Dr Martin Saunders

Research Interests & Areas of Expertise:

* Characterisation of the structure, composition and chemistry of materials at the nano or atomic scales by transmission electron microscopy (TEM) including:
* Nanomaterials - nanoparticles, thin films, carbon nanotubes and fullerenes
* Semiconductors - thin films, high-k dielectrics
* Metal alloys - shape memory alloys
* Biological systems - biomineralisation, nanotoxicology

* Application of analysis techniques including electron diffraction, HREM, EELS, EFTEM, EDS, STEM, electron holography.

* Development and application of novel TEM techniques, particularly for the quantitative analysis of TEM data

* Quantitative convergent beam electron diffraction

Current Students:

Mr Karel Hartlieb (PhD): Synthesis and characterisation of nanomaterials formed by Spinning Disc Processing

Ms Wendy Loh (PhD): Nanotoxicology of organic nanoparticles

Mr Clint Johnson (PhD): Nanotoxicology of inorganic nanoparticles

Mr Victor Wong (Undergraduate): Optimising TEM imaging and analysis of biological sections.
