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 ...
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 ...
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 ...
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 ...
A new approach to the total synthesis of (±)-nordasycarpidone by ring-closure with tetrachloro-1,4-benzoquinone
(Macedonian Journal of Chemistry and Chemical Engineering, 2020)
new synthetic route for the (±)-nordasycarpidone was achieved in five steps with an overall yield of 41 %. This route involves ring closure and formation of 5 which has a methanoazocino[4,3-b]indole skeleton in the key ...
Sol-gel derived ZnO:Sn thin films and fabrication of n-ZnO:Sn/p-Si heterostructure
(Elsevier B.V., 2021)
In this work ZnO:Sn thin films were deposited onto glass and p-Si substrates by spin coating of prepared sols which contains different amounts of Zn(CH3COO)2·2H2O and SnCl2 (0, 5, 10 and 15%). Physical properties of ZnO ...
Generic hybridity in Hanya Yanagihara's A Little Life
(Routledge, 2022)
This article explores the use of contrasting features from diverse literary genres in Hanya Yanagihara’s second novel A Little Life, published in 2015 and shortlisted for the Man Booker Prize. These contrasting features ...
Illumination and voltage effects on the forward and reverse bias current-voltage (I-V) characteristics in In/In2S3/p-Si photodiodes
(Springer, 2021)
The illumination and voltage effects on the I-V measurements of the fabricated In/In2S3/p-Si photodiode were investigated in dark and under various illumination intensities (20–100 mW/cm2) between ± 2 V. Two linear regions ...
