Daiguji-Hsu Lab
Machine-translated · View original
The lab studies how to make machines that heat and cool more energy-efficient, starting from phenomena at the nanoscale.
AboutAbout the lab
Bringing nanoscale innovation to machines.
The Daiguji-Hsu Lab studies energy and transport phenomena, particularly machines that heat and cool.
The lab approaches heat and mass transport from first principles, including phase change, chemical reactions, and movement in the nano- and microscale world, with the aim of improving the performance and efficiency of machines.
The lab explores ways to apply nanospace materials, porous metals, superhydrophobic materials, and similar materials to real machines.
Energy systems such as air-conditioning systems, turbines, and batteries are also subjects of its research.
Key terms
- Phase change
- A phenomenon in which a substance changes its state among solid, liquid, and gas, as when water turns into ice or water vapor
- Nanopore
- An extremely small hole, measured in billionths of a meter. Water and molecules inside it move differently from how they usually do
- Superhydrophobicity
- The property of strongly repelling water. Water droplets do not wet the surface and instead form round beads

Aiming for energy-saving technologies that improve the efficiency of energy conversion and transport, the lab studies physical phenomena such as phase change, chemical reactions, and heat and mass transport at the nano- and microscale. Its goal is to apply nanoscale innovation to macroscale machines.
*Illustrative imageMass transport in nanospaces
The lab fabricates structures such as nanopores and nanochannels, as well as devices that incorporate them, and investigates the behavior of molecules, ions, and liquids moving inside them. It also carries out molecular simulations.
*Illustrative imageMaterials with surface or hollow structures
The lab fabricates materials with microscale surface structures or hollow structures, such as superhydrophobic surfaces, perforated plates, foams, and hollow capsules, examines their properties, and explores how they can be used.
*Illustrative imageMaterials for energy systems
The lab applies functional materials with nano- and microscale structures to energy systems. Targeting air-conditioning systems, turbines, batteries, and more, it conducts joint research with materials researchers and engineers.
