• High-tech Metals Germanium and Gallium from the Deep Sea?
  

  Germanium and gallium are two metals that are of great importance for modern high technologies. Both are important raw materials for the semiconductor industry, for fiber optic cables and for photovoltaics. They are thus essential components for shaping electromobility and the energy transition. Usi more

• Geochemists measure new composition of Earth’s mantle
  

  What is the chemical composition of the Earth’s interior? Because it is impossible to drill more than about ten kilometres deep into the Earth, volcanic rocks formed by melting Earth’s deep interior often provide such information. Geochemists at the Universities of Münster (Germany) and Amsterdam (N more

• New Measurement Device: Carbon Dioxide As Geothermometer
  

  For the first time it is possible to measure, simultaneously and with extreme precision, four rare molecular variants of carbon dioxide (CO2) using a novel laser instrument. It is thus able to measure the temperature during the formation of CO2-binding carbonates and carbonaceous fossils completely more
