Re: Graphene made with kitchen blender
#3I'm having a hard time understanding why someone shouldn't make this at home.
This sounds like the perfect experiment I could run with the kids to get them excited about material science. It doesn't need to be a perfect layer of graphene, even a sludge would be good to show them, get them brainstorming about how they would separate out the sludge.
Is there a real reason other than difficulty, why someone shouldn't try this at home?

Probably just the standard mindless disclaimer that people put in front of anything remotely interesting. If you don't want to get your blender dirty, the tape method would be good.
Re: Graphene made with kitchen blender
#5The article didn't mention the sticky tape method of making graphene, but they did put a link to an article about that [1].
Sticky tape (or Scotch tape) can also be used to make X-rays [2]. Now the only question is how to use a blender to make X-rays…

Aren't most nano-particles suspected of causing cancer? I assume this method would generate fairly small pieces that might make people worry about that.
Also the blender mix would probably (1) make lots of foam and overflow the blender, and (2) stain everything it touches.

May I recommend building a centrifuge? When I was in middle school, Scientific American had a cool article about extracting DNA In the kitchen. It was an abysmal failure, but attempting to build a centrifuge to separate the samples was immensely fun. Coolest, most thrilling project I tried in school (messy, too).
Note: blender wiring can catch fire if they are loaded for extended periods of time (don't underestimate the inertia), but old blenders work fine for at least a few minutes. Lego Technic works great, but only with really solid cross bracing. I recommend building a barricade around it (World Book volumes work nicely).
Edit: I should note that it did work. The rig spun two 10mL test tubes on swing arms at the low(est?) speed setting (which is pretty fast at a 4 inch radius). It seemed to work, but I never did figure out if the scum on top was DNA.

Heath reasons I'm guessing.

There have been some low-tech centrifuge designs based on salad spinners - I would think you could make an insert to fit into one that could hold test tubes without too much trouble, though I don't know if it would be powerful enough to separate the graphene well. A good experiment...
