Listening to Material World audiobook. Written and ready Ed Conway.
Sand, salt, iron, copper, oil and lithium. They built our world, and they will transform our future. These are the six most crucial substances in human history. They took us from the Dark Ages to the present day. They power our computers and phones, build our homes and offices, and create life-saving medicines. But most of us take them completely for granted.
Resistance is futile: you will be protonated!
Super acids are fun, if you like destruction.

Painting a periodic table has been on my list of things to do for a long time. So, here it finally is. The first photo shows the luminescent paint for the luminescent elements. The second photo shows the mica paints I used for the precious metals and the crowns for the noble gasses.
The Royal Society of Chemistry (UK) has a really nice vision statement for creating a positive scientific culture, covering areas like inclusion and #diversity, ethical practice, #openscience, and recognition of science and scientists. Not just applicable to #chemistry!
The Webb Telescope has confirmed the presence of recent carbon dioxide on the surface of Jupiter's frozen ocean moon #Europa.
Thank you to everyone who is following our journey on Twitter/X.
Your interest and interactions have helped tremendously of late, whilst I've travelled through a couple of health issues – I'm on the road to recovery, and we're still aiming to GO ELECTRO! 😎
At first you might think this is a niche and nerdy description of a piece of apparatus used by organic chemists to purify their samples: the kugelrohr or bubble tube. Elegant, simple, fast and widely used. But it conceals a dark dark tale and a warning about the perils of our times. Beware! This stuff could happen anywhere. #ClassicKit #chemistry https://www.chemistryworld.com/opinion/4018107.article
🤔 Make your predictions for the 2023 Nobel Prize in Chemistry
`Pyruvic acid (IUPAC name: 2-oxopropanoic acid, also called acetoic acid) (CH3COCOOH) is the simplest of the alpha-keto acids, with a carboxylic acid and a ketone functional group. #Pyruvate, the conjugate base, CH3COCOO−, is an intermediate in several #metabolic pathways throughout the #cell.`
Chemical engineers have designed a fire-safe fuel that ignites only with the application of electric current. Since it doesn’t react to flames and cannot start accidental fires during storage or transport, it is a “safe” liquid fuel.

We asked 7 laureates: Did winning the Nobel change your life?
Finally tracked down at least part of the problem that has been draining my N2 tanks. After nearly 20 years of use, this pigtail needs replacing. This is totally a plug for Leak Bubbles - Yellow! from Comstar that solidify. Way better than snoop for tough-to-fine leaks #chemistry #chemiverse #highpressure #pui #proflife
Had a nice surprise the other day when Google Scholar informed me the very first paper I ever wrote now has over 1000 citations. Does this mean I have been on a downward spiral ever since? I hope not 😅 Big thank you to my mentors and students. I'd never have dreamed people might find our work useful and, I'd like to think the best is yet to come.

Is there anyone in Canada who could do with some 13-C labelled CO or acetylene? There's some that will have to disposed of in Alberta. Spread the word. #chemistry
In this Perspective, Paul J. Lusby et al discuss the key features that make an effective coordination cage catalyst, linking structure to activity and selectivity. The authors also provide an outlook for this area, reasoning why coordination cages have the potential to become the gold-standard in (synthetic) non-covalent catalysis.

I just got a super strange e-mail today from one of the two candidates for the #ACS presidential elections, and I wonder why I got it? I unsubscribed and it says it was the "ACS member list", but what is that? I can't find it in my personal ACS e-mail preferences. Did ACS give my personal data to a third party? #AmericanChemicalSociety #chemistry #chemiverse
Latest publication, joint book chapter with Neil Robinson "Recent Applications of Benchtop NMR Spectroscopy and Relaxometry". We give a background to the methods and show the versatility of applications off these techniques. May sound a bit technical but we've tried to make it accessible to as many people as possible.

Lets talk about chirality. And what those asteroid samples could teach us.
Chirality is the "handedness" of molecules. This is a big deal in #astrobiology
If you have a central atom of a tetrahedron and four different things poking out of it, there are two possible orientations.
(Try this with colored gumdrops. Geologists may get to lick rocks, but chemists get to eat their gumdrop models.)
#Chemistry thread time!!!
@RickiTarr I’m here because my strongly pro-science and anti-fascist tweets got my @ChemicalEyeGuy #birdsite :birdsite: account with 1,000 followers ‘permanently suspended’ - and without warning - on the day of the #2022election. #Mastodon is where other respected #science tweeters were headed, so I joined the #TwitterExodus and here I am. I like the strong artistic vibe, and the growing #chemistry community, but I’d like to see more journalists and political cartoonists.
The #SciArtSeptember prompt adornment made me think of fashion, “mauve madness” & William Henry Perkin (1838-1907)’s serendipitous discovery of the 1st synthetic organic dye: mauveine.
Perkin entered the Royal College of Chemistry in London in 1853 at 15, studying with August Wilhelm von Hofmann who hired him as his assistant in 1855 & had him working on a series of experiments to try & synthesize quinine, used to treat malaria.

I still cannot understand why this #chemistry paper (https://link.springer.com/article/10.1186/s13321-017-0196-0) is cited only once
Frederick Soddy died #OTD in 1956.
He was an English radiochemist who explained, with Ernest Rutherford, that radioactivity is due to the transmutation of elements, now known to involve nuclear reactions. He also proved the existence of isotopes of certain radioactive elements.
He received the 1921 Nobel Prize in chemistry for his research in radioactive decay and particularly for his formulation of the theory of isotopes. via @wikipedia
Life on a faraway planet — if it’s out there — might not look anything like life on Earth. But there are only so many chemical ingredients in the universe’s pantry and only so many ways to mix them. A team led by scientists at the University of Wisconsin–Madison has exploited those limitations to write a cookbook of hundreds of chemical recipes with the potential to give rise to life.
Art and science are often seen as opposites, but are they? Join SFU Chemistry professor @vancew for a talk about the often blurry lines between the artist and the scientist at his Café Scientifique talk on Zoom, Tuesday, September 26: https://events.sfu.ca/event/36759-cafe-scientifique?_gl=1*lfmqa2*_ga*MjAwNDc0OTg3NC4xNjg2NjEzNDIy*_ga_R4BCVYL1QF*MTY5NTE0ODMzNC4xNjkuMS4xNjk1MTQ4NjI2LjU5LjAuMA&utm_source=twitter&utm_medium=social&utm_content=57a97829-44f9-4b41-a39f-ea44c3175561 #sfuscience #sfu #chemistry #sciart #scicomm #cafescientifique #scienceoutreach #SFUChemistry
Inspiration for today's #inkyDays drawing, came from an abstraction of atomic bonding angles.
#SciArtSeptember 16th is ochre, which is an earth pigment tinted with iron oxides. It is a far superior alternative to lead oxide (bottom left), which is various shades of toxic to us.
Photographs are of evaporated waste jars from back when I was a #chemistry lab tech that I thought were pretty.
If you're familiar with any of my work, you already know that I like to work with science and math, and that I also like to play.
In this piece, I was working on an interactive Periodic Table of Elements. Then I had fun with it, making the 'cells' drift down. I called the piece 'Elemental Snow'.
#Neptunite is one of a few calcium-free titanium silicates (incl. benitoite). Seems like an obscure fact but:
To standardize a microbeam analysis (like laser ablation ICPMS), we need a mineral with a known composition, lots of titanium and silica and no calcium, which has an isotope at mass 48. Neptunite and benitoite are perfect for this.
#SciArtSeptember Day 13: Carmine
The cochineal lives and reproduces on prickly pear cacti. They coat themselves and the #cacti in a fuzzy white coating. After being harvested and dried, carminic acid is extracted but usually
further stabilized into carmine (lake) with aluminum salt. It is also known as E120, Natural Red 4, Crimson Lake, and Cochineal Extract.
@L_howes I wrote up a first blog post about my experiences. Moving from one session to another indeed works a lot better online. I've always been a bit more of a CINF person than COMP, and also this time, did not find the COMP sessions very attractive. Well, that's not entirely true, it *is* attractive and interesting, but it just doesn't excite me enough
@L_howes okay. Since posts spread a bit more slowly here on #mastodon (slow is good), and not everything is visible on every server (community standards are essential), I wasn't sure I was receiving all the online #ACSFall2023 vibes.
Also, you can have a look to see who is participating in Miguels education community @mguhlin
For #SciArtSeptember day 9: heart, it’s trailblazing American #biochemist Marie Maynard Daly (1921-2003), 1st Black woman to earn a PhD in #chemistry in the US! She made important research contributions to the biochemisty of the cell nucleus & cardiovascular issues & our knowledge of the chemistry of histones & protein synthesis. She published original research establishing that….
Researchers use stem cells to generate human neurons resembling those in the brain that control breathing during opioid reactions, for eventual chip devices to test overdose therapies.

When your #chemistry lecturer hands out a big teddy bear for you to squeeze in case you get anxiety attack from big scary Schrodinger equation being solved for hydrogen.
Happened in my class today.
I blew >1 hour today killing four unlabelled ampoules of ukn liquids each ~100-200 mls. The first three were lively but ok. The fourth was different; it hit the water angrily, igniting instantly. After getting hold of some ice I alternated pouring with fire, and then pouring again until the whole lot was gone. It was some kind of aluminium alkyl.
I admit that I got a bit sweary…
Lesson: label your goddamn stuff securely, and deal with it before you finish your research project! #Chemistry
