Feb 21, 2018 · In this report, we applied in situ transmission electron microscopy (TEM) to extensively characterise the thermal progressions of nickel-iron containing (Ni-Fe) LDH nanomaterials. The...

Nov 1, 2014 · The morphology and structure of the synthesized Ni nanoparticles were characterized by transmission electron microscopy (TEM), powder X-ray diffraction (XRD), QELS data and infrared spectroscopy (IR).

Feb 9, 2021 · In this study, microstructural changes, which relate to catalytic degradation for reforming hydrocarbons, in Ni nanocatalysts were observed in situ in oxygen, hydrogen, and methane atmospheres at elevated temperatures using an …

May 12, 2009 · Transmission electron microscopy (TEM) analysis was demonstrated nanoparticles Ni with an average diameter of about 14–22 nm. The products were characterized by X-ray diffraction (XRD), TEM, high-resolution transmission electron microscopy (HRTEM) and Fourier transform infrared (FT-IR) spectroscopy.

Nickel oxide (NiO) nanorings were synthesized by controllable thermal decomposition of precursor Ni (OH) (2) nanoplates obtained via the reaction between Ni (NO (3))·6H (2)O and NaOH under...

Electron irradiation of Ni–Fe layered double hydroxides (LDHs) was investigated in the transmission electron microscope (TEM). The initial structure possessed a flat hexagonal...

Nickel particles dispersed in an amorphous carbon matrix have been synthesized by a sonication method, and further heated at 773 K under Ar atmosphere. Both as-prepared and heated samples have been fully characterised using different techniques such as transmission electron microscopy (TEM), high resolution

Oct 6, 2013 · Herein, the crystallographic orientation relationship between Ni and YSZ in a practical cell was investigated by transmission electron microscopy (TEM), and scanning TEM (STEM). The TEM specimen was lifted out from bulk cell in a …

In this study, we actualized in situ growth of Co3O4 nanoneedles on titanium (Ti) mesh (denoted as Co3O4@Ti) by a simple combination of hydrothermal approach and subsequently calcination...
