Professor Takahiko Miyazaki's research lab specializes in adsorption science and materials engineering, focusing on the development and application of advanced adsorbents for environmental and energy-related technologies. The lab investigates porous materials such as silica gel and carbon-based adsorbents (CBAs) for efficient water vapor capture, with particular emphasis on dehumidification in greenhouses and low-temperature regeneration processes. Key research directions include adsorption isotherms, thermodynamic modeling (e.g., GAB and Dubinin-Astakhov models), and optimizing adsorbent performance for sustainable climate control systems. The lab aims to enhance energy efficiency and reduce material usage in humidity control through innovative adsorbent design and characterization.

Adsorption of water vapors onto silica-gel and two types of carbon based adsorbents (CBAs) has been experimentally investigated. Adso!ption data has been analyzed for various adsorption models. The Guggenhein, Anderson. De-Boer (GAB) and Dubinin-Astakhov (D-A) models gave the good fit for silica-gel and CBAs respectively with an error of less than 5%. The greenhouse air-<:onditioning is proposed the water sorption application for CBAs. Results showed that the CBAs can dehumidify the greenhouse a
