Computation of eigenvalues and eigenfunctions of a non-local boundary value problem with retarded argument
(Taylor and Francis Ltd., 2021)
In this study, we proved the simplicity of eigenvalues and obtained asymptotic formulas for eigenvalues and eigenfunctions of second order non-local boundary-value problems with retarded argument. © 2021 Informa UK Limited, ...
Spectrum, trace and nodal points of a sturm-liouville type delayed differential operator with interface conditions
(Rocky Mountain Mathematics Consortium, 2021)
A formula for regularized sums of eigenvalues of a Sturm–Liouville problem with delayed argument at the point of discontinuity is obtained. Moreover, nodal points of the related problem are investigated. © Rocky Mountain ...
Supercapacitor performances of RuO2/MWCNT, RuO2/Fullerene nanocomposites
(Wiley, 2019)
In this study, RuO2/Fullerene and RuO2/MWCNT nanocomposites were synthesized to use as an electroactive materials in symmetric supercapacitor device performances. The materials were examined via Fourier transform infrared ...
Synthesis, characterization, and supercapacitor performances of activated and inactivated rGO/MnO2 and rGO/MnO2/PPy nanocomposites
(Springer, 2020)
In this study, a ternary nanocomposite of reduced graphene oxide (rGO), manganese dioxide (MnO2), and polypyrrole (PPy) was synthesized and characterized and presented electrochemical performances of supercapacitor devices. ...
High power density supercapacitor devices based on nickel foam-coated rGO/MnCo2O4 nanocomposites
(Springer Science and Business Media Deutschland GmbH, 2020)
New nanocomposite electrode material of rGO/MnCo2O4 was freely loaded on flexible substrate on nickel foam and prepared by a simple, cost-effective, and eco-friendly pathway. The results show that the spinel manganese ...
Development of a gold nanoparticles-based colorimetric sensor for the indirect determination of ammonium dinitramide and tetryl
(Elsevier B.V., 2021)
Ammonium dinitramide (ADN) is a strong, environmentally friendly oxidizer used in composite solid rocket propellants. As there is no reliable colorimetric sensor for ADN assay applicable to in-field screening, we developed ...
The synthesis and spectroscopic characterization of (+)-demethoxyaspidospermine: Density functional theory calculations of the structural, electronic, and non-linear optic and spectroscopic properties
(SAGE Publications Ltd, 2019)
(+)-Demethoxyaspidospermine was synthesized via the acylation of aspidospermidine with acetic anhydride, and the structure was determined by elemental analysis and Fourier-transform infrared and nuclear magnetic resonance ...
Electrochemical determination of boron using the signal suppression of mannitol on a gold nanoparticle coated p-Aminothiophenol polymer electrode
(Elsevier Inc., 2021)
In this study, a glassy carbon electrode (GCE) modified with gold nanoparticles (AuNPs) and coated with electropolymerized p-aminothiophenol (p-ATP) was used as a modified electrode (GC/AuNPs/PATP electrode) for the indirect ...
Amperometric Biosensors for Tyramine Determination Based on Graphene Oxide and Polyvinylferrocene Modified Screen-printed Electrodes
(Wiley-VCH Verlag, 2019)
A comparison of the analytical characteristics of two tyramine biosensors, based on graphene oxide (GRO) and polyvinylferrocene (PVF) modified screen-printed carbon electrodes (SPCE), is reported. Diamine oxidase (DAOx) ...
Magnetite nanoparticles-based hydroxyl radical scavenging activity assay of antioxidants using N, N-dimethyl-p-phenylenediamine probe
(Scientific Technical Research Council Turkey-Tubitak, 2020)
Excessive amounts of reactive oxygen species (ROS), unless counterbalanced by antioxidants, can cause cellular damage under oxidative stress conditions; therefore, antioxidative defenses against ROS must be measured. With ...
