Effect of NiFe layer thickness on properties of NiFe/Cu superlattices electrodeposited on titanium substrate
(Springer, 2019)NiFe/Cu superlattices having different ferromagnetic NiFe layer thicknesses were grown on polycrystalline titanium substrate from a solution containing nickel, iron and copper ions under potentiostatic control. The NiFe ... -
Exploring prospective chemistry teachers' perceptions of precipitation, conception of precipitation reactions and visualization of the sub-microscopic level of precipitation reactions
(Royal Soc Chemistry, 2019)In this study, how prospective chemistry teachers (PCTs) perceive precipitation and conceptualize precipitation reactions at the symbolic level was explored. Further, it was of interest to identify PCTs' visualization of ... -
A note on f-biharmonic legendre curves in s-space forms
(Int Electronic Journal Geometry, 2019)In this paper, we study f-biharmonic Legendre curves in S-space forms. Our aim is to find curvature conditions for these curves and determine their types, i.e., a geodesic, a circle, a helix or a Frenet curve of osculating ... -
On slant magnetic curves in s-manifolds
(Taylor & Francis Ltd, 2019)We consider slant normal magnetic curves in (2n + 1)-dimensional S-manifolds. We prove that gamma is a slant normal magnetic curve in an S-manifold (M2m+s, phi, xi(alpha), eta(alpha), g) if and only if it belongs to a list ... -
Association of human serum paraoxonase-1 with some respiratory drugs
(Wiley, 2019)In this study, we investigated the effects of certain respiratory drugs, which are mainly used on human serum paraoxonase-1 (hPON1; EC 3.1.8.1). hPON1 was purified from human serum, with 354.91 fold and 45% yield by using ... -
Chemical sensor properties and mathematical modeling of graphene oxide langmuir-blodgett thin films
(Ieee-Inst Electrical Electronics Engineers INC, 2019)Graphene oxide (GO) Langmuir-Blodgett (LB) thin films were prepared to use as chemical sensor element. The properties of GO LB thin film layers were characterized via Quartz crystal microbalance (QCM) method. Selectivity ... -
Comparative anatomy on the vegetative organs of genus Ziziphora L. (lamiaceae) from Turkey
(Wiley, 2019)The genus Ziziphora L. (Lamiaceae) is represented by five species (nine taxa) in the Turkish Flora. These taxa are Z. clinopodioides Lam. (subsp. elbursensis, subsp. filicaulis, subsp. kurdica, subsp. rigida), Z. capitata ... -
Langmuir-blodgett film properties of based on calix[4]resorcinarene and the detection of those against volatile organic compounds
(Springer Heidelberg, 2019)To determine their inherent properties, thin films of calix[4]resorcinarene (C11AMINE) were deposited using the Langmuir-Blodgett (LB) technique onto a suitable substrate. Prior to the LB thin film preparation, this molecule ... -
Easy controlled properties of quaternary fenicrcd thin films deposited from a single dc magnetron sputtering under the influence of deposition rate
(Springer, 2019)The quaternary FeNiCrCd thin films were produced from a single FeNiCrCr source on a commercial flexible polymer substrate using one dc magnetron sputtering technique. For that, a series of the films with a thickness of 50 ... -
Iterating the sum of mobius divisor function and Euler Totient Function
(Mdpi, 2019)In this paper, according to some numerical computational evidence, we investigate and prove certain identities and properties on the absolute Mobius divisor functions and Euler totient function when they are iterated. ... -
Discontinuity at fixed points with applications
(Belgian Mathematical Soc Triomphe, 2019)In this paper, we study new contractive conditions which are strong enough to generate fixed points but which do not force the map to be continuous at fixed points. In this context, we give new results on the fixed-circle ... -
Double perovskite structure induced by co addition to pbtio3: Insights from dft and experimental solid-state NMR spectroscopy
(Amer Chemical Soc, 2019)The effects of Co addition on the chemical and electronic structure of PbTiO3 were explored both by theory and through experiment. Cobalt was incorporated into PbTiO3 during the sol-gel process with the X-ray diffraction ... -
Some theorems of approximation theory in weighted smirnov classes with variable exponent
(Springer Heidelberg, 2020)Let G. C be a Jordan domain with rectifiable Dini smooth boundary G. In this work, we investigate approximation properties of matrix transforms constructed via Faber series in weighted Smirnov classes with variable exponent. ... -
Certain combinatoric convolution sums arising from bernoulli and euler polynomials
(Univ Miskolc Inst Math, 2019)In this study, we introduce the absolute Mobius divisor function U (n). According to some numerical computational evidence, we consider integer pairs (n, n + 1) satisfying; phi (n) = phi (n + 1) = U (n) = U (n + 1). ... -
Calix[4]amine Langmuir-Blodgett thin film sensing properties against volatile organic compounds
(Iop Publishing LTD, 2019)Thin films of CBAMINE were deposited at air-water interface by the method of Langmuir-Blodgett (LB) technique onto a suitable substrate. Atomic force microscopy technique was used to characterize its thin film properties. ... -
A theoretical investigation on the activation of small molecules by a disilenide: A DFT prediction
(Scientific Technical Research Council Turkey-Tubitak, 2019)Herein, we proposed several mechanistic scenarios for activation of small molecules (NH3, CO2, CS2, H-2, CH4, N-2, and N2O) by a disilicon analogue of a vinyl anion (1H) using density functional theory (DFT) calculations. ... -
Fractional order model of immune cells influenced by cancer cells
(Edp Sciences S A, 2019)In this paper, we study the mathematical model of interaction cancer cells and immune system cells presented Castiglione and Piccoli. As the interaction between cancer cells and the immune system is weak, when the immune ... -
Local generalization of transversality conditions for optimal control problem
(Edp Sciences S A, 2019)In this paper, we introduce the transversality conditions of optimal control problems formulated with the conformable derivative. Since the optimal control theory is based on variational calculus, the transversality ... -
