Surface‐Anchored Microgel‐Based Films as Anti‐Icing Coatings

Advanced Materials Interfaces, EarlyView.
The microgel‐based anti‐icing coatings presented in this work reduce ice adhesion by up to 90% on various substrates. This effect can be attributed to the incorporated functional cationic moieties binding a lubricating layer of quasi‐liquid interfacial water.

The Effect of the Purge–Mainstream Density Ratio on Rim Seal Fluid Mechanics

International Journal of Turbomachinery, Propulsion and Power
Significant density ratios arise in a gas turbine due to severe temperature gradients between the hot mainstream gases leaving the combustor and the superposed purge flow injected from the secondary air system. Engineers seek to minimise the ingestion of
