What are the four major effects of nano-materials and their practical meanings? 10 1. surface effect refers to the change in properties caused by the sharp increase of the ratio of nano-particle surface atoms to total atomic numbers with the smaller particle size.Table 9-2 The relationship between the size of nanoparticles and the number of atoms on the surface is given.With the decrease of particle size,The number of atoms on the surface increases rapidly.In addition,With the reduction of particle size,The surface area and surface energy of nanoparticles are rapidly increasing.This is mainly the smaller the particle size,The more atoms are on the surface.The crystal field environment and binding energy of surface atoms are different from those of internal atoms.There is a lack of adjacent atoms around the surface atoms,There are many dangling keys,With unsaturated properties,It's easy for other atoms to settle down if they want to combine,Therefore, it shows great
Does installing the filter affect the pressure of the water? Affected, there is a certain pressure difference between the water passing through the filter. Otherwise there is no filtering effect.
