Abstract: A process of depositing a hydrophobic or superhydrophobic film on a surface of a substrate, effected by spraying onto the substrate's surface a solution comprising a fatty acid and an organic solvent, is provided. Substrates and articles-of-manufacturing containing the substrates, having a hydrophobic or superhydrophobic coating/film deposited thereon, obtainable or prepared by the process, are also provided. The process is usable for reducing a load of a pathogenic microorganism and/or for preventing biofilm formation on and/or in the substrates or articles-of-manufacturing containing same.

Abstract: The present invention relates to a paste comprising amorphous calcium carbonate (ACC) doped with divalent alkaline-earth metal ions, e.g., magnesium ions, or transition metal ions: a dry three-dimensional model made of such a paste, e.g., by 3D-printing process such as robocasting 3D-printing process; and a process for the preparation of said paste.

Abstract: Disclosed is a ceramic composition comprising a plurality of at least semi-coherent particles with an average diameter ranging from 1 nm to 50 nm included within a matrix, wherein the matrix comprises one metal carbonate salt, metal oxide or metalloid oxide, the particles and the matrix share at least one metal element and the metal element is 10% to 80% of the total content of said matrix, and the composition has a lattice mismatch of less than 5%. Disclosed are also an article and methods for making the ceramic composition of the present invention.
