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 ...
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 ...
A NEW REAGENT FOR EFFICIENT SYNTHESIS OF NITRILES FROM ALDOXIMES USING METHOXYMETHYL BROMIDE
(Editura Acad Romane, 2019)
This study outlines an efficient, high-yielding, and rapid method by which to access diverse nitriles from aldoximes with methoxymethyl bromide (MOM-Br) in THF. It represents the first application of MOM-Br as a deoximation ...
Fetal Tracheal Occlusion Increases Lung Basal Cells via Increased Yap Signaling
(Frontiers Media Sa, 2022)
Fetal endoscopic tracheal occlusion (FETO) is an emerging surgical therapy for congenital diaphragmatic hernia (CDH). Ovine and rabbit data suggested altered lung epithelial cell populations after tracheal occlusion (TO) ...
Effect of the COVID-19 pandemic on barriers to middle-aged adults' participation in physical activity in Turkey: a cross-sectional study
(Imr Press, 2022)
Background: Physical inactivity is one of the greatest problems facing the world today. The purpose of this study was to examine the level of barriers to physical activity for middle-aged adults during the COVID-19. Methods: ...
