SEM tomography for the investigation of hybrid structures

The morphological investigation at the micrometric scale of a graphene - ZnO nanorods hybrid structure is performed by scanning electron microscopy. When operated in the scanning-transmission imaging mode, the detection strategy allows implementation of a tomographic approach to recover the three dimensional spatial arrangement of the sample constituents. This tomographic approach complements the serial-sectioning imaging methods and is suitable for thin, self-standing specimens

In-situ preparation of hybrid Ag-ZnO decorated graphene nanoplatelets

Ternary hybrid nanostructures of Ag-ZnO decorated GNPs have been prepared through a facile and simple one-pot hydrothermal method. FE-STEM analysis revealed that the Ag-ZnO nanostructures are crystalline and anchored onto the planar GNPs. XPS analysis also confirmed the successful preparation of high purity Ag-ZnO nanostructures onto GNPs. These versatile ternary hybrid nanostructures are expected to find their cost effective and multipurpose industrial applications

Synthesis and systematic structural characterization of highly crystalline ZnO nanorods

A cost effective method for the mass-production of high-purity ZnO nanorods (NRs) with uniform size distribution, based on the combination of thermal decomposition of zinc acetate dihydrate and probe sonication in acetone. The quality of the produced ZnO NRs, is assessed through various characterization techniques including field-emission scanning electron microscopy (FE-SEM), X-ray diffraction (XRD), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), and photo-luminescence spectroscopy (PL) and validated by comparison with ZnO microrods (MRs) and ZnO-nanoparticles (NPs)
