The ability to convert wavelengths of light is a crucial requirement in the improvement of many imaging, sensing and communication technologies. Endoscopy probes are just one example where this ...

Researchers have designed a new chip-integrated light source that can transform infrared wavelengths into visible wavelengths, which have been difficult to produce with technology based on silicon ...

1. Photons can produce shock waves in water or air, similar to sonic booms. Nothing can travel faster than the speed of light in a vacuum. However, light slows down in air, water, glass and other ...

A novel dye-sensitized photocatalyst developed at Science Tokyo enables the capture of long-wavelength visible light for efficient hydrogen conversion, surpassing conventional photocatalysts.
