Editor's note: According to foreign media reports, materials scientists at Kiel University in Germany and Hamburg University of Technology in Germany have recently developed the world's lightest material, which is called "aerographite".
This material weighs only 0.2 mg per cubic centimeter, which is 4 times lighter than the previous lightest material record creator, 6 times lighter than air, and 5000 times less dense than water. Aerographite is so light that it is difficult to use it to carry out research work in a normal laboratory. Any slight wind in the laboratory will blow it away. Researcher Matthias Mecklenburg said: "One kilogram of this material is 5 cubic meters in size, which means that it will occupy a 1 square meter base and a height of 5 meters, just like a A house or a tower. "
Aerographite is a network of carbon tubes with a diameter of about 15 nanometers. The material is made by placing zinc oxide crystals in a special oven and then heating them to 900 degrees Celsius. Due to its light weight and relatively large surface area, aerographite can be used to develop much lighter lithium-ion batteries, waterproof clothing, lighter computers, air purifiers, water purification equipment, and satellite shields.
Sunglasses can prevent ultraviolet rays from sunlight. Ultraviolet rays can damage the cornea and retina, and sunglasses can completely eliminate ultraviolet radiation. Sunglasses can prevent strong light. Light reflected from the sun will damage the retina. High quality sunglasses can filter up to 97% of the eye rays to avoid injury. Sunglasses can prevent glare. It can reflect large amounts of light, and the bright spots that it produces will disturb the line of sight or hide objects. Sunglasses can completely eliminate such glare with polarizing technology. There is also the role of beauty decoration. Sunglasses are an indispensable decoration for fashion.
