Atomic‐Scale Detection of Néel Vector Switching in the Single‐Layer A‐Type Antiferromagnet Cr 2 S 3 ‐2D

ABSTRACT The detection of Néel vector switching in a single‐layer A‐type antiferromagnet marks an important step toward functional two‐dimensional spintronics. Here, ‐2D, grown on graphene on Ir(110), is established as a first single‐layer A‐type antiferromagnet. Spin‐polarized s...

Ultra-compact plasma photocathode in a hybrid wakefield accelerator

Abstract Plasma-based particle accelerators, realized by driving plasma waves with either an intense laser pulse or particle beam, offer accelerating fields orders of magnitude higher than conventional accelerators. This enables sources of highly relativistic electron beams with...

Disentangling surface and bulk properties of Ta3N5 photoanodes

Abstract Understanding how material and defect characteristics govern photoelectrochemical performance is essential for developing efficient and stable photoelectrodes. Although bulk properties are often emphasized, surfaces and interfaces can equally determine activity and stabi...

External validation of a top-ranked model from the RSNA pulmonary embolism detection challenge: assessment of generalizability

Abstract To externally validate the RSNA 2020 challenge 2 nd -place deep-learning (DL) algorithm for detecting pulmonary embolism (PE) on computed tomography pulmonary angiography (CTPA) scans with additional focus on subsegmental-only PEs (SSPE). Between 2015 and 2022 1,038 CTPA...

Bioinspired Large-AreaPolymeric Cucurbituril Monolayerswith Ultrahigh-Density Nanopores Enabling Reversible Charge-Gatingof Ion Transport via Host–Guest Recognition

Abstract Achieving precise control over ion and molecular transport under subnanometer confinement, especially beyond passive sieving, remains challenging in nanofluidics and membrane science. Here, we present a bioinspired strategy that enables the formation of subnanometer chan...
