This project involves the studying of both optical and electrical properties for the poly methyl methacrylate/zinc oxide composite. These materials were selected because they have an industrial applications and available in local market.Zinc oxide powder with different concentration (4, 8, 10 and 12) % from the total weight was mixed carefully with PMMA.
The target of this research is to prepare nano silver particles by laser ablation in both deionized and magnetized water. The properties of nano silver particles and their bacterial effects with different parameters’ were studied. The magnetic water was laboratory preparing by square magnets with magnetic flux of 200 mT applied on the deionized water which pass through it 10ns Q.swiched Nd-YAG laser of wave length 1064nm with different energies and different laser pulses number were used with and without applied electric field.
Spinel-Aluminum composites are drawing greater attention due to their low density, excellent physical, mechanical and refractory properties. This work aims to study the preparing one of the most current conventional technique and sintering behavior of Spinel-Al composite through characterization of the physical, mechanical properties as well as XRD and microstructure of the synthesis Spinel-Al composite specimens.
