I think the idea behind it is really clever. You don't know how to manufacture the material. Create a test that separates the good particles. Sieve through mountain of crushed material, out comes small amount of good stuff. Genius.
- wolfi1 2y agoI would call it the "Cinderella Method" after the German version of it:https://en.wikipedia.org/wiki/Cinderella#Aschenputtel,_by_the_Brothers_Grimm https://en.wikipedia.org/wiki/Cinderella#Aschenputtel,_by_th... ("Die Guten ins Töpfchen, die Schlechten ins Kröpfchen"_)
- ljsprague 2y agoWhy do the good ones go in the potty and the bad ones in the crib? (Google Translate.)
- aidenn0 2y agoGood goes in the pot, bad goes in the crop. (i.e. keep the good, toss the bad)
- tinco 2y agoPotty would be a small pot, for keeping the lentils. Crib is a mistranslation, I don't know German well enough to know if it's even a possible translation but the word means small crop. The ashes go into the crop because they are fertilizer. Both words, pot and crop, are in diminutive form which makes the sentence have a sing-song feel and memorable.
- card_zero 2y agoCrop as in "bird's throat", I think. Good goes in the kitchen, bad goes in the pigeon.
- ChuckMcM 2y agoAgreed very cool. I had seen a previous process where sorting out conductive nanotubes from non-conductive ones by inducing a current in them and pull them into a different sluice with a magnetic field. Interesting stuff.
- tired_and_awake 2y agoYeah this is almost common at this point, specifically with carbon nano structures. The reason why is it is very expensive to manufacture specific structures but cheap and easy to make a ton of random structures. So yeah you "just" sort through the random ones, of course sorting through to find the desired structure can be fantastically difficult, but hey it works!
- colechristensen 2y agoHalf of chemistry/chemical engineering seems to be just various techniques of separation of the things you want from the thing you don’t want. Strong magnets might be unusual, but chemistry is full of doing strange things to get results. I just watched the explosions and fire guy set fire to a mixture of things to synthesize something. If i remember correctly it was a glowing nanoparticle.
