What is the difference between nanoparticles and nanostructures?
Eduedmais
In describing nanostructures it is necessary to differentiate between the number of dimensions on the nanoscale. Nanotextured surfaces have one dimension on the nanoscale, i.e., only the thickness of the surface of an object is between 0.1 and 100 nm. Nanotubes have two dimensions on the nanoscale, i.e., the diameter of the tube is between 0.1 and 100 nm; its length could be much greater. Finally, spherical nanoparticles have three dimensions on the nanoscale, i.e., the particle is between 0.1 and 100 nm in each spatial dimension. The terms nanoparticles and ultrafine particles (UFP) often are used synonymously although UFP can reach into the micrometre range. The term 'nanostructure' is often used when referring to magnetic technology.

How are nanoparticles useful in producing industrial catalysts?
Can you recognize Cu nanoparticles without TEM microscopy?
Nanostructures represent the smallest human-made structures that can be built?
Yes
Who found nanoparticles?
Michael Faraday is generally considered to be the first person to conduct scientific research on nanoparticles.
What is the effect of silver nanoparticles in plastic?
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.
Do nanoparticles have colors?
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.
What are Zero-Dimensional Nanostructures?
Nanoparticles and quantum dots are the zero dimensional structures.
What are plasmonic nanostructures?
Plasmonic nanoparticles are particles whose electron density can couple with electromagnetic radiation of wavelengths that are far larger than the particle.
What is the difference between nanoparticles and nanotechnology?
nanoparticles are basicly microscopic particles. Nanotechnology is the technology used to manipulate these nonoparticles for human use.
What is the difference between nanoparticles and nanomaterials?
Different code words for the same concept.
What is the difference between nano and bulk material?
Nanoparticles behave quite different from their bulk of the same composition due to the high surface to volume ratio.
What has the author V A Shchukin written?
V. A. Shchukin has written: 'Epitaxy of nanostructures' -- subject(s): Nanostructures, Epitaxy
How are nanoparticles constructed in to mascara's?
Nanoparticles are put into mascara\'s to reduce clumping. Nanoparticles are made out of the soot from a candle flame.
Why are nanoparticles used in textiles?
because teh nanoparticles are so good

Can you recognize Cu nanoparticles without TEM microscopy?
Are nanoparticles the same as ordanary particles?
no they are not. nanoparticles are much smaller than normal/ordinary particles
Nanostructures represent the smallest human-made structures that can be built?
Yes
