"Structural nanomaterials are distinguished by unusually high strength, hardness, and wear resistance as well as good fatigue resistance, fracture toughness, and extensive high-temperature formability. As materials scientists devise new techniques to measure and model important mechanical and physical properties as a function of these length scales down to the atomistic level, materials engineers are developing methods to exploit size dependencies to design and optimize materials.
Structural Nanomaterials will feature a wide range of topics representing such progress, including experimental nanomechanics, stability of nanomaterials, bionanomaterials, nanoprecipitate engineering, nanostructure in advanced alloys and high entropy alloys, contact and wear in nanomaterials, surface stresses and strains, and mechanical effects on functional properties.
Nanomaterials with different crystal structures may differ in important physicochemical properties (e.g. reactivity or photocatalytic activity). Accordingly, in such cases only a specific crystal structure is used for a given application. The different crystal structures are not only relevant for the various technical applications, but can also affect the behavior and toxicity of nanomaterials.
An example for such a material is titanium dioxide (TiO2). To sun screen or as white pigment in paints it is mainly added in the rutile form, whereas for photocatalytic applications (such as self-cleaning surfaces) predominantly the anatase form is used.
The various crystal structures of nanomaterials have to be taken into account when analyzing potential adverse effects on organisms or the environmental behavior. The physico-chemical properties of the materials are known to differ depending on crystal structure.
This book has been written in easy and fluent language expressive and self-explanatory labelled diagrams, concise but not too brief, written to the point starting from fundamentals and finishing to the most advanced and current concepts. All diagrams have been provided with detailed legends. Some diagrams have been drawn the author himself from the original source, while the remaining ones are quoted from the authentic works."
