(Reward for high scores) please give a short article about the development direction of functional materials research (200-300 words) Introduction: mention the word 'nano,Many people may have heard of it,But what is nano,What is nano-material,It may not be clear to many people,This paper mainly introduces the research status and development prospects of nano-and nano-materials,I believe that with the development of science and technology,There will be more and more nano-materials coming into people's lives,For the benefit of mankind.Nano is the translation of English namometer,Is a unit of measure in physics,1 nano is one billion of 1 m;Equivalent to the length of 45 atoms arranged.Generally speaking,Equivalent to the thickness of one in ten hair.Like mm, Micron,Nano is a scale concept,There is no physical connotation.When the material reaches the nano scale,It's about 1-This range of 100 nm,The performance of the substance will change,Special performance appears.This one is different from the or
Water scale can be filtered through the water purifier? what brand is good? This depends on the type of water purifier you choose. To solve the problem of direct drinking and removing scale, you can choose the RO membrane pure water machine. the filtration accuracy of this type of water purifier is 0.001 microns, pure physical filtration, and the salt removal rate is as high as 90%, it can effectively remove the scale and reduce the water hardness value below the standard range. Another type of machine can use a soft water machine to remove scale. This type of machine uses a softening resin for ion exchange to remove scale, which belongs to chemical scale removal, the softened water is suitable for living water such as bathing and washing clothes. Both the pure water machine and the soft water machine can remove the scale, but the water purifier using the ultra-filtration membrane cannot remove the scale, because the filtration accuracy of the ultra-filtration membrane water purifier is 0.01 microns, it can't
