At the beginning of my career and as a demonstrator I was responsible for updating the physical chemistry labs to fulfill the requirements of the major chemistry program and the introduction of new experimental techniques in physical chemistry on the undergraduate level. During the M.Sc. work I have proved that Sodium Tungsten Bronze electrodes cannot be used as oxygen electrodes for fuel cells as was claimed, which was an important achievement at that time. Due to my activities at the CairoUniversityon both scientific and community service, I got a Ph.D. Fellowship at the Technical University of Merseburg , Germany, where I did my Ph.D. in the field of applied electrochemistry (non-aqueous solution electrochemistry) in an optimum time. I have transferred the new technology of electrodeposition and dissolution of metals from non-aqueous solutions and mixed solvents to the CairoUniversitywhere some theses and papers were published in this field. During the Max-Planck Society Fellowship (81-83), I have introduced the spray/pyrolysis technique to prepare thin oxide films for solar cell fabrication and testing lab., and then established this technique later at the CairoUniversityand was the first to introduce the solar energy conversion research and courses to our university. During this intensive work I could formulate and introduce the concept of separating the solid state photovoltaic junction from the site of electrochemical reaction at the oxide/electrolyte interface (Solid/Electrolyte junction). At the same time my group and my self could succeed to modify thin oxide film characteristics to match photovoltaic and photoelectrochemical solar energy conversion. I have established a school of research in this field (over 8 theses and more than 40 publications). I could establish an electrochemical lab at the CairoUniversitythrough gifts and help of the Fritz- Haber-Institut ( Professor Heinz Gerischer ) in Berlin. This lab was complimented with up to date Impedance system as gift for my excellent work during the Alexander von Hombuldt Fellowship at the Free University of Berlin. The work is extended to the semiconductor electrochemistry, corrosion and corrosion control problems. I have transferred his knowledge to the students at the CairoUniversity, Sana’a University in Yemenand also at the Universityof Kuwaitand established electrochemistry research groups everywhere. Due to the rich scientific accomplishments and publictions I was invited to write a Monograph in one of the most important scientific series in electrochemistry "Modern Aspects of Electrochemistry ", ( JO' M Bockris, B. Conway & R. White- Eds.) on the solar energy conversion, photovoltaic and photoelectrochemical cells, which appeared in the 30th volume of the series in Dec.,1996. Many review articles concerning corrosion and corrosion inhibition of industrially valuable materials like Al and its alloys, brass and some environmentally and biologically hazardous metals like Cd and Pb have been published and have good impacts on the international scvientific community (see list of publicatiobn). In 2002, I got the
d and honoured with the
and at the same time nominated from the Cairo University to the State Recognition Prize in Applied Sciences, and then got the "
I was the referee and still refereeing many article for different international journals e.g, Electrochim. Acta , J. Electrochem.Soc., J.Appl.Electrochem., J. Materials Sci., Solar Energy Materials, Solar Cells, corrosion nace and corrosion science. I am refereeing different theses from various universities on a national and international scales and also different projects.
