Strong Proton‐Phonon Coupling Drives Fast Ion Transport in Perovskites

open access: yesAdvanced Science, Volume 13, Issue 9, 13 February 2026.
Experimental and computational phonon analysis of ABO3‐type proton conductor BaSnO3 shows that substitution on the B‐site with yttrium forms an imaginary phonon mode which is instrumental for the function as proton conductor. This overcompensates the adverse proton trapping effect of the yttrium.

NIR‐Triggered Upconversion‐Perovskite Heterostructures for Non‐Genetic, Implant‐Free Optoelectronic Neuromodulation

open access: yesAdvanced Science, Volume 13, Issue 8, 9 February 2026.
The Single‐Nanostructured Optoelectronic Vehicle for neuromodulation Activation (SNOVA) establishes a paradigm for non‐genetic, implant‐free neuromodulation. By integrating NIR‐excitable UCNPs with broadband‐absorbing perovskite QDs, SNOVA efficiently converts deeply penetrating light into localized electric fields that modulate neuronal ion dynamics ...

Enhanced Dielectric Constant by Al Gradient Doping on Atomic‐Layer‐Deposited HfO2‐Based Metal–Insulator–Metal Capacitor

open access: yesAdvanced Electronic Materials, Volume 12, Issue 3, 4 February 2026.
This study demonstrates that Al gradient doping significantly enhances the dielectric performance of HfO2‐based MIM capacitors compared to standard uniform Al doping. By more effectively promoting the tetragonal high‐k phase, it increases capacitance, reduces leakage current, and achieves a record‐high dielectric constant, validated across various ...
