Porous ceramics have recently gained growing importance in industry because of their many applications like filters, absorbers, dust collectors, thermal insulation, hot gas collectors, dielectric resonators, bioreactors, bone replacement and automobile engine components. Generally, porous ceramics have good properties such as mechanical strength, abrasion resistance, and chemical and thermal stability. These porous network ceramic structures also have relatively low density, low mass and low thermal conductivity. Furthermore, permeability is one of the most important properties of porous ceramics for different applications such as membranes because this property directly relates to the pressure drop during filtration. Pore size control is one key factor in fabrication of porous ceramics. The size of particles and their distribution of the raw materials, manufacturing techniques, types of binder used, distribution of binder, and sintering affect the final porosity and pore connectivity, are important things that must be considered during the manufacturing of a porous ceramic body. Therefore, the development of porous ceramic research requires sufficient mechanical and chemical stability as well as permeability. This book covers a wide range of topics such as porous ceramic structure and properties, preparation, simulation and fabrication, sintering, applications for bioceramics, sensors, magnetics and energy saving.

CMP and polishing are the most precise processes used to finish the surfaces of mechanical and electronic or semiconductor components. Advances in CMP/Polishing Technologies for Manufacture of Electronic Devices presents the latest developments and technological innovations in the field - making cutting-edge R&D accessible to the wider engineering community. Most of the applications of these processes are kept as confidential as possible (proprietary information), and specific details are not seen in professional or technical journals and magazines. This book makes these processes and applications accessible to a wider industrial and academic audience. Building on the fundamentals of tribology - the science of friction, wear and lubrication - the authors explore the practical applications of CMP and polishing across various market sectors. Due to the high pace of development of the electronics and semiconductors industry, many of the presented processes and applications come from these industries. Demystifies scientific developments and technological innovations, opening them up for new applications and process improvements in the semiconductor industry and other areas of precision engineering Explores stock removal mechanisms in CMP and polishing, and the challenges involved in predicting the outcomes of abrasive processes in high-precision environments The authors bring together the latest innovations and research from the USA and Japan

Porous Semiconductors: Optical Properties and Applications provides an examination of porous semiconductor materials. Beginning with a description of the basic electrochemistry of porous semiconductors and the different kinds of porous semiconductor materials that can be fabricated, the book moves on to describe the fabrication processes used in the production of porous semiconductor optical components. Concluding the text, a number of optical components based on porous semiconductor materials are discussed in depth. Porous Semiconductors: Optical Properties and Applications provides a thorough grounding in the design, fabrication and theory behind the optical applications of porous semiconductor materials for graduate and undergraduate students interested in optics, photonics, MEMS, and material science. The book is also a valuable reference for scientists, researchers, and engineers in the field of optics and materials science.

The symposium entitled "New Developments in Porous Silicon. Relation with Other Nanostructured Porous Materials" took place in Strasbourg on 4-7 June 1996 hosted by the EMRS Society. Its objectives were to assess the recent developments in porous silicon research and make the 'porous Si community' more aware of related porous materials. The 71 papers contained in these proceedings account for about 80% of the work presented at the meeting and cover nine different topic areas. Chapter 1 focuses on some recent advances in porous Si fabrication and a new formation mechanism involving specific point defects, extensions to the basic anodization process for preparing macropore arrays, multilayers as well as both thin and thick high porosity layers and the realisation of luminescent porous structures from device quality &agr;-Si:H material. Controlled chemical modification of the internal surface of porous Si, an important emerging technique for both stabilising, understanding and introducing new functionality into the properties of the material is discussed in chapter 2 along with the new and exciting developments taking place in the nanocomposites area. The papers in chapter 3 discuss photochemical effects, properties of 'wet' and 'dry' porous Si layers and new approaches to characterising 'wet' material along with an important highlight of the symposium - blue emission in oxide-free layers. Chapter 4 covers many new developments and the refining of existing techniques regarding characterising porous Si and chapter 5 reviews the luminescent silicon nanostructures that have been fabricated other than anodization. The presentation of various porous materials and overviews on the fabrication characterisation and applications of porous alumina are covered in chapter 6, and chapter 7 focuses on the growing interest in porous Si multilayer structures and the potential for realising practical SiLEDs with chapter 8 covering the work that has been presented in this field. New applications for porous Si materials which has an enormous world-wide interest is discussed in the final chapter of the proceedings.
