Single photon emitters in hBN: Limitations of atomic resolution imaging and potential sources of error

This study demonstrates that identifying single-photon emitters in hexagonal boron nitride using atomic-resolution ADF-STEM is fundamentally limited by sample thickness (beyond ~17 layers) and susceptible to misidentification due to residual threefold astigmatism, rendering the technique unreliable for the thicker flakes typically used in photonic research.

Dynamics of Long-lived Carriers in Molybdenum Carbide Nanosheets

This study reveals that Molybdenum Carbide (MoC) nanosheets exhibit significantly longer carrier lifetimes than other transition metal carbides due to restricted phonon decay pathways caused by the large mass difference between Mo and C atoms, offering a promising strategy for enhancing photothermal and photovoltaic device performance through efficient hot carrier utilization.

Data-Efficient Training of Linear ACE Potentials through Leverage-Guided Subset Selection of ASSYST Structure Pools

This paper demonstrates that leverage-guided, label-free subset selection of ASSYST structure pools can significantly reduce the DFT labeling workload (by 2–3x) required to train accurate linear Atomic Cluster Expansion potentials while maintaining competitive energy, force, and defect-level fidelity compared to random and other baseline sampling strategies.

Battery Material Comparisons Should Refocus on Diffusivity with Best Practices

This paper argues for a renewed focus on accurate ionic diffusivity measurements in battery material development, highlighting that current practices often neglect proper length-scale assessment and that cell-level performance can diverge from intrinsic diffusivity values, necessitating rigorous best practices to establish meaningful structure-property relationships.
