A pattern of distorted lines is visible as a reflection in this close-up view of a human eye. By observing the deformation of ...

Several approaches are capable of beating the classical 'diffraction limit'. In the optical domain, not only are superlenses a promising choice: concepts such as super-oscillations could provide ...

This new method describes an experimental concept called ultrafast vortex electron diffraction, which allows for direct ...

Quasicrystals are intriguing materials with long-range atomic order that lack periodicity. It has been a longstanding ...

Description: Electron diffraction patterns for single crystal and polycrystalline materials are displayed on a CRT screen. A Welch model 2639 'Electron Diffraction tube' is used in an experiment in ...

It discusses various methods for studying minerals, including polarized light microscopy and x-ray diffraction to identify mineral structures. The film also covers the formation of different types ...

Conventional curved lenses, which direct light by refraction in glass or plastic, are often bulky and heavy, offering only ...

What is the Diffraction Limit? The diffraction limit is a fundamental barrier in optical microscopy that sets the minimum size of features that can be resolved using conventional light microscopes. It ...

The Materials Research X-Ray Diffraction (XRD) Facility at the University of Colorado Boulder provides cutting-edge capabilities for probing the structures of materials such as polymers, biological ...

Researchers at the Fraunhofer Institute for Applied Optics and Precision Engineering (IOF) say that they have built a thulium fiber laser capable of emitting 1.91 kW - nearly double the typical output ...

"This award is a part of the Department of Energy’s Funding for Accelerated, Inclusive Research (FAIR) program, which is focused on building research capacity at academic institutions, like Alabama ...

The emergence of imaging schemes capable of overcoming Abbe's diffraction barrier is revolutionizing optical microscopy. In 1873, the German physicist Ernst Abbe realized that the resolution of ...
