A material found in crab and shrimp shells ,usually thrown out by the seafood trade, was made into a gel and used as the working fluid inside a zinc battery. The zinc anode ran for more than 1,000 cycles at 99.7 percent Coulombic efficiency.

_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)

My highlights from this week’s #chemistry literature:
Light-induced piperazine functionalisation, selective FIZ1 degradation via thalidomide analogues and novel ketone homologation reaction. -
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=49304173I 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!).

Amazing paper by the Ed Tate lab with first (and co-corresponding) author Elena de Vita in JACS.
They discovered and developed a potent and selective covalent RAB27A/B inhibitor with a matched inactive enantiomeric control.

How can more stable antibody-drug conjugates be synthesized and translated into the clinics?
I am excited that we will host Christian Hackenberger for a @LED3hub Lecture, in which he will discuss, how his group is answering this question.
