In situ Study of Dynamics of CuAu Alloy Nanoparticles on Oxide Supports
نویسندگان
چکیده
The use of closed, electron transparent gas cells to perform in situ scanning/ transmission electron microscopy (S/TEM) now enables visualization of the atomic structure of catalysts at variable temperature in a gas environment, which may be close to real operational conditions [1]. When coupled with energy dispersive spectroscopy (EDS) detector, in situ composition analysis can be achieved at nm scale. Using this capability, here we demonstrate preliminary results from such an in situ study of the dynamics of CuAu alloy nanoparticles (NPs) supported on alumina and silica.

Radar absorption of FeNi nanoparticles and FeNi@PANI nanocomposites prepared by in-situ polymerization
In this research, FeNi@PANI nanocomposites as the electromagnetic wave absorbers were prepared through two following steps. At first, FeNi alloy nanoparticles were synthesized by the one-pot polyol process, and then, in-situ polymerization method was used for the preparation of FeNi@PANI nanocomposite. The XRD pattern confirmed the formation of pure FeNi alloy with the FCC crystalline phase. Th...

– A detailed numerical and experimental study of the ordering of the low-temperature tetragonal phase of CuAu is presented. The numerical simulations are based on a coarsegrained free energy derived from electronic structure calculations of CuAu, while the experimental results are obtained from in situ X-ray scattering. Both theoretical and experimental work indicate a subtle kinetic competitio...

Nanocrystalline particles of Cerium Oxide (CeO2) have been prepared by the chemical precipitation method using Cerium nitrate and Urea with a molar ratio of 1:2. The results revealed that the formation of CeO2 fine particles is influenced by molar ratio of metal nitrates to fuel. Well faceted CeO2 nanoparticles, were synthesized by thermal-assisted dissociation ...
