Graphene is a sheet of carbon atoms organized in a hexagonal lattice. 3D graphene, which is produced when layers of graphene are bonded by plasma welding, is lighter than titanium, a material used in prostheses. \u201cThe idea was to create 3D graphene using 2D pieces,\u201d says Douglas Galv\u00e3o, professor at the University of Campinas (Unicamp). He and post-doctoral fellows Pedro Autreto, of the Federal University of the ABC (UFABC), and Cristiano Woellner, of Unicamp, took part in developing this configuration of graphene oxide, along with researchers from Rice University and the University of Texas, in the United States, and the International Advanced Research Centre for Powder Metallurgy and New Materials (ARCI), in India. \u201cThe material now resembles porous cork,\u201d explains Galv\u00e3o. \u201cIts high porosity is important because nanoscale roughness enhances integration with body cells.\u201d The work of the Brazilian team was funded by the Center for Computational Engineering and Sciences (CCES), one of FAPESP\u2019s Research, Innovation and Dissemination Centers (RIDC).<\/p>\n","protected":false},"excerpt":{"rendered":"Features of graphene may potentially be utilized in bone implants","protected":false},"author":475,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_exactmetrics_skip_tracking":false,"_exactmetrics_sitenote_active":false,"_exactmetrics_sitenote_note":"","_exactmetrics_sitenote_category":0,"footnotes":""},"categories":[168],"tags":[259,243,247],"coauthors":[785],"class_list":["post-235221","post","type-post","status-publish","format-standard","hentry","category-technoscience","tag-chemistry","tag-innovation","tag-medicine"],"acf":[],"_links":{"self":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/235221","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/users\/475"}],"replies":[{"embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/comments?post=235221"}],"version-history":[{"count":0,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/235221\/revisions"}],"wp:attachment":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/media?parent=235221"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/categories?post=235221"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/tags?post=235221"},{"taxonomy":"author","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/coauthors?post=235221"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
