MIT Develops Nanocrystals to Detect Counterfeit Products
 |
Now, falsification has become a fairly large-scale industry. The Organization for Economic Co-operation and Development (OECD) speculated in 2009 that the counterfeiting industry at that time created a total of US$250 billion in illegal income. In recent years, the counterfeit industry has developed at an extremely rapid rate, and the areas covered include all aspects, including even the olive oil and medicines that we consume daily.
In order to prevent the continued development of such bad conditions, MIT scientists have recently developed a micro-nano crystal that can detect counterfeit goods. According to reports, this nanocrystal is only 200 microns in length. Researchers use rare earth minerals in the crystals. They have a very unique polymer flow pattern that exactly recognizes the legitimacy of a product, but it requires a database of safety labels to operate properly.
The present invention provides a multifunctional pull faucet, comprising: a faucet body, a drawing part is provided at the water outlet port thereof, and the drawing part is connected to a main channel, wherein at least three are provided in the faucet body A branch channel, and the three branch channels are all connected to the main channel. A multifunctional pull faucet provided by the present invention, wherein the hot water channel, the cold water channel and the water purification channel (pure water channel) are all connected to the main channel , And the main channel is connected with the drawing part on the main body of the faucet, so that the drawing part can obtain the water quality (hot water, cold water, purified water or pure water) required by different users, thereby improving the user experience, and , By integrating the hot water channel, cold water channel and pure water channel (pure water channel) into the main channel, the internal structure of the faucet is simplified, and the production cost of the faucet is reduced.
