RuBisCO Ribulose-1,5-bisphosphate carboxylase/oxygenase, commonly known by the abbreviations RuBisCO, RuBPCase, or RuBPco, is an enzyme involved in the first major step of carbon fixation, a process by which atmospheric carbon dioxide is converted by plants and other photosynthetic organisms to energy-rich molecules such as glucose. In chemical terms, it catalyzes the carboxylation of ribulose-1,5-bisphosphate. It is probably the most abundant enzyme on Earth.

Phosphorescence Phosphorescence is a type of photoluminescence related to fluorescence. Unlike fluorescence, phosphorescent material does not immediately re-emit the radiation it absorbs. The slower time scales of the re-emission are associated with forbidden energy state transitions in quantum mechanics.

Dyeing Dyeing is the process of adding color to textile products like fibers, yarns, and fabrics. Dyeing is normally done in a special solution containing dyes and particular chemical material. After dyeing, dye molecules have uncut chemical bond with fiber molecules. The temperature and time controlling are two key factors in dyeing. There are mainly two classes of dye, natural and man-made.

- Gentian Violet. Gentian violet is a water soluble dye (coloring substance) used primarily in medicine to stain bacteria, but also in other histological procedures. It is not derived from gentians, but got its name since it is pink-violet like some gentians in the genera of Centaurium, Gentiana, and Gentianella.

Indigo dye Indigo dye is an organic compound with a distinctive blue color (see indigo). Historically, indigo was a natural dye extracted from plants, and this process was important economically because blue dyes were once rare. A large percentage of indigo dye produced today – several thousand tons each year – is synthetic.ndigo dye is an organic compound with a distinctive blue color (see indigo).

Natural dye Natural dyes are dyes or colorants derived from plants, invertebrates, or minerals. The majority of natural dyes are vegetable dyes from plant sources—roots, berries, bark, leaves, and wood—and other organic sources such as fungi and lichens. Archaeologists have found evidence of textile dyeing dating back to the Neolithic period.

Photosynthesis Pigments are molecules with their own characteristic absorption spectra in response to light. The perceived color of the pigment depends upon the wavelengths of light that are not absorbed.A chromophore is the moiety within the pigment molecule that is responsible for the molecule's color. The chromophore possesses two orbitals whose difference in energy falls within the light spectrum.bsorption Spectrum: results from the ability of pigments to absorb incident electromagnetic radiation. Like the action spectrum, the parameter of interest (light absorbed) is plotted as a function of the wavelength of the radiation.

Diagnosis Prussian blue (Radiogardase). This type of dye binds to particles of radioactive elements known as cesium and thallium. The radioactive particles are then excreted in feces. This treatment speeds up the elimination of the radioactive particles and reduces the amount of radiation cells may absorb. Diethylenetriamine pentaacetic acid (DTPA).

Basic Dye/Cationic Dyes | Properties of Basic Dyes | Dyeing of Acrylic with Basic Dyes Basic dyes are called cationic dyes because the chromophore in basic dye molecules contains a positive charge. The basic dyes react on the basic side of the isoelectric points. Basic dyes are salts, usually chlorides, in which the dyestuff is the basic or positive radical.asic dyes are called cationic dyes because the chromophore in basic dye molecules contains a positive charge.

- Penalty for Failure to File a Tax Return by the Due Date. The late filing penalty applies to any portion of tax that is unpaid as of the payment due date and the tax return is filed after the filing due date.urrently, the IRS interest rate for underpayments of tax is 3% per year. The interest is calculated for each day your balance due is not paid in full. Interest is assessed on the unpaid amount of tax plus any late filing or late payment penalties.

Dye Sulfur dyes are inexpensive dyes used to dye cotton with dark colors. Dyeing is effected by heating the fabric in a solution of an organic compound, typically a nitrophenol derivative, and sulfide or polysulfide. The organic compound reacts with the sulfide source to form dark colors that adhere to the fabric.

- Pigments are colorful compounds. Pigments are chemical compounds which reflect only certain wavelengths of visible light. This makes them appear colorful. Flowers, corals, and even animal skin contain pigments which give them their colors. More important than their reflection of light is the ability of pigments to absorb certain wavelengths. Because they interact with light to absorb only certain wavelengths, pigments are useful to plants and other autotrophs --organisms which make their own food using photosynthesis. In plants, algae, and cyanobacteria, pigments are the means by which the energy of sunlight is captured for photosynthesis.

Dyes Hair dyes are of two types: permanent and semipermanent. Permanent dyeing is achieved with a synthetic dye, applied with hydrogen peroxide that first bleaches the natural pigment melanin. Semipermanent dyes are generally made with vegetable extracts, such as henna, that coat rather than penetrate the hair shaft.olor is applied by the process of dyeing, which in its simplest form involves the immersion of a fabric in a solution of a dyestuff in water. Patterned effects are obtained by selectively applying dyes to fabric, for example by roller printing.
