The Department of Chemistry at the College of Education for Pure Sciences held an electronic panel discussion entitled (Manufacture of Nano-layers and methods of their use), which was delivered by Asst.Lect. Nahla Jaber Husse. The discussion aimed to explain the method of preparing Dihydroxide Nanolayers and to know the methods of using these layers. The seminar included several axes, including Introduction to nanotechnology, the fields in which nanotechnology enters, what are Dihydroxide Nano-layers, preparation of Dihydroxide Nano-layers by co-deposition method, and uses of Dihydroxid Nano-layers.
