Abstract

A simple theoretical model is developed to study the effect of temperature on nanomaterials. It is found that the volume thermal experimental data for nanomaterials under study can be reproduced satisfactorily with the help of Liu model, which takes into account the temperature dependence of the Anderson- Grüneisen parameter. The Anderson model for investigating the temperature dependence of volume expansion of some nanomaterials viz. Zirconia, Ag, ZnO, NiO and Al compounds have been used by Kumar model to obtain results in an approximately fair agreement with the available experimental data. The model used by them is based on the assumption that the Anderson-Gru ̈neisen parameter does not depend on temperature.
