“…For this temperature, conversely to that found at 300 °C, NO exposure resulted in an increase in conductance. This particular response pattern to NO at high temperatures (increase in with [NO]) has been observed before for NO x monitoring studies using n-type semiconducting metal-oxides [12,[35][36][37][38]. It is noteworthy that the presence of low concentrations of nitric oxide resulted in an increase in electronic conductance (Figure 7), which is the response pattern commonly found for perovskite oxides (p-type materials) when an interaction with oxidizing gases, including molecular O 2 , takes place [39].…”

“…A transient response upon NO x exposure was not reported in this research account. Similarly, the physical chemical nature of the transient response has been discussed for the interaction of NO x with CuO thin-films [35]. Because a rise in electronic conductance often originates from an increase in the concentration of charge carriers [19,22,[24][25]28], the combined action of both temperature and chemical interaction between gas-phase species (NO x ) and the thin-film surface could have caused an increase in the concentration of change carriers (e.g.…”

Copper oxide nanoparticles (CuO-NPs) were synthesized via chemical precipitation method using copper (II) chloride dihydrate and sodium hydroxide. Then nanoparticles were characterized by using X-ray Diffraction (XRD), Scanning Electron Microscope (SEM), Energy Dispersive X-ray (EDX), and Fourier Transform Infra Red (FTIR) spectroscopy. The XRD patterns and EDX spectra showed that the prepared CuO-NPs were highly pure, crystalline and nano-sized. The SEM image suggested that nano particles were spherical and there was a tendency of agglomerations. The nanoparticles showed interactions between copper and oxygen atoms supported by FTIR studies.

A simple thermal oxidation of Cu thin films deposited on planar substrates established a growth of vertically aligned copper oxide (CuO) nanorods. DC sputter-deposited Cu thin films with various thicknesses were oxidized in environments of various oxygen partial pressures to control the kinetics of oxidation. This is a method to synthesize vertically aligned CuO nanorods in a relatively shorter time and at a lower cost than those of other methods such as the popular hydrothermal synthesis. Also, this is a method that does not require a catalyst to synthesize CuO nanorods. The grown CuO nanorods had diameters of ~100 nm and lengths of 1~25 µm. We examined the morphology of the synthesized CuO nanorods as a function of the thickness of the Cu films, the gas environment, the oxidation time, the oxidation temperature, the oxygen gas flow rate, etc. The parameters all influence the kinetics of the oxidation, and consequently, the volume expansion in the films. Patterned growth was also carried out to confirm the hypothesis of the CuO nanorod protrusion and growth mechanism. It was found that the compressive stress built up in the Cu film while oxygen molecules incorporated into the film drove CuO nanorods out of the film.
