This week, the GET\u00ae team, in cooperation with Poznan University of Technology \u00a0and the National Centre for Nuclear Research, published on the discovery of a self-healing effect in electronic-grade graphene on silicon carbide exposed to fast-neutron radiation.<\/p>\n<p>The radiation knocks out atoms from a hydrogen cushion below the graphene layer and degrades graphene\u2019s quasi-free-standing character. Yet, a temperature trigger that fits perfectly within the operational limits of the platform can redistribute the remaining population of hydrogen atoms and restore graphene\u2019s properties.<\/p>\n<p>The damage caused to graphene by neutron radiation can be likened to the loss of protective layers observed in lizard skin.\u00a0 In both cases, the removal of a structural component leads to a loss of functionality. However, similar to the regenerative capacity of lizards, graphene demonstrates a remarkable ability for self-healing. This capability is evident in graphene\u2019s ability to restore its structural integrity when heated to a specific temperature, enabling the hydrogen atoms that support its structure to reattach and recover the material\u2019s original properties.<\/p>\n<p>This finding may pave the way for magnetic field sensors with a continuous self-healing effect, expanding the boundaries of graphene applications in neutron-exposed environments.<\/p>\n<p>GET\u00ae is at the forefront of materials science for affordable and clean energy.\u00a0 Efforts have been undertaken to design materials capable of withstanding high temperatures and neutron radiation. Such platforms will enable magnetic diagnostics in extreme environmental conditions, such as those in future thermonuclear reactors.<\/p>\n<p>The Polish nuclear energy sector is gaining significant attention from policymakers as new strategic programs are being developed by the National Centre for Research and Development.<br \/>\nDetails of this discovery have been published in Open Access form in Elsevier Applied Surface Science.<\/p>\n<p>You can learn more at <a href=\"https:\/\/www.researchgate.net\/publication\/386400141_Fluence_and_thermal_threshold_for_an_effective_self-healing_in_high-energy-neutron-irradiated_Al2O3QFS-graphene6H-SiC0001_system\">https:\/\/www.researchgate.net\/publication\/386400141_Fluence_and_thermal_threshold_for_an_effective_self-healing_in_high-energy-neutron-irradiated_Al2O3QFS-graphene6H-SiC0001_system\u00a0<\/a><\/p>\n<\/div><\/div><\/div><\/div><\/div>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":24,"featured_media":20268,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_seopress_robots_primary_cat":"none","_seopress_titles_title":"","_seopress_titles_desc":"","_seopress_robots_index":"","_lmt_disableupdate":"no","_lmt_disable":""},"categories":[86,196],"tags":[1457,1458,1459],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v19.13 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Neutron-damaged graphene can heal itself - \u0141ukasiewicz \u2013 IMiF<\/title>\n<meta name=\"description\" content=\"Neutron-damaged graphene can heal itself \u2013 a discovery by Polish scientists.
