Room-Temperature Synthesis of Soluble Carbon Nanotubes by the Sonication of Graphene Oxide Nanosheets Abstract: The transformation of two-dimensional graphene oxide (GO) nanosheets into carbon nanotubes was achieved by sonicating GO in 70% nitric acid. Through the use of mass spectrometry to t ...
图1. Schematic illustration of the creation of microfeatures on GO nanosheets with an optical microscope-focused laser beam. 图2.Optical microscope images ofthe square patterns created by laser-cutting of the 6-layer ?lm. The bright region corresponds to cut area, and dark ...
Title: Atomic layer graphene as saturable absorber for ultrafast pulsed lasers The optical conductance of monolayer graphene is defined solely by the fine structure constant, = e 2 /hc (where e is the electron charge, h is Diracs constant and ...
