Gallium (Ga)-based liquid metal (LM) has attracted great interest for thermal management due to its high conductivity (Tc). However, the surface tension of LM is too wet heat source and sink, there are risks a short circuit devices caused by leakage. The also makes it difficult well mix fillers prepare composite paste interface application. We found that contact angle on Boron nitride (BN) pill could decreased from 133° 105° doping tungsten (W) nanoparticles indicating be W nanoparticles....
The capacitors are in rising demand for cryogenic applications. As now, it still remains an ongoing challenge simultaneously achieving high energy storage density and temperature stability. Herein, the strategy of stable backward phase transition was demonstrated antiferroelectric composition (Pb0.9175La0.055)(Zr0.975Ti0.025)O3. a result, we achieved recoverable about 10 J/cm3 with exceptional low-temperature stability from −160 to 25 °C. Multi-layer ceramic designed pulse discharge...
Antiferroelectric and ferroelectric materials are prominent non-linear dielectric with significant applications across various fields. To fully understand their electrical properties, it is crucial to accurately discriminate the two phases, especially in compositions coexistence of antiferroelectric phases. In this study, we propose an easy method for differentiating domain structures from phase based on split outskirt reflections. The proposed addresses existing limitations spatial...
Dielectric ceramics with ultrahigh polarization and energy density are the core components used in next-generation pulse power generators based on explosive conversion. However, low of ferroelectric materials high depolarized pressure hinder their development toward miniaturization, light weight, integration, while antiferroelectric possessing larger nonlinear saturated rich phase structure neglected Here, an effective strategy constructing antiferroelectric-to-ferroelectric overlap zone is...
