Spalters Inc. #9: STM vs xylindein: STM WINS!

879 days ago by Sodabowski | 10 comments »

Hi guys. So, to sum it up, this is Chlorociboria, a.k.a. “the mean tiny hulk”: Making nice things to the wood it lives into (right) because of this pigment, the xylindein: Which response to light in the visible spectrum looks like this: And whose picture I was (almost certainly) the first to ever take with a Scanning Tunelling Microscope.Say hello to my little friend: Now how cool is that? :)

Spalters Inc. #8: fast-extracted xylindein

924 days ago by Sodabowski | 13 comments »

Hi guys, So in an effort to gear up my lab stuff, I recently bought a cheap peristaltic pump on ebay to help extract xylindein faster. Relying on gravity sure works, but it’s damn slow. So I filled up a funnel with xylindein-stained sawdust, connected the output to the pump, set the other end of the pump above the funnel for a closed-loop circuit of sorts, dropped enough acetone to soak all the sawdust, and fired the pump for a few minutes. Wow, I gotta tell you, this modus operandi ...

Spalters Inc. #7: First (preliminary) determination of decay temperature of Xylindein

1008 days ago by Sodabowski | 12 comments »

So here it is: the first attempt at determining the temperature at which the pigment produced by Chlorociboria vanishes. This is preliminary data (you never stress it enough!), furthermore testing will be needed to assess the exact way it happens within a seriously controlled setup. The pigment is stable up to 90°C, then it quickly starts to degrade. At around 110°C, half the pigment has lost its color. At 125°C, only 25% of the coloring remains. At 155°C, only 10% of the green is s...
