Screening of Ceramic Filler Materials for a Packed‐Bed Thermal Energy Storage System With Lead as Heat Transfer Fluid

Energy Storage, Volume 8, Issue 7, October 2026.
ABSTRACT Liquid lead (Pb) is an attractive heat transfer fluid (HTF) for packed‐bed thermal energy storage (TES) systems aimed for high temperatures. However, liquid Pb is corrosive and its corrosivity increases with rising temperature. Therefore, compatibility tests of possible filler materials with Pb are mandatory.

Ceria–zirconia mixed oxide prepared by continuous hydrothermal synthesis in supercritical water as catalyst support

, 2012
A number of different synthetic methods have been applied to prepare ceria-zirconia and related mixed oxides. Continuous hydrothermal synthesis in supercritical water (supercritical synthesis) is a method to prepare metal oxide nanoparticles rapidly and ...

Microstructure Evolution of Multi‐Material‐Jetted Porous Architectures During Ultrafast High‐Temperature Co‐Sintering

Journal of the American Ceramic Society, Volume 109, Issue 10, October 2026.
ABSTRACT Multi‐material additive manufacturing combined with rapid sintering offers a route to compositionally and microstructurally complex energy ceramic architectures, but the effect of ultrafast thermal profiles on layer retention, phase redistribution, and pore morphology remains insufficiently understood. Here, NiO–YSZ/NiO–GDC was used as an SOFC‐

Synthesis and Properties of Novel Calcia-Stabilized Zirconia (Ca-SZ) with Nano Calcium Oxide Derived from Cockle Shells and Commercial Source for Dental Application

Applied Sciences, 2020
Various oxides are used to stabilize zirconium oxide (ZrO2), but their superior hardness causes wear of the machining tool. Calcia-doped zirconia has been studied but reports on properties suitable for dental application are lacking.

The effect of ceria on the dynamics of CuO-Cu2O redox transformation: CuO-Cu2O hysteresis on ceria

, 2014
CuO supported on ceria and alumina is prepared by incipient wetness impregnation and its redox behavior is investigated by means of XRD, XPS and TPO experiments. CuO on ZrO2 and on ceria-zirconia are also synthesized for comparison.

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.

Hydrogen Production by Reforming of Methane over NiAl₂O₄/Ce_xZr_1-xO₂ Catalysts

Chemical Engineering Transactions, 2017
This work was focused on the study of the catalytic behaviour of nickel aluminate supported either on ceria or ceria-zirconia (NiAl2O4/CexZr1-xO2, x= 0.13 and 1, 14 wt.% Ni) for the steam reforming and partial oxidation of methane.
