Preface

The invention of the scanning tunneling microscope in 1981, the development of atomic force microscopy in 1984, and the discovery of fullerenes in 1985 are three major events that defined the birth of nanotechnology. These three events triggered a series of new explorations and applications of micro- and nanostructured materials, which have modified and different phys‐ ical and chemical properties compared to the same elements at larger scales. It is for this reason that the precise control of individual components in nanostructures is crucial to realizing dif‐ ferent functionalities in applications in electronics, energy-conversion devices, biotechnolo‐ gies, and other specific applications. The morphology of the nanostructures depends not only on the compatibility between their component phases but also on the mixing method and its dispersion if chemical approaches are used. On the other hand, the use of physical methods, self-assembly, and bottom-up approaches also allows bulk nanostructures to be synthesized. The micro- and macroscopic properties of the system (optical or magnetic properties, conduc‐ tivity, etc.) can vary without changing the chemical composition of the original material simply

In this book, the reader will discover the manufacture of nanostructures with current meth‐ odologies and their applications and uses in different techniques applied to engineering. These aspects make the application and development of new composites attractive in differ‐ ent technologic fields, improving performance parameters in equipment with respect to en‐ ergy savings. In addition, new and improved technological applications are being
