Today I will discuss the electrical properties of the nanomaterials or nanoparticles. There is a fairly simple explanation of why small-enough particles are different from bulk materials. These nanoparticles are manipulated by the use of magnetic field. For example, nanoparticles of sizes about 90 nm absorb red to yellow light and emit blue-green, whereas particles around 30 nm in size absorb blue and green light and appear red in color. Why do nanoparticles have different properties to bulk material. The actual mechanisms that give specific colour may vary, but the main point is that the size of the particle comes to dominate the bulk properties of the material. The effect of size in the catalytic properties of gold nanoparticles supported on glassy carbon is investigated in the paper Glassy carbon electrode-supported Au nanoparticles for the glucose electrooxidation: on the role of crystallographic orientation, by M. Guerra-Balczar et al. vertical-align: -0.1em !important; "Properties of Nanoparticles". - Definition, Examples and Uses, What are Nanoparticles? in the paper entitled Catalysis of methanol-air mixture using platinum nanoparticles for microscale combustion.

Just as the bulk material would, titanium oxide nanoparticles are able to provide improved UV protection while also having the added advantage of removing the cosmetically unappealing whitening associated with sunscreen in their nano-form. Gold and silver are relatively inert in bulk amounts. Bulk nanostructures none of the dimensions is in the nanoscale (all are above 100 nm). for the detection of ethylene gas. Another besides Bulk is Temperature 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. What is difference between the large size particles and nanoparticles? National Structural Integrity Research Centre, Granta Park, Great Abington, Cambridge, CB21 6AL, UK. What do allotropes have in common? The specific properties of nanoparticles is defined by particle size, chemical composition, crystallinity and shape.
