High Quality Content by WIKIPEDIA articles! Cathodoluminescence is an optical and electrical phenomenon whereby a beam of electrons is generated by an electron gun (e.g., cathode ray tube) and then impacts on a luminescent material such as a phosphor, causing the material to emit visible light. The most common example is the screen of a television. In geology, mineralogy and materials science a scanning electron microscope with specialized optical detectors, or an optical cathodoluminescence microscope, is used to examine internal structures of semiconductors, rocks, ceramics, glass, etc. in order to get information on the composition, growth and quality of the material.
High Quality Content by WIKIPEDIA articles! Cationic polymerization is a type of chain growth polymerization in which a cationic initiator transfers charge to a monomer which becomes reactive. This reactive monomer goes on to react similarly with other monomers to form a polymer. Poly(isobutylene) used in inner tubes is the only polymer being commercially produced via cationic polymerization. The types of monomers necessary for cationic polymerization are limited to olefins with electron-donating substituents and heterocycles. Similar to anionic polymerization reactions, cationic polymerization reactions are very sensitive to the type of solvent used. Specifically, the ability of a solvent to form free ions will dictate the reactivity of...

A cat’s whisker detector (sometimes called a crystal detector) is an antique electronic component consisting of a thin wire that lightly touches a crystal of semiconducting mineral (usually galena) to make a crude point-contact rectifier. Developed by early radio researchers Jagadish Chandra Bose, G. W. Pickard and others, this device was used as the detector in early crystal radios, from about 1906 through the Second World War. It gave this type of radio receiver its name. It was the first type of semiconductor diode, and in fact the first semiconductor electronic device. The term cat`s whisker was also sometimes used to describe the crystal receiver itself. Cat`s whisker detectors are...

The oldest form of caulking is used to make the seams in wooden boats or ships watertight, by driving fibrous materials into the wedge-shaped seams between planks. A related process was formerly employed to join sections of cast iron sewerage pipe.

Cave Run Lake, located south of Morehead, Kentucky, USA along Kentucky Route 801, is an 8,270-acre (33 km2), reservoir built by the U.S. Army Corps of Engineers. The 148 ft (45 m), half-mile (800 m) dam (and outlet works) construction began in 1965 and was completed in 1973. Cave Run Lake is in the northern part of the Daniel Boone National Forest. Cave Run Lake provides flood protection to the lower Licking River valley, supplies water to the area`s communities, improves the Licking River`s water flow conditions, and offers a habitat for various species of fish and wildlife. It is in Rowan, Morgan, Menifee, and Bath counties.

The Cedar Mountain Formation is the name given to distinctive sedimentary rocks in eastern Utah that occur between the underlying Morrison Formation and overlying Naturita Formation (sometimes incorrectly called the Dakota Formation). It is composed of non-marine sediments, that is, sediments deposited in rivers, lakes and on flood plains. Based on various fossils and radiometric dates, the Cedar Mountain Formation was deposited during the last half of the Early Cretaceous, about 127 - 98 million years ago (mya).

Building insulation is low-thermal-conductivity material used to separate the internal climate and sounds of a building from external climate and sounds. Cellulose insulation is plant fiber used in wall and roof cavities to separate the inside and outside of the building thermally and acoustically.

Cemented carbide, also called tungsten carbide, hardmetal, or widia, is a hard material used in machining tough materials such as carbon steel or stainless steel, as well as in situations where other tools would wear away, such as high-quantity production runs. Most of the time, carbide will leave a better finish on the part, and allow faster machining. Carbide tools can also withstand higher temperatures than standard high speed steel tools.

The centrifugal mico-fluidic biochip or centrifugal micro-fluidic biodisk is a type of lab-on-a-chip technology that can be used to integrate processes such as separating, mixing, reaction and detecting molecules of nano-size in a single piece of platform, including a compact disk or DVD. This type of micro-fluidic biochip is based upon the principle of microfluidics; to take advantage of noninertial pumping for lab-on-a-chip devices using noninertial valves and switches under centrifugal force and Coriolis effect to distribute fluids about the disks.
