Nanoscale ● Scale at which building blocks (atoms or molecules) form materials like technology ● Nanometer is 1 billionth of a meter ● So these objects have dimensions that are so small that we cannot see its structure with the human eye ● To put this into perspective: a sheet of paper is 100, 000 nm thick

What is nanotechnology? ● Tech with dimensions of less than 100 nanometers (0. 00001 meters!) ● Examples: computer circuitry, memory cards, Memory card. https: //en. wikipedia. org/wiki/Memory_card (accessed Jul 13, 2019).

Carbon ● 4 th most abundant element in the world ● Every living thing is made of carbon--like you! ● On the scale of nanometers

Carbon Allotropes ● Carbon can take on several different types of structures ● Allotrope - different physical forms that an element can exist in Graphene = carbon atom = bond that connects atoms

Carbon Allotropes = carbon atom ● Carbon can take on several different types of structures ● Allotrope - different physical forms that an element can exist in Graphene nanotubes = bond that connects atoms

Carbon Allotropes = carbon atom ● Carbon can take on several different types of structures ● Allotrope - different physical forms that an element can exist in Graphene nanotubes = bond that connects atoms Diamond
