In this study, the aqueous solution method was employed to synthesize one-dimensional well-aligned ZnO nano-array on ITO glass substrate. We can find that the dimension of ZnO nanorod will changes with different growth temperature. X-ray diffraction patterns show that the nanorods are high-quality crystals growing along [001] direction with a high consistent orientation perpendicular to the sub...

A hybrid technique for the selective growth of ZnO nanorod arrays on wanted areas of thin cover glass substrates was developed without the use of seed layer of ZnO. This method utilizes electron-beam lithography for pattern transfer on seedless substrate, followed by solution method for the bottom-up growth of ZnO nanorod arrays on the patterned substrates. The arrays of highly crystalline ZnO ...

H was intentionally incorporated into as-deposited ZnO films by plasma exposure treatment. The resistivity of ZnO films was reduced to the order of 10(-3) Ω cm after H plasma treatment, and high conductive stability was identified using a post-annealing process. To find an explanation for the stable conductivity, first-principle calculation was performed. Results predicted that H atoms trapped ...

Smart chemical sensor based on CMOS(complementary metal-oxide-semiconductor) compatible SOI(silicon on insulator) microheater platform was realized by facilitating ZnO nanowires growth on the small membrane at the relatively low temperature. Our SOI microheater platform can be operated at the very low power consumption with novel metal oxide sensing materials, like ZnO or SnO2 nanostructured ma...

The use of metal oxide single crystalline nanowires for chemical sensing of pollutant gases has been proposed as a reliable solution to ensure high sensor performance due to small size of the crystallites and good stability over long term operation at high temperature. To obtain enhanced sensing capabilities of ZnO nws, we prepared composite nanostructures based on p-type NiO and n-type ZnO NWs...

We present materialization of single multicomposite nanowire (SMNW)-entrapped ZnO nanoparticles (NPs) via an electrochemical growth method, which is a newly developed fabrication method to grow a single nanowire between a pair of pre-patterned electrodes. Entrapment of ZnO NPs was controlled via different conditions of SMNW fabrication such as an applied potential and mixture ratio of NPs and a...

The objective of this study was to quantify the influence of zinc oxide nanoparticles (nanoZnO) on the water repellency and dimensional stability of beech wood. Beech wood blocks were treated with a nano-ZnO solution at four treatment levels (0, 10,000, 20,000, and 40,000 ppm) using a modified dip method. Also, a thermal treatment was performed at 60 and 120°C. After conditioning the samples, w...

A light-scattering sensor that incorporated zinc oxide (ZnO) nanoparticles was developed and characterized in this study. Evenly distributed nanostructured ZnO materials were formed on the sensing elements through the calcination of zinc acetate-treated sensing elements in a high-temperature oven. There was a large change in the scattering properties of the nanostructured ZnO materials after ad...

A fast solid-phase microextraction method using core-shell ZnO-poly (methyl methacrylate) nanobeads (ZnO-PMMA) as adsorbent was established. This fast method with high enriching efficiency and salt tolerance capability depends on the structure of the core-shell nanobeads. First, the large surface area of the PMMA shell makes the dispersive nanobeads capture samples quickly, by virtue of multi-i...
