We had to memorize the Periodic Table *AND* every American State name and State Capital.
When I met an American kid, I said, “You guys are so lucky. You only have to memorize our ten Provinces and Capitals.”
“We don’t study anything about Canada in school…"
WTAF!? 😳
That's when I realized Canadians were different from Americans. 🤣

Research status of the Mendeleev Periodic Table: a bibliometric analysis
In this paper, we present a bibliometric analysis of the Mendeleev Periodic Table. We have conducted a comprehensive analysis of the Scopus-based database using the keyword "Mendeleev Periodic Table". Our findings suggest that the Mendeleev Periodic Table is an influential topic in the field of Inorganic as well as Organic Chemistry. Future researchers may focus on expanding our analysis to include other bibliometric indicators to gain a more comprehensive understanding of the impact of the Men…

Significantly Enhanced Vacancy Diffusion in Mn-containing Alloys
Manipulating point defects for tailored macroscopic properties remains a formidable challenge in materials science. This study demonstrates a proof-of-principle for a universal law involving element Mn, significantly enhancing vacancy diffusion through an unprecedented anomalous Friedel Oscillations phenomenon, across most metals in the periodic table. The correlation between Mn-induced point-defect dynamic changes and intrinsic macro-properties is robustly validated through the first-principle…

Balian-Bloch Wave Invariants for Nearly Degenerate Orbits
This paper is part I of a series in which we aim to show that the singular support of the wave trace and the length spectrum of a smooth, strictly convex, and bounded planar billiard table are generally distinct objects. We derive an asymptotic trace formula for the regularized resolvent which is dual to the wave trace and contains the same information. To do this, we consider a class of periodic orbits which have nearly degenerate Poincaré maps and study their leading order behavior as the de…

Revealing the regularities of electron correlation energies associated with valence electrons in atoms in the first three rows of the periodic table
Electronic correlation is a complex many-body effect and the correlation energy depends on the specific electronic structure and spatial distribution of electrons in each atom and molecule. Although the total correlation energy in an atom can be decomposed into different components such as inter-orbital and intra-orbital pair-correlation energies (PCE), it is generally believed that the PCEs in different atoms cannot be the same. In this work, we investigate the correlation energies of the atom…

Frustrated Magnetism, Symmetries and $\mathbb{Z}_2$-Equivariant Topology
A novel lemma in $\mathbb{Z}_2$-equivariant homotopy theory is stated, proven and applied to the topological classification of frustrated magnets in the presence of canonical time-reversal symmetry. This lemma generalises a result which had been key to the homotopical derivation of the renowned Bott-Kitaev periodic table for topological insulators and superconductors. We distinguish between three symmetry classes $\mathrm{AIII}$, $\mathrm{AIII/BDI}$, and $\mathrm{AIII/CII}$ depending on the exi…

Feasible route to high-temperature ambient-pressure hydride superconductivity
A key challenge in materials discovery is to find high-temperature superconductors. Hydrogen and hydride materials have long been considered promising materials displaying conventional phonon-mediated superconductivity. However, the high pressures required to stabilize these materials have restricted their application. Here, we present results from high-throughput computation, considering a wide range of high-symmetry ternary hydrides from across the periodic table at ambient pressure. This lar…

Recurrence and Embeddings in Planar Wind-Tree Models
We study periodic infinite billiards in the plane. We show that for rational models, some particular obstacles can be added periodically, so that the billiard flow in the resulting table is recurrent in almost every direction.

HEX: High-pressure Elemental Xstals, a complete Database
This paper introduces the HEX (High-pressure Elemental Xstals) database, a complete database of the ground-state crystal structures of the first 57 elements of the periodic table, from H to La, at 0, 100, 200 and 300 GPa. HEX aims to provide a unified reference for high-pressure research, by compiling all available experimental information on elements at high pressure, and complementing it with the results of accurate evolutionary crystal structure prediction runs based on Density Functional Th…
