In compositional names

Ending of names of formally electronegative homoatomic constituents in compositional names, e.g. disulfur dichloride. Cf. Section IR-5.4. 

The term HN3 is also used when a distinction between reaction forms is not practical. DN3 has the names deuterazoic acid or deuterium azide, respectively. Inorganic derivatives of HN3 are called azides or, in composite names, azido compounds. 

Calcium Hypochlorite. High assay calcium hypochlorite [7778-54-3] was first commercialized in the United States in 1928 by Mathieson Alkali Works, Inc. (now Olin Corp.) under the trade name HTH. It is now produced by two additional manufacturers in North America (Table 5). Historically, it usually contained about 1% water and 70—74% av CI2, so-called anhydrous product, but in 1970, a hydrated product was introduced (234). It is similar in composition to anhydrous Ca(OCl)2 except for its higher water content of about 6—12% and a slightly lower available chlorine content. This product has improved resistance to accidental initiation of self-sustained decomposition by a Ht match, a Ht cigarette, or a small amount of organic contamination. U.S. production in the 1990s consists primarily of partially hydrated Ca(OCl)2, which is sold as a 65% av CI2 product mainly for swimming pool use. Calcium hypochlorite is also sold as a 50% av CI2 product as a sanitizer used by dairy and food industries and in the home, and as a 32% product for mildew control. 

Curare was first examined by Roulin and Boussingalt, who isolated a syrupy body, which they named curarine much later a similar substance was obtained by Buchner, - and in 1865 Preyer announced that he had obtained curarine and its salts in a well-crystallised condition, and by analysis of the platinichloride, ascertained its composition to be C10H35N. Sachs - was only able to obtain an amorphous alkaloid, to which he assigned the formula CigHjjN. The work of Boehm explained to some extent these discrepant results he examined all three varieties and showed that they differed in composition, and that the isolation of the various curarines as single substances required special processes. 

The rheological behavior of storage XGs was characterized by steady and dynamic shear rheometry [104,266]. Tamarind seed XG [266] showed a marked dependence of zero-shear viscosity on concentration in the semi-dilute region, which was similar to that of other stiff neutral polysaccharides, and ascribed to hyper-entanglements. In a later paper [292], the flow properties of XGs from different plant species, namely, suspension-cultured tobacco cells, apple pomace, and tamarind seed, were compared. The three XGs differed in composition and structural features (as mentioned in the former section) and... 

Plastic explosives vary in composition and go by different names. The U.S. military has two versions C-3 and C-4. The British call theirs PE-2 and the Italians T-4. Other names used are RDX and, especially in Europe, Hexagen and Cyclonite. 

In 62, two zincate ions of different composition, namely [Zn(CCPh)3] 62a and its THF adduct [Zn(CCPh)3(THF)] 62b, co-crystallized (Figure 31). Both, the coordination of only one zincate ion with THF and the trigonal-pyramidal structure of 62b, show that the interaction between zinc and the THF molecule in 62b must be weak. The zinc-carbon bonds in 62a and 62b are 1.967(7) and 2.003(5) A long, respectively. 

As mentioned above, the name haptoglobin was coined to designate plasma components forming stable Hb complexes in which the Hb has acquired the properties of peroxidase. To describe an unidentified substance simply by the properties of its complexes with only one other substance is unsatisfactory. Hp as well as Hb from different species will presumably vary to some extent in composition, in the stability of their complexes, and in their peroxidase properties. Thus dog Hp, for example, links human or dog Hb, but the latter Hb complex shows only weak peroxidase activity in Jayle s conventional peroxidase test (N5). 

Dye-doped polymeric beads are commonly employed in different formats (Fig. 5), namely as water-dispersible nanosensors, labels and in composite materials (DLR-referenced and multianalyte sensors, sensor arrays, magnetic materials, etc.). The sensing properties of the dye-doped beads are of little or no relevance in some more specific materials, e.g., the beads intended for photodynamic therapy (PDT). The different formats and applications of the beads will be discussed in more detail in the following section, and the relative examples of sensing materials will be given.

The fuel-bed composition has a significant effect on the thermochemical conversion behaviour. The composition is in reality a very complex variable and can be divided into fuel chemistry and fuel physics of the individual fuel particles making up the bed. These authors will make a drastic simplification and define only two degrees of fuel-bed composition, namely a homogeneous or a heterogeneous fuel bed. In this review the terms homogeneous and heterogeneous are used in a relative and practical way. However, they could be described as two extreme cases as well [9]... 

For a start, the pattern of an atmospheric composition and situation, i.e., a data vector catprising all available physical and/or chatiical data pertaining to that situation, is positioned in a multidimensional feature space that is spanned by all physical (i.e., meteorological) and chanical (i.e., compositional) named features. 

Specialists in nomenclature recognise two different categories of nomenclature. Names that are arbitrary (including the names of the elements, such as sodium and hydrogen) as well as laboratory shorthand names (such as diphos and LithAl) are termed trivial names. This is not a pejorative or dismissive term. Trivial nomenclature contrasts with systematic nomenclature, which is an assembly of rules, themselves arbitrary. The function of specialists in nomenclature is to codify such rules so that everyone can use them to identify pure substances, rather like many of us use an alphabet to represent words. There may be more than one way to name a compound or species, and no one way may be superior to all the others. Names also vary in complexity, depending upon how much information needs to be conveyed. For example, a compositional name conveys less information than a structural (or constitutional) name, because this includes information about the arrangement of atoms in space. 

When it is required to convey more information than is implied by a simple compositional name, other approaches to name construction are adopted. The structure of the compound under consideration generally dictates the name adopted, even though a compound may be named correctly in more ways than one. For molecular compounds, substitutive nomenclature, originally developed for naming organic compounds and the oldest systematic nomenclature still in use, is generally used. 

A promising detection principle utilizes similar nebulization procedure as applied in ELS, namely the corona-charged aerosol detectors, CAD. In CAD, the aerosol particles interact with an ionized gas (usually nitrogen). The particles become charged and electrically detected [294]. It has been shown that the response of CAD does not depend on the nature of analyte. On the other hand, the size of the aerosol depends on the mobile phase composition and it has to be calibrated.
