Epitaxial YBa2Cu3O7-y (YBCO) films of 120-550 nm thickness have been prepared by fluorine-free metalorganic deposition using a metal acetylacetonate-based coating solution on yttria-stabilized zirconia (YSZ) substrates with an evaporated CeO2 buffer layer. The YBCO films were highly (0 0 1)-oriented by X-ray diffraction theta-2theta scanning and phi{symbol} scanning. The YBCO films 120-400 nm in thickness demonstrated high critical current densities (Jc) with an average in excess of 3 MA/cm2 at 77 K using an inductive method. In particular, a 210-nm-thick film showed a Jc of 4.5 MA/cm2. These excellent properties are attributed to the high crystallinity, small in-plane fluctuation due to high epitaxy and to the microstructure free from grain boundaries in the YBCO films. Further increase of film thickness increased the fraction of irregularities, i.e., precipitates and micropores, in the film surfaces, resulting in lower Jc values.

Solid-state dye-sensitized solar cells of the type TiO2/dye/ CuSCN have been made with thin Al2O3 barriers between the TiO2 and the dye. The Al2O3-treated cells show improved voltages and fill factors but lower short-circuit currents. Transient photovoltage and photocurrent measurements have been used to find the pseudo-first-order recombination rate constant (kpfo) and capacitance as a function of potential. Results show that kpfo is dependent on Va¿¿ with the same form as in TiO2/dye/electrolyte cells. The added Al2O3 layer acts as a “tunnel barrier”, reducing the kpfo and thus increasing V a¿¿. The decrease in KpfO also results in an increased fill factor. Capacitance vs voltage plots show the same curvature (a¿¼150 mV/decade) as found in Tio2dye/ electrolyte cells. The application of one AL2O3 layer does not cause a significant shift in the shape or position of the capacitance curve, indicating that changes in band offset play a lesser role in the observed Va¿¿ increase. Cells made with P25 TiO2 have, on average, 2.5 times slower recombination rate constants (longer lifetimes) than those made with colloidal TiO 2. The cells with P25 also show 2.3 times higher trap density (DOS), which results in little change in the Va¿¿ between the two types of TiO2. It is further noted that the recombination current in these cells cannot be calculated from the total charge times the first order rate constant. A 2005 American Chemical Society.

Development of an economical, well-defined and efficient electrocatalyst having a potential to replace Pt/C is crucial for oxygen reduction reaction (ORR). In this respect, we report herein one-pot wet-chemical protocol for the composition-controlled synthesis of monodisperse CuAg alloy nanoparticles (NPs) and their composition-dependent electrocatalytic activities in ORR for the first time under an alkaline condition. The presented synthetic procedure yields CuAg NPs that exhibit monodisperse size distribution with an average particle diameter of ?8 nm. Almost homogenous CuAg alloy formation is proved by using many advanced analytical techniques despite the considerable lattice mismatch between Cu and Ag. At all compositions investigated, the ORR activities of CuAg electrocatalysts are found to be significantly higher than monometallic Ag NPs. Improved ORR kinetics of CuAg alloy NPs are demonstrated by Tafel slopes (85 mV/dec for Cu30Ag70, 84 mV/dec for Cu40Ag60 and 78 mV/dec for Cu60Ag40 which are all smaller than that of monometallic Ag (113 mV/dec). Electrochemical impedance measurements support these findings and represent that charge transfer resistance strongly depends on composition of CuAg electrocatalyst. The ORR activity and surface analysis results put Cu40Ag60 forward since Cu oxidation is suppressed in Cu40Ag60 NPs, caused by Ag enhancement in the surface.

A facile, one-pot synthesis of 1H-indazoles featuring a Cu-catalyzed C?H ortho-hydroxylation and N?N bond-formation sequence with the use of pure oxygen as the terminal oxidant was developed. The reaction of readily available 2-arylaminobenzonitriles with various organometallic reagents led to ortho-arylamino N?H ketimine species. Subsequent Cu-catalyzed hydroxylation at the ortho position of the aromatic ring followed by N?N bond formation in DMSO under a pure-oxygen atmosphere afforded a wide variety of 1-(ortho-hydroxyaryl)-1H-indazoles in good to excellent yields. This efficient method does not require the utilization of noble-metal catalysts, elaborate directing groups, or privileged ligands.

Methods, adapted from photographic microcrystal growth technology, are used to assemble organized ternary organo-inorganic, nanoscale heterostructures. The resulting ensemble consists of free-standing, oriented AgBr microcrystals, upon the a¿¿111a¿¿ surfaces of which is self-assembled a monolayer of spectrally sensitizing dye, and upon the corners of the hexagonally shaped AgBr substrates are epitaxially grown nanoscale p-type CuSCN nodules. EPR spectroscopy and photophysical measurements are employed to show that the ensembles are capable of separating photogenerated geminate pairs. One of the remarkable features of this approach is that it utilizes the ultrafast kinetics of aqueous precipitation and, thus, allows the assembly of heterostructures at rates of 1010/sA·L, or greater.

A new and simple procedure for the deposition of lead (II, IV) oxide films by screen printing was developed. In contrast to conventional electrochemical methods, films can be also deposited on non-conductive substrates without any specific dimensional restriction, being the only requirement the thermal stability of the substrate in air up to 500 C to allow for the calcination of the screen printing paste and sintering of the film. In this study, films were exploited for the preparation of both photoresponsive devices and photoelectrochemical cell photoanodes. In both cases, screen printing was performed on FTO (Fluorine-Tin Oxide glass) substrates. The photoresponsive devices were tested with I-V curves in dark and under simulated solar light with different irradiation levels. Responses were evaluated at different voltage biases and under light pulses of different durations. Photoelectrochemical cells were tested by current density-voltage (J-V) curves under air mass (AM) 1.5 G illumination, incident photon-to-current efficiency (IPCE) measurements, and electrochemical impedance spectroscopy.

Copper, most commonly in the form of copper oxide, is used in the majority of marine antifoulings globally, but some paint companies do not allow their copper oxide based antifoulings to be used on aluminium hulls. This is because aluminium is more anodic in the electrochemical series than copper and if the two are in direct connect in sea water, the aluminium will corrode away. This galvanic reaction only occurs if copper metal is in direct contact with aluminium, and since modern copper oxide based antifoulings contain virtually no metallic copper there appears to be no valid reason for the ultra-cautious approach regarding the use of copper oxide based antifoulings on aluminium hulls. A number of different copper-based commercial antifoulings were applied on suitably prepared Marine-grade aluminium panels, along with an un-coated control panel. The panels were immersed in seawater. Furthermore a laboratory experiment was also undertaken where coated aluminium panels were submerged in a salt water solution as a controlled experiment. All the samples were then analysed using electron microscopy. Copper leaching out of copper oxide based antifoulings had no effect on the corrosion of Marine-grade aluminium.
