This is to inform you that USP and UIC will be holding the 6th, fully virtual, qNMR Summit (see also https://www.qnmrsummit.com/); it will be a series of three 4-hour sessions, held on the three consecutive days, October 5-7.  The organizers would be happy to welcome you, your colleagues and young co-workers to join the event; it is free. This year, we will be awarding the first George Hanna qNMR Award – please see the recent review of his work.  Also, you may see the brief synopsis of the previous summits here. (Note: both articles are Open Access)

October 5th, 2021            7 am – 11 am ET
October 6th, 2021            10 am – 2 pm ET
October 7th, 2021            1 pm – 5 pm ET

Thank you very much, and we are hoping to see you at the Summit!

Kind regards,

Guido Pauli, on behalf of the 2021 qNMR Summit organizers

The method has gone through the round robin phase and internal committee review and is now open for public review. I invite the members of the ValidNMR community to review this draft standard and comment on it through the following link:

https://publicreview.csa.ca/Home/Details/4204

The opportunity for review will remain open until July 17, 2021. You will have to register using your e-mail address and create a password. 

I look forward to your comments on this.

Ian Burton.
