of polymer decoration: this polyethylene
crystal is covered by an epitaxial growth of small cristals
from polyethylene vapour (molecules close to paraffin C18).
The short paraffin molecules are oriented by the polyethylene
'loops' on crystal surface, showing the crystal 'four-quadrant'
structure. I obtained this picture (as well as the cristal
itself!) in april 1990 at the Institut
Sadron, Strasbourg, during a practical course on polymers,
crystals and transmission electron microscopy with the group of
Pr. B. Lotz. It's not related to astronomy at all... but it's
beautiful and very exciting science too !
