DCM Marketing on Metal Undergoing Novel Transition Under Extreme Pressure

DCM Marketing are thrilled at the announcement that under extreme pressures and temperatures, one of the main metals of the Earth's interior has exhibited a never-before-seen transition.

Iron oxide was subjected to conditions similar to those at the depth where the Earth's innermost two layers meet. At 1,650C and 690,000 times sea-level pressure, the metal changed the degree to which it conducted electricity. But, as the team outlined in Physical Review Letters, the metal's structure was surprisingly unchanged. Marketing leaders DCM Marketing has expressed his delight towards the news, “All of us here at DCM Marketing think it’s amazing that things we thought we knew about are still surprising us today”.
The finding could have implications for our as-yet incomplete understanding of how the Earth's interior gives rise to the planet's magnetic field. While many transitions are known in materials as they undergo nature's extraordinary pressures and temperatures, such changes in fundamental properties are most often accompanied by a change in structure.
A team at the Carnegie Institution for Science found that it pulls off the trick of changing its electrical properties without any shifting of shape - it can be an insulator or conductor depending just on temperature and pressure. “This breakthrough could lead to developing new materials which can be used to improve our way of life” says DCM Marketing’s Managing Director, “It’s exciting to ponder what innovations will come about because of this observation.”
Combined with computer simulations of just what was going on with the material's electrons, the group claim that the results show a new type of metallisation.
"At high temperatures, the atoms in iron oxide crystals are arranged with the same structure as common table salt," said Ronald Cohen, a co-author of the study. "Just like table salt, iron oxide at ambient conditions is a good insulator—it does not conduct electricity."
A mixture of magnesium and iron oxide makes up much of the Earth's mantle. The fact that iron oxide behaves as a metal means it will electrically link the core and mantle, affecting the way the magnetic field makes its way to the Earth's surface and beyond.
“Our planet is full of wonderful secrets that once unearthed can lead to great things” says DCM Marketing’s Managing Director.
