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:
“Someday soon, we hope that all middle and high school will have required courses in child rearing for girls and boys to help prepare them for one of the most important and rewarding tasks of their adulthood: being a parent. Most of us become parents in our lifetime and it is not acceptable for young people to be steeped in ignorance or questionable folklore when they begin their critical journey as mothers and fathers.”
—James P. Comer (20th century)
“Much of the pressure contemporary parents feel with respect to dressing children in designer clothes, teaching young children academics, and giving them instruction in sports derives directly from our need to use our children to impress others with our economic surplus. We find “good” rather than real reasons for letting our children go along with the crowd.”
—David Elkind (20th century)
“Nature confounds her summer distinctions at this season. The heavens seem to be nearer the earth. The elements are less reserved and distinct. Water turns to ice, rain to snow. The day is but a Scandinavian night. The winter is an arctic summer.”
—Henry David Thoreau (1817–1862)
