All-atom molecular dynamics of the HBV capsid reveals insights into biological function and cryo-EM resolution limits

eLife, 2018
The hepatitis B virus capsid represents a promising therapeutic target. Experiments suggest the capsid must be flexible to function; however, capsid structure and dynamics have not been thoroughly characterized in the absence of icosahedral symmetry ...

A Keplerian Ag90 nest of Platonic and Archimedean polyhedra in different symmetry groups

Nature Communications, 2020
Nested polyhedra are compelling but incredibly complex synthetic targets in cluster chemistry. Here, the authors synthesize a Ag90 nanocluster comprising three concentric polyhedra with apparently incompatible octahedral (Oh) and icosahedral (Ih ...

Fusion process of Lennard-Jones clusters: global minima and magic numbers formation [PDF]

, 2003
We present a new theoretical framework for modelling the fusion process of Lennard-Jones (LJ) clusters. Starting from the initial tetrahedral cluster configuration, adding new atoms to the system and absorbing its energy at each step, we find cluster ...

Density Functional Theory for Buckyballs within Symmetrized Icosahedral Basis

Nanomaterials, 2023
We have developed a highly efficient computation method based on density functional theory (DFT) within a set of fully symmetrized basis functions for the C60 buckyball, which possesses the icosahedral (Ih) point-group symmetry with 120 symmetry ...

Magnetic dynamics of hedgehog in icosahedral quasicrystal

Scientific Reports, 2022
Quasicrystals (QCs) possess a unique lattice structure without translational invariance, which is characterized by the rotational symmetry forbidden in periodic crystals such as the 5-fold rotation.

The Double Cover of the Icosahedral Symmetry Group and Quark Mass Textures

, 2011
We investigate the idea that the double cover of the rotational icosahedral symmetry group is the family symmetry group in the quark sector. The icosahedral (A5) group was previously proposed as a viable family symmetry group for the leptons.

DNA Cages with Icosahedral Symmetry in Bionanotechnology [PDF]

, 2009
Blueprints of polyhedral cages with icosahedral symmetry made of circular DNA molecules are provided. The basic rule is that every edge of the cage is met twice in opposite directions by the DNA strand, and vertex junctions are realised by a set of admissible junction types.

A molecular overlayer with the Fibonacci square grid structure

Nature Communications, 2018
Quasicrystals possess long range order but no translational symmetry, and rotational symmetries that are forbidden in periodic crystals. Here, a fullerene overlayer deposited on a surface of an icosahedral intermetallic quasicrystal achieves a Fibonacci ...

Icosahedral (A5) Family Symmetry and the Golden Ratio Prediction for Solar Neutrino Mixing

, 2009
We investigate the possibility of using icosahedral symmetry as a family symmetry group in the lepton sector. The rotational icosahedral group, which is isomorphic to A5, the alternating group of five elements, provides a natural context in which to ...
