(Wiley, 2020)
In this study, starting from 4-amino-5-(4-chlorobenzyl)-2,4-dihydro-3H-1,2,4-triazole-3-one (1), the 4-Amino-5-(4-chlorobenzyl)-2-undecyl-2,4-dihydro-3H-1,2,4-triazol-3-one (2) was first synthesized and this compound was ...
Microwave assisted synthesis of some novel 2-(3-Chlorobenzyl)-1H-benzimidazole derivatives and determination of their antimicrobial activity and pKa values
(Chiminform Data S A, 2015)
In the present research, synthesis of new 2-(3-chlorobenzyl)-1H-benzimidazole derivatives bearing N-benzylidene, 1,2,4-triazole and N-acylhydrazone moiety is investigated. These novel compounds have been tested for their ...
Microwave-assisted synthesis of some new benzimidazole derivatives with their antimicrobial activity
(Bentham Science Publ Ltd, 2015)
2-(2-Chlorobenzyl)-1H-benzimidazole (2) was prepared from the reaction of o-phenylenediamine and ethylimido-o-chlorophenylacetate hydrochloride (1) under microwave irradiation. the acetate and hydrazide derivatives of 2(2- ...
Simultaneous separation and preconcentration of Cd(II), Co(II), and Ni(II) ions in environmental samples by carrier element-free coprecipitation method prior to their flame atomic absorption spectrometric determination
(Taylor & Francis Inc, 2015)
In the present study, Cd(II), Co(II), and Ni(II) ions were separated and preconcentrated via carrier element-free coprecipitation (CEFC) method by using an organic coprecipitating agent, 1,2-bis-(2-tosyl ethoxy) benzene ...
Determination of epinephrine in human serum using a Pt electrode modified by polyaniline-poly(3-methylthiophene)-poly(3,3 '-diaminobenzidine)
(Canadian Science Publishing, Nrc Research Press, 2015)
A Pt electrode modified by polyaniline-poly(3-methylthiophene)-poly(3,3'-diaminobenzidine) was used for amperometric determination of epinephrine in a solution of NaHSO4/Na2SO4 (pH 2.0). For these studies, potentials between ...

A polyphenol oxidase (PPO) from Cimin grape was purified 11.2-fold by using a Sepharose 4B-L-tyrosine-p-aminobenzoic acid affinity column. the optimum pH and temperature of PPO purified from Cimin grape were 7.5 and 30 ...
Investigation of the behavior of hydrogen-bonded phenolic compounds and their determination by using poly(vinylferrocenium)-polyaniline composite film
(Wiley, 2016)
The hydrogen bonding between phenolic compounds (phenol (Ph), catechol (Ct), resorcinol (Rs), and hydroquinone (Hq)) is investigated at pH 4. the oxidation behaviors of total phenolic compounds (TotPh) are different from ...
Improving the stability of solar cells using metal-organic frameworks
(Royal Soc Chemistry, 2016)
Although Cu2S-containing chalcogenide solar cells are appealing and cost-effective for photovoltaics (PVs), these materials suffer from rapid performance degradation as a result of the diffusion of copper ions into the CdS ...
