Description:

The present collection of papers from 12th International Conference „Local Mechanical Properties“ which was held on November 04.- 06.2015 in Liberec, Czech Republic presents current publications of conference participants from several countries .

Besides the traditional research in area of mechanical properties of different metallic materials, composites, polymers was focused attention also on research of thin layers and nanomaterials. The significant potential of application of these new materials significantly affects on research activities of academia. Future application of innovative materials in different areas of human activities, already requires from researchers the definition of materials properties on atomic level. Conference by its content contributed to the deepening of knowledge about the internal structure of various materials, their mechanical and tribological properties.

Description: This topical volume on "Recent Developments of Diffusion Processes and their Applications: Fluid, Heat and Mass" addresses diffusion in a wider sense with a special focus on technical applications. Diffusion phenomena play an important role in the development of modern engineering materials and related fields. 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 diffusive transport. Reflecting the enormous breadth of the area, the range of topics covered is accordingly very large. Topics include classical mass diffusion problems such as phase transformations, corrosion behavior, thin layers and microstructures. Technical applications related to fuel production and energy conversion, biological and biomedical material are treated. Many of these topics are related to experimental measurements and methods as well as simulation and approaches to predict properties and processes.

Description: Fluid flow, thermodynamics and heat/mass transfer are nowadays central pillars of science and technology. They have been central to the development of our civilization because we use them not only to understand natural-world phenomena but also to achieve incremental improvements in technology. The special session “Fluid Flow, Energy Transfer and Design” held at the 10th International Conference on Diffusion in Solids and Liquids (DSL 2014) includes papers of different areas ranging from physics, mathematics and chemistry to engineering and provided several contributions for this topical volume. Other experts in the field of heat and mass transfer were as well invited to contribute to this volume.

Description: It is pertinent to note that Luminescence phenomenon has once again occupied a central stage with the announcement of Nobel Prize in October 2014 to three Japanese scientists. The discovery of Galium Nitride proved to be a revolutionary step forward in creation of Blue LEDs. With the advent of LED lamps we now have more long-lasting and more efficient alternatives to older light sources. The Volume under reference consists of 9 Chapters, written by experts in the area of Luminescent Materials. First 5 Chapters are contributed as Review Papers and the last 4 are based on Research Papers.Chapter 1 is contributed by H.S. Virk, editor of this Volume, under the Title: “History of Luminescence from Ancient to Modern Times”. It traces the history of Luminescence based on E. Newton Harvey’s 770 page volume, which is a Classic in this area and narrates interesting stories from ancient cultures to modern times. The author has summarized the results of investigations of Bangalore Group under Sir CV Raman, the Indian Nobel Laureate of 1930. He has called “The Physics Nobel Prize 2014,” an Award for Luminescence.Chapter 2 is contributed by Sanjay Tiwari and JV Yakhmi on an important Topic: “Recent Advances in Luminescent Nanomaterials for Solid State Lighting Applications”. In fact, the recent Nobel Prize 2014 in Physics has been awarded for development of Luminescent Materials. The authors write: “Luminescent nanomaterials have attracted great interest worldwide because of their unusual structural, optical and electronic properties as well as efforts to prepare miniaturised devices. By understanding and manipulating these properties, the performance of the resulting optical structure can be tailored for desired end-use applications”.Chapter 3: “Persistence Mechanisms and Applications of Long Afterglow Phosphors” is contributed by NPL, New Dehli Group of V. Shankar and D. Haranath. The authors present a broad review of long persistence (LP) materials that are a special kind of photon energy storage and conversion materials. These are also known as long afterglow phosphors or long decay phosphors (LDP). This review Paper covers the recent advances in the blue, green and red-emitting LP phosphors/nanophosphors, persistence mechanism involved and the basic problems associated with their luminescence efficiency and persistence times.Chapter 4 by the Group of SK Omanwar: “Exploring Synthesis Techniques for Yttrium Based Phosphors” is focused on synthesis techniques developed by author’s group. An inter-comparison of various techniques is listed and data presented in 9 tables. The synthesis methods of yttrium based phosphors in terms of the particle sizes, morphology, required temperatures for synthesis, cost required for synthesis, and required time, are presented in this review in detail.Chapter 5 is contributed by the team of BP Chandra, a renowned scholar in ML, under the title: “Mechanoluminescence of Coloured Alkali Halide Crystals”. It is one of the longest Chapters in this volume and focusses on both Theoretical and Experimental aspects of elastico-mechanoluminescence (EML), plastico-mechanoluminescence (PML) and fracto- mechanoluminescence (FML) of coloured alkali halide crystals in all details.Chapters 6 & 7 are contributed by an upcoming Group working under Dr Sanjay Dhoble of RTM university Nagpur. The authors investigate PL and TL properties of Eu2+ and Ce3+ Activated BaAlSi5O2N7 Phosphors in the 6th Chapter: “Photoluminescence and Thermoluminescence Properties of Eu2+ and Ce3+ Activated BaAlSi5O2N7 Phosphors”. TL dose response of BaAlSi6O2N7:Eu2+ Phosphor was found to be linear in the dose range from 5.8 mGy to 22.5 mGy, and above this, it goes to the saturation level. 7th chapter: “Photoluminescence Properties of YAl3(BO3)4:RE3+ (RE=Ce/Dy/Tb) Phosphors” is also focused on PL properties of phosphors. It was found that this phosphor acts as a potential color tunable UV phosphor for white light LED devices.Chapters 8 & 9 are contributed by Meera Ramrakhiani Group of RD University, Jabalpur. EL studies have been made by this group of young researchers in their contributed Papers: “Electroluminescence in Organically Capped Cd1-x ZnxSe Chalcogenide Nanocrystals” and “Synthesis and Electroluminescence of Silver Doped ZnS/PVK Nanocomposite”, respectively. It is interesting to note that research work on Nanocomposites has been recognized to boost the economy at global level. Effect of Silver doping and ZnS loading has been investigated on the performance of ZnS/PVK nanocomposite in the last Chapter of this Volume.

Description: The point defect is just one of the menagerie of defects (comprising dislocations, disvections, discommensurations, stacking-faults, antiphase boundaries, etc.) which affect the mechanical and other properties of all materials. The class of point defect can be further divided into interstitial, substitutional and antisite. Various combinations of these defects lead to pairings such as those of Frenkel and Shottky type. The present volume comprises a compilation of selected data concerning point defects in metals, semiconductors, carbon and carbides, nitrides, halides, oxides and miscellaneous materials including solid inert gases. Not mentioned here are Stone-Wales defects, which were covered in volume 356. The 458 entries of the present volume cover the period from 1962 to 2014.
