纳米材料和散装材料之间的差异

Thekey differencebetween nanomaterials and bulk materials is that the纳米材料有其规模在1 - 100纳米范围least in one dimension whereas the bulk materials have their size above 100 nm in all dimensions.

Nanomaterials and bulk materials are the two major types of particles. They differ from each other according to their size. Moreover, they have different chemical and physical properties. Therefore, they have different applications as well.

What are Nanomaterials?

Nanomaterials are particles that have their size in 1-100 nm range at least in one dimension. There are different sources of these particles. For example, we can get these particles as engineered particles, as incidental components and via natural sources. There are several forms of nanomaterials;

1. Nanomaterials – They have all their dimensions in 1-100 nm scale.
2. One dimensional nanostructure – one dimension has its size outside the nanoscale.
3. Two-dimensional nanostructures – two of the dimensions are not in nanoscale.
4. Bulk nanostructures – none of the dimensions is in the nanoscale (all are above 100 nm).

这些材料在各种制造过程，医疗保健应用，包括油漆，过滤器，润滑剂添加剂等各种产品中有许多应用。

What are Bulk Materials?

Bulk materials are particles that have their size above 100 nm in all dimensions. Most of the times, we use this term in order to name a substance that is granular or lumpy and exists in free-flowing form. we use the grain size and grain distribution in characterizing these materials. Moreover, we can explain their properties using the bulk density, moisture content, temperature, etc. There are two forms of these materials as follows:

1. Cohesionless, free-flowing bulk materials
2. Cohesive bulk materials

散装材料包括我们在建筑领域使用的材料；此外，它还包括我们用于矿石，炉渣，盐等各种行业的原材料。除此之外，还包括粉状材料，例如颜料，填充剂，颗粒，颗粒，颗粒， ETC。

纳米材料和散装材料有什么区别？

Nanomaterials are particles that have their size in 1-100 nm range at least in one dimension. We cannot see their particles through the naked eye. Moreover, examples of these materials include nanozymes,titanium dioxidenanoparticles,graphene， ETC。Bulk materials are particles that have their size above 100 nm in all dimensions. We can see their particles through the naked eye. The examples of these materials include plaster, sand, gravel, cement, ore, slag, salts, etc. The below infographic presents the difference between nanomaterials and bulk materials in tabular form.

概括– Nanomaterials vs Bulk Materials

Nanomaterials are invisible to the naked eye. But the bulk materials, we can see their particles. The difference between nanomaterials and bulk materials is that nanomaterials have their size in 1-100 nm range at least in one dimension whereas bulk materials have their size above 100 nm in all dimensions.
