Advancements and improvements to etherification and olefination reactionsSynopsis:
Etherification and olefination reactions play an important role in synthetic organic chemistry on a daily basis. As organic chemists we apply these methods to tackle synthetic targets of ever increasing complexity. As a graduate student in the Dudley lab at Florida State University since June of 2006, I have had the opportunity to work on 2 different projects that have dealt with advancing and improving on the methodology of etherification and olefination reactions. The more current of the two projects, recently published in the Beilstein Journal of Organic Chemistry (Lopez, S.S.; Dudley, G.B.; Beilstein J. Org. Chem. 2008, 4, No. 44. doi:10.3762/bjoc.4.44), describes an efficient and convenient protocol for the in situ formation of benzyl ethers and esters using 2-benzyloxyprydine. The latter portion of the talk focuses on the advancements and improvements we have made to the Lewis acid catalyzed Meyer-Schuster rearrangement (Engel, D.A.; Lopez, S.S.; Dudley, G.B. Tetrahedron. 2008, 64, 6988 invited contribution/ Lopez, S.S; Engel, D.A.; Dudley, G.B. Synlett., 2007, 64, 949) which we have efficiently used to olefinate hindered ketones as well as aldehydes.

Polyelectrolyte Multilayers Controlling Protein Adsorption and Cellular Adhesion and MotilitySynopsis:
A7r5 smooth muscle cells cultured on different polyelectrolyte multilayer (PEMU) thin films behaved differently. Cells Adhered and spread well on nafion terminated PEMUs, they attached less and migrated more on poly(allylamine hydrochloride) (PAH) terminated films and they were repelled by all surfaces terminated with a copolymer of acrylic acid and 3-[2-(acrylamido)-Et dimethylammonio] propane sulfonate (PAA-co-PAEDAPS). Fibronectin bound best to PAH and nafion terminated PEMUs but bound poorly to PEMUs terminated with PAA-co-PAEDAPS. Both cells and FN attached onto nafion much better than PAA-co-PAEDAPS on a micropatterned surface.		Chemistry / BiochemistryGraduate - ages 21 - 25Moussallem, Maroun D.Feb 01, 20084Feedback

Science in the 21st Century: Single Molecule MagnetsSynopsis:
Single molecule magnets (SMMs) are compounds that possess very high-spin ground states and, in principle, should exhibit magnetic multi-stability at the molecular dimensions. The size of SMMs is on the nanometer scale, the so-called mesoscale. Hence they exhibit many novel properties, including the quantum tunneling of their magnetization (QTM), i.e. quantum behavior of a bulk property, whose underlying mechanism is still not fully understood. They also hold the potential for becoming elements of magnetic memory devices of molecular dimensions. During the past decades, our group has investigated several SMMs using the unique facilities for NMR, EPR and transport measurements at the National High Magnetic Field lab in Tallahassee. This talk provides a summary of our investigations and a discussion of some future challenges in this field.

Systems Chemistry: How can reactions shape the macroscopic world?Synopsis:
Abstract: 21st century chemistry is slowly expanding its concepts into the realm of supermolecular phenomena. However, few tools exist for explaining, creating and controlling complex macroscopic structures and dynamics. In this talk, I discuss our vision to explore chemical systems that create such complexity via emergent phenomena in non-equilibrium conditions. The feasibility as well as the intellectual and technological merits of this research will be demonstrated for two specific examples: hierarchically structured silica/ZnO tubes and autocatalytic reaction-fronts in three-dimensional media.
