Sentences with word «icosahedral»

Objects with icosahedral symmetry occur in nature only at microscopic scales, including quasicrystals, many viruses and some beautiful protozoa in the radiolarian family

The researchers were able to show how five different kinds of proteins formed three different kinds of shapes: hexagons, pentagons and a stacked pair of hexagons, which assembled together into a 20 - sided icosahedral shell.

A negatively - charged C60 molecular ion can undergo a Jahn - Teller distortion by reshaping its molecular structure away from perfect icosahedral symmetry.

To confirm the presence of virus in diseased tissues, we examined lung tissue from affected monkeys by transmission electron microscopy, revealing abundant icosahedral particles characteristic of adenovirus filling the alveoli (Fig. 1D - 4).

The fullerene molecules consist of 60 carbon atoms arranged in a truncated icosahedral shape (a soccer ball) and pack in a regular cubic - close - packed array in three dimensions.

The head for example is an icosahedral with each of the proteins represented (gp24, gp23, Hoc, Soc) albeit in shiny metals.

The structure of Zika virus is similar to other known flavivirus structures, except for the ~ 10 amino acids that surround the Asn154 glycosylation site in each of the 180 envelope glycoproteins that make up the icosahedral shell.

This image explores the structure of the icosahedral group through a particular presentation by two generators.

This work is part of a series of visual meditations on the structure of the alternating group on 5 elements, also known as the icosahedral group.

The lab made tiny structures — icosahedral, like a 20 - sided die — with two halves that clamp together around a payload of molecules to form a capsule.

Correct assembly of the icosahedral core of HBV is required for replication; reverse transcription of the RNA pre-genome takes place within the completed capsid, the protein shell of the core.
