Publishing a Patent in Recent Patents in Nanotechnology by a TIU Academic Staff Member

Recently, a group of researchers led by Associated Professor Dr Azeez Abdullah Barzinjy from the Physics Education Department, Faculty of Education, Tishk International University Prof Dr Samir Mustafa Hamad and Vinos Mushir Faris published a patent in Recent Patents in Nanotechnology. Recent Patents in Nanotechnology publishes full-length research articles that reflect or deal with studies concerning a patent. The published patent was entitled: Biosynthesis of Silver Nanoparticles at Various pH Values and Their Applications in Capturing Irradiation Solar Energy. This work was collaboration research between Tishk International University and Soran University.

When the size of nanoparticles is smaller than the wavelength of light, free electrons can be displaced from the lattice of positive ions and collectively oscillate in resonance with the light. This is known as a Localized Surface Plasmon Resonance. Therefore, silver nanoparticles were synthesized in this patent using weeping willow leaf extract. Then, silver nanoparticles have been used to generate heat and increase water temperature from solar radiation energy. The novelty of this patent is that silver nanoparticles can be synthesized from a one-pot reaction without using any exterior stabilizing and reducing agent, which is not conceivable by means of the existing processes. This study is also rare and distinctive, demonstrating that even a slight quantity of Ag NPs can effectively raise the water temperature.
