Dr. Seong H. Kim obtained his Ph.D. degree from Northwestern University and completed post-doctoral research at University of California in Berkeley. He as a faculty joined in the department of Chemical Engineering in The Pennsylvania State University in 2001. Dr. Seong H. Kim as adjunct professor works in Southwest Jiaotong University in Chengdu. His lab is investigating fundamental molecular mechanisms of chemical and mechanical processes occurring at solid/gas, solid/liquid, and solid/solid interfaces as well as structure-property relationships of biomaterials. One of the research in his lab focuses on cellulose structure and formation. They are using sum frequency generation (SFG) vibrational spectroscopy. This principle can be used to distinguish the three-dimensional organization of crystalline cellulose microfibrils interspersed in amorphous polymer matrices such as plant cell walls. This talk will address how SFG can be used to reveal the cellulose crystal structure and mesoscale cellulose microfibril packing in primary cell walls and secondary cell walls in their native states. The relative research results were published in The Plant Cell, PNAS, Plant Physiology, Cellulose, Biomacromolecules, ect.
