this pringle has a hexagonal grid of dimples on either side… in transmission they create a moire pattern

The commercial term 𝑛𝑎𝑛𝑜𝑚𝑒𝑡𝑒𝑟 refers to a new, improved generation of silicon semiconductor chips

this parenthetical will put some through the five stages of grief
ALT screenshot of a paragraph of serif text that says “The IEEE member is in charge of R&D for new chips built using TSMC’s 3-nanometer process node, expected to go into production later this year. (The commercial term nanometer refers to a new, improved generation of silicon semiconductor chips.)”

these are the things that just randomly appear in the lab from time to time, and it’s probably best not to ask

always remember to lightly oil the inside of your vacuum lines, it helps the gases flow more smoothly

this vendor promotional pen has a built in caliper, but the vernier has the same spacing as the main scale and so doesn’t do anything

a big reason why they had huge screens in cars before other auto makers is because no automotive grade screens that large existed, so they just put laptop screens in there. then (big surprise) they all failed after a few years

oh, you used [commercial package] to acquire your data??? tsk tsk tsk… why didn’t you use [messy, hacked together, open source tool that came to me in a dream 2 years ago, that i haven’t written yet] instead?

how it started / how it's going
Take a look at a sketch by physics laureate Ernst Ruska, dated 9 March 1931, of the cathode ray tube for testing one-stage and two-stage electron-optical imaging by means of two magnetic electron lenses (electron microscope). Ruska was awarded the 1986 physics prize for his work.

in case you were wondering: a wet dry vac will suck up liquid nitrogen but it will *not* sound good doing it

metallurgists will show a TEM image like this and then say some absolutely made up shit like "dislocation motion," "anti-phase boundaries," "burgers vector"

look guys, i don’t know how to break this to you all, but… well we opened up the objective area on one of the scopes today and it turns out the beam is red when it hits the sample 🤷

[debugging electron microscope problems] have you tried flipping all the electrons to have positive charge and flipping them back again?

capacitors are like little hotels for electrons. rest stops on the information super highway.
unfortunately these capacitors are like a motel 6 on the jersey turnpike—overflowing with toxic sludge

i used to think i could control electrons with my mind but it turns out electrons & i just have very similar ideas about what stuff electrons should do

the reason you often see liquid nitrogen dewars in electron microscope rooms is because the presence of “tube with not enough air in it” needs to be offset by “tube with too much air in it” in order for the room’s humours to be kept in balance

they did it. they made perovskites horny
Crystals are picky, but they can find their match too!

a modern transmission electron microscope is mostly just a big computer, but with the critical distinction that about 0.00000001% of the electrons take a ~2 meter long detour through empty space

the year is 2089. Gatan releases the K42 detector. In superresolution mode it captures 10^80 pixels. In one frame it measures the universal wave function. It stores it as a 31.5 bit integer. While generating the preview image it collapses into a black hole and the universe ends

btw this is the thing that makes high resolution images
btw, this is the thing that makes lab meat
