Annealing In Space: How NASA Saved JunoCam In Orbit Around Jupiter

The Juno spacecraft was launched towards Jupiter in August of 2011 as part of the New Frontiers series of spacecraft, on what would originally have been a 7-year mission, including a nearly 5 year …

Comment la Nasa a hacké une caméra à 700 millions de kilomètres de la Terre

La Nasa a utilisé une technique inédite pour réparer à distance une caméra embarquée sur la sonde Juno, en orbite autour de Jupiter. Endommagée par les radiations, elle a tout de même pu être manipulée avec succès. Dans quelques semaines, le 5 août 2025, Juno fêtera le 14ème anniversaire de son lancement. Un âge

Different phase leads to different transport behavior in Pb$_9$Cu(PO$_4$)$_6$O compounds

The recent claimed room-temperature superconductivity in Cu-doped lead apatite at ambient pressure are under highly debate. To identify its physical origin, we studied the crystal structures, energy band structures, lattice dynamics and magnetic properties of the parent Pb$_{10}$(PO$_4$)$_6$O compound, in which two different phases of the LK-99 compound are analyzed in detail. Our results show that the Pb$_{10}$(PO$_4$)$_6$O compound is an indirect band gap semiconductor, where Cu doping at the 4$f$ site of Pb leads to a semiconducting to half-metallic transition. Two half-filled flat bands spanning the Fermi energy levels are present in the 4$f$-phase of LK-99, which are mainly formed by hybridization of the $d_{x^2-y^2}$ and $d_{zy}$ orbitals of Cu with the 2$p$ orbitals of O. In addition, 6$h$-phase of LK-99 always has spin polarity at the bottom of the conduction band and at the top of the valence band, making the material a bipolar magnetic semiconductor. Our results are basically consistent with the recent experimental transport properties of LK-99 posted on arXiv:2308.05778.
