Permeation of chemisorbed hydrogen through graphene: A flipping mechanism elucidated

Marcelo Castellanos2022-04-05T17:41:09+02:00Tags: Chemistry, Multidisciplinary. , Physical; Materials Science|

Authors: Bartolomei, Massimiliano; Hernandez, Marta, I; Campos-Martinez, Jose; Hernandez-Lamoneda, Ramon; Giorgi, Giacomo Journal: CARBON Publication date: 2021/06/30 DOI: 10.1016/j.carbon.2021.02.056 Abstract: The impermeability of defect-free graphene to all gases has been recently contested since experimental evidence (see Nature 579, 229-232 (2020)) of hydrogen transmission through a two-dimensional carbon layer has been obtained. By means of density [...]

Graphene multi-protonation: A cooperative mechanism for proton permeation

Marcelo Castellanos2020-01-16T12:54:25+01:00Tags: Chemistry, Multidisciplinary. , Physical; Materials Science|

Authors: Bartolomei, Massimiliano; Hernandez, Marta, I; Campos-Martinez, Jose; Hernandez-Lamoneda, Ramon Contribution: Article Journal: CARBON Publication date: 2019/04/07 DOI: 10.1016/j.carbon.2018.12.086 Abstract: The interaction between protons and graphene is attracting a large interest due to recent experiments showing that these charged species permeate through the 2D material following a low barrier (similar to 0.8 eV) activated process. A [...]
