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 ...

Nonlinear interactions between light and matter are at the heart of some of the most powerful tools in modern optics, but pushing these processes to their limits has long been hampered by a ...

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 ...
