Hey #chemsky

Need help. Has anyone ever taught an Industrial Chemistry course? What is the course content i.e. syllabus? I need to draft a new course on industrial chemistry. Can you please share with me your experience? Thanks in advance.

Celebrating winter here... without snow.
compoundchem.com Compound Interest | Chemistry infographics @compoundchem.com · Jan 6
Tis the season for winter storms in the Northern Hemisphere ❄️

Here's why snowflakes are six-sided, why ice floats on water, and the chemistry that takes place on ice crystals high in the atmosphere in this edition of #PeriodicGraphics in @cenmag.bsky.social: cen.acs.org/environment/...

#ChemSky 🧪
Infographic on the chemistry of snow and ice. Each water molecule forms hydrogen bonds to four other water molecules, creating a hexagonal structure and giving snowflakes their six-sided shape. A snowflake's shape depends on humidity and temperature when it forms. Ice crystals in clouds are perfect sites for photochemical reactions, which is why the ozone hole appears over Antarctica. Ice cores drilled in Antarctica and Greenland give information about Earth's past atmosphere.

My semi-annual PSA that if you're taking undergrad Thermo and it's got a stat mech/molecular focus, you may find my free online videos/materials useful. #ChemSky #SciSky 🧪

I was amazed at how wonderful a job you have done making these difficult subjects so accessible and easy to understand. You explain things so clearly and your lessons are extremely well structured. I just wanted to let you know how nice it is for someone to take the time to explain material instead of blowing through it and expect[ing a] student to retain it. Thanks for taking the time and putting in the effort to allow students a better learning experience. http://pollux.chem.umn.edu/4501 | University of Minnesota

"Approximately 70% of all available jobs are not published publicly, and anywhere from 50-80% of open jobs are filled through personal and professional connections"

honestly embarrassed to be associated with a professional society that spreads this kind of bullshit urban legend

It's #WorldBookDay today (but only in the UK & Ireland, bizarrely), so here's a reminder of the chemistry behind new and old book smells! www.compoundchem.com/2014/06/01/n...
Infographic on the aroma of books. The smell of old books is produced by the gradual breakdown of cellulose and lignin in paper. Type of paper and age of the book affect the compounds produced, which include furfural, vanillin and benzaldehyde. The aroma of new books is equally variable, the compounds causing it coming from adhesives, inks, and chemicals used for paper treatment. Many of these chemicals are odorless themselves, but can react and contribute to the release of aroma chemicals.

Great gifts.
Thanks a lot.

It’s hard to do photochemistry in a cloudy suspension. In SCIENCE this week, Ya-Ming Tian, Wagner Silva, Ruth Gschwind & Burkhard König pair up solid reagents that form a low-melting eutectic—an oily layer on water—that’s much better exposed to the light

Accelerated photochemical reactions at oil-water interface exploiting melting point depression
Melting point depression liquefies solid reactants to facilitate their photochemical coupling on the surface of water.

I am late to the party. Blue Sky has similar features to Twitter. Love it.
