Cover: Nanocomposite coatings mixing hard nanocrystalline phases of TiBC in a soft amorphous carbon matrix are prepared by magnetron sputtering of a composite TiC:TiB2 target and graphite. The electrical resistivity and crystalline structure of the coatings can be varied depending on the carbon content. The formation of two types of boron bonding is reported in a ternary TiBC compound. Further details can be found in the article by M. D. Abad, R. Sanjinés, J. L. Endrino, R. Gago, J. Andersson, and J. C. Sánchez-López* on page 579.
