New technique uses household humidifier to create nanocomposite materials

ntrifuge. The entire formation process takes only a few seconds.

"Each tiny droplet serves as its own microscopic chemical reactor," Suh said. "The micron-size mist results in particles a few hundred nanometers in size."

Among the materials the chemists have created with their ultrasound induced mists are porous nanospheres that could be useful for catalytic reactions, and encapsulated nanoparticles with potential drug delivery applications. They also have formed metal balls within ceramic shells, reminiscent of decorative, hand-carved concentric ivory spheres from China. The nested nanoballs could prove useful as molecular sieves.
