61Glossary of geology terms — Here is a glossary of Geological terms.A*Abyssal plain Flat or very gently sloping areas of the deep ocean basin floor. *Absolute dating the process of determining a specific date (in years or some other unit of time) for an archaeological,… …
62Chemical vapor deposition — DC plasma (violet) enhances the growth of carbon nanotubes in this laboratory scale PECVD apparatus. Chemical vapor deposition (CVD) is a chemical process used to produce high purity, high performance solid materials. The process is often used in …
63Optical amplifier — An optical amplifier is a device that amplifies an optical signal directly, without the need to first convert it to an electrical signal. An optical amplifier may be thought of as a laser without an optical cavity, or one in which feedback from… …
64Concrete sealers — are coatings applied to concrete to protect it from corrosion. They either block the pores in the concrete to reduce absorption of water and salts or form an impermeable layer which prevents such materials from passing.[1] Extensive research from …
65Zeolite — Zeolites (Greek, zein , to boil ; lithos , a stone ) are hydrated aluminosilicate minerals and have a micro porous structure. The term was originally coined in the 18th century by a Swedish mineralogist named Axel Fredrik Cronstedt who observed,… …
66Glass transition — The liquid glass transition (or glass transition for short) is the reversible transition in amorphous materials (or in amorphous regions within semicrystalline materials) from a hard and relatively brittle state into a molten or rubber like state …
67Clay — For other uses, see Clay (disambiguation). The Gay Head cliffs in Martha s Vineyard consist almost entirely of clay. Clay is a general term including many combinations of one or more clay minerals with traces of metal oxides and organic… …

69Dispersion (optics) — This article is about dispersion of waves in optics. For other forms of dispersion, see Dispersion (disambiguation). In a prism, material dispersion (a wavelength dependent refractive index) causes different colors to refract at different angles …
70List of fire-retardant materials — A fire retardant material is one that is designed to resist burning and withstand heat. It is used in the bunker gear worn by firefighters to protect them from the flames in a burning building. Most auto racing drivers also wear fire retardant… …
