New insights into the mechanical properties of Acanthamoeba castellanii cysts as revealed by phonon microscopy (2019)
Journal Article

The single cell eukaryotic protozoan Acanthamoeba castellanii exhibits a remarkable ability to switch from a vegetative trophozoite stage to a cystic form, in response to stressors. This phenotypic switch involves changes in gene expression and synth...

Imaging material texture of as-deposited selective laser melted parts using spatially resolved acoustic spectroscopy (2018)
Journal Article

Additive manufacturing (AM) is a production technology where material is accumulated to create a structure, often through added shaped layers. The major advantage of additive manufacturing is in creating unique and complex parts for use in areas wher...

Size characterisation method and detection enhancement of plasmonic nanoparticles in a pump–probe system (2017)
Journal Article

The optical resonance of metal nanoparticles can be used to enhance the generation and detection of their main vibrational mode. In this work, we show that this method allows the accurate characterisation of the particle’s size because the vibrationa...

Orientation imaging of macro-sized polysilicon grains on wafers using spatially resolved acoustic spectroscopy (2017)
Journal Article

Due to its economical production process polysilicon, or multicrystalline silicon, is widely used to produce solar cell wafers. However, the conversion efficiencies are often lower than equivalent monocrystalline or thin film cells, with the structur...
