In this study, we reported the synthesis of pure ZnO and Mg-doped (Mg-ZnO) nanoparticles by simple co-precipitation method studied ethanol sensing activity synthesized nanostructures. XRD analysis illustrates that (NPs) possess hexagonal wurtzite structure average crystallite size is calculated to be 29 nm 33 nm, respectively. The FT-IR spectra NPs confirm presence bands appeared near 400 cm-1 ...

Abstract Developing delicate methods to synthesize well-controlled nanostructures is diffusely recognized as a potent tool enhance photocatalysts’ performances in various photoreactions. Herein, phase-controlled CdS hierarchical were synthesized using MOF-templated strategy, where Co-MOF nanospheres used the starting material, followed by two steps of sulfidation and cation exchange. By rationa...

We describe a method to predict and control the lattice parameters of hexagonal and gyroid mesoporous materials formed by liquid crystal templating. In the first part, we describe a geometric model with which the lattice parameters of different liquid crystal mesophases can be predicted as a function of their water/surfactant/oil volume fractions, based on certain geometric parameters relating ...

Heteroepitaxy of semiconductors on two-dimensional (2-d) atomic layered materials enables the use of flexible and transferable inorganic electronic and optoelectronic devices in various applications. Herein, we report the shapeand morphology-controlled van der Waals (vdW) epitaxy of ZnO nanostructures on hexagonal boron nitride (hBN) insulating layers for an architectured semiconductor integrat...

The copper doped ZnO (CuxZn1-xO, where x = 0, 0.01, 0.02, 0.04, 0.05) nanoflowers were produced by using co-precipitation process. Hexagonal wurtzite nanocrystalline phase of both pure and Cu-doped samples was confirmed X-ray diffraction analysis. Field emission scanning electron microscopy results the emergence fully dispersed nanoflower like morphologies in uniform dispersion particles. Band ...
