    Abstract: In this work Titanium Dioxide thin films were successfully deposited on glass substrates at room temperature by pulsed laser deposition technique (PLD) using a Q-switch Nd: YAG laser to fabricate thin films. The target was an Anatase TiO2 powder that converted to solid disks by compressing it. The disks were irradiated with different laser pulse en... Show More

    Abstract: Hydrogel polymers were prepared via graft polymerization of acrylamide (AAm) onto chitosan (CTS) backbone in the presence of methylene bisacrylamide (MBA) as cross-linker and ammonium persulfate (APS) as an initiator. Optimizing the crosslinking graft reaction of AAm onto CTS was studied by varying the concentration of CTS and MBA cross-linker and ... Show More

    Abstract: The biological active polyurethane (PU) based on diisocyanate prepolymer and folate-lactose (FL) was synthesized. Physical, mechanical and thermophysical properties of polymeric films were investigated. It was found that the value of the strength at break and elongation of PU with FL are higher by 83% and 22% than the corresponding physical and mec... Show More
