Room-temperature superconductivity in a carbonaceous sulfur hydride.

One of the long-standing challenges in experimental physics is the observation of room-temperature superconductivity. Recently, high-temperature conventional superconductivity in hydrogen-rich materials has been reported in several systems under high pressure. An  important discovery leading to room-temperature superconductivity is the pressure-driven disproportionation of hydrogen sulfide (HS) to HS, with a confirmed transition temperature of 203 kelvin at 155 gigapascals.

Two- and three-dimensional extended solids and metallization of compressed XeF2.

The application of pressure, internal or external, transforms molecular solids into extended solids with more itinerant electrons to soften repulsive interatomic interactions in a tight space. Examples include insulator-to-metal transitions in O(2), Xe and I(2), as well as molecular-to-non-molecular transitions in CO(2) and N(2). Here, we present new discoveries of novel two- and three-dimensional extended non-molecular phases of solid XeF(2) and their metallization.
