Ultrafast electron imaging reveals never-before-seen nuclear motions in hydrocarbon molecules triggered by light. The ...

In a new paper, Jordan Jensen and Alexis Ault introduce a new forensic tool designed to enhance our understanding of how ...

Researchers from the University of Science and Technology of China (USTC) have unveiled a planar optical device that significantly enhances the capabilities of dark-field microscopy, achieving ...

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 ...

This new method describes an experimental concept called ultrafast vortex electron diffraction, which allows for direct visualization of electron movement in molecules on attosecond timescales.

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 ...

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

BEIJING — It's highly technical work in what looks more like a lab than a museum: A fragment of a glazed roof tile from ...

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 ...

Students will be able to perform standard x-ray diffraction measurements on metals, ceramics and polymers and quantitatively interpret the results. Students will attain an intermediate level 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 ...
