A new tutorial on NMR simulation using MATLAB: this week I present methods for numerical propagation, then I show how to simulate an INEPT experiment with phase cycling and monitor the creation of 2-spin order #nmrsimulation #nmrchat https://t.co/RM6rwFKkuF via @YouTube

@ajerschow @global_nmr Interesting! The same concepts as those exploited in quantum rotor induced polarization I suppose?

[Quentin Chappuis Stern @quentinchapp]

@DaJo_1729 Hi David, nice work! I didn't understand the limitation regarding the cryoprobe. What's is it that you can't do and want to do with the cryoprobe?

@JabbourRibal @global_nmr Hi Ribal, nice to see you've joined Asif's lab! Deuterating the solvent does not decrease 1H DNP much for the asympol case. Your explanation is that the strong e-e coupling allows for long-range direct transfer. Does it mean that 1Hs on the radical aren't involved in DNP?

@global_nmr @lmis1_epfl @NergizSahin Hi, beautiful work! I'm interested to know what are the input and output signals and you have to feed in and read out from the chip? Is it only low frequency and DC?

Hi folks. I am about to delete my Twitter account because I feel like the ethics of this place are falling down too rapidly.

I wonder whether this tweet has any chance to be seen by anyone though... 🤔

See you (maybe) on some other platform

@DNPFred Oh dear! And of course, as a lay man, I could never expect such controversy..I maybe just had the feeling that the article was too hype...

Let's talk about the 2016 University of Hawaii-Manoa lab explosion as a case study in #LabSafety practices.

A few of the photos will be marked sensitive because a postdoc lost an arm in the explosion & there's blood at the scene.

This story is a warning to all researchers.

Don't miss the next AMPERE Café by @GROUP_AMPERE ! That's tomorrow at 8 pm CET. This time, the café will be a discussion about NMR instrumentation for the future with Christian Griesinger, Jan Korvink, Joanna Long, and Graham Smith. #NMRchat

[Quentin Chappuis Stern @quentinchapp]

@AMPERE_MR Do you think that a pedagogical paper where nothing new is presented and where the aim is strictly pedagogic is useful? That's what @Kirillsheb and I did. Give your opinion on @AMPERE_MR ! https://t.co/xlq0a1AIjO #NMRchat

[Magnetic Resonance @AMPERE_MR]

Discussion open for comments: Simulation of NMR spectra at zero- and ultra-low field from A to Z – a tribute to Prof. Konstantin L’vovich Ivanov https://t.co/SQK7IRXw0c

[Sumon Basak @ChemBasak]

What makes a productive #PhD student?

A. A SUPPORTIVE supervisor
B. SUFFICIENT salary each month
C. LIMITED working hours

That’s all needed for a PhD fellow to perform productively.

So happy to see this preprint out! @Kirillsheb and I wrote it to pay a tribute to our regretted mentor and collaborator Kostya. A tutorial paper on NMR simulation. This is a @AMPERE_MR paper so every one who wishes to comment or critique is welcome.

I am defending my PhD on Nov 10 at 2 pm CET. I'll present DNP on conductive polymers, spin diffusion measurements at low temperature and some hyperpolarized NMR at zero field. If you're interested, DM me to get the videoconference link! #PhD #NMRchat

[Quentin Chappuis Stern @quentinchapp]

@PatGiraudeau @arnabdeyju @ERC_Research @Sami_HMRlab @bruker Impressive by @arnabdeyju ! A nice piece for dDNP, which shows how to reach high repeatability

[Quentin Chappuis Stern @quentinchapp]

@maer @Sami_HMRlab Thanks Matthias!!

[Quentin Chappuis Stern @quentinchapp]

What a feeling! 4 years of work summarized in this document. Can't believe I'm holding my PhD dissertation in my hands! Thanks @Sami_HMRlab for great advice and support along the way. Now time for holidays! #PhDone

[Quentin Chappuis Stern @quentinchapp]

@SvenBodenstedt @Sami_HMRlab Thanks Sven :)

[Quentin Chappuis Stern @quentinchapp]

@mcdtayler @Sami_HMRlab I will!
