Cryo-SEM Observation of Coating Layer on Powder Surface

Cryo-SEM studies of latex/ceramic nanoparticle coating microstructure development.

Cryogenic scanning electron microscopy (cryo-SEM) was used to investigate microstructure development of composite coatings prepared from dispersions of antimony-doped tin oxide (ATO) nanoparticles (approximately 30 nm) or indium tin oxide (ITO) nanoparticles (approximately 40 nm) and latex particles (polydisperse, D(v): approximately 300 nm). Cryo-SEM images of ATO/latex dispersions as-frozen s...

Double layer coating for high resolution low temperature SEM

Specimen damage caused by mass loss due to electron beam irradiation is a major limitation in Low Temperature Scanning Electron Microscopy of bulk specimens. At high primary magnifications (e.g. 100 000 x) a hydrated sample is usually severely damaged after one slow scan (about 3000 enm-2). The consequences of this beam damage are remarkably reduced by coating the frozen-hydrated sample with a ...

Dip coating of silica layer on melt-spun Finemet ribbons: surface morphology and electrical resistivity changes

In this study, melt-spun Finemet ribbons were coated by a thin layer of SiO2 using dip coating method. Amorphous ribbon prepared by melt spinning method and dip coating were done by using a solution of tetraethylen orthosilicate as a SiO2 precursor, ethanol as solvent and distilled water for hydrolysis. Different thicknesses of SiO2 layer, namely 304, 349, 451, 526 and 970 nm were obtained prop...
