2.  Rollable E-Paper  Transistors  Super-capacitors (batteries that can store incredible amounts of charge.  Flexible Touch Screens  Space Elevator

4.  An allotrope of carbon that is a single layer thick.  Has incredible electronic, optical, and physical properties  Ideal candidate for the aforementioned applications  Sir Konstantin Novoselov and Sir Andre Geim: awarded the Nobel Prize for their “ground breaking experiments on the two dimensional material”

5. Puja Trivedi, Sophomore, GT Independent Research

6. Today, I will go over  Graphene’s properties  Importance in science  Methods of Production ▪ Chemical Vapor Deposition ▪ Mechanical Exfoliation ▪ Dip-Pen Lithography  My Primary Research

7.  Honeycomb Lattice Offers Unique Properties  Able to “self-repair”: can be fixed when it is exposed to hydrocarbons, and pure carbon atoms.  High electron mobility  Super-conductor  Incredibly light  Strongest material

8.  Relatively dense  Fast reaction to light  Absorbs 3% of light

9.  Difficult to Mass Produce  Expensive  Fragile  Highly specialized  Environmentally harsh  Lacks compatibility with silicon carbide electronics (current system)

10.  Consulted several websites specializing on graphene  NanoHub  Nature Nanotechnology  iTunes U  Nanowerk  Interviewed experts: Dr. Rebecca McNaughton, and Dr. Theodosia Gougousi

11.  Analyzed how useful the websites are.  Content  Design  Navigation  Cost  Audience  Looked for characteristics that I would like to include in my website

13.  Chemical Vapor Deposition  Mechanical Exfoliation  Dip-pen Lithography, including the Nanofountain Probe www.mechanicalengineeringblog.com

14.  Used by Sir Andre Geim and Sir Konstantin Novoselov to research graphene.  Involves separating individual sheets of graphite from a large block  Uses an adhesive or a ball-mill, which separates the graphite  Used for moderate to low quality applications of graphene, (filler, inks etc) University of Manchester

15. IInvolves high temperatures (1000 C) to cure react the methane, and substrate PProduces high quality graphene (electronics)  Relatively expensive  Careful set-up and execution  Environmentally harsh

16.  Uses cantilevers to print “ink” onto a substrate, which will then be cured using CVD  Generally, executed with a single probe that requires refilling every so often  Slow but high quality  May eventually be used to print patterns Northwestern University

17. The NFP is the best method for high-quality, large scale graphene manufacturing.  Faster  More Accurate  Easier to scale  Can potentially be integrated into the silicon ideas 300 × 269 - clifton.mech.northwe stern.edu

18.  Created a website that discusses  Different types of production methods  Overview of Graphene  Important Figures in Graphene Research  http://massproductionofgraphene.weebly.com http://massproductionofgraphene.weebly.com  Check it out!

20.  What have you learned?  What Graphene is.  How it is Created  Best Method for Mass Production  Why it is Important to Research Graphene
