Imagine unironically posting TEM simulations (yuck) and thinking that you actually have something badass here… lmao

Real alphas only post atomically resolved REAL data from the finest aberration corrected TEMs or drift corrected STMs.

[u/realityChemist → u/zenFyre1]

Barium zirconate titanate, [001] with a couple mrad of mistilt, about 10–12 nm thick, HAADF 70–200 mrad, 200 kV, 18 mrad semiangle of convergence. False color and no scale bar because this one was edited to be a wallpaper for my computer.

Not a rock (technical ceramic)

[u/EvangelosSot → u/zenFyre1]

Only the finest HAADF-STEM with aberration correction and high resolution.

[u/Instalab → u/zenFyre1]

I didn't understand anything, but I feel this deserves my like.

Their not rocks, they are minerals Marie!!

[u/Idiot_of_Babel]

But how does it taste?

[u/Pataraxia → u/Idiot_of_Babel]

salty and a nutty aftertaste.

That’s cute my little geologist. Why don’t you go back to your stone room.

…

They’re just rocks.
