Carbon is unique in the range of structures and properties that are displayed by its material forms. The bonds in diamond, within the plane ofgraphite and in the fullerene molecules, C, are the strongest covalent bonds possible. This strong covalent bonding 60 leads to some exceptional intrinsic properties, examples ofwhich are: the greatest Young's modulus (in diamond, within the graphite plane and in single walled nanotubes) the highest room temperature thermal conductivity (in diamond and within the graphite plane) high hole mobility in doped diamond exceptional thermal stability ofthe...

Synthesis is a crucial component of future CAll s;ystems. The competitive edge of IC desiBn will most probcbly come frc*'1l the use of effective synthesis tools. A complete synthesis system should generate layout masks from a high-level algorithmic, behavioral or functional des- cription of a VLSI systen, [1 description of the target tech- nology and a description of the constraints and cost func- tions. The design should be completed in reasonable time and with the quality a human designer could obtain. Working designs have been produced with silicon compilers, but the quality of the design...

Over the past two decades, two-phase flow and heat transfer problems associated with two-phase phenomena have been a challenge to many investigators. Two-phase flow applications are found in a wide range of engineering systems, such as nuclear and conventional power plants, evaporators of refrigeration systems and a wide vari ety of evaporative and condensive heat exchangers in the chemical industry. This publication is based on the invited lectures presented at the NATO Advanced Research Workshop on the Advances in Two-Phase Flow and Heat Transfer. The Horkshop was attended by more than 50...

This book contains the majority of the papers presented at the NATO Ad vanced Research Workshop (ARW) held in Burlington, Vermont, USA on October 12-15, 1992. This ARW was the first of its kind to address the subject of intrinsically conducting polymers with an emphasis on processing and technological applications. The NATO ARW format was followed in that the subjects addressed here were limited in number but discussed in detail with the attendance being limited to a small number of selected scientists. The ARW brought together lecturers who are leaders in their respective fields from a wide...

Polymers, main components of plastics and rubbers, are being discarded in increasing quantities. But this waste can also be considered as plastic gold'. Public concern, coupled with the inherent value of the material, means that recycling is imperative. The present book presents a survey of current knowledge in the form of case studies, including current legal and educational issues. Topics covered also include regulation and practice in NATO countries, the economics of recycling, the reprocessing of single polymers and mixtures, and future prospects and strategies.

Several formerly independent trends including the in creasing rate of technological change, the demand for greater efficiency and productivity in R&D and innovation, and the need for applying technology to the solution of pressing social and economic problems have recently begun to reinforce each other resulting in renewed interest in technology trans fer activities and research. The proliferation of research efforts in the U. S. and Western Europe, increased corporate and governmental efforts to develop mechanisms and incentives for transfer and the growing closeness between transfer and...

Modulated Structure Materials arise in two basic ways. One is through the natural tendency that certain materials have to develoo stable modulations. Tynical examples of this catenory are the lonn oeriod superlattices, the spinodal alloys and other ordered structures. Another way to introduce nodulation into a basic is throuqh our own intervention, that is ~v artificial structure techninues. Such examples as the conposition nodulated films and the seniconductor superlattices have recently received apnreciable attention not only for their noble and unusual nrooerties but also for their...

Most water systems in the industrial regions of the world are already developed. At the same time they are highly complex. This is true with respect to physical configuration, managment, operation, political goals, environmental interactions, etc. Thus the basic systems are already in place. This realization is the starting point for any new water developments and for operation. From this we conclude that whatever we do to meet new exigencies requires an understanding of the presently in-place complex water systems. Their operation is the important thing. And how can we adjust their operation...

Prior to the so-called "energy crisis" of 1973, energy played a relatively minor role in our daily lives.and received limited attention from economists, planners and politicians. As a means of production its share in the total cost of the average product was considerably less than 10%. After the decisive events of 1973/74 however, all of this is changed. Energy now affects our daily lives more than anything else; it is the most current issue in business circles, the academia, the civil services and politics; and it is likely to become the most important factor in a potential international...
