Uranium hexafluoride | UF6 - PubChem 60% of uranium absorbed into the blood is transported in the form of a bicarbonate complex, and 40% is bound to plasma proteins. The uranyl-bicarbonate complex is filtered out of the blood by the renal glomerulus and is passed into the tubules.The pH of urine decreases in the tubules, resulting in dissociation of the complex and release of the reactive uranyl ion.

Switchgear - Wikipedia switchgear may be a simple open-air isolator switch or it may be insulated by some other substance. An effective although more costly form of switchgear is the gas-insulated switchgear (GIS), where the conductors and contacts are insulated by pressurized sulfur hexafluoride gas (SF 6). Other common types are oil or vacuum insulated switchgear.
