• Sommario/riassunto: "The recent introduction of the nano dimension to pyrotechnics has made it possible to develop a new family of highly reactive substances: nanothermites. These have a chemical composition that is comparable to that of thermites at submillimeter or micrometric granulometry, but with a morphology having a much increased degree of homogeneity. Their reactivity can be specifically defined by playing with the numerous parameters offered by nanomaterial engineering (particle size, degree of homogenization of reactive phases, addition of gas generating agents, etc.), which opens up immense prospects for applications in the pyrotechnic systems of the future. This book discusses the methods of preparation of these energetic nanomaterials, their specific properties, and the different safety aspects inherent in their manipulation."
