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.

Catalytic role of amino acids in organic reactions

Asymmetric organometallic and organocatalytic processes have attracted great interest. Asymmetric synthesis using both natural and unnatural amino acids has been tremendously important from synthetic as well as industrial viewpoints, and numerous new methodologies have been developed in the last decades. Herein we provide an overview of old and very recent (since 1900 till now) advances and applications in the area of heterogeneous catalysis, homogeneous catalysis, electrocatalysis, photocatalysis, organocatalysis, thermal catalysis using amino acids [proline, glycine, alanine, valine, serine, threonine, cysteine, methionine, asparagine, glutamine, lysine, arginine, histidine, aspartate, glutamate, phenylalanine, and tryptophan], (supported or unsupported), an amino acid containing materials or amino acids derivatives as an essential component of catalysts, this book highlights the most important and recent developments to immobilize or support amino acids on various support materials. This book is suitable as supplementary reading for courses targeting the design, synthesis, and application of chiral catalysts, asymmetric catalysis, and sustainable production.

Biomining

Biomining is the biotechnology that uses microorganisms to recover metals, in particular copper and gold, from ores and concentrates. Having developed from a very simple operational (in terms of both engineering and biology) process, biomining has developed into a multifaceted technology, to the extent that many of the largest industrial stirred tanks and heaps throughout the world are employed for bioprocessing minerals. This book has a strong applied approach and describes emerging and established industrial processes, as well as the underlying theory of the process, and the biology of the microorganisms involved. Chapters have been written by personnel from leading biomining companies, consultants and internationally recognized researchers and academics
