Universal In Situ Isotope Exchange Raman Spectroscopy (IERS) Methodology for Measuring Oxygen Surface Exchange Dynamics Using a Probe Layer

open access: yesAdvanced Functional Materials, Volume 36, Issue 17, 26 February 2026.
A bespoke multilayer thin film configuration has been designed, which overcomes the material dependency of conventional isotope exchange Raman spectroscopy (IERS). This universal IERS methodology is efficient, non‐destructive and provides additional structural information and time resolution, which can be further extended to various isotopic elements ...

Grain Boundary Space Charge Engineering of Solid Oxide Electrolytes: Model Thin Film Study

open access: yesAdvanced Functional Materials, Volume 36, Issue 14, 16 February 2026.
This study demonstrates unprecedented control of grain boundary electrical properties in solid electrolytes. Selective diffusion of cations through grain boundaries in thin films enables 12 orders of magnitude variation in ionic resistance, proving that systematic chemical modification of grain boundary electrical properties is feasible.

Reverse Water Gas Shift Reaction Assisted by Electric Field Over Ce‐ and Zr‐Based Materials

open access: yesChemCatChem, Volume 18, Issue 4, 25 February 2026.
The production of CO through CO2 reduction via the reverse water gas shift reaction in electric field was investigated over NiO, Ni deposited CeO2, ZrO2 and Ce0,5Zr0,5O2. Some cerium‐based catalysts produced CH4 + CO, but the addition of Zr led toward only CO.

Effects of B‐Site Nb Substitution on ORR Activity in Perovskite Cathode Materials for Solid Oxide Fuel Cells

open access: yesSusMat, Volume 6, Issue 1, February 2026.
B‐site Nb substitution in PSCF perovskite cathodes modulates oxygen vacancy formation and electronic structure, thereby tailoring oxygen adsorption and ion transport properties. A moderate Nb level (5–10%) optimizes the balance between surface activity and conductivity, enhancing ORR kinetics and SOFC performance. ABSTRACT Solid oxide fuel cells (SOFCs)

Catastrophic Degradation in Solid Oxide Fuel Cells Caused by Air Supply Interruption in Real‐World Operations: Fundamental Mechanisms and Mitigation Strategies

open access: yesAdvanced Science, Volume 13, Issue 3, 14 January 2026.
Interrupting the air supply during the operation of solid oxide fuel cells leads to irreversible chemical degradation of the cathode materials, primarily driven by strontium at the A‐site of perovskite structures. Alternative strontium‐free materials effectively address this issue, ensuring high performance and reliable operation during operational ...

Comparison of Surface Features of Ceramic and Ti‐Based Dental Implants

open access: yesphysica status solidi (a), Volume 223, Issue 2, January 2026.
The roughness values of ceramic implants are slightly higher than of the titanium machined sample and significantly lower than of sandblasted implants. The observed structures, along with the roughness values, could enhance the osseointegration of the 3D printed ceramic implants.
