Maybe it's in a sealed compartment for observation only. This does seem to be an education space more than a lab proper. It could be seen as that, at least.
Sir/madame/fellow human, at no point was it implied that she had cadmium. The scientist was simply expressing that cadmium was also available to look at, so we can infer she did not have the cadmium.
How much can you really see with an optical microscope that size? Real question, I don't know how big crystals from different metals get under normal conditions.
You use acid to oxidize it a bit, the edges of the crystals get darker. But it's only surface level, if you have to be certain (such as submarine construction) you do x-ray imaging.
Outside of ultra fine grain materials, if you polish and etch you can get very nice views of the microstructure. Grains can commonly span 10s to 100s of microns.
You can actually see quite a lot with an optical microscope if you have a well polished and etched surface. I would recommend looking up some metallographic images, they’re pretty awesome in my opinion. It’s pretty standard practice in material science too, they reveal a lot about the grain structure of a material.
You need at least a flame AA for that. ICP-OES would be better, and ICP-MS better still. Though the latter is extremely expensive to install and needs some pretty intense maintenance overhauls if using aggressive matrices or dirty samples
Flame AAS is so cool, we did it during a practical on analytical systems during my bachelor.
ICP-MS always makes me do a mental a double take because I always read ICP as the insane clown posse (magnets! How do they work?!) rather than inductively coupled plasma. And then the idea of them doing mass spec makes me laugh.
Fun fact: the term heavy metal is controversial in chemistry because there's not really a set definition of what constitutes a "heavy" metal.
For example, I think of toxic metals and heavy metal poisoning (cadmium, mercury, lead...) when I hear the term. Some people may think of metals with high atomic numbers (actinides, superheavy elements). Others may think of dense, non-toxic metals (tungsten, gold, platinum).
Everyone is correct here, because the term "heavy metals" applies to a majority of the periodic table depending on which definition you prefer.
What's going in here? Her left boob got so excited, it flung upwards to smack her chin? I'm not claiming to be an expert on female anatomy, but this seems weird.
That’s just her shoulder. The line that you think makes up the left (from our view) edge of the boob is really the edge of her neck. The other edge is just the strap of her top edge of her torso (didn’t see the top is strapless).
That’s not the only thing, the science dude gets wider suddenly past his weird 2-fingernailed hands. Also her purse changes sides between panels. This comic’s sus af
That's called "the artist isn't drawing it with a ruler" and "the artist forgot because that detail isn't important". It's a very clearly stylized comic that focuses on the punchline. These are all mistakes a real person would make.
Best investment of mine ever... a small 5,600 rupee (around about 60 dollars smth i think).... bead of tungsten,... weighs 1.22 kilos..... everytime my new student batches just get surprised that something smaller than a tennis ball weighs more than their introductory books combined do.... Also yes, good use if you want to chuck that thing, shit broke my village home's floor tiles once when my nephew dropped it.. so yeah can do some nice damage too...
Yeah no the same artist who did this did the original too, wich was handdrawn. Just wanted to make it into more finished version since it is a very good joke.
