Morikawa Lab
Machine-translated · View original
A lab that precisely measures how heat is transmitted and applies the findings to materials development.
AboutAbout the lab
Accurately measuring how heat travels
The Morikawa Lab studies the fundamental physical properties of materials based on measurements of thermal energy and thermophysical properties.
Temperature wave analysis, which the lab has developed over many years, is used to measure all kinds of materials, not just polymers, and has been adopted as an international standard.
The lab also develops thermal imaging with infrared cameras, as well as new thermal analysis methods combined with other structural analysis techniques.
It also works on applications in materials development, such as heat-dissipating and heat-insulating materials and thermal control at the interfaces of multilayer materials.
Key terms
- Thermal diffusivity
- A quantity that expresses how quickly heat travels through a material
- Temperature wave analysis
- A method that changes temperature periodically like a wave and measures the thermal properties of a material from how the wave propagates
- Infrared camera
- A device that captures the infrared radiation emitted by objects and shows the distribution of surface temperature as an image
ResearchResearch themes
The lab conducts fundamental research on physical properties based on measurements of thermal energy and thermophysical properties. Heat-related problems have become the focus of development competition in cutting-edge fields such as CPUs, power transistors, new types of batteries, and packaging materials for LED lighting.
*Illustrative imageMeasuring heat with temperature waves
Focusing early on AC methods of thermal analysis, the lab has developed temperature wave analysis over many years. It is now used to measure the thermal diffusivity of all kinds of materials, not just polymers, and the results have been adopted as an international standard.
*Illustrative imageSeeing heat with infrared
As one of the next-generation thermal analysis methods, the lab works on imaging in the infrared wavelength range. It develops both radiation-based and spectroscopic imaging instruments, together with analysis algorithms, in connection with materials development.
*Illustrative imageDeveloping new thermal analysis methods
Combining multiple techniques is another direction for next-generation thermal analysis. The lab combines thermal diffusivity measurement using temperature waves with structural analysis such as atomic force microscopy, Raman spectroscopy, and X-ray diffraction, aiming to elucidate the physics of heat conduction.
*Illustrative imageDeveloping heat-dissipating and heat-insulating materials
From the standpoint of saving energy and reducing environmental impact, thermal conductivity has become an essential property in materials development. Key challenges include insulation performance for food preservation and for keeping buildings warm, and heat dissipation inside electronic devices and engine compartments.
