A Leap Toward Practical Superconductors

With hydrogen sulfide, scientists make the latest leap forward on the road to room-temperature superconductivity.

Superconducting upper critical fields as a function of temperature for two samples under pressures of 150 and 170 GPa.

Fluorine in a Fullerene

Researchers have generate the first fluorinated and metal-encapsulated carbon nanocages, a process that could lead to clean energy applications such as plastic solar cells.

Up to two fluorine atoms are added to the Sc3N@C80 fullerene cage, as shown in this FT-ICR mass spectrum.

    Functionalizing molecular nanocarbon with fluorine atoms

    Researchers have discovered a new method to create encapsulated carbon nanomaterials that contain fluorine. Known as fullerenes, these nanocages are promising candidates for clean energy applications.

  • Quasi-2D to 3D Fermi surface topology change in Nd-doped CeCoIn5
    5 November 2018
    Quasi-2D to 3D Fermi surface topology change in Nd-doped CeCoIn5

    Scientists found that the emergence of an exotic quantum mechanical phase in Ce1-xNdxCoIn5 is due to a shape change in the Fermi surface. This finding ran counter to theoretical arguments and has led investigators in new directions.

  • Destruction of Weyl nodes and a new state in tantalum arsenide above 80 teslas
    17 September 2018
    Destruction of Weyl nodes and a new state in tantalum arsenide above 80 teslas

    Weyl metals such as tantalum arsenide (TaAs) are predicted to have novel properties arising from a chirality of their electron spins. Scientists induced an imbalance between the left- and right-handed spin states, resulting in a topologically protected current. This was the first time this phenomenon, known as the chiral anomaly, has been observed.
