Gas phase synthesis of gold and silver nanostructured films for secondary electron emission mitigation

Q: What does this research mean for the field?

Porous gold and silver nanoparticle coatings produced via gas phase synthesis exhibit lower secondary electron yield and higher predicted multipactor breakdown threshold voltages compared to standard Alodine conversion coatings, with these properties remaining stable after annealing. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.
