ChromaFlair 1
ChromaFlair is a pigment used in paint systems, primarily for automobiles. When the paint is applied, it changes color depending on the light source and viewing angle. It was created at JDS Uniphase and is used by DuPont and PPG. Names The paint system (and competing versions made by other companies) are known by a wide variety of proprietary names, including ''ChromaLusion'', ''ChromaPremier'', ''ColourShift'', ''Exclusive Line'', ''Extreme Colors'', ''Harlequin Color'', ''IllusionColor'', ''Maziora'', ''MultiTones'', ''MystiChrome'', ''Ch(K)ameleon'', ''Interference Fireglow'' and ''Paradis Spectrashine''. Effect The ChromaFlair effect is achieved by interfering with the reflection and refraction of light from the painted object's surface. The paint contains tiny synthetic flakes about one micrometer thick. The flakes are constructed of aluminium coated with glass-like magnesium fluoride embedded in semi-translucent chromium. The aluminium and chrome give the paint a vibrant ...

Oil Slick
An oil spill is the release of a liquid petroleum hydrocarbon into the environment, especially the marine ecosystem, due to human activity, and is a form of pollution. The term is usually given to marine oil spills, where oil is released into the ocean or coastal waters, but spills may also occur on land. Oil spills may be due to releases of crude oil from tankers, offshore platforms, drilling rigs and wells, as well as spills of refined petroleum products (such as gasoline, diesel) and their by-products, heavier fuels used by large ships such as bunker fuel, or the spill of any oily refuse or waste oil. Oil spills penetrate into the structure of the plumage of birds and the fur of mammals, reducing its insulating ability, and making them more vulnerable to temperature fluctuations and much less buoyant in the water. Cleanup and recovery from an oil spill is difficult and depends upon many factors, including the type of oil spilled, the temperature of the water (affecting evapor ...

Kinechromatic Art
Kinechromatic art is a form of art in which the image, particularly in reference to the colour perceived by the viewer, changes due to some form of movement. The term "kinechromatic" was coined in 1951 by Mario Pedrosa in an article in ''Tribuna da Imprensa'' to refer to the work of Brazilian artist, Abraham Palatnik. Palatnik initially created electro-mechanical devices, based on the kaleidoscopic principle, which projected a constantly changing pattern of coloured light on a screen. Later devices exposed coloured moving parts of the machinery. In all cases, the shape and colour observed were changed by the devices for a stationary observer. Frank Popper, the eminent art historian, among others, commented on Palatnik's "luminous mobiles" and their aesthetic of motion.Frederico Morais, ''Abraham Palatnik : A Pioneer of Technological Art''Leonardo on-line More recently, the term has been applied to the work of Ian Nunn, a Canadian computer scientist and artist who has done extensive ...

Iridescence
Iridescence (also known as goniochromism) is the phenomenon of certain surfaces that appear to gradually change color as the angle of view or the angle of illumination changes. Examples of iridescence include soap bubbles, feathers, butterfly wings and seashell nacre, and minerals such as opal. It is a kind of structural coloration that is due to wave interference of light in microstructures or thin films. Pearlescence is a related effect where some or most of the reflected light is white. The term pearlescent is used to describe certain paint finishes, usually in the automotive industry, which actually produce iridescent effects. Etymology The word ''iridescence'' is derived in part from the Greek word ἶρις ''îris'' ( gen. ἴριδος ''íridos''), meaning ''rainbow'', and is combined with the Latin suffix ''-escent'', meaning "having a tendency toward". Iris in turn derives from the goddess Iris of Greek mythology, who is the personification of the rainbow and ac ...

Alumina Effect Pigment
An alumina effect pigment is a pearlescent pigment based on alumina ( aluminium oxide). It is used for decorative purposes on paints and plastics, giving them a matte, metal-like appearance. Production process In the first step of the production process, Al2O3 ( Aluminium oxide) flakes with a very smooth surface are formed. The flakes are produced using a crystal growth process. They are formed in the corundum structure (α-Al2O3). The desired flake shape is achieved by controlled crystal growth in the axial and equatorial directions. The color purity and transparency of the effect pigments obtained by coating the Al2O3 flakes with metal oxides can be attributed to the synthesis procedure yielding single-crystalline thin flakes The coating of the alumina platelets with high-refractive metal oxides, such as with titanium dioxide and iron(III) oxide leads to strongly reflecting effect pigments. These pigments possess a strong glitter effect. The coating process is analogous to ...

Injection Molding
Injection moulding (U.S. spelling: injection molding) is a manufacturing process for producing parts by injecting molten material into a mould, or mold. Injection moulding can be performed with a host of materials mainly including metals (for which the process is called die-casting), glasses, elastomers, confections, and most commonly thermoplastic and thermosetting polymers. Material for the part is fed into a heated barrel, mixed (using a helical screw), and injected into a mould cavity, where it cools and hardens to the configuration of the cavity. After a product is designed, usually by an industrial designer or an engineer, moulds are made by a mould-maker (or toolmaker) from metal, usually either steel or aluminium, and precision-machined to form the features of the desired part. Injection moulding is widely used for manufacturing a variety of parts, from the smallest components to entire body panels of cars. Advances in 3D printing technology, using photopolymers that ...

Resin
In polymer chemistry and materials science, resin is a solid or highly viscous substance of plant or synthetic origin that is typically convertible into polymers. Resins are usually mixtures of organic compounds. This article focuses on naturally occurring resins. Plants secrete resins for their protective benefits in response to injury. The resin protects the plant from insects and pathogens. Resins confound a wide range of herbivores, insects, and pathogens, while the volatile phenolic compounds may attract benefactors such as parasitoids or predators of the herbivores that attack the plant. Composition Most plant resins are composed of terpenes. Specific components are alpha-pinene, beta-pinene, delta-3 carene, and sabinene, the monocyclic terpenes limonene and terpinolene, and smaller amounts of the tricyclic sesquiterpenes, longifolene, caryophyllene, and delta-cadinene. Some resins also contain a high proportion of resin acids. Rosins on the other hand are less ...

Artificial Leather
Artificial leather, also called synthetic leather, is a material intended to substitute for leather in upholstery, clothing, footwear, and other uses where a leather-like finish is desired but the actual material is cost prohibitive or unsuitable. Artificial leather is known under many names, including ''leatherette'', ''imitation leather'', ''faux leather'', ''vegan leather'', ''PU leather'', and ''pleather''. Manufacture Many different methods for the manufacture of imitation leathers have been developed. A current method is to use an embossed release paper known as ''casting paper'' as a form for the surface finish, often mimicking the texture of top-grain leather. This embossed release paper holds the final texture in negative. For the manufacture, the release paper is coated with several layers of plastic e.g. pvc or polyurethane, possibly including a surface finish, a colour layer, a foam layer, an adhesive, a fabric layer, a reverse finish. Depending on the spec ...

Case Mod
Case modification, commonly referred to as case modding, is the modification of a computer case or a video game console chassis. Modifying a computer case in any non-standard way is considered a case mod. Modding is done, particularly by hardware enthusiasts, to show off a computer's apparent power by showing off the internal hardware, and also to make it look aesthetically pleasing to the owner. Cases may also be modified to improve a computer's performance; this is usually associated with cooling and involves changes to components as well as the case. History When personal computers first became available to the public, the majority were produced in simple, beige-colored cases. This design is sometimes referred to be as a ''beige box''. Although this met the purpose of containing the components of the personal computer, many users considered their computers as "tacky" or "dull", and some began modifying their existing chassis, or building their own from scratch. One of the ori ...

Electric Guitar
An electric guitar is a guitar that requires external amplification in order to be heard at typical performance volumes, unlike a standard acoustic guitar (however combinations of the two - a semi-acoustic guitar and an electric acoustic guitar exist). It uses one or more pickups to convert the vibration of its strings into electrical signals, which ultimately are reproduced as sound by loudspeakers. The sound is sometimes shaped or electronically altered to achieve different timbres or tonal qualities on the amplifier settings or the knobs on the guitar from that of an acoustic guitar. Often, this is done through the use of effects such as reverb, distortion and "overdrive"; the latter is considered to be a key element of electric blues guitar music and jazz and rock guitar playing. Invented in 1932, the electric guitar was adopted by jazz guitar players, who wanted to play single-note guitar solos in large big band ensembles. Early proponents of the electric guitar on ...

Motor Vehicles
A motor vehicle, also known as motorized vehicle or automotive vehicle, is a self-propelled land vehicle, commonly wheeled, that does not operate on Track (rail transport), rails (such as trains or trams) and is used for the transportation of people or cargo. The vehicle propulsion is provided by an engine or motor, usually an internal combustion engine or an electric motor, or some combination of the two, such as hybrid electric vehicles and plug-in hybrids. For legal purpose, motor vehicles are often identified within a number of vehicle classes including cars, buses, motorcycles, off-road vehicles, light trucks and regular trucks. These classifications vary according to the legal codes of each country. International Organization for Standardization, ISO 3833:1977 is the standard for road vehicle types, terms and definitions. Generally, to avoid requiring people with disabilities from having to possess an operator's license to use one, or requiring tags and insurance, powered ...

United States One Hundred-dollar Bill
The United States one-hundred-dollar bill ($100) is a denomination of United States currency. The first United States Note with this value was issued in 1862 and the Federal Reserve Note version was launched in 1914, alongside other denominations. Statesman, inventor, diplomat, and American founding father Benjamin Franklin has been featured on the obverse of the bill since 1914. On the reverse of the banknote is an image of Independence Hall in Philadelphia, which has been used since 1928. The bill is the largest denomination that has been printed and circulated since July 13, 1969, when the larger denominations of , , , and were retired. As of December 2018, the average life of a bill in circulation is 22.9 years before it is replaced due to wear. The bills are also commonly referred to as "Bens", "Benjamins", or "Franklins", in reference to the use of Benjamin Franklin's portrait by the French painter Joseph Duplessis on the denomination, as "C-Notes" or "Century Notes", ...
