More likely yourself. We had a guy who wanted to use a file to make some BeO spacers fit into a smaller space.
Didn't you keep a small puddle of mercury in a cigar box as a kid?

We used it at the place where I used to work, sometimes there is just nothing better. We even used beryllium tools too...nothing like having your steel screwdriver fly out of your hand into a $10k magnetron...
Most here need to read up. Try 'Googling' "GRAPHENE" Diamonds are second rate, compared to graphene.

- Ligament conductivities greater than 1700 W/mK
- Bulk apparent thermal conductivities up to 175 W/mK
- Very high specific surface areas (>20,000 m2/m3
- Low coefficient of thermal expansion
- Excellent acoustical adsorption
- Excellent electromagnetic shielding

Probably true, but as before mentioned, carbon / graphite is at hand, graphene is not, and won't be for any foreseeable future 😀

Coward! We were just speculating anyway. Please, just use aluminum. It is the only metal that has not increased in price big time, recently. Such a deal!

Ahem, not really, and it's gonna go through the roof just like copper within a maximum of 2 years, it's already on it's way

Old carbon mics worked just on physical contact. Battery electrodes too, for that matter. Not to mention all the other elements that carbon reacts with. Getting electrons in and out won't be a problem. The problem will be getting currents that we would call normal in audio, although I imagine that will prove simply to be a case of paralleling the active portions of the circuit.
Note that they've already built FETs with graphene.

On another topic, there are at least 2 separate papers to be given at the AES in Amsterdam this spring. How about that? One is about cap nonlinearity (I gave my first paper on this at an IEEE conference, 30 years ago) and the other is about mechanical resonance (what a concept!).

Are you coming to Amsterdam, John?
I also noted papers by Doug Self on analog amplifiers and Bruno Putzeys on digital ones. Should be a nice comparison!
