ISBN This book gives a detailed and comprehensive overview of an important and rapid growing interdisciplinary fieldsmetal cluster. Chapter 1 is a general survey of the book that provides readers with a clear picture of metal clusters and cluster matter.

Here, the authors have done a good job by classifying metal clusters into three categories: very small clusters, small clusters, and large clusters.

By doing so, the authors have unified terminology used in the field and made further theoretical treatment more concise. Chapter 2 starts with the electrodynamic theory of large metal clusters. This is followed by a summary of the current quantum mechanic modes of small metal clusters.

Then, the electrodynamic models of cluster matter are discussed with emphasis on the effective media theory and aggregated metal cluster complex. An important concept introduced by the authors is that the effective dielectric constant of a small metal cluster is not only a function of the frequency but also a function of its physical dimension.

Detailed procedures are given for preparing metal clusters in gas phase, on surface, in solid matrix, and in solution. The advantages and disadvantages of nondestructive and destructive optical spectroscopic techniques are also discussed. Chapter 4 summarizes most important experimental results obtained before The authors have arranged the results in the same order as in Chapter 2: large metal clusters, small and very small metal clusters, and cluster matter.

The classical electrodynamic treatment has been quite successful in predicting both resonance frequencies and line shapes of optical spectra of large metal clusters.

For small and very small clusters, however, quantum theory must be applied. Overall, this book provides the theoretical concepts, experimental methods, interesting results, and current status of the field of metal cluster. References are quite extensive over through It is suitable for people in fields of metal thin films, colloid chemistry, heterogeneous catalysis, and, of course, cluster science.

The exit hole is usually circular, giving round fibers.

Other shaped holes are also employed that produce fibers with varying shapes. The extruded fiber is then often uniaxially stretched by take-up rollers rotating at different speeds.

The fiber stretching encourages the polymer chains to align on a molecular level producing increased strength in the direction of the pull. Water has been used for some systems, such as PVA, where the polymer is water soluble. It is produced by melt spinning in both a continuous filament and staple form. The die is d a spinneret. The number, shape, and size of the hole can vary considerably. The number les ranges from several to several thousand.

The next step is the incorporation of various additives—compounding. Typical additives include fillers, processing aids, activators, age resistors, sulfur, antioxidants, and antiozone compounds, extenders, plasticizers, blowing agents, pigments, and accelerators. The strength of many films is improve orientation, stretching.
