Recommending an amazing book "Evil Chemistry"
Its called "Evil Chemistry" by the Swedish author Ulf Ellervik, professor in organic chemistry. It has won the Swedish Pi-prize of 314,159 swedish crowns and is truly a masterpiece. Its main focus is the dark side like drugs, poison, explosives, death which is fun and interesting but how much there is to learn about chemistry in our everyday lives from these "evil" topics. Its a cool and profound perspective with interesting history related to it. A book I can warmly recommend for anyone even without previous chemistry knowledge.

Computational to Experimental
I’m expecting to graduate with my PhD in computational chemistry in May 2026. I don’t do much programming or theory, just python scripts to generate input files and my research is related to atmospheric chemistry. PI is a very well known name.
I’m thinking of jobs and it seems impossible to get an industry comp. chem job. I was thinking about joining the US Air Force as a chemist via OTS, but before I talk to a recruiter, would this hurt my resume? The way I see it is I would have computational experience from my PhD and then wet lab skills from the Air Force but not at a PhD level. Would this be looked down upon in industry since I’m not PhD educated in experiment? Or would it help since I’d have work experience in both computation and experiment? Has anyone else done a PhD in computational chemistry and ended up working in a lab?

Chemical company with tons of capacity but nothing to make
\~2 years ago I joined a family business in the chemical industry. Company is \~50 years old, had 6 employees, completely absentee ownership, and was run by a general manager who toed the line between negligent and careless. Plant was literally full of garbage, poor safety culture, was overall not a great place to work.
I'm 3rd generation in the family business. 1st and 2nd generations have several other much larger and more important business interests to attend to and this company doesn't make it on their radar. 1st generation is still working but dealing with health issues (late 80's), 2nd generation has spent their career cleaning up after 1st gen and is ready to retire, I'm the oldest member of the 3rd generation and none of my siblings or cousins are stupid enough to jump into this mess.
I have an engineering background and previously worked in tech but not chemical engineering. When I joined I spent a year cleaning, improving safety + plant conditions, investing in equipment that was sorely outdated, etc. To give you a feel for how much of time capsule this place was: We were finally able to process orders without a typewriter as of January 2024.
We've streamlined so much of the process that we could easily 5x our output and not spend a cent on new equipment. Most of our equipment is sitting idle 80% of the time and we just have 1 shift. Honestly I don't even care about selling something profitably, I'm just bored. We have a couple of 3rd party salespeople + distributors selling our various products, but most of it is stable formulations that were spec'd in years ago and haven't changed.
My question is this: if you had free reign of a place like this, what would you make?
We have a 250-gallon and a 1000-gallon steam jacketed kettles, a 1000-gallon pressurized reactor, and ambient mixing kettles ranging from 5 gallons to 5,000 gallons per batch. We have holding tanks to load/unload tankers, a basic 200-gallon mixing for explosion-proof solvent mixing, and a 2,000 lb capacity ribbon blender. If you were to define a commodity chemical, a market, or a type of chemical reaction, what would you want to do?

hi! I am entering my second year of undergrad as a chem student here soon :) I love chemistry, but i can’t help but feel a little discouraged seeing how educated and knowledgeable you guys all are! I would love to hear about what got you into chemistry and your experience in the field. Hoping i start to feel like i know something about chemistry after the next couple years of studying it, because right now i feel a bit behind! Thanks!

Analytical chemistry books that don't depend of expensive machines
Maybe I'm dreaming too much, but are there analytical chemistry books out there from which you can learn techniques that don't depend on expensive machinery (e.g. NMR, MS, ...) (IR, UV or a melting point apparatus is ok). Maybe older books that were published before NMR and MS is what I'm looking for, but maybe there's something out there more relevant to today's problems. If possible I'm looking for something that can be used in ochem and biochem. I don't mind if these techniques take far longer to carry out (e.g. fractionation of the compound into molecules for which you have assays you can compare with).

Raman System Results Inquiry
Hello all--
I am part of student group building a Raman Spectrometer system to differentiate between fabric types. As optics students, the interpretation of the results is not our particular forte.
We have noted the same general shape for all of our fabric samples. While some of the samples do contain the expected characteristic Raman peaks, we are not completely sure what this ambiguous hump could be.

We tested another Raman active sample, ethyl alcohol, and received a discernible expected peak after multiple tests, so we don’t fully believe this hump is the result of a malfunctioning optical system.

But now as this is too late and now I am very serious about my studies and want some like this too.
Anyone who is damn serious so DM and let’s get started very soon.

When E.J. Corey (Nobel laureate) at Harvard University lost two students to suicide, it made international news.
UC Davis’ chemistry department has lost a total of five people to suicide. Four of these suicides took place within a one-year period around 2016-2017 while I myself was suicidal.
Xu Cheng from Dave Goodin’s group.
Philip from Gang-Yu Liu’s group.
Troy from Dean Tantillo’s group.
Josh from Jesus Velazquez’s group. After Josh left UC Davis with a Master’s degree, he ended up taking his life in 2022.
I profusely apologize, but I never got the name of the person that committed suicide from Alexi Stuchebrukhov’s group.
Since the deaths of these students, Ting Guo facilitated a graduate room for the graduate students to socialize in. Susan Kauzlaurich runs a mental health class, which I don’t even know what takes place. Dean Tantillo and I started a mental health working group to facilitate the needs of the graduate students. None of this is sufficient.
The first meeting of the mental health working group had more people show up than those that made regularly reoccurring appearances. Dave Goodin and Gang-Yu Liu showed up to the first meeting and then never showed up again. Alexi and Jesus didn’t even bother showing up to any of the mental health working group meetings after losing someone from their research group to suicide. After each meeting that Dean ran, he emailed everyone with the notes of the meeting and those that were in attendance.
None of the distinguished professors made regularly reoccurring appearances to the mental health working group. The distinguished professors are only distinguished because they are well known and not actually distinguished by their personality or character. If they were actually distinguished by their character and personality, then the issues that have shown up in the department would have already been proactively resolved.
I do not believe anybody should ever be called distinguished as this is a failed experiment to me. Being distinguished is another caste system that creates inequality amongst people. While I was at UC Davis only Dean and Marie were the only senate faculty that would go out of their way to acknowledge my existence, so even the senate faculty need to act more appropriate and welcoming to people in their department.
I do not understand how the deaths of E.J. Corey’s students made international news, and nobody has been notified about the deaths at U.C. Davis. I even emailed Chancellor May to discuss this and have only received an automatic generic response.
How is it possible that all these suicides took place and it didn’t make international news? What is going on in the department of chemistry at UC Davis such that this egregious behavior has been covered up?

I live on a swimming pond. My HOA treats it with diquat dibromide and endothall. Is this safe for my kids to swim in?
As the title says, the swimming pond is treated with diquat dibromide and endothall, as well as copper sulfate and chelated copper.
My kids swim in the pond almost daily in the summer. But I’m wondering if it’s really safe to swim in these chemicals, especially repeatedly in the summer and year after year?
I googled diquat and saw some alarming fact sheet about organ damage and such.
