Prof. Hiroshi Uyama of Osaka University as a foreign expert was invited to MoSE/AISMST to give lectures for our graduate and undergraduate students on 14th November. The lectures were conducted online, and contained two parts: (1) the basic knowledge and advanced development of bioplastics; (2) the structure and properties of cellulose.

In the first lecture, prof. Hiroshi Uyama introduced the concept, typical examples, and commercial products, and imparted the basic knowledge and the most advanced development of bioplastics to our students. Bioplastics consist of biodegradable plastics and biomass plastics. Biodegradable plastics are decomposed by the action of living organisms into water and carbon dioxide. Use of bioresources as starting substrate of polymeric materials reduces greenhouse warming and contributes to global sustainability without depletion of scarce fossil resources.

Cellulose is the most abundant organic compound on earth and has a linear structure of D-glucose repeating unit. It is one of the three major structural components of the primary cell walls of green plants, along with hemi-cellulose and lignin. In the second lecture, prof. Hiroshi Uyama explained fundamental structure and property of cellulose, important industrial products of modified cellulose, and cellulose nanofibers which are recently expected as new functional materials.

The current research interests of prof. Hiroshi Uyama focus on renewable polymer materials, functional biomaterials, and porous materials. He has already published more than 410 papers and 150 patents. The professional knowledge and important practical applications make the lectures attractive and valuable.
