Microscopy represents a fundamental method for cultural heritage materials research and it is essential for paintings cross-sections investigation. Because of the smallness of sample, microscopy and micro-spectroscopy analysis techniques have taken a leading role in the past decades, improving and expanding research possibilities. The increasing accuracy and versatility of the instrumentation enable immediate and precise results. Furthermore, the combination of different non-destructive micro-analytical techniques, allows a more complete characterization of the sample.

A new calibration approach allows a fast and easy-to-handle geometric calibration of Scanning Electron Microscopy (SEM). This article outlines the application of 3D calibration standards with spatially distributed circular reference markers. The underlying marker-based calibration concept determines scale and shear factors of the coordinate axes and facilitates the analysis of image distortions and other remaining image errors. We present the application of 3D calibration standards, both for 2D and for 3D measurements, and show its contribution to achieving a higher measurement accuracy.

The conference "Microscopy of Semiconducting Materials" will take place from March 29 - April 2, 2015 at the Murray Edwards College in Cambridge, UK. This bi-annual conference series has a long tradition in focusing on the most recent advances in the study of the structural and electronic properties of semiconducting materials by the application of transmission and scanning electron microscopy.

Microscopes don't exactly lie, but their limitations affect the truths they can tell. For example, scanning electron microscopes (SEMs) simply can't see materials that don't conduct electricity very well, and their high energies can actually damage some types of samples. In an effort to extract a little more truth from the world of nanomaterials and nanostructures, researchers at the National Institute of Standards and Technology (NIST) have built the first low-energy focused ion beam (FIB) microscope that uses a lithium ion source.

PML researchers have devised an idea for determining the three-dimensional shape of features as small as 10 nanometers wide. The model-based method compares data from scanning electron microscope (SEM) images with stored entries in a library of three dimensional (3D) shapes to find a match and to determine the shape of the sample. The work provides a powerful new way to characterize nanostructures.

The macro- and microstructure of iron meteorites provide valuable insights into both the inner structure of our planet and the history of our solar system. High speed collision events in the asteroid belt send the meteorites careening toward Earth. The collisions produce unique deformation microstructures. With cooling rates on the scale of a few degrees per million years, iron meteorites can consist of crystal sizes on the order of meters prior to the collision events. These extremely slow cooling rates result in phase transformations occurring at conditions near thermodynamic equilibrium. Preserving meteorite fragments is important for future studies of phase transformations, material behavior at high strain rates, and the origin of the universe.
