- The Laser/Atom Connection. A laser is a device that controls the way that energized atoms release photons. Laser is an acronym for light amplification by stimulated emission of radiation, which describes very succinctly how a laser works. Although there are many types of lasers, all have certain essential features.

What are Chemoreceptors? Like other neurons, these cells are usually designed with customized locks which only fit the keys of specific chemicals, which makes them sensitive only to certain types of chemicals or chemical families. An example of direct chemoreceptors are the cells located on the tongue. When people taste food, it is because these cells respond to the chemicals in the food, sending a signal to the brain to let the brain know about what's happening in the mouth.

- A power morcellator is a surgical device that has been used for gynecological surgical procedures. It was intended to remove tumors, and diseased tissue or organs through minimally invasive surgery. Though it was designed to reduce risk to the patients, its use may also spread cancer cells when tumors are removed.

- Copaxone (glatiramer acetate) is an immunomodulator used to reduce the frequency of relapses in patients with multiple sclerosis (MS). It is not an interferon, but may be grouped with interferon betas Avonex and Betaseron; together the three first-line treatments are sometimes known as the ABC drugs for MS.opaxone (glatiramer acetate) is an immunomodulator used to reduce the frequency of relapses in patients with multiple sclerosis (MS).

- Structures With Bidentate Ligands. Bidentate ligands are Lewis bases that donate two pairs (bi) of electrons to a metal atom. Bidentate ligands are often referred to as chelating ligands (chelate is derived from the Greek word for claw) because they can grab a metal atom in two places.A complex that contains a chelating ligand is called a chelate. Fe = O = C oxalate ion (ox)Oxalate ion is a bidentate ligand even though it contains four O atoms which have lone pairs of electrons. [Fe(C2O4)3]3-In this complex, three oxalate ions are bonded to the Fe atom. The coordination number of 6 results in an octahedral structure.

What are chemoautotrophs? Chemotrophs are organisms that obtain energy by the oxidation of electron donors in their environments. These molecules can be organic (chemoorganotrophs) or inorganic (chemolithotrophs). The chemotroph designation is in contrast to phototrophs, which utilize solar energy.ost are bacteria or archaea that live in hostile environments such as deep sea vents and are the primary producers in such ecosystems. Chemoautotrophs generally fall into several groups: methanogens, halophiles, sulfur oxidizers and reducers, nitrifiers, anammox bacteria, and thermoacidophiles.

- The chelate formed from a mordant dye and a metal is called a lake. This term is derived from lac, a mordant dye obtained from an insect in India, and from which shellac is obtained. Over time the term lac has changed to lake and has come to be the generic term for all dye-mordant complexes.

- An electron transport chain (ETC) is a series of compounds that transfer electrons from electron donors to electron acceptors via redox reactions, and couples this electron transfer with the transfer of protons (H + ions) across a membrane.lectron transport chains are redox reactions that transfer electrons from an electron donor to an electron acceptor. The transfer of electrons is coupled to the translocation of protons across a membrane, producing a proton gradient. The proton gradient is used to produce useful work.

What Is Copaxone (Glatiramer)? 343 Reviews. Copaxone is the brand name of the injectable drug glatiramer acetate, which is used to treat symptoms of relapsing forms of multiple sclerosis (MS). MS is a neurological condition where the immune system attacks the protective covering of nerves. Relapsing MS occurs when symptoms show up from time to time.opaxone is in a class of drugs known as immunomodulators, which work by stopping the body from damaging specific nerve cells. The Food and Drug Administration (FDA) approved this medicine in 1996.

Chelating Agent Definition - What does Chelating Agent mean? A chelating agent is a chemical compound that reacts with metal ions to form stable, water-soluble metal complexes. The agent rearranges the metal's chemical composition and improves the metal's general stability and likelihood to bond with other substances.

Electron acceptor In chemistry, a class of electron acceptors that acquire not just one, but a set of two paired electrons that form a covalent bond with an electron donor molecule, is known as a Lewis acid. This phenomenon gives rise to the wide field of Lewis acid-base chemistry.

What are chemoautotrophs? By strict definition, a chemoautotroph derives energy from the oxidation of reduced (usually inorganic) molecules (like H2S) and uses Carbon dioxide as its carbon source.o put it in plain English chemoautotrophs are organism (life-forms) usually made of only one cell, that can create their own food (for lack of a better word) from inorganic material around them, without using sunlight.

Chelation Definition - What does Chelation mean? Chelation is a process where in ions and molecules bind metal ions, often used as part of a decontamination and/or treatment process. Chelation commonly is done to soil, but more importantly, is commonly used to treat people. It is primarily used for medical treatment of heavy metal poisoning.

- An isolator is just a circulator with a built-in or bolted-on load (usually fairly low in power handling capability), and so as long as you stay within the power handling limits of the load then all comments below on isolators also apply to circulators and vice versa.

Resistor A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses. High-power resistors that can dissipate many watts of electrical power as heat, may be used as part of motor controls, in power distribution systems, or as test loads for generators. Fixed resistors

- “Chelated” minerals are among the mineral supplements touted for their improved absorption. The word, chelate (pronounced: key late) means to create a ring-like complex, or in loose terms ‘to grab and bond to’. Most clelated formulas use protein molecules, i.e. chains of amino acids.ut according to a WebMD.com post, Find a Vitamin or Supplement: Chelated Minerals: “Promoters sometimes market chelated minerals as dietary supplements that are superior to other mineral supplements, claiming chelated minerals are used more easily by the body (more bioavailable) than non-chelated minerals.

-   A demodulator is an electronic circuit used to recover the information content from the carrier wave of a signal.[1] The term is traditionally used in connection with radio receivers, but many other systems use many kinds of demodulators. A modulator modulates the carrier frequency, while a demodulator detects the modulation on the carrier wave and recovers the original lower frequency waveform at the destination.   For many years the modulated carrier wave was converted to a radio signal.

- All of these nerve cells send impulses back to the brain. Chemoreceptors can also be found in the brain itself, monitoring pH level and alerting the brain to the presence of chemicals which could indicate a problem.hemoreceptors are specialized nerve cells which are designed to respond to chemical stimuli. The body contains both direct and distant chemoreceptors, all of which play important roles in bodily function and daily life.

Understanding and Applying Chelated Fertilizers Effectively Based on Soil pH 1 Chela-tion keeps a micronutrient from undesirable reactions in solution and soil. The chelated fertilizer improves the bioavailability of micronutrients such as Fe, Cu, Mn, and Zn, and in turn contributes to the productivity and profitability of commercial crop production.

Chelation Chelation is useful in applications such as providing nutritional supplements, in chelation therapy to remove toxic metals from the body, as contrast agents in MRI scanning, in manufacturing using homogeneous catalysts, and in fertilizers.helate complexes are contrasted with coordination complexes composed of monodentate ligands, which form only one bond with the central atom. The word chelation is derived from Greek χηλή, chēlē, meaning claw; the ligands lie around the central atom like the claws of a lobster.
