Synthesis and analysis of polyphenyl compounds and their derivatives
This thesis is concerned with the study of polyphenyl compounds and their derivatives, and throughout the work is the overarching theme of analysis and understanding of complex mixtures. The analysis of complex mixtures is not only an academic pursuit but something of value to industry. Individual …

Structure vs. Properties Using Chemical Graph Theory
… and its applications. We first look at tree-like polyphenyl systems, which form an important family of compounds in Chemistry, particularly in Material Science. The importance can be seen in LEDs, transmitters, and electronics. In recent years, many extremal results regarding such systems under …

The terpenes of Virginia pine (<u>Pinus virginiana mill</u>.), with investigations of their attractancy to the southern pine beetle (<u>Dendroctonus frontalis</u> zimm.)
… phases of different polarity, Carbowax 20M and polyphenyl ether + Igepal + Versamid-9JO, were used predominantly for analytical determinations. However, a S.C.O.T. column coated with UCON LB550X stationary phase, was used for measuring some compounds. The monoterpenes of Virginia pines were …
