These include tungsten, which is difficult to source and a crucial material for the aerospace industry, tellurium, widely used for solar panels, and molybdenum, which is used to strengthen steel alloys.

"We believe our method will generalize to other materials, such as tin, selenium, tellurium and related alloys with low melting points, and it could be interesting to explore for future flexible electronic circuits."

Through their investigation, the team discovered that the charge of tellurium oxide, a rare earth metal, increases in oxygen-deficient environments.

The researchers observed evidence of tellurium, one of the rarest elements on Earth.

The spectrum has broad lines that show the material is ejected at high speeds, but one feature is clear: light emitted by tellurium, an element rarer than platinum on Earth.
