New Challenges and Opportunities

The constraints discussed in this chapter represent new challenges and opportunities for improved membrane materials and technologies for downstream processing. 

The most difficult task in preparing this paper was the prognostication of the future I can only offer my own personal views. However, my perception is that we are at the threshold of major new challenges and opportunities for chemical engineers in fluid mechanics and transport phenomena. 

New challenges and opportunities for powder diffraction are emerging. Powder diffraction is a very active field. As in the past, progress will benefit from advances in instrumentation and computing Examples are ... 

Catalytic cracking is a very flexible process used to reduce the molecular weight of hydrocarbons. Today, fluid catalytic cracking (FCC) remains the dominant conversion process in petroleum refineries. Although FCC is sometimes considered to be a fully matured process, new challenges and opportunities in its application and a continuing stream of innovations in the process and catalyst field ensure that it will remain an important and dynamic process in the future of refining. 

Fluid catalytic cracking is sometimes said to be an evolved process. However, new challenges and opportunities are ever-present in its application, and constant innovations ensure that it will be crucial in the future of refining. 

The percutaneous toxicity of chemical warfare agents is primarily related to the rate and extent of percutaneous absorption which, in turn, is subject to a variety of environmental, biological and physicochemical factors. Understanding the basic mechanisms which control skin absorption is essential for developing effective pre- and postexposure medical countermeasures and progress in transdermal technology is likely to yield new challenges and opportunities in the future. 

During the past four decades that the author has been involved with both Industries, there have been many profound changes. No doubt the rate of change will accelerate, bringing new challenges and opportunities. If this work can, in some small way, help those involved to meet those challenges and to exploit the opportunities, it will have achieved its objective. 

Natural Polymers Their Blends, Composites and Nanocomposites State of Art, New Challenges and Opportunities... 

Abstract The present chapter deals with a brief account on various types of natural polymers such as cellulose, chitin, starch, soy protein, casein, hemicellu-loses, alginates, polylactic acid and polyhydroxyalkanoates etc. Blends, composites and nanocomposites based on these polymers have been very briefly discussed. Finally the applications, new challenges and opportunities of these biomaterials are also discussed. 

In summary, this brief overview is intended to provide a sampling of the ways in which studying protein structure and function in the genomic era furnishes new challenges and opportunities and is likely to give rise to a host of unexpected and exciting discoveries. 

This ongoing lO-development is conceived by the safety authorities to create new challenges and opportunities for managing risk, due to increased complexity and inherent dynamic potential.
