Scalable Polyelectrolyte Complex‐Based Sorbent With Hourly Sorption−Desorption Cycles for Multicyclic Atmospheric Water Harvesting in Arid Environments

Advanced Functional Materials, EarlyView.
A polyelectrolyte complex‐based sorbent is produced by scalable, environmentally benign aqueous phase inversion. Its porous, LiCl‐ and GO‐integrated architecture enables hourly adsorption−desorption cycles at low relative humidity (RH < 30%). A large‐scale prototype achieves multicyclic, solar‐driven atmospheric water harvesting of 1.37 L kg−1 day−1 ...

Investigating Disturbance‐Induced Misoperation of Grid‐Following Inverter‐Based Resources

IET Generation, Transmission & Distribution
ABSTRACT The rapid integration of grid‐following inverter‐based resources (GFL‐IBRs) has increased the importance of their dynamic behaviour during disturbances. Simultaneously, there are increasing number of reports about the misoperation or inadvertent disconnection of GFL‐IBRs during disturbances.

Bioinspired Stabilization of Fluorescent Au@SiO2 Tracers for Multimodal Biological Imaging

Advanced Functional Materials, EarlyView.
This study demonstrates a bioinspired stabilization strategy for fluorescent gold‐silica nanoparticles. Inspired by natural biosilica maturation, high‐temperature calcination transforms the silica shells, preventing dissolution in cell culture media and intracellular environments.

Indirect Band Edge and Chain‐Locked Linear Dichroism in the Quasi‐1D Van der Waals Antiferromagnet AgCrP2S6

Advanced Functional Materials, EarlyView.
AgCrP2S6 reveals a momentum‐indirect band edge (≈1.35 eV) and chain‐locked linear dichroism: the first direct transitions emerge at 1.6–1.8 eV for E||a. Resonant Raman and photoemission corroborate this assignment. In ACPS/graphene heterostructures, photocurrent turns on above ≈1.5 eV and follows the same polarization selection rules (anisotropy ≈0.53),

Adaptive‐saturation‐based transient stability enhancement for grid‐following inverters

IET Power Electronics
Abstract This paper proposes an adaptive saturation module to enhance the transient stability of grid‐following inverters after voltage‐dip inception and fault‐clearance moment. The equal‐area criterion reveals that a large acceleration area will be obtained due to the step change of current reference according to grid codes, which ...

Biointerface Membranes Orchestrating Site‐Specific Osteoimmunomodulatory and Antibacterial Effects for Enhanced Osseous Regeneration in Periodontal Therapy

Advanced Functional Materials, EarlyView.
Here, a biointerface membrane engineered with site‐specific interfacial properties is developed. During implantation between gingival and bone defect, the membrane creates a pro‐osteogenic microenvironment, precisely modulates cellular activities at each biointerface, and facilitates the orchestration of complex healing events, ultimately leading to ...

Color Routing and Beam Steering of Single‐Molecule Emission with a Spherical Silicon Nanoantenna

Advanced Functional Materials, EarlyView.
We experimentally demonstrate broadband directional emission from single molecules using a single spherical silicon nanoparticle assembled via DNA origami. By varying nanoparticle (NP) size and emitter position, we achieve unidirectional emission, beam steering, and color routing at the nanoscale, revealing modal interference as the underlying ...
