Nanostructured Coatings
Controlling the performance of structures and components of all sizes and shapes through the use of engineered coatings has long been a key strategy in materials processing and technological design. The ever-increasing sophistication of en- neered coatings and the rapid trend toward producing increasingly smaller devices with greater demands on their fabrication, properties and performance have led to signicant progress in the science and technology of coatings, particularly in the last decade or two. Nanostructured coatings constitute a major area of sci- ti?c exploration and technological pursuit in this development.Nanostructured coatings demand study in a highly interdisciplinary research arena which encompasses: surface and interface science study of defects modern characterization methodologies cutting-edge experimental developments to deposit.

Modern industry imposes ever increasing requirements upon tools and tool materials as to the provision for performance under the conditions of high cutting speeds and dynamic loads as well as under intensive thermal and chemical interactions with workpiece materials. The industry demands a higher productivity in combination with the accuracy of geometry and dimensions of workpieces and quality of working surfaces of the machined pieces. These requirements are best met by the tool superhard materials (diamond and diamond-like cubic boron nitride). Ceramics based on silicon carbide, aluminum and boron oxides as well as on titanium, silicon and aluminum nitrides offer promise as tool materials. Tungsten-containing cemented carbides are still considered as suitable tool materials. Hi- hardness and high strength composites based on the above materials fit all the requirements imposed by machining jobs when manufacturing elements of machinery, in particular those operating under the extreme conditions of high temperatures and loads.
Dynamic Response of Advanced Ceramics
In Dynamic Response of Advanced Ceramics, an accomplished team of internationally renowned researchers delivers a comprehensive exploration of foundational and advanced concepts in experimental, analytical, and computational aspects of the dynamic behavior of advanced structural ceramics and transparent materials. The book discusses new techniques used for determination of dynamic hardness and dynamic fracture toughness, as well as edge-on-impact experiments for imaging evolving damage patterns at high impact velocities.

Bone disorders
• Bone is the specialized type of connective tissue that has extracellular matrix containing calcium salts. • As bone is a connective tissue, it consists of cells and matrix. • Mineralized extracellular matrix provides hardness to bones. • Bone is a living tissue that shows dynamic structural changes in response to physical stress and hormonal changes. • In addition to support and protection of vital organs, bones act as a storehouse for calcium and phosphates. • Bone also performs hematopoietic function (production of blood cells).
