Is it possible to 3d print a diffraction pattern? Super Typhoon Fung-wong devastates the Philippines Celebrities who have cut ties with family members Dog's guilty face after owner finds broken toy ...

The original version of this story appeared in Quanta Magazine. Since their discovery in 1982, exotic materials known as quasicrystals have bedeviled physicists and chemists. Their atoms arrange ...

Optical dispersion occurs when the refractive index of a material changes with the wavelength of incoming light. This variation causes different colors to move at different speeds in transparent media ...

Since their discovery in 1982, exotic materials known as quasicrystals have bedeviled physicists and chemists. Their atoms arrange themselves into chains of pentagons, decagons and other shapes to ...

One of the simplest and most beautiful naturally occurring patterns can be observed when light is shined through a pair of slightly misaligned periodic structures. This phenomenon, known as the moiré ...

A unique propagation phenomenon of acoustic waves has been discovered, paving the way for developing advanced communication technologies using acoustic devices. The research, published in Physical ...

Scientists have observed “bending” atoms using a crystal grating—an experiment once believed impossible at the high energies required. The authors of a new, non-peer reviewed study detail how the a ...

Scientists have demonstrated that atoms can exhibit wave-like behavior, challenging long-held assumptions that experiments of this nature were impossible and opening new doors in quantum physics. The ...

XRD works by directing X-rays onto a crystalline material and analyzing the angles and intensities of the diffracted beams. The atomic planes within the crystal act as a three-dimensional grating, ...
