Toward a truly photostable PbSe quantum dot (QD), we apply the thick-shell or "giant" QD structural motif to this notoriously environmentally sensitive nanocrystal system. Namely, using a sequential application of two shell-growth techniques-partial-

Rates of Electron Self-Exchange Reactions between Oxo-Centered Ruthenium Clusters Are Determined by Orbital Overlap

Autor: Christina J. Hanson, John Goeltz, Clifford P. Kubiak

Publikováno v: Inorganic Chemistry. 48:4763-4767

We report rate constants for electron self-exchange of trinuclear ruthenium clusters of the type [Ru 3 O(OAc) 6 (CO) (L) 2 ] 0/― , where L is 4-cyanopyridine, pyridine, or 4-(dimethylamino)pyridine. Rate constants were determined by 1 H NMR line-br

Publikováno v: International Congress Series. 1300:271-274

We are developing a bioassay technique utilizing superparamagnetic and ferromagnetic microparticles, with the aim of using these in biological labeling. The technique uses two independent pieces of instrumentation; a magnetophoresis instrument and a
