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 ...

One of the discoveries that fundamentally distinguished the emerging field of quantum physics from classical physics was the observation that matter behaves differently at the smallest scales. A key ...

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 ...

Abstract: X-ray ptychography is a lensless imaging technology with promising applications that can achieve nanometer resolution. However, the noise in the diffraction patterns degrades the performance ...

LONDON, May 7 (Reuters) - Alpine have gone from having the youngest principal in the Formula One paddock to the oldest, while handing Pierre Gasly a third different teammate in nine races -- all in ...

McLaren Racing today announces that following a strategic review of its racing portfolio the decision was taken not to continue our participation in the FIA Formula E World Championship beyond the ...
