What Happens to the Where, When and How in Malay?

Description: In this thesis, I analyze three positions of the wh-word in Malay and attempt to explain what accounts for the differences between them. Specifically, I consider if the movement of the wh-interrogative is really wh-movement or if something else is going on. In regard to the the in-situ wh-words and the partially moved wh-words, I consider whether these move covertly and if they do, if this is feature movement or covert phrasal movement.

Synthesis and characterization of molecules to study the conformational barriers of fluorocarbon chains

Description: Fluorocarbons are known to be stiffer than their hydrocarbon analogues, a property that underlines the extensive industrial application of fluorocarbon materials. Although there has been previous studies on the rotational barrier of molecules having fluorocarbon centers, a detailed systematic study is necessary to quantify flurocarbon stiffness. The molecules, Pyrene-(CF2)n-Pyrene, Pyrene-(CF2)n-F, Pyrene-(CH2)n-Pyrene and Pyrene-(CH2)n-H were therefore synthesized to enable the determination o… more
