- Development of new integrated Fe3O4NP@tiopronin-PDMS polymers. Further experiments on magneto acoustics – continued optimisation required.
- Dip coat hydrophone (parylene) with optimised Fe3O4NP@tiopronin-PDMS coating. Test response.
- Hydrophone experiment led to investigation of achieving PDMS domes on 125 um and 200 um fibres. Range of PDMS:xylene concentrations explored to optimise dome heights. Characterisation using SEM and stereo microscopy. Further experimentation planned.
- Dip coat 300 um fibres in MWCNT-gel and PDMS for probe. Exploration into polishing cleaved fibre to promote adherence of PDMS (in progress).
- Dip coat fibre bundle into MWCNT-gel and PDMS
- Dip coat lense into MWCNT-gel and PDMS
- Coat needles and catheters with MWCNT-xylene and PDMS – photoacoustics
- Raman training
- Continuation of extensive investigation into range of carbon compounds – Recap: Oleylamine functionalised-pyrene ligand was used to functionalise a range of carbon compounds including: SWNTs (6,5), SWNTs (7,6), DWNTs, MWNTs, carbon black, carbon nanofibres, reduced graphene oxide, nanodiamond, mesoporous carbon. Both un-functionalised and functionalised compounds characterized using Raman spectroscopy. Next step – dip coating onto specially designed Perspex keys for a rigorous comparison of compounds used.
- Competition – research ‘crowd-sourcing’ for ultrasound generating coatings. A range of entries submitted, post-coated with PDMS. Optical and ultrasound characterisation to be achieved.
- Sulphur polymer characterisation; Raman, SEM
- TGA characterisation of untreated MWCNTs, MWCNT-xylene and MWCNT-gel coatings
- Electrospinning of graphene/PEO polymer
