How does a conduction welder work?

What are the microscopic mechanisms for thermal conductivity engineering?

More microscopic mechanisms for thermal conductivity engineering are discussed in the next section. Also, active sources such as electric fields, pressure and chemical stimulation enable reversible and even dynamic tuning of the thermal conductivity (see the section on the active manipulation of heat transfer).

Can metamaterials control macroscopic heat conduction?

The lack of some features typical of metamaterials simplifies design and fabrication, but also restricts performance and applications. A major challenge is to break these restrictions and discover new mechanisms for the control of macroscopic heat conduction. Some opportunities may exist at the microscale.

What is heat conduction & thermal conductivity?

Heat conduction is the main form of heat transport in solids. Engineering the thermal conductivity is central to its manipulation. At the macroscale, such manipulation has been demonstrated in various conductive thermal metamaterials.

How is heat conduction manipulated?

Many current lines of research on the manipulation of heat conduction are based on microscopic mechanisms. At the macroscale, there are fewer degrees of freedom; thus, designing the spatial distribution of thermal conductivity (including the geometric boundaries and interfaces) constitutes the majority of present passive approaches.

How do thermal metamaterials and devices manipulate heat transfer?
