Structural, Microstructural and Electrochemical Studies of Co/Mn Derived Oxides as Protective Layers for Intermediate Temperature SOFCs

Autor: Taha Mattar, Salwa M. Mohamed, M.F. El-Shahat, Mostafa M.M. Sanad

Publikováno v: Key Engineering Materials. 835:353-358

Designing highly protective and superior electrically conductive coatings from Cobalt-manganese doped/un-doped oxide materials (CMOs) is the main target of this study. The as-prepared nanopowders were synthesized via glycine nitrate process (GNP) at

Comparison between Different Techniques in Purification of 18O Enriched Water after Cyclotron Irradiation

Autor: M.F. El Shahat, A. S. El-Kholany, M. S. Masoud

Publikováno v: The International Conference on Chemical and Environmental Engineering. 9:295-306

In the synthesis of 18F-FDG by nucleophilic substitution method, 18O-H2O is usually used as target water. The high cost of virgin 18O-H2O enriched water pointed to recycle process after the first irradiation for the production of radiopharmaceuticals

Electroslag Refining of CrNiMoWMnV Ultrahigh-Strength Steel

Autor: Jukka Kömi, Mohammed Ali, Hoda El Faramawy, Taha Mattar, M.F. El-Shahat, David Porter, Mamdouh Eissa

Publikováno v: Journal of Minerals and Materials Characterization and Engineering. :385-407

Increasing demands for ultrahigh-strength steels in commercial as well as military applications have raised interest in finding alternatives to the high-cost high-alloyed steel and super-alloys currently used, e.g. the use of economic low-alloy compo

Equilibrium, kinetic and thermodynamic studies of the removal of triphenyl methane dyes from wastewater using iodopolyurethane powder

Autor: M.F. El-Shahat, E.A. Moawed

Publikováno v: Journal of Taibah University for Science. 10:46-55

The removal and recovery of rosaniline and brilliant green were studied using batch and dynamic processes. The maximum sorption of these dyes (∼100%) was obtained in a pH range of 6–10 with a shaking time of 2–5 min. The sorption kinetics were

Solid-phase extraction of Cu, Zn, and Mn from Nile river and tap water prior to flame atomic absorption determination

Autor: S.M. Attaf, S.M. Abdel Azeem, M.F. El Shahat

Publikováno v: Desalination and Water Treatment. 57:21893-21903

In this study, we preconcentrated Cu, Zn, and Mn from Nile river and tap water at Cairo City (Egypt) by solid-phase extraction prior to flame AAS determination. Diacetylmonoxime functionalized silica gel (DMO-SG) was used as sorbent for preconcentrat
