Interfacial materials overview

The symposium on which this book is based was organized to provide a forum for discussion of recent advances in the use of polymeric materials in corrosion control. Most of the papers presented in the symposium are included in this volume. Several chapters have been added. These include an introductory overview as well as separate review chapters on how organic coating systems protect against corrosion, on mechanisms of adhesion loss of organic coatings, and on the interfacial chemistry of adhesion loss in aggressive environments. 

The purpose of this paper is to provide a broad overview of why interfacial stability is crucially important in materials used for the direct conversion of solar radiation to useful end-products in man-made col-lection/conversion systems. The importance of interfacial stability and studies of interfacial phenomena has been addressed in considerable detail in previous review articles (1-3) and in the proceedings of a workshop (4). 

In the following paragraphs an overview of damage due to thermal shock and its effect on the mechanical properties of CMCs with different fibre architectures is provided for a number of different reinforcement architectures. Subsequently, the effect of thermal shock on interfacial properties is discussed, followed by a description of attempts to analyse and model the thermal shock behaviour of these materials. 

In conclusion, this book is intended as an overview of the principles behind and state-of-the-art in interfacial supramolecular chemistry. The book is suitable for researchers and graduate students and focuses on assemblies that demonstrate at least the potential to produce useful devices such as solar cells, electrochromic devices, molecular wires, switches and sensors which are addressable by using electrochemical and optical stimuli. Molecular materials for nanoscale molecular devices remain an intriguing conceptual possibility.

Professor Doron Aurbach of Bar-Ilan University, Israel, contribute Chap. 6, which provides a review of the surface chemistry of cathode materials including transition metal spinel, transition metal layer, transition metal phosphate, and oxygen cathode materials in nonaqueous electrolytes. Dr. Jordi Cabana of Lawrence Berkeley National Laboratory wrote Chap. 7, which provides an overview of the experimental tools and the kind of information they can offer with representative examples in the literature. It is important to recognize that no single technique can currently provide the answers to these complex interfacial phenomena in Li and Li-ion batteries. 

Interfacial phenomena play an essential role in many biomedical applications. The reaction of the body towards implants largely depends on the surface properties of the latter. The corrosion or the degradation of materials placed in contact with biological fluids is initiated at the material-fluid interface. The successful design of biosensors or of supports for cell culture relies on the tqtpropriate modification of a material surface and on the interaction of that modified surface with macromolecules in solution or with cells. An overview of key constituents and processes that are... 

One way of providing an overview of much of the foregoing material is to consider measurements of displacements near a crack front. It will also provide some points to ponder. A method that the author has used successfully is crack opening interferometry. This requires that at least one of the components of the bonded joint under consideration is transparent to the wavelength of the radiation being used. At first, especially considering the visible spectrum, this may seem to be rather restrictive. However, infrared opens up many practical microelectronics applications due to silicon s transparency to it. The technique also requires that the crack surfaces be quite planar. This condition is not always met by eraeks in monolithic materials, but interfacial or sub-interfacial cracks often meet the planarity requirements. 

The main objective of this chapter is to describe the state of the art in solid oxide fuel cells (SOFC), with an emphasis on materials (electrolytes, electrodes, intercoimects), interfacial reactions, and cell configurations. Several overviews have already been published on the subject and provide relevant backgroimd information. - ... 

Abstract Multicomponent materials based on synthetic polymers were designed and used in a wide variety of common and hi-tech applications, including the outdoor applications as well. Therefore, their response to the UV radiation and complex weathering conditions (temperature, seasonal or freeze—thaw cycles, humidity, pH, pollutants, ozone, microorganisms) is a matter of utmost importance in terms of operational reliability and lifetime, protection of the environment and health safety. This chapter offers an overview of this subject and a critical assessment of more particular topics related to this issue. Thus, various types of multicomponent systems based on thermoplastic and thermosetting polymer matrices were subjected to natural and/or simulated UV radiation and/or weathering conditions. Their behavior was evaluated in correlation with their complex formulation and taking into consideration that the overall effect is a sum of the individual responses and interactions between components. The nature and type of the matrix, the nature, type and size distribution of the filler, the formation of the interphase and its characteristics, the interfacial adhesion and specific interfacial interactions, they all were considered as factors that influenced the materials behavior, and, at the same time, were used as classification criteria for this review.
