Abstract: Since their first application to the vitreous state during the 1960s, the quality of the data obtained from neutron scattering experiments has vastly improved, mainly due to the development of high-flux neutron sources, and as the result of improvements in both neutron detectors and their associated electronics and data storage. The present lecture will review the role of modern neutron scattering techniques in the study of the atomic and magnetic structure and dynamics of inorganic glasses and other amorphous solids. The techniques to be discussed include neutron diffraction (structure), magnetic diffraction (magnetic ordering), inelastic scattering (vibrational density of states), quasielastic scattering (molecular rotation) and small-angle neutron scattering (longer-range fluctuations). The information that can be extracted using these techniques is illustrated with examples taken from papers by the author and his coworkers, and conclusions are drawn with respect to the present state of knowledge concerning the structure of the amorphous state.

Biography: Before his early retirement at the end of 2007, Professor (Emeritus) Adrian C. Wright was Professor of Amorphous Solid-State Physics at the University of Reading (U.K.). He received his B.Sc (Chemistry, 1965), Ph.D. (Physical Chemistry, 1970) and D.Sc. (1987) degrees from the University of Bristol (U.K). His research interests comprise neutron scattering and modelling studies of the structure and dynamics of a wide range of inorganic glasses and other amorphous solids, including silicate, borate, borosilicate, phosphate, chalcogenide, and fluoroberyllate glasses, and he has over 200 publications in the scientific literature. Professor Wright has been the recipient of several honours/prizes, including Fellowship in 1995 of both the American Ceramic Society and the (British) Society of Glass Technology. In 1990, he shared the Worshipful Company of Glass Sellers of London Award, and in 1996 received the American Ceramic Society Glass & Optical Materials Division George W. Morey Award for his establishment of the field of Amorphography. He also presented the 2006 Samuel R. Scholes Lecture at the New York State College of Ceramics, and was made an Honorary Fellow of the Society of Glass Technology in 2009. More recently, he shared the 2012 Otto Schott Research Award, for “his lifelong outstanding scholarly work devoted to the experimental study of glass structure in general” and, at the MS&T Meeting in Salt Lake City (October 2016), he will be made a Distinguished Life Member of the American Ceramic Society. He was President of the Society of Glass Technology from 2002 to 2004, and has served on both the Steering Committee and Council of the International Commission on Glass. The 6th International Conference on Borate Glasses, Crystals & Melts (Himeji, Japan, 18-22 August 2008) was held in his honour, and to mark his retirement.
