Today in the classroom:
First year chem is finishing up an investigation on periodic trends, relating atomic radius and electronegativity to the nucleus of the atom. We'll intro electron arrangement (shell filling, etc)
Second year chem is reviewing for their atomic structure test tomorrow. Yesterday's practice test was okay - it brought up some things I'll focus on today to help clear up misconceptions.
Today in the classroom:
First year chem is doing a wonderful guided inquiry investigation of periodic trends based on an activity by Ann Baxley on ChemEdX [1].
Second year chem is taking a practice test over atomic structure. Given their work quality lately, I'm expecting it to kind of kick their tails. That's why it's practice.

Today in the classroom:
First year chem is doing some color-coding and research on properties of the main element families as an intro to the periodic table organization.
Second year chem is doing review and a practice test on the empirical evidence for the atomic structure. They'll take a test this week.
Today in the classroom:
First year chem student will either be doing their test corrections on atomic structure or reading an article on the aurora borealis and connecting it to the atomic structure.
Second year chem is still working with electron configurations and describing properties of atoms. We'll read an article on gold & silver and what wavelengths bump valence electrons to higher states, determining reactivity and color.
Today in the classroom:
We're heading to Chicago! We're taking about 80 students to the Griffin Museum of Science and Industry for the day. We'll leave during first hour to grab a train and then return around 6PM. It'll be a long day, but it's an annual tradition that goes really, really well and gives students a chance to do something new.
Students staying back will read about excited electrons in the auroras this week and connect it to atomic structure.
Today in the classroom:
First year chem is taking their atomic structure test. Pretty basic - subatomic particles, isotopes, and ions along with some written questions about the models we have and why we use models in general.
No second year chem class this afternoon because of an assembly at the end of the day.
Happy to finally have my last results of my PhD project published in #CarbohydratePolymers: Ionic agarose derivatives as polyelectrolytic additives for controlled drug release.
Key highlights:
⚗️ Developed anionic and cationic agarose derivatives with tuneable degrees of substitution.
💧 Integrated these materials into hydrogels and alginate micro beads to enhance drug delivery performance.
⏱️ Achieved sustained and low-burst drug release over up to 14 days with advanced kinetic modelling for accurate release characterisation.
This research contributes to the development of biocompatible and efficient drug delivery systems with customisable release profiles. It now marks an end of this part of journey, where I have learned so much!

“In general, from 2020 onward, a strong rise in space waste mass influx to the #atmosphere can be seen. ... This indicates a substantial risk of long-term adverse effects on the atmosphere such as #ozone depletion, radiative effects and changes in #cloud formation, if no action is taken. Research is urgently needed into the atmospheric accumulation, #chemistry, and general atmospheric effects of specific elements.”

two weeks ago I asked about an #openscience #chemistry journal. Thank you, to everyone who coined in. There seems to be sufficient interest and a lot of great comments came in. https://social.edu.nl/@egonw/115429360431414258
The first step seems to be to establish good editorial guidelines. These explain what is expected of authors and reviewers. A community has to agree on this first.
I think this may also be why we ended up in the situation where we are. Lots of citations, but low reproducibility.
More soon!

Happy birthday to Marie Skłodowska-Curie (1867 – 1934, Polish-born, naturalized-French #physicist & #chemist at work in her lab. The contents of her lab glassware appropriately glow-in-the-dark!
Marie Curie was the 1st woman to win a Nobel prize, the only woman to ever win TWO 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, 🧵
