Mathias Christmann

Congrats Christian and @PhosphorusFive! Happy for you to see this published!

With crystalization attempts is like playing the lottery: the more numbers you pick, the easier it is to win.

Don’t miss today’s online lecture by Timothy Noël @tnoel82 of @NoelGroupUvA (University of Amsterdam), hosted by @GDCh_aktuell and organized by the Liebig-Vereinigung. Details & free registration: gdch.app/event/from-bat… #FlowChemistry #ChemTwitter

@ewers_helge Thank you, Helge!

@ChristmannGroup Congratulations Mathias!

Impressed to see that the Accurate Mass (HRMS) Checker has already been used more than 1,000 times! Try it yourself: huggingface.co/spaces/Matchba… #MassSpec #ChemPython #OpenScience #HRMS

Beautiful blood moon over Berlin, captured from Drachenberg last night. #BloodMoon #Eclipse #NightSky #Berlin

@MartinTomanik @RiedelLab @fluor_crc1349 @ChemicalScience Thank you, Martin!

@ChristmannGroup @RiedelLab @fluor_crc1349 @ChemicalScience Congrats!

Our collaboration with @RiedelLab @fluor_crc1349 on photomediated C–H trifluoromethoxylation using is(trifluoromethyl)peroxide is now published in @ChemicalScience pubs.rsc.org/en/content/art… #openaccess #FluorineChemistry #RadicalChemistry #OpenScience

@g_laudadio @RiedelLab @fluor_crc1349 @ChemicalScience Thank you, Gabriele!

@ChristmannGroup @RiedelLab @fluor_crc1349 @ChemicalScience Beautiful paper! Congrats :)

Kids have a special eye for spotting the little things we often overlook. Challenge them to ‘find something cool’ and be amazed at what they discover 🔎 #NatureIsAmazing #PrayingMantis

Today the Long Night of Research takes place #lndw. At 22.30 h our experimental chemistry lecture takes place 😉 FU Berlin, Fabeckstrasse 34/36, 14195 Berlin Stay tuned !!!

Today, part of the team of the Institute of Chemistry and Biochemistry enjoyed great food 🍽️ and discussions at Luise before heading together to the university elections at #FUBerlin. Thanks to everyone who joined for the wonderful gathering! #CampusLife #ChemTwitter

2nd of the #Chemistry #Data Days of @NFDI4Chem : Mathias @ChristmannGroup gave a brilliant talk about checking mass spec data and its implication in #organicchemistry! Tool here: huggingface.co/spaces/Matchba… Paper: pubs.acs.org/doi/10.1021/ac… Thank you so much!!! @ACSPublications

Gemini 2.5 Pro's reasoning on domain-specific topics is amazing (and a bit scary, too). Tested it with today’s #Chemdl #182 (reaction scheme pic). The logical steps to the correct answer were spot on. Wow. #AI #LLM #OrgChem #ChemTwitter @GoogleAI chemdle.com

Well done, Gemini Pro 2.5: "Can you write a python script that generates a ball and stick model of a rotating water molecule that also show the two planes of symmetry and the C2 axis in a semitransparent fashion" #AI #GeminiAI #ChemPython #SciVis @GoogleAI

@DmitryPerekalin That looks like a type of error LLMs like ChatGPT, Gemini or Claude would find. It would be too much effort to create a hard-coded solution. Just too many possibilities. If you integrated API calls into the code, it could not be a free tool as API calls cost real $/€ per token

@ChristmannGroup For example it did not find typo like "zCfH3" instead of expected "CH3" in my document.

@DmitryPerekalin Sure, just don't have the time to do it. Yet, it very easy to integrate. For example, I have a function (experimental) that recalculates the yield. It is just that it generates too many false posititves, so I left it out.

@ChristmannGroup The idea is very cool, but it seems to check only some minor formatting errors, not really chemistry related ones. There is a lot to add.
