Abstract Grain boundary diffusion (GBD) of multiple rare earths has proven effective in enhancing the performance permanent magnets, whereas behaviors are still unclear due to their intricate interactions. In this work, synergistic effects three (Tb, Ce, and La) on grain boundaries process investigated, achieving a high‐performance diffused Nd–Fe–B magnet with high coercivity 1822 kA m −1 thermal stability −0.447% K . This promotion originates from improved depth Tb at specific regions,...
Developing aluminium gallium nitride deep-ultraviolet (UVC) micro-light-emitting diodes (micro-LEDs) with sufficient power has been a challenge, which particularly limits these devices to various applications. However, advanced fabrication processes have developed enable the demonstration of highly efficient 270 nm UVC micro-LEDs and large-format micro-LED displays high resolution for maskless photolithography. Optical electrical characterizations were performed on sizes ranging from 3 µm...
Nanocrystalline 2:14:1-type Ce–Fe–B alloy powders show potential application for low-cost hard magnets, but it is still a big challenge to prepare bulk anisotropic magnet. In this study, we investigated the fabrication of Ce–Fe–B, (Ce,La)–Fe–B and (Ce,La,Y)–Fe–B magnets by hot-deformation. It found that no texture can be obtained ternary after deformation due lack rare-earth rich phase. However, clear preferred orientation in with La substitution Ce. The formation attributed reduced amount...
Aramid fibers exhibit impressive mechanical properties, electrical insulation and chemical stability. However, physical properties of the aramid paper are poor because inertness smooth surface fibers. This study reports a simple efficient method for substantially improving performance para-aramid/meta-aramid composite by introducing N,N-dimethylacetamide (DMAc)/LiCl solution to induce partial dissolution or adding DMAc/LiCl/para-aramid regeneration. Experimental results state that tensile...
The conversion of ubiquitous hygrothermal resources into renewable energy offers significant potential for cable-free, self-powered systems that can operate worldwide without regard to climatic or geographic limitations. Here, an all-printed flexible hygro-thermoelectric paper generator is demonstrated uses bifunctional mobile ions and electrons make the moist-diffusion effect, Soret Seebeck effect work synergistically. In ordinary settings, it generates unconventional output pattern shows...
The flexible and transparent film heaters (FTFHs) with the advantages of mechanical flexibility, portability, excellent electrothermal performance, are key to next generation portable, wearable thermal protection systems. However, present substrates FTFHs fabricated by typical plastic PET films, which suffer from poor interfacial adhesion thermally conductive materials. In this work, regenerated cellulose fibers made completely dissolved in NMMO solution followed regeneration process is...
