The piezoelectric strain coefficient d33* always deteriorates rapidly with increasing temperature, which is one of the technical bottlenecks restricting practical applications ceramics at high temperatures. Herein, we successfully prepared (1 – x)(0.7BFeO3-0.3Ba(Hf0.05Ti0.95)O3)-x(Bi0.2Sr0.7)TiO3 by conventional solid-state method, possessed a = 490 pm/V 245 °C. In particular, insensitive to temperature range 25 Microstructure characterization and electrical performance measurements showed...
Herein, x Co 0.8 Cu 0.2 Fe 2 O 4− y (0.8BaTiO 3 –0.2BiAlO ) [ CCFO– (BTO–BA)] ( = 0, 1; 1, 2; 4; 6) magnetoelectric composite ceramics are synthesized by solid‐state method. The effects of composition on the microstructure, dielectric, ferroelectric and magnetic properties systematically investigated. Two‐phase structures were confirmed X‐ray diffraction patterns, which correspond to (BTO–BA) CCFO phases; a little impurity can be found, this low‐concentration secondary phase is indexed as...
Two-way fiber-optic time transfer (TWFTT) is a promising precise synchronization technique with subnanosecond stability. However, the asymmetric delay attack severe threat, which can deteriorate performance of TWFTT system. In this article, clock model-based scheme used to defend attack. For scheme, security threshold set according two-state model, and estimated frequency difference excluded from measured detect Systematic detection mitigation for developed in article. Theoretical simulation...
Magnetoelectric composites have attracted much attention due to their strong magnetoelectric coupling effect. In this paper, PbTiO3-NiFe2O4 (PTO/NFO) composite ceramics were prepared by sol-gel method. Effect of sintering temperatures on the structure, dielectric properties and multiferroic studied. XRD results show that PTO/NFO been successfully prepared. When temperature is 1050 °C, secondary phase PbO2 exists in ceramics. SEM there two kinds grains with different sizes. EDS analysis...
Abstract Ceramic/polymer nanocomposites have been extensively explored for dielectric capacitor application due to their high energy storage performance and ease of processing, flexibility, low cost. However, improving compatibility between inorganic organic materials is great significance has a long‐standing challenge. In this work, the polymer surfactant Pluronic™ F127 was employed perform surface modification BaTiO 3 through facile solution process. The nanoparticles P (VDF‐HFP) can be...
Metamaterials are artificial materials with properties depending mainly on their designed structures instead of materials. Pentamode metamaterials one type metamaterial. They have solid fluid-like properties, which can only withstand compressive stresses, not shear stresses. Two-dimensional pentamode easier to manufacture than three-dimensional models, so they received wide attention. In this review, the manufacturing, and applications two-dimensional will be discussed. Their water-like most...
