  • The chemical stability of alkali halides has caused them to be exploited as inert media in high-pressure, high-temperature experiments. Here, NaCl and KCl are unexpectedly found to react with yttrium, dysprosium and iron oxide in a laser-heated diamond anvil cell, producing Y2Cl, DyCl, Y2ClC and Dy2ClC at ~40 GPa and 2000 K and FeCl2 at ~160 GPa and 2100 K.

  • The authors demonstrate that carbides with infinite chains of fused [C6] and [C5] rings are synthesized at deep planetary pressures and temperatures. Hydrolysis of these carbides may lead to polycyclic aromatic hydrocarbons in the Universe.

  • This work concerns a systematic study of Fe1-xO employing complementary methods of powder and single-crystal X-ray diffraction and synchrotron Mössbauer source spectroscopy up to 94 GPa and 1700 K. It presents a structural and magnetic transitional pressure-temperature diagram of Fe1-xO and demonstrates the complex physicochemical properties of simple Fe1-xO binary oxide under extreme conditions.
