A method includes depositing a surface modification layer on sidewalls of a plurality of cavities of a shaped article. The surface modification layer is formed from a glass material including a mobile component. The shaped article is formed from a glass material, a glass ceramic material, or a combination thereof. At least a portion of the mobile component is migrated from the surface modification layer into surface regions of the sidewalls of the shaped article, whereby subsequent to the migration, the surface regions have a reduced annealing point compared to a bulk of the shaped article. The surface modification layer and the surface regions of the sidewalls are reflowed. A surface roughness of the surface modification layer disposed on the sidewalls following the reflowing is less than a surface roughness of the sidewalls prior to the depositing.

Apparatuses and methods for glass laminates having a controlled coefficient of thermal expansion are disclosed. In C one embodiment, a glass laminate includes a glass core having a core thickness (T) and a core coefficient of thermal expansion (CTE), a first glass cladding layer and a second glass cladding layer. The first glass cladding layer and the second glass cladding layer are arranged such that the glass core is disposed between the first glass cladding layer and the second glass cladding layer. The first glass cladding layer has a first cladding thickness (T) and a first clad coefficient of thermal expansion (CTE), and the second glass cladding layer has a second cladding thickness (T) and a second clad coefficient of thermal expansion (CTE). The glass laminate has a laminate coefficient of thermal expansion (CTE) within a range of about 35&#xd7;10/&#xb0; C. to about 90&#xd7;10/&#xb0; C., the laminate coefficient of thermal expansion (CTE) defined by: CTE=((CTE&#xd7;T)+(CTE&#xd7;T)+(CTE&#xd7; T))/(T+T+T).

Described herein are improved dewetting methods and improved patterned articles produced using such methods. The improved methods and articles generally implement continuous ultra-thin metal-containing films or film stacks as the materials to be dewetted. For example, a method can involve the steps of providing a substrate that has a continuous ultra-thin metal-containing film or film stack disposed on a surface thereof, and dewetting at least a portion of the continuous ultra-thin metal-containing film or film stack to produce a plurality of discrete metal-containing dewetted islands on the surface of the substrate.

Laminated articles and layered articles, for example, low alkali glass laminated articles and layered articles useful for, for example, electrochromic devices are described.

A burner manifold apparatus ( ) for delivering reactants to a combustion site of a chemical vapor deposition process includes fluid inlets ( ), fluid outlets ( ), and a plurality of fluid passages ( ) extending therebetween. The fluid passages ( ) converge toward each other from the fluid inlets to the fluid outlets. One embodiment includes a manifold base ( ), a pressure plate ( ), and a manifold burner mount ( ) for mounting thereto a micromachined burner ( ). The fluid passages ( ) internal to the manifold base are configured to distribute symmetrically the fluid to the manifold burner mount. The fluid is then channeled through fluid passages in the manifold burner mount. The fluid passages converge, yet remain fluidly isolated from each other, and the fluid passages create a linear array for producing linear streams of fluid. Alternatively, the burner manifold apparatus may include a plurality of manifold elements in a stacked arrangement. In this alternative embodiment, the manifold elements are configured to produce a linear array of fluid passages at the top of the stack, increasing the number of fluid passages at each level of the stack closer to the top. As yet a further alternative, the burner manifold may be produced by extruding a particulate composite through a die to produce a manifold having fluid passages therein. This extruded manifold generally has a tapered section to which a burner may be mounted.

Burner manifold apparatus for use in a chemical vapor deposition process

A cutting fluid applicable for the machining of vitreous, crystalline or aggregate materials such as glass, glass-ceramics, ceramics, stone, concrete, silicon and the like. The cutting fluid comprises a solution containing organic molecules&mdash;in particular silanes, silanols, and siloxanes&mdash;capable of forming covalent bonds with such vitreous, crystalline or aggregate materials. The organic molecules in the cutting fluid is believed to improve the rate of manufacturing productivity, surface finish quality, and decrease the incidence of sub-surface damage caused by particulate adhesion to the cutting or abrading tool during a machining process of these kinds of substrates. The reduced clogging of cutting surfaces and increased lubricity of the cutting fluid may also prolong the useful life of the machining tools when used against these kinds of substrates.

A reflective polarzier for visible light wavelengths formed of a plurality of polarizer units. Each polarizer unit having a transparent, inorganic substrate with first and second opposing surfaces. The first surface is coated with a single layer of a dielectric material, and the second surface is coated with a layer of a highly reflective metal film or a dielectric material. The polarizer is configured to produce a &ldquo;quasi-straight path,&rdquo; such that a light ray exiting the substrate is substantially parallel with a corresponding, incident light ray entering the substrate. The polarizer exhibits polarization over the entire visible spectrum.

A method for making silicon oxynitride comprising providing a vaporous gas stream of a compound selected from the group consisting of silazanes and siloxazanes. An enclosed, heated reaction site is also provided. The vaporous gas stream is delivered to the enclosed, heated reaction site in which the levels of oxygen are strictly controlled to promote the formation of silicon oxynitride particles.

An athermalization attachment for countering changes in optical characteristics of an optical fiber or other temperature sensitive optical device in response to changes in temperature. According to one aspect of the invention, a curved composite beam is attached to the fiber. The beam comprises two layers of dissimilar materials. The layer on the outside radius has a coefficient of expansion greater than that of the layer on the inside radius, such that increases in temperature cause the outside layer to expand more rapidly than the inside layer, thereby decreasing the radius of curvature of the beam. The coefficients of expansion of the layers are chosen such that the beam's temperature response counters optical changes which would otherwise occur in the fiber in response to temperature changes. In another approach, one point on a low-expansion block is attached to a point along an optical fiber. A high-expansion bar is attached to another point along the fiber, and positioned with respect to the fiber and the low-expansion block such that expansion of the high-expansion bar compensates for the temperature response of the fiber. A variety of additional geometries are disclosed.
