A label of Mg food supplement saying that it is Extend-Release.

Let me get is straight - you are directly and proudly saying that you are selling a brick, right?

Yes, they are selling a brick, MgO is an excellent material for refractory bricks.

A fragment of a crystal structure with fluorotris(perfluorophenyl)borate and disordered dichloromethane.

All users except one in last couple of week:
- I have a great idea - I'll take this molecule and coat it with fluorine. (in various ways)

In addition to authorships being for sale, it is one of my favorite kinds of cargo cult papers. No, you cannot possibly predict "sensing performance" with DFT. Yet some journal has/will publish this slop.

So, your "High Absorption Magnesium" food supplement is not soluble in the mixture of concentrated nitric, sulphuric and hydrofluoric acid. I have two questions:

1. What exactly you added in it?
2. How I suppose to make ICP analysis?

A post from the Ames history museum Today in Ames history: the chemical and physical laboratory building and Iowa state burned down on March 25, 1913. It was located near where Pearson Hall is today. The building was originally constructed in 1870 and added onto several times. It was completely destroyed in the fire. The chemistry department had needed a larger building for more than a decade, and the fire finally spurred an allocation for a new Chemistry Hall. It opened in 1914. In 1973, the building was named Gilman Hall.

Happy Old Chemistry Building Burning Down Day to all who celebrate #chemchat #chemsafety

EA-3167 - Wikipedia

Ever hear about the drug EA-3167?
It was developed by military contractors at Edgewood in the 60s, but it's no mellow yellow folks

A couple hundred MICROGRAMS and you'll catatonically trip out of your mind for a WEEK

EVEN AFTER 6 MONTHS, test subjects were mentally unwell

Ladies and gentlemen, place your bets on what I’ll find in these bottles.

Do not have a slightest idea for the moment, but I expect a lot of fun for less than 30 euros. Answers will come somewhere in two days. 5 test objects in total.

Chart of CO2 levels from Aranet monitor for Sunday March 22. levels fluctuate mostly between 500-900 ppm throughout the day-all in the „green“ color coded zone

FYI to #ACS #ACSspring2026 attendees, the Georgia World Congress center has really good ventilation!

The CO2 levels throughout the whole day stayed in the green zone on the Aranet monitor.

#chemchat, can you spot what is wrong with this certificate of analysis?

Meme Panel 1: "biologists will be like this is a very simplified diagram of a mammalian cell", followed by a complicated pic showing all the various aspects of a cell, numbered and with detailed labels Panel 2: "chemists will be like this is a molecule", followed by the structure of n-butane, ie: four points connected by three lines, ie: basically a zig-zag with 120-degree angles

Dunno source, but LOL #chemchat
