Densest local packing diversity. II. Application to three dimensions

, 2010
The densest local packings of N three-dimensional identical nonoverlapping spheres within a radius Rmin(N) of a fixed central sphere of the same size are obtained for selected values of N up to N = 1054. In the predecessor to this paper [A.B.

Unexpected {Pu60} Cage Cluster Units in New Plutonium(VI) Oxido‐Hydroxides

Angewandte Chemie Novit, Volume 2, Issue 1, March 2026.
Plutonium(VI) hydrolysis in strongly alkaline NaCl‐NaOH solutions yields needle‐ and platelet‐like crystals. They are built from unprecedented spherical [(PuO2)60O20(OH)120]40− cages that adopt a truncated dodecahedral (Archimedean) topology. Each {Pu60} cage contains 20 identical trimeric subunits, which self‐assemble from Pu(VI) solution trimers ...

The Electronically Confined Space Analogy Elucidates How Second‐Row Triatomic 18‐Valence‐Electron Molecules Shape Life and Light

ChemistryOpen, Volume 15, Issue 3, March 2026.
The Electronically Confined Space Analogy explains ozone's unique UV absorption by linking bent 18‐valence‐electron structures to enhanced stability and photochemical activity, offering a molecular‐level rationale for its dominance as Earth's stratospheric UV filter.

Isolation and characterization of bacteriophages of rumen bacterium Prevotella bryantii TC1-1

Acta Agriculturae Slovenica, 2000
Sampling, inoculation and extraction procedures were elaborated for the isolation of bacteriophages from cattle rumen fluid. Several strains from four different species of rumen bacterial genus Prevotella were used as indicator organisms as well as ...

Effects of scars on crystalline shell stability under external pressure

, 2014
We study how the stability of spherical crystalline shells under external pressure is influenced by the defect structure. In particular, we compare stability for shells with a minimal set of topologically-required defects to shells with extended defect ...

The Microlayer Framework: Extension to Aggregates With Non‐Uniform Shapes

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 1, March 2026.
ABSTRACT The microlayer framework is a novel, powerful method for the numerical simulation of heterogeneous materials, such as aggregate‐matrix composites across different scales. While the framework has previously only been applied to geometrically isotropic aggregates, its mathematical formulation also enables the development of material models for ...

Octahedral small virus-like particles of dengue virus type 2

Journal of Virology
Flavivirus envelope (E) and precursor M (prM) proteins, when ectopically expressed, assemble into empty, virus-like particles (VLPs). Cleavage of prM to M and loss of the pr fragment converts the VLPs from immature to mature particles, mimicking a ...

Icosahedral symmetry and the quintic equation

Computers & Mathematics with Applications, 1992
It was known in the 19th century that a quintic equation could be solved in terms of elliptic functions. Starting from consideration of the symmetry group of the icosahedron, the authors develop an algorithm, that involves theta functions, and avoids ambiguities and errors that were in earlier work.

Medical Gas Plasma Inactivates Adenoviruses via Capsid Oxidation

Small, Volume 22, Issue 15, 12 March 2026.
Oxidative modification of three adenoviral capsid proteins after gas plasma treatment. Schematic representation of the viral infection process, starting with the initial attachment of the virus via its fiber protein binding to the cellular receptors (CAR and/or CD46). In the secondary attachment step, the penton base binds to integrin structures on the
