Abstract :
Different kind of nanometric powders: carbon, iron, titanium, silicium, oxides and composites, obtained by laser pyrolysis have the ability to float on water. In analogy with Langmuir-Blodgett deposition technique, thick films were formed on substrates. If water contains ionic salts, single-crystals of micrometric size crystallize onto the surface.
