I enjoy a lil bit of chemistry. some people say things like “me and my cat have chemistry” but that’s not the kind of chemistry I am talking about here

I almost went back to school for chemistry (but then the pandemic hit and I got conservative about throwing my whole life away), I suspect chemistry scratches the same itch as thinking about computer programs

its not really chemistry precisely but i am super fascinated by high entropy alloys https://www.youtube.com/watch?v=v1B4VbLX9rA rotor fucked around with this message at 21:12 on Dec 19, 2022 |

like so my understanding is that typically you have alloys that are almost entirely one element (say iron) at like 98% and the alloying materials are like 0.3% one thing (carbon), 1% another thing (vanadium) and 0.7% another (chrome) this is done because starting from the base element is an easy starting point and you tweak it from there. Obviously you have this massive explosion of possible materials when you start to say "ok why dont we test all possible combinations of these 5 elements" and no one has ever really done any rigorous exploration of the area until very recently. So people are finding these wild materials with crazy properties like being both very hard but also very ductile and so on, with metals like Al9xCo15xCr15xNi70−x with x ranging from 0 to 35% Its super interesting to me and i wish i understood more about it. rotor fucked around with this message at 21:19 on Dec 19, 2022 |

We should make a machine that automatically makes and tests every possible combination of every metal in 0.1% increments. Probably a lot of crap but there's bound to be some good ones in there too

if you mix a little niobium in with your aluminum, the niobium gets in between the grains of aluminum and holds them together, making the alloy much stronger

my first project in grad school was to try and figure out electroplating copper. kind of a waste of time, better to just pay the professionals. but i moved my setup from one lab to another and i took a bottle of opened concentrated sulfuric acid across several states in a little rubber pail. not sure if i was “supposed” to do that or not.

i liked chemistry in high school, so in college when i needed a physical science to fulfill requirements, i took intro chem. little did i know that this was a weedout class for premeds. i remember leaving an entire page of the final exam blank. still got a B due to the curve. and that was the end of my chemistry story

it’s kinda messed up those courses exist. i think intro physics courses are the same. i got credit from ap chemistry classes in high school so i didn’t have to submit to the weedout courses it was great.

echinopsis posted:this is extremely sick was it one of those high entropy alloys? i think that’s a hot topic these days. they’re mixtures of like 5 metals in almost equal proportions, and they’re supposed to be mixed up at the crystal level (so it’s not like regions of one metal beside regions of another metal. every lattice point ends up with a different element).
