Unknown funding in my research
I want to ask if someone knows how funding in chemistry/astrophysics works. I've a paper that is receiving many fundings that the application where is uploaded (zenodo.org) forces me to introduce and by now I don't know why.
I've had many legal problems in my work and this is the straw that breaks the camel's back.
What do you think?

Everyday uses for organic chemistry?
So I find the subject pretty fascinating, but I have limited knowledge so far. Has anyone found that it helps them do stuff hands on in daily life (rather than in an industrial context/using the products of industry)? For example using some nifty org chem trick to spice up a dish you are cooking.

I'm afraid of writing your career wrong.
Hi, I was thinking of writing a book where the main character studies Chemistry. The problem is that I have no idea about the career and I don't want to end up ruining it by writing something badly. So, could you explain to me what your degree is like, some experiences, or advice on things I should definitely or shouldn't write about in the book?

Want to be akin to a Cosmetic Chenist
Hi, I am 50 years old and want to start my own skincare line. I’m not going back to school for chemistry or anything but i’m interested in learning what courses people might suggest to learn how to make formulas. I saw another post on here about a cosmetic chemist which is why I’m posting here. Your help would be greatly appreciated. Thank you!

Interference of 304 Stainless Steel in Chemical Reaction
Would 304 Stainless Steel interfere in the following (rough) procedure for growing Topaz? Do I need a PTFE liner? Any suggestions for possible liners other than PTFE? As I’m having trouble finding a liner for my specific chamber.
Materials
- Aluminum nitrate Al(NO₃)₃ or aluminum hydroxide
- Silicic acid or fine SiO₂ powder (quartz flour)
- Ammonium fluoride (NH₄F) – source of fluorine
- pH buffer – e.g., HNO₃ or HCl to slightly acidify
Procedure:
1. Prepare the Hydrothermal Solution:
• Dissolve:
• ~1 g Al(NO₃)₃
• ~0.5 g SiO₂ powder
• ~0.3–0.5 g NH₄F in 20 mL DI water
• Add 1–2 drops of dilute nitric acid to slightly acidify (pH 4–5 range).
2. Seal & Heat:
• Load solution into the reactor (fill to 60–70%).
• Seal autoclave and heat to 210–220°C over 3–4 hours.
• Maintain for 7–14 days.
4. Cool Down & Rinse:
• Let cool to room temperature.
• Wash resulting crystals with distilled water.
• Dry in desiccator or open air.

question regarding chemically grown crystals
hello there.i've made alum crystals and am starting to grow copper crystals (both the blue one from straight copper sulfate pentohydrates and the ones from that same stuff using a power supply to make it into regular copper crystals) and i was wondering if it would be feasable to form those crystals inside a mold,instead of letting them grow freely.i mean,doing like a mold of a specific shape between the anode and cathode,with the mold being like a tube with its wall shaped into something like a cube or whatever.if someone has tried before,i'd happily ask for any information you may have!

Chemical that dissolve lead and preserve steel
Hi, I am reaching you because I am seeking for a chemical solution that would dissolve lead but keep steel (and the blueing coating) and chromium preserved (if there is any)
To be more accurate : I have a piece of chromed steel that has lead stuck to it and I don't wanna wear the chrome by mechanically remove it, so I am seeking to dissolve lead by soaking it into a chemical that would only attack lead.
I thought about low concentration nitric acid, but it attacks chromium. Is vinegar working good? I've read that it can be combined with hydrogen peroxyde. But will it preserve steel?
Thanks

Chemistry Degree: Physics vs. Biochem Minor
I am currently a rising sophomore majoring in chemistry on the ACS-certified track (BA) and am currently considering potential minors. My main options right now are physics and biochem/molecular biology (the program is the same at my university). I'm not 100% sure what area of chemistry I want to work in in the future, but I know I want to work in research/industry. This summer I have been working in an inorganic/materials lab doing crystallography stuff and I think it is interesting, but I feel a little out of my depth since I haven't taken any of the higher level chemistry classes yet. I'm not the biggest bio fan, but I do find pharmaceuticals and biochem interesting, though I don't want to work in biotech.
I have already taken the first two introductory physics classes required for the chemistry major and physics minor. To complete the physics minor, I would have to take oscillations waves and optics in the fall and quantum physics and relativity in the spring. I was planning on taking Bio 101/102 this year to prepare me for biochem/refresh my bio knowledge and so I can take bio electives later on like marine biology and ecology. If I were to take these physics classes this year, they would replace bio, and I would either not take bio or take it my junior year.
The main reason I am considering a physics minor is because I want to take thermodynamics. The two physics courses I listed above are pre reqs for thermo, and by the time I completed thermo I would have finished the physics minor, so it seems a logical path to take. However, biochem seems better suited to pharmaceuticals and I'm not sure that I want to work in materials chemistry in the future.
The biochem minor only requires the two biochem courses I have to take for my major anyway as well as two additional electives, so it would be easier to complete.
I suppose I am mostly asking for insight on what sorts of opportunities a physics minor would open up for me as opposed to just a chemistry degree or a biochem minor. With a physics minor, would it be more challenging to work in biochem fields?
Bio will most definitely be an easier class than optics, but I do take interest in physics and the draw of taking thermodynamics is a hard driver for me lol. Any insight is helpful and appreciated.
TL;DR: I want to take thermodynamics but the prereqs would make a physics minor complete by that point. I have more interest in biochem as of now for my future career, so should I sacrifice bio for physics in hopes of being more well-rounded, or skip the physics minor/push it to my junior year? Thanks!

How screwed am I?
I hope this is allowed in this sub, if it isn't, please direct me elsewhere. I am approaching my senior year as a USA based chemistry B.S. student and I am looking at my future for grad school or starting to work. I have two and a half years of research experience, two internships, and have worked as a TA, so I feel like I am pretty ahead of the game. My topic of interest is radio/nuclear chemistry and with the massive amounts of funding cuts it has me feeling like I did this all for nothing. Thousands of chemists will be laid off in the coming years so do I have a chance of getting hired? Do y'all have any advice?

Anyone (especially patent law related) that companies pay their law school??
hi i'm planning to prepare for the law school but the financial part is the one that i'm hesitating.
I wonder if anyone has their law school tuition paid by their company. I'm currently pursuing a BA in Chemistry (my school doesn't offer a BS), and I'm considering pursuing a PhD before looking for a patent-related firm that might pay for law school tuition, as I've heard some patent companies do that.
I'm wondering:
1. what's your degree: engineering bachelor/master/phd, or whatever major
2. was there any restriction when they pay you?? like you have to go to the law school tuition less then X dollars, etc.
Thank you in advance!!

Can a 16 year old legally buy a compressed nitrogen gas tank?
Hi
So im 16 and I have a summer school project about controlled gas reactions and pressure systems (it is chemistry + engineering). For part of the demo, I need a small compressed nitrogen gas tank, it doesnt have to be big but one of those tanks used for homebrewing or tires
I do have homebrew shops nearby and welding stores nearby as well but i dont know if they would sell someone to my age
I did read one of these store's terms and conditions and it didn't mention anything about age. i also read mixed things online, some say you have to be 18. other people say it depends on your situation and the store (like if it is a small store and individual use, its fine)
I have my own money but I don't want to waste time placing an order online to just get IDed at pickup and get rejected
Anyone got experience with this? do I need an adult? Cause I only have a dad and he often makes me get things for him solo, and he works a lot. I am tempted to contact one of these stores but just posting this ahead of time for now before I make a decision
Thanks
