Investigations substituent effect on structural, spectral and optical properties of phenylboronic acids
(2021)
Ortho- and para-substituent arylboronic acid are investigated. Geometric structure and structural proper- ties of these compounds are done. IR and NMR spectrum are calculated for the spectral characterizations. Contour ...
Experimental and in silico studies of dichloro- tetrakis (1H-pyrazole)-cobalt(II): Structural description, photoluminescent behavior and molecular docking
(2021)
A novel pyrazole-based Co(II) complex, namely dichloro-tetrakis(1H-pyrazole)-cobalt(II), was synthesized
and characterized. Its X-ray crystal structure showed that it crystallizes in the monoclinic C 2/ c space
group ...
Scale factor database for the vibration frequencies calculated in M06-2X, one of the DFT methods
(2021)
Vibrational scale factors were determined for the M06-2X method. The calculated scale factors were supported
statistically. The main objective is to determine the concordance between frequencies. Descriptive statistics ...
Ultrasonic-assisted cloud point microextraction and spectrophotometric determination of Ponceau 4R in various beverage samples using Non-ionic surfactant PONPE 7.5
(Taylor & Francis, 2021)
In the current study, a simple, cheap, and fast analytical procedure, termed ultrasonic-assisted cloud point microextraction (UA-CPME), combined with UV-VIS spectrophotometry, was developed for the pre-concentration and ...
pH-controlled charge transfer sensitive 2-aminobenzimidazole modified poly(styrene-co-maleic anhydride) copolymer for selective extraction, pre-concentration and determination of trace Hg2+ and CH3Hg+ in vinegar by combination of ultrasound assisted-cloud point extraction with UV-VIS spectrophotometry
(2022)
In this study, a separation/pre-concentration procedure, ultrasound assisted-cloud point extraction with modified
2-aminobenzimidazole (2-ABzI), was developed for the extraction of trace Hg2+ and CH3Hg+ and from
vinegar ...
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 ...
Molecular docking and A DFT study on the antiradical activity of naringenin and hesperetin with nitric oxide, peroxy, and methoxy radicals
(2023)
Naturally occurring flavonoids, naringenin (N) and hesperetin (H), weretheoretically investigated for their ability to scavenge nitric oxide, peroxy,and methoxy radicals in gas, water, and benzene solvent ...
