Bonnet Canal Surfaces
(2019)
We know that Bonnet surfaces are the surfaces which can admit at least one non-trivial isometry that preserves the principal curvatures in the Euclidean three-dimensional space. In this study, firstly, we have examined the ...
Tuning of electronic structure, magnetic phase, and transition temperature in two-dimensional Cr-based Janus MXenes
(Amer Physical Soc, 2021)
Two-dimensional (2D) transition metal carbides and nitrides, called as MXenes, displaying astonishing properties are emerged as a new class of 2D layered materials. In this study, we have studied the structural, electronic, ...
Hermite-hadamard type ınequalities for multiplicatively s-convex functions
(2020)
In this paper, some integral inequalities of Hermite-Hadamard type for multiplicatively s-convex functions are obtained. Also, some new inequalities involving multiplicative integrals are established for product and quotient ...
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 ...
Modified Li Chains As Atomic Switches
(2013-09-06)
We present electronic structure and transport calculations for hydrogen and lithium chains, using density functional theory and scattering theory on the Green’s function level, to systematically study impurity effects ...
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 ...
On the generalized C*- valued metric spaces related with Banach fixed point theory
(Inst Advanced Science Extension, 2017)
The Banach contraction principle, which shows that every contractive mapping has a unique fixed point in a complete metric space, has been extended in many directions. One of the branches of this theory is devoted to the ...
