The process includes providing a substrate having a surface, forming a gaseous mixture comprising a non-halogenated source of a metal and a source of magnesium, delivering the gaseous mixture to the surface of the substrate, and depositing the layer based on a metal oxide doped with magnesium or a mixed metal oxide containing magnesium on the surface of the substrate.

A method for preparing an amorphous metal oxide film is provided. The method comprises providing an aqueous composition comprising a metal fluorine compound; and contacting a substrate with the aqueous composition at a temperature of less than about 100° C. to obtain said amorphous metal oxide film on the substrate. An amorphous metal oxide film, and use of the amorphous metal oxide film in various applications are also provided.

The subject of the invention is a material comprising a glass sheet coated on at least one portion of one of the faces thereof with a stack of thin layers comprising at least one layer based on a nitride, said stack being coated on at least one portion of its surface with an enamel layer comprising bismuth, said stack further comprising, in contact with the enamel layer, a layer, referred to as a contact layer, which is based on an oxide.

A process for the preparation of an antimicrobial coating solution is described. The process comprises the steps of: (i) mixing a chelating agent with titanium alkoxide and fluoroacetic acid; and (ii) adding an aqueous solution to the mixture from step (i). The antimicrobial coating described is visible light activated. The coating is applied to surfaces and then heat treated to form a transparent layer on the surface. This is particularly advantageous where the surface is glass.

A controllable privacy structure, such as a window or door, may include an electrically controllable optically active material connected to a driver. The driver can control the application and/or removal of electrical energy to the optically active material to transition from a scattering state in which visibility through the structure is inhibited to a transparent state in which visibility through the structure is comparatively clear. The driver may need to be located in relatively close physical proximity to the privacy structure the driver is intended to control. Devices, systems, and techniques are described for discretely positioning a driver relative to a privacy structure to be controlled.

A coated glass article includes a glass substrate and an anti-reflective coating formed over a first major surface of the glass substrate. The anti-reflective coating includes a color suppression interlayer and a first coating layer deposited over the color suppression interlayer. The first coating layer includes tin oxide and a dopant. The dopant includes antimony, molybdenum, or iron. A second coating layer is deposited over the first coating layer. The second coating layer includes an oxide of silicon. The coated glass article exhibits a total visible light transmittance of 70% or more and a film side visible light reflectance of less than 6.0%.

A privacy glazing structure may include an electrically controllable optically active material, such as a liquid crystal material, sandwiched between a flexible substrate and a rigid substrate. The flexible substrate and the rigid substrate may each have a conductive layer deposited on the surface facing the optically active material. The flexible substrate may be bonded about its perimeter to the rigid substrate and may be sufficiently flexible to conform to non-planarity of the rigid substrate. As a result, the flexible substrate may adopt the surface contour of the rigid substrate to maintain a uniform thickness of optically active material between the flexible substrate and the rigid substrate.
