_Hideki Shirakawa, Who Helped Turn a Lab Error Into a Nobel, Dies at 90_

“…someone accidentally added 1,000 times too much catalyst to the reaction to create the polyacetylene. Instead of getting a black powdery substance, as expected, the result was a silvery film that looked more like metal than plastic. Dr. Shirakawa was intrigued by the result and began studying the unusual material to better understand its properties.”

Most of my lab mistakes turned out to be mere blunders. I don't recall ever stumbling upon something *interesting* as a result… how about y'all?

Wait a lot of medival paintings are actual enciphered forms of storing information?

Like chemical formulas to avoid others copying their processes.

I think that may be cool as shit to look into more some day.

(Also some reactions only work because of impurities in the local source of the material, which makes it even harder to figure out and reproduce today)

A covalent bond is a chemical bond that involves the sharing of electrons to form electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs. The stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding.[1] For many molecules, the sharing of electrons allows each atom to attain the equivalent of a full valence shell, corresponding to a stable electronic configuration. In organic chemistry, covalent bonding is much more common than ionic bonding, where atoms are separate and merely associated by electrostatic attraction.

While saddened to hear of the passing of John Walters:
https://www.northfieldfuneral.com/obituaries/John-Philip-Walters?obId=49304173

I delight in the memory of his Analytical #Chemistry and Instrumental Analysis courses at #StOlaf College in #Northfield Minn. These had amazing labs using Commodore 64s that had build-in serial comm, GPIOs, and ADCs that could all be programmed in BASIC. We could create our own instruments!

He also would write up notes and photocopy them for the class at home in the middle of the night (in 1983!).

Have you ever employed #storytelling when writing your scientific paper? Sounds a bit fishy, but makes a lot of sense from a communications perspective.

There are plenty of storytelling methods. Here, Richard Brutchey explains the "Story Spine" framework and applies it to #chemistry:

🌿 A plant, a pigment, and skin that remembers. Why do fingertips hold henna stains so well?

Lawsone binds within keratinized skin and nail tissue, while the thicker outer layers of palms and fingertips help the stain deepen and linger. Across cultures, that chemistry becomes art, adornment, and memory.

✍️ Trace the stain through chemistry and culture:
https://www.theperpetuallycurious.org/henna-stain/

A quiet color deepens, lingers, and slowly fades.

💧 Clear water can still carry a quiet chemical history. Water softening changes what happens to calcium and magnesium, linking geology, chemistry, and treatment technology.

Color can begin in unexpected places.

In roots, leaves, bark, minerals, and even vats alive with microbes, natural dyes reveal how chemistry, craft, and generations of observation can meet in a single thread.
