Book Description
This conference consisted of 15 oral sessions, including three plenary papers covering areas of general interest, 22 specialist invited papers and 51 contributed presentations as well as three poster sessions. There were several scientific highlights covering a diverse spectrum of materials and ion beam processing methods. These included a wide range of conventional and novel applications such as: optical displays and opto-electronics, motor vehicle and tooling parts, coatings tailored for desired properties, studies of fundamental defect properties, the production of novel (often buried) compounds, and treating biomedical materials. The study of nanocrystals produced by ion implantation in a range of host matrices, particularly for opto-electronics applications, was one especially new and exciting development. Despite several decades of study, major progress was reported at the conference in understanding defect evolution in semiconductors and the role of defects in transient impurity diffusion. The use of implantation to tune or isolate optical devices and in forming optically active centres and waveguides in semiconductors, polymers and oxide ceramics was a major focus of several presentations at the conference. The formation of hard coatings by ion assisted deposition or direct implantation was also an area which showed much recent progress. Ion beam techniques had also developed apace, particularly those based on plasma immersion ion implantation or alternative techniques for large area surface treatment. Finally, the use of ion beams for the direct treatment of cancerous tissue was a particularly novel and interesting application of ion beams.

Book Description
The topic of polymer surface modification is of tremendous contemporary interest because of its critical importance in many and varied technological applications where polymers are used. Currently there is brisk research activity in unraveling the mechanisms of surface modification and finding ways to prolong the life of surface treatment. Also there is acute interest and need to devise new, improved and economical means to modify polymer surfaces. This book is divided into three parts as follows: Part 1: Surface Modification Techniques; Part 2: Interfacial Aspects and Adhesion; Part 3: General Papers. The topics covered include: various techniques for surface modification including plasma (both vacuum and atmospheric pressure), ozone, photografting, UV photo-oxidation, laser, use of charged particles and others for a variety of polymers; longevity of surface treatment; hydrophobic recovery; fabrication of high-density polymer nano-dots; immobilization of organometallic catalysts on textile carrier materials; polymer membrane antifouling properties; electroless metallization of polymers; effects of surface modification on interfacial shear strength of composites, cord/rubber adhesion, adhesion of UV-curable coatings and attachment of hyperbranched polymers; plasma polymerization; block copolymers; application of plasma technology in decontamination of heat-sensitive polymer surfaces. In essence this book reflects the current state-of-the-knowledge in the arena and represents the work of many renowned scientists and technologists. It should be of interest to anyone with a desire or need to learn the latest R&D activity in this domain and the information contained here should be very valuable in deciding the optimum surface modification technique for his/her particular requirements.

Book Description
Many books are available that detail the basic principles of the different methods of surface characterization. On the other hand, the scientific literature provides a resource of how individual pieces of research are conducted by particular labo- tories. Between these two extremes the literature is thin but it is here that the present volume comfortably sits. Both the newcomer and the more mature scientist will find in these chapters a wealth of detail as well as advice and general guidance of the principal phenomena relevant to the study of real samples. In the analysis of samples, practical analysts have fairly simple models of how everything works. Superimposed on this ideal world is an understanding of how the parameters of the measurement method, the instrumentation, and the char- teristics of the sample distort this ideal world into something less precise, less controlled, and less understood. The guidance given in these chapters allows the scientist to understand how to obtain the most precise and understood measu- ments that are currently possible and, where there are inevitable problems, to have clear guidance as the extent of the problem and its likely behavior.

Book Description
Plasma processing is a high-technology discipline in tailoring surface properties and in obtaining functional polymers of advanced materials without changing the material's bulk. Comparing with solid polymeric materials, special care should be taken for surface activation of textiles due to their complex geometries. It was found that modification is strongly influenced by both plasma parameters and fabric structure. As compared to air, CO2, and water vapor, Ar/O2 and He/O2 mixtures were found to be very effective for surface hydrophilization of polyester textiles due to the long-lasting free radical lifetimes. The modified surfaces were not stable for a long time due to restructuring of the polar functional groups. Therefore, plasma coatings containing functional groups are required in order to obtain a permanent surface modification. Permanent nanoporous coatings were deposited in order to obtain functional surfaces which contain accessible functionalities within the entire coating volume. This novel approach is essentially based on a fine control of simultaneous deposition and etching processes during plasma co-polymerization of ammonia with hydrocarbons. A nanoporous structure with a large specific surface area was achieved that contained functional groups inside the coating volume, which were accessible to e.g. dye molecules, thus facilitating substrate independent dyeing. A permanent hydrophilic modification of material surfaces was obtained by introducing nitrogen polar functionalities, depending on the NH3 to hydrocarbon ratio, which is mostly due to a replacement of carbon in a-C: H: N films. This novel combination of polar groups with a suitable texturing realized within crosslinked aC: H: N coatings proved to be an efficient method providing a long-term mechanical stability of superhydrophilic coatings. Moreover, plasma coated material surfaces contain huge numbers of functional groups which can chemically interact with matrix materials and hence, yield strong covalent bond between fiber and matrix. The coatings show a large surface area which enhances the contact area and surface texturing and additionally promotes mechanical interlocking. Thus, the novel, developed nanoporous coatings represent a platform for diverse multifunctional applications in the surface enhancement of advanced material
