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 ...

For over 100 years, quantum physics has taught us that light is both a wave and a particle. Now, researchers at the Massachusetts Institute of Technology (MIT) have performed a daring experiment using ...

Crystallography is the science of analyzing the pattern produced by shining an X-ray beam through a material sample. A powder sample produces a different pattern than solid crystal. One longstanding ...

Changing light's polarization can reverse the structure of a patterned light field, opening a new way to control geometry and information in optics. (Nanowerk Spotlight) Light can be bent, focused, or ...
