Endroit : Pavillon Roger-Gaudry, salle G-615 à 11 h 00.
Cette conférence sera prononcée par Kristopher Harris, Ph.D. de l'Université McMaster, postdoctorant sous la supervision du Professeur Gillian Goward.
Résumé :There are many classes of inorganic material that display valuable functionalities. Often, the desirable properties arise only because of interplay between the components of a complex and heterogeneous material; furthermore, disorder, intermolecular bonds, and specific local dynamics may play a vital role in the material’s function. The key to understanding and controlling the behaviour is therefore likely to be found in successfully quantifying these characteristics. Solids NMR spectroscopy is ideally suited to studying this exact class of properties, and therefore occupies a central role in the seminar, though an array of other valuable tools will also be discussed where warranted. The chief focus of the seminar will be the local structures and dynamics in materials for lithium-ion batteries, but the discussion will also include a collection of other inorganic systems selected to explore the effects of intermolecular interactions, optical properties, atomistic dynamics, and the relationship of physical properties to molecular orbitals.
