My students are titration savants
Today in gen chem the students did their first titrations and they truly outdid themselves. Out of 16 of them 13 of them looked like this Best group of students I've ever had

Advice on self-learning outside of formal education
HiI’ve already finished undergrad and currently in grad school (unrelated to science) and I wanted to self learn chemistry. I don’t plan on using it for a career or anything I just want to learn for learning’s sake and was wondering if anyone has any suggestions on introductory online courses or textbooks so I can start out with the basics. (Before you say just go to school I want to learn on my own time)

Insane amount of old pharmaceuticals we found in a university lab clean out
I don’t know what god forsaken cabinet they found all this in but this is by far the oldest stuff I’ve seen lab packing for universities

DMSO safety
I want to write this because I’ve seen a lot of questions on here that are from high schoolers ect.
DMSO can carry what it contains through your skin. It’s a fantastic solvent and that’s why that’s a concern. It’s a seemingly harmless thing to handle but its polarity makes it uniquely good at getting into your body. ((It takes what’s in it with it.)) things like essential oil on your fingers no big deal. Mix that amount of oil in DMSO and then skin contact and you have a toxicity problem. <<Don’t trust YouTubers cavalier attitude.>>
Long winded way to say, in chemistry it’s very easy to get in way over your head very fast. DMSO is not special in its hidden risk. Be careful out there.

Needing some random Chemistry Questions (and Answers) for my comic story
Hey y'all! I hope this is okay to post in this subreddit. I'm working on a story where one of the main characters is a Second Year Chemistry Major at a Community College, but the problem is that I know so little about Chemistry to write anything chemistry related and make it sound convincing. If anyone would be down, could y'all bombard me with a bunch of random ass chemistry questions and answers for me to use in my story? If not, then maybe showing me outlets to learn a bit more about chemistry or finding other ways to look for resources would be great! I thank y'all in advance!

TIL that Teflon was discovered because a gas cylinder that was supposed to contain tetrafluoroethylene suddenly produced nothing when scientists opened it.

Mixing sodium hydroxide to 200L of water and lime under thermal imaging.
At work we mix lime and caustic (sodium hydroxide) into water at a 4:1 ratio to increase ph in our drilling fluid. A full barrel (205L roughly) at 15 degrees Celsius will heat up to as high as 85 degrees Celsius with one bag of caustic. I got my hands on a thermal imaging camera to see the process but I caught something more interesting. You’ll see in the thermal image that the caustic beads go in cold but heat up substantially when they hit the water/lime mixture.

100 ns Molecular Dynamics Simulation of Ozempic (Semaglutide) Bound to the GLP-1 Receptor
Here’s a molecular dynamics simulation I ran of semaglutide, the active ingredient in Ozempic, bound to the GLP-1 receptor.
This is a 100-nanosecond molecular dynamics simulation showing how the peptide and receptor move and interact over time. Unlike a static crystal structure, MD allows us to observe protein flexibility, ligand motion, and changes in the binding environment.
GLP-1 receptor activation plays an important role in insulin secretion, appetite regulation, and blood glucose control, making it a major therapeutic target for type 2 diabetes and obesity.
The video is generated from my actual MD trajectory, not an AI-generated animation. It’s a visualization of the molecular motion predicted during the simulation, rather than a direct recording of molecules.
Thought this community might enjoy seeing what a drug–receptor complex looks like in motion!

What is your favorite chemistry from a movie or tv show?
We always harp on the chemical inaccuracies in shows and film, etc. But what are some examples of chemically accurate depictions of science and chemistry in media?
One that immediately comes to mind for me is The Martian scene where Matt Damon’s character is trying to create water using 2H2 + O2 —> 2H2O. Even the exothermic explosion part was reasonably accurate.

can i make it wight back?
it's a plastic windowsill that had been covered with transparent pies of soft cover and a some foamy cover. to prevent water spill from my plants so it wouldn't stain the windowsill. i suspect it has something to do with lighting. nover heard about plastic that changes calor in the dark
