In this work, we report a method to process porous silicon to improve its chemical resistance to alkaline solution attacks based on the functionalization of the pore surface by the electrochemical reduction of 4-nitrobenzendiazonium salt. This method provides porous silicon with strong resistance to the etching solutions used in optical lithography and allows the fabrication of tailored metalli...

The FM01-LC is a laboratory-scale, electrochemical filter-press cell with a projected electrode area of 64 cm and a rectangular electrolyte flow channel which was originally based on the larger FM21-SP electrolyser of 2100 cm projected electrode area designed for the chlor-alkali industry then diversified to other applications. Many laboratories and industries have utilised this type of control...

The generation of key drug metabolites for the purpose of their complete structural characterization, toxicity testing, as well as to serve as standards for quantitative studies, is a critical step in the pharmaceutical discovery and development cycle. Here, we utilized electrochemistry/mass spectrometry for the detection and subsequent generation of six phase I metabolites of simvastatin and l...

The synthesis and characterization of the clusters Au13[PPh3]4[S(CH2)11CH3]2Cl2 (1) and Au13[PPh3]4[S(CH2)11CH3]4 (2) are described. These mixed-ligand, sub-nanometer clusters, prepared via exchange of dodecanethiol onto phosphine-halide gold clusters, show enhanced stability relative to the parent. The characterization of these clusters features the precise determination of the number of gold ...

The synthesis, characterization and evaluation in solid-state devices of a series of 8 cationic iridium complexes bearing different numbers of methoxy groups on the cyclometallating ligands are reported. The optoelectronic characterization showed a dramatic red shift in the absorption and the emission and a reduction of the electrochemical gap of the complexes when a methoxy group was introduce...

The lithium-sulfur (Li-S) battery promises with its high theoretical capacity (1675 mA h) and energy density (2600 Wh kg) to be one of the energy storage systems of the future. However, the electrochemical processes and degradation mechanisms of the cells need further investigation to improve their capacity and safety. In this work, in-situ characterization methods were applied for the characte...

Polypyrrole (PPy) nanofibers have been fabricated on glassy carbon electrode (GCE) usingelectrochemical technique. Electropolymerization of pyrrole (Py) for the fabrication of PPy nanofiberswas occurred on GCE by applying a fixed potential of about 0.85 V for 120 sec in a mild basic solutioncontaining sodium carbonate and sodium perchlorate. In the mild basic media, the monomer, Py, isoxidized ...

Title of Document: MODEL DEVELOPMENT FOR GADOLINIADOPED CERIA-BASED ANODES IN SOLID OXIDE FUEL CELLS Lei Wang, Doctor of Philosophy, 2014 Directed By: Professor Gregory S. Jackson, Department of Mechanical Engineering Intermediate temperature (500 700 °C) solid oxide fuel cells (IT-SOFCs) with gadolinia-doped ceria (GDC) electrolytes have significant commercial potential due to reduced material...

A new concept for the localized characterization of gas evolving electrodes based on scanning electrochemical microscopy (SECM) is suggested. It offers information about the spatial distribution of the predominant locations, which represent the most active catalytic sites, and dynamic characteristics of gas-bubble departure. The knowledge about gas-bubble departure is critical for the assessmen...
