Fundamental principles of nanocomposites are discussed. The basic features of nanocomposites are low dimensionality of their composition components, widespreadness of the electronic interactions between the components and the great variety of microstructure of nanocomposites ranging from high level ordered 3-dimensional periodic structure to stochastically dispersed medium of superfine particle. All these offer much more potential for tailoring the property of materials than by formation of chemical compound or mixture including microcomposites. Vapour deposition enhanced by ion beam and electrical discharge plasma provides a class of versatile processes both for preparing low dimensional components of nanocomposites and for synthesizing nanocomposite film itself. Elements of designing nanocomposite thin films and their preparing by ion beam and plasma enhanced vapour deposition are also discussed. Examples of nanocomposite films are given.read more

TL;DR: In this paper, it was observed that polycrystalline ceramics became ductile permitting large (~100%) plastic deformations at low temperature if a polycrystaline ceramic was generated with a crystal size of a few nm.

Far-Infrared Absorption in Ultrafine Al Particles
TL;DR: The first far-infrared measurements on metallic particles with diameters 10 nm were reported in this article, where the authors compared the results with the Gor'kov-Eliashberg (GE) theory of particles with quantized electronic levels as well as with the classical Drude theory.
