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-...

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/

Interested in #MOFs and #water in confinement? In the following publication we tried to derive the amount of differently ordered water species depending on the filling degree of the pores of MOF-74 analogues with the help of #IR spectroscopy. doi.org/10.1002/admi...
