French chemist Antoine Lavoisier died #OTD in 1794.
He is best known for his development of the law of conservation of mass, which states that mass is neither created nor destroyed in chemical reactions. This principle helped to debunk the phlogiston theory, which was a prevailing theory at the time that suggested substances released a material called "phlogiston" when they burned. He also made significant contributions in understanding respiration as a form of combustion.
British scientist Rosalind Franklin died #OTD in 1956.
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 authors have used a computational framework for automatic reaction discovery and kinetic model construction to explore the elementary reactions during methane pyrolysis. They automatically build the methane reaction network, going from ab initio molecular dynamics to kinetic modeling predictions.
Highlighting a neat paper in #ChemicalScience that might have relevance to #Glycotime (I think, and I hope since I am not within this area of research. Apologies if I got this wrong!)?
"De novo glycan sequencing by electronic excitation dissociation MS2-guided MS3 analysis on an Omnitrap-Orbitrap hybrid instrument"
When this one was submitted I was really interested in the use of the hybrid instrument. Very cool analytical work!
