Structure of sol-gel glasses

Bob Newport & Dave Pickup

In this session we will take a look inside a sol-gel glass, at the level of the atomic-scale structure.  The principal case studies will focus on silicate and phosphate glasses, including an overview of synthesis methods, potential applications, etc..  Some of the available advanced physical probe methods will be outlined, together with their major strengths and limitations, and these will be illustrated using published data.  Aspects of sol-gel processing and of the effects of chemical reactions (e.g. bioactive glasses exposed to body fluids) will be examined, including the use of in situ/time-resolved methods.  The presentation will be informal – questions/discussion is encouraged – and seeks only to provide a first introduction to the area.
