Celebrating our Perspective ‘DFT exchange: sharing perspectives on the workhorse of quantum chemistry and materials science’

A stylised graphic showing a map of the world with various pins showing locations of the 70 authors of the Perspective article, overlaid on top of the graphic is an illustration of a conference table with people sitting around it, the conference table is a in the shape of a globe.

Featured on the cover of Physical Chemistry Chemical Physics Issue 47, and selected as a PCCP HOT Article, “DFT exchange: sharing perspectives on the workhorse of quantum chemistry and materials science” is already receiving a great deal of attention in the community.

 

The perspective, the first of its kind in PCCP, and the first such on Density Functional Theory (DFT), takes the form of a roundtable discussion featuring 70 authors, many of whom are active members of PCCP’s Advisory Board. The Perspective covers the history, present status, and future of density-functional theory (DFT), and adds up to an impressive 85 pages, with 777 references. Readers are encouraged to continue the exchange of views by contacting the authors.

 

Of the 26 total questions discussed by the authors, the topics ranged from the nebulous “What is DFT?” to the more specific “What format should workshops and conferences take in the future?”.

 

An example of the at times lively debate regarding DFT comes at question 3.8, “What has DFT told us about the real world?”, in which some authors such as Vincenzo Barone even question “what is the meaning of the “real world”?”.

A black and white image of Prof. Robert Jones Co-author Dr. Robert Jones (Peter Grünberg Institut, Germany) noted “I participated in (and survived) the struggle of a small number of scientists to convince the overwhelming majority of theoretical chemists that density-functional calculations could play an important role in chemistry,” and expressed his hope that this rejection of unfamiliar ideas would not be repeated in the density-functional community.

Many authors noted that methods for the teaching and sharing of information about DFT have diversified during the ongoing pandemic and spoke favourably of the new mixture of hybrid online and in person options for workshops and conferences.

The myriad benefits of this, including reducing carbon footprints, improving accessibility, and benefitting scientists with caring responsibilities, were all noted favourably during the discussion.

In the spirit of the project, we asked some of the co-authors of this landmark perspective to share their thoughts on its development and its unique round-table discussion format.

Co-author Dr. Simen Kvaal (University of Oslo, Norway) noted that many of the 70 authors are “world famous in the quantum chemistry community”

A black and white image of Prof. Tim Gould “It was a really pleasurable and unique opportunity to cover a breadth of DFT topics in a novel way,” said co-author Prof. Tim Gould (Griffith University, Australia), “The round table format forced me to think about some things in new ways and gave me a chance to see how others think, so was a valuable learning opportunity even prior to the final product.”

“I also consider it really valuable that the manuscript focused so much on theory, which doesn’t have the same “review”-style attention as DFT applications. From my personal perspective it was a good chance to clarify some misconceptions.”

Electron work functions look tough

Researchers in Canada have correlated the material properties of transition metals with their electron work functions using computational techniques.

The mechanical properties of a material are important, both for improving the fundamental understanding of the material itself, and for selecting and developing materials. Many scientists have studied how bulk properties relate to electron behaviour, using quantum mechanics, but such theories are tricky to apply.

A single hydrogen bond affects photophysics of chromophores

Green fluorescent protein (GFP) is a luminescent protein with a central chromophore and is used in biological imaging. By modifying the chromophore itself or the protein environment, the photophysical properties can be fine-tuned, yet until recently this has not been well understood. However, Lars Andersen (Aarhus University) and his group have developed a laser-action spectroscopy technique to enable the chromophore to be studied in a vacuum. This has revealed that a single hydrogen bond initiated a 0.5eV shift in the absorption spectrum of the GFP chromophore and highlights the importance of understanding the biophysics of  chromophores and how this can help in the development of new colour chromophores.

Rivers, Trees And The Many Structures Of Carbon Nanotubes

When a river comes up against an obstacle, it will split and flow around it before joining up again, thereby forming a central island. Similarly, carbon nanotubes can be grown to split apart and then re-join through the judicious use of metal catalysts. The authors of this communication, Hasegawa and Kohno, identified this phenomenon and coined the term ‘origami mechanism’ to describe it.

My river analogy is, however, a rather simplistic take on what they found. In order to draw a more accurate comparison I must turn to tree limbs. Imagine a branch with a linear split; there will be a hole in the middle, flanked by bare timber, and the bark will be effectively split into two halves with clearly defined edges. This would be equivalent to the carbon nanotube splitting into two ribbons with terminal edges, before reforming into an entire nanotube, as one might expect to observe.

However, this does not entirely tally with what Hasegawa and Kohno actually found. Their findings align more closely with the example of a wisteria, which has co-dominant stems, which grow apart and then re-fuse as the plant twists around itself as it grows. The difference here is that each of the stems, whilst apart, still retains a full covering of bark, as it is a distinct branch. Indeed, the authors found that the nanoribbons take the form of entire flattened nanotubes before they join up again.

Of course, the reality is more complex still, and you can’t beat reading about it in the authors’ own words, which incidentally, I strongly encourage you to do.

Zeolites net new carbon allotropes

Previously unknown carbon allotropes have been predicted by scientists exploring their links with well-known network topologies. The new structures are highly stable and transparent, some with larger optical band gaps than diamond.

Advanced computational techniques are leading the search for new forms of carbon and other group 14 elements. Now, Davide Proserpio from the University of Milan, Italy, and co-workers, have shown that fundamental network descriptors known about and catalogued for many years can help predict as well as classify and compare allotropes.
