Visualizing surface formation of semi-regular polyhedra of Archimedes

open access: yesStructural Mechanics of Engineering Constructions and Buildings, 2020
The most common method of forming semi-control polyhedra consists in cutting off angles and ribs of regular polyhedra by planes. The aim of the work - to consider the automated formation of a number of surfaces of semi-regular Archimedean polyhedra based

Economical Models for Electron Densities

open access: yesThe Journal of Physical Chemistry A, 2023
We discuss a new theoretical framework for modeling molecular electron densities. Our approach decomposes the total density into contributions from basis function products and then approximates each product using constrained least-squares approximation in a tailored local basis of functions with adjustable non-linear parameters.

The role of potassium orbitals in the metallic behavior of K3picene [PDF]

open access: yes, 2014
Detailed electronic structure calculations of picene clusters doped by potassium modeling the crystalline K3picene structure show that while two electrons are completely transferred from potassium atoms to the LUMO of pristine picene, the third one ...
