Life cycle assessment of algal biofuels

Creator:: Kirby, Bryan L.
Abstract:: This thesis consists of three studies to better understand the environmental sustainability potential for algal-based biofuels. Initially, a comparison of recent life cycle assessments (LCA) of theoretical full-scale algal biofuel facilities was developed. These studies include varying boundaries and scope, functional units, and technology maturity assumptions. The comparison converted results...

Suppression of Met signaling by the green tea polyphenol (-)-epigallocatechin-3-gallate (EGCG)

Creator:: Larsen, Christine A.
Abstract:: Met is a prognostic indicator of colorectal cancer patient survival. Therapies that target Met may therefore have beneficial outcomes in the clinic. Recently, EGCG was reported to suppress Met activation, although the mechanisms were not elucidated. HCT116 and HT29 human colon cancer cells were used to examine the relationships between...

Atropisomeric 8,8'-biquinolyl derivatives : synthesis, properties and applications

Creator:: Milicevic, Selena D.
Abstract:: 7,7'-Dihydroxy-8,8'-biquinolyl (azaBINOL) was prepared from 7-hydroxyquinoline via N,N-dimethyl O-quinol-7-yl carbamate by directed ortho-metallation followed by FeCl₃-mediated oxidative coupling of the 8-lithioquinoline intermediate. Saponification of the resulting dicarbamate provided crystalline (±)-azaBINOL in 56% overall yield. 6,6'-Bis(dimethylaminocarbonyl)-7,7'-dihydroxy-8,8´-biquinolyl was prepared from the same dicarbamate by a double anionic-Fries rearrangement in 43% yield. 7,7'-Bis(diethylamino-carbonyloxy)-6,6'-diiodo-8,8´-biquinolyl...
