Plastics manufacturing is a highly interdisciplinary endeavor requiring knowledge related to materials science, physics, engineering, and management. Because of this diversity, the plastics process engineer interacts with many stakeholders including customers, designers, materials suppliers, machine builders, mold/die suppliers, systems integrators, operators, quality engineers, managers, and others. With so many stakeholders involved, it isn't surprising that many plastics manufacturing processes are not precisely engineered systems. The resulting processes can be poorly designed, requiring too much investment to achieve too little productivity. This book was written to educate and support plastics processing engineers, but it is also highly useful to others involved with plastics manufacturing who are performing process development, research, and even machinery design. A manufacturing systems engineering approach was used to provide guidance about plastics manufacturing as an integrated system with broadly applicable analysis of the underlying subsystems.

"Nanotechnology" isa broad term that includes aspects of materials science, mesoscopicphysics, organicandinorganicchemistry, na- electronics, atmosphericchemistry, airpollution, and other?elds. The technology is very muchincurrent focus-at the beginning of the Third Millennium-and raises hopes for environmentally benign, resource-lean manufacturing of products of manykinds. One precursor to present-day nanotechnology used porous coatings, comprised of "ultra?ne" particles withdimensions inthe nanometer range, for absorption of thermal radiation on thermocouples, bolometers, and the like. These particles were prepared by gas-phase syntheses, speci?cally using species formed by nucleation andgrowth from a metalvapor - dergoing coolingby collisions withinert gas molecules. Such "inert gas evaporation" was explored inthe 1920s and 1930s see, for example, A.H. Pfund, Phys. Rev. 35 (1930) 1434]andwas investigated in moredetail in the 1960s and 1970s see, for example, K. Kimoto et al., Jpn. J. Appl. Phys. 2 (1963) 702; C.G. Granqvist and R.A. Buhrman, J. Appl. Phys.47 (1976) 2200]. Improved analytical capabilities(electron microscopy)as well as new applications (selective absorption of solar energy) were twoofthe r- sons for the renewed interest. Today, gas-phase synthesis of nanoparticles constitutesthe foundation for a pro?table butstill small industry. Aerosols, i.e., dispersions or suspensions of particles ina gas, form the background ?eld for contemporaryefforts in gas-phase nanotechnology. Interest inaerosol researchhistorically arose from the issues of atmospheric chemistry and physics, human health protection, and airpollution. Today, aerosol researchengagesa vast array of efforts inthese and related ?elds, andelsewherein work identi?ed as nanotechnology.

In the years following the publication of Magnetic Methods for the Treatment of Minerals by Elsevier in 1987, many changes have taken place in magnetic technology. While fundamental and thorough, the above treatise re?ected pr- erences and philosophy of research and the development and application of magnetic methods as they were practiced in the second half of the last c- tury. Although demand for metals and minerals has not diminished, the d- inant drivers of the early 21st century di er signi?cantly from those of the late 20th. The priorities of nuclear power, defence, and energy-demanding and waste-generating bene?ciation of mineral resources are being replaced by those associated with technology sustainability, environmental and knowledge m- agement, recycling, and health care. Research priorities and product devel- ment of the last century cannot, therefore, satisfactorily meet criteria of the 21st century. Considerable technological progress has been achieved in areas such as - tomation, computerization, sustainable material science, laboratory and plant practices and separation equipment. New permanent magnetic materials, - vances in practical applications of superconductivity and availability of soph- ticated modelling tools have changed the technological landscape. As a result, innovation and technology transfer in magnetic technology have been rema- ably successful during the last two decades. The title of this monograph re?ects the fact that the book covers not only the application of magnetic techniques in the minerals industry, but also in recycling, environmental engineering and biomedical sciences.
