Mg fills the entire void of the eight faces and is the 38 body structure.Crystal morphology:Usually dense, blocky, leaf like, fibrous. Characterized by fibrous aggregates called serpentine asbestos.4 serpentinePhysical proper...
The crystal structure of a new natural (Na,Mn,Ti)-phyllosilicate, (Na0.80K0.45) xNa5Mn2+(Ti0.75Nb0.25)[Si10O24(OH)](O,OH)(OH) 2·4H2O, is determined (Syntex P1 automated diffractometer, 1881 reflections, a heavy-atom method, anisotropic approximation, and R=6.6%). The unit-cell pa...
structure consisting of magnesium (Mg) and silicon (Si) atoms in an octahedral coordination and is sim- ilar to the crystal structure of δ -AlOOH17,18 where aluminum (Al) atoms occur in octahedral sites. Owing to the possibility of the configurational disorder of the Mg and Si atoms ...

Shown above is a specimen of lizardite serpentine from Wayne County, New York. The piece has no visible internal structure or characteristic external shape.Oolitic Oolitic minerals occur in crystalline aggregates that are rounded and less than about four millimeters in size. Oolites form by chemical...
To clarify the structural basis for inhibition of both nuclear entry and DNA binding of NF-κB by IκBα, we have determined the crystal structure of a murine NF-κB p50/p65 heterodimer in complex with human IκBα. The crystal structure illustrates how IκBα/NF-κB interactions promote cy...
Various types of shell have been used as gems for centuries. One of these types include those made up of pearly layers: mother of pearl, abalone and New Zealand paua. Uses: strengthens the structure of the body and the functions of the heart chakra. Both pearl and abalone shell hold the...
