density

"If the object has a liquid central core, then a captured PBH can absorb the liquid core, whose density is higher than the density of the outer solid layer," Stojkovic says.

They varied the number of rings, the density of "grains," and the strength of lateral forces applied to the rings.

"We asked colleagues to use density functional theory to look into why water matters when it comes to the stability of nickel."

The results showed that in almost all cases, measured bandwidths were higher than predictions by widely used models of the galaxy, highlighting a need for updates to current ISM density models.

Higher current density capability could also enable new applications in automotive and specialty industrial lighting, while faster switching speeds could find applications in visible-light communication technologies and VR glasses.
