They are not truly spherical An icosahedral shape is the most efficient way of creating a hardy structure from multiple copies of a single proteinThis virus structure is a conventional icosahedral or helical structure that is surrounded by a lipid bilayer membrane, meaning the virus is encased or enveloped The envelope of the virus is formed when the virus is exiting the cell via budding, and the infectivity of these viruses is mostly dependent on the envelopeThe unusual bonding of the icosahedral boronrich structures gives rise to useful properties that are exploited for several important applications Structure The basic structure of icosahedral boronrich solids is a rhombohedron unit cell with 12atom boron structures at each of its eight vertices These 12atom groups make up an icosahedron, with one boron atom at
