In 2016, Hogg designed the statuette for the Brit Awards, producing 13 trophies characterised by her distinctive use of glitter and metallic tones.

As Earth's metallic core formed, elements such as iron and molybdenum migrated inward and became concentrated there, leaving the mantle with much lower amounts.

Under a positive voltage, they found that nitrate ions "passivate" the catalyst by attaching to its surface, which prevents copper oxide from converting to metallic copper and instead results in the formation of nitrite ions.

"We refined our algorithms and used them to do a very detailed analysis of the metallic phase and oxide phase driving this very complex reaction."

The researchers believe that the test for fingerprints on brass they have developed could be adapted for other metallic surfaces, expanding its range of potential forensic applications, from firearm-related crimes to arson.
