These data lead to a structure in which sheets of Cr atoms lie between two sheets of O atoms.

These later sheets could include many individual songs, which would be cut apart and sold individually as " slipsongs.

These sheets are rolled at specific and discrete (" chiral ") angles, and the combination of the rolling angle and radius decides the nanotube properties ; for example, whether the individual nanotube shell is a metal or semiconductor.

These sheets were cut into smaller window panes with nonuniform thickness, typically with the location of the pour centred in one of the panes ( known as " bull's-eyes ") for decorative effect.

These tetrahedra can be polymerized to give the subclasses: orthosilicates ( no polymerization, thus single tetrahedra ), disilicates ( two tetrahedra bonded together ), cyclosilicates ( rings of tetrahedra ), inosilicates ( chains of tetrahedra ), phyllosilicates ( sheets of tetrahedra ), and tectosilicates ( three-dimensional network of tetrahedra ).

These silica tetrahedra are then polymerized to some degree to create various structures, such as one-dimensional chains, two-dimensional sheets, and three-dimensional frameworks.

In addition to the tetrahedra, phyllosilicates have a sheet of octahedra ( elements in six-fold coordination by oxygen ) that balanced out the basic tetrahedra, which have a negative charge ( e. g. < sup > 4 -</ sup >) These tetrahedra ( T ) and octahedra ( O ) sheets are stacked in a variety of combinations to create phyllosilicate groups.

These sheets are chemically inert, dielectric, elastic, flexible, hydrophilic, insulating, lightweight, platy, reflective, refractive, resilient, and range in opacity from transparent to opaque.

These thrust faults carry relatively thin slices of rock ( which are called nappes or thrust sheets, and differ from tectonic plates ) from the core of the shortening orogen out toward the margins, and are intimately associated with folds and the development of metamorphism.

These algae strengthen the reef structure by depositing limestone in sheets over the reef surface.

These sheets are available in various materials such as alumina, zirconia and magnesia.

These would have been made with thin sheets of precious metal over a wooden core.

These deposits include glacial till, sand and gravel and both terminal and recessional moraines left by receding ice sheets at the end of the last ice age.

These membranes are flat sheets that form a continuous barrier around cells.

These sheets are referred to as alclad, and are commonly used by the aircraft industry.
