The present invention relates to a method of bonding a gold surface to a second surface which comprises heating a hybrid organic-inorganic melting gel &#x3e;50&#xb0; C., applying the melting gel to either the gold surface or the second surface. The melting gel is heated to above 130&#xb0; C. until the melting gel has cured sufficiently to bond the surfaces together. The invention also relates to a combination of a gold surface and a second surface that is bonded together with a hybrid organic-inorganic melting gel. In another aspect of the invention the hybrid organic-inorganic melting gel is heated to a workable viscosity and cast into a film, sheet, block or lens. The cast gel is cured or partially cured and then applied between the gold surface and the second surface. Additional uncured melting gel may be applied. The construct is heated to above 130&#xb0; C. until the melting gel has cured sufficient to bond the surfaces together.

Method of bonding to gold surface and resultant combinations

The invention relates to a process and apparatus for forming a particulate composition, especially a particle glass composition, through the use of shock waves. A nozzle element is utilized having inlets for introduction of cold and heated gas and a delivery tube for introducing molten material. Through the introduction of the cold and heated gases, droplets are formed from a molten stream, a cone-shaped standing shock wave is formed, and shock waves are formed via a modified Hartmann-Sprenger chamber, the shock waves impinging on the droplet stream to break up the larger droplets.
