The morphology of ZnO powders was investigated using field-emission scanning electron microscopy (FE-SEM), using a Carl Zeiss Sigma microscope equipped with a Schottky field emitter (tip made of <100> tungsten crystal and a ZrO₂ reservoir). Additionally, a scanning electron microscope (SEM Zeiss Evo 50 XVP with LaB₆ source) was employed for analyzing the surface and the cross-section of the composite films. SEM analysis was also employed for the observation of the laser cut exploited for preparing cantilevers to be used in the piezoelectric tests. For cross-section observation, the samples were fractured in liquid nitrogen. Backscattered electrons were employed for surface analysis. All the films were gold-metalized using an E5 150 SEM coating unit.

The TEM analysis was performed using a Jeol TEM-1011 microscope, provided with an Olympus Quemesa Camera (11 Mpx, Olympus, Tokyo, Japan). The samples were prepared by depositing on a carbon-coated Cu grid (400 mesh) a drop (5 μL) of C-dots or the micellar nanostructure solution. For sample staining, the grid was placed on the top of a drop of an aqueous phosphotungstic acid solution 2% (w/v) for 30 s, after the evaporation solvent. Then, the grid was washed with ultrapure water and left to dry. A statistical size analysis was performed on the C-dots samples using the Image J 1.53e analysis program.
Field emission scanning electron microscopy (FE-SEM) was performed using a Zeiss (Oberkochen, Germany) Sigma microscope operating in the range of 0.5–20 kV and equipped with an in-lens secondary electron detector and an INCA energy-dispersive spectroscopy (EDS) detector. The HA spray-dried samples were mounted onto stainless steel sample holders using double-sided carbon tape and grounded by silver paste.

SEM (scanning electron microscopy) and cryo-SEM images are acquired using a Zeiss Sigma microscope. All the gel samples were first dried in vacuum for 2 days prior to SEM experiments. Cryo-SEM was done using samples as they were. TEM (transmission electron microscopy) images are taken with a JEOL JEM 2010 electron microscope.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
