RHINOCEROS - TiO2 Glossary

µgm^-3:: micrograms per cubic metre cubed.
µµm:: 1µm = 1 micron = 1 millionth of a metre.
Anatase:: One of the three mineral forms of Titanium Dioxide.
Free Radical:: An atom or molecule with an unpaired electron in its outer orbit, Highly reactive.
Nano:: Prefix meaning one billionth. 1 nanometer is about the diameter of 3 to 6 atoms.
Oxidation:: When an element loses an electron it is said to be oxidised, this usually occurs with the addition of oxygen, hence oxidation.
Oxyhydride (OH):: .ion consisting of one oxygen and one hydrogen atom.
Photocatalyst:: A photocatalyst is a substance which accelerates a reaction that requires light.
Rutile:: One of the three mineral forms of Titanium Dioxide.
Titanium:: A natural metallic element.
UV:: Ultra Violet; Invisible light with wavelengths between 1nm (X-ray) and 400nm (blue visible light), approximately.
VOC:: Volatile organic compound; any organic compound that evaporates readily to the atmosphere. Has a carbon-based chemical substance, produces noxious fumes and is found in many caulks, stains, paint and adhesives.
