Strong Proton‐Phonon Coupling Drives Fast Ion Transport in Perovskites

open access: yesAdvanced Science, EarlyView.
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.

Chemically Driven Nano‐Elastic Heterogeneities Control Fragility in Volcanic Melts

open access: yesAdvanced Science, EarlyView.
The study elucidates how nanoscale structural heterogeneity governs the mechanical behavior of volcanic glasses across compositions from basalt to rhyolite. Using a physicochemical framework, correlation length (ξ) and microscopic free volume (Vc) are derived from vibrational and physical properties, revealing systematic trends with silica content that

Maximal Rashba Splitting in GeTe/Bi2Te3 Heterostructures via Strong Band Bending

open access: yesAdvanced Science, EarlyView.
An unprecedented strength of Rashba effect with ER = 0.57 eV, k0=0.16Å−1$\;{k_0} = 0.16\;{\mathrm{\AA}^{ - 1}}$ and αR=6.86eV·Å$ {\alpha _{\mathrm{R}}} = 6.86{\mathrm{\;eV}} \cdot {\mathrm{\AA}}$ in GeTe (1 nm)/Bi2Te3 (1 QL) heterostructure. The enhanced Rashba is origined from the band bending effect in the heterojunction region of GeTe /Bi2Te3 ...

An Advanced High‐Performance Ultrafast Ammonium‐Ion Aqueous Battery Based on Dual‐Metal Redox Open Framework Molecular Magnet

open access: yesAdvanced Science, EarlyView.
The Prussian Blue Analogue molecular magnet KMnFeHCF is demonstrated as a high‐performance cathode for ultra‐fast aqueous ammonium‐ion batteries. A full cell using KMnFeHCF and graphite delivers ~71 mAh g−1 at 1.25 A g−1 and ~51 mAh g−1 at 2.2 A g−1, retaining 50% capacity after 1850 cycles. Its scalability, cycling stability, and low cost offer strong

Atomic‐Scale Tailoring of Ni‐Rich Cathodes for the Development of Commercial Li‐Ion Batteries: From Laboratory to Market

open access: yesAdvanced Science, EarlyView.
The growing demand in the lithium‐ion battery industry requires the efficient development of commercial batteries that approach theoretical limits within well‐established systems. In this work, we develop a strategy for controlling the voltage profile under fixed cut‐off voltages in commercial cells by utilizing Ni‐rich cathodes. We establish an atomic‐
