    摘要: The invention describes a nanocomposite particle comprising a nanoparticle having a surface comprising a silver salt, and at least one region of metallic gold on said surface. The invention also provides a nanocomposite material comprising said particles and processes for making the nanocomposite material, either by allowing gold in nanoparticles having a silver salt on the surface thereof to at least partially diffuse through the silver salt so as to form at least one region of metallic gold on said surface, or else by depositing metallic gold on the surfaces of nanoparticles having the silver salt on the surface thereof.

    摘要: A process for making a gel comprising combining a silanol species comprising at least two silanol groups per molecule and a hydrophilic hydroxyl species comprising at least two hydroxyl groups per molecule. The gel is capable of being converted to a liquid by application of a mechanical shear force and the liquid is capable of being converted to the gel in the absence of the mechanical shear force.
