Multimodal electron microscopy of halide perovskite interfacial dynamics - Nature

Halide perovskite LEDs suffer rapid operational degradation due to ion migration and interfacial electrochemical reactions, requiring atomic-scale in situ imaging to understand degradation mechanisms and improve device stability.

Limitations of probing field-induced response with STM

We demonstrate how the apparent magnetic field induced lattice and CDW intensity change can be explained as a consequence of two independent experimental artifacts: a reconfiguration of atoms at the STM tip apex that alters the amplitudes of CDW modulations, and piezo creep, hysteresis and thermal drift, which artificially distort STM topographs.

Nanoscience is latest discipline to embrace large-scale replication efforts

Calling nanoscientists: your field needs you to try to replicate a landmark finding that quantum dots can act as biosensors inside living cells. As part of the first large-scale effort in the physical sciences to tackle the reproducibility crisis, researchers in France and the Netherlands are offering funds and resources in exchange for a few months of work. "We are trying to use

Large-scale analogue quantum simulation using atom dot arrays - Nature

Analogue quantum simulations are a useful tool for investigating these systems, particularly in regimes in which the applicability of numerical techniques is limited. For different simulator platforms, figures of merit include the electron bandwidth and interaction strength, temperature and the number of simulated lattice sites. Their use is further underscored by the ability to realize distinct lattice geometries, on-site degrees of freedom and by the physical observables that are accessible to experimental measurement.
