A material that emits less energy than it absorbs has the potential to save some of the sunlight wasted by solar collectors.

Gallium's macroscopic properties are retained on a miniature scale in this nanodevice. Many applications have been found for carbon nanotubes1,2,3,4,5,6,7,8, and we can now add a role as a ...

In nature, gallium is never found as a free element and cannot be found in a substantial amount in any minerals. Rather, it exists in trace amounts in various compounds, ...

Gallium is a soft, silver-colored metal that most people have never heard of. It isn’t found on its own in nature but is taken from other metals like aluminum and zinc during processing.

Gallium is a metal with an extremely low melting point--about 85 degrees Fahrenheit. The shiny metal, which isn't found by itself in nature, can be melted just by placing it in your hand.

Two obscure yet crucial metals, gallium and germanium, are the latest pawns in the escalating US-China trade war. On Dec. 3, China announced an export ban on both metals to the US in a tit-for-tat ...

The UK considers gallium to be critical to its manufacturing interests, though sees germanium as less important. Where they come from China controls about 60% of all germanium supplies.

Just one month after China announced it would curb exports of germanium and gallium, both essential for making semiconductors, its overseas shipments of the materials fell to zero.
