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 ...
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: ...
PD-1 and PD-L2 expression predict relapse risk and poor survival in patients with stage III colorectal cancer
(Springer Science and Business Media B.V., 2021)
Background: Immune responses have long been an area of interest in cancer research. In this study, the effects of programmed cell death-1 (PD-1) and its ligand (PD-L2) on the prognosis of colorectal cancer (CRC) were ...
Effect of ultrasound-guided erector spinae plane block on post-surgical pain in patients undergoing nephrectomy: a single-center, randomized, double-blind, controlled trial
(Sage Publications Ltd, 2022)
Objective Erector spinae plane (ESP) block is an alternative to neuraxial block for post-surgical pain in nephrectomy patients. However, no clinical trial has directly compared ESP block with a control group. Methods In a ...
