The term "thermal expansion" most often refers to the external parameters, which are more easily and accurately measured. Here we use "thermal expansion" to mean both external and internal parameters. Internal thermal expansion impacts a wide range of applications, but has been given less ...
Thermal expansion, the general increase in the volume of a material as its temperature is increased. It is usually expressed as a fractional change in length or volume per unit temperature change; a linear expansion coefficient is usually employed in des
refers to the phenomenon where a material contracts rather than expands upon heating, of potential importance for further development in the field of thermal expansion compensator. Recently, a Zn2(1,2,4-triazolate)2(oxalate) framework named CALF-20, was proposed as a benchmark sorbent for CO2...

area and volume when subjected to a temperature variation is known as its thermal expansion property. From the engineering point of view, the thermal expansion coefficients of composites are very important with regard to their dimensional stability and the mechanical compatibility when they used with ...
The formation of HfMo2O8 leads to crack formation and delamination because of its negative thermal expansion coefficient, which means the inward diffusion of oxygen is the dominant degradation mechanism for concentrating solar power systems [101]. In addition, TMNs have attracted significant attention ...
refers to a time and space average of light fields in the far-field. Inside the bracket is, in fact, the Poynting vector of a light field. As WGP structure finds increasingly more applications on a micro and nanoscale, thermal characteristics become extremely important to understand, because ...
Moreover, µn f represents the dynamic viscosity of the nanofluid, ρn f refers to the density of the nanofluid, (ρβ)n f denotes the thermal expansion coefficient of the nanofluid as described in the Brinkman's model, ρCp n f denotes the heat capacitance of the nanofluid, αn f ...
Most systems are upgraded (additional RAM, adapter cards, drives, etc.) sometime during their life. Integrators should test systems with some expansion cards installed in order to simulate a system that has been upgraded. A thermal management solution that works well in a system that is heavily...
where 𝑨𝑖𝑗𝑘𝑙Aijkl is a symmetric and positive definite elastic tensor, 𝒂𝑖𝑗aij is a tensor that stands for thermal expansion coefficient, and T stands for temperature. Ignoring the viscosity factor during deformation, the total strain 𝜺𝑖𝑗εij is the sum of three comp...
