Spatially Encoded Polaritonic Ultra‐Strong Coupling in Gradient Metasurfaces with Epsilon‐Near‐Zero Modes

open access: yesAdvanced Materials, EarlyView.
Dielectric dual gradient metasurfaces supporting quasi‐bound‐states‐in‐the‐continuum are leveraged to spatially encode both the spectral and coupling parameter space and demonstrate ultra‐strong coupling to an epsilon‐near‐zero mode in an ultra‐thin SiO2 layer.The platform achieves exceptional mode overlap, reaching a normalized coupling strength of η =

Tunable Magnetism and Intrinsic Exchange Bias in Al‐Substituted Terbium Iron Garnet

open access: yesAdvanced Materials, EarlyView.
Al substitution in terbium iron garnet thin films enables continuous tuning of the magnetic compensation temperature from 190 K to above room temperature. Near compensation, a giant intrinsic exchange bias emerges, whose sign and stochasticity can be controlled by external fields and cooling history. This approach provides new routes to engineer garnet

Challenges of II‐VI and III‐V Blue Quantum Dot Light‐Emitting Diodes

open access: yesAdvanced Materials, EarlyView.
Blue‐emitting electroluminescent quantum dot light‐emitting diodes (QD‐LEDs) face critical challenges that limit their practical application, including short operational lifetimes, low color purity, broad spectral linewidths, and unpredictable transient effects like blinking and positive aging.

Acidity‐Mediated Metal Oxide Heterointerfaces: Roles of Substrates and Surface Modification

open access: yesAdvanced Materials, EarlyView.
The role of local space charge, not only at heterointerfaces, but also at grain boundaries, influenced by surface acidity modulation is elucidated through model platforms composed of Pr‐doped ceria (mixed ionic‐electronic conducting oxide) nanowire arrays.

Archeo‐Inspiration from the Cultural History of Glass: Historic Accounts, Anecdotes and Hard Facts as Challenges to Modern Material Science

open access: yesAdvanced Materials, EarlyView.
Glass, historically valued for its purity and durability, has long inspired artists and societies. This article introduces the concept of “Archeo‐Inspiration”, drawing on cultural and historical contexts of glass to guide future material innovations.
