Iranian Company Uses Nanotechnology to Make Hydrophobic Outdoor Light Bulb
‘Gollnoor’ company has made the product which is a light bulb whose external surface is chemically modified to show a hydrophobic property. This feature has made the bulb self-cleaning with no pollutant able to settle down on it.
The creation of micrometric and nanoscale roughness on the external surface of the light bulb through functionalization has led to emergence of hydrophobic property on the external surface of the light bulb, considerable changes in chemical and physical interactions between the superficial areas and settling pollutants.
The hydrophobic light bulbs can be used in outdoor places and regions with a high level of air pollution.
Earlier this year, a technological company in Iran had also developed a special device for the disposal of mercury vapors from the wastes of fluorescent, energy-saving and gas lamps.
The company has designed an Iran-made device that crushes energy-saving, fluorescent and gas lamps before relocating them to a recycling center and controls all mercury vapors in these lamps.
The device is equipped with a 200-liter tank that can hold 300kg to 350kg of lamp waste.
Mercury particles and vapors are controlled and removed by the filters installed in the device during the crushing process, removing all concerns about the broken lamps during storage, handling and transportation.
