Abstract

A critical analysis of size and shape dependence properties of different type of nanomaterials is presented using a simple theory of equation of state (EOS) and bulk modulus. It is observed that compression behavior of nanomaterials depends on size and shape in addition to the applied pressure. To confirm the situation we have considered different type of nanomaterials. The model predictions are compared with the available experimental data. A good agreement between theory and experiments demonstrate the validity of model proposed for nanomaterials. Some results have also been reported in absence of experimental data to help the researcher engaged in the experimental studies of nanomaterials. Due to the simplicity and applicability of the model, it may be used to understand other properties of nanomaterials under varying physical conditions.

纳米材料的状态和体积模量的尺寸和形状依赖方程

利用简单的状态方程(EOS)和体积模量理论，对不同类型纳米材料的尺寸和形状依赖特性进行了批判性分析。研究发现，纳米材料的压缩性能除了与施加的压力有关外，还与材料的尺寸和形状有关。为了证实这种情况，我们考虑了不同类型的纳米材料。将模型预测结果与现有实验数据进行了比较。理论与实验结果吻合良好，证明了该模型对纳米材料的有效性。在缺乏实验数据的情况下也报道了一些结果，以帮助研究人员从事纳米材料的实验研究。由于模型的简单性和适用性，它可以用来理解纳米材料在不同物理条件下的其他性质。

期刊介绍： High Temperatures – High Pressures (HTHP) is an international journal publishing original peer-reviewed papers devoted to experimental and theoretical studies on thermophysical properties of matter, as well as experimental and modelling solutions for applications where control of thermophysical properties is critical, e.g. additive manufacturing. These studies deal with thermodynamic, thermal, and mechanical behaviour of materials, including transport and radiative properties. The journal provides a platform for disseminating knowledge of thermophysical properties, their measurement, their applications, equipment and techniques. HTHP covers the thermophysical properties of gases, liquids, and solids at all temperatures and under all physical conditions, with special emphasis on matter and applications under extreme conditions, e.g. high temperatures and high pressures. Additionally, HTHP publishes authoritative reviews of advances in thermophysics research, critical compilations of existing data, new technology, and industrial applications, plus book reviews.
