VHDA prepared at high pressures and temperatures appears to be mainly free of (nano)crystallinity. It is the thermally most stable amorphous solid phase of water at elevated pressures reported so far. Water's no man's land's low temperature boundary is thus shifted to higher temperatures by up to 4 K.

Abstract Precise determinations of the thermal conductivity of iron alloys at high pressures and temperatures are essential for understanding the thermal history and dynamics of the metallic cores of the Earth. We review relevant high-pressure experiments using a diamond-anvil cell and discuss implications of high core conductivity for its thermal and compositional evolution.
