A new pre-concentration procedure based on poly(styrene-co-maleamide and imide) copolymers modified with 2-hydrazinobenzothiazole prior to spectrophotometric monitoring of inorganic as (as As(III)) in edible vegetable oils
(Elsevier, 27 Decembe)
This study describes the development of 2-hydrazinobenzothiazole modified-amide/imide co-polymers for the extraction/pre-concentration of trace As(III), from edible vegetable oils. Their characterization was realized by ...
Novel amide- and imide-co-polymers modified with sulfathiazole as efficient chelator for selective extraction, pre-concentration and determination of trace inorganic antimony (as Sb(III)) from edible vegetable oils by ultrasound assisted-cloud point extraction coupled to micro-volume UV-spectrophotometry
(Elsevier, 22 Septemb)
The study described the synthesis, characterization, and application of newly prepared sulfathiazole-modified amide/imide co-polymers for the extraction of trace Sb(III) from edible vegetable oils. The method was based on ...

A pH-dependent CT sensitive method for detection of trace Mn in milk by UV-spectrophotometry
(1 Septembe)
In this study, a new method was developed for the extractive pre-concentration/detection of trace Mn in milk prior to analysis by UV-spectrophotometry. The method is based on the pH-controlled intra-ligand charge transfer ...
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 ...
