Structure-property studies of conjugated 1,8-naphthalic anhydrides
… work in this thesis focuses on investigating the structure-property relationships of conjugated 1,8-naphthalic anhdyrides. Two series of compounds, substituted at the 3- and 4-position of the naphthalic core were designed and synthesized using a variety of aryl groups with different donor …

Catechyl-lignin tissues in Vanilla orchid and Candlenut: structure/property studies
… due to its highly linear-homopolymer structure. The ability of some seed coats/nutshells in angiosperms to synthesize a new type of lignin is another level of lignin evolution. However, the role of C-lignin related to the function of the seed coat is unclear while it exhibits different …

Processing-Structure-Property Studies of: I) Submicron Polymeric Fibers Produced By Electrospinning and II) Films Of Linear Low Density Polyethylenes As Influenced By The Short Chain Branch Length In Copolymers Of Ethylene/1-Butene, Ethylene/1-Hexene & Ethylene/1-Octene Synthesized By A Single Site Metallocene Catalyst
… this dissertation has been to explore processing-structure-property relationships for submicron polymeric fibers produced by electrospinning (Part I) and to ascertain whether or not the length of the short chain branch has any effect on the physical properties of films of linear low-density …

Structure-property behavior of sol-gel derived hybrid materials
Structure-property studies were carried out on a number of different hybrid sol·gel materials. Multifunctional silicon ethoxides were prepared and studied by solid state ²⁹Si NMR and Raman spectroscopy to determine the type of silicate structures formed and the degree of conversion attained by the …

Mesoporous silica encapsulated metal nanoparticles in catalysis
… with defined stoichiometry and ordered crystal structure, which exemplifies them as ideal model catalysts for structure-property studies in catalysis. Direct colloidal synthesis of intermetallic nanoparticles requires the presence of organic capping agents, which limits the thermal stability of …
