Practical Crystallography with a Transmission Electron Microscope (2025)
Preprint / Working Paper
Weare, B. L., Fung, K. L. Y., Cardillo-Zallo, I., Cull, W. J., Fay, M. W., Argent, S. P., & Brown, P. D. Practical Crystallography with a Transmission Electron Microscope

Three-dimensional electron diffraction (3DED) is a powerful technique providing for crystal structure solutions of sub-micron sized crystals too small for structure determination via X-ray techniques. The entry requirement, however, of a transmission... Read More about Practical Crystallography with a Transmission Electron Microscope.

Uniform, less 10 nm sized, hollow carbon nano-shells (HCNS) have been prepared via a single-step, thermal treatment of alkanethiol stabilised Ag nanoparticles (TS-AgNP). Direct evidence for the formation of spherical HCNS from TS-AgNP is provided by...

The tribological behaviours of TiC-based cermet coatings, prepared by electrical discharge coating (EDC) using a semi-sintered TiC tool electrode, have been investigated. The as-deposited coatings exhibited complex microstructures, comprising TiC gra... Read More about Wear performance of TiC/Fe cermet electrical discharge coatings.

Modelling of single spark interactions during electrical discharge coating (2017)
Journal Article

Observations of orthogonal orientations demonstrate the development of banded contrast features on inclined {-1-1-1}B planes for the [110] projection within micron thick samples, attributed to a compositional fluctuation in the Mn content. The relat... Read More about Structural characterisation of spintronic GaMnAs and GaMnN heterostructures grown by molecular beam epitaxy.
