The aim of this study was to evaluate the efficiency of polyurethane foam containing silver nanoparticles synthesized by Verbena officinalis leaf extract in controlling of Yersinia ruckeri in treatment of water tanks of rainbow trout farming. Biosynthesis of silver nanoparticles is done with 2mM silver nitrate solution and Verbena officinalis extract. To study antibacterial effects of the produ...

A new method for the synthesis of lignin-based liquid polyols was developed. Organosolv lignin reacted with ethylene carbonate in polyethylene glycol as solvent, leading to a full conversion phenolic OH into primary aliphatic groups. These aromatic are obtained single step, without any purification. Upon modification molar mass, wide range hydroxyl values (IOH) can be covered. The up 30%wt have...

The purpose of this study was to fabricate and investigate the highly porous structure using titanium dioxide, which is a candidate for bone defect repairing. For this purpose, TiO2 scaffolds were synthesized using titanium butoxide, Pluronic F127 surfactant, and polyurethane foam blocks. Therefore, a colloid includes titanium butoxide and F127 and the polyurethane foams were immersed in it. Th...
