Welcome back to another round of organic chemistry with MDMRN.
Once again, I've taken my molecular model kit to craft a new molecule. This one, frankly, I was able to craft using the pieces of the previous ones I presented before. While I didn't say it last time, the green represents a halogen, in this case specifically chlorine.
A hint is that the production of these types of compounds has been banned in numerous countries, including the United States. It was, historically, found in electrical transformers.
Can you guess what type of compound this is? Let me know in the comments!
So, we're going back to organic chemistry everyone!
After my first post with my molecular model kit showing an environmental contaminant, I decided to post up another.
This one is a semi-volatile organic environmental contaminant that is commonly found in coal tar, mothballs, and mixed into creosote for rail ties. That distinct "mothball odor" is this compound! Fun fact - a human nose can detect the mothball odor before most standard electronic detectors of organic odors / vapors.
Can you guess the compound? Let me know in the comments!
I don't talk about work here a whole lot, but I'm a chemical engineer by education and have been doing environmental engineering work for the past 17 years.
So, I have an organic chemistry molecular model kit that I have kept at work for years. I, periodically, make contaminants I've seen at various sites across my 17 year career cleaning up the environment.
Do you know what this chemical is supposed to be? Leave a comment below with your guess!
Happy birthday to chemist William Henry Perkin (1838-1907)! This #lino print ‘William Henry Perkin Discovers Mauve’ is about how the British chemist & entrepreneur made the serendipitous discovery of the 1st synthetic organic dye: mauveine.
Perkins entered the Royal College of Chemistry in London in 1853 when he was only 15, studying with August Wilhelm von Hofmann. 🧵1/n #linocut#printmaking#sciart#chemistry#syntheticChemistry#dye#histstm#chemist#FashionHistory#histchem#MastoArt
Happy birthday to chemistry trailblazer Marie-Anne Paulze Lavoisier (20 January 1758 – 10 February 1836), wife and collaborator of French scientist Antoine Lavoisier (26 August 1743 – 8 May 1794).
The Lavoisiers, working closely together, modernized and quantified chemistry and the scientific method, recognized and named oxygen and hydrogen, explained the role that oxygen plays in combustion, 🧵1/n
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 #womenInSTEM#linocut#printmaking#histstm
Born in poverty in Ireland, her mother left her father & brought the surviving kids to England when she was 5. She graduated in #physics with the highest score ever for a London University, with a BSc from Bedford College of Women in ‘22, & MSc from UCL in ‘24. Nobel laureate W.H. Bragg offered her a spot on his team at the Royal Institution, where she worked until she married in ‘27 & followed her husband research #chemist Thomas Lonsdale to Leeds for a job. 🧵3/n
Happy birthday to Marie Skłodowska-Curie (1867 – 1934, Polish-born, naturalized-French #physicist & #chemist. The contents of her lab glassware in my print appropriately glow-in-the-dark!
Marie Curie was the 1st woman to win a Nobel prize, the only woman to ever win 2 Nobel prizes, and the only person ever to win in two different sciences: #physics & #chemistry. She was also the 1st woman prof at the U of Paris, … 🧵1/n
Happy birthday Rosalind Franklin (1920 – 1958), #chemist & x-ray #crystallographer whose x-ray diffraction images were instrumental to discovering double-helix structure of #DNA, made important contributions to #carbon & #virus research, was 1 of the great scientists of the 20th century.
There's a joke amongst scientists that goes, "What did Watson and Crick discover?" "Rosalind Franklin's notes." But there’s more to the story.
This is my hand-printed linocut portrait of chemistry trailblazer Marie-Anne Paulze Lavoisier (1758 – 1836), wife & collaborator of French scientist Antoine Lavoisier (1743 –1794).
Working closely together, they modernized & quantified chemistry & the scientific method, recognized & named oxygen & hydrogen, explained the role that oxygen plays in combustion, …
