The current detergents are very advanced, but some stains are still difficult to remove at lower temperatures. For this reason, people often use hot water of 60 to 90 degrees Celsius for laundry, which is not only cumbersome but also extra energy.
British researchers in the latest "Applied Materials and Interface" magazine report that nano-diamonds, which are less than one ten-thousandths in size, can help loosen the stains attached to the surface of clothing materials, adding a small amount Nano-diamonds can improve the performance of detergents and remove stubborn stains at room temperature and even at low temperatures.
Research leader Andrew Marsh said on the 26th that if you add a small amount of about 5 nanometer-sized diamond particles, you can double the performance of a common detergent on the market at 25 degrees Celsius. Even at lower temperatures of 15 degrees Celsius, nano-diamond-added detergents can make some normally difficult-to-remove stains more soluble in water.
Nano-diamonds sound expensive, but researchers say nano-diamonds are currently priced at about 30 pounds per gram (a pound is about 9.87 yuan), which could drop below 5 pounds if put into large-scale markets. Researchers believe that in the future, if consumers use nano-diamond detergents, the cost of each laundry will only increase by about 5 pence (1 pound is equal to 100 pence), but it can make cryogenic laundry more effective.
