Thermally Drawn Multifunctional All‐Hydrogel Fibers for Anti‐Fibrotic and Multimodal Neural Interfaces

open access: yesAdvanced Materials, EarlyView.
Hydrogels demonstrate material properties that mimic the mechanical and chemical environments of biological tissues. Yet, they face challenges during their integration into 3D interfaces. By identifying a class of thermoplastic hydrogels, a strategy is developed to pattern hydrogels in thermally drawn fibers.

Adsorption Dynamics and Electric Double Layer Properties at Pt(100) Electrodes

open access: yesAdvanced Materials Interfaces, EarlyView.
Atomic‐scale structures at the Pt(100) interface are investigated using advanced experimental techniques and density functional theory. The coverage and arrangement of hydrogen and hydroxide evolve with potential (V vs. reversible hydrogen electrode, RHE), revealing the optimal interface coverage. Color legend: H: white, O: red.

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 ...

UV Photosensitive PMMA‐Based Nanocomposites Micropatterned by Laser for Product Traceability and Anticounterfeiting Applications

open access: yesAdvanced Materials Interfaces, EarlyView.
We introduce an anti‐counterfeiting solution using photoluminescent nanoparticles in PMMA polymer matrices. Through UV‐activated polymerization without photoinitiators, achieved via solvent modification, secure micromarkers are created within seconds using industrial laser systems.

Thermal Annealing Enhances Piezoelectricity and Regenerative Potential of PVDF‐TrFE Nanofiber Scaffolds

open access: yesAdvanced Materials Technologies, EarlyView.
Thermal annealing improves the structure, stiffness, and piezoelectric properties of poly(vinylidene flouride‐trifluoroethylene) (PVDF‐TrFE) nanofiber scaffolds. These annealed scaffolds promote Schwann cell proliferation and matrix remodeling in vitro and demonstrate in vivo biocompatibility.

Hygromnemics: Programmable Material Memory Matter Actuators via Wet Pre‐Constraining

open access: yesAdvanced Materials Technologies, EarlyView.
Humidity‐based pre‐constraining creates hygromnemics‐shape memory matter. From identical biocomposites actuation in dry and wet states is obtained via hygromnemic and hygromorphic actuation, respectively. Hygromnemic actuators present long‐ and short‐term shape memory abilities.

An Ultra‐Sub‐Wavelength Microwave Polarization Switching Antenna for Covert Communication Implemented With Directed Surface Acoustic Waves in an Artificial Multiferroic Magnonic Crystal

open access: yesAdvanced Materials Technologies, EarlyView.
A surface acoustic wave (SAW) launched in a two‐dimensional periodic array of magnetostrctive nanomagnets on a piezoelectric substrate excites spin waves in the nanomagnets which radiate electromagnetic waves in space. The polarization of the emitted beam in particular directions and at particular frequencies can be switched between horizontal and ...
