SAMs are ordered molecular assembHes formed by the adsorption (qv) of an active surfactant on a soHd surface (Fig. 6). This simple process makes SAMs inherently manufacturable and thus technologically attractive for building supedattices and for surface engineering. The order in these two-dimensional systems is produced by a spontaneous chemical synthesis at the interface, as the system approaches equiHbrium. Although the area is not limited to long-chain molecules (112), SAMs of functionalized long-chain hydrocarbons are most frequently used as building blocks of supermolecular stmctures.

The class of polyester-based liquid crystal polymers (LCPs) represent one of the most attractive materials in the field of engineering thermoplastics because of their superior mechanical properties, heat resistance, accuracy of dimensions, moldability and the excellent balance of these properties [1-5]. LCPs have been recently expanding their applications, in particular, those for precision electronic parts appropriate for surface mount technology (SMT). 

Tribology is the branch of science and engineering of surfaces in relative motion. Included are issues of friction, wear, and lubrication of surfaces. Modem technology has enabled the study of these characteristics in a number of different ways. These studies have given rise to a new branch atomic-scale tribology. This branch deals with issues and processes from atomic/molecular scale to microscale. These... 

Dr. Thomas Chandy is a research associate in the Division of Chemical Engineering Material Sciences, Biomedical Engineering Institute and Interventional Cardiology Laboratories at the University of Minnesota. He has over two decades research experience at Sri Chlia Tvunal Institute for Medical Sciences Technology, Trivandrum, India, in the area of biomaterial surface engineering and blood biomaterial interactions. More recently. Dr. Chandy and Dr. Rao have focused their research on platelet biomaterial interactiorrs and development of assist devices for cardiovascular applications. They continue to be active in this newly evolving area of research. 

This section will describe a robust method for engineering a binding protein of interest using yeast surface display technology. Similar methods for gene engineering via yeast display have been reported (9, 31, 32), and slight variations may be used for particular applications to attain optimal results. 

The separation of soluble PTC is a matter of concern in the industry not only due to environmental considerations, but also due to contamination of the product with the catalyst. Further research should be oriented towards development of novel catalyst separation techniques and of novel reactor-separator combo units. As outlined before, the development of a membrane reactor with PT catalyst immobilized on the membrane surface seems to be a novel and viable candidate for accomplishing PTC reactions on an industrial scale. Another aspect of PTC which needs urgent consideration is the development of engineering technology for immobilized PTC. This would require the development of supports with low diffusional limitations and with the right hydrophilic-lipohilic balance to ensure adequate contact of the aqueous and organic phases with the supported catalyst.
