It was once thought that materials always become metallic under high pressure — like the metallic hydrogen theorized to make up Jupiter’s core — but Ashcroft and Jeffrey Neaton’s seminal paper two ...

Boca Raton's new LED streetlights will use up to 40 percent less energy than high-pressure sodium lamps, according to a city spokesperson. FPL estimates that's equivalent to taking 234 cars off ...

A University at Buffalo-led study has revealed the chemical bonding behind sodium's high-pressure transformation from shiny metal to transparent insulator.

Yes, Columbus is in fact working to convert all its streetlights to LED, but also yes, sometimes workers instead repair existing sodium-vapor lamps.

A new study has revealed the chemical bonding behind sodium's high-pressure transformation from shiny metal to transparent insulator. Travel deep enough below Earth's surface or inside the center ...
