Chementator: This new crystallizer reduces damage to larger crystals

With the exception of Oslo-type crystallizers, the main commercial crystallizers are agitated systems that use an agitator [agitated tank or draft-tube baffle (DTB)] or a circulation pump [forced circulation (FC) crystallizers]. In such systems, however, large crystals become damaged by…

Chementator: Sonopolymerization as a means to manufacture composite nanoparticles

Many methods have been developed for the encapsulation of "active" materials within a carrier nanoparticle, such as a polymer. These composite structures can be used in many biomedical, cosmetics, and food processing applications for the controlled release of pharmaceuticals, neutraceuticals,…
