Tailoring Crystallographic Texture Through Direct Ink Writing of Piezoelectric Ceramics
Journal of the American Ceramic Society, Volume 109, Issue 4, April 2026.A novel additive manufacturing approach is demonstrated, using needle‐like template particles with preferred crystallographic orientation that align during additive manufacturing. This combines freedom in geometrical design with local crystallographic control that can increase functional properties, here demonstrated as a doubling of the piezoelectric ...

EURASIP Journal on Advances in Signal Processing, 2006 Carrier frequency offset (CFO) is a serious drawback in orthogonal frequency division multiplexing (OFDM) systems. It must be estimated and compensated before demodulation to guarantee the system performance. In this paper, we examine the performance of

ChemSusChem, Volume 19, Issue 5, 13 March 2026.The substrate‐solvent interactions play a major role in the modified OxFA process. Herein, the formation and stability of several reaction intermediates via acetalization depending on solvent composition and reaction conditions is investigated. The BioValCat (Enhanced Biomass Valorization by Engineering of Polyoxometalate Catalysts) project aims at ...

Dianci bileiqi, 1999 针对串补系统的稳态计算，提出了一种基于ＭＯＶ两端电压谐波分析的ＭＯＶ线性模型，该模型比以前基于经验公式的ＭＯＶ线性模型具有更强的针对性和更广的适用范围。该模型应用于串补系统的短路计算，可确定短路期间ＭＯＶ的线性阻抗，不仅可以得出短路电流，而且可以计算ＭＯＶ两端的电压波形和每个周波流过ＭＯＶ的能量，与ＥＭＴＰ计算结果的比较表明该模型具有较高的准确性。

Dianci bileiqi, 2017 金属氧化物限压器（MOV）作为输电线路串联补偿装置的重要组成部分,限制系统故障时电容器极间的暂态过电压。MOV通常由多个单元并联构成,故障瞬间会通过大电流、吸收高能量。MOV单元间暂态负荷应力的分布状况直接影响MOV的保护特性,应通过优化设计确保其暂态运行可靠性。以某500 kV交流超高压带串补装置的系统为例建立了数值仿真模型,利用EMTP-ATP研究了串联补偿装置在不同运行方式下区外故障和区内故障时MOV的负荷应力。综合MOV的电压-温度特性试验结果 ...
