About enviro-sustainable materials science lab.

This laboratory was started as an endowed research course at Institute of Agriculture, Tokyo University of Agriculture and Technology (TUAT) on July 1, 2022. Principal investigator is Tetsuo KONDO Ph. D. who specializes bio-material design. Here, objective of this lab contributes to establish sustainable society to propose noble methods and bio-based materials. We are confident that our today’s research can contribute to tomorrow’s society.

Recruitment: Master&doctor course students + doctrial course for working adults！

Greeting from Prof. Tetsuo KONDO

Material design using water and biological function -Novel functional bio-based material controlled in micro/nano-scales- Challenge: Social implementation for establishement of sustainable society

My previous studies focused on native carbohydrate polymers and fibers including cellulose as the main subject, and chitin and chitosan, β-1,3 glucan, and hyaluronan as well as native protein fibers including collagen, fibroin, actin and myosin. These materials are having hierarchical structure in nano- to micro-scales, which are finely constructed by thermodynamics in water. I have been engaged in these bio-based materials more than 40 years. I was realized that contribution of these materials to society was requested so long time. Therefore, I start this laboratory to apply to social implementation as soon as possible. I hope this laboratory contributes to the sustainable society.

Aqueous counter collision

（ACC） method

We have been proposed ACC-bionanofibers. Now further investigation of applying ACC method.

Amphiphilic ACC-

cellulose nano-fibrils

Fluorescence observation Blue:Hydrophilic site due to -OH reside, Red:Hydrophobic site due to gluco-pyranose units

T. Tsuji et al., Biomacromolecules, 22, 620-628, (2021) T. Kondo KONA Powder and Particle J. 40 109–123 (2023)

ACC-CNF adsorbed onto iPP particle easily!

Because ACC-nanofibrils have hydrophobic site, the phenomena easily happened by mixing. In addition, after molding, the ompact strength 30 % increasing!
