This series of papers deals with the description and visualization of mathematical functions used to describe a powder pattern. Accompanying each part is a collection of user-friendly, interactive and ...

Understanding the atomic-scale mechanism of crystallization is a fundamental issue in statistical mechanics and the basis for the synthesis of novel materials. We investigated the structures of single ...

For a circular aperture, interference occurs between all rays from the whole area producing a series of concentric fringes. The exact solution in this case is difficult but turns out to be of the same ...

Iron is the main constituent of the core of rocky planets; therefore, understanding its phase diagram under extreme conditions is fundamental to model the planets’ evolution. Using dynamic compression ...

We experimentally demonstrate planar lenses based on nanoscale slit arrays in a metallic film. Our lens structures consist of optically thick gold films with micron-size arrays of closely spaced, ...
