Quantum physics overturned classical ideas by showing that matter behaves very differently at the smallest scales. One of its most surprising discoveries was wave-particle duality, the idea that ...

First experimental observation of matter-wave diffraction in a short-lived electron-positron atom using a graphene-based diffraction grating. (Nanowerk News) One of the discoveries that fundamentally ...

Twenty years ago, consumers went to Amazon to buy their books, Facebook to find their friends and YouTube to watch silly videos. Today, all three companies — and plenty of newer rivals — compete ...

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 ...

Is it possible to 3d print a diffraction pattern? People in Denmark 'stunned' by Trump's Greenland comments, former ambassador says Tenacious D's Kyle Gass addresses controversial Trump joke and Jack ...

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 ...

Abstract: The concept of metagratings has been proposed as an efficient method of controlling the diffraction field of electromagnetic waves. In this paper, a reflective metagrating with ...

Carbon fiber is a critical material in a wide range of industries, where it is highly valued for its high specific strength/stiffness, excellent wear resistance, efficient electrical and thermal ...

UHRL, San Jose, CA, USA. Likewise, periodic Bragg diffraction can be interpreted in more than one way to include quantization; but our dual diffraction, that is partly (linear) Bragg diffraction and ...
