This is particularly true in the case of bioprocesses where the state of the living part of the system must be closely monitored. Extensive surveys have been published and several international conferences have been held on this topic. Furthermore, the last two decades have seen an increasing interest to improve the operation of bioprocesses by applying advanced control schemes. In particular, biological Wastewater Treatment Processes (WWTP s), more efficient than the traditional physico-chemical methods but at the same time... 

This volume of Advances in Chemical Physics is dedicated, by the contributors, to Moshe Shapiro, formerly Canada Research Chair in Quantum Control in the Department of Chemistry at the University of British Columbia and Jacques Mim-ran Professor of Chemical Physics at the Weizmann Institute, who passed away on December 3,2013. It focuses primarily on the interaction of light with molecules, one of Moshe s longstanding scientific loves. However, the wide scope of topics covered in this volume constitutes but a small part of Moshe s vast range of scientific interests, which are well documented in over 300 research publications and two books. 

In this review the new thrusts of advanced control theory into the four areas mentioned above will be discussed. The current state of control theory and practice for these areas will be mentioned, and new contributions which hold promise for future application will be outlined. Most of the literature cited in this review falls under the general classification of linear control theory, which in the author s opinion holds the most near-term promise for applications. Hence such topics as nonlinear estimation and control are not covered in any depth here.

Our intended audience is junior and senior undergraduate chemical engineering students. The book is meant to provide the fundamental concepts and the practical tools needed by all chemical engineers, regardless of the particular area they eventually enter. Since many advanced control topics are not included, those students who want to specialize in control can go further by referring to more comprehensive texts, such as Ogunnaike and Ray (1994). 

Since the fascinating azo BC offers an effective and convenient method to design advanced materials with more than two functionalities, it has become one of the emerging topics in novel azo materials. This chapter tries to introduce this field from the preparation method and basic properties to the control of their...

A considerable amount of attention has been devoted to this topic in recent years, particularly in view of the advances related to controlled radical polymerization [56-60]. 

In order to improve the properties of these unique polysaccharides and to develop new advanced materials, much attention has been paid to their chemical modification. These polymers have two reactive groups suitable for this purpose, namely, primary (C6) and secondary (C3) hydroxyl groups in the case of chitin whereas chitosan has additionally the amino (C2) group on each deacetylated unit. All these functions are susceptible to a variety of classical reactions which can be applied here in a controlled fashion to obtain a vast array of novel materials based on the two polysaccharides which can also be modified by either crosslinking or graft copolymerization. This topic has been extensively studied and thoroughly documented [5-7].
