Antireflective nanoparticle coatings and methods of forming the coatings on substrates are disclosed. One method for forming an antireflective coating includes depositing a nanoparticle coating layer on a substrate, wherein the nanoparticle coating layer includes a colloidal solution of nanoparticles and a solidifying material. The solidifying material includes a silica precursor. The method further includes curing the solidifying material to form silica inter-particle connections between adjacent nanoparticles and between at least some of the nanoparticles and the substrate to bind the nanoparticles to each other and to the substrate to form the antireflective coating.

A laminated glass article includes a core layer and a clad layer directly adjacent to the core layer. The core layer is formed from a core glass composition. The clad layer is formed from a clad glass composition. An average clad coefficient of thermal expansion (CTE) is less than an average core CTE such that the clad layer is in compression and the core layer is in tension. A compressive stress of the clad layer decreases with increasing distance from an outer surface of the clad layer within an outer portion of the clad layer and remains substantially constant with increasing distance from the outer surface of the clad layer within an intermediate portion of the clad layer disposed between the outer portion and the core layer. A thickness of the intermediate portion of the clad layer is at least about 82% of a thickness of the clad layer,

A method of forming a sealed device comprising providing a first substrate having a first surface, providing a second substrate adjacent the first substrate, and forming a weld between an interface of the first substrate and the adjacent second substrate, wherein the weld is characterized by ((σ.sub.tensile stress location)/(σ.sub.interface laser weld))<<1 or <1 and σ.sub.interface laser weld>10 MPa or >1 MPa where σ.sub.tensile stress location is the stress present in the first substrate and σ.sub.interface laser weld is the stress present at the interface. This method may be used to manufacture a variety of different sealed packages.

A coated insulation material comprising an insulation material substrate and a coating on at least part of a surface of the insulation material substrate and wherein the coating comprises 20 to 65 wt % alkali silicate based on the total weight of the cured coating and the alkali silicate comprises potassium silicate. Also described is an aqueous coating composition useful in providing the insulation material coating, a potassium silicate coating, methods of producing the coated insulation material and potassium silicate coating and kit of parts including an insulation material substrate and either the aqueous coating composition or the potassium silicate coating.

A microfabrication method is provided with which it is possible to easily form a fine periodic structure on a surface of any substrate. A glass precursor is applied to a substrate, and the glass precursor is irradiated with short-pulse laser light. By the irradiation with short-pulse laser light, the glass precursor is activated to undergo a thermal reaction, and a fine periodic structure can be easily formed on the surface. Furthermore, by oxidizing the substrate on which the fine periodic structure has been formed, the hue of the surface can be improved while maintaining the fine periodic structure.
