Microbiologically Influenced Corrosion : An Engineering Insight
Microbiologically-influenced corrosion (MIC) is one of the greatest mysteries of corrosion science and engineering, due to the complexities resulting from the involvement of living things such as bacteria. Bacteria are not only able to affect our health, but are also capable of impacting upon everyday life through a wide range of industrial sectors and the economy. Microbiologically Influenced Corrosion: An Engineering Insight introduces a new approach to the basics of MIC and explains how to recognise, understand, mitigate and/or prevent this type of corrosion. Topics explored include stress corrosion cracking and microbial corrosion, the pros and cons of biocides, the involvement of magnetic bacteria in microbial corrosion, and a new interpretation of cathodic protection based on recent research in microbial environments.
Interface Oral Health Science 2007 ; Proceedings of the 2nd International Symposium for Interface Oral Health Science, Held in Sendai, Japan, Between 18 and 19 February, 2007
Interface Oral Health Science is a major theme for next-generation dental research. That theme is based on the innovative concept that healthy oral function is provided by biological and biomechanical harmony among three systems: oral tissues including the teeth, mucosa, bones, and muscles (host); parasitic microorganisms of the oral cavity (parasites); and biomaterials. The concept posits that oral diseases such as dental caries, periodontal disease, and tempo- mandibular disorders should be interpreted as interface diseases that result from disruption of the intact interfaces among these systems. The uniqueness of this concept rests on the fact that it not only encompasses the entire fi eld of dentistry and dental care, but also expands the common ground shared with many other fields, including medicine, pharmaceutical science, agriculture, material science, and engineering.
Hot cracking phenomena in welds
The first chapter provides an overview of the various hot cracking phenomena. Different mechanisms of solidification cracking proposed in the past decades are summarized and new insight is particularly given into the mechanism of ductility dip cracking. The effects of different alloying elements on the hot cracking resistance of various materials are shown in the second chapter and, as a special metallurgical effect, the initiation of stress corrosion cracking at hot cracks has been highlighted. The third chapter outlines how numerical analyses and other modelling techniques can be utilized to describe hot cracking phenomena and how such results might contribute to the explanation of the mechanisms. Various hot cracking test procedures are presented in the final chapter with a special emphasis on standardization. For the engineering and natural scientists in research and development the book provides both, new insight and a comprehensive overview of hot cracking phenomena in welds. The contributions additionally give numerous individual solutions and helpful advice for international welding engineers to avoid hot cracking in practice. Furthermore, it represents a very helpful tool for upper level metallurgical and mechanical engineering students.

Characterization of Corrosion Products on Steel Surfaces
It is well known that corrosion products, i.e. rust, on iron and steel surfaces cannot be assigned a typical crystallographic structure with long-range order. In fact, the structure of rust is considered to be very complicated, and some forms of rust are assigned to the amorphous state for this reason. Accurate information about the atomic-scale structure of rust is important to shed light on corrosion mechanisms of metallic materials. And, since life of steel structures is often dominated by environmental degradation or corrosion of the surface, the structure of the rust formed on iron and steel surfaces during prolonged exposure to air is of great interest. This book describes the fundamental aspects of materials characterization for the ferric oxyhydroxides formed on steel surfaces.
