| Outline of Research at the Start |
本研究では、ナノスケールでの高精度計測技術に基づいて、１本のカーボンナノチューブにおける1～10nmオーダーの空間での熱流体による発電現象及び逆の電気浸透現象を定量的に解明する。異なる発電原理の相乗効果を探索し、現存する温度差発電技術の常識を塗り替える新学理の構築を目指して、ゼーベック効果による固体の熱電変換素子を超える「熱流体発電素子」を創出する。

| Outline of Final Research Achievements |
Throughout this project, we have developed an accurate method for measuring flow in nanochannels with depths ranging from tens to hundreds of nanometers. We have further elucidated the reciprocal relations between capillary filling and surface charge in graphene-coated nanochannels. We have also established efficient methods for filling various liquids into individual carbon nanotubes. These achievements pave the way for a complete understanding of the multi-physical phenomena involving flow, electric and thermal effects in nanoconfined spaces, as well as the creation of an electricity generator utilizing thermofluids.
