6. Redefines Itself in Era of Global Change ※ Globalization of business & technologies - How to conduct research and develop new technologies effectively and rapidly → cost-effective products and processes - How to share and transfer technologies within and across industries quickly & effectively - How to enhance and grow business : avoid depletion of national resources - How to share effectively the wealth of information and data - How to establish a global work force, moving people from one location or activity to another for education and employment - How to have a successful career and financial security as a chem. engineer while working for several organizations ※ Remark - make more with less & make it better, cheaper, faster - desire to change and develop new technology - emerge from the era of confrontation to one of the consensus building

7. Future Progress → health, environment, economic prosperity: social goals. 1. Environmental issues - reducing environmental fallout / conserving energy 2. Advanced materials: ① ceramics ② new specialty polymer(engineering) ③ org. ↔ inorg.(composite materials) → echo-harmonized technology (industry + man) → designed based on their fns & applications 3. Infrastructure investment in public works, housing & power 4. Change to small scale production of higher value products such as superconductors, catalyst, functional polymers, membranes, medical/pharmaceutical products & sensing devices. 5. Medical technology, food production, biomedical engineering of artificial organs, drug delivery system 6. Interdisciplinarity gives the chance for real progress

8. ※ The chemical industry is not a growing industry - current situation is simply a business cycle that will one day reverse - Chem. engineer ← farmer - Chem. engineer ← civil engineer : sustaining the infrastructure that exists and works for large organization Third Paradigm Chem. engineer must now develop a multi-scale & multi-objective approach aimed at a global optimization of production processes

9. New Research Opportunity 1. Increase productivity & selectivity through intelligent oprn and multi-scale control of processes: catalysts development, micro-technology, smart fluid dynamics 2. Design of novel equipments ↔ based on scientific principles & new modes of production : multi-functional reactor with higher yields : low cost module (safe, reliable, clean, cheap, easy to control) 3. Development of formulation eng. (with special emphasis on solid eng.): control of end-use properties (color, odor, flowability, sinterability) 4. Multi-scale application of computational chem. eng. to real life situations: from nano-scale to mega-scale modeling

10. Chem. Rxn. Eng. → brings diversity of inputs to process design 1. Multi-scale approach to process design / multi-objective task ← micro-scale plants design ⅰ ) process & product safety ⅱ ) environmental compatibility ⅲ ) waste minimization : higher selectivity 2. Minimization: mini-chemical systems (ex : hazardous materials) → produce on-site 3. Micro-plants ※ On the multi-scale approach the micro-reaction parallel processing from bench scale to pilot reactor are envisioned : as soon as laboratory data are sufficiently promising, engineering studies begin to look at the pilot-scale issue that are included in the procedure and information in feed back to the chemists so they can consider the ramifications of any problems.

11. Chemical R&D (I) 1. Chemical R&D ↔ don't bury it yet - chemical - related R&D is far from dead and has never been more important that ever - needs new technology : not cost & not service - restructures its R&D → making it more value oriented 2. Technology ← (future) petrochemical R&D 1) lies in adding value in developing - polymer feedstocks - intermediates - moving closer to the customer 2) is forced to become more efficient with their resources - decrease in R&D in the oil industry does not diminish its importance

12. Chemical R&D (II) 3) is cutting out R&D with little value (R&D : quicker results, immediate savings) - advances in future research will probably be at the boundaries of technical areas including physics, chemistry biotechnology, biochemistry, nanotechnology and materials science, etc. 4) claims new products, not product development 3. The best reason for continuing R&D is that technology continues to advance → technology has not yet peaked ex) genetically engineered cotton, new polymers, new composites, new materials from biotechnology ⇒ too many undiscovered materials.
