Among the many discoveries on matter at high pressure that garnered him the Nobel Prize in 1946, scientist Percy Bridgman discovered five different crystalline forms of water ice, ushering in more than 100 years of research ...

(Phys.org)—Beginning level chemistry classes learn about Brønsted-Lowry acids. These acids dissociate in water to form an H+ ion and a negatively charged counterion. While this is a fundamental lesson, the actual mechanism ...
A single sheet of graphene, comprising an atom-thin lattice of carbon, may seem rather fragile. But engineers at MIT have found that the ultrathin material is exceptionally sturdy, remaining intact under applied pressures ...

(Phys.org)—Xenon, one of the noble gases, forms oxides that are not stable under ambient conditions, but are stable under very high pressure. In an effort to understand why the Earth's crust and atmosphere lacks the expected ...
Up until now, no material has been able to conduct current with no resistance at such high temperatures: Researchers at the Max Planck Institute for Chemistry in Mainz and the Johannes Gutenberg University Mainz observed ...

The interiors of several of our Solar System's planets and moons are icy, and ice has been found on distant extrasolar planets, as well. But these bodies aren't filled with the regular kind of water ice that you avoid on ...

(Phys.org) —The word "core" conjures up an image of something strong. However, new experiments show that the iron found in the Earth's core is relatively weak. This finding is based on x-ray spectroscopy and diffraction ...
