The synthesis of these materials was carried out in a closed Hastelloy\u00ae reactor at 700 \u00b0C. The treatment, during which autogenic pressure was generated, leads to highly graphitic materials with stunning properties, particularly concerning the oxidation resistance (compared to the graphite stability). The metallic doping triggers the growth of nanostructures with diverse morphologies around the spheres, obtaining samples with magnetic properties.<\/jats:p>","DOI":"10.3390\/nano9040606","type":"journal-article","created":{"date-parts":[[2019,4,12]],"date-time":"2019-04-12T12:55:04Z","timestamp":1555073704000},"page":"606","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["From Polyethylene to Highly Graphitic and Magnetic Carbon Spheres Nanocomposites: Carbonization under Pressure"],"prefix":"10.3390","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2799-1866","authenticated-orcid":false,"given":"Jesica","family":"Castelo-Quib\u00e9n","sequence":"first","affiliation":[{"name":"Carbon Materials Research Group, Department of Inorganic Chemistry, Faculty of Sciences, University of Granada, Campus Fuentenueva s\/n, ES18071-Granada, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7037-3417","authenticated-orcid":false,"given":"Luisa M.","family":"Pastrana-Mart\u00ednez","sequence":"additional","affiliation":[{"name":"Carbon Materials Research Group, Department of Inorganic Chemistry, Faculty of Sciences, University of Granada, Campus Fuentenueva s\/n, ES18071-Granada, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2516-7806","authenticated-orcid":false,"given":"Francisco","family":"Carrasco-Mar\u00edn","sequence":"additional","affiliation":[{"name":"Carbon Materials Research Group, Department of Inorganic Chemistry, Faculty of Sciences, University of Granada, Campus Fuentenueva s\/n, ES18071-Granada, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1483-0035","authenticated-orcid":false,"given":"Agust\u00edn F.","family":"P\u00e9rez-Cadenas","sequence":"additional","affiliation":[{"name":"Carbon Materials Research Group, Department of Inorganic Chemistry, Faculty of Sciences, University of Granada, Campus Fuentenueva s\/n, ES18071-Granada, Spain"}]}],"member":"1968","published-online":{"date-parts":[[2019,4,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"455","DOI":"10.1016\/j.carbon.2004.10.022","article-title":"Carbon aerogels for catalysis applications: An overview","volume":"43","year":"2005","journal-title":"Carbon"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"131","DOI":"10.1007\/s13726-011-0011-0","article-title":"Chemical synthesis and characterization of self-doped N-propanesulfonic acid polyaniline derivatives","volume":"21","author":"Grigoras","year":"2012","journal-title":"Iran.
