In honour of , I finally organised some old code of mine into an R package. Please welcome `periodicdata` to the world
github.com/chepec/periodicdata
It's mainly concerned with collecting and organising the properties of the elements, but also takes a dab at plotting them.
(It's probably most useful if you already use R and ggplot2, but feel free to try it out in any case).

The "International Year of the Periodic Table" is well under way, and it feels like something new is posted daily. It's great fun!
This "visual history" by Science magazine does a good job of visualising the many shapes the table has taken so far. vis.sciencemag.org/periodic-ta
(The animations didn't work properly in Firefox ESR, but Chromium seems to handle them fine).

@arjen @dantheclamman Correct, and they even encrypt the database created by the "Backup" function. Only way around it is to maintain a v1.18 install somewhere (I have it on my Win10 virtual machine, pinned to that version using Chocolatey) or maybe this very complicated approach (not mine): eighty-twenty.org/2018/06/13/m

Quit using Mendeley people!

They started encrypting your database so you cannot easily move it over to other tools any more.

See:

That link also helps you saving your data before it's too late.

(Elsevier are a bunch of crooks, blocking interoperability one-way and not the other. Almost as bad as Google blocking uBlock for your safety...)

@Canageek I feel you. I haven't used it in that manner myself. But I think it should work between two local folders. Although I've been googling it right now without much success :-(

@Canageek May I suggest unison? It really shines for two-way sync between computers, but it can handle two local roots as well. FOSS, of course.

@drb Hi! I did not have any issues. Pandoc was the Markdown engine that Jekyll used, and jekyll-scholar just took hand of the references and such.
I'm writing in the past tense because I've since switched the site to Hugo :-) Very much faster site rebuild time, and only slightly less flexible but I expect that to improve as Hugo matures.

@mskblackbelt @invaderxan @GIMcGrew Well, that's great news. I read the FAQ and the Terms, and it seems they are still setting up a governance board for it, but preprints will be published using a CC-BY licence (author's choice), and the preprint service will allow data mining via API (not completely finalised yet). The preprints will even support rudimentary version tracking. This doesn't sound too bad. We should help spread the word!

@invaderxan Yep, ACS is also a driving force behind the legal process against Scihub. They are definitely not an example of scholarship in chemistry for the future.
Creating a working preprint server for chemistry should be the easy part, but uptake among chemists is the tricky bit, I reckon.

Unpaywall is a handy little open source project, available to use as a browser extension, which makes it easier to find open access copies of journal papers.

I just thought I'd share this here for those who may need it. I find it very useful!

I recently learned about hematene. It's a 2D material similar to graphene, and made in the same way, except instead of carbon it's made from α-Fe2O3 (hematite). It also looks like it has excellent potential as a photocatalyst.

Makes me wonder what other 2D materials we might have yet to discover.

@invaderxan Yeah, that could very well be contributing. This absence is problematic, and ACS (of all orgs) actually launched a chemistry preprint server in late 2016, but I've never heard of it since. In my opinion, a preprint server would be very useful, but some org with open access credibility should probably operate it.

Interesting study by Wikimedia Foundation into the availability of Wikipedia's references across different subjects. Sad to see that Chemistry ranks very low, with a high percentage of pay-walled references.

Should also link to the twitter thread: twitter.com/Wikimedia/status/1

@jpmitchell There's also Andstatus for Android. Tusky looks nicer than Andstatus, but the latter supports multiple backends (Twitter, Mastodon, Gnu social).
