Elaboration of boehmite nano-powders by spray-pyrolysis
(Elsevier B.V. Sa, 2009-03-05)
Boehmite (gamma-AlOOH) synthesis have been investigated using a spray pyrolysis (SP) device starting from a stable sol of Al-tri-sec-butoxide peptized by nitric acid. Free spherical particles from 100 to 500 nm have been ...

The modification of structural and optical properties of nano- and submicron ZnO powders by variation of solvothermal syntheses conditions
(Springer, 2014-10-01)
Nano- (30-60 nm) and submicron (100-350 nm) ZnO particles were synthesized using solvothermal method at 200 degrees C from an ethanolic solution of zinc acetate dihydrate, applying different reaction conditions, i.e., pH ...
