Sepiolite

== Description ==
1) A hydrated magnesium silicate clay that is also called meerschaum. Sepiolite is a fine-grain, grayish-white clay that occurs in Asia Minor, Morocco, Spain, New Mexico, and Pennsylvania. The light porous clay can be cut easily when it is wet and will withstand heat well. It is used as a building stone, a filler in soaps, and for making ornamental pipes and cigar holders. It is also sold as a commercial product under the name Sepiolite. Sepiolite has also been used as a poulticing material for cleaning stains from stone and textiles (Heuman and Garland 1987). 
2) (not common) A powder composed of ground cuttlefish bones. Sepiolite, also called sepia powder, is composed of calcium carbonate and calcium phosphate. It is used as a polishing agent.

Shagreen

== Description ==
A leather with a rough, granulated surface. Shagreen was originally made in the near East from donkey, mule, or horse skin. It was artificially grained by pressing small, hard goosefoot seeds (Chenopodium album) into the surface. The skins were trampled then left in the sun to dry. The embedded seeds formed indentations in the dried skins while the seed oils aided in the tanning process. By the late 17th century, the name shagreen was also used for Galuchat leather, tanned skins from sharks and rays, probably because both had a pebbly surface and were often dyed green. Shagreen leather was used for clothing, boots, sword hilts, pistol covers, and book bindings.

Shale

== Description ==
An abundant sedimentary rock consolidated from layers of clay and mud. Shale has very fine grains and a laminated structure that fractures easily along the bedding lines. The stone is soft, smooth, and can feel greasy. Shale is composed of clay (>30%) and silica along with smaller quantities of carbonates, feldspars, iron oxides, fossils, and organic matter (called shale oil). Shale oil, or kerogen, is a sulfurous hydrocarbon that can be refined as a source of fuel. Shale can vary in color from gray, brown, black, green, or red. Shale is used in the manufacture of ceramics, tile, and brick. It is also a source of alumina for portland cement.

Shape memory alloy

== Description ==
A metal alloy that can be deformed then return to its original shape with heat. Shape-memory alloys (SMA) take advantage of phase transformations; liquid to solid or liquid to gas transitions are widely known, but changes can also occur with solid phases when the atoms or molecules that make up a material adopt a different pattern. An SMA has two phases: austenite (symmetrical) and martensite (asymmetrical). The switch between the two phases can be induced by temperature or pressure. The first shape metal alloy discovered in the 1950s by William Buehler at the U.S. Naval Ordinance Laboratory (composed of nickel (55%) and titanium (45%)) was called Nitinol. In Nitinol, the phase change is just above room temperature. One example shows a crumpled spoon spring back to its original shape when placed in a cup of warm water. Less expensive shape memory metals are composed of copper-zinc-aluminum or copper-aluminum-nickel alloys, as well as many others.
== Synonyms and Related Terms ==
shape memory alloy; SMA; memory metal memory alloy; smart metal; muscle wire; Nitionol (Deut.)
==Applications ==
* Construction in earthquake areas to allow yield but no permanent deformations
* Used in reinforced concrete to sense cracks then contract to close them
* Used medicinally for clogged arteries, bone repair, valve actuation and dental braces
==Physical and Chemical Properties==
* High strength along with elasticity
* Bio-compatible
* Lightweight
* Expensive
