I say no to supporting a corrupt regime. But it seems like it could sneak up on an individual involved in any field.

This sounds like a fun way to learn about chemical bonding … Kudos to Professors Weiss, Wray, and Reed for not only seeing the potential but also for the hours it took to ensure success.

Turning Teflon-coated magnetic stirring bars to catalyst systems with metal nanoparticle trace deposits – A caveat and a chance It could be an unintentional effect to deposit metal nanoparticles on a simple Teflon-coated magnetic stirring bar. Rhodium nanoparticles, as an examp…

I too have been following 'stirgate'. I was especially interested in the article that suggested these little guys could be used as catalysts. www.sciencedirect.com/science/arti...

Electrons Are a Different Kettle of Fish And discover one of the densest places on earth, and some other fun things, with numbers!

Today, we see protons and electrons more like this…

JJ envisioned his atom as a positive sphere infused with negative charges. History does not tell us if JJ had that British delicacy, plum pudding, in mind, but his model quickly earned that handle. In 1911, Ernest Rutherford cast the electrons into orbit around a nuclear sun. Close, but no cigar.

When JJ Thompson discovered the electron in 1897, he rocked the scientific world. Physicists and chemists had labored for years under the notion that the atom was, as described by the visionary John Dalton, a single indivisible particle. How to accommodate these tiny negative entities?

A harbinger of things to come?

How can people who generate so much hate be surprised when it comes back to haunt them?

Perfect Complements Protons and electrons: Like peanut butter and jelly, a match made in heaven.

There are many occasions of symmetry in the cosmos. This post reveals the fundamental relationship that shapes the atom, and through it, the material universe.

Alchemy?! From medieval myth to modern reality

Did you know...
That the legendary physicist, Ernest Rutherford, is considered by some to be the first successful alchemist? Or that Glenn Seaborg, a pioneer in the realm of atom smashing, was the first to make gold via nuclear transmutation?

Good for you!

I read the book first. I agree... for that movie, the order doesn't matter. The movie omits the Rover roll-over, but not too much else. And the movie is long even with that omission.

That is a fun book and equally fun movie!

Who cares about isotopes? We do! Like it or not, isotopes have wormed their way into the fabric of our lives.

For a brief taste of how isotopes have distinguished themselves in chemistry, medicine and archeology see:

How stable isotope analysis reveals what ancient humans and Neanderthals ate Analytical chemistry can tell us what our ancestors ate thousands - or even millions - of years ago. Rachel Brazil gets her teeth into the evidence

Stable isotopes don’t always get the glory they deserve. They are often greeted with a heavy sigh in intro chem courses. But did you know that they can tell us what ancient hominins ate? #chemsky #chemistry #isotopes 🧪

There's nothing like a good logo Can we create suitable ones for each and every isotope?

Do you know that there are currently over 3,500 isotopic varieties of the 118 elements known to man? How can we possibly symbolize a specific one?

Nothing personal. Where would we be without physicians? Originally was 'physician who merely dabbled in chemistry' but had to stay under word limit.

Didn’t we all wonder about this at some point in chem lab? Nice to see it verified.

Good one!

Ohio citizens have voted twice to prohibit gerrymandering. The republicans ignore us.

8 chemists with disabilities who left their mark on history Scientists with disabilities ascended to the forefronts of their fields long before labs were accessible and civil rights were codified

Try to imagine chemistry without JJ Berzelius, who, after thousands of experiments, published the first precise list of atomic weights (1818). Yet Berzelius might have remained a mere physician had he never met Anders Ekeberg. Teachers can influence the course of history.

As for gold... Chapter 1, Section 1.8

Gold (Au) is labelled ‘observationally' stable. If gold were to suddenly display radioactivity, 'market volatility' might achieve critical mass! 💥😉 #chemsky #chemistry For more see mapofthechemicalworld.substack.com/p/as-for-gol... Written for the chemnovice and chemphobic

EA is defined as the energy RELEASED by adding an electron to an isolated atom. Mathematically, EA = E (neutral)-E(anion). EA is -6.8 kJ/mole for N.
The sign convention is a bear. Because of the word RELEASED, EA is opposite to delta E for anion formation. This can lead to a lot of confusion.

Brilliant!

When I was in grad school the professional glassblower was a rock star !

At the University of Cincinnati, in the late 1970s, German or Russian was required for the Chem major. By the time I finished grad school (1981) I believe that requirement had been dropped

Great to hear that there are jobs available! I started my teaching career at an liberal arts undergraduate institution (Denison University) and it was great fun to build a research program there!

Thank you!!

Willie is a national treasure

I am a PhD electroanalytical chemist. I would love to be added to the science feed! Here is a link to 6 of my publications. If this is insufficient evidence, please let me know! Thank you so much for your efforts. (I post under the name Paula Rossi, although my legal name is Paula Rossi Melaragno
