Atom-probe tomography (APT) is a quantitative technique that permits three-dimensional (3-D) spectroscopic characterization of interfaces and other nanometer-scale features within a material. Specimens for atom-probe tomography (APT) analysis of semiconductor devices and nanostructured materials are typically fabricated employing a focused ion beam (FIB) instrument [1 3] or a dual-beam FIB inst...

The first Korean cold room facility for ice mechanics experiments was assembled in 2004. Since then, the 4 m x 6 m cold room facility has been extensively used under various different environmental and loading conditions. After reviewing published references on cold room testing methods and also by trial and error, the standard procedures for testing and preparing laboratory ice material were e...

This protocol describes the preparation of mouse embryos for ultramicroscopy (UM), a powerful imaging technique that achieves precise and accurate three-dimensional (3D) reconstructions of intact macroscopic specimens with micrometer resolution. In UM, a specimen in the size range of ∼1-15 mm is illuminated perpendicular to the observation pathway by two thin counterpropagating sheets of laser ...
