Synthesis and study of antitumor activity of some new 2-(4-methoxybenzyl)-1h-benzimidazole derivatives bearing triazole, oxadiazole and ethanol moiety
(Editura Acad Romane, 2016)
A series of novel 1,2-disubstituted benzimidazole derivatives containing hydrazinecarbothioamide (7a-c), 1,2,4-triazole (8a-c) and 1,3,4-oxadiazole (5) moiety were synthesized starting from 2-(4-methoxybenzyl)-1H-benzimidazole. ...
Spectroscopic, electrochemical, theoretical characterization and biological evaluation of a ferrocenyl-substituted unsymmetric azine ligand and its Cu(II) complex
(Taylor & Francis Ltd, 2016)
Ferrocenyl-substituted unsymmetrical azine and its Cu(II) complex were prepared. the redox active ferrocene-based azine was obtained by condensation of 1-[(E)-hydrazono]-5-bromo-2-hydroxybenzene with ferrocene carboxaldehyde. ...
Substituted phthalocyanines and their electropolymerization properties
(Elsevier Science Sa, 2016)
In this study, new metal-free and metallo-phthalocyanine complexes (Co, TiO) were synthesized using a piperazine-substituted phthalonitrile derivative. All proposed structures were supported by instrumental methods. ...
Purification and characterization of a polyphenol oxidase from cimin grape (Vitis vinifera spp., Cimin)
(Research Journal Biotechnology, 2016)
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 ...
