TIL on @Wikipedia that the eminent Physical #Chemistry professor at the University of #Manchester , #MichaelPolanyi - who is the father of both Transition State Theory and #NobelPrize winning Physical Chemistry professor emeritus at the University of #Toronto , #JohnPolanyi - was one of 2,300 intellectuals on the #Nazis Special Search #List who if captured after an invasion of #GreatBritain were to be handed over to the #Gestapo. 🤔
In May, 2023, the #autobiography of FRANZ EFFENBERGER “From #Arenes and #Heterocycles to Bio- and #Nanotechnology” has been released in the wood-paneled Kekulé lecture hall @Uni_Stuttgart.

For #ArtAdventCalendar Day 2, #scientist Kathleen Lonsdale DBE FRS (née Yardley, 1903-1971) who solved the longstanding #chemistry conundrum of the shape of benzene. Here with her drawing of electron density for hexachlorobenzene (green) & model of hexamethylbenzene explore shape in different forms. Her husband said, “Before prison it might have bothered her to go to Buckingham Palace. Afterwards, Holloway or Buckingham Palace were all the same.” 🧵1

Great news for all chemistry students , AI will probably not replace you (yet), although generative AI can help in first year maths and physics questions, it struggles with chemistry. Not so strange maybe, it's less straight forward and exact.
At the same time GPT4 is amazing in analysing questions just from looking at a picture. #GPT4 #experiments #generativeAI #ai #chemistry
@SrRochardBunson Niobium was called Columbium in the USA, but not in Europe, for a while. Why?

How well can we measure, map, decode, and interpret brain activity? It depends on lots of factors. Dr. @russpoldrack explains in four short videos:
1. Measuring Brain Function
2. Mapping Mind to Brain
3. Brain Decoding
4. Interpreting Human Neuroscience Data
This is the 6th of 7 sets of videos from “A Beginner’s Guide To Neural Mechanisms”.
Early last century first #AdventCalendars came into use designed to help children to structure the waiting time until #Christmas. Now you are looking through doors to find out more. LiC opens 24 doors for you from today to #Xmas Eve through which you can view prominent chemists at work.

Unfortunately I was compelled and broke the no photography indoors rule at #GhibliMuseum. It was in the gift shop on the third floor & just some side table decor. The leftmost book was fake (wood, hollow inside lid) but the Organic #Chemistry book was real (and old: 1928 reprint of 1922 ©). Interesting - there was a chapter on vegetable alkaloids.

Even more exciting news soon… 😎
Researchers have developed supramolecular memristors for RRAM functions, demonstrating rapid resistance switching cycles of over 1000 and and retention time exceeding 500 seconds under ambient conditions with non-volatile storage capabilities. This paves the way for advanced data storage technologies.

Just skimmed this paper from the Jaramillo group: https://doi.org/10.1021/jacs.1c06212
Their conclusion: "imidazolium-containing ionomers intrinsically promote HER on Ag under CO2R conditions and have no measurable effect on CO2R to CO kinetics in contrast to expectations based on prior literature.”
Many papers use Sustainion™ membrane, seem to assume imidazolium must be present at cathode interface for good Faradaic yields.
So do we not need Sustainion™?

This is seriously cool - enzymes to break down plastic waste.
'One afternoon, she [Sintawee Sulaiman, University of Osaka, Japan] cut up some plastic packaging from a pair of headphones and left the shards in water overnight with some samples of LCC [leaf-branch compost cutinase enzyme]. By the morning, it looked different.
"The piece of plastic had some holes, or some breakdown," she recalls.'

Lars Onsager Norwegian chemist whose development of a general theory of irreversible chemical processes gained him the 1968 Nobel Prize for Chemistry was born #OTD in 1903.
His first achievement was to modify the Debye-Hückel theory of electrolytic dissociation, to take into account Brownian movement. He also was able to formulate a general mathematical expression about the behaviour of nonreversible chemical processes that has been described as the “fourth law of thermodynamics.”

Where do you start looking, and what tasks are you trying to achieve when you're reading?
Your feedback is invaluable and will help us to further develop our #journals tools and services for the benefit of the wider chemical sciences community.
Wow. Something I had never thought of. Fascinating.
Karl Waldemar Ziegler, a German chemist who won the Nobel Prize in Chemistry in 1963, with Giulio Natta, for work on polymers was born #OTD in 1898.
He is also known for his work involving free-radicals, many-membered rings, and organometallic compounds, as well as the development of Ziegler–Natta catalyst. One of many awards Ziegler received was the Werner von Siemens Ring for expanding the scientific knowledge of & the technical development of new synthetic materials.
Yesterday Mikhail Eremets delivered the UCL Bragg Lecture 2023, the story of "High Temperature Conventional Superconductivity" with a focus on hydrides, especially main group compounds like H₃S (sic) and many more.
Fascinating stuff, spectacularly difficult and beautifully fundamental. But work that takes us closer to one of the holy grails of physics: superconductivity at ambient temperature and pressure.
Speaking of neat papers, this was one of the coolest papers I read back in 2021.
It is such a nice piece of microbial chemistry, linking into sustainability and the circular economy, and shown in such a clear way too.
It should be free to read, so enjoy!

These are great opportunities with fantastic support to do great #research and there are several levels depending on career stage.
Come workout a great uni and do great science.
From the about page on a very helpful electrochemistry website: "I could have self-published this exclusively on Amazon and charged you $20, but I just read a Cory Doctorow book, so I decided to put this out there on the internet and rely on donations." - thanks for your influence, @doctorow !
Congrats to Tim Marshall for successfully defending his #PhD Thesis!
Tim's work focused on using MSMs as a platform for evaluating force fields and examining whether simulations can quantitatively predict how mutations affect folding stability, toward the prospect of simulation-based virtual screening for protein design. Several manuscripts describing this work are still in preparation, so stay tuned for preprints.

"The 2023 Ullyot Public Affairs Lecture was presented on Tuesday, October 17, by Nobel laureate Carolyn R. Bertozzi.
Bertozzi received the 2022 Nobel Prize in Chemistry for her role in founding the field of bioorthogonal chemistry, a term she coined, and for “taking click chemistry to a new level” with a set of chemical reactions that allow scientists to explore cells and track biological processes without disrupting the normal chemistry of the cell."

Newly minted #Nobel Laureate Louis Brus talked to us about what it’s like to win.
He has some advice for young scientists: “A good way to do it is you pick a subject that you know is important to technology, but there’s no understanding of the science at the present time…. That kind of problem, you can begin to take it apart and look to see what the basic steps are.” 🧵
