News from the space group diagrams project! Thanks to Eduardo Carrillo Aravena's tremendous support of the project, the diagrams for all hexagonal space groups are now complete as well! You can find the the diagrams here: crystalsymmetry.wordpress.com/space-group-...

Great ideas, but I lack the technical skills (I'm not a coder :-) and the necessary infrastructure (a website with MySQL support or similar). But if anyone would like to take over the MOF Universe project, I'm open to it... I will update your entry soon!

You are very welcome to make any suggestions for additional groups that should appear!

Of course! The MOF Universe is powered entirely by the groups themselves! PIs can submit their details either by sending me an email or, preferentially, by filling out the following form: forms.gle/GS43nKYBs9eg...

Beyond the Google map and Google spreadsheet the #MOF Universe now has an interactive 3D companion. MOF Universe 3.0 renders all 444 research locations on a rotating globe with colour-coded pins, and a built-in search. → Launch MOF Universe 3.0 here: crystalsymmetry.github.io/mof-universe/

I used the semester break to make some progress on the space group diagram project: now all space group diagrams of the trigonal crystal system (space groups no. 143 - 167) are complete! They are available as PNG, PDF, and PPT at: crystalsymmetry.wordpress.com/space-group-... Enjoy!

The #MOF Universe got a massive update with many additional information. We asked also for potential collaboration intentions - so have a look! Many thanks to everyone who took part in the survey and to the COST Initiative EU4MOFs for funding my work! crystalsymmetry.wordpress.com/mof-universe/

I have been observing for some time that Springer Nature does not have a passion for publishing, but only a passion for profit. #discover #mdpi #springernature #ResearchIntegrity the-strain-on-scientific-publishing.github.io/website/post...

I had absolutely the same experience with the renowned publisher Springer, but back in 2016, at a time when AI was not yet on the market. As you said, the main reason is profit: the copyediting is done by miserably paid people who are neither native speakers nor do they know the scientific subject.

I just published a slightly revised version of the original blog post, particularly concerning the hP47-α structure; it turned out that there was a small error in the SI.
