Insect contamination protection for laminar flow surfaces [PDF]

open access: yes
The ability of modern aircraft surfaces to achieve laminar flow was well-accepted in recent years. Obtaining the maximum benefit of laminar flow for aircraft drag reduction requires maintaining minimum leading-edge contamination.

Shape optimisation of electro-mechanical ice protection systems

open access: yes, 2021
The ice protection system (IPS) is one of the major consumers among the non-propulsive systems of an aircraft. In the trend of the electrification of the aircraft systems to minimize air transport environmental impact, this article focuses on electromechanical IPS which could be a low power alternative to electro-thermal ice protection systems.

Bio‐Inspired Molecular Events in Poly(Ionic Liquids)

open access: yesAdvanced Functional Materials, EarlyView.
Originating from dipolar and polar inter‐ and intra‐chain interactions of the building blocks, the topologies and morphologies of poly(ionic liquids) (PIL) govern their nano‐ and micro‐processibility. Modulating the interactions of cation‐anion pairs with aliphatic dipolar components enables the tunability of properties, facilitated by “bottom‐up ...

First characterization of the marine ecosystem of Archer Fiord in the Lasting Ice Area of the High Arctic: a productivity paradox

open access: yesArctic Science
The Lasting Ice Area along the northern coastline of Ellesmere Island and Greenland will be the region where Arctic multiyear sea ice will persist the longest in a warming climate, making this area critical for ice-dependent species.

Fluorine‐Free Soft Nanocomposites for High‐Speed Liquid Impact Repellence

open access: yesAdvanced Functional Materials, EarlyView.
Fluorine‐free soft nanocomposite coatings are developed using silicone oil‐mediated mechanical‐stiffness control, enabling ‘dry’ liquid‐repellent surfaces that resist high‐speed water jet impacts up to ∼60 m/s. By tuning nanoparticle loading and oil content, the coatings also achieve >90% optical transparency, amphiphobicity with impact resistance to ...
