OverviewThis book presents new data on combustion processes for practical applications, discussing fire safety issues in the development of flame arresters and the use of noble metals in hydrogen recombiners for nuclear power plants. It establishes the basic principles of production of metal nanostructures, namely nanopowders of metals and compact products made of them, with the preservation of the unique properties of nanoproducts.
