Making C60, soot, stars and the DIBs: past: Harry Kroto and Jonathan Hare

Dr Jonathan Hare and Sir Harry Kroto chat about the discovery of C60 and the fullerenes and the exciting times when they were made for the first time.


C60 and Soot: Harry Kroto and Jonathan Hare

Dr Jonathan Hare talks with Sir Harry Kroto about C60 and soot formation. One of Michael Faradays classic works (a chemical history of a candle) was about the candle and its sooting flame, could Faraday have made C60?

Longboard Part 1 - A skateboard speedometer

We describe an electronic speedometer that can be built to measure the speed of a skateboard, longboard or even a bike. We look at two methods to detect the rotation of a wheel (Infrared and magnetic) to determine the speed.

Keywords: Speed, skateboarding, longboarding, speedometer, electronics, 555 timer chip

More information at: Homemade Speedometer - Creative Science Centre website..


Longboard Part 2 - Some Physics of skateboarding

If you are cycling or skateboarding along at 10 miles per hour what is the speed on the top and bottom of your wheels? The answers are 20 miles per hour and zero which is at first a bit puzzling! We investigate why.

Keywords: skateboarding, longboarding, wheels, mechanics, physics


Longboard Part 3 - Some Chemistry of skateboarding

A skate wheel needs to be lightweight, strong, provide excellent grip yet be flexible and cheap to make - chemistry provides a wonder material - polyurethane!

Keywords: skateboarding, longboarding, wheels, polyurethane, chemistry


Longboard Part 4 - Skate data and analysis

We explain how the skateboard speedometer data can be scaled to calculate your speed in any units you like (mph, km/s, m/s etc). Using a basic spreadsheet program we also show simple integration and differentiation techniques to determine the total distance travelled and the accelerations along the way.

Keywords: skateboarding, longboarding, speed, velocity, acceleration, data analysis, integration, differentiation, spreadsheet

The Carbon Revolution Part 1 - The many forms of carbon

The last 40 years has added Fullerenes (C60), nanotubes and graphene to the pure forms (allotropes) of carbon including diamond and graphite. There have also been two Nobel Prizes awarded for the work. This is the story of the carbon revolution.

Keywords: C60, Nanotubes, Graphene, diamond, graphite, chemistry in space, Nobel Prize

The Carbon Revolution Part 3 - Spectroscopy of the Fullerenes

The C60 football molecule has wonderful symmetry which leads it to have some very unusual and simple spectra. We describe the mass spec, IR, UV and visible and NMR spectra of C60 and C70.

The Carbon Revolution Part 6 - C60 Chemistry

We look at the diverse and interesting chemistry of Buckminsterfullerene including its oxidation state and substitution reactions.

The Carbon Revolution Part 7 - Nanotubes

The basic properties of the three types of nanotubes are explored (arm chair, zig-zag and chiral).

The Carbon Revolution Part 8 - Fullerene C28

The small Fullerenes below C60 were discovered in 1985 but still haven't been made in test-tube quantities. C28 looks to be a most interesting structure. This is an introduction to C28.
