    The interaction of localized and conduction electrons in some heavy fermion materials is believed to give rise to a Kondo insulating state. Kushwaha et al. present evidence that Ce3Bi4Pd3 is a Kondo insulator with a gap small enough to be driven into a Fermi liquid phase with accessible magnetic fields.

    Bulk band inversions in solids may unlock topological surface phenomena and symmetry-protected states. Here, the authors generate a surface state band inversion in the nonsymmorphic semimetal NbGeSb, leading to protected crossing points in the resulting spin-orbital entangled surface band structure.

    During carrier multiplication, high-energy free carriers in a given material relax by generation of additional electron-hole pairs. Here, the authors report evidence of carrier multiplication in multilayer MoTe2 and WSe2 films with up to 99% conversation efficiency.

    A significant challenge in understanding the behaviour of strongly correlated materials is their sensitivity to composition. Here the authors show that stoichiometric CaFe3O5 avoids the electronic phase separation reported in a non-stoichiometric sample, and also exhibits an incommensurate magnetic phase.

    The activation mechanism of integrin αVβ8 differs from other integrins. Combining X-ray crystallography, hydrogen deuterium exchange mass spectrometry and mutation, the authors reveal structural features responsible for these differences and provide insights into how typical integrins are regulated.
