Title of Document: NEW ELECTROLYTE AND ELECTRODE MATERIALS FOR USE IN LITHIUMION BATTERIES Veidhes R. Basrur, Master of Science, 2010 Directed by: Prof. Srinivasa R. Raghavan & Prof. Chunsheng Wang Department of Chemical & Biomolecular Engineering Lithium-ion batteries have emerged as the preferred type of rechargeable batteries, but there is a need to improve the performance of the electrolyte...

Beta,beta-dimethyl acryl shikonin is an extract from the root of plant Arnebia nobilis which has been shown to possess anti-cancer activity. However, its toxicity limited further development of shikonin as a therapeutic agent. Subsequently, several analogues of beta,beta-dimethyl acryl shikonin were synthesized. One of these analogues, shikonin 93/637 was found to be significantly less toxic co...

OBJECTIVE To assess the influence of variable factors such as the size of the airway and the CT imaging parameters such as the reconstruction kernel, field-of-view (FOV), and slice thickness on the automatic measurement of airway dimension. MATERIALS AND METHODS An airway phantom was fabricated that contained eleven poly-acryl tubes of various lumen diameters and wall thicknesses. The measure...

two new samples of poly(amide-imide)/nanocomposites containing bicyclo segment and dibenzalaceton moiety in the main chain were synthesized by a solution intercalation technique. poly(amide-imide) (pai) 8 as a source of polymer matrix was synthesized by the direct polycondensation reaction of n,n´-bis(4-carboxyphenyl)bicyclo[2,2,2]oct-7-ene-2,3,5,6-tetracarboxylic diimide 3 with 2,6-bis(4-amino...

some amide derivatives have been synthesized by the reaction of corresponding nitriles with potassium tert-butoxide as a nucleophilic oxygen source under ultrasonic irradiation. this new methodology provides good to excellent yields in short reaction times (15-90 min) at room temperature.

Previous studies have revealed that the glucoincretin hormone glucagon-like peptide-1 (GLP-1)(7-36)amide is metabolized by dipeptidyl peptidase-IV (DPP-IV) and neutral endopeptidase 24.11 (NEP) to yield GLP-1(9-36)amide and GLP-1(28-36)amide, respectively, as the principal metabolites. Contrary to the previous notion that GLP-1(7-36)amide metabolites are pharmacologically inactive, recent studi...

one pot solvent less synthesis of amidoalkylnaphthol derivatives via reaction of aldehydes, 2-naphthol and acetamide/urea in the presence of phenylphosphinic acid is  described. this methodology provides a simple synthetic route to amidoalkylnaphthols in good to high yields.

In the present work, a novel interpenetrating polymer network (IPN) hydrogel composed of crosslinked chitosan and poly(acryl acid) was prepared by crosslinking using glutaraldehyde. The model drug, cis-platin, was loaded into the resulted IPN hydrogel. Water absorption of the hydrogel could be switched on and off swiftly by control of pH of the surrounding environment. Therefore, the synthesize...
