Iron‐Based Catalysts on Tailored Alumina Supports for COx‐Free Methane Decomposition to H2 and Carbon

ChemistryOpen, Volume 15, Issue 9, September 2026.
Fe‐10ZrAl catalyst enables catalytic methane decomposition into COx‐free H2 and solid carbon. ZrO2‐modified alumina improves Fe particle stabilization, reducibility, and carbon growth behavior, giving the best performance among the tested catalysts with 76.5% CH4 conversion and 74.1% H2 yield at 800 °C.

Y2O3‐Doped Bi2O3–Y2O3‐Stabilized ZrO2 Composite Ceramic Electrolytes Fabricated by Infiltration

Journal of the American Ceramic Society, Volume 109, Issue 9, September 2026.
To boost the electrical conductivity of solid oxide cell electrolytes, Y2O3–stabilized ZrO2 (YSZ) is mixed with Y2O3–doped Bi2O3 (YDB). Alternative to mixing and co‐sintering of powders, infiltration of liquid YDB precursor into porous YSZ scaffold is proposed.

High‐Temperature Evolution of a Core–Shell TBC: Linking Microstructure to CMAS, Sintering, and Fracture Resistance

Journal of the American Ceramic Society, Volume 109, Issue 9, September 2026.
This graphical abstract summarizes the key findings on the high‐temperature evolution of a core‐shell thermal barrier coating (TBC). Upon annealing, alumina redistribution remains confined to the shell region. The core‐shell TBC demonstrates superior retention of CMAS resistance, sintering resistance, and fracture toughness compared to the benchmark ...

Influence of Different Multilayer Zirconia Materials on the In Vitro Load‐Bearing Capacity of Resin‐Bonded Fixed Partial Dentures in the Posterior Region

Journal of Esthetic and Restorative Dentistry, Volume 38, Issue 9, Page 1854-1863, September 2026.
ABSTRACT Objective Comparison of the load‐bearing capacity and failure pattern of posterior resin‐bonded fixed partial dentures (RBFPDs) differing in retainer design, zirconia material, and vertical nesting position. Materials and Methods RBFPDs replacing a maxillary first molar were fabricated with 2 retainer designs (inlay‐retained, IR; wing‐retained,
