Argonne scientists have unveiled new methods for controlling material properties. The breakthrough enables researchers to ...

It melts at 1410 C. The electronic configuration of the silicon atom is: (Ne)(3s) 2 (3p) 2, and the atomic radius is 0.132 nm. Silicon has the diamond cubic crystal structure with a lattice parameter ...

Zinc sulphide exists with two different crystal structures, the cubic zinc blend (top diagram) and the hexagonal Wurtzite (lower diagram). In the zinc blend structure the sulphur ions form an fcc ...

Researchers have discovered how to use light to change the arrangement of atoms in quantum dots. This intentional symmetry ...

Argonne researchers have shown that they can use light to temporarily alter the crystal symmetry within lead sulfide quantum dots. This process reduces the off-centering of lead atoms and affects the ...

Typically, lead sulfide is expected to form a cubic crystal structure, characterized by high symmetry similar to that of table salt. In this structure, lead and sulfur atoms should arrange ...

It is significantly 40% harder than natural diamonds, which typically have a cubic crystal structure. The material has been historically rare, found only in impact craters from meteorite collisions.
