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

open access: yesAdvanced 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.

Sol–Gel Thin Films for the Protection of Ancient Glass Artifacts: A Performance Comparison Between Inorganic and Hybrid Silica Compositions

open access: yesAdvanced Materials Interfaces, EarlyView.
This study explores the development of sol–gel coatings for archaeological glass conservation. By formulating silica‐based solutions with low acid concentrations and applying them via dip coating, protective films are prepared at room temperature. Analysis reveals that hybrid coatings with methyl and octyl groups provide superior protection against ...

Supramolecular Nanoarchitectonics of PNIPAAM‐co‐MA and Imogolite to Obtain Thermoresponsive Clay Nanotubes Through Complexation Mechanism

open access: yesAdvanced Materials Interfaces, EarlyView.
The selective adsorption of anionic poly(N‐isopropylacrylamide)‐co‐methacrylic (PNIPAAM‐co‐MA) onto the external surface of imogolite nanotubes is driven by electrostatic attractions. The copolymer coating affects the surface charge, aqueous diffusion and self‐assembling of imogolite.
