Transmission electron micrographs of a multilayer film consisting of 360 alternating layers of plasma deposited hydrogenated amorphous silicon and silicon nitride show that each 28-Å-thick layer is remarkably flat and uniform. Within the first 1000 Å near the glass substrate the regular growth of the layers is disturbed by instabilities which resemble dislocations in the layering. Electron microscopy of compositional layering may prove to be an important tool for studying the growth mechanism during plasma deposition. [ABSTRACT FROM AUTHOR]

Abstract: Gold nanoparticles supported on carbon nanotubes (CNTs) were obtained by using electroless plating technique. High-resolution transmission electron microscopy evidenced the high-density and homogeneous dispersion of spherical gold nanoparticles on the outer surfaces of the carbon nanotubes, with a sharp particle size distribution centered at around 3–4 nm of diameter. The resultant hybrid nanostructures have potential application for being used as novel gold nanocatalysts. [Copyright &y& Elsevier]

Abstract: Pure copper nanocrystallites and cuprous oxide nanorods have been synthesized via solvothermal treatment of CuSO4 or CuSO4·5H2O and NaOH in pure ethanol and mixed solution of ethanol and deionized water at 140 °C for 10 h, respectively. Transmission electron microscopy (TEM) and high-resolution transmission electron microscopy (HRTEM) were used to investigate the different morphologies of the as-synthesized products. X-ray powder diffraction (XRD) and selected area electron diffraction (SAED) were applied to characterize the composition and crystal phases of the products. It was proposed that the reducibility of ethanol was influenced by temperature and the addition of deionized water in the formation of different phases, which were realized by carefully controlling the experimental conditions.

Abstract: Gold nanoparticles supported on carbon nanotubes were prepared by using electroless plating technique. High-resolution transmission electron microscopy (HRTEM) has shown that spherical gold nanoparticles were homogeneously dispersed on the surfaces of the carbon nanotubes with a distribution of particle sizes sharply at around 3–4nm in diameter. The results presented in this work will probably provide new catalysts with better performances. [Copyright &y& Elsevier]

Cobalt-filled carbon nanotubes were prepared in situ in the decomposition of benzene over Co/silica-gel catalysts. Unlike the previous reports, in our experiments, the catalysts need not pre-reduced. Transmission electron microscopy (TEM) investigation showed that the as-made products contained abundance of carbon nanotubes (CNTs) and almost 100% of them were filled with metallic nanoparticles or nanorods. High-resolution TEM (HRTEM), selected area electron diffraction (SAED) patterns and energy dispersive X-ray spectroscopy (EDS) confirmed the presence of Co inside the nanotubes. The encapsulated Co was further identified as alpha-Co with face-centered cubic (fcc) structure, which frequently consists of twinned boundaries. Based on the experimental results, a possible growth mechanism of the Co-filled nanotubes was proposed. [Copyright &y& Elsevier]
