  • Atomic structural changes in nanocrystals are still poorly understood. Here, the authors introduce time-resolved Brownian tomography to directly detect 3D atomic changes in Pt nanocrystals during oxidative etching and reveal disorder at sizes of ≈1 nm.

  • Arrays of thin-film transistors can be fabricated on the 5-inch wafer scale using solution-based processing of molybdenum disulfide and sodium-embedded alumina inks for the semiconductor and gate dielectric, respectively, yielding devices with room-temperature mobilities of up to 80 cm2 V−1 s−1.

  • High-index facet nanostructures are deliberately targeted and synthesized by using a data-driven approach that integrates high-throughput density functional theory calculations, machine learning and experimental validation. The effectiveness of this approach is shown by the discovery and subsequent synthesis of seven monometallic and four multimetallic tetrahexahedron-shaped high-index facet nanoparticles.

  • This study explores fractional quantum Hall physics in large-angle twisted bilayer graphene, revealing a 1/3 fractional quantum Hall state driven by strong interlayer Coulomb interactions. Monte Carlo simulations confirm unique topological ground states and transitions with applied displacement fields.

  • Nuclear spin-free materials like 28Si show promising electron spin coherence times, but qubit operation still suffers from low-frequency noise. Here the authors address this by applying open- and closed-loop feedback control methods including real-time Hamiltonian parameter estimation and dynamic voltage pulsing.

  • Wigner molecules, or correlated localized electron states, has been reported in semiconductor quantum dots, but their interaction with environment has been less explored. Here the authors use the spin multiplet structure of a three-electron Wigner molecule to enhance and control dynamic nuclear polarization.

  • High-throughput imaging has generally been challenging for scanning probe microscopy techniques. Here, the authors introduce binary-state scanning probe microscopy, which uses a cantilever-free elastomeric probes and a hierarchical measurement architecture for parallel topography imaging.
