OPT407:
Electron Microscopy
Spring 2010
Final Project
To us who resides at
Rochester
area, we have to prepare for the cruel winter weather-snowing.
Observing with naked eye, snowflakes are not exactly as numerous
children books described as having hexagonal symmetry. According to
articles, the shape of the snowflake is determined broadly by the
temperature and humidity at which it is form. So near
–perfect snowflakes may be more common in pictures because
most snow particles are irregular shaped. In addition, the size of the
snowflake particles may be in the level of micros, so that the usual
light micro scope may be inadequate in observing such sample with high
resolution. It would be really interesting to see what snowflakes
actually like and maybe investigate the composition of it in the SEM or
possibly TEM.
