Solar Absorptance of Cermet Coatings Evaluated [PDF]
Cermet coatings, molecular mixtures of metal and ceramic, are being considered for the heat inlet surface of solar Stirling convertors. In this application, the key role of the cermet coating is to absorb as much of the incident solar energy as possible.

Hydrogen Permeation Properties of Ternary Ni–BaCe0.9Y0.1O3–Ce0.9Gd0.1O2 Cermet Membranes
A ternary Ni–BaCe0.9Y0.1O3 (BCY)–Ce0.9Gd0.1O2 (GDC) cermet involving 40 vol% Ni was fabricated, and its hydrogen permeation characteristics were evaluated when the GDC volume fraction was varied from 0 to 30 vol%.

Quasi‐In Situ 4D‐STEM Mapping of Exsolution Driven Parent Matrix Restructuring in Sr2FeMoO6‐δ
How does catalytic exsolution alter its parent matrix in realistic solid oxide cells? A beam‐artifact‐free, quasi‐in situ 4D‐STEM methodology maps intrinsic nanoscale transformations in bulk Sr2FeMoO6‐δ electrodes. Correlative identical‐location imaging reveals that surface exsolution inherently couples with profound crystallographic reorganization and

Cermet fuels for space power systems [PDF]
A refractory-metal matrix, UN-fueled cermet is a very promising fuel candidate for a wide range of multi-megawatt space reactor systems, e.g., steady-state, flexible duty-cycle, or bimodal, single- or two-phase liquid-metal cooled reactors, or thermionic

Ultrafast CO2 Laser Sintering of Nonwetting Alumina–Iron Ceramic–Metal Composites
ABSTRACT Alumina–iron composites are attractive for structural and functional applications but are difficult to consolidate because molten Fe poorly wets Al2O3, promoting capillary‐driven segregation during conventional liquid‐phase sintering. Here, we show that ultrafast nonequilibrium CO2 laser sintering enables rapid consolidation of this unstable ...
