source:KeAi Communications Co.The hot-end components of high-performance high-speed aircraft need to meet performance requirements such as long service life, wide temperature range oxidation resistance and ablation resistance. This puts forward higher requirements for high-temperature service performance of thermal protection system (TPS).With low density, low expansion and excellent high temperature mechanical properties, carbon-carbon (C/C) composites are expected to be the best choice for the new generation of TPS. However, the oxidation sensitivity of C/C composites severely limits their s...

source:the armchair traderThe spotlight often falls on renewable technologies like solar panels and wind turbines in the quest for a sustainable and clean energy future. However, the true heroes behind these innovations are the materials that make them possible.Iridium and rare-earth elements (REEs) play a crucial, albeit less talked about, role in this transition.Iridium, a member of the platinum group metals, is essential for the efficiency of hydrogen fuel cells and electrolysers. Meanwhile, rare-earth elements, despite their name, are relatively abundant and are vital in manufacturing high...

source:physics worldResearchers at Princeton University in the US have made a key step towards realizing scalable quantum networks thanks to a rare-earth element: erbium. Erbium is good at emitting and absorbing photons at wavelengths used in the telecommunications industry, which is an advantage because these photons can travel long distances with little attenuation in standard optical fibres. Harnessing this strength in the quantum realm has been a challenge, but the Princeton team managed to coax an erbium-based device into emitting identical photons – a prerequisite for quantum repeaters t...
