The first self-cleaning glass was based on a thin film titania coating. [3] The film can be applied by spin coating of organo-titanate chelated precursor (for example titanium iso-tetrapropoxide chelated by acetylacetone), followed by heat treatment at elevated temperatures to burn the organic residues and to form the anatase phase.
One of the most commonly used self-cleaning products, titanium dioxide, utilizes a unique self-cleaning mechanism that combines an initial photocatalytic step and subsequent superhydrophilicity. A titanium dioxide coating, typically on glass windows, when exposed to UV light, will generate free electrons that will interact with oxygen and water ...
Conservation-restoration is the practice of cleaning and discovering the original state of an object, investigating the proper treatments and applying those treatments to restore the object to its original state without permanently altering the object, and then preserving the object to prevent further deterioration for generations to come (Caple, p. 5-6).

With winter weather often comes drafty windows. Incorrectly installed or aging windows can let drafty cold air in, reducing your home's energy efficiency and increasing its heating bill.
A recent (2001 Pilkington Glass) innovation is so-called self-cleaning glass, aimed at building, automotive and other technical applications. A nanometre-scale coating of titanium dioxide on the outer surface of glass introduces two mechanisms which lead to the self-cleaning property.
A typical installation of insulated glass windows with uPVC frames. Possibly the earliest use of double glazing was in Siberia, where it was observed by Henry Seebohm in 1877 as an established necessity in the Yeniseysk area where the bitterly cold winter temperatures regularly fall below -50 °C, indicating how the concept may have started: [2]
Air Fresheners. Why they're a waste: The air-freshener industry continues to rake in the cash, and it's no wonder: Scented-oil refills for an outlet freshener can cost upward of $2.50 a pop, and ...
Coatings in high temperature applications may be designed to exhibit self-healing performance through the formation of a glass. In such situations, such as high emissivity coatings, the viscosity of the glass formed determines the self healing ability of the coating, which may compete with defect formation due to oxidation or ablation.
