These are images I've taken on my lab's TOPCON ABT-150 SEM, with either
a Tungsten filament or a LaB6 filament. I find the SEM to be
the most interesting techno-toy I've ever used, and I'm happy to get to
use it almost every week at lab. |

I have an element collection. It's nearly complete, and here
I have a navigable periodic table where you can see pictures of my
elemental samples and read some interesting tidbits about them.
These tidbits include elemental characteristics, how the
samples were obtained, stories related to those elements, etc. |

These are a couple videos of how to clean silver without any scrubbing or
loss of metal. You make a big pot of boiling water, add baking soda and
aluminum foil, and touch the object to the foil. This sets up a battery,
reducing the silver tarnish (made of silver sulfide) back to silver metal.
You'll know you got it right if you see the silver get shiny, and if the
pot starts to smell like rotten eggs, from all the sulfur.

My results of growing crystals, mostly of water-soluble compounds using
the evaporation method. In this method, one prepares a saturated
solution of something by dissolving a whole lot of it until no more
will dissolve. One then puts in a 'seed crystal' (from a previous
growth), and transfer the solution & seed crystal ONLY to a new
container every day for a week or two.
This page also contains crystals of highly pure Bismuth grown by supercooling a pool of molten metal. |

Interesting exothermic reactions to which I have bared witness; perhaps
even partaken in! |

This poster is currently illuminated by RGB LED lights in my living
room. I do intend on printing an RGB version (instead of CMYK
from most printers), so it will respond better to the RGB LED light. |

While polishing some samples at lab, I observed droplets of water
remaining in place far longer than I have expected. I have
yet to explain how a droplet of water can hold its shape for up to ten
seconds on a rotating disc wetted with water. If you have an
explanation, please let me know - I would be most interested to hear it! |

One foreign exchange student (affectinoately deemed "The Kaiser" by our
lab staff) used to work on his BMW in our lab's parking lot, spilling
car liquids everywhere. On one rainy day, he spilled a little
engine oil, and it formed thin films that scattered rainbow bands of
light all over the parking lot. This is the best I could
capture them on a cloudy, rainy day. |

Our lab bought a fancy LaB6 filament for our SEM. Turns out it
was defective - the company claimed it was an error in heat treatment
or something. Looks to me like they forgot to grind the faces on
it. Either way, check out how Lanthanum Hexaboride grows in
perfectly rectangular sheets out of a single crystal. |
