Comparison Of Liquid-Liquid Extraction And Solid Phase Extraction Of Mephedrone, Brittany Simone Love
Comparison Of Liquid-Liquid Extraction And Solid Phase Extraction Of Mephedrone, Brittany Simone Love
Master's Theses
Legal high drugs are modified scheduled drugs. As with any new drug, researchers have to conduct studies to gather information about the drug. The problem with obtaining accurate information on new drugs is that by the time information is gathered, drug abusers and street chemists have developed new ones. Comparing designer drugs to their illegal counterparts is often helpful in that it can provide a starting point. Mephedrone is a new designer drug that has become a problem over the past few years. Often marketed as bath salts and plant food, mephedrone has become the knockoff replacement for amphetamines. This …
Growth And Carboxysome Composition Of The Csosia Pore Mutants Of Halothiobacillus Neapolitanus, Jenifer Milam
Growth And Carboxysome Composition Of The Csosia Pore Mutants Of Halothiobacillus Neapolitanus, Jenifer Milam
Master's Theses
Carboxysomes are specialized organelles that are filled with ribulose 1,5- bisphosphate carboxylase/oxygenase (RubisCO) needed for CO2 fixation. The major carboxysome shell proteins, CsoSl A, B, and C, form hexamers which tile together to form the facets of the thin shell. Each hexamer has a small central pore that may play a role in metabolite flux. Using predicted structural models, a specific amino acid within the conserved hexamer pore motif (Phe-Val-Gly-Gly-Gly-Tyr) was chosen to change the size and charge of the pore, respectively. Two mutants of Halothiobacillus neapolitanus were generated in which the wild type csoSJA gene was replaced with the …
Direct Chain-End Functionalization Of Living Polyisobutylene With Phenoxyalkyl(Meth)Acrylates, Conor Patrick Roche
Direct Chain-End Functionalization Of Living Polyisobutylene With Phenoxyalkyl(Meth)Acrylates, Conor Patrick Roche
Master's Theses
This volume describes efforts toward the synthesis and employment of phenoxyalkyl (meth)acrylates, which were used to end-quench 1sobutylene polymers m1tiated from 2-chloro-2,4,4-tnmethylpentane (TMPCl), and 5-tert-butyl-1 ,3-d1(1-chlorol- methylethyl)benzene (bDCC), respectively, at -70 °C in 40/60 (v/v) hexane/methyl chlonde. The quencher/cham end molar rat10s typically ranged from 2.5-4, while the ratio of Lewis ac1d/cham end was vaned from approximately 3 5-6 In all cases, alkylation occurred exclusively at the para position of the quencher and no cham degradat10n was observed, even at high concentrations of TiC14 and long reaction times. Prellmmary qualitative studies mvolved the reaction of quenchers of varymg alkyl tether …
