Autor: Friedrich Hensel, J.R. Festag, J. Pebler, Rolf Schäfer, Stefan A. Quaiser, Joachim H. Wendorff, J.A. Becker, Manfred T. Reetz, Wolfgang Helbig

Publikováno v: Surface Review and Letters. :1121-1126

Magnetization curves of stabilized cobalt-cluster dispersions in tetrahydrofuran with a narrow size distribution have been studied by SQUID and Gouy balance measurements. The cobalt colloids are generated by a newly developed electrochemical method w

Investigation of Tetraalkylammonium Bromide Stabilized Palladium/Platinum Bimetallic Clusters Using Extended X-ray Absorption Fine Structure Spectroscopy

Autor: Stefan A. Quaiser, Manfred T. Reetz, Martin Winter, Uwe Kolb

Publikováno v: Chemistry of Materials. 8:1889-1894

Structural investigations using EXAFS spectroscopy and standard analytical methods were performed on electrochemically synthesized tetrabutylammonium bromide stabilized Pd/Pt bimetallic clusters with different Pd/Pt ratios. The results of these inves

Tunneling conduction in Co‐cluster/tetraoctylammonium bromide/poly(phenyl‐p‐phenylenevinylene) nanocomposites

Autor: Friedrich Hensel, Manfred T. Reetz, S. D. Baranovskii, Stefan A. Quaiser, Jörg August Becker, G.‐F. Hohl

Publikováno v: Journal of Applied Physics. 78:7130-7136

A system of nanometer sized cobalt clusters surrounded by dielectric shells has been investigated by electrical dc conductivity measurements. The cobalt clusters have a diameter of 36 A and are surrounded by an approximately 12‐A‐thick layer of t

Electrochemical growth of superparamagnetic cobalt clusters

Autor: Wilhelm Ruland, Manfred T. Reetz, Joachim H. Wendorff, R. Festag, Wolfgang Helbig, J. Pebler, Jörg August Becker, Rolf Schäfer, Stefan A. Quaiser

Publikováno v: The Journal of Chemical Physics. 103:2520-2527

The magnetization of stabilized cobalt colloids in tetrahydrofuran has been studied by a superconducting quantum interference device (SQUID) and magnetic balance measurements in dependence of applied magnetic field and temperature. The colloids are g

ChemInform Abstract: Electrochemical Preparation of Nanostructured Bimetallic Clusters

Autor: Wolfgang Helbig, Manfred T. Reetz, Stefan A. Quaiser

Publikováno v: ChemInform. 27

Recently the authors reported an electrochemical method for the size-selective preparation of tetraalkylammonium salt-stabilized transition-metal clusters in the size range of 1-6 nm. In this procedure, a sacrificial anode such as a palladium or nick
