With the development of different techniques for the synthesis of nanomaterials, researchers are constantly looking for a more precise instrument for their nanoscale characterization. X-ray ...

Reconstructing the phase of a field from intensity measurements is an old and ubiquitous challenge, known as the phase retrieval problem 1,2,3. It has found numerous applications spanning from ...

A pulse of light sets the tempo in the material. Atoms in a crystalline sheet just a few atoms thick begin to move—not randomly, but in a coordinated rhythm, twisting and untwisting in sync like ...

X-ray techniques have been used for decades by authorities to prevent crime and keep people safe. Perhaps their most well-known use is for the detection of dangerous and banned items or substances, ...

Diffraction-based analytical methods are widely used in laboratories, but they struggle to study samples that are smaller than a micrometer in size. Researchers have nevertheless been successful in ...

X-ray crystallography, like mass spectroscopy and nuclear spectroscopy, is an extremely useful material characterization technique that is unfortunately hard for amateurs to perform. The physical ...

The diffraction grating of a spectrometer partially determines the optical resolution that can be achieved by the spectrometer and also determines the wavelength range. Selecting the correct grating ...

Test for echo: schematic diagram of an object to be imaged (blue blob) and illumination source (concentric circles) inside a randomly shaped cavity. The detector is represented by the two parallel ...

Non-ambient diffraction is a powerful tool for identifying the effects of temperature, humidity, pressure, or atmosphere on a sample. Materials exposed to non-ambient environments tend to have ...
