J. Murray patented his production of " superphosphate fertilizer (a name coined by him for the product of HiSOu on phosphate rock). [Pg.474]

There are numerous natural contributors of chlorine to the stratosphere, for example, volcanic eruptions. The main concern regarding ozone destruction in recent years is associated with human activities that have increased chlorine and other synthetic chemical input into the stratosphere. At the top of the list of such chemicals are chlo-rofluorocarbons, or CFCs. CFCs are compounds that contain carbon, chlorine, and fluorine they were first developed in 1928. Common CFCs are called Freons, a trade name coined by the DuPont chemical company. CFC compounds are nonreactive, nontoxic, inflammable gases. Because of their... [Pg.265]

While today the construction of such bidentate phosphine ligands with the use of an assembly metal is referred to as supramolecular chemistry, this is not to say that there are no examples in older literature utilizing this principle. Actually, there are many and using as a search term hetero bimetallic complexes (a named coined in the early 1980s) leads us to a plethora of complexes. For instance in complex 29, reported by Rauchfuss in 1982, one would consider copper as the assembly metal and platinum as the potential catalytic metal [70]. [Pg.279]

Alkylidene. A divalent organic radical derived from an unsaturated aliphatic hydrocarbon eg, ethylidene (Hs C. CH =), poopylidene, (CHjCHjCH") etc Alkylideneperoxide. The name coined by... [Pg.130]

The first truly high-mnlecular-weight polyamide was made this way in 1935 and lead to the development of the lirsl wholly man-made fiber which became popularly known as nylon, a name coined by Du Pont for fiber-forming polyamides. Numerals representing the number of carbon atoms in lirsl the diamine and then the diacid are used to identify the nylon. Thus, poly(hexamethylene adipamide) is nylon-66 (six-six, not sixty-six), and poly(hexamethylene sebacamide) made from the 10-carbon sebacic acid is nylon-610 (six-ten). [Pg.1332]

Cnppedo- and cappedophanes are names coined by Hart et al. for systems accessible by sulfone pyrolysis, that possess an open ( cuppedo- , in 178,180, and 182) or closed ( cappedo- , in 184) molecular cavity [63]. The central phenyl ring in the m-terphenyl moiety adopts a position perpendicular to the outer, neighbouring phenyl rings, thus allowing introduction of substituents, which point into the center of the cavity, as exemplified in 182 and 184. [Pg.93]

Pentyl. Swedish name coined by the Bofors Co in the 1930 s for PETN, because the Ger name Nitropenta used at that time was not considered suitable... [Pg.615]

The Deborah number is a dimensionless number used in rheology to characterize how fluid a material is. Even some apparent solids flow if they are observed long enough. The origin of the name, coined by Markus Reiner, is the line The mountains flow before the Lord in a song by the prophetess Deborah recorded in the Bible (Judges 5 5). [Pg.214]

The solutions (8-100) and (8-102) are called the stokes let solution, apparently a name coined by Hancock.10 It is customary to choose... [Pg.547]

A generic name coined from endogenous and morphine and commonly used for all native brain peptides having essentially the opiate-hke action. [Pg.275]

Name coined by Eschenmoser for a heterocyclic ring system with a structure between that of 001110 and that of porphine. C. structures have been detected as intermediates in vitamin B 2 biosynthesis. The participating enzymes are also able to convert unnatural substrates such as uroporphyrinogen I in vitro to C. compounds The basic skeleton of factor F 430, in-... [Pg.152]

This phase was first identified by the Stockholm group, and the name coined for it was an acronym of the initial authors [26]. This phase occurs closest to the... [Pg.239]

In the early periods of carbohydrate chemistry no systematic nomenclature existed. A polysaccharide name coined at that time usually reflected the origin of the polysaccharide or sometimes emphasized some property of the isolated substance. Illustrative examples of such polysaccharide nomenclature are found in the terms cellulose, the principal... [Pg.641]

Details invention in DuPont Labs name coined commercialized ... [Pg.546]

The name coined for this class of drug was proton pump iriiibitor (PPI). After publication in 1981 of the first of a series of papers on the mechanism of action of these drugs, a variety of derivatives were synthesized that also led to the introduction of other drugs with generally... [Pg.146]

The operator in the second bracket is the ZORA Hamiltonian, and it is sandwiched by normalization operators. If we expand these operators as we did above, we get the FORA Hamiltonian as the first term. The higher terms differ, however, because the final energy in the previous series must be the Dirac energy, whereas here it is the energy for the approximate Hamiltonian. Inclusion of the normalization terms corresponds to a resummation of certain parts of the ZORA perturbation series to infinite order, and the name coined by Dyall and van Lenthe (1999) is lORA—infinite-order regular approximation. [Pg.367]

STA is the name coined to signify the simultaneous measurement of weight change (TGA) and heat change (DTA/DSC). This type of instrumentation provides several advantages over the stand-alone techniques. These are summarised as follows ... [Pg.215]

Nature makes use of the benzoquinone-hydroquinone redox couple in reversible oxidation reactions. These processes are part of the comphcated cascade by which oxygen is used in biochemical degradations. An important series of compounds used for this purpose are the ubiquinones (a name coined to indicate their ubiquitous presence in nature), also collectively called coenzyme Q (CoQ, or simply Q). The ubiquinones are substimted p-benzoquinone derivatives bearing a side chain made up of 2-methylbutadiene units (isoprene Sections 4-7 and 14-10). An enzyme system that utilizes NADH (Real Life 8-1 and 25-2) converts CoQ into its reduced form (QH2). [Pg.1013]

More recently molecular materials based on this branching idea have been produced in which the starting point is a multifunctional central molecule. Hyperbranched structures grow from this central point. Typically, each repeat unit contains a branch and a large number of identical units lie at the chain ends. This class of polymerlike materials is known as dendrimers, the name coined by Tomalia to describe a family of polyamidoamines [43]. Dendrimers are globular materials with diameters of a few nanometers making them about the size of a virus. The branched structure... [Pg.152]
