Digging water channels in mineral stishovite

Stishovite has the same chemical formula as silica quartz (SiO2) but it has much higher density. While SiO2 is abundant on Earth's crust, it is also a major component of basalt, a type of igneous rock that is rich in iron ...

Trial by fire for the Ariane 6 upper stage

Validation testing continues for ESA's all-new Ariane 6 launch vehicle, with firing of its two upper stage engines to simulate the way they will have to operate together during a flight.

Ariane 6: Launch system tests progressing well

Teams preparing Ariane 6 for its inaugural flight successfully completed for the first time a launcher preparation and countdown sequence, on 18 July at Europe's Spaceport in Kourou, French Guiana.

Possible organic compounds found in Mars crater rocks

A study published in Science analyses multiple rocks found at the bottom of Jezero Crater on Mars, where the Perseverance rover landed in 2020, revealing significant interaction between the rocks and liquid water. Those rocks ...

How fine bubbles lead to more efficient catalysts

Catalysts are of utmost relevance for the production of chemicals and energy storage with hydrogen. Researchers at the Helmholtz Institute Erlangen-Nürnberg for Renewable Energy (HI ERN) and Friedrich-Alexander-Universität ...

Nanoporous intermetallic compounds that boost hydrogen production

Hydrogen has the highest energy density (120 MJ/kg) of all known substances, approximately three times more than diesel or gasoline, meaning it could play a pivotal role in sustainable energy systems. But the efficient production ...
