Formation of the Vilsmeier-Haack complex: the performance of different levels of theory
(Springer, 2011)
Because of discrepancies in the available experimental data, an extensive theoretical investigation of the formation of the Vilsmeier-Haack (VH) complex has been carried out. The barriers to complex formation calculated ...
A study on classification of translation surfaces in pseudo-Galilean 3-space
(Amer Scientific Publishers, 2018)
In this paper, we characterize translation surfaces such as translation surfaces of type-I and type-II in pseudo-Galilean 3-space G(3)(1). Then we study some classification of translation surfaces of type-I in pseudo-Galilean ...
The effect of carbonization temperature, carbonization time and impregnation ratio on the properties of activated carbon produced from Arundo donax
(Elsevier Science Bv, 2018)
Activated carbons from Arundo donax were obtained by varying impregnation ratio, carbonization time, and carbonization temperature via chemical activation method. By operating impregnation ratio as 1.5 and carbonization ...
The The validity of Kohlrausch law for the photocurrent transient and the role of N-2/Ar flow ratio in photoconductivity of sputtered CoZnO
(Elsevier Science Sa, 2017)
Co:ZnO (CZnO) ferromagnetic semiconductor layers are coated on the surface of glass and Si substrates by Magnetron Sputter Deposition Method (MSDM) with variable N-2/Ar gas flow ratio. N-2/Ar flow ratio varies from 5 sccm ...
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 ...
