Title: Protein Mechanics: How Collagen and Tubulin Hold Life Together
When considering molecular biology, topics involving the mechanics of materials don’t typically come to mind. However, in the dawning age of nanomaterials, it has become clear that the language of material mechanics quickly becomes relevant. Associate Professor Layton will review some of the work he has done in protein evolution, collagen mechanics, tubulin mechanics, and diabetic neuropathy. Attendees will have the opportunity to discover how many of the same material mechanics principles that apply at the human scale also have relevance at the molecular scale.

Title: Lignin Copolymers and Grafting Cellulose onto Bioplastics
This seminar will cover two of projects on biobased materials.
- A series of lignin-copolymers were prepared using industrial lignins and hyperbranched prepolymers (HBP) via melt condensation. To obtain different HBP structures (A2B3, B3-A2-CB31) the prepolymers were synthesized using various difunctional diacids (A2, e.g. adipic acid), trifunctional alcohols (B3, e.g. glycerol and triethanolamine), tertrafunctional alcohol/amine (CB31, tris(hydroxymethyl)-aminomethane) building blocks. These lignin copolymers were elastomeric and shown to have thermally stimulated shape memory effects (SME). Different branching and core structures of the HBP (soft segment) were shown to influence the properties of the lignin-copolymers. The results demonstrated that properties of lignin-copolymers could be tuned through lignin type, lignin content, prepolymer structure, and monomer variations. This study demonstrated that lignin, a renewable byproduct, can be promisingly valorized to apply as a netpoint segment in biobased polymer systems with SME behavior.
- Green biocomposites from the bacterial bioplastic, poly-3-hydroxybutyrate (PHB), and cellulose fibers was prepared. Grafting of PHB onto cellulose was carried out by reactive extrusion using dicumyl peroxide free radical initiation. The chemical, mechanical and thermal properties were evaluated. The mechanical properties of the biocomposites were improved by cross-linking due to better stress transfer between the two interphases as compared to the blend control composite without adding peroxide. This inline process offers an effective approach to improve biocomposite materials by reactive extrusion.
