Local structure investigation in ceria-zirconia "k -phase" by XAFS: unraveling the reason for outstanding oxygen storage capacity

, 2015
Ceria zirconia solid solutions (CexZryO2, CZ) are well known for buffering oxygen due to fast and easy switch between the oxidation states Ce3+/Ce4+ [1], showing remarkable oxygen storage capacity (OSC), and, thanks to the presence of the zirconium ...

Chemical Control of Space Charge Barriers and Grain Boundary Resistances in Polycrystalline Ionic Conductors

Advanced Functional Materials, Volume 36, Issue 74, 14 September 2026.
Grain boundaries (GBs) in polycrystalline materials often block charge transport and drive degradation. Using Gd‐doped CeO2 as a model electrolyte used in fuel/electrolysis cells, we developed a core‐shell infiltration method to selectively modify GB chemistry and space charge potential, achieving orders‐of‐magnitude ionic conductivity changes.

Tuning Amorphous‐Crystalline Catalytic Interfaces by Mechanochemistry: Cu‐Based Metallic Glasses Coupled with Ceria for CO Oxidation

Advanced Materials, Volume 38, Issue 51, 11 September 2026.
Ball‐milling Cu‐based metallic glasses with ceria creates a unique nanostructure where metallic glass particles are wrapped by CeO2 nanoparticles. The intimate integration triggers copper state reorganization during reaction and aging, boosting CO oxidation and COPrOx activity.

Engineered Au@CeO2 Hybrid Nanoparticles With Microenvironment Dependent Self‐Adjustability for Integration of Tumor‐Specific Photothermal‐Chemodynamic Therapy and Inflammation Prevention

Advanced Science, Volume 13, Issue 51, 14 September 2026.
An intelligent Au@CeO2 Hybrid Nanoparticles (ACEF) with microenvironment‐dependent self‐adjustability was engineered to not only perform efficient and tumor‐specific photothermal‐chemodynamic therapy for precise tumor elimination, but also serve as a ROS scavenger in healthy tissues around the tumor to avoid the unexpected oxidative damage and ...

Amorphous, Highly Conductive Pr0.7Ca0.3MnO3 for Area‐Dependent Resistive Switching AlOx Bilayer Devices

Advanced Electronic Materials, Volume 12, Issue 17, 7 September 2026.
High‐conductive amorphous Pr0.7Ca0.3MnO3 (PCMO) is explored as an alternative to polycrystalline PCMO for memristive heterostructures with back‐end‐of‐line compatibility, targeting neuromorphic hardware integration. Structural, electrical, and band alignment analyzes are correlated with the electrical characterization of area‐dependent resistive ...

High Power Density, Low Temperature, Solid Oxide Fuel Cells at Elevated Oxygen Partial Pressure

Advanced Energy Materials, Volume 16, Issue 33, 2 September 2026.
Elevated pO2${{p}_{{{{\mathrm{O}}}_2}}}$ improves oxygen reduction reaction (ORR) kinetics, thus reducing electrode area specific resistance (ASR). The effect of pO2${{p}_{{{{\mathrm{O}}}_2}}}$ in open circuit potential (OCP) and ASR is demonstrated on both Sr0.5Sm0.5CoO3‐δ‐Gd0.1Ce0.9O2‐δ (SSC‐GDC) composite cathodes and our recently developed nano‐PSC

Towards a Gröbner-free approach to coding

Recently, new studies on the decoding of cyclic codes have been developed. They place themselves under the umbrella of Cooper Philosophy and they consist in using (sparse) locator polynomials, which, once evaluated at the syndromes, return the error ...
