experience

In sept.1982 I was appointed a research assistant in Chemistry Department, College of Science, From that till now I have been working on organometallic compounds. under the auspices of my supervisors Prof. Omar M. Abu-Salah and Dr. Abdel-Razak Al-Ohaly

.  Through out this period I have gained excellent experience in synthesis, identification and chemical reactivity of arylacetylide, cyanide ligands-containing new anionic and cationic clusters of group 11 such as gold, silver, copper and platinum metals. I have studied their (IR), NMR spectroscopy, elemental analyses and their single crystal X-ray crystallography.

I have gained good experience in preparation and filtration techniques under nitrogen atmosphere, vacuum, low temperatures (down to-70C0), high temperatures and at room temperature.

We prepared many of novel complexes anionic, cationic polymers, dimmers, and clusters in novel and unprecedented synthesis

The compounds that I have already prepared were published in refereed scientific journals. These compounds were new and have not been reported before, especially the cationic ones. I have been working as research assistant with Dr.Abdullah S. Al-Arifi in Ziegler-Natta Catalysis and Polymerization.

 Expert in Preparation of Metallocene Compounds and testing their polymerization activity in modern Reactor. Syntheses included the handling  of chemicals in glove-box under nitrogen.                  

Since 1985 till now, I have been appointed operator of (I.R. Spectrometer recently FT-I.R operator for chemistry department. I run samples that are coming from different departments and laboratories. During this time I have gained a vast experience in elucidating structures of compounds especially the organometallic compounds 

Teaching demonstrations experience

Teaching and demonstrations experience on the following:

1-     Practical of general Chemistry (101Chem.).

2- Practical organometallic (428 Chem.) for long time.

Acknowledged M.Sc. degrees:

I have been acknowledged in 6 Master degrees (M.Sc.) for technical assistance on the following:
