Electric field induced antiferroelectric-ferroelectric phase transition is a double-edged sword for energy storage properties, which not only offers congenital superiority with substantial density but also poses significant challenges such as large polarization hysteresis and poor efficiency, deteriorating the operation service life of capacitors. Here, entropy increase effect utilized to simultaneously break long-range antiferroelectric order locally adjust fourfold commensurate modulated...
Metal matrix composites with near-zero thermal expansion (NZTE) have gained significant popularity in high-precision industries due to their excellent stability and mechanical properties. The incorporation of Mn3Zn0.8Sn0.2N, which possesses outstanding negative properties, effectively suppressed the titanium. Highly dense Mn3Zn0.8Sn0.2N/Ti were obtained by adjusting fabrication temperature. Both fabricated at 650 °C 700 exhibited NZTE. Furthermore, finite element analysis was employed...
Concentration gradient generation is of great importance for high-throughput drug screening. The classic Christmas tree structure typically used generating concentration gradients with uniform distribution. However, the variation in lengths outlet channels Christmas-tree causes serious biases generated values. This paper first quantifies gradients, and then proposes a fast look-up table-based method, along further Bayesian Optimization method tuning given order to enhance uniformity...
Atmospheric data assimilation is essential for numerical weather prediction. Ensemble connects multiple instances of an atmospheric model through a Kalman filter-based algorithm, which regarded as challenging computing task today. In this work, we build fast, low-cost, and scalable prototype, DIDA, the new-generation Sunway supercomputer, including: (1) framework that enables flexible deployment components, manages optimizes communication among modules, achieving maximum resource efficiency;...
The salient feature of low-expansion metal matrix composites is their dimensional stability. Due to the limitation performance reinforcement, current composite materials cannot achieve both low expansion and high mechanical strength at same time. With its extremely negative thermal behavior metallic characteristics, anti-perovskite manganese nitrogen compound can be used as an ideal inhibitor prepare materials. In present work, fully-dense Mn3.2Zn0.5Sn0.3N/Al with have been successfully...
Mismatched thermal expansion coefficients between perovskite and substrate tend to induce residual tensile strain. Strain, as a critical factor of instability, not only harms the efficiency PSCs but also accelerates degradation devices. In this report, we introduce novel negative (NTE) material relieve strain for first time, thanks an offset strategy that reduces overall coefficient. Multiple positive effects, including promoting crystallization, enabling high-quality films, optimizing...
Negative thermal expansion particles can be used as compensation for metal matrix composites to achieve near-zero materials. However, there are huge residual mismatch stresses in the due between and reinforcement. The use of hybrid reinforcement is required solve stress concentration problem. In this study, Al reinforced with ZrW2O8 SiC reinforcements (SiCp, SiCnw) were fabricated by pressure infiltration process. effect content on microstructure, phase composition, mechanical properties...
