Strong Proton‐Phonon Coupling Drives Fast Ion Transport in Perovskites

Advanced 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

Advanced 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 ...

Atomic‐Scale Mechanisms of Multi‐Resistance States in HfOx‐Based RRAM: Evolution of Atomic Electric Fields and Oxygen Vacancies

Advanced Science, Volume 13, Issue 10, 18 February 2026.
Atomic‐scale mechanisms governing multilevel resistive switching in HfOx‐based RRAM are reveal through advanced TEM. Thermally driven m‐phase rotation ([101]↔[011]) enables selective oxygen vacancy migration, which reconstructs atomic electric fields and dictates conduction—from Schottky/Poole‐Frenkel emission to Ohmic transport.

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

Advanced 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 ...

Coupling Aqueous Phase Chemical Actinometry with EPR Spectroscopy: An Approach for Probing Photochemical Processes at the Air–Sea Interface

ChemPhysChem, Volume 27, Issue 3, February 2026.
Photochemical investigations were coupled with radical detection for quantifying oxidative processes in sea‐surface microlayer (SML) samples. A chemical actinometry approach was employed to measure photon flux in in situ EPR experiments and under solar irradiation.

Usability of Amorphous Manganese Oxide for Assessing the Proteoglycan Content in Articular Cartilage

Magnetic Resonance in Chemistry, Volume 64, Issue 2, Page 207-216, February 2026.
Amorphous manganese oxide nanoparticles exhibit high relaxivity and diffuse into articular cartilage faster than Gd‐DTPA, making them a promising agent for evaluating proteoglycan content. ABSTRACT Osteoarthritis (OA) is a highly common chronic disease that decreases functional capacity and can cause disability. The early detection of the disease could
