Fabrication of intrinsic Fabry–Pérot sensors through proton irradiation Open
We report on a new technique to fabricate intrinsic fiber Fabry–Pérot interferometric sensors by exposing partially shielded end-faces of cleaved optical fibers to 27 MeV proton irradiation. The dimension of the shield that was placed in f…

Theoretical framework and experimental validation for monitoring the glass transition temperature of thermosets using a low-cost Fresnel reflection sensor Open
The first part of this paper reports on the theoretical basis for using an optical fibre-based Fresnel reflection sensor for monitoring the cross-linking reactions, and subsequently, the evolution of the glass transition temperature. The F…

The effect of end-tabbing methods on the tensile properties of electro-spun highly aligned PAN nano-fibres Open
A novel electro-spinning method was used to produce highly aligned polyacrylonitrile (PAN) nano-fibre arrays. The tensile properties of the aligned fibres were investigated where three different adhesives were used in the end-tabs, namely,…

LiverUSRecon: Automatic 3D Reconstruction and Volumetry of the Liver with a Few Partial Ultrasound Scans Open
3D reconstruction of the liver for volumetry is important for qualitative analysis and disease diagnosis. Liver volumetry using ultrasound (US) scans, although advantageous due to less acquisition time and safety, is challenging due to the…

Xenon plasma-FIB micromachined cavity-based fiber sensors for refractive index, temperature and chemical sensing Open
Xenon plasma-FIB micromachining has been used for relatively rapid (10-20 minutes) production of intrinsic Fabry-Perot cavities in fused silica single and multimode fibers without any post-processing. Infiltration of organic solvents into …

Vertically-aligned short E-glass fibre core sandwich composite: Production and evaluation Open
This paper reports on the production and evaluation of a new class of “Z-axis” composite sandwich panel where the core consists of a dense array of vertically-aligned, 3 mm long E-glass fibre composite “beams”. The E-glass fibre bundles we…

Improved Procedure for Electro-Spinning and Carbonisation of Neat Solvent-Fractionated Softwood Kraft Lignin Open
In general, the electro-spinning of lignin requires it to be functionalised and/or blended with synthetic or natural polymers. This paper reports on the use of solvent fractionated lignin-lignin blend to electro-spin BioChoice® softwood Kr…
