Question

Write short notes on Effect of temperature on size of nanoparticles.

Answer 1

Hey dear,

the effect of temperature at the synthesis of gold nanopaticles,which is showing unusual behaviour,at room temperature there is higher intensity of absroption peak as compared to temperature raise to 40C,at further increasing temperature to 60C there is rise in absorption intensity up to 80C,with peak broadening at 80C,but at 100c there is decrease in intensity with broad peak width,

You're answer -

Answer 2

Answer:

The particle size and shape are demonstrated to affect the specific heat, melting entropy and enthalpy of nanomaterials. ... The specific heat is observed to increase with the decrease in particle size, whereas the melting entropy and enthalpy decrease as the particle size decreases.
