Graphene 2008 Capturing Carbon Competition Winner
Graphene
Calvin Davidson, Sussex University
In July 2008, Levente Tapasztó et al1 reported their ability to etch graphene nanoribbons using a scanning tunnelling microscope to produce almost atomically precise structures and predetermined electronic properties. This image shows a tungsten [100]
scanning tunnelling microscope tip approaching a stylised sheet of perfect graphene, undulating with a wavelength of 8 nm, as predicted by Fasolino et al2 in 2007.

Pencils of graphite or Graphite of pencils Pencils of graphite or Graphite of pencils
Irene Suarez Martinez, Institute of Materials Jean Rouxel, Nantes, Francen
Graphite is a black mineral, the most common form of carbon, used in the core of pencils. Graphite is made from layers of carbon atoms, in each layer the atoms are packed in a hexagonal 'honeycomb' array. Curiously, if pack a bundle of pencils they also adopt the same hexagonal packing. The picture shows just such a bundle of pencils with an atomistic model of a graphitic layer superimposed in order to show the link between the macroscopic and nanoscopic worlds.
Fundemental carbon Fundemental carbon
Lewis Bush, University of Warwick
The idea behind this was that as well as being integral to any kind of invention or technology, carbon is usually the medium through which these inventions are first brought to life through the humble pencil, a tool which has arguably contributed more to human knowledge than any other.
The Fullerenes The Fullerenes
Calvin Davidson, Sussex University
The path that was to lead to the discovery of the Fullerenes, including C60, famously began with an investigation into the possibility of clusters forming from interstellar Carbon. This image juxtaposes the "Magic Sequence” Fullerenes (C24, C28, C32, C50, C60 and C70) as predicted theoretically by Kroto1 and observed experimentally by Cox et al2, against a striking image of the Helix Nebular produced by the Hubble space telescope.

2 hairs vs 2 million carbon nanotubes 2 Hairs vs 2 million Carbon Nanotubes
Bernhard Christian Bayer, Christoph Tobias Wirth & Stephan Hofmann, Engineering Department, University of Cambridge
Scanning electron micrograph of two human hairs (upper left) and the word "CARBON" composed of approximately 2 millon carbon nanotubes. The writing was defined by electron-beam lithography and the carbon nanotubes grown by thermal chemical vapour deposition. The area shown is approximately 500 micrometers by 600 micrometers. The inset shows the sideview of carbon nanotubes at higher magnification.
Carbon Nanoforms Carbon Nanoforms
Karl G. Nyman, Nyman Digital Arts, and Simon C. Benjamin, Materials Department, University of Oxford
This image shows the creation of carbon 'peapod' nanotubes, an experiment performed regularly in the Materials Department at Oxford. C60 'buckyballs' are sucked inside the tubes by the van der Waals force. The buckyballs have an additional nitrogen atom in their core -- the quantum 'spin' associated with this atom may offer a means to store information in future technologies. Here we see six nanotubes winding around one another to form a 'nanorope'. This rope will be unraveled in a later experiment so that individual nanotubes can be deposited onto a surface and connected to metal electrodes.
Single carbon atoms in graphene Single carbon atoms in graphene
Valeria Nicolosi, Department of Materials, University of Oxford
Aberration-corrected HRTEM image of a graphene monolayer obtained by exfoliation of graphite in liquid phase (Y. Hernandez, V. Nicolosi et al., Nature Nanotechnology 2008, 3, (9), 563-568). This image is of atomic resolution and clearly illustrates the hexagonal nature of the graphene, showing a hexagon width of 2.5Ĺ and a C-C bond length of 1.44Ĺ HRTEM images taken with the Oxford-JEOL JEM2200MCO FEGTEM/STEM, fitted with two CEOS Cs aberration correctors, operated at 200kV.
Amorphous Carbon : The Microscopists Best Friend Amorphous Carbon : The Microscopists Best Friend
Dr Alexandre Gloter, LPS, Universite Paris Sud, France
Amorphous "holey" Carbon Grid. This fine network of carbon strung together in the void of the microscope column is every microscopists best friend, trapping samples like flies on a spiders web.
Neutron Activated Graphite Neutron Activated Graphite.
Lorraine McDermott, School of Materials, Manchester
Autoradiographic image of neutron activated graphite from the British Experimental Pile Zero (BEPO) nuclear reactor core. The core was operational from 1948-1968 with a final decommissioning date scheduled for 2022. Autoradiography produces a visual distribution pattern of radiation, where the specimen is the source of the radiation. Autoradiography therefore provides information on the distribution of radioactivity within a sample. This information is being used to understand how thermal and leaching treatments may reduce the activity of nuclear graphite waste. The area of this autoradiography image is 6 x 9 mm. Hot (i.e. red) colours indicate higher activity.
The Space Elevator The Space Elevator
Calvin Davidson, Sussex University
The basic idea central to a space elevator, or orbital tower, was first discussed by Konstantin Tsiolkovsky in 1895 and the concept was examined in more detail by Yuri Artsutanov in 1959. However, most observers would credit Sir Arthur C Clarke, who passed away this year, with the idea’s introduction into popular culture in his 1979 novel, “The Fountains of Paradise”. Here, a bundle of carbon nanotubes rises to orbit from the Maldives, the closest equatorial location to his adopted homeland of Sri Lanka as a homage to the great man’s vision.

Dr Alexandre Gloter, LPS, Universite Paris Sud, France
Carbon nanotubes, bundled together with organic coated oxide nanoparticles, attach themselves to the surrounding amorphous carbon grid like tendrils.
Unnoticed Inventor Unnoticed Inventor
Lewis Bush, University of Warwick
This was a similar idea to "Fundamental Carbon", only visually I wanted it to be less obvious, I wanted it to look like the shavings from a engineer or scientists pencil which had just been cast aside, but which were fundementally key to the job they were doing.
Mapping thermal strains of Gilsocarbon nuclear graphite Mapping thermal strains
David James
Mapping of thermal strains within the microstructure of Gilsocarbon nuclear graphite. Digital image correlation has been applied to 3-dimensional high resolution tomography scans obtained at the Swiss Light Source between temperatures of 270K and 150K. Higher thermal strains are associated with local variations in crystal orientation and the effects of local porosity on constraint. These data are being used to verify microstructure-based models for thermal and irradiation induced dimensional change.

Transmission electron microscopy image a binder microstructure in Gilsocarbon nuclear graphite. Quinoline insoluble (QI) particles with a size of ~200 nm, can be observed. Well-graphitized crystallites (G) with different orientations are observed between these QI particles. Finer features with a nanosized structure (N) can also be observed.
