The engines of tomorrow's PCs may be based not on silicon dioxide but on exotic new compounds such as perovskite oxide or even the stuff of life itself, DNA.
Iron, for example, becomes non-magnetic and may tend to migrate from perovskite toward another mineral as the pressure rises.
Some age determinations used atios measured on macrocrystal phlogopite; others used ratios from perovskite crystals.
The catalyst, which was first studied for use in catalytic converters in the early 1970s, includes the mineral perovskite with palladium.
