Publikováno v: Molecules, Vol 26, Iss 20, p 6312 (2021)
The present work aimed to assess six diaryl sulfide derivatives as potential corrosion inhibitors. These derivatives were compared with dapsone (4,4′-diaminodiphenyl sulfone), a common leprosy antibiotic that has been shown to resist the corrosion

The anti-corrosive behavior of benzo-fused N-heterocycles: an in silico study toward developing organic corrosion inhibitors
Autor: Morad M. El-Hendawy, Asmaa M. Kamel, Mahmoud M. A. Mohamed
Publikováno v: Physical Chemistry Chemical Physics. 24:743-756
The gradual introduction of nitrogen atoms is not a straightforward factor in controlling the inhibition efficiency of BFNH inhibitors. For example, phthalazine (Phz) is a better inhibitor than benzo[e][1,2,3]tetrazine (Btr).

Mechanistic insights on the catalytic hydrogenation of cyclohexene by ruthenium(III) N2O2 tetradentate Schiff-base complex
Autor: Morad M. El-Hendawy, Mohamed M. Ibrahim, Abd El-Motaleb M. Ramadan
Publikováno v: International Journal of Hydrogen Energy. 46:39786-39798
The work aimed at the mechanistic investigation of the catalytic hydrogenation of cyclohexene by a newly synthesized ruthenium(III) Schiff base complex, [RuLCl(H2O)], where L represents tetradentate N2O2 naphthaldiimine. Several physicochemical metho
