Summary: Caloric materials, especially those exhibiting the magnetocaloric effect (MCE) in coordination polymers, have great potential in replacing conventional cryogenics. The unique structural flexibility of coordination polymers allows for a wide range of structures, and materials containing Gd as the magnetic center have shown promising magnetocaloric properties at ultra-low cryogenic temperatures. There is also growing interest in optimizing the magnetocaloric effect for lower applied fields using tailored magnetic interactions and incorporating other magnetic cations. This review discusses the most promising magnetocalorics in coordination polymers and MOFs, emphasizing their structural characteristics and providing a brief perspective on the future of this field.

Summary: Experimental elastocaloric polymer coolers using natural rubber tubes were developed with two different geometries. The suitable geometry compensated for the low thermal conductivity and achieved performances comparable to other caloric devices. One of the prototypes exhibited a maximum temperature span > 8K, a maximum COP of 6, and an output cooling power of 1.5W, outperforming other prototypes based on polymers or ceramics. This breakthrough enables the realization of realistic elastocaloric polymer coolers on a larger scale.

Summary: The study aimed to evaluate the influence of intraocular pressure (IOP) increase and ocular biometry changes on corneal optical coherence tomography (OCT) speckle distribution in ex-vivo experiments on porcine intact eyes. The results showed that the parameters of the gamma distribution varied significantly with IOP and time, and a significant correlation was found between central corneal thickness and the speckle distribution parameter. This approach may be potentially utilized for noninvasive assessment of corneal stroma properties.

Summary: This paper proposes and studies a piston-type thermally-driven pump with a structure similar to a linear compressor, aiming to eliminate the high-quality energy consumption of existing pumps and replace mechanical pumps. The coupling mechanism of working fluid flow and element dimension is analyzed based on force analysis, and experimental data analysis is used to determine the pump operation stroke. Theoretical simulation is conducted to analyze the correlation mechanism of the piston assembly. The research shows that the thermally-driven pump can greatly reduce power consumption and has potential for industrial applications.
