New Enantioselective Lewis Acid Catalysts, Mustafa Guzel Dec 1996

New Enantioselective Lewis Acid Catalysts, Mustafa Guzel

All Theses

Recently, many organic chemists have been ultimately interested in research in the synthesis of enantiomerically pure organics which are useful to synthesis of biologically active agents and prodrug substances. In the past decades, the new concepts in catalyst design unexpectedly explored the direction of natural product synthesis. In many cases, using enantioselective catalysts are the most suitable and efficient method into enantiopure systems.

Theoretical And Empirical Investigation Into Polymer Blend Morphology In Fiber Spinning, Ajay D. Padsalgikar Aug 1996

Theoretical And Empirical Investigation Into Polymer Blend Morphology In Fiber Spinning, Ajay D. Padsalgikar

All Dissertations

A promising way of developing new fiber forming materials is by utilization of polymer blends. The morphology of polymer blends has a significant effect on the properties of the resultant fiber. Morphological studies have shown that immiscible additives remain dispersed in the matrix as suspended droplets and that the droplets are elongated into fibrils under the action of shear or extensional forces during processing. The deformability of the dispersed phase is a controlling factor in deciding the resultant morphology and thereby the fiber properties. We report the results of a study of droplet deformation in uniaxial elongational flow under non …
