Mainstreaming integration

Feedstocks pose challenges to mainstream integration of technologies. Three prominent issues are ... 

Plasma fractionation is unusual in pharmaceutical manufacturing because it involves the processing of proteins and the preparation of multiple products from a single feedstock. A wide range of unit operations are utilized to accompHsh these tasks. They are Hsted in Table 3 some are common to a number of products and all must be closely integrated. The overall manufacturing operation can be represented as a set of individual product streams, each based on the processing of an intermediate product derived from a mainstream fractionation process (Fig. 1). 

It is this integrative attitude that today characterizes most of the work in the area of intelligent systems for process engineering, as the editors of this volume have indicated in a recent review article. (4) It is this need for integrative approaches that has moved the applications of artificial intelligence into the mainstream of engineering activities. This is certainly the pivotal feature that characterizes the ten paradigms discussed in the subsequent chapters. 

In short, momentum for the project has been established. Publication of the Companion by the ACS represents a key step in making this material an integral part of the curriculum. The ACS will encourage use of the instructional packet not only by teachers, the primary targeted audience, but also by textbook authors and publishers. Incorporation of materials chemistry throughout introductory chemistry texts will be a certain sign that the discipline has entered the mainstream. As one of our committee members noted at the outset of this project, if 10% of all of the ex-... 

Questions regarding applicability of particular technologies to particular applications must, of course, be resolved eventually. However, mainstream focus has been on achieving adequate TFT device and circuit performance to support the control, computation, and communication functions for a wide range of potential applications. As satisfactory electrical circuit performance is attained for additional functionality, questions that relate to the quality of other device types, their integration into an overall process flow, and perhaps most importantly, the robustness and stability of the final product, will receive much more attention.86-88... 

The introduction of these alternative approaches has permitted the direct trans-ferral and smooth integration of many versatile solution phase reagents from mainstream chemistry catalogues straight into practical protocols for use in com-hinatorial parallel hbrary generation thus broadening the amenable chemistry base. As with aU procedures it is the flexibihty and synthetic scope provided by these simple operations that has enhanced their utility as alternative reaction conditions and purification strategies. 

As such one could expect that as PAT becomes better understood and used within pharmaceutical and biopharmaceutical, other areas, especially related to energy production through biobased platforms, will be a natural area for PAT to develop into an integral part of manufacturing. Perhaps it will even become mainstream in areas that originated some of PAT s tools (e.g., MSPC) like in sophisticated chemical processing. 

Silicon Epitaxy. A critical step in IC fabrication is the epitaxial deposition of silicon on an integrated circuit. Epitaxy is defined as a process whereby a thin crystalline film is grown on a crystalline substrate. Silicon epitaxy is used in bipolar ICs to create a high resistivity layer on a low resistivity substrate. Most epitaxial depositions are done either by chemical vapor deposition (CVD) or by molecular beam epitaxy (MBE) (see Thin FILMS). CVD is the mainstream process.
