Scientists have demonstrated a sort of holographic strip that splits a single laser beam into five bespoke beams that create an optical knot. The work shows that optical knots could be used as a ...

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 ...

The interior of the vacuum chamber during a scattering experiment. The detector is shown in grey (top right) and the Au(111) gold surface is shown in yellow. The lines indicate the path of the ...

A scalable nanofabrication method uses electric-field alignment and picosecond laser welding to imprint patterned silver nanowire networks on polymer films. (Nanowerk News) A breakthrough development ...

Researchers have discovered brand new interference patterns in twisted two-dimensional tungsten ditelluride lattices. These so-called moir patterns can be tuned to look like periodic spots or even one ...
