A nuclear periodic table [PDF]

open access: yesFoundations of Chemistry, 2020
AbstractThere has been plenty of empirical evidence which shows that the single-particle picture holds to a good approximation in atomic nuclei. In this picture, protons and neutrons move independently inside a mean-field potential generated by an interaction among the nucleons.

Bonding, structure, and mechanical stability of 2D materials: the predictive power of the periodic table.

open access: yesNanoscale Horizons, 2021
This tutorial review describes the ongoing effort to convert main-group elements of the periodic table and their combinations into stable 2D materials, which is sometimes called modern 'alchemy'.

The periodic table in flatland [PDF]

open access: yesInternational Journal of Quantum Chemistry, 1996
The $D$-dimensional Coulomb system serves as a starting point for generating generalized atomic shells. These shells are ordered according to a generalized Madelung rule in $D$ dimensions. This rule together with an {\it Aufbau Prinzip} is applied to produce a $D$-dimensional periodic table.

Understanding Periodic and Non-periodic Chemistry in Periodic Tables [PDF]

open access: yesFrontiers in Chemistry, 2021
The chemical elements are the “conserved principles” or “kernels” of chemistry that are retained when substances are altered. Comprehensive overviews of the chemistry of the elements and their compounds are needed in chemical science. To this end, a graphical display of the chemical properties of the elements, in the form of a Periodic Table, is the ...

Educational Videogame to Learn the Periodic Table: Design Rationale and Lessons Learned

open access: yesJournal of Chemical Education, 2021
The periodic table allows to easily understand the chemical elements and predict the behavior of theoretical yet undiscovered new elements. Many memorization techniques have been used for learning the periodic table, yet serious games (i.e.

Single-Atom Catalysts across the Periodic Table.

open access: yesChemical Reviews, 2020
Isolated atoms featuring unique reactivity are at the heart of enzymatic and homogeneous catalysts. In contrast, although the concept has long existed, single-atom heterogeneous catalysts (SACs) have only recently gained prominence.
