in the past decades, many methods have been developed to synthesize zero- dimensional  nanoparticles, quasi–one–dimensional (1d) cuo nanostructures, such as metal organic deposition technique,  microwave irradiation, sol-gel-like dip  technique, reverse micelle-assisted route, chemical method, and simple template free solution route. among those synthesis methods, hydrothermal and chemical reac...

Technique has been developed to fabricate ordered arrays of microcontainers. We report that ordered microcontainer arrays of Cu can be fabricated on glass substrate by thin film deposition and self-assembly technology. In addition, CuO nanowires are found to grow only in the inner sides of microcontainers, which verifies the stress growth mechanism of CuO nanowires. High-resolution transmission...

We report on the application of Raman scattering as a probe to study 4-mercaptopyridine (4-Mpy) surface-modified CuO nanocrystals. Enhanced Raman scattering from 4-Mpy adsorbed on CuO nanocrystals was observed. The Raman signals displayed 10(2) enhancement compared with those of 4-Mpy in solution. We compared the Raman spectra of 4-Mpy molecules adsorbed on CuO nanocrystals and Ag, Cu substrate...

Experimental investigations of heat transfer coefficient of CuO/Water nanofluid are reported in this paper. The heat transfer coefficient of the CuO/water was measured with the help of double pipe heat exchanger. The nanofluid was prepared by dispersing a CuOnano particle in deionized water. CuO/water nanofluid with a nominal diameter of 27nm at different volume concentrations (0.1 &0.3 vol.%) ...

In this article, a wet chemical method was developed to prepare stable CuO nanofluids. The influences of synthesis parameters, such as kinds and amounts of copper salts, reaction time, were studied. The thermal conductivities of CuO nanofluids were also investigated. The results showed that different copper salts resulted in different particle morphology. The concentration of copper acetate and...

H2S gas sensing response characteristics of bare SnO2 thin films and heterostuctures with nanolayer (10 nm) of Cu and CuO are studied. Changes in resistance values, occurring with integration of Cu and CuO nanolayers on SnO2 is acquired real-time, and compared. Rise in sensor resistance after introduction of Cu and CuO nanolayers on SnO2 sensing layer is understood to enhance the sensing respon...

The effects of nano particles of CuO on voltage-dependent potassium currents were studied in acutely isolated CA1 pyramidal neurons of rat hippocampus using the whole-cell patch-clamp techniques. Nano particles of CuO had small effects on transient outward potassium current (I(A), no statistical significance) and mainly inhibited delayed rectifier potassium current (I(K)) in the concentration o...

Highly efficient tree branch-shaped CuO photocathodes are fabricated using the hybrid microwave annealing process with a silicon susceptor within 10 minutes. The unique hierarchical, one-dimensional structure provides more facile charge transport, larger surface areas, and increased crystallinity and crystal ordering with less defects compared to irregular-shaped CuO prepared by conventional th...

A high temperature electrochemical oxidation process has been used to produce large single crystals of La 2 CuO 4+δ suitable for neutron scattering experiments. Below room temperature the oxygen-rich phases have structural superlattice scattering peaks which indicate new period-icities ranging from 2 to 6.6 layers perpendicular to the copper oxide planes. A model structure originally proposed f...
