What are the parameters which change when your bulk material is converted into nanomaterials? Nanomaterials can occur naturally, be created as the by-products of combustion reactions, or be produced purposefully through engineering to perform a specialised function. The key difference between nanomaterials and bulk materials is that the nanomaterials have their size in 1-100 nm range at least in one dimension whereas the bulk materials have their size above 100 nm in all dimensions. This explains why different processing conditions can lead to different morphologies for the same material. Abstract. For example, nanozymes are substances that are nanoparticles, and they have enzyme-like characteristics. When the particle is small enough, however, the electrons are more constrained and become more like an electron confined to a small box. There are three major physical properties of nanoparticles, and all are interrelated: (1) they are highly mobile in the free state (e.g., in the absence of some other additional influence, a 10-nm-diameter nanosphere of silica has a sedimentation rate under gravity of 0.01 mm/day in water); (2) they have enormous specific surface areas (e.g., a standard teaspoon, or about 6 ml, of 10-nm-diameter silica nanospheres has more surface area than a dozen doubles-sized tennis courts; 20 percent of all the atoms in each nanosphere will be located at the surface); and (3) they may exhibit what are known as quantum effects. Under that definition a nano-object needs only one of its characteristic dimensions to be in the range 1100 nm to be classed as a nanoparticle, even if its other dimensions are outside that range. Today I will discuss the electrical properties of the nanomaterials or nanoparticles.
