Molar volume and surface tension of nanoparticle

Click For Summary

Discussion Overview

The discussion revolves around the calculation of molar volume and surface tension of nanoparticles, specifically in their pure state. Participants explore whether these parameters can be calculated or if they are available in existing literature or tables.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant inquires about the methods for calculating molar volume and surface tension of nanoparticles, questioning whether these values are readily available in tables.
  • Another participant expresses confusion regarding the initial question, suggesting it may pertain to the properties of a fluid containing suspended nanoparticles.
  • A subsequent reply clarifies that the nanoparticles are in a pure state and are intended to absorb asphaltene dissolved in toluene, emphasizing the need for data on molar volume and surface tension prior to absorption.
  • One participant asserts that surface tension is a concept relevant only to interfaces between two fluids, indicating that it does not apply to solids, but notes that the surface tension of a nano-fluid can be determined once the nanoparticles are suspended in a fluid.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the applicability of surface tension to nanoparticles in their pure state, and there is disagreement regarding the interpretation of the initial question about the properties of nanoparticles.

Contextual Notes

The discussion highlights the ambiguity in defining surface tension in the context of solid nanoparticles and the potential confusion regarding the state of the nanoparticles being discussed.

Hi .how can i calculate the molar volume and surface tension of nanoparticles ? shoud i have to calculate? or these parameters is available in tables or sth?

Sorry but I don't understand what you are really asking about in your question .

Are you possibly asking about the properties of a fluid containing a suspension of nanoparticles ?

No,Nanoparticles are in pure state and they want to absorb asphaltene dissolved in toluene. I want to have data on molar volume and surface tension of nanoparticles in pure state (i.e. before absorption)
 
As far as Surface tension is concerned,It is a concept that is applicable only to surfaces that separate two fluids.There is no such thing applicable for solids.However,you can find the ST of a nano-fluid once you suspend the particles in the fluid.
