Quantitative Analysis of Oxidation State in Cerium Oxide Nanomaterials

Gorham J.M., Hackley V.A., Johnston-Peck A.C., Maier R.A., Nelson B.C., Sims C.M., National Institute of Standards and Technology, US

Of the many engineered nanomaterials being incorporated into our society, cerium oxide (ceria, CeO2-x) based nanomaterials (NMs) are receiving increased attention due to their unique chemical properties and vast number of current and potential applications [...]

Analytical Transmission Electron Microscopy characterization of nano-structured materials

Sharma U., Susnitzky D., Evans Analytical Group, US

This article reviews applications of analytical transmission electron microscopy (TEM) to characterize nano-structured materials and devices. Several practical examples are provided that show the diverse imaging and microanalysis mechanisms available in a modern TEM. By [...]

Image-based Nanocrystallography in Two and Three Dimensions with

Bjorge R., Fraundorf P., Moeck P., Portland State University, US

It is well known that many nanocrystals can not be identified from their powder X-ray diffraction pattern as it is customary for collections of micrometer sized crystals. The crystallographic phase and shape of nanocrystals can, [...]

Characterisation of Native-State Soft Matter using ‘Multi-Mode’ Electron Microscopy

Baken E., Hubert D.H.W., Lich B.H., Stokes D.J., FEI Company, NL

Soft condensed matter and complex fluids are of increasing technological significance. It is therefore crucial that we extend the capabilities of conventional solid state imaging and analytical techniques to include the observation of materials such [...]
