This 'cooling glass' is more than a new material – it's a key part of the solution to climate change,” he said. “By cutting down on air conditioning use, we're taking big steps toward using less energy and reducing our carbon footprint. It shows how new technology can help us build a cooler, greener world." Apart from lens material, choosing the right lens color is also very important. From gray and green to brown, yellow, red and amber, different lens colors add to the performance of your lenses in different light conditions and offer different kinds of protection or vision enhancements.

The team used finely ground glass particles as a binder, allowing them to avoid polymers and enhance its long-term durability outdoors, Zhao said. They chose the particle size to maximise emission of infrared heat while simultaneously reflecting sunlight.

Finding new, more energy-efficient alternatives to traditional air conditioning systems could stand to make a significant dent in global emissions. The new technology, a microporous glass coating described in a paper published in the journal Science, can lower the temperature of the material beneath it by 3.5 degrees Celsius at noon, and has the potential to reduce a mid-rise apartment building's yearly carbon emissions by 10%, according to the research team led by Distinguished University Professor Liangbing Hu in the Department of Materials Science and Engineering.Wine goblet, blue glass decorated with white and gold enamel, Iran, mid-19th century; in the Brooklyn Museum, New York. (more) According to the new research paper, the resultant microporous glass coating can lower the temperature of materials beneath it by up to 3.5 °C at noon. Additional calculations show that the use of this material in a standard mid-rise apartment building could potentially reduce that building’s annual carbon emissions by 10%. Triangular faces have narrow foreheads and broad jawlines with square or flat chins. Aviators, clubmasters, teardrops, and rectangular sunglasses are the best sunglasses for men with triangular face.
