The work, published Sept. 13 [2016] in the journal Scientific Data, provides the surface energies and equilibrium crystal shapes of more than 100 polymorphs of 72 elements in the periodic table.

Small crystals known as "tumbled stones" have been softened and softly shaped by machine polishing and smoothing. Perfect for daily use, their soft form lets one have a flowing, balanced energy.

Quartz crystal resonators, including electric twins, are investigated. Electric twins are artificially formed in the usual AT-cut quartz crystal resonator before the deposition of electrodes. We have ...

The crystal has six sides, weighs 145 pounds and is 27 inches long. “It is a massive, massive crystal of quartz,” Fedak says.
