient signals along time-harmonic waveguide modes consists of two main parts. The first one is a modal basis problem. The second one is a modal amplitude problem. Surplus of energy could be ...

AFM induced diffusion of large scale mobile HOPG defects
(Springer Heidelberg, 2019)
Defects on crystal and/or thin film surfaces play an important role in their physical and chemical properties. Diffusion or motion of such structures results in microstructural dynamic changes. The diffusion of single ...
Synthesis, characterization, spectroscopic and electrochemical properties of phthalocyanines substituted with four 3-ferrocenyl-7-oxycoumarin moieties
(Elsevier Science Sa, 2011)
The synthesis, spectroscopic and electrochemical properties of the tetra-(3-ferrocenyl-7-oxycoumarin)substituted zinc (II) and cobalt (II) phthalocyanines (3 and 4) are reported for the first time. The synthesis of novel ...
Descriptive statistics and risk assessment for the control of seasonal pollutant effects of Po-210 and Pb-210 in coastal waters (Canakkale, Turkey)
(Springer, 2018)
Po-210 is absorbed into the human body by seafood intake. Especially, mollusks and mussels are known to have much higher Po-210 concentration than fish among various other types of seafood and are consumed in large quantities ...
Synthesis of Au-doped magnetic nanocomposites: structural, magnetic, and catalytic properties
(Springer, 2021)
In this work, Fe3O4 magnetic nanoparticles (MNPs) were produced using the co-precipitation method. The surface of the produced MNPs was covered with TEOS and APTES as a shell and the APTES shell is doped with Au nanoparticles ...
