New study reveals unexpected softness of bilayer graphene

30 April 2020

In the study, published in the journal Physical Review B, the researchers showed that bilayer graphene, consisting of two layers of graphene, was noticeably softer than both two-dimensional (2D) graphene and three-dimensional (3D) graphite along the stacking direction. This surprising result differs from previous research which showed that 2D graphene, ... [more]

Graphene is 3D as well as 2D

25 September 2019

Graphene is actually a 3D material as well as a 2D material, according to a new study from Queen Mary University of London. Realising that it is a 3D material is important for understanding its mechanical properties and for developing novel graphene-based devices. Often hailed as a ‘wonder material’, graphene ... [more]

Properties of ‘wonder material’ graphene change in humid conditions

21 January 2019

Graphene exhibits very different properties in humid conditions, according to researchers from Queen Mary University of London. The ‘wonder material’, which is made from carbon and was discovered in 2004, is hailed for many of its extraordinary characteristics including being stronger than steel, more conductive than copper, light, flexible and transparent. ...
