What does /chem/ study other than chemistry? Do you read about disciplines other than your own? We are one of the most applicable sciences, and it's sad to see people rot away in their labs

>>7690248
It would be nice to see hybrid chemists. Working in both environmental issues and the renewable energy sector.

>sad to see people rot away in their labs

debatable. Sometimes we need this.

>>7690248
I'm going to study nanotechnology in hopes of making more efficient solar panels.

Also I'm an apprentice gunsmith

Could nuclear chemist go into Nuclear engineering graduate or would the physics kill me

chem freshman at ucla here

please kill me

i wish i had applied to berkeley

I'm working on a bachelor's of science with emphasis on chemistry / microbiology. Looking to get a job as a Medical Technologist and or work under professors as a research student while I study.

I want to find new uses for microbes:

>https://en.wikipedia.org/wiki/Algae_fuel

Also mapping the body's micro flora is the next frontier. Every inch of the small intestine is full of different bacteria 100% essential to your life. Cutting out one section of your small intestine could hack out the bacterial colony for calcium bio-readying and your bones would become brittle within days.

Basically I feel we're just at the tip of the iceberg for microbiology topics and realizing how much more work there is to do. There's great implications of studying the evolution of a certain bacteria and mapping that with anthropological data for history reasons. It just goes on and on.

Data is always related.

To be a Medical Technologist if you want to work in a hospital/medical setting you'll most likely also need an associates in medical technology or at the very least some kind of certificate as a MT. Most medical technologist job postings request that you have an associates' degree specifically in medical technology, not microbiology/chemistry.

Getting my B.S. in Food Science and Technology/ Chem minor this academic year. Looking to apply to UC Davis or University of Wisconsin- Madison for my Master's in Food Chemistry

Can I get anything out of nuclear chemistry?

http://www.pdf->archive.com/2015/06/13/clayden-organic-chemistry-2nd-edition-c2012-txtbk/

A first and second year undergraduate organic chemistry textbook, specifically geared to British and European courses and courses offered in better schools in North America. The emphasis is on clarity and understanding, with very careful explanations of difficult concepts, many examples related to everyday life, and a fresh and student-friendly writing style.

alternatively, kahn academy.

Any tips for someone considering extracting dextromethorphan from brompheniramine maleate. For "research purposes"

Speaking of drugs, I was thinking about it the other day; could the blue in WW's meth be prussian blue? I was thinking of a way to make methylamine in an industrial capacity, and hydrogenating cyanide would be a clean and green (if not a little mean) way of making the stuff. Think about a little iron from the reactor picking up leftover cyanide, or a byproduct of some strong oxidation making some FeCN

>>7691374
Thats an interesting hypothesis. I always just assumed it was a heavily conjugated cross-coupling byproduct lol, Although admittedly I haven't really thought about it much.

A complexed impurity makes a lot more sense

All I could find online was this
>The trademark blue color of Walt’s meth, by the by, is actually a little odd. High-purity meth is clear in color. A blue tint suggests an impurity, but there’s no impurities in the P2P process Walter is using that should color his final product blue. Is Walter deliberately adding a dash of something else? The show doesn’t say.
> Walter: “And if our reduction is not stereospecific, then how can our product be enantiomerically pure?” (In other words: if our reduction generates both enantiomers, how does our product contain only one?)

https://puffthemutantdragon.wordpress.com/2012/08/12/science-on-crack-2-walter-white-cooking-crystal-meth/

The blue meth is enantiomerically enriched, hence there must be some measure of enantioselective catalytic activity occuring in the reaction.

Food for thought huh

>>7691437
>High-purity meth is clear in color
And many dyes are visible in the ppm (read: 0.0001%) range. IIRC their purity ended at one decimal.
What are some other possible chromophores though? I once esterified a carboxylic acid attached to an oxazolidinone and ended up with a bright blue, somewhat polar byproduct

Orbitals aren't even that difficult, literally just get number of protons, and divide 360 by n.

I'm a 3rd year chemistry undergrad.
I have an associate's degree in applied science now, and I'm not sure if I should keep with this.
I haven't been able to learn shit from lectures pretty much since I got here; everything I learn is from the textbook or secondary sources.
I've had to take classes that are heavily influenced by feminists because the university wants me to be "well rounded".
They're literally trying to teach me about the patriarchy and wage gap.
That means I'm paying $6k a semester essentially just to use the college's lab, and I only get to run the experiments they want me to, all the while they make me drudge through shit to have the privilege.
The money I'm using to get through college is my own.
I could spend the money I have on making my own lab and then independently study everything I want to know.

Will using my own lab become too expensive eventually?
Will I ever be able to join a research team if I learn independently?
If I DO get a bachelor's degree in chemistry, what would reasonably be the next step?

My love of chemistry has gotten me this far, but I don't like where I'm headed, and I don't know where I would want to go once I got there.

What book should I get to learn thermodynamics and kinetics?

Doing chem/neuro, hybrid science + hybrid science = jack of all trades, master of none. I don't know what I'm doing with my life. I want to someday own a start up but I have a feeling I'll end up being a highschool science teacher

>>7691881
Get the degree, join a good team(usually made of people who don't like parties), get rewarded. This is the best advice.

>>7690248
A lot of mathematics mostly.

>>7691437
I always just assumed it was the damn lazy-ass writers making a mistake.
Probably the same guy who proposed the thorium nitrate tube furnace straight off erowid and the fuckers who didn't laugh him out of the room tbqqiah

This is where I am too. I'm autistic enough that I just can't force myself to suppress my well-supported dissenting opinions / pointing out obvious fabrications/inconsistencies/fallacies and maintain the utterly thoughtless echo chamber the prof wants (idk, it feels like denying the self or disrespect or something, hard to pin down, but a definite compulsion) and so I miss the dual necessary-sufficient condition for an A in any of those.
It's ironic because this seems awfully like what they would call "ableism"
Bonus: we had a mandatory orientation module that "taught us not to rape" and used unironic trigger warnings
And jesus fucking christ, "well-rounded" is the biggest crock of the year. As if I didn't read widely regardless and as if the dreck they required us to take could in any way compare to the profound philosophical/literary exploration I have done and can only do independently and as if the complacent throngs who have to be forced to explore further than ten inches in front of them actually benefit from this

>>7691881
>I only get to run the experiments they want me to
If you can justify it, you can run it. Don't take no for an answer unless there's a damn good reason, and if you get resistance, keep quiet until you get results.
>$6k a semester
That's fucking nothing, compared to the costs of owning and operating a lab. Stick with it, get good grades, and apply to a grad school that isn't shit.

I got a sample consisting of water, proteins and very fine sand. I need to determine the sand content. Is it possible to remove the ash created by combusting the sample somehow?
I'm thinking dissolving the ash in sulfuric acid. Any other ideas?

Hey guys, I would absolutely love it if someone could help me with Molecular Spectroscopy.
If you have a molecule with several different atoms, is the emission spectrum from that just the spectra from each of the constituent elements, plus a few peaks in between because of rotational/vibrational energies?

It's surprising how little I can find about this on tinternet.

>>7694088
It totally depends on what sort of spectroscopy you're doing.
UV-vis: different energy levels of the electronic orbitals.
IR: Different vibrational modes of the atoms (bonds bending, stretching, etc)
Raman: Like IR, but using lasers. Shows different modes.
Microwave: different rotational modes, I think? Not sure, never done them.

Then:
EPR: electronic structure of paramagetic species, by seeing how unpaired electrons behave.
NMR (what I do, god-tier, fuck everything else NMR is your friend): radio-frequency transitions of the nuclear spin. This tells you a *lot* about the electronic structure, electric fields, bond orientations etc.

Gas-phase elemental emission spectra don't really have a place in any interesting chemistry that I'm aware of. They exist, cool, now lets move on to more interesting structures.

It's visible range between 400 and ~700nm. Would it be fair to say that since pic related has a sharp peak at ~656 that it probably has Hydrogen in it?
Also I don't know nearly enough about this to know the difference between EPR and NMR, sorry. it's just a gas discharge tube shining onto a diffraction gating

Just finished my degree. Considering doing honours specialising in med chem or NP chem. There are a couple of pretty interesting projects going on at my university.
Any advice for a prospective student
