> What is SuperSTEM ?
> The SuperSTEM project involves the development of two aberration-corrected
> STEM instruments in a five-year, Ł4.2 million project funded as a result
of
> the NW Science Review. The microscopes have been installed in a specially
> designed and purpose built facility on the Daresbury Laboratory site in
> Cheshire, and ultimately they will be available as a national resource.
> SuperSTEM provides a world-leading atomic imaging and analysis facility
> capable of chemical spectroscopy from single atoms and atomic columns ­
> further details may be found by visiting www.superstem.org.uk. The
SuperSTEM
> project is led by five scientists from four partner universities [Peter
> Goodhew, Mick Brown, Alan Craven, Rik Brydson and Gordon Tatlock]. The
> full-time research team comprises a Technical Director [Dr Andrew
Bleloch],
> two research microscopists [Dr Uwe Falke and Dr Meiken Falke], a computer
> specialist [Will Costello] and a technician [Peter Shiels]. This project
is
> part of a set of six studentships recently funded by the Engineering and
> Physical Sciences Research Council and as such is fully funded (fees and
> maintenance) for both UK and EC students. The project will be based at the
> IMR in Leeds but will involve extensive travel to Daresbury Laboratories.
>
> The studentship will examine a limited range of metal oxide nanoparticles
of
> varying mean particle size and size distribution. Systems of current
> interest include:
> (a) bare, carboxylic acid stabilized and charge stabilized Fe3O4
> nanoparticles produced by standard colloidal routes at Leeds.
> (b) g-Al2O3 and -g-Al2O3/ CeO2 catalyst supports produced at Leeds or
> obtained commercially.
>
> Atomic resolution HAADF and EELS measurements using the SuperSTEM I
facility
> will be undertaken. With an aberration corrected probe size of around 0.14
> nm and below it will be possible to resolve the oxygen sub-lattice. A
> combination of Z contrast imaging and EELS measurements at particle
surfaces
> (both direct and aloof beam measurements to maximize surface excitations)
> and within the particle core will give structural and spatially resolved
> chemical/ electronic information. It is intended that results will be
> compared with theoretical calculations, both ab-initio total energy/
> electronic structure calculations as well thermodynamic predictions.
>
> An extension of this project, pertaining directly to the life sciences,
> would involve an investigation of iron oxide nanoparticles in human liver
> biopsies in collaboration with Dr Alice Warley and Dr Jonathan Powell at
> Kingšs College London.
