Rules of attraction: Strange chemical bonds that defy the textbooks
Our most fundamental ideas about how atoms and molecules stick together are changing. That is great news for creating new materials, but brings fresh challenges to understanding the world around us

Electron ptychography achieves atomic-resolution limits set by lattice vibrations
Two major problems that limit the resolution and interpretation of electron microscopy images are lens aberrations and multiple scattering. Chen et al. overcame these issues with ptychography, a technique that uses coherent scattering and multiple overlapping…

New study turns our understanding of ice upside down
As water freezes into ice, free-wheeling water molecules suddenly stop moving and begin forming ice crystals with their neighbors — but ironically, they need a bit of heat to do so, scientists recently discovered.
If you need some computational power, you may use the EMSL's (Environmental Molecular Sciences Laboratory) clusters for free and submit your NWChem jobs using the ARROWS API. It is a good excuse to learn the NWChem Quantum Chemistry package!

This popularity poll is based on an idea by Miquel Duran after a seminar given by Matthias Bickelhaupt (see http://www.marcelswart.eu/dft-poll/newsitem.pdf). By choice only 20 density functionals are given in the Primera Divisió, 20 in the Segona Divisió with 10 reserve places available (in Segona Divisió) for additional suggestions (mail these to marcel.swart (at) udg.edu). The functionals are ordered alphabetically (except for the reserve places that are ordered chronologically).
Please indicate for both the Primera Divisió and the Segona Divisió what you think of current density functionals. NOTE THAT IT IS POSSIBLE TO LEAVE EMPTY SOME OF THE FUNCTIONALS, either by not indicating anything or by clicking ("Vot en Blanc", "None Of The Above").
The poll will be open until Oct. 1 2021, after which the ranking of density functionals for the year 2021 will be made.

Unless something dramatic and unforeseen happens, the release of ORCA 5 has now been scheduled to take place on
Thursday JULY 1st, 2021
There will be an online event consisting of a short presentation and an Q&A session in the early evening of the 1st (probably around 5 pm, Central European Time). We hope that this allows as many users from overseas to take part in it as possible. The program will become available for download after the presentation.
On Friday July 2nd, we will have a day of detailed lectures going more in depth about the new features and the development that has taken place with additional room for questions and discussions.
We will post details about both online events here as soon as we have the organizational details under control. It will be similar in format to the last ORCA user's meeting.
We are looking really forward to this event and to all of you being able to work with, what we think is, the by far best ORCA there has ever been.
Take care!
Best wishes,
Frank (on behalf of an incredibly excited ORCA development team!)
