Interests: Prof. Xuexi Zhang’s research interests covers the shape memory alloys (SMAs) and teir underlying functional properties for sensors, actuators and solid-state cooling applications. He paied much attention on low-dimensional ferromagnetic shape memory alloys, including foams, microres and paticles, for tailoring the structures and properties of caloric cooling, e.g. refrigeration capacity, working temperature window, cycling stability and reversiblity. His research interests also covers the metal-matrix composites for advanced structures in industries.  

Special Issue Information

Aim and Scope: In the past decades, solid-state cooling based on the various caloric effects has become an emerging technology which may provide the solution to replace the traditional vapor compression technique due to its high efficiency, inexpensive and eco-friendship. The caloric related materials undergoing phase transitions may exhibit the large adiabatic temperature change or isothermally entropy change under the influence of magnetic fields, uniaxial stresses, hydrostatic pressure or electric field, which corresponds to magnetocaloric effect (MCE), elastocaloric effect (eCE), barocaloric effect (BCE) or electrocaloric effect (ECE). In recent years, researchers have paid more and more attention to various novel caloric related materials, such as ferromagnetic shape memory alloys (FMSMAs) and rare-earth containing compounds, with the aim to achieve the properties for near-future applications. In order to reveal the great development in this emerging field of caloric effects and related materials, the collection aims to gather high quality papers in the topic of material design, processing-microstructure-property characterization and application.

Abstract: The electrocaloric effect (ECE), which refers to a temperature change of a dielectric when applying or withdrawing an electric field, draws promising applications in solid-state cooling due to its high energy efficiency and environmental friendliness. The ECE includes two types, that is a positive effect and a negative effect, and it is reported that the combination of both positive and negative ECE can remarkably enhance the overall cooling ability of materials. Different from the widely existing positive ECE, negative ECE occurs in limited cases, that is, in ferroelectrics with different polar directions, in materials with defect induced internal bias fields, and the most importantly in antiferroelectrics. In this review, the fundamental theory and origin of the negative ECE are described and recent progress of negative ECE in antiferroelectric materials is especially focused. Finally, the existing challenges and future research directions are discussed.

Abstract:  Magnetocaloric cooling has remained a promising thermal regulation technology alternative to the >150-year-old vapor-compression based technology for over 3 decades.  While a slew of magnetocaloric materials are known, they are routinely studied in their primitive particle, or bulk, form, and their reported caloric properties typically vary when the material is processed and fabricated into a real-world device regenerator, among a huge backdrop of regenerator bed engineering concerns. This focused article intends to address such shortcomings for magnetocaloric cooling development by critically assessing the most current reports on post-processing and fabrication of magnetocaloric regenerators by providing analysis and insight on relevant property-composition-fabrication relationships and trends.  Issues addressed are mechanical and chemical instability, deleterious effects to caloric properties by processing as well as difficulties in obtaining precise geometries of regenerators.  This review aims to encompass the methods of producing a magnetocaloric regenerator and suggests future outlook toward the development and manufacturing of 3D printed magnetocaloric bed architectures:  a project currently underway by the authors.
