The current study has investigated the reaction of ascorbic acid with azure A chloride salt dye spectrophotometrically by following the absorbance decline of azure A chloride salt at 630 nm in the presence and absence of a non-ionic micelle of the natural surfactant (N-dodecyl β-D-glucopyranoside). Thus, the primary aim was to examine the influence...

A library of novel benzamide‐thiazolyl‐chalcone compounds was synthesized via Claisen‐Schmidt reaction and spectroscopically characterized using FT‐IR, ¹H‐NMR, ¹³C‐NMR, LC–MS, and HR‐MS. The synthesized compounds were biologically evaluated using in vitro MTT assay against different cancer cell lines (MCF‐7, MDA‐AMB‐231, Caco‐2, A549, and H1299). A...

The influence of nonionic surfactant micelles such as Tween 80, polyethylene glycol 400, and coco glucoside on the inhibition of aluminum corrosion in hydrobromic acid solutions was investigated via weight reduction, thermometric, and electrical conductivity techniques. In the absence of inhibitors, the rise in temperature and acid levels has led t...

Weight-loss, thermometric, and electrical conductance techniques were employed for the investigation of the influence of polyethylene glycol 400, 4000, and polyvinylpyrrolidone K15 as cost-effective, efficient, and eco-friendly inhibitors on the corrosion inhibition of copper in H2SO4 solution. The corrosion rates of copper in H2SO4 solutions incre...

Tri-, tetra-bromothiophene and symmetrical dibromo-2,2'-bithiophene derivatives were coupled efficiently with cyclohexylmagnesium bromide in the presence of iron, nickel and palladium as catalysts under optimized mild reaction conditions. Additives such as lithium chloride and bromide were employed to enhance the efficiency of the Grignard reagent....

The reaction kinetics of catechol or resorcinol with cerium (Ce) ammonium sulfate were spectrophotometrically investigated in polymer media containing polyethylene glycol (PEG 200, 600, 1500, and 4000). Kinetic runs for Ce(IV) were performed under pseudo-first-order reaction conditions. The reaction was found to be first-order for Ce(IV) and fracti...

Kinetics of the reaction of maltose with cerium ammonium sulfate were analyzed spectrophotometrically by observing the decrease of the absorbance of cerium (IV) at 385 nm in the presence and absence of polyethylene glycols (600, 1500, and 4000) and polyvinylpyrrolidone (PVP), in addition to anionic micelles of sodium dodecyl sulfate (SDS), cationic...

The kinetics of the oxidation of o-Cresol by cerium(IV) have been investigated spectrophotometrically at 298K in the absence and presence of sodium dodecyl sulfate (SDS) and polyethylene glycols (PEGs) in sulfuric acid medium to examine the catalytic behavior of SDS, PEG (600, 1500, and 4000), and the mixed systems of PEG 600, 1500, and 4000 with S...

In this study eight selected of the most potent cyclin dependent kinase 2 inhibitors in which targeting adenosine triphosphate -pocket site theoretically investigated to support literature information of frontier molecular orbitals, molecular electrostatic maps, and global chemical reactivity descriptors such as chemical hardness, chemical softness...

Kinetics of the oxidation of both salicylic acid and acetylsalicylic acid by colloidal manganese oxide (MnO2) have been explored spectrophotometrically by monitoring the decay in the absorbance of colloidal MnO2 at 390 nm in absence and presence of surfactants and polymers. The major goal of this research is the study of the effect of the nature of...
