Regulators usually are part of the car's alternator, although many cars, particularly older cars and modern American models, have exterior voltage regulators. Alternators or generators are used to generate power, which is fed into the car's battery to maintain a full charge.
Titanium dioxide as used in sunscreens is commonly modified with other ingredients to ensure efficacy and stability. Examples of what are known as surface modifier ingredients used for titanium dioxide include stearic acid, isostearic acid, polyhydroxystearic acid, and dimethicone/methicone copolymer.
Titanium is a transition metal which is very strong and light (4.4 gm/cm3). It has a high melting point (1800Â°C) and finds application in aircraft wings, particularly at points which are subjected to the high heat of exhaust. Titanium dioxide in powder form is very white and is used to advantage as a pigment in special paints and face powders. Titanium dioxide, TiO2, in crystalline form appears in the mineral rutile. It may be colored by small amounts of other metal oxides and has been used for gems. Titanium dioxide also makes up the minerals Brookite and anatase. Titanium and iron together form the oxides ilmenite, FeTiO3, and pseudobrookite, Fe2TiO5.
