A comprehensive discussion of the key role of modern spectroscopic investigations in interdisciplinary materials science and engineering, covering emerging materials that are either absolutely novel or well-known materials with recently discovered, exciting properties. The types of spectroscopy discussed include optical, electronic and magnetic, UV-visible absorption, Rayleigh scattering, photoluminescence, vibrational, magnetic resonance, electron energy loss, EXAFS, XANES, optical tomography, time-resolved spectroscopy, and point contact spectroscopy. The materials studied are highly topical, with a focus on carbon and silicon nanomaterials including nanotubes, fullerenes, nanoclusters, metallic superconducting phases, molecular materials, magnetic and charge-stripe oxides, and biomaterials. Theoretical treatments are presented of molecular vibrational dynamics, vibration-induced decay of electronic excited states, nanoscale spin-orbit coupling in 2D Si-based structures, and the growth of semiconductor clusters.
Five questions dominated the ARW on Physics and Materials Science of High Temperature Superconductors, of which this book forms the permanent record. Briefly, these are: (i) How close are we to a unified theory? The consensus is that we are not. (ii) Flux pinning: can it be achieved in bulk materials? Still an open question. The following three questions are related. (iii) Can grain boundary contributions be brought under control? (iv) What is the real requirement for purity and general chemistry control? (v)What is the practical outlook for bulk products - tapes and wires? One of the conclusions is that the geometry and dimensions in thin films are the key parameters that facilitate the realization of high current densities and, consequently, their commercial application. On the other hand, the very large number of poorly understood microstructural, chemical and mechanical variables involved in the preparation of bulk materials are currently prohibiting large scale commercialization of wires and tapes.

This concise monograph traces Russian Marxism from its beginnings to mid-1977, shows how and why the party achieved power, how it has strengthened its position, and how it has undertaken to remold the country and to solve its internal problems. Wesson's study is the only up-to-date party history currently available. The book opens with background material on Russian discontent and endeavors to analyze the fundamental nature of Communist Party rule, taking into account new perspectives in Lenin's revolution, the Stalinist period, and the Khrushchev years, as well as the latest period not covered in earlier accounts. It treats the rise of Lenin, the struggle for power after Lenin and after Stalin, and the consolidation of Brezhnev's authority. As the most recent history of communism in the Soviet Union, it has great topical interest and is clearly written for the benefit of the student and general reader as well as the professional.
