No, I don't, and can't find any writing about this at all, do you have any links? Because that sounds amazing
- Zanni 4y agoHere's the text of a patent describing the process. [0] Googling "fullerene" will get you more useful hits than C-60, so, e.g. "generating fullerene from arc welding." [0] https://patents.google.com/patent/US5227038A/en https://patents.google.com/patent/US5227038A/en
- CRConrad 4y agoBing found two URLs... Both to this page. Google found one -- also here -- and two ads. This: generate fullerene "arc weld" Worked a bit better in both. N.B: Quote marks only around the "arc weld" bit.
- gorgoiler 4y agoI believe the original paper on Buckminsterfullerine aka Bucky balls aka C60 described the approach. Basically do violent stuff with carbon and stick it in a mass spectrometer. The violent carbon bit is arc welding, because the arc welding tips are made of graphite.
- eesmith 4y agoWikipedia informs me that the first papers used a laser (https://www.nature.com/articles/318162a0 https://www.nature.com/articles/318162a0 - "graphite has been vaporized by laser irradiation, producing a remarkably stable cluster consisting of 60 carbon atoms") (1985) and the arc welding approach was a few year later. The paper "Solid C60: a new form of carbon" (1990) paper describes using benzene to dissolve the soot to extract the C60 (https://heyokatc.com/pdfs/MISC/Solid_C60-_a_new_form_of_carbon-_kraetschmer-huffman-n-1990.pdf https://heyokatc.com/pdfs/MISC/Solid_C60-_a_new_form_of_carb...).
