Concluding Remarks Future Prospects

This chapter is organized as follows. The approach highlighted here is described in section 17.2. Due to the special class of basis functions employed for the least-squares fit, the method is named combined hyperbolic inverse power representation or CHIPR from its initials, and uses the MBE as the starting point. Still in its infancy, the approach has been tested so far on tria-tomic systems that have been much studied by other schemes, namely H3 and HO2. Reasons for their choice are pinpointed in section 17.3, where the results obtained are reviewed. Section 17.4 gathers the concluding remarks and prospects for future work. 

The purpose of this review is to summarise the present status of this fascinating new area of endeavour, which has been termed directed evolution [8-10, 12,13]. We begin with a description of the relevant molecular biology methods, follow up with typical examples from the field of applications and end with concluding remarks concerning future prospects.

In the present chapter, rayon and other man-made cellulose fibers wUl be introduced in terms of properties and stracture. The compounding method to obtain the composites will be described briefly. PP-rayon composites will be considered in more detail as the practically most relevant class of this type of material at present arousing interest from the automotive industry. In another section rayon composites with poly(lactic acid) (PLA) and polyhydroxyalkanoates (PHA) will be studied as a promising bio-based and biodegradable alternative to conventional materials in durable applications, transport, and automotive industry. Finally, some concluding remarks will be given concerning future prospects of rayon reinforced thermoplastics and the problems to be tackled in future work. 

Conditions for collective, plasmon-type excitations will be addressed in Section 2.6. It will be shown that they can be fulfilled only for very large systems. Future prospects will be given in the concluding remarks.
