Omicron: Emergence, Detection, and Response
(Nova, 2023)
COVID-19 pandemic emerged in December 2019, and it is still a global threat with quite a few variants. The B.1.1.529, Omicron, identified in South Africa in 2021, was one of the most notorious variants due to its high ...
An air-assisted dispersive liquid phase microextraction method based on a hydrophobic magnetic deep eutectic solvent for the extraction and preconcentration of melamine from milk and milk-based products
(Elsevier, 2023)
In the current research, a fast and sustainable air-assisted hydrophobic magnetic deep eutectic solvent-based dispersive liquid phase microextraction followed by UV–Vis spectrophotometry measurements was optimized for the ...
Improved carbon steel corrosion characteristics in static and hydrodynamic HCl media by two novel N2O2 ligands: Experimental and theoretical studies
(2023)
Background: Expanding the use of carbon steel in various industrial operations is always associated with challenges
due to many engineering factors in the selection of materials. However, carbon-steel corrosion is a ...
Synthesis, nanostructuring and in silico studies of a new imine bond containing a macroheterocycle as a promising PBP-2a non-b-lactam inhibitor
(2023)
This study is devoted to the synthesis of a 40-membered macroheterocycle with its further
nanostructuring by magnetite nanoparticles. The mentioned macroheterocycle was synthesized by the
[2+2] cyclocondensation of the ...
[Cu 2 (ox)(dien) 2 ](NO 3 ) 3 , a precursor for preparation of CuO nanoparticles: Synthesis, structural, Hirshfeld surface analyses, and physico-chemical investigations
(2023)
[C u 2 ( ox )( dien ) 2 ](NO 3 ) 3 with (ox = oxalate, dien = diethylenetriamine) has been synthesized and charac- terized by single-crystal X-ray diffraction as well as FTIR and UV–Vis spectroscopic techniques. The complex ...
New azo-azomethine based copper(II) and zinc(II) complexes: Synthesis, electrochemistry, photoluminescence properties, density functional theory calculations and molecular docking
(2023)
A new bidentate azo-azomethine ligand 2-{(E)-[(3,4-dimethylphenyl) imino]methyl}-4-[(E)-(4-ethylphenyl)diazenyl]
phenol (2) and its copper(II) and zinc(II) complexes (3) and (4) were synthesized and characterized by
elemental ...
Eaton's reagent is an alternative of PPA: Solvent free synthesis, molecular docking and ADME studies of new angular and linear carbazole based naphtho naphthyridines
(2023)
An approach towards the preparation of novel angular and linear carbazole based naphtho naphthyridines
are described in good yields. From schematic study on the condensation of 4-chloro-2-
methylbenzo[h]quinoline and ...
Crystal Structure, Hirshfeld Surface Analysis, In-Silico and Antimycotic Investigations of Methyl 6-methyl-4-(4- nitrophenyl)-2-oxo-1,2-dihydropyrimidine-5-carboxylate
(2023)
Herein, we report the preparation of methyl 6-methyl-4-(4-nitrophenyl)-2-oxo-1,2-
dihydropyrimidine-5-carboxylate 2, obtained by the regioselective oxidative dehydrogenation of
the dihydropyrimidine derivative 1 in the ...
Corrosion inhibition of Carbon Steel using a new morpholine-based ligand during acid pickling: Experimental and theoretical studies
(2023)
Here, a novel, relatively inexpensive Schiff base ligand (HL) has been studied as a corrosion inhibitor for the
protection of steel in acidic solution. Different concentrations (0–25 ppm) of HL were added to the test ...
Crystal structure, Hirshfeld surface analysis, computational and antifungal studies of dihydropyrimidines on the basis of salicylaldehyde derivatives
(2023)
We herein reported the synthesis of dihydropyrimidines 1 and 2 on the basis of nitro and brominated salicylaldehyde derivatives
by Biginelli reaction in microwave conditions in the presence of cheap low toxic copper ...
