Towards electron transport measurements in chemically modified graphene: The effect of a solvent

Autor: Jacobsen, A., Koehler, F. M., Stark, W. J., Ensslin, K.

Publikováno v: New J. Phys. 12 (2010) 125007

Chemical functionalization of graphene modifies the local electron density of the carbon atoms and hence electron transport. Measuring these changes allows for a closer understanding of the chemical interaction and the influence of functionalization

Advanced piezoresistance of extended metal/insulator core shell nanoparticle assemblies

Autor: Athanassiou, E. K., Krumeich, F., Grass, R. N., Stark, W. J.

Publikováno v: PRL 101, 166804 (2008)

Assembled metal/insulator nanoparticles with a core/shell geometry provide access to materials containing a large number (>106) of tunneling barriers. We demonstrate the production of ceramic coated metal nanoparticles exhibiting an exceptional press

Simultaneous deposition of Au nanoparticles during flame synthesis of TiO2 and SiO2

Autor: Lutz Mädler, Stark, W. J., Pratsinis, S. E.

Publikováno v: Scopus-Elsevier

Nanostructured gold/titania and gold/silica particles with up to 4 wt% Au were made by a single-step process in a spray flame reactor. Gold(III)-chloride hydrate and titania- or silica-based metalorganic precursors were mixed in a liquid fuel solutio

Flame-made Ceria Nanoparticles

Autor: Lutz Mädler, Stark, W. J., Pratsinis, S. E.

Publikováno v: Scopus-Elsevier

Flame spray pyrolysis (FSP) has been used to synthesize high-surface-area ceria from cerium acetate in acetic acid solution. With the addition of an iso-octane/2-butanol mixture to that solution, homogeneous CeO2 nanoparticles were obtained. The spec
