SCAM ALERT. This is a fake conference that ripped off my and other people’s names to trick people into registering. There is no such conference that I or the others shown were invited or agreed to. We are working to try to get this fraud taken down from the web.

Guess what? It turns out scientists don’t like Nazis!

Illustration of the effect of dirty NMR tubes. The top shows a clean NMR tube and the corresponding "shim-map", which is very homogeneous. The bottom shows an NMR tube with a small black marker dot. The corresponding shim map shows a clear perturbation of several Hz around the dot.

Even the smallest contamination on an NMR tube can significantly impact your results. A dirty sample can lead to:

- Poor shimming and reduced sensitivity
- Potential contamination of the probe, requiring time-consuming maintenance

YouTube video by the bumbling biochemist My strategy for keeping track of assay data: logs, strategically-annotated figures, etc.

Here’s my strategy for keeping track of assay data. I started doing this in grad school and it’s still serving me well! youtu.be/-A1WoAY-aaE example template: bit.ly/assaylog #365DaysOfScience #chemsky #realtimechem #biochemsky

Yesterday, I attended the launch of @nadsn.bsky.social white paper "Towards a fully inclusive environment for disabled people in STEMM" #NADSNWhitePaper

Inclusion isn’t a burden—it’s the key to innovation #DisabeledInSTEM #RealTimeChem #ChemSky

The chemical structure of ’Clar’s goblet’, proposed in 1972 by Erich Clar. It's shaped like a microscopic bowtie

I'm so happy to see my @chemistryworld.com story on spin entanglement as the #1 most read online! 🥳 Keep reading, it's also the first solution synthesis of a super interesting structure shaped like a small bowtie 🧪 #ChemSky #RealTimeChem 👉🏽 bit.ly/4cqtkcW

A lot to unpack: a decade in high Z′ crystal structures Crystal structures that form with more than one molecule in the asymmetric unit (Z′ > 1) are a fascinating and important, if overlooked, aspect of crystal engineering. With the recent publication of t...

I'm getting to this a bit late, but I've just read this fantastic review of high Z' crystals/CSP by Paul Waddell in @crystengcomm.rsc.org .
Definitely a paper I'll be coming back to in the future:

A visualisation of the pKa scale of some common organic molecules in water. Original values taken from Dave Evans, DH Ripin & Hans Reich but all mistakes are my own. Now in portrait mode.

Re-inventing the wheel. Instead of a #ChemEd #Chemistry #ChemSky summary here is my version of a pKa (in H2O) scale. Values are taken from the wonderful Evans/Ripin & Hans Reich resources. If you want a table, I recommend these.

This was an attempt at a more visual representation of the data

Enjoy

This is the ONE TIME a large volumetric flask full of blue liquid is an appropriate choice of chemistry image: DeWitt worked with methylene blue (and trypan red)

Died #OTD 1928 Lydia Maria DeWitt: a pathologist who studied tuberculosis. She looked for dyes that would penetrate tuberculous lesions, especially dyes incorporating metal atoms such as copper, gold and mercury. She also worked hard to encourage women in scientific research #ChemSky #WomenInScience

0.25 cm³ of 1M copper sulfate is added to the iron staples and 2 cm³ of 1.5M sulfuric acid It is heated for 10 minutes. Can also use steel paper clips. This is the personal spirit burner (ethanol biofuel) hotplate.

Using filter paper in small-scale chem does not work. Filtering the reaction mixture through cotton wool in a Pasteur pipette. Copper particles and bits of iron are separated from the iron(II) sulfate solution..

Heating the filtered solution for 10 minutes on my personal spirit-burner, bio-fuel, hotplate.

Then leave to cool. The crystals form slowly, which might take longer than a lesson, but the results are very beautiful.

Helplines asked #CLEAPSS for an alternative to CuO/H₂SO₄ neutralisation reaction salt making for students to make salts. Not easy, but using ed/ox metal/acid reactions uses the same skills. This is iron(II) sulfate made from staples.

Pretty crystals were a surprise waiting for me when I collected my NMR sample today- shame it’s a known compound, but at least it shows me an alternative purification route to try when making this next time 😄

🔹🔷Fluorite Fluorescence!🔷🔹
George Stokes coined "fluorescence" in 1852 after fluorite, which glows blue under UV light. Fluorite is CaF2. Fluorescence is usually caused by yttrium, europium, or samarium impurities.
