  •  General Description of Research Goals of the Group

The principal aim of our group is to make use of the latest developments in synchrotron generated X-rays to study fundamental properties of condensed matter. At the present our primary efforts are directed at understanding the structural and statistical properties of the liquid surfaces. The research includes studies of liquid layers that are sufficiently thin that their properties are influenced by the surfaces.

These include the surfaces of liquid metals and alloys for which the interest is partially motivated by theoretical predictions regarding the interactions of the Fermi conduction electron liquid and the classical liquid of charged ions. More recently we have become interested in the surface properties of alloys that are relevant to the problem of developing lead free solders.

Other projects deal with the statistical and structural propertiess of two-dimensional phases that can be formed by monolayers of large insoluble molecules on the surface of water. Examples of which are metallic clusters, fullerene derivatives and synthetic polypeptides. We are also actively studying the effects of film thickness on the thermal flucutations and and structure of thin (i.e. 10 to 1000 Angstrom) films. of fluids adsorbed onto both liquid and solid surfaces.
