Miyauchi Lab (Functional Materials Engineering)
Machine-translated · View original
The lab harnesses the unusual properties of nanomaterials to put the energy of heat and light to use.

AboutAbout the lab
Freely controlling the energy of heat and light
The Miyauchi Lab conducts nanotechnology research aimed at new technologies that use solar and thermal energy efficiently.
The lab investigates the properties and functions of nanoscale materials, such as carbon nanotubes, in which quantum mechanical effects appear clearly, and their applications to energy.
Its research spans from the fundamentals of condensed matter physics and materials synthesis, through thermal, mechanical, electronic, and optical engineering, to materials development.
Prof. Miyauchi holds a concurrent appointment at the Institute of Advanced Energy, Kyoto University, and the lab operates at two sites: Kyoto University and the University of Tokyo.
Key terms
- Carbon nanotube

ResearchResearch themes
Aiming for a sustainable energy society, the lab works toward new technologies that use solar and thermal energy with high efficiency. Its research focuses on the properties and functions of nanoscale and quantum materials, including carbon nanotubes, and their energy applications.
*Illustrative imageTurning the Thermal Light of Nanotubes into Solar Energy
The lab applies the phenomenon in which hot carbon nanotubes emit light at specific wavelengths to the control of thermal radiation. It aims to realize devices that reshape the solar spectrum and to extend this work to applications such as solar thermal power generation.
*Illustrative imageAssembling Nanomaterials into New Materials
This research creates materials with excellent optical, thermal, electronic, and mechanical properties, such as carbon nanotube assemblies (films) and composites. Its goals include materials for thermal management and lightweight, extremely strong materials.
*Illustrative imageThermal and Optical Properties of New Quantum Materials
The lab investigates the thermal and optical properties at high temperatures of new nanomaterials such as atomically thin semiconductors. It is also pursuing research that leads to technology for converting infrared radiation, such as that emitted as waste heat from factories and homes, directly into electricity.
