  Soy polyurethanes Scientists at Battelle (Columbus, Ohio; www.battelle.org) have developed a water-based polyurethane (PU) that uses soy oil instead of petroleum to produce the polyol precursor. Whereas standard water-based PUs require adding N-methyl-2-pyrrolidone (NMP) tolower viscosity, Battelle’s process eliminates the need for NMP, thereby reducing costs, handling, reporting regulations, vapors and pollution, says Battelle. The new PU has less odor (no pun intended) than petroleum-based PUs and can be used in applications such as paints, inks, top coatings, seal coatings, as well as adhesives and the "peel-and-go" market. Battelle has filed a patent, and will seek licensing partners to scaleup the product to mass manufacturing. New MOFs Researchers from the KIT Institute of Functional Interfaces (IFG; Karlsruhe, Germany; www.kit.edu), with collaboration from other institutions in Bremen, Mainz, Bielefeld and Thuwal (Saudi Arabia), have developed a new method to produce metal-organic frameworks (MOFs) with pore sizes never reached before. MOFs are highly ordered molecular systems with metal atoms at nodes and organic components as rods. The pores in these frameworks are freely accessible. MOF powders are…
