Researchers show light can add drag to fluorescent carbon nanotubes in water, revealing quantum friction that may help ...

Most people probably don’t think of everyday activities – such as hanging out the washing or putting away the groceries – as having an effect on their long-term health. But new research suggests that ...

A new atom camera uses one ultracold rubidium atom to map light intensity and polarization with spatial resolution below 100 nanometers.

The light intensity curves for LEDs, regardless of whether they are collimated with a lens or reflectors, follow a bell shaped curve (often referred to as a “Lambertian“ curve). The 50% intensity ...
