Determination of total flavonoid content by aluminum chloride assay: A critical evaluation
(
Elsevier
, 2021 , Article)
Flavonoids are important natural bioactive compounds. Quantitation of total flavonoid content (TFC) is widely performed using the aluminum chloride colorimetric assay against a flavonoid standard assuming equal responses ...
Continuous adsorptive removal of glimepiride using multi-walled carbon nanotubes in fixed-bed column.

Springer
, 2021 , Article)
Water pollution by emerging pollutants such as pharmaceutical and personal care products is one of today's biggest challenges. The presence of these emerging contaminants in water has raised increasing concern due to their ...
Synthesis of Novel Aqua ƞ4-NNNO/Cu(II) Complexes as Rapid and Selective Oxidative Catalysts for O-Catechol: Fluorescence, Spectral, Chromotropism and Thermal Analyses
(
MDPI
, 2021 , Article)
A new tetradentate Schiff base (SB), (E)-4-fluoro-2-(1-((2-(piperazin-1-yl)ethyl)imino)ethyl)phe-nol, was synthesized from condensation of 2-(1-piperazinyl)ethylamine and 5-fluoro-2-hydroxyacetophe-none. This ligand was ...

(
Springer
, 2021 , Article)
Three neutral Cu(II)/ƞ4-NNNO Schiff base complexes (1-3) were prepared from the (E)-4-nitro-2-(((2-(piperazin-1-yl)ethyl)imino)methyl)phenol, tetradentate Schiff base (SB) ligand, and the corresponding copper(II) salts. ...
Kinetics of alizarin dye hydrolysis in alkaline medium for wastewater treatment
(
Iranian Institute of Research and Development in Chemical Industries (IRDCI)-ACECR
, 2021 , Article)
The kinetics of the hydrolysis of Alizarin dye (ALZ) in the basic medium is investigated for the purpose of wastewater treatment. ALZ represents a group of aromatic dyes, that are heavy, toxic, and non-biodegradable. The ...
XRD/HSA, noncovalent interactions and influence of solvent polarity on spectral properties of dithiocarbazate schiff base and its cis-Cu(II) complex: Experimental and theoretical studies
(
Elsevier
, 2021 , Article)
A N,S-bidentate ligand (LH) was synthesized via the condensation of S-benzyldithiocarbazate with acetophenone. The produced Schiff base ligand was reacted with a copper(II) salt to yield a neutral cis-Cu(II) complex. The ...

A simple and efficient protocol allows the oxidation of the cyclopentadiene derivative 5H-dibenzo[e,h]-dibenzo[3,4 : 6,7]cyclohept[1,2-a]azulene (CpCH) provide according ketone CpCO. Comparable to the situation found for ...
Diversity of arbuscular mycorrhizal fungi and its chemical drivers across dryland habitats
(
Springer
, 2021 , Article)
Qatar is largely characterized by a hyper-arid climate and low soil fertility which create a stressful soil environment for arbuscular mycorrhizal (AM) fungi. In a study of AM fungal communities and their relationship with ...
