How #chemists turned #bourbon waste into #supercapacitors
Hydrothermal carbonization can directly convert #stillage into hard or #ActivatedCarbon. Cossio & Guzman used activated carbon as #electrodes, creating double-layer #capacitors by putting liquid electrolyte between them. Proof-of-concept devices were able to store as much as 48W/kg. Built a hybrid device, with one activated carbon electrode and one hard carbon electrode, stored as much as 25 times the energy per kg

🗨️ Note: Mark is talking about columbite-tantalite or short: #coltan

Tantalum from coltan is used to manufacture tantalum #capacitors which are used for #mobilephones, #computers, #automotive #electronics, and #cameras

Merry Christmas everyone! 🎄
I can finally check that this old Frako is just fine!

Oddly consistent corrosion: every 16-volt electrolytic in the device, plus one 25-volt. All the others were fine (after about 44 years). Or alternatively, all but one of this brand. There doesn't seem to be corrosion anywhere else, so it's probably not flux residues; but would all these have leaked or is it something to do with the metal itself?

Anyway, this is just tidying visible problems; don't know what's functionally wrong yet.

A very informative video on the improvement of sound quality of (professional) audio equipment with capacitors.

This knowledge can also be used in improving the tone of my Bass Guitar which suffers from a 3-6dB loss of signal on the third string (D string)

I knew of two types of capacitor that had the right to their own symbol, but this 1939 manual has six pages of symbols corresponding to different types.

Just in: the long awaited 1937 sequel to the 1927 bible on capacitor production by Philip R. Coursey that I posted a while ago. Even more details, materials and production methods, but now zooming in on electrolytic capacitors. I didn't realize Coursey was the technical director of Dubilier, the first commercial manufacturer of capacitors, which I believe is still in business 105 years after it was founded.
