Title of Document: COPPER OXIDE NANOARCHITECTURES FOR PHOTOELECTROCHEMICAL HYDROGEN GENERATION Chia-Ying Chiang, Doctor of Philosophy, 2012 Directed By: Professor Sheryl H. Ehrman, Department of Chemical and Biomolecular Engineering Hydrogen is a high-quality energy carrier, similar to electricity, which can be used with high efficiency and near-zero emissions at the point of use. The most prom...

A non-invasive method for detecting glucose is pursued by millions of diabetic patients to improve their personal management of blood glucose. In this work, a novel CuO nanoparticles (NPs) decorated polycaprolactone@polypyrrole fibers modified indium-tin oxide (denoted as CuO/PCL@PPy/ITO) electrode has been fabricated by electrospinning combined with the electrodeposition method for non-enzymat...

Here we report a very simple method to convert conventional CuO powders to nanoparticle interlinked microsphere cages by solution method. CuO is dissolved into aqueous ammonia, and the solution is diluted by alcohol and dip coating onto a glass substrate. Drying at 80 C, the nanostructures with bunchy nanoparticles of Cu(OH)2 can be formed. After the substrate immerges into the solution and we ...

In recent years, fabrication of metal oxide nanoparticles is intensively gaining the interest of various chemists as well as biochemist due to their applications in different fields. Among all the transition metal oxides, CuO and ZnO are the important metal oxide nanoparticles exhibiting tremendous properties and a wide range of applications. Both CuO and ZnO nanoparticles were prepared by comb...

Stable alkyne-capped copper nanoparticles were prepared by chemical reduction of copper acetate with sodium borohydride in the presence of alkyne ligands. Transmission electron microscopic measurements showed that nanoparticles were well dispersed with a diameter in the range of 4e6 nm. FTIR and photoluminescence spectroscopic measurements confirmed the successful attachment of the alkyne ligan...

Biomolecule-mediated nanoparticle synthesis has recently the gained attention of researchers due to its ecofriendly and non-toxic nature. Metabolites from plant extracts represent a better alternative to chemical methods to fulfill the growing demand for non-hazardous nanoparticle synthesis routes. Selenium and its nanoparticles have an extensive range of applications. Thus, biofabrication of s...

OBJECTIVES This study focused on determining cytotoxic effects of copper oxide nanoparticles (CuO NPs) on chronic myeloid leukemia (CML) K562 cell line in a cell-specific manner and its possible mechanism of cell death. We investigated the cytotoxicity of CuO NPs against K562 cell line (cancerous cell) and peripheral blood mononuclear cell (normal cell). MATERIALS AND METHODS The toxicity was...

In nanotoxicology, the capacity of nanoparticles of the same composition but different shape to induce cytotoxicity and genotoxicity is largely unknown. A series of cytotoxic and genotoxic responses following in vitro exposure to differently shaped CuO nanoparticles (CuO NPs, mass concentrations from 0.1 to 100 μg/ml) were assessed in murine macrophages RAW 264.7 and in peripheral whole blood f...
