Many of the notes are hand-written on transparent plastic for use with an overhead projector. The file also contains some printed-out email correspondence with David Bucknall at Oxford University about a lecture. Topics include: Real time reflectivity measurements Polymer interfaces in the melt Neutron critical reflection as a tool for studying polymer mixing across an interface PS/PE system Neutron reflection experiments from melt polymers Polymer-Oligomer Interdiffusion Stereoregularity Effect of crystallanity on reflectivity [1990s-2001]
