Unveiling the Aging Effect at the Interface of N719 Dye‐Sensitized Solar Cells

open access: yesAdvanced Materials Interfaces, EarlyView.
Iodide is incorporated into the N719 layer through two mechanisms: the known ligand exchange of NCS with I and a second yet unknown mechanism which significantly blocks the charge regeneration process of the N719 dye contributing to the cell degradation.

Ag‐Cu Nanoarchitecture for Enhanced LSPR Absorption: the Role of Surface Roughness and near‐field Interactions

open access: yesAdvanced Materials Interfaces, EarlyView.
This study investigates the plasmonic properties and biosensing capabilities of a nanocomposite incorporating Cu and Ag nanoparticles for detecting anti‐DbpA antibodies associated with Lyme disease. The enhanced LSPR response is explained through FDTD simulations of Cu–Ag near‐field interactions and increased surface roughness.

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.

Stress Response of Aspergillus niger Spores to Copper Surfaces and the Implications for Antifungal Surface Functionalization

open access: yesAdvanced Materials Interfaces, EarlyView.
This study investigates the antifungal efficacy of ultrashort pulsed laser‐induced periodic surface structures (USP‐DLIP) on copper, brass, and steel surfaces. Using Aspergillus niger as a model, the research highlights a 99% reduction in spore viability on 9 µm structured copper surfaces due to enhanced copper ion release. Scanning electron microscopy
