A method for producing a layer for coating the inner surface of a container and a glass or plastic container obtained by said method, wherein said container is suitable for containing products biocompatible with humans and/or animals. The method includes: forming a solution containing a solvent, water, a molecular precursor comprising alkoxy groups and an acid as a catalyst, mixing said solution to initiate hydrolysis and condensation, applying the resulting solution onto at least one portion of the inner surface of the container, while the solution is in the process of gelling, the resulting applied solution is then dried at a temperature for a predetermined time, before curing. The acid is citric acid, wherein said citric acid is at a concentration of less than 6 mol/l, and in that the solution comprises less than 1.5 units of precursor for each volume unit of acid.

Embodiments described herein provide for optical devices with methods of forming optical device substrates having at least one area of increased refractive index or scratch resistance. One method includes disposing an etch material on a discrete area of an optical device substrate or an optical device layer, disposing a diffusion material in the discrete area, and removing excess diffusion material to form an optical material in the optical device substrate or the optical device layer having a refractive index greater than or equal to 2.0 or a hardness greater than or equal to 5.5 Mohs.

Durable and optically transparent superhydrophobic surfaces have a coating of ceramic nanoparticles attached to a transparent substrate that are bound to the substrate through a flexible linker and a fluorocarbon moiety is bound to the surface of the ceramic nanoparticles. The nanoparticles provide the topography required for superhydrophobic surfaces and the fluorocarbon attached to the surface renders the particles hydrophobic. The nanoparticles can be metal oxide nanoparticles of dimensions that do not scatter light and the flexible linker can be constructed by an agent that has a group for bonding to the substrate and a reactive group to form a bond with a complementary second reactive group attached to a second agent that has a group for bonding to the nanoparticles.
