  • Amorphous chalcogenide alloys are promising for Ovonic threshold switching selectors, yet elemental chalcogen based-material design is hindered by poor glass-forming ability of chalcogen species. Hur et al. show defect-mediated switching and self-regulated oscillations in an amorphous Te phase stabilized via on-device quenching.

  • Experiments on a noisy 127-qubit superconducting quantum processor report the accurate measurement of expectation values beyond the reach of current brute-force classical computation, demonstrating evidence for the utility of quantum computing before fault tolerance.

  • Catalytic CO2 dissociation pathways are selectively determined by surface geometry in heterogeneous catalysis. The authors find that the stepped Cu surfaces effectively affect CO2 activation in elementary reaction steps at the atomic level

  • Understanding the atomic structure of active sites is important but challenging due to the complexity of heterogeneous systems. Here, the dynamic nature of Pt/CeO2 during the water-gas-shift reaction is studied using multiple in situ characterization tools to establish structure-performance relationships.
