A look on separation axioms in neutrosophic topological spaces
(Amer Inst Physıis, 2021)This study is dedicated to make an attempt to define different types of separation axioms in neutrosophic topological spaces. The relationships among them are shown with a diagram and counterexamples. We also introduce ... -
Separable solutions of Cattaneo-Hristov heat diffusion equation in a line segment: Cauchy and source problems
(Elsevier, 2021)The behavior of Cattaneo-Hristov heat diffusion moving in a line segment under the influence of specified initial and source temperatures has been investigated. The Fourier method has been applied to determine the ... -
New discontinuity results at fixed point on metric spaces
(Springer Basel AG, 2021)Recently, the discontinuity problem at a fixed point has been studied by various aspects. In this paper, we investigate new solutions to the discontinuity problem using appropriate contractive conditions which are strong ... -
First-principles study on structural, electronic, elastic, phonon, and thermodynamic properties of tungsten oxide-based perovskite NaWO3
(Springer, 2021)The structural, electronic, elastic, phonon, and thermodynamic properties of the cubic perovskite structure of the NaWO3 compound were calculated from first-principles studies based on density functional theory (DFT). These ... -
A fractional SAIDR model in the frame of Atangana-Baleanu derivative
(MDPI, 2021)It is possible to produce mobile phone worms, which are computer viruses with the ability to command the running of cell phones by taking advantage of their flaws, to be transmitted from one device to the other with ... -
A new solution to the Rhoades' open problem with an application
(Sciendo, 2021)We give a new solution to the Rhoades' open problem on the discontinuity at fixed point via the notion of an S-metric. To do this, we develop a new technique by means of the notion of a Zamfirescu mapping. Also, we consider ... -
Existence and uniqueness results for a smoking model with determination and education in the frame of non-singular derivatives
(Amer Inst Mathematical Sciences-AIMS, 2021)These days, it is widely known that smoking causes numerous diseases, as well as resulting in many avoidable losses of life globally, and therefore encumbers the society with enormous unnecessary burdens. The aim of this ... -
Metal ion effects on Polyphenol Oxidase Covalently immobilized on a Bio-Composite
(C M B Assoc, 2021)Biosensors can be developed using different immobilization methods. Interest in immobilization methods have increased because biosensors have been important for science. Polyphenol oxidase (PPO) was used generally in ... -
Optimal control of the Cattaneo-Hristov heat diffusion model
(Springer Wien, 2021)In this study, the optimal control problem for Cattaneo-Hristov heat diffusion, a partial differential equation including both fractional-order Caputo-Fabrizio and integer-order derivatives, is formulated for a rigid heat ... -
Biological activities of some Salvia species
(Walter De Gruyter GMBH, 2021)In this study, total phenolic, flavonoid and protein contents, antiradical capacities, antibacterial and cytotoxic properties of five different Salvia species (Salvia macrochlamys Boiss., Salvia kronenburgii Rech.f., Salvia ... -
Adsorption of methylene blue on imine modified sepiolite from aqueous solutions
(Parlar Scientific Publications (P S P), 2021)In this study, a modified sepiolite for methylene blue (MB) adsorption was designed. Modification of sepiolite was performed using N,N-dimethy1-4-(((3-(triethoxysilyl)propyl)imino)methyl)aniline (MESPIA) in the presence ... -
Characterization of activated carbons prepared from almond shells and their hydrogen storage properties
(Amer Chemical Soc, 2021)In this study, activated carbons with a well-developed porous structure and high surface area were prepared from almond shells by chemical activation using zinc chloride and microwave irradiation methods under a nitrogen ... -
