Looking to the Future

Research and development into polymer electrolyte battery systems continues, yet many unsolved and controversial issues, particularly relating to the inadequate understanding and control of ion dissociation and the relative mobilities of the ions, remain. Modem computational resources now allow the structures of complex systems such as polymer electrolytes to be simulated and evaluated. Computer simu-

To the frequently asked question of what could I have achieved if I had not left in 1956, I have no definite answer. I believe, however, that we should look to the future and not second-guess the past. It is the future that really counts, and the key to the future (not only in Hungary but worldwide) is a good education. Only with a good education can the younger generation succeed, but of course circumstances, desire, and ability (as well as luck) are also important. 

To enable those engineers engaged in plant engineering to look to the future, the Institution of Plant Engineers has formulated a simple procedure for recording an engineer s attendance at activities, which contribute to CET and have been approved by the Institution for that purpose. Further information may be obtained from the Institution.

We hope that this review of chiral sulfur compounds will be useful to chemists interested in various aspects of chemistry and stereochemistry. The facts and problems discussed provide numerous possibilities for the study of additional stereochemical phenomena at sulfur. As a consequence of the extent of recent research on the application of oiganosulfur compounds in synthesis, further developments in the field of sulfur stereochemistry and especially in the area of asymmetric synthesis may be expected. Looking to the future, it may be said that the static and dynamic stereochemistry of tetra- and pentacoordinate trigonal-bipyramidal sulfur compounds will be and should be the subject of further studies. Similarly, more investigations will be needed to clarify the complex nature of nucleophilic substitution at tri- and tetracoordinate sulfur. Finally, we note that this chapter was intended to be illustrative, not exhaustive therefore, we apologize to the authors whose important work could not be included. 

Current views on the surface enrichment of one component over another in alloy systems are, surprisingly, more a consequence of gas titration and Auger electron spectroscopy than XPS and UPS. There is little doubt, however, that looking to the future XPS will provide important clues regarding the mechanism of bimetallic catalysts, the significance of promoters. 

The quartet of risk assessment chapters is followed by a look at the risk management practices of regulators and the ways in which risk assessment results are used. As is expected, the concluding chapter looks to the future. 

Before looking to the future, it will be useful to look back at some issues related to risk assessment and management that have so far been ignored. The issues are not so much technical as they are social and political, and to ignore them completely could leave the misleading impression that all the scientific and policy questions we have discussed are interesting matters for scholarly debate, and not much else. We shall not make this mistake.

The fnndamental differences between chemical and biological agents are very important as we look to the future. Chemical agents are volatile and dermally active and it is immediately apparent when there is hnman contact with a chemical agent. Biological agents, however, are not volatile, not dermally active, and...

Preclinical testing and development and development of new and coprocessed excipients (Chapters 3, 6, 9, and 20) This section describes the type of preclinical testing that is required in support of the development and registration of new excipients and presents a case study for successful development of a novel excipient. Lastly, Chapter 20 looks to the future and identifies excipients needed for innovative biotechnologically derived dosage forms. 

Although such studies are in their early stages, this example clearly demonstrates that we have the measurement tools to investigate the complex interaction of hydrodynamics and chemical kinetics in the complex porous medium represented by a fixed bed. Looking to the future, we may expect experiments of this nature to demonstrate how a catalyst with intrinsic high selectivity can produce a far wider product distribution when operated in a fixed-bed environment as a result of the spatial heterogeneity in hydrodynamics and hence, for example, mass transfer characteristics between the inter-pellet space within the bed and the internal pore space of the catalyst.
