    The lanthanum-hydrogen system has attracted attention following the observation of superconductivity in LaH10 at near-ambient temperatures and high pressures. Here authors describe the high-pressure syntheses of seven La-H phases; they report crystal structures and remarkable regularities in rare-earth element hydrides.

    When hydronium ions are enriched in confined water, short hydrogen bonds (SHBs) form due to the constrained space of excess protons between pairs of water molecules. Here authors demonstrate a SHB network confined on the surface of ionic COF membranes with tunable -SO3H groups, with proton conductivity of 1389 mS cm-1 at 90 oC.

    Magnetic molecules have long been seen to hold promise in magnetic sensing applications. In this paper, Serrano et al show that a single layer of a magnetic molecule, a terbium based complex, is sensitive to the local magnetic field variation of a superconducting surface on which it is deposited.

    High throughput manufacturing of long length coated conductors requires fast epitaxial growth of high-temperature superconducting films. Here, Soler et al. report an ultrafast growth rates and high critical current densities of YBa2Cu3O7 films using a transient liquid-assisted growth method.

    Hydrogen-rich superhydrides are promising high-temperature superconductors which have been observed only at pressures above 170 GPa. Here the authors show that CeH9 can be synthesized at 80-100 GPa with laser heating, and is characterized by a clathrate structure with a dense 3-dimensional atomic hydrogen sublattice.

    Two-dimensional superconductors will likely have applications not only in devices, but also in the study of fundamental physics. Here, Wang et al. demonstrate the CVD growth of superconducting NbSe2 on a variety of substrates, making these novel materials increasingly accessible.

    Energy alignment in molecular tunnelling junctions is desirable for altering their electrical properties, however controllability is still an issue. Here the authors report a 2 orders-of-magnitude increase in the tunnelling current via chemical control of the energy-level alignment at a two-terminal junction.

    In BaFe2As2, the lattice couples strongly to the magnetic and electronic degrees of freedom, providing a way to control them. Here, by means of time-resolved X-ray scattering, the authors measure rapid lattice oscillations, which can induce changes in the material’s electronic and magnetic properties.

    LiTi2O4is the only known spinel oxide superconductor, but systematic investigations of its transport properties have been lacking so far. Here, the authors' analyses detect an unusual magnetoresistance, revealing spin-orbit fluctuations similar to those in high-temperature superconductors.

    Superconductivity in the iron pnictides is believed to be related to quantum critical fluctuations. Putzke et al. observe unexpected anomalies in the critical fields of BaFe2(As1−xPx)2that emerge close to its magnetic critical point, which they argue is a generic feature of quantum critical superconductivity.

    Understanding spin dynamics in the cuprates is vital to understanding the origin high-temperature superconductivity. X-ray and neutron spectra obtained by Ishii et al.suggest that the spins in electron-doped cuprates are itinerant, in contrast to recent evidence that in hole-doped cuprates they are localized.

    Unlike the other iron-based superconductors, the parent compounds of the alkaline iron selenide superconductors are insulators. Dai and colleagues examine the spin-wave excitations in these materials and uncover evidence for a common magnetic origin for all iron-based superconductors.

    Intercalating alkali metals into picene—a hydrocarbon with five linearly fused benzene rings—results in superconducting materials. Now, alkali-metal-doped phenanthrene, which consists of three fused benzene rings, is also found to be superconducting, opening up a broader class of organic superconductors.

    High critical temperature superconductors could be used to produce ideal electric power lines, but the misalignment of crystalline grain boundaries reduces current density. Here, pnictide superconductors are found to be more tolerant to misaligned grain boundaries than cuprates.

    In some iron-based materials, unconventional superconductivity can emerge near a quantum phase transition where long-range magnetic order vanishes. Giovannettiet al.show that the magnetic quantum phase transition in an iron pnictide superconductor is very close to the quantum tricritical point.

    In high-temperature superconductors, a very low density of states, the pseudogap, exists even above the critical temperature. Here, the authors show that this is also the case for a conventional superconductor, titanium nitride thin films, and that this pseudogap is induced by superconducting fluctuations.
