A mechanical blue LED: Stretching GaN shifts light from UV to blue without changing chemistry
A research team from the Faculty of Engineering at the University of Hong Kong (HKU) has successfully used mechanical ...
Researchers have designed and tested ‘human-centric’ LEDs that emit different wavelengths of blue light depending on whether it’s daytime or nighttime, reducing the disruptive effect artificial light ...
Several pieces of evidence have suggested that blue light can inactivate various pathogenic bacteria. Previously in vitro and in vivo studies using blue light in the spectral range of 400–470 nm ...
UVB has utility in processes such as detoxifying pollutants and treating dermatological disorders, but it can only be produced by inefficient and environmentally harmful methods. Research teams have ...
We all have that favorite piece of clothing, and we're all familiar with the sinking feeling when we spill something on it. But now, new reports have revealed a simple way to remove pesky stains. ACS ...
You may know them by the acronym ROY G BIV. Together, they make the white light you see when the sun -- the main source of blue light-- is shining. Fluorescent and LED (light-emitting diode) light ...
