Determination of spin injection and transport in a ferromagnet/organic semiconductor heterojunction by two-photon photoemission
Mirko Cinchetti, Kathrin Heimer, Jan-Peter Wüstenberg, Oleksiy Andreyev, Michael Bauer, Stefan Lach, Christiane Ziegler, Yongli Gao & Martin Aeschlimann
Published online: 23 November 2008; | doi:10.1038/nmat2334
One of the challenges posed by spin manipulation in organic semiconductors is the difficulty of measuring the spin injection from a ferromagnetic contact and the subsequent spin diffusion length. This is now elegantly achieved by a two-photon photoemission experiment.

Thermally stable Pt/mesoporous silica core–shell nanocatalysts for high-temperature reactions

Colloidal synthesis can help to precisely control the shape and composition of catalytic metal nanoparticles, but it has so far proved difficult to use these particles in high-temperature reactions. Core–shell structures capable of isolating Pt-mesoporous silica nanoparticles have now been shown to be catalytically active for ethylene hydrogenation and CO oxidation at high temperature.

Until print versions of AOP papers are published, they should be cited in the style "Author(s) Nature Materials advance online publication, day month year (doi:10.1038/nmatXXXXX)". Once the print version (identical to the AOP) is published, it should be cited as follows: "Author(s) Nature Materials volume, page (year); advance online publication, (doi:10.1038/nmatXXXXX)".
