Transmission
electron microscopy (TEM) and angular dark-field scanning transmission
electron microscopy (STEM) were used to analyze the structure of the
NCs on a JEOL JEM-2011F that was run at an accelerating voltage of
200 kV and mounted with a Gatan camera. Prior to imaging, samples
were drop-casted on a nickel TEM grid. Using ImageJ software and counting
>100 particles per sample, size statistics were calculated. On
an
FEI Titan Cubed Themis G2 300, aberration-corrected microscopy, high-resolution
TEM (HRTEM) imaging, high-angle annular dark-field STEM (HAADF-STEM)
imaging, and energy-dispersive X-ray spectroscopy (EDX) with elemental
mapping were carried out.

Characterization of Carbonaceous Porous Dielectric

The microstructures of the CPD were investigated via HRTEM and SAED using a transmission electron microscope (JEM-2011F, JEOL Ltd., Japan) with an accelerating voltage of 200 kV. To depict the distribution of the amorphous carbon zone and graphite fragments zone in CPD, we performed pseudo-color calibration of the phase regions of multiple HRTEM images. Then ImageJ was employed to quantitatively analyze the corresponding areas, ultimately determining the content of each phase. The stress field of the nanocomposite phase structure was characterized via geometric phase analysis using the background-filtered image in Strain + + software. The component phases and structure of the CPD were characterized via TEM, XRD (Smartlab, Rigaku, Japan) with CuK_α radiation (I = 1.541838 Å), XPS (PHI 5802, PHI, USA), and Raman spectroscopy (alpha300 R, WITec, Germany) with an excitation wavelength of 532 nm. Prior to XPS measurement, a 0.5 nm-thick Au coating was sputtered onto the samples to calibrate all spectra by shifting the Au 4f-7 peak to 84.0 eV.

To compare the concentration of dispersed solutions, their UV absorption were characterized by UV–Vis spectrophotometer (Agilent Technologies lnc., Agilent 89090A). The zeta potential of dispersed solution was investigated by Zetasizer (Malvern Instruments Ltd., Nano-ZS90). The chemical state of the Nb₂Se₉ was examined by XPS (Thermo, ESCALAB250). The samples for XPS were prepared by vacuum filtration method on the AAO membrane with a pore diameter of 100 nm. The morphologies of the exfoliated nanowires were analyzed by atomic force microscopy (Park Systems, NX 10) and aberration-corrected scanning transmission electron microscopy (STEM, JEOL, JEM-2011F). The AFM was operated in non-contact mode, and the samples for AFM were prepared on SiO₂/Si wafers by spin-coating. The samples for STEM were prepared by drop-casting onto a carbon-coated TEM grid^{35 (link)}.

The morphologies of the as-synthesized materials were characterized by a transmission electron microscope (TEM) equipped with energy-dispersive X-ray spectroscopy (EDX). High-resolution transmission electron microscope (HR-TEM) and selected area electron diffraction (SAED) were performed on the field emission-transmission electron microscope (FE-TEM, JEOL JEM-2011F).
The crystal planes of the as-synthesized materials were identified by powder X-ray diffraction (XRD) using Rigaku SmartLab with a CuKα (λ = 1.541862 Å) radiation, operating at 45 kV and 200 mA, with a scanning rate of 0.05°/s and 2-theta ranging from 20° to 90°.
X-ray photoelectron spectroscopy (XPS) studies were also carried out using Axis Ultra DLD XPS system equipped with monochromatic Al−Kα radiation of 1486.6 eV and an electron take-off angle of 90°. The pressure of the sample chamber was kept at 10⁻⁸ Torr during analysis. The spectrum was recorded in the binmr1ding energy (B.E.) range of 0.00 to 1400.00 eV with a step size of 1.00 eV. The binding energy was referenced with the C 1s peak of the carbon at 285.0 eV.
The mass loading on the carbon nanotubes supporting samples was measured by induced coupled plasma mass spectrometry (ICP-MS).

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.
