World's Smallest Periodic Table

A Chemistry Professor at the University of Nottingham in U.K. received a super cool (in the most geeky way) present for his birthday -- the Periodic Table etched on a strand of his own hair. This was done for Professor Martyn Poliakoff by the nanotechnlogists of the university. This is what it looks like:

The 118 elements of the Periodic were carved using a beam of gallium ions. This technique is usually utilised to do repair works on extremely small components of semi-conductors. So, how small is this Periodic Table? Each letter carved has a height of four microns -- that is 4 × 10^-6 m. The entire Periodic Table is 88 microns wide, and 46 microns tall. If this were to be done on a Post-it note, almost one million of them can be fitted on a single piece of the note paper. 


A video was made to show how the process was carried out. Check it out here:
