degree of branching
1Branching (linguistics) — In linguistics, branching is the general tendency towards a given order of words within sentences and smaller grammatical units within sentences (such as subordinate propositions, prepositional phrases, etc.). Such ordering and nesting of phrases …
2Hierarchy — A hierarchy (Greek: hierarchia (ἱεραρχία), from hierarches, leader of sacred rites ) is an arrangement of items (objects, names, values, categories, etc.) in which the items are represented as being above, below, or at the same level as one… …
3Polymer — Appearance of real linear polymer chains as recorded using an atomic force microscope on surface under liquid medium. Chain contour length for this polymer is 204 nm; thickness is 0.4 nm.[1] A polymer is a large molecule (macromolecule …
4Polyethylene — or polythene (IUPAC name poly(ethene)) is a thermoplastic commodity heavily used in consumer products (notably the plastic shopping bag). Over 60 million tons of the material are produced worldwide every year. Description Polyethylene is a… …
5Organic chemistry — Structure of the methane molecule: the simplest hydrocarbon compound. Organic chemistry is a subdiscipline within chemistry involving the scientific study of the structure, properties, composition, reactions, and preparation (by synthesis or by… …
6Colloidal crystal — A colloidal crystal is an ordered array of colloid particles, analogous to a standard crystal whose repeating subunits are atoms or molecules.[1] A natural example of this phenomenon can be found in the gem opal, where spheres of silica assume a… …
7Polymerization — An example of alkene polymerization, in which each Styrene monomer unit s double bond reforms as a single bond with another styrene monomer and forms polystyrene. In polymer chemistry, polymerization is a process of reacting monomer molecules… …
8Radical polymerization — is a type of polymerization in which the reactive center of a polymer chain consists of a radical.The polymerization reaction is initiated by three classes of free radical initiators: * certain compounds that can be broken down in two radicals at …
9Glucomannan — Propolene redirects here. It is not related to propylene. Glucomannan is a water soluble polysaccharide that is considered a dietary fiber. Glucomannan is a food additive used as an emulsifier and thickener. Products containing glucomannan,… …
10Concurrent tandem catalysis — (CTC) is a technique in chemistry which uses multiple catalysts on a single molecule in a one pot vessel to produce a product otherwise not accessible by a single catalyst. (see one pot synthesis) The scheme below illustrates this process.… …
