Comprehensive Microscopy Analysis of Au/Ag Nanoclusters on Silica Nanospheres

Qian H., Shen W., Cui K., Cho J., Fenniri H., National Institute for Nanotechnology, CA

we report a comprehensive structural and morphological analysis of gold (Au) / silver (Ag) nanocluster (shell) on silica (SiO2) nanosphere (core) with transmission electron microscopy (TEM) based techniques, including scanning transmission electron microscopy (STEM) tomography, [...]

Advanced CryoTEM and Tomography for Two- and Three-Dimensional Nano-Characterisation of Soft Matter

Sourty E., de Haas F., Frederik P.M., Frederik P.M., Loos J., Stokes D.J., Hubert D.H.W., FEI Company, NL

Recent advances in transmission electron microscopy (TEM) mean that we are able to achieve unprecedented resolution at the atomic level. Furthermore, improved methods for obtaining and reconstructing tilt series projections allow us to create high [...]

Advanced Particle Beam Technologies for Nano-Characterization and Fabrication

Mulders J.J.L., Greiser J., FEI Company, NL

As the structures under investigation grow ever smaller, the need for high resolution, nanoscale imaging and protoyping is a constant factor. The presented range of DualBeam and single column focused ion and electron beam microscopes [...]

Conical Tomograph: A Method for the Study of Macromolecular Assemblies

Zampighi G.A., Zampighi L., Fain N., Lanvazecchia S., Zampighi G.A., Zampighi L., University of California, Los Angeles School of Medicine, US

We have developed conical tomography to study the structure of macromolecular assemblies and organelles in their native cellular environment. Unlike the other related types of tomography, conical tomography has a higher throughput and more importantly, [...]
