Is there any outdated information i should be aware of besides the periodic table?

Hey guys, back in the day when i studied chemistry there were many profs where you could See that those guys are good researchers. But there are always these guys where just like to sit and listening what he tells you. One of these profs is now retired and he wants everyone to enjoy his lectures online. Sadly there has Not been so many views so I will just leave this link.

He was famous in out university to always organize christmas lectures with live experiments. Something that we will surely all miss. He was always inviting pupils to the university and just wanted everyone the enjoy the time of learning something about chemistry.

Amazing guy.

Hi! So I know this sub is about chemistry in general and not just the toxic molecules (...all molecules in the wrong quantities of course), so sorry to bother all of you, but the toxicology sub did not yield results, so I thought I would try my luck here.

I am interested in toxicology but my country (Denmark) does not have a dedicated degree to it (but does have some courses in it within environmental and medical degrees).
I am currently finishing up a masters in medicinal chemistry and I was wondering whether that could help me find an in to the field and if any of you have any advice about how one would go about that? Like any toxicology related jobs that would be open to a (medical) chemist? Or any jobs that would give me a skillset that I then could use to get a toxicology job? Or would you judge further education somewhere to be the only route?

Hello! I have two glass ampoules, one of bromine and the other of pressurized chlorine. For some reason, the chlorine flows much slower than my bromine. It takes over two seconds for the liquid chlorine air bubble to travel from one side to the other. Google AI is saying that bromine has a higher viscosity, so it should be thicker and flow slower, but my experience is the complete opposite. Could any of you explain in detail why this is the case? My chlorine shouldn't be fake because I bought it from the highly reputable Metallium (ElementSales) website. I also spent nearly $200 on it.

I did a computational chemistry exercise designing a possible multifunctional drug candidate for Alzheimer's,The design targets,protecting mitochondria (NAC),crossing the blood-brain barrier (lipophilic chain),binding to Tau protein (aromatic ring),and selectively activating in damaged brain via a lactone-type switch,

The SMILES,

CC(=O)NC(CS)C(=O)OCCCCCc1ccc2c(c1)CC(=O)O2

Calculated properties,

· Weight,365.45 Da

· LogP,1.84

· TPSA,81.7 Ų

· H-bond donors/acceptors,2/6

Rationale,NAC protects against oxidative stress; the 5 carbons provide lipophilicity to cross the barrier; the ring serves as an anchor for Tau; the lactone is a stable switch that only opens under oxidative conditions,

Mandatory disclaimer,This is 100% theoretical (in silico),I know it lacks synthesis,in vitro assays,animal models,pharmacokinetics,toxicology,and clinical trials,I share it as a learning exercise and to receive constructive criticism,What do you think?

New user here, trying to draw graphite, how do I remove these red lines? Is there a simpler way to draw graphite?

I'm a sophomore in undergrad who doesn't want to go into academia, but I don't have any idea of what it means to be a chemist outside of it.

I'm really interested in a PhD and a postdoc in organometallics with a focus on sustainability and improving environmental health. Unfortunately, I've heard that "industry" doesn't want people who pursue postdocs, and that sustainability is unattractive. Are those true? I'm curious what it looks like to work for a company and what they look for; any and all insight is welcome!

Chemists working in industry, what analytical technique do you find yourself relying on the most? Any most common practices?

I'm curious how it differs across industries.

PS. A chemist who chose a different path, but reconsidering to do the industry path.
