Defects and diffusion are key concepts at the description of nuclear materials behavior at thermal and radiation impacts. The evolution of various defects (such as point defects, dislocations, grain boundaries) determines changes of the materials properties under operating conditions. The present issue contains new and relevant data about the diffusion and defects in nuclear fuel (uranium alloys, oxide and nitride fuel) and structural materials (steel and non-ferrous metals). We hope that this special issue will be useful for researchers and engineers working in the field of material science and nuclear engineering. We wish to thank the authors for their contributions to this special issue and reviewers for their cooperation and efforts to prepare and evaluate the manuscripts.

Description: Volume is indexed by Thomson Reuters CPCI-S (WoS).
The main focus of this collection of peer-reviewed articles is three different aspects of biohydrometallurgy: this is the field of microbial ecology which is the key to answering central questions concerning not only the diversity and behavior of micro-organisms in commercial operations, but also possible applications in biohydrometallurgy of extremophiles coming from very different environments. This covers metal recovery bioprocesses, including basic and applied studies of bioleaching and bio-oxidation; but also bioflotation. A large part of the book is given over to interfacial studies which contribute to the understanding of the interaction between surfaces and micro-organisms during those processes. Also covered are the remediation of mining activities and environmental protection as related to mining and mining industries.
