Tunable Negative Thermal Expansion in Fe/Cr‐Substituted Nd2Co17 Compounds via Magnetoelastic Coupling

open access: yesAdvanced Science, EarlyView.
This study achieves anisotropic thermal expansion tuning in Nd2(Co1‐xFex)17‐yCry compounds via a magnetoelastic strategy. Variable‐temperature synchrotron X‐ray diffraction reveals that increased Fe content induces switchable lattice responses. Compositional control reduces the volume expansion coefficient αV by 20% (x═0.7) and modulates TC (442–625 K),

Tetrahedral DNA Nanostructure‐Based Biomimetic Nanovesicles Attenuate Sepsis‐Associated ARDS by Suppressing Glycolysis via the BMAL1/PFKFB3 Axis

open access: yesAdvanced Science, EarlyView.
Upon inhalation, RM@TNT could persist long‐term in the diseased lungs, while undergoing disintegration to release TNT specifically within the ROS‐rich pathological microenvironments of SA‐ARDS. The released TNT was then precisely delivered to AMs via Tuftsin, where it released Nob intracellularly to activate BMAL1 expression, thus inhibiting AM ...

Stable Diffusion Models Reveal a Persisting Human–AI Gap in Visual Creativity

open access: yesAdvanced Science, EarlyView.
This study examines visual creativity in humans and generative AI using the TCIA framework. Human artists outperform AI overall, yet structured human guidance substantially improves AI outputs and evaluations. Findings reveal that alignment with human creativity depends critically on contextual framing, highlighting both the promise and current ...
