twinned crystal การใช้

• The color is dark steel-grey to iron-black, and the Twinned crystals are not infrequent.
• "' Steacyite "'is a complex silicate mineral containing thorium and uranium; formula twinned crystals.
• Tsumebite occurs at Morenci, Arizona, predominantly as twinned crystals associated with wulfenite, olivenite and the hyalite variety of opal.
• "' Tridymite "'is a high-temperature trillings " ( compound crystals comprising three twinned crystal components ).
• Commentators have interpreted the cage's compound shape as a reference to double and triple stars in astronomy, or to twinned crystals in crystallography.
• These twinned crystals have a hexagonal appearance, but are the result of a triplet of twins with each " twin " oriented at 120?to its neighbors and taking up 120?of the cyclic trilling.
• This modest coherence length means that the superconducting state is more susceptible to local disruptions from interfaces or defects on the order of a single unit cell, such as the boundary between twinned crystal domains.
• Crystals can be marred by twinning, which can occur when a unit cell can pack equally favorably in multiple orientations; although recent advances in computational methods may allow solving the structure of some twinned crystals.
