  • The investigation of thermal conductivity is crucial to the success of many modern technologies. Here the authors have reported an unusual glass-like thermal conductivity in a single crystal of layered halide perovskite, Cs3Bi2I6Cl3.

  • Whether a molecule or material can exist, and with what structures and energies, is of critical importance. For demanding calculations the efficiency of density functional theory makes it the only practical electronic structure theory available to help answer these questions. Now, an efficient density functional is shown to have unprecedented accuracy for a diverse set of bonded systems.

  • The Gossypium genus is used to investigate emergent consequences of polyploidy in cotton species; comparative genomic analyses reveal a complex evolutionary history including interactions among subgenomes that result in genetic novelty in elite cottons and provide insight into the evolution of spinnable fibres.

  • Amide group-containing polymer functionalized on carbon surfaces selectively interacts with the Co precursor, resulting in Co–N bond formation on PtCo nanoparticle surfaces. The electron transfer from Co to Pt is enhanced due to increased electronegativity difference between Pt and Co. In addition, the dissolution of Co and Pt during the oxygen reduction reaction (ORR) is retarded by the selective passivation of surface Co atoms and the decrease in the O-binding energy of surface Pt atoms. As a result, the catalytic activity and durability of the hybrid PtCo nanoparticles for the ORR are significantly improved by the electronic ensemble effects.
