Straw

== Description ==
A general name for stalks from cereal grain plants, such as wheat, barley, rye, oat, and rice. Since ancient times, straw fibers have been woven or braided to form hats, bags, shoes, mats, and baskets. Straw was also used for papermaking in ancient China. It was the primary fiber used for paper in Europe and North America from the 18th century until the 1920s when it was replaced by wood pulp. Straw pulp is still used for strawboard, printing paper, wallpaper, and inexpensive wrapping papers.
== Synonyms and Related Terms ==
barley straw; oat straw; rice straw; rye straw; wheat straw; bagasse; espiga (Esp.)
== Physical and Chemical Properties ==
Stains pink with aniline sulfate. Fibers are 1 - 1.5 mm long
Paper fiber type: non-woody, grass. Using transmitted light microscopy, pulp is identified by the presence of variable-sized barrel-shaped parenchyma cells. Serrated epidermal cells are abundant. Unwound spiral thickenings are also present. Fibers are short and appear similar to hardwood fibers. It is difficult to distinguish cereal straws from each other (wheat, oat, rye and barely). Appearance with Graff "C" stain: fibers stain dark, other vessels may have variable colors. Average dimensions of fibers: length 1.4 mm, width 15 μm. Common pulping method: various, typically soda or sulfate.

== Analytical instrumentation and procedures ==
HPLC-DAD-MS analysis was performed with an Agilent 1100 liquid chromatography system consisting of an automatic injector, a gradient pump, a HP series 1100 DAD, and an Agilent series 1100 VL on-line atmospheric pressure ionization electrospray ionization mass spectrometer. Separations were done on a Vydac 214TP52 analytical column (2.1 mm diameterX250 mm; 5-ím particle size). The column was eluted at a flow rate of 0.2 mL/min with a tertiary gradient of water (A),acetonitrile (B), and 1% (v/v) aqueous formic acid (C) with the following elution program: 0 min, 90% A, 5% B, 5% C; 0-55 min, a linear gradient to 35% A, 60% B, 5% C; 55-60 min, a linear gradient elution to 15% A, 80% B, 5% C; 60-62 min, isocratic elution at 15% A, 80% B, 5% C; 62-70 min gradient elution to 90% A, 5% B, 5% C; and reequilibration with the latter solvent for 15 min. The mass spectrometer was run both in the negative and positive ion mode.

Strontium

== Description ==
A soft, yellow metallic element. Strontium occurs in nature as the minerals celestine (sulfate) and strontianite (carbonate). It was discovered in 1790 by Adair Crawford in Scotland and isolated by Davy in 1807. Strontium is primarily mined in England. Freshly cut strontium is silvery, but it quickly tarnishes to a yellow tone in air. Strontium is used in fireworks and railroad flares to produce a bright red color. Some of the radioactive isotopes of strontium are used medicinally and as an ingredients in luminous paint and atomic batteries. Strontium oxide is used in ceramic glazes as a nontoxic replacement for lead.
== Synonyms and Related Terms ==

== Risks ==
* Powder is spontaneously flammable. 
* Explosion risk from hydrogen gas produced with water reactions. 
* Radioactive isotopes are highly toxic.

Strontium chromate

== Description ==
A pale yellow pigment that is also called strontium yellow. Strontium yellow was used in oil paints in the late 19th and early 20th centuries. It has good opacity and stability to light and heat. But because of its high hiding power, strontium chromate was not used in watercolors. Commercially strontium chromate was often mixed with other pigments; a mixture with Prussian blue was sold as green cinnabar and a mixture with barium yellow and zinc yellow was sold under the name lemon yellow or citron yellow. Currently strontium yellow is used in anticorrosive coating and pyrotechnics.

Strontium titanate

== Description ==
Transparent, colorless single crystals of strontium titanate have been grown synthetically since the late 1940s. Strontium titanate is used for imitation diamonds and electronic components. The natural mineral of strontium titanate (tausonite) is muddy brown to gray color and was discovered in 1982. Synthetic strontium shows more fire than diamonds but is similarly isotropic, meaning there is no distracting doubling of facets as seen in synthetic rutile.. However, due to its softness, the facets and polish so not maintain well. The surface may also show residual polishing marks. Their density makes allows loose stones to be easily distinguished from diamonds. Synthetic strontium titanate is transparent and colorless, but may be doped to formed red, yellow,brown or blue.

Structural glass

== Description ==
A general term for a variety of architectural glasses but usually refers to colored opaque glass slabs (Dyson, 1995). About 1900, opaque glass slabs (Sani-Onyx) were first developed as a sanitary alternative to white marble slab table surfaces. Opaque structural glass was composed of silica, borax, feldspar, fluorspar (for opacity), kaolin, cryolite, manganese and inorganic colorants. The sheets were cast then rolled to form a smooth even surface. They were cooled slowly, then fire-polished to produce a smooth satiny finish. Some glass pieces were polished to achieve a high gloss. Opaque glass was available in many colors, but most common were white and black. Structural glass was popularly used in the 1920 to 1940s for exterior cladding on storefronts, service stations, movie theaters and automobile dealerships. It was also used for interior clean surface areas such as hospital operating rooms, hotel lobbies, restaurants, kitchens, and bathrooms.
