Zinc oxide (ZnO) nanostructure was successfully synthesized on an alumina substrate by the hydrothermal method. The method consists of two stages: preparation seeding layers and growth ZnO nanostructures. 0.4 M Acetate Dihydrate (Zn(CH3COO)2·2H2O) 3 Sodium Hydroxide (NaOH) were used as precursors. process carried out at 90 °C for 4 hours. Morphological characterization nanostructures conducted ...

We propose a novel mechanism to construct a tunable and ultracompact refractive index sensor by using the Fano resonance in metal-graphene hybrid nanostructure. Plasmon modes in graphene nanoribbons and waveguide resonance modes in the slits of metal strip array coexist in this system. Strong interference between the two different modes occurs when they are spectrally overlapped, resulting in a...

cupric oxide nanostructures were synthesized via a simple reaction between copper nitrate and sodium hydroxide using a sonochemical-assisted method. the synthesized cuo was then characterized using x-ray diffraction, scanning electron microscopy, transmission electron microscopy, fourier transform infrared, ultraviolet-visible and photoluminescence spectroscopy. our studies show that the cuo na...

ilicon Carbonitride (SiCN) is a novel polymer derived ceramic material, which is not only mechanically, chemically and thermally robust, but also possesses functional properties. These properties yields SiCN as an excellent choice for sensor applications in high temperatures with harsh chemical conditions. The principal objective of the research is to develop the underlying materials science fo...

Nickel oxide has been widely used in chemical sensing applications, because it has an excellent p-type semiconducting property with high chemical stability. Here, we present a novel technique of fabricating three-dimensional porous nitrogen-doped nickel oxide nanosheets as a highly sensitive NO₂ sensor. The elaborate nanostructure was prepared by a simple and effective hydrothermal synthesis me...
