The researcher discovered the effects of coating 70-nanometer Terbium film between two layers of cadmium sulfide on structural, optical and electrical properties. X-ray diffraction, electronic microscopy scanning, X-ray dispersion, class analysis and electro-thermal technology were used to study these effects. Pointing, coating Terbium fill with two layers of 500-nanometer cadmium sulfide enhances the structural nature of the films without altering their structural constants.

In her thesis, she mentioned the regulations for foreign firms, compared the three legislations of Palestinian, Jordanian and Egyptian and she merely addressed some legal texts in Lebanon, Emirates and Qatar which deal with the existence of such firms in their countries.

She concluded, for their sake all countries especially the developing ones, should have foreign companies within their lands to benefit from it; more manpower employment and advancement at all levels especially the economic and technological levels.

In his thesis, he explored some of the bismuth zinc niobium oxide ceramic composed with lanthanum characteristics, due to its famous high insulation application. Lanthanum concentration was changed in the range x =0.10 – x =0.22. X-ray diffraction analysis showed that ceramics grow individually from 33 – 57 nm when lanthanum concentration increases from 0.10 – 0.20.
