The stamp of the Chemistry Nobel Prize

This 100th anniversary stamp set contains some unusual features. Take a close look at the Chemistry stamp. It represents a Carbon 60 molecule and is printed with thermochromic ink.

From your knowledge of words, you know that ‘thermo’ refers to heat/ temperature while ‘chromic’ refers to colour.

This particular stamp looks different depending on whether ‘cold’ or ‘warm’. When it is ‘cold’, you will see a white net on a black pentagon background. To make it ‘warm’, put your finger on the stamp. Heat is transferred from the finger to the stamp, revealing the Carbon particle trapped within the net.

Compare the two pictures to see the difference.

[UPDATE 30 Aug 09: Professor Sir Harold W. Kroto, Professor Robert F. Curl Jr and Professor Richard E. Smalley, were awarded the Nobel Prize for Chemistry in 1996 for their discovery of the C60 particles. The last line of this ReTRIeVIA piece should be:
The Royal Swedish Academy of Sciences has decided to award the 1996 Nobel Prize in Chemistry to

  • Professor Robert F. Curl, Jr., Rice University, Houston, USA,
  • Professor Sir Harold W. Kroto, University of Sussex, Brighton, U.K., and
  • Professor Richard E. Smalley, Rice University, Houston, USA,

for their discovery of fullerenes.]

  2. I am grateful to Professor Kroto for pointing out the inadequacy of the citation in my retrievia item.

    The citation should have been as follows:
    Professor Sir Harold W. Kroto, Professor Robert F. Curl Jr and Professor Richard E. Smalley, were awarded the Nobel Prize for Chemistry in 1996 for their discovery of the C60 particles.

    The last line of this retrievia piece
    The Royal Swedish Academy of Sciences has decided to award the 1996 Nobel Prize in Chemistry to

    Professor Robert F. Curl, Jr., Rice University, Houston, USA,

    Professor Sir Harold W. Kroto, University of Sussex, Brighton, U.K., and

    Professor Richard E. Smalley, Rice University, Houston, USA,

    for their discovery of fullerenes.
