A draw a diagram showingwhich lattice points on a graphite, Ask an Expert

Academics

a) Draw a diagram showingwhich lattice points on a graphite sheet need to be overlapped tomake the following carbon nanotubes: (5,0), (4,4) and (4,3).

b) Which of these nanotubes conducts electricity best?

c) Explain how you could generate a layered superstructure withnegatively charged buckyballs on a surface, a non-charged polyvinylchloride layer and then a positively charged dendrimerlayer on the top.

d) Electron transfer is a first-order rate process. If the rateconstant of photoinduced electron transfer from the buckyballs to the dendrimer layer in (c) is 5x108 s-1, calculate the percentage of bucky balls that will be uncharged after 0.5ns.
