Nanoscientists at the University of Nottingham’s Nanotechnology and Nanoscience Centre were able to etch the entire periodic table onto a single human hair using focused ion beams. The result was the complete table, including all known actinides and lanthanides, that was so small that it could have been written on post-it note well over a million times with room to spare. Check out the process after the break, where you can also watch them engrave “Merry Christmas” on a snowflake.
