Optimization of vortex-assisted switchable hydrophilicity solvent liquid phase microextraction for the selective extraction of vanillin in different matrices prior to spectrophotometric analysis
(Elsevier, 2023)
The main purpose of this research article is to develop a vortex-assisted switchable hydrophilicity solvent liquid phase microextraction (VA-SHS-LPME) for the selective and efficient extraction of trace vanillin in food ...
Optimization of vortex-assisted hydrophobic magnetic deep eutectic solvent-based dispersive liquid phase microextraction for quantification of niclosamide in real samples
(Elsevier, 2023)
In this manuscript, a green and fast vortex-assisted hydrophobic magnetic deep eutectic solvent-based dispersive liquid phase microextraction (VA-HMDES-DLPME) method was developed for the selective extraction and determination ...
Determination of trace cobalt (II) in spices samples by ultrasonic assisted cloud point extraction with spectrophotometry
(JOURNAL OF MOLECULAR STRUCTURE, 2023)
In this study, ultrasonic assisted cloud point extraction (UA-CPE) method was developed for the determination of Cobalt (II) (Co(II)) in spices. After extraction and preconcentration, the Co(II) contents of the samples ...
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 ...
Analysis of boronic acids containing amino ferrocene by DFT approach and in silico studies
(Elsevier, 2023)
The synthesized (2)-(6) complexes and (2′)-(6′) hypothetical complexes formed by attached boranic acid esters were optimized at the DFT-B3LYP/GEN level. The structural and spectroscopic properties (IR, 1HNMR , 13CNMR ) of ...
In Silico and In Vitro Studies of Novel Azomethines on DNA Repair Genes in Gastric Cell Lines
(MDPI, 2023)
We herein report the determination of the cytotoxic activity and expression profiles of some DNA repair genes of newly synthesized azomethines in the gastric cancer cell line (AGS). The studied novel compounds were synthesized ...
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 ...
