Novel formulations of inorganic, chemically bonded, phosphate alumino silicate sprayable coatings are disclosed. The disclosed coatings retain all the positive attributes of similar coatings disclosed in recent patents on corrosion and fire protection, and in addition, provide, superior surface toughness and smoothness, better abrasion and acid resistance, less erosion and longer durability with zero flame-spread coatings on wood surfaces. Being pore-free, water cannot penetrate into these coatings. Unlike the previous inorganic oxide-based phosphate coatings, the glassy phase in these coatings provides a translucent and dense surface. The component pastes are smoother to pump, do not settle or harden during storage and transport, and in addition, do not exhibit pozzalinic properties.

An energy-saving glass includes a glass substrate, and a periodic metal layer deposited on the glass substrate and having a honeycomb array of round holes.

Aspects of the disclosure relate to preventing unauthorized screen capture activity. A computing platform may detect, via an infrared sensor associated with a computing device, an infrared signal from a second device attempting an unauthorized image capture of contents being displayed by a display device of the computing device. Subsequently, the computing platform may determine, via the computing platform, the contents being displayed by the display device. Then, the computing platform may retrieve a record of the contents being displayed by the display device. Then, the computing platform may determine a risk level associated with the infrared signal. Subsequently, the computing platform may perform, via the computing platform and based on the risk level, a remediation task to prevent the unauthorized image capture.

UV- and IR-absorbing materials with brown tint for sunglasses are described. The sunglass materials are prepared from a base glass through a post-fabrication process that includes ion exchange with silver. The tint of the sunglass material can be adjusted by controlling the level of ion exchange of the base glass with silver by varying the conditions of ion exchange. A wide range of tint is possible, including multiple shades of brown tint. In a typical process, a base glass having strong absorption in the UV and IR is fabricated and the resulting glass is subjected to a post-fabrication silver ion exchange process to control tint. The post-fabrication silver ion exchange process permits control of tint while maintaining strong UV and IR absorption and adequate transmittance in the visible.
