Recent scientific advancements have opened new opportunities for the close observation of physical phenomena. Researchers at University of Cambridge and University of Newcastle recently introduced a ...

One big dream of ultrafast science has been to watch changes in nanoparticles or biomolecules on their natural timescale.

Coherent X-ray Diffraction patterns of collagen in soft tissues have been measured for the first time by Dr Felisa Berenguer at the London Centre for Nanotechnology with her colleagues. This ...

A new method separates overlapping X-ray snapshots taken femtoseconds apart, opening a way to watch individual nanoparticles ...

Turning diffraction into a tool The technique uses a device that can only turn pixels on and off. Conventional thinking suggests that such a system can create only two levels of light intensity. The ...

When a laser beam is incident on many small objects such as lycopodium powder, the resulting diffraction pattern is similar to the diffraction pattern of a small circular aperture (Airy's disk pattern ...

Diffraction gratings separate different wavelengths of light using a periodic pattern embedded in the grating. The diffraction pattern can affect the amplitude and/or phase of the incident light as ...
