Exploring the limit of the periodic table:
The cover of this issue illustrates the search for an island of nuclear stability, a metaphor that has by now shifted towards glimpsing the mountains of enhanced stability on the horizon, their tops still concealed by clouds. See Smits et al, Nature Review Physics (2024). Cover design by Susanne Harris.

The Lennard-Jones potential Revisited: The Lennard-Jones potential can be extended to an inverse power series, resulting in simple lattice sum expressions for the equations of state of a solid, including harmonic and anharmonic vibrational effects. This is demonstrated for the rare gas elements from helium down to oganesson in the periodic table.

 |
Superheavy element chemistry: Exploring the chemical nature of super-heavy main-group elements by means of efficient plane-wave density-functional theory.
|
 |
Oganesson, a relativistic element: Three decay chains within the millisecond range were observed for the heaviest element in the periodic table, the 294 isotope of oganesson. This currently precludes any chemical investigation, but highly accurate coupled cluster calculations for the solid state reveal the unusual physical behavior of oganesson due to spin-orbit coupling in the 7p shell.

Change it up: A state-of-the-art quantum theoretical treatment reveals a detailed picture of the photochemical isomerization process from the nitrate to the cis or trans peroxynitrite. The influence of the aqueous solution is also considered.
|
 |
Electron and Nucleon Localization Functions of Oganesson: Approaching the Thomas-Fermi Limit. Calculations of the structure in oganesson, the element with the highest atomic number, reveal a uniform, gas-like distribution of its electrons and nucleons.

The attachment of a suitable "bouncer" molecule to the rim of a graphene pore
prevents the passage of the undesired enantiomer while
letting its mirror image through. A small difference in the geometry of the
temporary dimer complex, which is formed by the "bouncer" and the penetrating
molecule, is transformed into a significant difference for the transmission barrier.

The cover picture of J. Chem. Inf. Mod. shows T-C380, the first fullerene that does not admit any face spirals, partially
assembled until the point where the spiral fails. Below the fullerene, a schematic drawing
of the partially spiraled fullerene graph is shown. The T-C380 molecule was generated
using the computer program Fullerene using a generalized spiral algorithm discussed in
the paper J. Chem. Inf. Mod. 54, 121 (2014).

The cover picture of our Angewandte Chemie paper (2013) (designed by Cameron Smorenburg)
shows the link between Albert Einstein's special theory of relativity and the fact that mercury
is liquid at room temperature. An old problem is now solved: Monte Carlo
simulations using the diatomic-in-molecule method derived from accurate
ground- and excited-state relativistic calculations for Hg2 show that the melting
temperature for bulk mercury is lowered by 105 K, which is due to relativistic effects.

The cover picture of our Angewandte Chemie paper (2010) (designed by Roman Schwerdtfeger)
contains the words of Galadriel to Frodo in
'The Lord of the Rings' by J. R. R. Tolkien and continues: “But the mirror will also show
things unbidden, and those are often stranger and more profitable than things which we wish
to behold. What you will see, if you leave the Mirror free to work, I cannot tell.
For it shows things that were, and things that are, and things that yet may be.
But which it is that he sees, even the wisest cannot always tell.”
The large parity violation effects predicted for the chiral molecule
NWHClI from relativistic density functional theory are shown as a broken mirror image.
The energy difference of 0.7 Hz for the N-W stretching frequency conveniently lies in the
frequency range of CO2 lasers and may be revealed by future high-resolution spectroscopy experiments.

2941 (2010).

The cover picture of Angewandte Chemie (2003) shows Lake Matheson in New
Zealand, famous for its reflections of highest peaks Mount Cook and Mount
Tasman. In the macroscopic world mirror images are not perfect due to
imperfections in the mirror. However, at Lake Matheson the waters are often
incredibly still and it is difficult to tell the mountains from its reflection.
In the microscopic world mirror image symmetry is violated as well (parity
violation) and here it is even more difficult to distinguish between
enantiomers. High resolution spectroscopy gave so far no indication for the
breakdown of mirror image symmetry in molecules. The
(C5H5)Re(CO)(NO)I molecule shown in the cover picture
gives unprecedented large parity violation energy differences of 300 Hz which
brings us a step closer to the detection of such tiny effects. For more information see

42, 1293 (2003).
