New Heterocyclic compounds derivatives comprising 1,3-oxazole, chalcone ,thiazole, pyrimidine, quinolone moieties are reported. New derivatives of Quinazolin-4 (3H)-one ring comprising Schiff’s bases,(1,3,4Thiadiazole),(1,3,4-Oxadiazole) and (1,2,4-Triazole), Thiaurease moieties are reported. Compounds (1), (2) and (5) were synthesized by reaction of benzoyl chloride with urea , thiourea and anthranilic acid respectively , then compounds (1)and (2) were converted into(3a-c) and (4a-c) derivatives. While compound ( ...

This study includes the effect of wafer resistivity and intensity of light on topography of porous silicon surfaces which produced by photo chemical etching method, the results showed that changing of the resistivity led to change the porosity, where it found the porous silicon layer be less of high value resistivity. Once all the wafers have same resistivity's value that’s found the light intensity effect on porosity, the less value of porosity produced by the less value of intensity light focused. ...
