Surface area to volume ratio in nanoparticles have a significant effect on the nanoparticles properties. Firstly, nanoparticles have a relative larger surface area when compared to the same volume of the material. For example, let us consider a sphere of radius r:
The surface area of the sphere will be 4πr2
The volume of the sphere = 4/3(πr3)
Therefore the surface area to the volume ratio will be 4πr2/{4/3(πr3)} = 3/r
It means that the surface area to volume ration increases with the decrease in radius of the sphere and vice versa.
If the ratio of similarity is 310, then the ratio of their area is 96100.
an eqivalent ratio is an ratio that is equal or you can simplfiy it
Unit Ratio- a ratio that has a denominator of 1
There is no single ideal ratio.
i am the ratio of the sum 2,3 and 4 to the product of these numbers what ratio am i
Nanoparticles are put into mascara\'s to reduce clumping. Nanoparticles are made out of the soot from a candle flame.
Nanoparticles behave quite different from their bulk of the same composition due to the high surface to volume ratio.
because teh nanoparticles are so good
Can you recognize Cu nanoparticles without TEM microscopy?
no they are not. nanoparticles are much smaller than normal/ordinary particles
Nanoparticles are used for various purposes due to their unique properties at the nanoscale. They offer a large surface area to volume ratio, which makes them useful for catalysis, drug delivery, and sensing applications. Additionally, nanoparticles exhibit quantum confinement effects, allowing for manipulation of their optical, electronic, and magnetic properties.
Michael Faraday is generally considered to be the first person to conduct scientific research on nanoparticles.
Silver nanoparticles are antibacterial, and when embedded in plastics for use in the medical field, are non-toxic. This makes silver nanoparticles useful in plastic applications such as surgical catheters.

We cant really see nanoparticles to tell if they have colours, some do depending on what they are made from, but more commonly we see nanoparticles as a suspension in water, ethanol or some other solvent. These solutions can give rise to some intense colours, this is due to raylaigh scattering that takes place from the nanoparticles. A phemonon called surface plasmon resonance also has a part to play in the colours that we see for colloidal nanoparticles.
