A fiber assembly according to the present disclosure includes a fiber, and a coating layer that contains an oxide or a nitride covering a surface of the fiber, in which a carbon content in a surface layer of the coating layer is greater than a carbon content inside the coating layer, the fiber assembly is formed by intertwining of the fiber, and the inside or the surface layer of the coating layer contains a hydrocarbon group.

A nanoparticle coater includes a housing; a nanoparticle discharge slot; a first combustion slot; and a second combustion slot.

A method of making a reflective coated glass article includes providing a glass substrate. A first gaseous mixture is formed. The first gaseous mixture includes a silane compound and inert gas. The first gaseous mixture is delivered to a location above a major surface of the glass substrate to deposit a first coating layer directly on the major surface of the glass substrate. The first coating layer is deposited at a thickness of 5-50 nm. A second gaseous mixture is formed. The second gaseous mixture includes a silane compound, a radical scavenger and molecular oxygen. The second gaseous mixture is delivered to a location above the first coating layer. A second coating layer is deposited at a thickness of 5-50 nm over the first coating layer. The coated glass article exhibits a total visible light reflectance (Illuminant D65, ten degree observer) of 45% or more from a coated side of the coated glass article.
