The application of advanced materials in aerospace presents multiple scientific and regulatory challenges that must be addressed.
Humankind's aerospace aspirations are placing unprecedented demands on vehicle propulsion systems. Advanced structural ceramics are playing a key role in addressing these challenges.
Metallic materials are fundamental to advanced aircraft engines. While perceived as mature, emerging computational, experimental and processing innovations are expanding the scope for discovery and implementation of new metallic materials for future generations of advanced propulsion systems.
The successful adoption of metallic additive manufacturing in aviation will require investment in basic scientific understanding of the process, defining of standards and adaptive regulation.
David Rugg is the Senior Engineering Fellow in Materials at Rolls-Royce plc. He talks to Nature Materials about the need to understand scientific fundamentals to develop reliable and high-performance materials for jet engines, and the importance of university collaborations.
A rewritable platform for subwavelength optical components is demonstrated by combining surface phonon–polaritons, sustained in a polar dielectric layer, with the switching functionality provided by a phase-change material.
Titanium aluminide alloys are lightweight and have attractive properties for high-temperature applications. A new growth method that enables single-crystal production now boosts their mechanical performance.
An adsorbed polymer directs the photochemical growth of colloidal Au single-crystal nanoprisms following visible metal excitation.
Classical ionic conduction through an inorganic monolayer nanopore is analogous to the quantum-mechanical phenomenon of electronic Coulomb blockade in quantum dots.
