Outline of Annual Research Achievements |
The teslacoil has been constructed. The construction of the TEP system was carried out with engineers at the NIMS and internship student from Germany. We followed the original circuit diagram and the detailed construction description provided by Cherukuri. Single nanotube alignment has been proven. The starting materials for supramolecular hydrogels have been synthesised. The supramolecular hydrogel hybrid was synthesised without the teslaphoresis field. Furthermore, we have employed aligned carbon nanotubes and porphyrin as receptor materials for nano mechanical sensor for gases. The alignment showed stronger sensitivity.

Current Status of Research Progress |
Current Status of Research Progress
1: Research has progressed more than it was originally planned.
Reason
The project was carried out as proposed. We have constructed the teslacoil. The single walled nanotubes were functionalized with host cyclodextrin and the gelatine was funtionalized with guest adamantane. The supramolecular hydrogel hybrid was prepared without the teslaphoresis field. Furthermore we employed the teslacoil during the deposition of single walled nanotubes and porphyrin on mechanical sensors to investigate the possible effect of nano alignment on the sensitivity. The obtained results showed that the alignment strongly effect the sensitivity to gasses. We will continue to investigate this effect as side project of our proposal.

Strategy for Future Research Activity |
Synthesis of supramolecular hydrogel hybrid in the teslaphoresis field. Material synthesis by HOST-GUEST + π-π stacking interaction under TEP field: 1) Applying teslaphoresis Field → Alignment of CNTs crosslinkers 2) Addition of biopolymer → host-guest hydrogelation or ring-slide hydrogelation or Addition of porphyrin + biopolymer → π-π stacking + hydrogelation These approaches fix the CNTs alignment and provide the well-controlled microstructure of material matrix and introduce self-healing properties. Mechanical study of the hydrogel hybrid. Integration of the teslacoil into the construction of receptor materials for mechanical sensors.Furthermore we have discovered additional properties of aligned materials for sensor applications. Therefore we integrate the teslacoil into the nano mechanical sensor for gas sensing.
