- Profile
-
I joined Sheffield University in Oct 2002. My graduation at Stuttgart University in Germany was followed by moving for PhD and postdoctoral years to the Max-Planck-Institut for Metals Research in Stuttgart. In 1998 I was awarded an EPSRC Advanced Fellowship, held first at Oxford University, and then at Sheffield University until 2003. Since then I am a member of Academic Staff, now holding a Readership.
- Research interests
-
Nanoscale materials such as nanoparticles or materials with nanoscale pores are expected to make an increasingly important contribution to future-proofing economy & society, spanning application areas in energy, catalytic, optical and biomedical materials sectors. To evaluate the potential of such nano-objects, they need to be precision-characterized, with electron microscopy playing a central role at a resolution level of 0.1nm and magnifications up to 1 million times. Atomic positions and elemental distributions can not only be measured, but also modified and engineered, such as e.g. to change surface activities or physical/chemical properties
Key research interests:
- Advancement of methods of 3D nanocharacterisation, such as novel electron tomography including EELS and EDX.
- Patterning and irradiation-modification of materials on the nanoscale, such as water-irradiation induced corrosion of oxide nanomaterials, nanoprecipitate formation in glasses, and nano-porous masks for ion implantation.
- Atomic resolution characterisation of nanoparticles and surfaces, such as surface atom dynamics, oxidation state distribution of bi-valent cations, and porosity developments in oxide nanoparticles and nanorods.
Key projects (since 2008):
- RCUK Basic Technology Project and Translation Award on “Nanorobotics” (Multi-dimensional imaging & manipulation on the nanoscale): www.nanomanipulation.org; www.nanoLAB.org.uk.
- EU-FP7 project IMCOSS (Collaboration with Sheffield-Dentistry)
- TSB project Nano4Med (Collaboration with Sheffield-Dentistry, Nottingham, and S&N).
- P.I, EPSRC project on nanostructure fabrication by ion implantation (collaboration with U Surrey)
- P.I.,EPSRC project on ceria nanoparticle architectures (collaboration with U Cranfield and U Bath)
