Description: Diffusion is always central to many scientific and technological fields. From the recognition of Fick´s laws, up to the present day, there have been very important diffusion-based contributions made to fields such as biology, nanosciences, chemistry, physics, etc. Volume is indexed by Thomson Reuters CPCI-S (WoS)
Description: It is well-known, even at the most elementary level of scientific knowledge, that free surfaces have properties which make them differ from the underlying bulk material. In the case of liquids, it is common knowledge - even among laymen - that the liquid surface acts as though it were a distinct skin-like material. At a slightly more advanced level, it is known that the liquid surface will seek to minimize its total surface energy by minimizing its surface area; thereby affecting its local vapor-pressure and adsorption behavior. In the case of solids too, it has long been known that different crystallographic surfaces have different surface energies and that this can decide which surfaces ‘survive’ during crystal growth, and govern how solids - especially small particles - respond to prolonged annealing. However, although it was perhaps theoretically ‘obvious’, it is only relatively recently (since the 1950s) that it has come to be realized that solid surfaces will seek to minimize their total surface energy not only by minimizing their area, but also by changing their local surface structure. This process has come to be known as surface reconstruction. Study of this phenomenon has exploded in interest in recent years, partly because of the ever-increasing sophistication of the experimental techniques available for examining surfaces in the required detail, and partly because of the importance of the phenomenon in such fields as catalysis and layered (epitaxial) construction of semiconducting devices.

Description: The goal of this special volume was to provide a unique opportunity to exchange information, present the latest results and to review relevant issues in contemporary diffusion research. Volume is indexed by Thomson Reuters CPCI-S (WoS).
Description: This eleventh volume in the series covering the latest results in the field includes abstracts of papers which have appeared since the publication of Annual Retrospective X (Volume 272). As well as the 295 metals abstracts, the issue includes – in line with the new editorial policy of including original papers on all of the major material groups: “Structural and Electron-Hopping Studies of Pr- and Nd-Substituted La2/3Ba1/3MnO3 Manganites” (H.Abdullah and S.A.Halim), “Recrystallization Annealing of Cold-Rolled 9Cr-1Mo Ferritic Steel Containing Silicon” (M.N.Mungole, M.Surender, R.Balasubramaniam and S.Bhargava), “Quantitative Concept for Morphological Stability Analysis of Solid/Liquid Interface in Rapid Solidification of Dilute Binary Alloys” (M.Draissia), “Studies of the Spin Hamiltonian Parameters for NiX2 and CdX2:Ni2+ (X = Cl, Br) (Z.H.Zhang, S.Y.Wu, X.F.Wang and Y.X.Hu).

Description: Given that the basic purpose of all research in materials science and technology is to tailor the properties of materials to suit specific applications, phase transformations are the natural key to the fine-tuning of the structural, mechanical and corrosion properties. A basic understanding of the kinetics and mechanisms of phase transformation is therefore of vital importance. Apart from a few cases involving crystallographic martensitic transformations, all phase transformations are mediated by diffusion. Thus, proper control and understanding of the process of diffusion during nucleation, growth, oxidation, sintering, etc are essential for optimising the properties of materials to meet specific needs.
Description: This tenth volume in the series covering the latest results in the field includes abstracts of papers which appeared between the publication of Annual Retrospective IX (Volume 265) and the end of May 2008 (journal availability permitting). As well as the 452 metals abstracts, the issue includes – in line with the new editorial policy of including original papers on all of the major material groups: “Defect Investigation of Plastically Deformed Al 5454 Wrought Alloy Using PADBS and Electrical Measurements” (Abdel-Rahman, Kamel, Lotfy, Badawi and Abdel-Rahman), “Activation Enthalpy of Dislocation Migration in Aircraft (Aerospace) (2024) Alloy by Positron Spectroscopy” (Abdel-Rahman, Abdallah, Hassan and Badawi), “Effect of Irradiation Dose on AlCu6.5 Alloy using Positron Annihilation Doppler Broadening Technique” (Abdel-Rahman, Lotfy, Abdel-Rahman and Badawi), “Dependence of Mono-Vacancy Formation Energy on the Parameter of Ashcroft's Potential” (Ghorai), “X-Ray Characterization of Ag Impurities in Na1-xAgxCl” (Hazeen, Syed Ali, Prema Rani and Saravanan), “Self-Organization Behavior of Sub-Micron CdO Grains Grown during Vapour-Solid Transition” (Zhang, Wang and Li), “Studies of the Local Structure and the Spin Hamiltonian Parameters for Co2+ in CaTiO3” (Lu, Wu, Zhang and Wei).
Description: Diffusion-controlled processes still remain the most important and interesting phenomena in materials science. Among the problems which are currently to the fore, are the synergy of diffusion and morphological evolution, the initial stages of solid-state reactions, the analysis of nano- materials and related phenomena, thermo- and electromigration, and the reliability of solder joints and interconnects in microelectronic devices. A number of challenging problems still remain within the “classical” areas of nucleation, reactive- and inter-diffusion, phase growth in multicomponent and binary systems, and decomposition and ripening.
