Unlocking NIR‐II Photoluminescence in 2D Copper Tetrasilicate Nanosheets through Flame Spray Synthesis

open access: yesAdvanced Materials, EarlyView.
A flame‐spray‐pyrolysis method is presented to synthesize ultra‐bright CTS nanosheets with tunable NIR‐II emission. Achieving quantum yields up to 34%, these materials support high‐speed imaging and enable super‐resolution in vivo applications such as transcranial microcirculation mapping and macrophage tracking.

Standalone Integrated Magnonic Devices

open access: yesAdvanced Materials, EarlyView.
A standalone (not requiring external bias magnetic field) and tunable magnonic device is reported with all‐electric input and output, fully integrated on silicon (total footprint of 100 × 150 µm) and 3–8 GHz frequency band. This is achieved by monolithic integration of a CoFeB conduit with RF antennas and an assembly of NiFe and SmCo micromagnets ...

Triphasic Inter‐Dimensional WS2/Magnetic Lithium Iron Oxide Nanocomposite for Electromagnetic Interference Shielding

open access: yesAdvanced Materials Interfaces, EarlyView.
This study investigates the electromagnetic interference shielding performance of a multiphasic nanocomposite consisting of granular magnetic ferrite (α‐LiFe5O8/α‐LiFeO2) and conductive WS2 nanoflakes. It establishes a clear correlation between the shielding performance and relative fractions of the phases with distinct morphologies/dimensionalities ...
