Fig. 2From: Dedicated preparation for in situ transmission electron microscope tensile testing of exfoliated grapheneResults of liquefied gel material. a Optical image of liquefied gel material. The remaining gel is on the exfoliated graphene, whereas the rest of the gel penetrated under the exfoliated graphene. The scale bar is 20 μm. b Cross-sectional HRTEM image of gel material that penetrated under the exfoliated graphene. The scale bar is 5 nmBack to article page
