X may also be hydroxyacids such as glycolic acid; ester alcohols such as 2,2,4-Trimethyl-1,3-pentanedial monoisobutyrate, Texanol® available from Eastman Chemicals; and other solvents that are not classified as VOCs per European Union Directive 2004/42/EC are included....
The components that are in common between the four optima surrogates are i-pentane, toluene and 1-2-4-trimethylbenzene. It is highlighted that the representation of aromatics required the most various composition. The detailed composition of the optima surrogates is released in Table A2. In ...
Even though the characterization of the molecular structures of the compounds of the type Me2Si(pyX)2 has been missing in the literature so far, compound Me2Si(pyO)2 (2a) had been mentioned in a patent already [60], but it was proposed to feature hexacoordinate Si with chelating pyO liga...

The various isomers of C7H16 are written as required and named after the systematic nomenclature: The number of carbon atoms in the main chain is 7, and the number of carbon atoms in the main chain is 6 The number of carbon atoms in the main chain is 5 and the number of carbon ...
The octane scale arbitrarily defines n-heptane a value of 0, and isooctane (2,2,4-trimethyl pentane) an octane number of 100. Isooctane is then added to heptane until the mixture has the same knock characteristics as the fuel being tested, and the percent isooctane is taken as the unknown...
Only few studies in literature [1,14,27,28] have faced the problem of diffusion through the sampling bags by calculating the diffusion coefficient of the inspected chemical compound. Moreover, in most studies, the amount of chemical compound lost due to adsorption on the polymeric film has been...
compound of interest of this latter type is flurbiprofen which is 2-(2-fluoro-4-biphenylyl)propionic acid. Thus, a large variety of 2-aryl-C3to C6-alkanoic acids, and particularly the 2-arylpropionic acid drug compounds are known and more of such compounds will undoubtedly be discovered and...

Since this sensor type operates with a closed circuit, multiple cells can be connected in series, with each of them being selective for a specific compound. The main advantage of this sensor type is its ability to form complex structures, allowing the simultaneous analysis of several different ...
