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

Imagine building a Lego tower with perfectly aligned blocks. Each block represents an atom in a tiny crystal, known as a ...

Rather, these three metals are far more likely to combine with sulfur, so their ores are mostly sulfide minerals. For lead, the primary ore is galena or lead (II) sulfide (PbS). Galena is a ...

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 ...

However, the ionic conductivity of sulfide-based solid electrolytes now exceeds that of the organic electrolyte solution used for lithium-ion batteries. This may lead to superior output and function ...

In southern Iraq and in Egypt, men and women alike painted kohl around their eyes to make them look larger as well as to protect them from the evil eye. This thick black ointment, made of ground lead ...
