Recreating the double-slit experiment that proved the wave nature of light in time, instead of space

Imperial physicists have recreated the famous double-slit experiment, which showed light behaving as particles and a wave, in time rather than space.

Scientists demonstrate time reflection of electromagnetic waves

When we look in a mirror, we are used to seeing our faces looking back at us. The reflected images are produced by electromagnetic light waves bouncing off of the mirrored surface, creating the common phenomenon called spatial ...

Fluid mixing enables scalable manufacturing of soft polymer structures

Researchers have developed and demonstrated an efficient and scalable technique that allows them to manufacture soft polymer materials in a dozen different structures, or "morphologies," from ribbons and nanoscale sheets ...

Perovskites, a 'dirt cheap' alternative to silicon, just got a lot more efficient

Silicon, the standard semiconducting material used in a host of applications—computer central processing units (CPUs), semiconductor chips, detectors, and solar cells—is an abundant, naturally occurring material. However, ...
