Triggered Ferroelectricity in HfO2 From Hybrid Phonons and Higher‐Order Dynamical Charges
Advanced Materials, EarlyView.We combine first‐principles calculations, LGD theory and group theory to demonstrate the mechanism of hybrid‐triggered ferroelectricity in HfO2${\rm HfO}_2$, enabled by trilinear and quadlinear couplings between stable polar and nonpolar modes. HfO2${\rm HfO}_2$ hosts unconventional interplay between structure modes where substantial contribution to ...

All‐Optical Reconfigurable Physical Unclonable Function for Sustainable Security
Advanced Materials, EarlyView.An all‐optical reconfigurable physical unclonable function (PUF) is demonstrated using plasmonic coupling–induced sintering of optically trapped gold nanoparticles, where Brownian motion serves as a robust entropy source. The resulting optical PUF exhibits high encoding density, strong resistance to modeling attacks, and practical authentication ...

Advanced Materials, EarlyView.Precursor carbon stoichiometry programs internal strain and oxygen substitution in Ti3AlCxO2‐x, deterministically switching Ti3CxO2‐xTz MXenes between highly aligned 2D nanosheets and spontaneous 1D nanoscrolls. This synthesis‐stage architecture control enables ultrathin X/W‐band EMI shielding with outstanding mass‐normalized performance and bending ...

Advanced Materials, EarlyView.Ga‐on‐In substitution coupled with Zn vacancies in Zn3In2S6 creates a dopantdefect synergy that weakens InO bonding and induces electronhole asymmetry. The resulting spatial charge separation directs the two‐electron oxygen reduction pathway, enabling efficient artificial photosynthesis of H2O2 with a production rate of 187.8 µmol g−1 min−1 ...

Why Is the Mechanism Underlying the Chiral‐Induced Selectivity Effect Still Challenging?
Advanced Materials, EarlyView.The chiral‐induced spin selectivity (CISS) effect is observed in many experimental configurations and for different materials. However, there are theoretical challenges in attempting to explain those results. A qualitative framework for explaining all the results is presented.

Chiral Metal Halide Perovskites for Spin‐Polarized Light‐Emitting Diodes
Advanced Materials, EarlyView.Chiral metal–halide perovskites offer a route to circularly polarized light without external polarizers. This Perspective compares two spin‐light emitting diode concepts: intrinsically chiral emissive layers and chiral spin‐filter interlayers that inject spin‐polarized carriers into efficient achiral emitters.

Advanced Materials Interfaces, EarlyView.A near‐infrared photosensitizer that facilitates efficient solid‐state photon upconversion by recycling triplets formed within a fullerene‐based donor–acceptor bulk‐heterojunction system is demonstrated. Spectroscopic investigations reveal that the energy of photogenerated charge transfer states of triplet character (3CT) is subsequently transferred to

Suppressing Metal–Molecule Charge Transfer With a Phosphorus Interlayer
Advanced Materials Interfaces, EarlyView.Phosphorus forms stable reconstructions with remarkable properties on various metal substrates. Here, using a spectroscopic approach, its role as an effective buffer layer on Cu(110) is demonstrated, preventing charge transfer to adsorbed Zn‐tetraphenylporphyrins (ZnTPP).
