New methods for preparing nanostructures are yielding innovative applications. Pal (Institute of Physics, Autonomous University of Puebla, Mexico) compiles peer-reviewed articles on the synthesis and application of nanomaterials, highlighting recent research trends in Mexico. The articles cover the synthesis of nanoparticles (metals, semiconductors, and ceramics), nanocomposites, and other novel nanostructures, and their applications. Some specific areas explored include proton charge transport in nafion nanochannels, optical properties of non-periodic dielectric systems made of nanostructured porous silicon, Fourier electron density maps for nanostructured sol-gel solids, and the effects of morphology on the electronic properties of hydrogenated silicon carbide nanowires. Papers are illustrated with b&w images.
