General position diagram of space group R-3c (no. 167)

General position diagram of space group R-3c (no. 167)

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!

Springer Nature Discovers MDPI โ€“ The Strain on Scientific Publishing Home page for the paper โ€˜The Strain on Scientific Publishingโ€™ by Mark A Hanson, Dan Brockington, Paolo Crosetto and Pablo Gomez Barreiro

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.

IR Spectroscopic Studies on Water Confined in an Isoreticular MOF Seriesโ€“Influence of the Metal and Linker Functionality Mono- and bimetallic isoreticular MOF-74 analogs with different ratios of Mg2+ and Ni2+ and linkers of different sizes and functionalities are synthesized and loaded with water.

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.

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

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!
