Appearance of the system(CLICK: Zoom In/Out)Nanosuspension system NS series

The system is possible to generate nanosuspension consist of homogeneous nanoparticles from the surface of original materials by irradiating laser to micro-ordered particles or balk materials in poor solvent.

The nanoparticles size is selectable in the range of dozens of 10 nanometers to dozens of 100 nanometers by changing the process conditions.


Applications

(1)Powders

Nano-atomization process

Nano-atomization processSample: VOPc powder + water + dispersant

1. When color of colorant (VOPc, dozens of micrometer) is stirred in water, the color can not be seen.
2. Irradiating laser to the suspension, the suspension has color of the colorants due to effect of nano-atomization.
3. Keeping laser irradiation and stirring, homogeneous nanosuspension of colorants is obtained.
