Iridium nanoparticles resist deactivation in biofuel production

Steam reforming turns methane from biomass into a mixture that can be further converted into transportation fuels. By combining experimental and theoretical approaches, researchers at the Pacific Northwest National Laboratory (PNNL) Institute for Integrated Catalysis determined key properties of potentially...

Rätsel des platinarmen Nanokatalysators geklärt

Neuartige Nanopartikel-Katalysatoren könnten die Kosten für Brennstoffzellen dramatisch reduzieren. Ein von Berliner und Jülicher Forschern entwickelter Katalysator kommt mit einem Zehntel der üblichen Platinmenge aus. Doch wie die oktaedrische Form der Partikel und die besondere Verteilung der Elemente zustande kommen, war bisher unklar. Mithilfe...

Van der Waals epitaxy and photoresponse of hexagonal tellurium nanoplates on flexible mica sheets

Van der Waals epitaxy (vdWE) has recently been identified as a facile synthesis technique in the growth of ultrathin two dimensional (2D) layered materials and their vertical heterostructures. Unlike conventional heteroepitaxy, vdWE utilizes substrates whose surface is chemically inert because of the absence of surface dangling bonds such as fluorophlogopite...
