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.

Systematic Search For Evidence of Tetrahedral and Octahedral Symmetries in Subatomic Physics: Follow-up of the First Identification Case in 152Sm [PDF]

open access: yesEPJ Web of Conferences, 2019
In a recent article [1] group-theory representation-methods have been combined with the realistic mean-field calculation results to elaborate new, specifically designed methods of experimental identification of the tetrahedral/octahedral symmetries in ...

Not Only Hydrogen Bonds: Other Noncovalent Interactions

open access: yesCrystals, 2020
In this review, we provide a consistent description of noncovalent interactions, covering most groups of the Periodic Table. Different types of bonds are discussed using their trivial names. Moreover, the new name "Spodium bonds" is proposed for group 12

Order From Confusion: International Chemical Standardization and the Elements, 1947-1990

open access: yesSubstantia, 2019
The International Union of Pure and Applied Chemistry (IUPAC) is the international standards making body for chemistry whose goal is to create a standardized common language for the global chemistry community.

Particular Symmetries: Group Theory of the Periodic System

open access: yesSubstantia, 2020
To this day, a hundred and fifty years after Mendeleev's discovery, the overal structure of the periodic system remains unaccounted for in quantum-mechanical terms.

How do lizard niches conserve, diverge or converge? Further exploration of saurian evolutionary ecology

open access: yesBMC Ecology and Evolution, 2021
Background Environmental conditions on Earth are repeated in non-random patterns that often coincide with species from different regions and time periods having consistent combinations of morphological, physiological and behavioral traits. Observation of

Zeeman slowing of a group-III atom

open access: yesPhysical Review Research, 2022
We realize a Zeeman slower of an atom in main group III of the Periodic Table, otherwise known as the “triel elements.” Despite the fact that our atom of choice (namely indium) does not have a ground state cycling transition suitable for laser cooling ...

Periodic table for Floquet topological insulators [PDF]

open access: yes, 2016
Periodically driven systems have recently been shown to host topological phases that are inherently dynamical in character, opening up a new arena in which to explore topological physics.

Energy of Substitution of Anions and Cations in Zinc and Cadmium Telluride

open access: yesФізика і хімія твердого тіла, 2017
Energy substitution of cations and anions in ZnTe i CdTe by atoms from first and seventh group of the periodic table were calculated using the method of bonding orbitals. Based on the results conclusions about the most likely types of defects by doping.

Tight-binding bond parameters for dimers across the periodic table from density-functional theory [PDF]

open access: yes, 2019
We obtain parameters for non-orthogonal and orthogonal TB models from two-atomic molecules for all combinations of elements of period 1 to 6 and group 3 to 18 of the periodic table.
