Mechanistic Insights Into Proton and Oxygen Transport Through Ultrathin Amorphous Al2O3 and Al2O3‐SiO2 Electrocatalyst Overlayers

Advanced Materials Interfaces, EarlyView.
Ultrathin amorphous alumina electrocatalyst overlayers block oxygen reduction while cathodic‐driven structural relaxation accelerates proton transport over time. By contrast, ultrathin aluminosilicate coatings allow proton permeation but cannot suppress oxygen.

Self‐Organized Growth of Catalyst‐Free Single Crystal WnO3n‐2 (n = 25) Nanowire Bundles on Si (111) via Selective He+ Ion Irradiation

Advanced Materials Interfaces, EarlyView.
A novel and efficient method is explored to synthesize 1D single‐crystal sub‐stoichiometric WnO3n‐2 (n = 25) nanowire bundles. The approach utilizes selective low‐energy He+ ion irradiation (27 eV) on Mo‐Ni doped WOx surface, achieving efficient catalyst‐free self‐organized growth of high aspect ratio nanowires at the temperature of 700 °C.

Subsurface State Bilayer in Tetragonal Ferroelectric BaTiO3

Advanced Materials Interfaces, EarlyView.
The subsurface Ba2+disorder, reveals the pairs of O vacancies (VO++$V_O^{ + + }$ s) and small polarons (SPe‐SPe−$SP_e^ - $ s) (Figure a–b), with the charge balance, as the following: Ti3++[VO+++SPe−]pair↔Ti4+${{T}_i}^{3 + } + {{[V_O^{ + + } + SP_e^ - ]}_{pair}} \leftrightarrow T_i^{4 + }$ which is consistent with observed low‐energy electron ...
