Möbus, Günter - University of Sheffield - Department of Materials Science and Engineering

个人简介

Core research develops from the advancement of methods of Characterization, Patterning and Irradiation of Materials on the Nanoscale (Nanometrology & Nanomanipulation). These methods are applied in collaboration with research groups spanning a wide range of research fields in optical, energy, catalytical and biomedical materials sectors. Particular materials examinations include oxide nanoparticles, nanoscale hydroxyapatite, metallic nanostructures with special plasmonic properties, porous alumina and related nanocomposites, piezo-actuation materials, metallic multi-layers, and multi-component oxide glasses, including those for radionuclide immobilisation. Recent priority research topics include: Developments in Nano-Tomography for 3D reconstruction of nanoparticles, nanophases and for 3D chemical mapping of composites. Atomistic structure of nanoparticles, their surface structures and structural dynamics related to catalytic activity, as well as particle-coalescence, using quantitative high- resolution electron microscopy (HREM) and in-situ TEM. Study of structure and chemistry of glasses and ceramics, including radiation induced fluidity, local determination of coordination and oxidation states of cations, coordination of borate units, and precipitation in oxide glasses (e.g. alkali-borosilicates, zinc-borosilicate). Electron and ion beam interactions with materials, including irradiation for patterning of surfaces for nanotechnology applications. New method of porous-alumina-masked ion implantation into substrates for optical and magnetic nanodot patterning

研究领域

Günter Möbus joined the Department in Oct 2002. He graduated at Stuttgart University in Germany before moving for his PhD and postdoctoral years to the Max-Planck-Institut for Metals Research in Stuttgart. In 1998 he was awarded an EPSRC Advanced Fellowship, held first at Oxford University, and then at Sheffield University until 2003.
