Yes, it is possible to see nanoparticles, but not with the naked eye due to their extremely small size, typically in the range of 1 to 100 nanometers. Advanced imaging techniques such as transmission electron microscopy (TEM) or scanning tunneling microscopy (STM) are required to visualize them. These methods can provide detailed images of nanoparticles, allowing scientists to study their properties and interactions at the nanoscale.
What else can I help you with?
Can electron excitation happen in a semiconductor nanoparticle without light or thermal energy?
Yes, electron excitation in a semiconductor nanoparticle can occur without light or thermal energy through mechanisms like electrical injection, impact ionization, or tunneling. These processes can lead to electron promotion across energy levels within the nanoparticle, resulting in excitation.
What is melting point of silver nanoparticle?
The temperature of the melting point is related to the size of the nanoparticle. For smaller particles, melting begins around 600 °C.
What is the role of surfactant in nanoparticle synthesis?
Surfactants are used in nanoparticle synthesis to control particle size, shape, and stability. They help in preventing agglomeration of nanoparticles by acting as a protective layer around them, and also facilitate the dispersion of nanoparticles in the reaction medium. Surfactants can influence the growth kinetics of nanoparticles and play a crucial role in determining the final properties of the synthesized nanoparticles.
Is it possible to see 9 shooting stars in a single night?
It is possible to see hundreds of shooting stars in a single night, during a meteor shower.
Can one get 1nm size particle?
Yes, it is possible to create particles that are 1nm in size through techniques such as nanoparticle synthesis or manipulation at the nanoscale level. Various methods such as chemical processes, physical vapor deposition, or self-assembly can be employed to control the size and shape of nanoparticles at the nanometer scale. Advanced nanotechnology tools and instruments are essential for producing and characterizing particles at such small dimensions.
When was Journal of Nanoparticle Research created?
Journal of Nanoparticle Research was created in 1999.
How does a nanoparticle differ from a single ion How does it differ from a piece of a solid?
The size of a nanoparticle is smaller than any one piece of a solid; also an ion is smaller than a nanoparticle.
