Selected papers from the symposium address chemical modification of alumina and other oxides and of silica, gas phase sorption on controlled surfaces, characterization of surface-bound substances, and general topics. The subject attracts interest from a variety of disciplines--separations, catalysis, bioengineering, electronics, among others. Represented here are the diverse techniques employed for investigation in a field that has grown from a trial-and-error technology to a science. Book club price, $47. Acidic paper.

Bioinert ceramics (zirconia, alumina) are used in medical devices in orthopedics and dentistry. Their surfaces may provide different functions: fixation of the device in the living tissue (e.g. dental implants), tribological role(joint substitutions),... In all cases the surfaces are treated to maximize their performance, but this modifications may entail negative consequences. The use of roughness to promote osseointegration of implants is a common practice, especially on dental implants. Roughening is often conducted by mechanical treatments, the most common being sandblasting. Therefore, chapter 2 focus on the implications of roughening by sandblasting on the mechanical behaviour of zirconia, alumina and a zirconia-alumina composite, and the differences between them. The work brought in chapter 3 was carried out entirely during a six-month secondment at CeramTec GmbH. In a bearing couple, lubrication mechanisms are complex and wettability and proteins play a yet-to understand role. The study compared the wettability of different materials, their ability to welcome protein adsorption and the effect of different cleaning procedures on wettability measurements and protein adsorption. Finally, the influence of the surface on cell activity is not driven exclusively by roughness: chemical modifications of the surface may enhance the perception of cells for the surface, and by careful tuning of the surface properties one may achieve a better integration without the downsides of roughness. In chapter 4, we explored a novel modification of zirconia, based on known techniques in chemistry, which introduces molecules with special functional groups capable of rendering the surface friendlier for cell adhesion, and opening the window for new exciting developments in the field of bioinert ceramics.

The research within this thesis is focused on the synthesis and characterization of a new generation of thin oxide layers with nanostructured pore morphologies. In the present work it was chosen to work with zirconia and hafnia derived materials, including related heterometallic compounds with, for instance, titanium as an additional element.
