It is one of the easiest and most rewarding benefits of modern life to turn on a light whenever you want. Traditionally, this was done by heating the wires in the bulb to give them bright white light. Now, researchers have come up with a more direct approach by inventing a new material that converts photons from infrared lasers into visible light.
The laser emits light to a transparent molecular film containing tin and sulfur atoms, where the atoms are arranged in a diamond-like pattern and surrounded by organic groups. The molecules in the film absorb the photons of the infrared laser and re-release the energy in the form of higher-energy visible photons. Most molecules will reappear like a pile of coins being replaced with brand new notes, a process that uses less energy from visible infrared photons from the energy of many infrared laser photons.
This conversion is not new. What's new is that tin and sulfur films direct the light to form a single beam. Researchers reported the result in a recent issue of Science. While most older conversion materials randomly send visible photons in different directions, the new technology can send it out in the same direction that light comes in. This gives it the ability to direct the beam to a specific place, making the material useful in microscopes and new projection systems.
The mite removal instrument (also known as the mite removal machine) The general mite removal instrument on the market adopts the function of beating + vacuuming + ultraviolet light to remove mites and sterilize, and some of them have the effect of hot air.
One of the most important functions, that is, the key to removing mites, is the flapping function. Beating cannot avoid the problem of amplitude, that is, the strength of vibration. To destroy the grasping power of the legs of mites, you need to choose a powerful and effective mite removal device. Moreover, the harm caused by mites to the human body does not only depend on itself, but also on the corpses and excrement of mites. Simply killing mites cannot be called a mite removal instrument. It is also necessary to vacuum out the mites and allergens.
