Quantification of Magnetic Interactions in van der Waals Heterostructures Using Lorentz Transmission Electron Microscopy and Off‐Axis Electron Holography

open access: yesAdvanced Materials, EarlyView.
Cross‐sectional Lorentz TEM and off‐axis electron holography visualize the magnetic domain structure and quantify interlayer coupling in Fe3GeTe2/graphite/Fe3GeTe2 heterostructures. A stray‐field coupling length of 37±$\pm$7 nm marks the onset of domain misalignment between the layers.

Wafer‐Scale Direct Growth of Ultraclean Monolayer Amorphous Carbon on c‐Sapphire by Remote Catalytic Dehydrogenation

open access: yesAdvanced Materials, EarlyView.
Remote catalytic dehydrogenation enables the direct growth of monolayer amorphous carbon on a 2‐inch sapphire wafer by thermal CVD. Spatial separation of the catalyst from the growth substrate eliminates metallic residue and post‐growth processing, yielding a wafer‐scale uniform film with a random polygonal sp2‐hybridized carbon network that exhibits ...

Life‐Like Ferrous Oxide Microspheres from Kombucha

open access: yesAdvanced Materials Interfaces, EarlyView.
Kombucha bacterial cellulose, sodium alginate, and ferrous nitrate self‐assemble into membrane‐enclosed iron oxide microspheres. These microspheres bud daughter vesicles, sustain 24‐h electrochemical oscillations, and filter theta‐band signals.

Enhanced Xylene Sensing Performance of Fe‐Doped NiO Nanosheet Arrays via In Situ Growth

open access: yesAdvanced Materials Interfaces, EarlyView.
Xylene is a hazardous volatile organic compound (VOC) widely present in industrial environments, and achieving sensitive and stable detection of xylene remains a significant challenge for gas sensors. Here, a one‐step hydrothermal route was employed to in situ grow p‐type Fe‐doped NiO nanosheet arrays on ceramic tubes for xylene detection.

3D‐Printed Dual‐Doped Ag2Se‐Based Thermoelectric Films With Enhanced Thermal Stability

open access: yesAdvanced Materials Technologies, EarlyView.
Sb–Se dual doping enhances the thermal stability of Ag2Se‐based thermoelectric systems. The compositionally tuned nano‐ink is printed into flexible films by direct ink writing (DIW), retaining improved thermoelectric properties after annealing up to 400°C.
