Description: Zinc oxide, already used millennia ago as a medicine and as an adjunct to brass production, has assumed a new importance in the modern world because of its native n-type semiconducting properties. It has, for instance, a relatively large (3.3eV) band-gap at room temperature. This leads to higher breakdown voltages, resistance to high electric fields, lower electronic noise and superior performance at high temperatures and powers. The band-gap can also be tailored by alloying with magnesium or cadmium oxides. The material exhibits other useful properties, such as a good transparency, a high electron mobility and a strong room-temperature luminescence; all of which are invaluable to the manufacture of the liquid-crystal displays of modern consumer goods. The present compilation comprises nearly 500 accounts of research on the diffusional behaviour of dopants and on the defects present in the wurtzite or zincblende structures. It is hoped that this handy compendium of data will be of value to those working on the tailoring of ZnO properties; especially with regard to the controversies concerning its doping behaviour.
Description: Volume is indexed by Thomson Reuters BCI (WoS). Public interest and concern about radiation damage effects has increased during recent times. Nuclear radiation proved to be a precursor for the study of radiation damage effects in solids. In general, all types of radiation, e.g. X-ray, gamma ray, heavy ions, fission fragments and neutrons produce damage effects in materials. Radiation damage latent tracks in solids find applications in nuclear and elementary particle physics, chemistry, radiobiology, earth sciences, nuclear engineering, and a host of other areas such as nuclear safeguards, virus counting, ion track filters, uranium exploration and archaeology. Radiation dosimetry and reactor shielding also involve concepts based on radiation damage in solids. This special volume consists of ten Chapters, including Review and Research Papers on various topics in this field.
Description: The nickel aluminide intermetallic is a particularly useful alloy for application at high temperatures because, unlike most materials, it exhibits the unusual property of becoming stronger with increasing temperature: depending upon the minor alloying additions, the 0.2% yield strength peaks at between 600 and 800C. The reason for this anomalous behaviour can be traced to the effect of the superlattice structure upon diffusional mass transfer and defect motion. The present volume contains a compilation (350 items, 176 pages) of data specifically covering the known diffusion and defect properties of this material.
Description: Carbon has always been an essential feature of human civilisation (not to mention the human constitution), whether as mere fuel, as an expensive bauble or as an essential component of those two supporting pillars (organic chemicals, steel) of the industrial revolution. Even since its recognition as an element, 2¼ centuries ago, it has never ceased to offer new surprises and properties. Just decades ago, students had to contend with only two main forms, graphite and diamond, but nowadays there is a plethora of nanotubes, fullerenes, graphenes, etc. The present volume offers a compilation (over 400 items) of data on mass diffusion, in all of the various known allotropes of carbon, spanning some 6 decades.
Description: The molecular dynamics technique was developed in the 1960s as the outgrowth of attempts to model complicated systems by using either a) direct physical simulation or (following the great success of Monte Carlo methods) by b) using computer techniques. Computer simulation soon won out over clumsy physical simulation, and the ever-increasing speed and sophistication of computers has naturally made molecular dynamics simulation into a more and more successful technique. One of its most popular applications is the study of diffusion, and some experts now even claim that molecular dynamics simulation is, in the case of situations involving well-characterised elements and structures, more accurate than experimental measurement. The present double volume includes a compilation (over 600 items) of predicted solid-state diffusion data, for all of the major materials groups, dating back nearly four decades. The double volume also includes some original papers: “Determination of the Activation Energy for Formation and Migration of Thermal Vacancies in 401.0 Casting Aluminum Alloy” (N.A.Kamel et al.), “A Study of the Effect of Natural Aging on Some Plastically Deformed Aluminum Alloys using Two Different Techniques” (N.A.Kamel), “Estimation of Crystalline Size of Deformed 5251 Al Alloy using PALT and XRD Techniques” (M.A.Abdel-Rahman et al.), “Determination of the Activation Energy for Formation and Migration of Thermal Vacancies in 2024 Aircraft Material using Different Techniques and Methods” (N.A.Kamel), “Annealing Study of Al-Mg Wrought Alloys using Two Different Techniques and Estimation of the Activation Enthalpy of Migrating Defects” (G.Attallah et al.), “Studying the Formation of Fe2SiO4 and Pearlite Phases in Iron-Silica Sand Nanoparticle Composites” (T.Ahmad et al.), “Studies of Knight Shifts and Hyperfine Structure Constants of Tl2Ba2CuO6+y” (M.Q.Kuang et al.).

Description: Volume is indexed by Thomson Reuters BCI (WoS). Heat transfer plays major role in many technical devises or in the formation of new materials. Heat transfer is based in three phenomena, namely conduction, convection and radiation. Understanding heat transfer at many levels, from atomic to macro, and its interaction with other physical phenomena has therefore long attracted the attention of many researchers in engineering and materials science and related disciplines. The present topical volume on "Heat Transfer Processes in Engineering Materials" captures a representative cross-section of some of the recent advances in the area of heat transfer. Reflecting the enormous breadth of the area, the range of topics covered is accordingly very large. Topics include the development and modification of the microstructure of materials. Technical applications such as casting problems, coal drying, air cooling systems and pyrolytic boilers. The prediction methods range from analytical to numerical methods such as the finite element method, the finite difference method and molecular dynamics simulation.

Description: Volume is indexed by Thomson Reuters BCI (WoS). This work reflects the wide and fascinating range of fields to which positrons have made important contributions. This covers, in particular, the development of low-energy (eV-keV) beams of essentially mono-energetic positrons, in the late 1960s, which opened the door to an even wider range of fundamental and technological studies: from surface physics to polymer films. In her introduction Professor Ganguly offers some background knowledge on the extent to which positrons have influenced and contributed to work in numerous fields.
