Research Contents
Materials on Earth continuously change their forms and circulate through the Earth system. Our laboratory studies these processes from the perspective of high-temperature materials science, focusing on crystal growth and thermophysical properties of molten materials.
We investigate non-equilibrium phenomena in molten materials, including phase separation, crystal growth, and metastable processes, using containerless techniques and advanced measurement methods. Through these studies, we aim to reveal fundamental principles governing the behavior of materials under extreme conditions and their roles in Earth and planetary processes.
We welcome researchers and students who share our interest in this field.
Containerless measurements of thermophysical properties
We measure surface tension, viscosity, and density of high-temperature melts using aerodynamic levitation and microgravity experiments.
Emissivity-independent temperature measurement
We develop novel temperature measurement methods, including a two-wavelength reflectivity ratio technique that enables emissivity-free thermometry.
In-situ observation of crystallization processes
High-speed imaging and spectroscopy are used to observe nucleation and crystal growth from undercooled liquids.
Latent heat thermal energy storage materials
We develop high-temperature thermal energy storage materials based on miscibility gap alloys.
Metastable materials via undercooling
Undercooling enables the formation of metastable phases and unique microstructures for novel functional materials.
Crystal growth in natural environments
We study mineral formation related to biological activity and weathering processes to understand material cycles in Earth systems.
