Because of its expertise in inorganic chemistry (rare earths, silicas, zirconium, titanium), Rhodia has regularly developed nanoparticle systems (with particle diameters typically between 5 and 100 nanometers) for more than 10 years. Fields of application vary from tires and cosmetics to plastics and coatings or catalysis/filtration. This knowledge has been adapted to coatings technologies, especially for organic transparent coatings, such as those used in wood coatings.

Catalyst eliminates diesel NOx emissions
Tribology & Lubrication Technology
; Regulation of NOx emissions from diesel engines is continuing with the enforcement of the EPA's new requirement of 1.2 grams per brake hp hour in 2007. This represents a 90% reduction in diesel emissions since the previous standard (2 grams per brake hp hour) was enacted in 2004. Tougher emission

New catalyst helpful in reducing NOx diesel emissions
Tribology & Lubrication Technology
; The establishment by EPA of new NO emission requirements for diesel engines in 2007 is prompting research to determine how to most effectively meet these requirements. EPA's standard reduces NO emissions from 2 grams per brake hp hour in 2004 to 0.2 grams per brake hp hour in 2007. This represents

Preparation of Enriched Cerium Oxide from Bastnasite with Hydrochloric Acid by Two-Step Leaching
Metallurgical and Materials Transactions
; Roasted with sodium carbonate, bastnasite (Ln(Ce)CO^sub 3^F) was converted to calcine containing rare earth oxides (REO), among them cerium, which existed mainly as CeO^sub 2^. The calcine was first leached with diluted hydrochloric acid, which resulted in a sludge with the enriched cerium (IV)
