Cover: The picture depicts the mechanism of peroxide‐assisted coupling of isotatic poly(propylene) (iPP) and carbon nanofibers (CNFs), which, in turn, leads to improved adhesion between the filler (CNF) and the polymeric matrix (iPP) and increased stiffness of the matrix. Further details can be found in the article by A. de la Vega Oyervides, J. Bonilla Ríos, * L. F. Ramos de Valle, L. A. S. de Almeida Prado, and K. Schulte on page 1095.
