Alfa Aesar, a Johnson Matthey Company, has released a brochure titled “Nanoparticles and Dispersions,” which details products from Nanophase Technologies Inc., a supplier of nanocrystalline materials. Along with a diagram, the three-page document discusses the physical vapor and NanoArc synthesis techniques for producing the particles. The former yields particles with sizes ranging from 8 to 75 nm, and the latter, from 7 to 45 nm. Technologies such as discrete particle encapsulation and concentrated, ready-to-use nanoparticle dispersions are covered. The lists of powders and dispersions include descriptions, forms, formulas and catalog pack sizes.
