Caloric materials for efficient heat management applications: advances and challenges

The topic of the symposium are caloric materials and their related phenomena. This timely topic is currently attracting a considerable attention of the worldwide scientific community due to their great potential for new environmental-friendly cooling applications in wide market niches ranging from microelectronics to macro cooling devices.

Scope

Caloric effects stand for one of the main fields of research regarding solid state cooling. The caloric effect are either magnetocaloric (MC), electrocaloric (EC) or mechanocaloric (mC) – where the material of interest entropy changes under the application of external stimuli – magnetic, electric, or mechanical, respectively. For example, in EC cycle, a dipolar system such as ferroelectric material is used in the cycle instead of gas medium that is usually harmful for environment. Electric field plays there the role of pressure. However, caloric materials still exhibit many drawbacks (for example effect not large enough or costly materials) that need to be overcome before they can be considered in commercial devices. Besides the design and development of such devices is crucially needed. Moreover, the underlying mechanisms of these effects are still not fully understood, which means that thorough theoretical approaches (including first and second principles) are required. Studies on MC, EC and mC materials have mostly been carried out by different communities so far. For example, the MC community is traditionally involved in other magnetism-related fields while the EC researchers more often come from the world of ferroelectric ceramics. This symposium will join together three communities, all working on caloric materials for cooling applications, but presently not very well connected.  The speakers will discuss caloric effects including multicaloric, inverse caloric, giant phenomena, among others, in crystals, ceramics, thin films, soft (polymers, liquid crystals) or organic materials and their integration for applications.

Hot topics to be covered by the symposium

MC, EC and mC materials and devices, multicaloric effect, inverse caloric effect, soft and solid caloric materials, theoretical approaches for understanding the underlying mechanisms in calorics, coupling of caloric phenomena with other effect in materials, prototypes.
