A method for preparing a microstructure on the surface of glass by titanium oxide nanoparticle-assisted infrared nanosecond laser, including the following steps: (1) dropwise applying a titanium oxide nanoparticle hydrogel onto the surface of a glass sample; (2) pressing another piece of glass on the surface of the hydrogel, so the hydrogel is evenly distributed between the two pieces of glass, and allowing the two pieces of glass to stand horizontally for a period of time to air-dry the hydrogel; (3) separating the two pieces of glass to obtain a glass with a uniform titanium oxide nanoparticle coating; (4) forming a microstructure using an infrared nanosecond laser with a wavelength of 1064 nm; and (5) performing after-treatment, including ultrasonically cleaning the sample with acetone, absolute ethanol and deionized water respectively for 10 min to remove titanium oxide nanoparticles attached to the surface, to obtain a glass sample with the microstructure.

A window structure includes a metal layer that transmits microwave signals and reflects infrared signals. A microwave signal is a signal that has a frequency in the microwave spectrum of frequencies (a.k.a. the microwave frequency spectrum). The microwave frequency spectrum extends from 300 megahertz (MHz) to 300 gigahertz (GHz). An infrared signal is a signal that has a frequency in the infrared spectrum of frequencies (a.k.a. the infrared frequency spectrum, which extends from 300 GHz to 430 terahertz (THz)). The metal layer may be a discontinuous metal layer that's an electrically discontinuous metal layer and/or a physically discontinuous metal layer.

The water container includes an opening configured to receive water, a container body arranged to enclose the water and a water purifying unit configured to purify the water. The water purifying unit includes an at least partially transparent plate, which includes a coating of metal-oxide nanoparticles on a first side facing the container body, wherein the first side is configured to be in contact with the water, and an ultraviolet light module configured to radiate towards a second side of the at least partially transparent plate such that light from the ultraviolet light module at least partially passes through the at least partially transparent plate. Also, a method for purifying water within a water container.

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.

Reflectors comprising thin film dichroic coatings are located on various components of a waveguide-based optical combiner in a see-through display of a head-mounted display (HMD) device to reduce color cross-coupling in holographic images and reflect forward-projected holographic image light back to a user's eye. The dichroic coatings implement narrowband reflectors for each of one or more colors of an RGB (red, green, blue) color model over the angular range associated with the field of view (FOV) of the virtual portion of the see-through display. Utilization of the dichroic coatings can improve virtual display uniformity and lessen sharp edge defects by reducing cross-coupling and may also improve light security by reducing the forward-projected holographic image light that escapes from the HMD device.

The ΔE* value(s) may be measured either with a substantially symmetrical/similar AR coating on the other side of the same glass substrate, or absent any AR coating on the other side of the glass substrate.
