Commercial naphthas are complex mixtures of a large number of different isomers and are generally characterized by specific gravity and boiling curves (TBP curves or ASTM D86). The relevant properties of different straight run naphthas are reported in Table VIII. The sulphur content is usually lower than 2% and nitrogen is in the order of a few ppm. Light and heavy naphthas are... 

Many relevant properties and already commercially available applications of ceramic superconductors are listed in Tables 9.7 and 9.8 it is important to note that LTS operate at low temperatures, close to 4K (liquid helium), while HTS operate from the temperature of liquid helium to 77 K (liquid nitrogen). Although limited details of these materials are described in the following sections, the electronic applications which often employ thin films or type 1 superconducting metals have been partly omitted.
