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 ...
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 ...
