BREAKING:

Moldovan president Maia Sandu has held a speech to nation, warning that Russia is planning a coup d'état in Moldova, complete with attacks on government buildings and hostage-taking by men with military training working under the guise of “opposition protesters.”

Nikol Pashinyan refused to sign a declaration following the Collective Security Treaty Organization (CSTO) summit.

In fact, it means that the CSTO has collapsed completely.

Putin dropped his pen, Lukashenko is shocked.

We show here how ball-milling can be useful for sensitive reactions such as Negishi cross-coupling. Thank you @ChemEurJ for publishing this work.

Dear Wiley, it would be more decent to give chapter authors complimentary physical book rather than electronic access to their chapter via a reading app.

[Tibor Peňaška @PenaskaTibor]

@RadovanSebesta 👍

[Tibor Peňaška @PenaskaTibor]

Our chapter in the book "Chiral Building Blocks in Asymmetric Synthesis" (Wiley) 😉

[Radovan Sebesta @RadovanSebesta]

I am happy that the book Chiral Building Blocks in Asymmetric Synthesis containing our chapter with @PenaskaTibor on Chiral Heterocycles for Asymmetric Synthesis is ready to launch https://t.co/8141e9dOWu

[Tibor Peňaška @PenaskaTibor]

Our new accepted paper! 🙂

Thanks a lot to my boss @RadovanSebesta and other coworkers @CarnyTomas and @SamoAndrejcak! 👍
