Reparing Liver Damage
Scientists in Taiwan recently discovered that the placement of gold nanoparticles inside the leaves of the trees makes them emit a bright red glow. The idea of using trees to replace street lights is very clever - you not only save on electricity costs and reduce CO2 emissions, but could also greatly reduce light pollution in major cities. The discovery came as scientists by accident after looking for a way to create a similar high-efficiency lighting to LED technology, but without using toxic chemicals such as phosphor powder. Talking about the course, Professor Shih-Hui Chang said: "The light emitting diode (LED) has replaced the traditional light source on many screens and street lighting on roads. A lot of light emitting diodes, LEDs white light emitting mainly used to stimulate phosphor powder light of different wavelengths. However, the phosphor powder is highly toxic and its price is high. As a result, Dr. Yen-Hsun Wu had the idea try to find a method that is less toxic and could replace the phosphor powder. "
