substance PET (polyethylene terephthalate) as it has a good balance between carbon, hydrogen and oxygen to simulate the interior of ice giant planets.<\/p>\n<p>The experiment was conducted at California\u2019s SLAC National Accelerator Laboratory, using the Linac Coherent Light Source (LCLS), a powerful, accelerator-based X-ray laser.<\/p>\n<p>Two measurement methods were used to analyse what happened when the intensive laser flashes hit the film. These were X-ray diffraction, which determined whether nanodiamonds were produced, alongside a small-angle scattering (SAS) technique, to see how quickly and how large the nanodiamonds grew.<\/p>\n<p>This research further supports the theory that on ice giants such as Neptune and Uranus, it could literally rain diamonds. Similar planets outside of our Solar System could also experience this sort of activity.<\/p>\n<p><strong>Read more about the ice giants:<\/strong><\/p>\n<ul><li><a href=\"&quot;https:\/\/www.sciencefocus.com\/space\/who-really-discovered-neptune\/&quot;\">Who really discovered Neptune?<\/a><\/li>\n<li><a href=\"&quot;https:\/\/www.sciencefocus.com\/space\/why-does-uranus-orbit-the-sun-on-its-side\/&quot;\">Why does Uranus orbit the Sun on its side?<\/a><\/li>\n<\/ul><p>The scientists believe that an unusual form of water known as \u2018superionic water\u2019 should be produced alongside the diamonds, and they want to carry out further research to confirm whether or not this is the case.<\/p>\n<p>In addition to providing this exciting new knowledge about the ice giant planets, the research could also help establish a new way of producing nanodiamonds in industry, where they can be used, for example, in the production of quantum sensors. It could also help with the tailored production of nanometer-sized diamonds, which are currently used in the manufacture of abrasives and polishing agents.<\/p>\n<p>\u201cSo far, diamonds of this kind have mainly been produced by detonating explosives,\u201d said Kraus. \u201cWith the help of laser flashes, they could be manufactured more cleanly in the future. The X-ray laser means we have a lab tool that can precisely control the diamonds\u2019 growth.\u201d<\/p><\/body><\/html>\n<hr class=\"no-tts wp-block-separator\"\/>","protected":false},"excerpt":{"rendered":"<p>By Neil McKim Published: Friday, 02 September 2022 at 12:00 am A team of German and French researchers have designed an intriguing experiment in order to find out more about the conditions in the ice giant planets, Neptune and Uranus.
