List #12--10 Interesting Branches of Chemistry

Something that many deductionists find interesting is science.  After all, science involves a lot of logical reasoning and investigation.  I am doing a list series on sub-branches of different scientific disciplines, and I'm starting with chemistry because I just really like chemistry.  Here are some interesting branches of chemistry:

1. Analytical chemistry--The chemistry of what things are made of, which includes a lot of testing and fancy equipment to take things apart.  I imagine it's very hands-on.
2. Astrochemistry--The study of quantities of different substances in the universe.
3. Agrochemistry--The study of chemistry as it pertains to agriculture, like growing food and protecting the environment.
4. Biochemistry--The chemistry of living things, such as chemical reactions inside organisms.
5. Chemical engineering--Using chemistry to solve problems.
6. Geochemistry--The chemistry of the earth.
7. Nanochemistry--Chemistry on an incredibly small level.
8. Radiochemistry--The chemistry of radioactive things.  Also used in relation with non-radioactive things.
9. Stereochemistry--This is the study of how atoms are arranged in molecules.  The Wikipedia article didn't go into too much depth, probably because this is a fairly mystifying topic, even for someone like me.
10. Thermochemistry--The study of the effects of heat on reactions.

I hope this is a good start to my series.  If you're interested in any more, look at About.com's chemistry branch list where I found a lot of these.
