Valorization of the peel and husk of guaraná (Paullinia cupana): oil extraction, chemical composition, cytotoxicity, and antitumor potential

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Guaraná (Paullinia cupana) is a fruit native to the Amazon region. Due to its widespread use, primarily in beverages, its production has grown over the years. The seed is the only commercially valuable part of the fruit so the guaraná production chain generates byproducts, including peel, husk, and spent seed.

Global modeling of secondary organic aerosol formation from aromatic hydrocarbons: high- vs low-yield pathways [PDF]

, 2007
Formation of SOA from the aromatic species toluene, xylene, and, for the first time, benzene, is added to a global chemical transport model. A simple mechanism is presented that accounts for competition between low and high-yield pathways of SOA ...
