Nanotechnology Course - Lesson 03 - Introduction to Graphene Catch up on previous lessons! https://youtube.com/playlist?list=PLILWudw_84t0wywDskiddP6b_G8hCi4eZ&si=toHdkcqnyZJ-6t2T Graphene Structure and Properties: Graphene is a single sheet of graphite, with less than 10 layers considered graphene and more than 10 considered graphite. Graphene's properties change with the number of layers and their alignment. Graphene Production Methods: Several methods to produce graphene include liquid exfoliation, oxidation, growth on silicon carbide, and chemical vapor deposition. Each method has varying yields and quality of graphene. Authentication with Graphene Markers: Dr. James Tour discusses using graphene markers to authenticate high-end products like purses and shoes by embedding markers that can be detected via a smartphone. Electronic Properties and Potential: Graphene and carbon nanotubes exhibit high electronic mobility, theoretically up to a million cm²/Vs, which could significantly speed up computing processes. Commercial and Research Applications: Graphene's diverse applications include transparent conductive films, deicing surfaces, enhancing plastic bottle performance, and potential use in spinal cord injury treatment. Research also explores producing graphene from various carbon sources. --- If you would like to support us in creating more content across our different media platforms, we would greatly appreciate any support you can give.
