A U.K.-Portuguese research group is proposing a new solar cell design based on diffraction gratings – optical components that split and diffract light into several beams. They claim this could lead to ...

Fundamentals of electron diffraction -- Relation between crystal lattice, stereographic projection and reciprocal lattice -- Indexing polycrystalline and single-crystal patterns -- Orientation ...

A pattern of distorted lines is visible as a reflection in this close-up view of a human eye. By observing the deformation of illumination patterns reflected off the eye's surface, researchers in ...

Optics meets 2D materials: a simple probe light beam exiting an optical moiré lattice can be chopped up into diffuse streaks or confined into a single bright spot, depending on the twist angle in the ...

The basics of digital logic are pretty easy to master, and figuring out how the ones and zeroes flow through various kinds of gates is often an interesting exercise. Taking things down a level and ...

(Nanowerk News) Turning up the intensity of x-ray beams used to probe the atomic structures of materials can actually reduce the intensity of x-rays scattered from the material, a RIKEN-led team has ...
