My first MOF paper is back from 2009 and is about DUT-4/5, a nice collaboration between Dresden and Hamburg!

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:

Enjoy!

Thanks for the suggestion! Maybe that is the reason why he didn't response to my mail :-)

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!

I have been observing for some time that Springer Nature does not have a passion for publishing, but only a passion for profit.

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.

Thank you very much - I'm glad that you like it!

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.

Looks very interesting, but I think the link is broken, maybe you want to fix that?

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.

Sorry, ich möchte nicht zu unhöflich erscheinen, aber wofür taugt dieses Gedankenexperiment, das in sämtlichen Belangen (die Regel(!), die Koordinatorin kann keinen Stift finden(!), dadurch(!) gehen wichtige(!) Informationen verloren(!)] konstruierter nicht sein könnte?

Please share - our team is recruiting for a fully funded PhD position (Oct 2024 start, home fees only) on the use of electron crystallography to examine a range of properties in MOFs, from flexibility to guest binding (including crystal sponge work). Advert to come. Email me!
