High Pressure Elements
Theoretical evidence supports electride behaviour in insulating high-pressure forms of potassium, sodium, and lithium. Here the isolated electron is stabilized by efficient packing which reduces enthalpy under external pressure. The electride is identified by a maximum in the electron localization function which distinguishes the electride from pressure-induced metallization. Electride phases are typically semiconducting or have very low conductivity.

Famous quotes containing the words high, pressure and/or elements:
“The duties which a police officer owes to the state are of a most exacting nature. No one is compelled to choose the profession of a police officer, but having chosen it, everyone is obliged to live up to the standard of its requirements. To join in that high enterprise means the surrender of much individual freedom.”
—Calvin Coolidge (1872–1933)
“Amid the pressure of great events, a general principle gives no help.”
—Georg Wilhelm Friedrich Hegel (1770–1831)
“Our institutions have a potent digestion, and may in time convert and assimilate to good all elements thrown in, however originally alien.”
—Herman Melville (1819–1891)
