MUS Materials Science Symposium

Friday, October 4 - 

Dr. David Tyler (Department of Chemistry and Biochemistry, University of Oregon) will present "Homing Pigeons, Degradable Plastics, and Solvent Effects; How Caged Radical Pairs Impact Everyday Chemistry."  Byker Auditorium at 3:10 pm.  Prof. Mike Mock host.

Abstract:

How do homing pigeons navigate?  How do we design plastics so they degrade after they are used?  Why are solar energy conversion systems with donor and acceptor complexes so inefficient?  Why do bonds break more readily if they are under mechanical stress?  It turns out that radical cage effects are important in understanding the answers to these and numerous other practical questions involving chemical reactivity.  In this seminar, I will introduce the concept of caged radical pairs, and then I will show why caged radical pairs are key intermediates in the systems mentioned above and in radical reactions, in general.

Friday, October 18

Ms. Amanda Fuchs will defend her PhD in Biochemistry beginning with a seminar titled "Quantitative 1H NMR Analyses of Immunometabolic Modulation in Human Macrophages.” Amanda works in the lab of Prof. Valérie Copié.  3:10 pm in the Byker Auditorium.

Friday, October 25 

Dr. May Nyman from Oregon State University will present "Building Materials from Molecular Clusters" in the Byker Auditorium at 3:10 pm.  Prof. Nick Stadie will host.

Abstract:

Metal-oxo clusters are modular building blocks for materials via hydrolysis reactions and coordination chemistry. Landmark discoveries in cluster-based materials include zeolites and MOFs. Understanding and controlling solution phase reaction pathways from monomers to clusters to materials (and vice versa) will lead to new discoveries from across the periodic table, and most aspirational, the next new class of cluster-based materials.

I will present an overview of our studies of metal-oxo clusters and their importance in functional materials and understanding reaction pathways, beginning with an introduction to small-angle X-ray scattering as a primary tool in studying cluster systems. Time permitting, presented cluster systems will include; 1) The iron Keggin ion and its relevance to natural systems; 2) Diversifying Zr/Hf oxocluster chemistry with peroxide (and use in microelectronics); 3) Behavior of Nb-POMs around neutral pH; and 4) heterometallic U(IV) clusters and materials.

"The Strong Weak-Interaction in Protein"

ABSTRACT:

Noncovalent weak interactions play important roles in biological systems [1]. In particular, such interactions in the second-coordination shell of metal ions in proteins modulate the structure and reactivity of the metal ion site in functionally significant ways.

Recently, we have demonstrated the perturbation of weak non-covalent interaction on the structure and properties of copper site in a blue copper protein, pseudoazurin (PAz) [2]. PAz is well known to work as an electron transfer protein to NO2- reductase and N2O reductase in denitrifying bacteria [3]. The weak interaction at Met16 with a copper coordinated histidine (His81) imidazole ring in the second coordination sphere provides significant effect not only for the PAz properties and local structure but also the whole protein stability [4].

In this lecture, I also would like to introduce the utilization of modern quantum beams involving Synchrotron X-ray, Neutron Beam, and Muon in bioinorganic chemistry.
