British scientist Rosalind Franklin died #OTD in 1958.
Her most famous contribution to science came from her X-ray diffraction images of DNA, particularly Photo 51, which provided crucial evidence for the double helix structure of DNA. Her photo was shared without her knowledge with J. Watson & F. Crick, who used it as a basis for their model of DNA's structure. Their work overshadowed her contribution, & she was not fully recognized for her role until after her death.
The temptation to make baked goods I can't/won't eat just because I have a fresh batch of aqua faba...
I almost typed aqua regia there, and yeah I need to make some of that too, but I don't plan to do that at home or use it in baking.
If you live nearish and want some of the good vegan/gluten (grain) free cookies let me know and maybe we can meet up so I have an excuse to bake them (someone gifted me another bag of almond flour a couple of weeks ago).
Can anyone think of a way to "quench" a HBTU/HATU/etc type coupling that doesn't involve adding water?
I've used MeOH, but I sometimes get MeOH esters which in at least one case proved to be inseparable from the desired amide product (I'm sure you know exactly how frustrating that was).
It might be possible to use <1 equiv of water with my conditions, but I'd really rather not since I directly load onto silica and do not do an aqueous work-up.
Interesting food chemistry story. Also implicitly a story about plant breeding. Many crops have different cultivars not just for different climates, but for different uses. #PlantBreeding#Chemistry#Food
British chemist and physicist William Crookes died #OTD in 1919.
He was a pioneer of vacuum tubes, inventing the Crookes tube which was made in 1875. This was a foundational discovery that eventually changed the whole of chemistry and physics. His experiments with cathode rays laid the groundwork for the discovery of the electron by J.J. Thomson. He is credited with discovering the element thallium, announced in 1861, with the help of spectroscopy.
Some egregious #AI art is now appearing in figures of peer-reviewed papers. But let’s take a moment to remember that #chemistry table of contents (TOC) graphics have always been completely unhinged!
These are all from the TOC graphics of real peer-reviewed papers in legit journals, most preceding the current AI hype cycle.
Black velvet #malachite display piece looking phenomenal in this light. Don't you just want to reach out and pet it like a precious little kitten? Very good looking piece.
"MIT chemical engineers have devised an efficient way to convert carbon dioxide to carbon monoxide, a chemical precursor that can be used to generate useful compounds such as ethanol and other fuels."
