Materials coloured like a peacock

Melanin-like compounds can be precisely designed and arranged to colour materials using a mechanism similar to that found in a peacock’s feathers. Chemist Michinari Kohri of Chiba University in Japan reviewed the latest research on these ‘melanin-mimetic…

Micropillar compression for finding heat-tolerant alloys

Accurate measurements of crystalline deformation should help engineer stronger components for more energy-efficient turbines. Metals containing niobium silicide are promising materials that can withstand high temperatures and improve efficiency of gas turbines in power plants…
