Heat Transfer Through Plasma-Sprayed Thermal Barrier Coatings in Gas Turbines: A Review of Recent Work

, 2009
A review is presented of how heat transfer takes place in plasma-sprayed (zirconia-based) thermal barrier coatings (TBCs) during operation of gas turbines. These characteristics of TBCs are naturally of central importance to their function. Current state-

Sol–gel processing and characterization of (RE-Y)-zirconia powders for thermal barrier coatings [PDF]

, 2011
The effect of doping on the structural, morphological and thermal properties of ZrO2–XO1.5 (X=Y, La, Sm, Er) solid solutions for thermal barrier (TBC) applications was investigated. Oxide powders of various compositions from 9.7 to 40 mol% XO1.5 (X=Y, La,

A nacre formation-inspired dynamic self-generating barrier for environmental deposit-resistant thermal barrier coatings

Journal of Advanced Ceramics
To address the challenge of corrosion in thermal barrier coatings (TBCs) by low-calcium-silica-ratio, impurity-containing environmental deposits (CMAS-E) in advanced aeroengines, this study, inspired by the adaptive defense mechanism of nacre formation ...

High-entropy perovskite RETa3O9 ceramics for high-temperature environmental/thermal barrier coatings

Journal of Advanced Ceramics, 2022
Four high-entropy perovskite (HEP) RETa3O9 samples were fabricated via a spark plasma sintering (SPS) method, and the corresponding thermophysical properties and underlying mechanisms were investigated for environmental/thermal barrier coating (E/TBC ...

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

FEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

(Lu1/7Yb1/7Sc1/7Er1/7Y1/7Ho1/7Dy1/7)2Si2O7 high entropy rare-earth disilicate with low thermal conductivity and excellent resistance to CMAS corrosion

Journal of Advanced Ceramics
Low thermal conductivity, compatible thermal expansion coefficient, and good calcium–magnesium–aluminosilicate (CMAS) corrosion resistance are critical requirements for environmental barrier coatings used on silicon-based ceramics.

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential

FEBS Letters, EarlyView.
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.
