Graphene Conference 2012

Graphene2012

Graphene 2012 International Conference is to be the largest European Event dedicated to the science of Graphene, and will be held in Brussels (Belgium) from 10th until 13th of April 2012. The event, organised by the quartet of the “Phantoms foundation,” “UCL,” “Institute Catalia de Nanotecnologia,” and “CNRS,” is to include a session on the Graphene Flagship Pilot Action which is working to establish the “Graphene Science and Technology Roadmap.” The roadmap, which will be presented to the European Commission and Member States, will hopefully demonstrate the need for long term funding and the support of the European governments.

Miracle Material.

Graphene is without doubt peculiarly splendid and is quickly establishing itself as the champion of materials; grabbing for itself various records in the world of physical properties.  The accolades seem to accumulate every day, with research into the substance being one of the hottest areas in materials science. But what are the most surprising of its properties. Well…

  1. Strength – Graphene is 200 times stronger than steel and so robust that it would, according to Professor James Hone, take an elephant sitting on a the end of a pencil to break through a sheet of graphene no thicker than a piece of clingfilm. The substance is so strong that it is effectively possible to pick up a whole sheet of the material; which means one can grasp at and hold without breaking a sheet of carbon atoms.
  2. No Band Gap – Graphene has no band gap, the difference between a bound and unbound electron. Without a band gap an electron is able to absorb electrons at all frequencies, making the substance ideal for highly efficient photovoltaic solar cells.
  3. Ballistic Conduction – Similar to superconductivity at room temperatures, ballistic conduction occurs when electrons pass through a material unimpeded. The honeycomb lattice of graphene has the largest “mean free path” of any known material.
  4. The highest current density (a million times that of copper).
  5. The highest intrinsic motility (100 times that of silicon).
  6. Conduction in the limit of no electrons (it can carry electricity more efficiently, faster and with more precision than any other material).
  7. Transparency – Graphene absords just 2-3 percent of the light that falls on it, making it perfect for the production of touchscreens. It is however possible to see the material with the naked eye, meaning that when placed on a sheet of white paper it is possible to see a graphene sheet of carbon atoms.
  8. Stretch and stiffness – Graphene has an elasticity that means it can be stretched by 20 percent of its length, yet is also stiffer than diamond.
  9. Thermal conductivity – another record holder. Graphene is the substance with the highest level of thermal conductivity, again beating that of diamond.
  10. Impermeability – Graphene is the most impermeable material on the planet. It is so impermeable that even single atoms of helium cannot pass through it; a quality that makes it ideal for the production of gas detectors.

The role call of accolades and attributes provide a fantastic confirmation of the material’s versatility. Exploring and discovering the qualities of the material make it one of the most anticipated and expectation riddled substances ever. An investment of time and effort in graphene in an investment in its innumerable possibilities.
