DNA duplex cage structures with icosahedral symmetry

open access: yesTheoretical Computer Science, 2009
A construction method for duplex cage structures with icosahedral sym- metry made out of single-stranded DNA molecules is presented and applied to an icosidodecahedral cage. It is shown via a mixture of analytic and computer techniques that there exist realisations of this graph in terms of two circular DNA molecules.

Soft modes near the buckling transition of icosahedral shells

open access: yes, 2007
Icosahedral shells undergo a buckling transition as the ratio of Young's modulus to bending stiffness increases. Strong bending stiffness favors smooth, nearly spherical shapes, while weak bending stiffness leads to a sharply faceted icosahedral shape ...

Intercluster Bonds: On the Making of Extended Materials From Superatoms

open access: yesAggregate, Volume 7, Issue 3, March 2026.
The development of superatomic clusters as analogs to prototypical classical molecules represents a significant advancement in understanding chemical bonding in cluster‐based materials. This perspective explores advances in bonding concepts for understanding superatomic chemistry by applying classical bonding principles to cluster‐based materials ...

Structural Capsidomics of Single-Stranded DNA Viruses

open access: yesViruses
Single-stranded DNA (ssDNA) viruses are a diverse group of pathogens with broad host range, including bacteria, archaea, protists, fungi, plants, invertebrates, and vertebrates. Their small compact genomes have evolved to encode multiple proteins.

Encapsulation of a polymer by an icosahedral virus

open access: yes, 2010
The coat proteins of many viruses spontaneously form icosahedral capsids around nucleic acids or other polymers. Elucidating the role of the packaged polymer in capsid formation could promote biomedical efforts to block viral replication and enable use ...

Chiral Metal Nanoclusters: Structure, Synthesis, and Optoelectronic Applications

open access: yesAggregate, Volume 7, Issue 3, March 2026.
Chiral metal nanoclusters (NCs) possess atomically precise structures and unique chiroptical properties. This review systematically summarizes chiral origins, synthetic strategies, and optoelectronic applications of chiral metal NCs, outlining challenges and future perspectives in this edge‐cutting area.

Tailoring the Electron Affinity of Au13 Superhalogen via Ligand Design

open access: yesAggregate, Volume 7, Issue 3, March 2026.
The electron affinities (EAs) of thiophenolate (RS)‐protected gold clusters Au25(SR)18 were determined by gas‐phase photoelectron spectroscopy of the corresponding anions [Au25(SR)18]−. Correlation analysis revealed a linear relationship between the EA and the dipole moment of the RS ligands, which can be explained by the concept of surface potential ...

The microscopic pathway to crystallization in supercooled liquids

open access: yes, 2012
Despite its fundamental and technological importance, a microscopic understanding of the crystallization process is still elusive. By computer simulations of the hard-sphere model we reveal the mechanism by which thermal fluctuations drive the transition

Accelerating Crystal Structure Prediction Using Data‐Derived Potentials: High‐Pressure Binary Hydrides

open access: yesAnnalen der Physik, Volume 538, Issue 3, March 2026.
Bespoke machine‐learning potentials significantly accelerate the discovery of binary hydrides under extreme pressure. An active learning pipeline identifies novel structural motifs, including supermolecular H25Cs and neutral icosahedral clusters in noble gas systems.

In situ structures of the segmented genome and RNA polymerase complex inside a dsRNA virus. [PDF]

open access: yes, 2015
Viruses in the Reoviridae, like the triple-shelled human rotavirus and the single-shelled insect cytoplasmic polyhedrosis virus (CPV), all package a genome of segmented double-stranded RNAs (dsRNAs) inside the viral capsid and carry out endogenous ...
