A new laser machining method that dynamically adapts its beam shape is proposed to fabricate microgrooves with complex, highly precise cross-sections - some with a root mean square error decreased to less than 0.5 micron.
Researchers demonstrate a low-cost, scalable and reusable catalyst to produce an alternative to traditional jet fuel, demonstrating the first production of sustainable aviation fuel from food waste-derived biocrude using non-noble metal carbide catalysts.
New research into the anatomy of blue sharks reveals a unique nanostructure in their skin that produces their iconic blue colouration, but intriguingly, also suggests a potential capacity for colour change.
