Room-temperature superconductivity in a carbonaceous sulfur hydride.
Snider E, Dasenbrock-Gammon N, McBride R, Debessai M, Vindana H, Vencatasamy K, Lawler KV, Salamat A, Dias RP. Snider E, et al. Nature. 2020 Oct;586(7829):373-377. doi: 10.1038/s41586-020-2801-z. Epub 2020 Oct 14. Nature. 2020. PMID: 33057222 Retracted.
An important discovery leading to room-temperature superconductivity is the pressure-driven disproportionation of hydrogen sulfide (H(2)S) to H(3)S, with a confirmed transition temperature of 203 kelvin at 155 gigapascals(3,6). Both H(2)S and CH(4) readily mix with hydroge …

Observation of the Wigner-Huntington transition to metallic hydrogen.
Dias RP, Silvera IF. Dias RP, et al. Science. 2017 Feb 17;355(6326):715-718. doi: 10.1126/science.aal1579. Epub 2017 Jan 26. Science. 2017. PMID: 28126728
We fit the reflectance using a Drude free-electron model to determine the plasma frequency of 32.5 2.1 electron volts at a temperature of 5.5 kelvin, with a corresponding electron carrier density of 7.7 1.1 10(23) particles per cubic centimeter, which is consistent with th …

Under conditions typical of polluted urban settings, naphthalene may well contribute to nucleation and the growth of the smallest particles, whereas the more abundant alkyl benzenes may overtake naphthalene once the particles have grown beyond the point where the Kelvin ef …

The accelerating growth may result from increased photolytic production of condensable organic species in the afternoon, and the presence of a possible Kelvin (curvature) effect, which inhibits organic vapour condensation on the smallest particles (the nano-Kohler theory), …
