image: Pyrolysis set up: A quartz boat filled with catalyst precursor and a red glass rod (with magnet in one end) inside of a pyrolysis tube placed in a split-hinge tube furnace (left). The quartz boat is slid into the furnace heating zone by means of an external magnet. This image relates to an article that appeared in the April 3, 2009, issue of Science, published by AAAS. The study, by Dr. Michel Lefèvre of INRS, Energie, Materiaux et. Telecommunication in Varennes, Quebec, Canada, and colleagues was titled, "Iron-Based Catalysts with Improved Oxygen Reduction Activity in Polymer Electrolyte Fuel Cells." view more
