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 ...

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

In this structure, lead and sulfur atoms should arrange themselves in a very ordered lattice, much like alternating red and blue Lego blocks. However, previous data has suggested that the lead ...

After weeks of rumors and speculation, LEGO officially unveils its newest set inspired by Nintendo's highly popular Mario Kart franchise.
