Carbonisation of biomass-derived chars and the thermal reduction of a graphene oxide sample studied using Raman spectroscopy
(Elsevier, 2013)Chars and carbonised chars were produced from three different oxygen-rich precursors (Pinus radiata wood, Phormium tenax leaf fibres, and sucrose crystals). These non-graphitisable carbons were analysed with Raman spectroscopy ... -
Characterisation of watersoluble polysaccharides produced during prehydrolysis of pinus radiata
(The University of Waikato, 2010)An aqueous prehydrolysate (or prehydrolysis liquor) was produced during a mild hot-water prehydrolysis (90 minute ramp to 175 C) of commercial radiata pine wood chips. Oligosaccharide and polysaccharide material was separated ... -
Improving the alignment of dynamic sheet-formed mats by changing nozzle geometry and their reinforcement of polypropylene matrix composites
(MDPI AG, 2021)The main objective of this study was to improve the orientation of fibres within the mats produced using dynamic sheet forming (DSF). DSF is used to make fibre mats by forcing a fibre suspension through a nozzle onto a ... -
Moisture sensitivity and compressive performance of 3D-printed cellulose-biopolyester foam lattices
(Elsevier, 2021)Biobased, foam-like polyester composite materials were 3D-printed from a thermoset paste formulation. This paste formulation was composed of sebacic acid, glycerol, citric acid, and cellulose nanocrystals in water and ... -
Studying carbonisation with raman spectroscopy
(2013)Raman spectroscopy can provide fast and non-destructive analysis of carbonaceous materials. As it is able to detect nanometre-sized structural features, Raman spectroscopy is widely used in the study of carbon nanotubes, ...

3D printing of bio-inspired, multi-material structures to enhance stiffness and toughness
(The University of Waikato, 2021)In nature, many biological, multi-materials have complex microstructures and excellent mechanical properties. One shellfish material called nacre has received much attention due to its unique interlocking structure of ...
