Low grade waste heat accounts for ~65% of total heat, but conventional recovery technology exhibits low conversion efficiency recovery. Hence, we designed a thermomagnetic generator such applications. Unlike its usual role as the coil core or big magnetic yoke in previous works, here magnetocaloric material acts switch that controls circuit. This makes it not only have advantage flux reversal pretzel-like topology, also present simpler design, lower stray field, and higher performance by...
Abstract Magnetic refrigeration based on magnetocaloric effect (MCE) has become a promising cooling technology to replace the traditional vapor compression refrigeration. However, methods for searching MCE materials require producing many different compositions, causing unbearable workload and long experimental periods. Here, 3D printed La 0.7 Ce 0.3 Fe 11.65 Si 1.35 –Fe compositionally gradient alloys (CGAs) are successfully prepared using laser powder bed fusion equipped with hopper...
Materials with tunable negative thermal expansion (NTE) are highly demanded in various functional devices. La(Fe, Si)13-based compounds promising NTE materials due to their outstanding properties. However, poor mechanical properties and related short service life restrict practical applications. In this work, epoxy resin positive is used synthesize La-Fe-Si/resin composites. The of composites can be manipulated by optimizing the La-Fe-Si particle size content, tailoring content could tune...
Thermomagnetic generation (TMG), a promising technology to convert low-grade waste heat electricity, utilizes high performance TMG materials. However, the drawbacks of large hysteresis, poor mechanical properties and inadequate service life hinder practical applications. For first time, we evaluated effect different phase transitions on by systematically comparing three typical Heusler alloys with similar composition but transitions. Ni2Mn1.4In0.6 exhibits second-order magnetic transition...
Traditional thermal switches usually suffer from long-time and unidirectional response. Herein, we combined liquid metals with magnetic Ni2Mn1.4In0.6 particles developed a thermomagnetic metal. These materials not only show excellent fluidity electrical conductivity, but also exhibit fast response at tuneable temperature that traditional do have. The ultimate application is designed as micro-channel switch. Particularly, our switch features bidirectional through the droplet displacement,...
Abstract Thermomagnetic generation (TMG) is a potential technology for harvesting low‐grade waste heat. However, the limited heat transfer of TMG materials constrains their practical performance. In this study, low‐melting point metal indium (In) with high thermal conductivity introduced into Ni─Mn─In Heusler alloy to fabricate Ni─Mn─In/In composites. The increased significantly from 14.86 W m −1 K 65.2 composite. composite containing 40 wt.% (In40) exhibits superior performance, an average...
Abstract Solid‐state refrigeration technology based on elastocaloric effect (eCE) has garnered widespread attention as an emerging green technology. While shape memory polymers (SMPs) offer substantial temperature changes (Δ T ) with relatively low applied stress compared to alloys, their limited thermal conductivity poses a significant challenge for efficient heat exchange. Here, low‐melting‐point GaInSn liquid metal (LM) is introduced into thermoplastic polyurethane (TPU) develop TPU@LM...
This paper presents a new chaos-based medical image encryption algorithm using iterative permutation and substitution operation. To address the drawbacks encountered when invertible area-preserving chaotic maps, we introduce pixel swapping-based scrambling method with keystream sequence generated from logistic map. In stage, each element is 1-D map selected group of three maps according to value previous one it applies to, making dependent on plain-image. As result, robustness proposed...
Nowadays, a large amount of image information is transmitting on the internet, and people are focusing more security. These years, encryption algorithm based "scrambling-diffusion" architecture has made great achievement in security performance. Nevertheless, there no need to encrypt full image. Only part it matters, which defined as Region Interested (ROI). In this paper, we propose pixel-level method semantic segmentation. We use PSPNet model trained Cityscapes dataset gain coordinate each...
To improve the positioning accuracy of autonomous celestial navigation systems when flying in formation, we exploit fact that sole light source solar system is Sun to directly provide information for relative navigation. We term this Time Difference Arrival (TDOA) formation flying. Solar has potential a (TOA) because its unstable intensity. However, TOA cannot be used it no baseline. solve problem, took difference between TOAs two spacecraft (the TDOA) as basis navigational measurement. The...
