- Green Solvent Selection Tool by the OPEG group at the Department of Physics at Umeå University. Written in Python. With publication and source code.
[I will add more dashboards here as I (re)-discover them].
This is just awesome! An open source magnetic stir heating plate!
Dr Erik Johansson (Uppsala universitet) ger i denna korta video en beskrivning av kvantprickar med anledning av årets nobelpris i kemi.
Really nice work by Steve Byrnes. Very useful.

This is a nice and useful summary of electrochemical cell potential relationships.
It appears to be part of a larger collection of lectures and slides from Mississippi State University.

An IUPAC project (apparently in collaboration with CODATA and CIPM, which makes it very official).
- Units of Measure for Humans and Machines, released in Oct 2020
- Digital Representation of Units of Measure in Chem. Int., vol. 42, no. 4, 2020, pp. 36.
- What's the future of digital chemical units?, presentation by Stuart Chalk at ACS Fall in Aug 2021.
- Stop squandering data: make units of measurement machine-readable in Nature vol. 605, 2022, p. 222-224.
Other IUPAC projects on digital standards. Of particular interest to us are Machine-accessible periodic table and Development of a standard for FAIR data management of spectroscopic data.
With the increasing focus on open science and FAIR data, IUPAC is focusing effort toward the development of digital standards for chemistry. Its Committee on Publications and Cheminformatics Data Standards (CPCDS) has compiled this page with IUPAC resources.
A commendable effort!
Video by Royal Society of Chemistry, from Jan 2022.
In this video produced by the American Chemical Society, George Zaidan does a great job presenting a short but fundamental explanation of what an electron is and why that matters (pun intended).
I can really recommend!
Via Physics World.
There's a chemistry tree.
Looks like good fun, and the data that makes up the genealogy is shared under a CC-BY license (bulk data export requires contacting the site admin), but I have found no mention of the license for the code of the website/project.
Their FAQ is very informative.
− Kan vi producera färg av koldioxid? Svaret är ett rungande ja! Det var beskedet från Anna Berggren hållbarhetschef, Perstorp, när hon beskrev företagets planer på att bygga en anläggning för att samla in koldioxid och tillverka metanol av den.
Inspelning från IKEM:s och Kemisamfundets seminarium om vad som förenar Perstorp och Mars-resor.

- Alexis Bohlin, forskare vid Luleå tekniska universitet.
These videos were produced for the National Science Foundation by the California Institute of Technology in the 1950's.
Via 3quarksdaily.
Pretty neat. Also
the band gap in ordinary water is about 7 eV
Good to know!
The Materials Project's mission is to accelerate the the discovery of new technological materials through advanced scientific computing and innovative design tools.
To use Materials Project's API, pymatgen may be easiest.
I am not aware of a similar API wrapper for R.
Taylor Sparks has produced a number of videos related to the Materials Project, such as Materials Project API example using pymatgen and Materials data repositories.
Lake Retba in Senegal is the world's second most saline body of water, thanks to being cutoff from the ocean some 50 years ago.
Workers produce 60000 tons of salt per year by harvesting it from the lake bottom and sun-drying it before adding iodine and filling it into bags for sale.
"How 60,000 Metric Tons of Salt Are Harvested from One of the World’s Saltiest Lakes", by Eater
For comparison, the world annual salt production (not only from lakes or oceans), is around 280 million tons. The oceans contain a virtually inexhaustible supply of salt.

Also has built-in functions for producing Wikipedia ChemBox for the structure (cool!).
