Folding, thinner, lighter, and stronger wings signals a quiet retreat for aluminium in aerospace

~ Matheus A. Tunes ~ Leave a comment

Airbus has just announced the next phase of its Wing of Tomorrow programme: a three-year flight-test campaign, unveiled at Farnborough, that will bolt full-scale wing extensions onto an A321neo to trial the longer, higher-aspect-ratio wings destined for the successor to its best-selling single-aisle family. The extensions are several metres long and stand in for a … Continue reading Folding, thinner, lighter, and stronger wings signals a quiet retreat for aluminium in aerospace

How much radiation damage can you do in seconds?

~ Matheus A. Tunes ~ Leave a comment

Qualifying materials for future fission and fusion reactors is painfully slow. Neutron irradiation is costly, time-consuming and leaves samples radioactive, while ion-beam alternatives require competitive proposals and scheduled beam time at oversubscribed accelerator facilities. In a new preprint, we ask whether an instrument already sitting in many microscopy labs — the plasma focused ion beam … Continue reading How much radiation damage can you do in seconds?

New recycling processes or new materials?

~ Matheus A. Tunes ~ Leave a comment

The sustainability debate in materials science sometimes asks the wrong questions. How do we recycle more aluminium & steel? These are legitimate — but they treat recyclability/sustainability as an afterthought, forcing materials never designed for circularity back into something useful at considerable cost and energy penalty: facts that Europe, specially, cannot anymore afford. The presence … Continue reading New recycling processes or new materials?

“Seeing” hydrogen embrittlement for the first time at the nanoscale

~ Matheus A. Tunes ~ Leave a comment

Hydrogen is often celebrated as the clean fuel of the future, but its relationship with metals is far more complicated than it might seem. When hydrogen atoms enter a metal, they can silently weaken it from the inside — a phenomenon known as hydrogen embrittlement — and despite being recognised for over 150 years, the … Continue reading “Seeing” hydrogen embrittlement for the first time at the nanoscale

“Zigzag Atoms: Scientists develop material with high technological potential” — The University of São Paulo

~ Matheus A. Tunes ~ Leave a comment

Our interview to the Brazilian newspaper "Jornal da USP" is now online! "Zip Phases," synthetic materials combining metallic and non-metallic chemical elements, could be used in the future in electronics, energy storage, superconductivity, and sensors. A new class of synthetic intermetallic materials, with unique atomic structures and physical properties offering high technological potential, has been … Continue reading “Zigzag Atoms: Scientists develop material with high technological potential” — The University of São Paulo
