The theory that results from the investigation of the dynamics of solute distribution between the two phases of a chromatographic system and which allows the different dispersion processes to be qualitatively and quantitatively specified has been designated the Rate Theory. However, historically, the Rate Theory was never developed as such, but evolved over more than a decade from the work of a number of physical chemists and chemical engineers, such as those mentioned in chapter 1.

The professional organization for chemists and chemical engineers in The Netherlands. 

A professional organization of chemists and chemical engineers. Conducts studies and surveys professional and student conferences and programs administers grants and fellowship programs maintains extensive chemical databanks, online services, and more than 33 divisions and hundreds of subcommittees covering all aspects offundamental and applied chemistry. Elelps interpret technical data and refers citizens to local scientists.

It is hoped that the hook will he of value to chemists and chemical engineers who are engaged in the manufacture of enantiopure products, and that they will sucess-fully apply some of the techniques described. In this way, an avenue will he provided for further progess to he made in this important field. 

What impressed me particularly was the wealth of high standard theoretical electrochemistry in discussions of the mechanism of NEMCA, for one seldom sees publications showing so much erudition in the theory of electrified surfaces. On the other hand, the book contains a very full treatment, rich in examples, of the practical and experimental side of NEMCA and thus will be attractive to the chemists and chemical engineers who serve in corporate research laboratories. It is likely to lead to advances in industrial... 

Facilities for separating steam from brine and for power generation were designed by mechanical, chemical, and electrical engineers. Dissolved salts in the brine cause severe scaling and corrosion in wells and pipelines. Chemists and chemical engineers developed new production techniques to overcome these problems, as well as pollution control technology for the operation. 

The Division of Chemical Sciences in OER supports basic chemical research. The primary involvement of chemical engineers with this program has been in the areas of catalysis and separations. Given the broad range of energy apphcations in which the structure and chemistry of interfaces is important, the committee recommends that the Division undertake an initiative in the chemical control of surfaces, interfaces, and microstractures. This would include support of work by both chemists and chemical engineers in the areas of surface chemistry, plasma chemistry, and colloid and interfacial chemistry. 

Whilst LCA is a powerful tool, which will become increasingly useful, as it is refined and becomes more objective, its complexity and cost, and the length of time taken to carry out a full analysis make it an impractical tool to use on a day-to-day basis for research and development chemists and chemical engineers. What is really required for most practising technologists is a simple set of metrics to aid the decision-making process involved in choosing one synthetic route or product over another.

What is very important in process development is the personnel overlap when changing the scale of the process. The head of the team that is to continue the development of a process should be involved in the research on smaller scale. Also, an important member or head of the team in the smaller scale research should participate in the further step(s) of process development. Often, a parallel operation of teams is required instead of operation in series. A pilot plant, mostly composed of existing equipment items in a company, is often required as the final step in process development. A verification of procedures and models is usually not necessarily the main objective of pilot studies. The most common reason for manufacture at pilot scale is the production of kilograms of the product for market purposes and toxicity tests. A close interaction between chemists and chemical engineers is necessary at all stages of process development. 

A book like the present one, which is not intended as a textbook for students, cannot be written by a single author. In fact, it is a multidisciplinary subject and the authors have not tried to omit all jargon and the flavour of the various disciplines involved. The consequence, of course, is that parts are not easy to understand for chemists, while others are difficult for chemical reaction engineers. It is hoped that this book will strongly contribute to bridging the gap between chemists and chemical engineers in the field. The authors will be grateful for comments from the readers. 

Rapid and reliable detection of dangerous disease organisms, highly toxic chemicals, and concealed explosives (including those in land mines), is the first important step in responding to threats. The next important step for chemists and chemical engineers will be to devise methods to deal with such threats, including those involved in terrorist or military attacks. 

Finally, it is critical to recognize that this report is missing one serious component the future discoveries that we do not see clearly from our present position. The history of science repeatedly shows that major discoveries open up whole new areas of understanding and of practical applications that were not anticipated. The aim of this overview is not to attempt to predict the future with great clarity but rather to be certain that the future is as rich and productive as it can be. But as we examine the future of our fields, there is one prediction we need to make Chemists and chemical engineers will come up with inventions and discoveries that are not encompassed in any such survey, and we will all say— why didn t we think of that ...
