Description: Carbon nanotubes are one of the newest materials to be discovered, being barely 20 years old. They are also the most promising one, with one particular sample of multi-walled nanotube attaining a tensile strength of 63GPa, and with carbon nanotubes in general having a specific strength of up to 48000kNm/kg: effectively a direct exploitation of the covalent sp2 bonding between carbon atoms. Plastic deformation begins at about 5% strain. The nanotubes can be produced in lengths of up to 550mm, and thicknesses as small as 4.3Å; making them perfect reinforcement fibres for composites. They also have many other properties which may be useful in electronics, gas storage , etc. The present compilation focuses on the various characteristic types of defect which are found in carbon nanotubes, plus the relatively limited number of diffusion studies which have been performed. The 418 entries cover the period from 1994 to 2014.

This topical volume on Advanced Diffusion Processes and Phenomena addresses diffusion in a wider sense of not only mass diffusion but also heat diffusion in fluids and solids. Both diffusion phenomena play an important role in the characterization of engineering materials and corresponding structures. Understanding these different transport phenomena at many levels, from atomistic to macro, has therefore long attracted the attention of many researchers in materials science and engineering and related disciplines. The present topical volume captures a representative cross-section of some of the recent advances in the area of mass and heat transport. Reflecting the enormous breadth of the area, the range of topics covered is accordingly very large.

Description: The simple, empirical, surprisingly accurate and venerable Arrhenius equation, based upon the work of Van't Hoff, is very useful for summarising large bodies of experimentally determined diffusion data for a given host/diffusant system. It is the first port of call for any researcher planning new diffusion studies, or for engineers who need to estimate heat-treatment times in manufacturing processes. The present compilation covers Arrhenius parameters for the host-metals: aluminum, barium, beryllium, cadmium, chromium, cobalt, copper, gallium, gold, hafnium, indium, iridium, iron, lead, lithium, magnesium, molybdenum, nickel, niobium, palladium, platinum, potassium, rhodium, ruthenium, scandium, silver, sodium, tantalum, thallium, thorium, tin, titanium, tungsten, vanadium, zinc and zirconium. The 1315 entries cover the period from 1927 to 2013.

Description: The microporous aluminosilicate minerals known as Zeolites are invaluable as adsorbents, molecular sieves and catalysts because they possess a porous structure that can let pass or accommodate cations such as, Ca2+, K+, Mg2+, Na+, etc. These are nevertheless loosely held and can be easily exchanged for those in an adjacent solution. Movement of other materials through Zeolites is naturally an important factor. The present compilation consists of diffusion data. These represent, as far as possible, pure diffusion, shorn of other transfer mechanisms such as permeation. Most of the results involve well-known artificially produced Zeolites, but also include information on naturally occurring Zeolites such as analcime and clinoptilolite. The 290 entries, 22 figures and 67 tables cover the period from 1961 to 2014.

Description: The present issue comprises a compilation of data on diffusion in halides in either the crystalline or molten state; that is, diffusion in aqueous systems is not covered. The data cover a period of almost 50 years: from 1965 to the beginning of 2014. The over 700 entries, 205 tables and 34 figures will provide an invaluable wealth of information on diffusion in this class of material.

Description: Due to its small size, the hydrogen atom is, wanted or unwanted, an ubiquitous diffusant in many metallic systems. It has long been known for its harmful effect upon mild steel sheet; the deleterious phenomenon of hydrogen-embrittlement having been recognized since the early days of the industrial revolution. Its behavior in some metals is further complicated by its tendency to form hydrides with the metal, or with various non-metallic impurities. The ability of some metals and alloys to store large quantities of hydrogen – first recognized in the 19th century - is another complicating factor. The complexity of metal-hydrogen behavior was undoubtedly also the cause of the mistaken ‘cold fusion’ claims of the late 1980s. The present issue comprises a compilation of hydrogen diffusion and permeation data in metals. These data are believed to be ‘pure’: that is, free from the interfering effects of hydride formation, etc. The almost 600 entries, 201 tables and 41 figures cover the period from 1966 to 2013. These are supplemented by an original review, by T.B.Flanagan of the University of Vermont, which has as its subject, The Role of the Thermodynamic Factor in Hydrogen Diffusion in Metal and Alloy Membranes.

The special session "Fluid Flow, Energy Transfer and Design" held at the 9th International Conference on Diffusion in Solids and Liquids (DSL 2013) sheltered papers of different areas ranging from physics, mathematics and chemistry to engineering. It served as a link under which authors of different areas and backgrounds came together, and make their research accessible to the varied audience. In this sense worked to counter the possible divisive tendency. This special issue is a fitting tribute to the different views since this is not a divisive tendency but the seethe of science that shapes the ever-changing landscapes of our research world.

This special volume consists of eight chapters consisting of seven Review papers and one Research paper. “Luminescence Phenomena: An Introduction” is the first Chapter contributed by KVR Murthy and HS Virk. It explains the basic phenomenon of Luminescence: “Luminescence is "cold light", light from other sources of energy which can take place at normal and lower temperatures. The word luminescence was first used by a German physicist, Eilhardt Wiedemann, in 1888. In Latin ‘Lumen’ means ‘light’. The materials exhibiting this phenomenon are known as ‘Luminescent materials’ or ‘Phosphors’ meaning ‘light bearer’ in Greek. Luminescence is basically a phenomenon of emission of light from an insulator followed by prior absorption of energy from ionizing radiations like, X-rays, alpha, beta and gamma radiations. The energy lifts the atoms of the material into an excited state, and then, because excited states are unstable, the material undergoes another transition, back to its unexcited ground state, and the absorbed energy is liberated in the form of either light or heat or both. The excitation involves only the outermost electrons orbiting around the nuclei of the atoms. Luminescence efficiency depends on the degree of transformation of excitation energy into light, and there are relatively few materials that have sufficient luminescence efficiency to be of practical value”.
