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.

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
