Research
Biomass utilization is gaining attention as a key solution to resource and energy challenges. Our laboratory focuses on studying the solid structures, physical properties, and unique behaviors of various polysaccharides, particularly cellulose. By building a fundamental understanding of these structures and properties, we also explore the development of advanced functional materials.
1. Understanding biomass materials
Biomass can be utilized either in its natural state, like wood, or transformed into new materials through processes such as grinding or dissolution. Our research focuses on elucidating the structures of polysaccharides and wood across various states—from solid to dissolved—using techniques such as X-ray diffraction, nuclear magnetic resonance (NMR, MRI), and microscopy. Additionally, we are developing advanced data analysis methods for these instruments, integrating new technologies like image analysis to gain deeper insights into the complex structures of biomass.
