We show here a 3D analysis of the nanostructuration of few-layer graphene by iron-based nanoparticles under hydrogen flow. The nanoparticles located at the edges or attached to the steps on the FLG sheets create trenches and tunnels with orientations, lengths and morphologies defined by the crystallography and the topography of the carbon substrate. The cross-sectional analysis of the 3D volumes highlights the role of the active nanoparticle identity on the trench size and shape, with emphasis on the topographical stability of the basal planes within the resulting trenches and channels, no matter the obstacle encountered. The actual study gives a deep insight on the impact of nanoparticles morphology and support topography on the 3D character of nanostructures built up by catalytic cutting. 000063149 536__ $$9info:eu-repo/grantAgreement/EC/FP7/312483/EU/Enabling Science and Technology through European Electron Microscopy/ESTEEM 2$$9info:eu-repo/grantAgreement/EC/FP7/280658/EU/Doped carbon nanostructures as metal-free catalysts/FREECATS 000063149 540__ $$9info:eu-repo/semantics/openAccess$$aby-nc-nd$$uhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/ 000063149 590__ $$a11.47$$b2014 000063149 591__ $$aMULTIDISCIPLINARY SCIENCES$$b3 / 57 = 0.053$$c2014$$dQ1$$eT1 000063149 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000063149 700__ $$aFlorea, I. 000063149 700__ $$aMoldovan, S. 000063149 700__ $$aJanowska, I. 000063149 700__ $$aBaaziz, W. 000063149 700__ $$0(orcid)0000-0002-2071-9093$$aArenal, R. 000063149 700__ $$aWisnet, A. 000063149 700__ $$aScheu, C. 000063149 700__ $$aBegin-Colin, S. 000063149 700__ $$aBegin, D. 000063149 700__ $$aPham-Huu, C. 000063149 700__ $$aErsen, O. 000063149 773__ $$g5 (2014), 4109 [8 pp]$$pNATURE COMMUNICATIONS$$tNature Communications$$x2041-1723 000063149 8564_ $$s2520230$$uhttps://zaguan.unizar.es/record/63149/files/texto_completo.pdf$$yVersión publicada 000063149 8564_ $$s63572$$uhttps://zaguan.unizar.es/record/63149/files/texto_completo.jpg?subformat=icon$$xicon$$yVersión publicada 000063149 909CO $$ooai:zaguan.unizar.es:63149$$particulos$$pdriver 000063149 951__ $$a2019-05-29-11:40:02 000063149 980__ $$aARTICLE
