Synthesis and characterization of silica nanospheres using nonsurfactant template
In the present work monodispersed silica spheres were successfully synthesized using nonsurfactant approach of neutral palm oil derived fatty alcohols based microemulsions. The resulting silica spheres have diameter in two size clusters; ca. 560 nm and ca. 700 nm, respectively. The synthesis was aco...
