TiO2 foams have been prepared by a simple mechanical stirring method. Short-chain amphiphilic molecules have been used to stabilize colloidal suspensions of TiO2 nanoparticles. TiO2 foams were characterized by X-ray diffraction (XRD). X-ray photoelectron spectroscopy (XPS). https://www.wingdress.com/product-category/mens-underwear/
