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 ...
Growth and Characterization of Stoichiometric Cu2ZnSnS4 Crystal Using Vertical Bridgman Technique
(John Wiley and Sons Inc, 2022)
Stoichiometric Cu2ZnSnS4 (CZTS) single phase crystals are successfully grown in a single-zone vertical furnace by Bridgman technique. X-ray diffraction (XRD) and Raman spectroscopy measurements are employed to investigate ...
