ENCOMM seminar – Joel Miller (University of Utah) Organic-based Magnets: New Chemistry, New Physics and New Materials for This Millennium
Organic-based materials exhibiting the technologically important property of bulk magnetism have been pioneered in our laboratory and studied in collaboration with many research groups worldwide. These magnets are prepared via conventional organic synthetic chemistry methodologies, but unlike classical inorganic-based magnets do not require high-temperature metallurgical processing. Furthermore, these magnets are frequently soluble in conventional organic solvents and have saturation magnetizations more than twice that of iron metal on a mole basis, as well as in some cases coercive fields exceeding that of all commercial magnets (e.g., Co5Sm). Also several magnets with critical temperatures (Tc) exceeding room temperature have been prepared. In addition to an overview of magnetic behavior, numerous examples of structurally characterized magnets made from molecules will be presented. Four examples magnetically order above room temperature and as high at 127 oC. These will include [MIII(C5Me5)2][A], [MnIII(porphyrin)][A] (A = cyanocarbon etc. electron acceptors) as well as M[TCNE]x (TCNE = tetracyanoethylene), which for M = V is a room temperature magnet that can be fabricated as a thin film magnet via Chemical Vapor Deposition (CVD) techniques. A newer class of magnets of [Ru2(O2CR)4]3[M(CN)6] (M = Cr, Fe; R = Me, t-Bu) composition will also discussed. For R = Me an interpenetrating, cubic (3-D) lattice forms and the magnet exhibits anomalous hysteresis, saturation magnetization, out-of-phase, c“(T), AC susceptibility, and zero field cooled-field cooled temperature-dependent magnetization data. This is in contrast to R = t-Bu, which forms a layered (2-D) lattice. Additionally, new magnets possessing the nominal Prussian blue composition, M'[M(CN)6]x and (Cation)yM'[M(CN)6], but not their structure, will be described. This forms a series of cation-adaptive structures with [NEt4]2Mn3(CN)8, [NEt4]Mn3(CN)7, [NMeEt3]2Mn5(CN)12 and [NMe4]3Mn5(CN)13 stoichiometries that order as antiferromagnets or ferrimagnets. Finally, Li[TCNE] magnetically orders as a weak ferromagnet (= canted antiferromagnet) below 21.0 K. The structure, determined ab initio from synchrotron powder X-ray diffraction data, consists of a planar µ4-[TCNE]•- bound to four tetrahedral Li+ ions with two interpenetrating diamondoid sublattices, with closest inter-lattice separations of 3.43 and 3.48 Å. At 5 K this magnetic state is characterized by a coercivity of ~30 Oe, 10 emuOe/mol remnant magnetization, and a canting angle of 0.5o. The structure, DC magnetization at ambient and applied pressure, as well as the AC susceptibility at ambient pressure in addition to the computational analysis of the magnetic couplings will be presented. New physics observed from examples of organic-based magnet will be discussed.
This workshop will provide an opportunity for academic and industrial researchers to learn more about NMR and how our new state-of-the-art CCIC NMR facility can directly enhance their research. Both theoretical and hands-on, practical applications will be explored in the areas of basic NMR applications, metabolomics, protein structure and dynamics, polymers, imaging and solids.

James F. Patterson Land-Grant University Lecture
The James F. Patterson Land-Grant University Lecture honors former Board of Trustees member Jim Patterson and the cause to which he is most committed, a vibrant University fulfilling its land-grant mission in an ever-changing world. The lecture brings to campus annually a prominent figure to speak to the range of challenges facing land-grant institutions in the 21st century and beyond. The lecture challenges the university and community audience to continue to use their knowledge and resources and work together to solve world issues.Mr. Patterson served on the University’s Board of Trustees from 1994 – 2003 and served as Chair of the Board 2002-03.

Chancellor Bernadette Gray-Little, University of Kansas
May 3, 2017
Chancellor Bernadette Gray-Little has bold aspirations for the University of Kansas. Since arriving at KU in 2009, Gray-Little has focused on advancing KU’s mission of lifting students and society by educating leaders, building healthy communities, and making discoveries that change the world. In fall 2013, Gray-Little was named to the Board of Directors of the Association of Public and Land-Grant Universities and served as chair for 2015-16. She is an invited member of the Council of Foreign Relations. Prior to becoming KU’s 17th Chancellor, Gray-Little held several leadership positions at the University of North Carolina-Chapel Hill, including executive vice chancellor and provost. She received her B.A. from Marywood College (Scranton, PA) and an M.S. and Ph.D. in psychology from St. Louis University. As part of a Fulbright Foundation fellowship, she conducted postdoctoral research in cross-cultural psychology in Denmark. She has also been a Social Science Research Council Fellow and a recipient of a Ford Foundation Senior Scholar Fellowship through the National Research Council.

Leo Paquette Leagacy Symposium
Leo A. Paquette was born in Worcester, Massachusetts. He received his B.S. degree from Holy Cross College in 1956 and his Ph.D. in Organic Chemistry from MIT in 1959. After serving as a Research Associate at the Upjohn Company from 1959 to 1963, he joined the faculty of The Ohio State University. He was promoted to full professor in 1969, held the Kimberly Professorship from 1981-1987 and was named Distinguished University Professor in 1987.
A member of the National Academy of Sciences since 1984, Dr. Paquette has been a Visiting Professor at institutions across the United States and Europe. He has served in an advisory capacity for advisory committees of the National Institutes of Health and the National Science Foundation, and has been a member of the editorial boards of numerous publications including the Journal of Organic Chemistry, Journal of the American Chemical Society, Organic Syntheses, Organic Reactions, and as the head editor of the Electronic Encyclopedia of Organic Reagents (eEros).
Dr. Paquette’s other honors include Sloan Fellow, Guggenheim Fellow, ACS Award for Creative Work in Synthetic Organic Chemistry, Arthur C. Cope Scholar Award of the ACS, the S.T. Li prize for Science and Technology and he was chosen as the Centenary Lecturer of the Royal Chemical Society, just to name a few. He has been a fellow of the Japanese Society for the Promotion of Science, and has been selected to serve as the Plenary Lecturer for more than a dozen international conferences. He is also the recipient of an honorary doctorate from his alma mater.
According to a nominator for one of his many awards, Dr. Paquette’s prolific career has resulted in remarkable contributions to numerous areas of relevance in the broad field of organic chemistry, including synthesis and properties of unusual molecules, natural products total synthesis, new synthetic methodology, rearrangement processes and stereoelectronic control. In the field of hydrocarbon chemistry, Dr. Paquette is best known for achieving the first total synthesis of the Platonic solid dodecahedrane in 1982, which still stands as one of the landmark achievements in the history of organic synthesis and hydrocarbon chemistry.

The CEM Internal Advisory Council, a grassroots committee of CEM students and postdoctoral researchers, created this workshop to inform the Center’s direction and improve the educational and research experiences of CEM students. POEM will be composed of tutorials by faculty, student talks, poster sessions, and will provide extensive opportunities for interaction between CEM students (on and offsite), and students at NMHU (New Mexico Highlands University), as well as CEM faculty. The workshop also provides a platform to CEM faculty for exchange of innovative ideas to further the research direction of CEM. This internal workshop is closed to the public.
