What do the crystal structure of strontium disilicide, liquid crystals used for electro-optics and the wings of the Green Hairstreak butterfly have in common? All can be mathematically described ...

Its melting point is 768 C, and it boils at 1380 C. The electronic configuration of Strontium is (Kr)(5s 2). Its atomic radius is 0.215 nm and the (+2) ionic radius is 0.113 nm. In the solid state ...

and Jie Wu of the Condensed Matter Physics and Materials Science Division and collaborators at Cornell found evidence of an electronic 'liquid crystal' state in a superconductor called strontium ...
