Verwey transitionspin glassRFe2O4ErFe2O4Ferroelectric barium titanate (BaTiO3) ceramics have been prepared from barium acetate [Ba(CH3COO)2] and titanium isopropoxide [Ti(CH3)2CHO)4] precursors by sol-gel technique The as-grown powder was found to be amorphous which crystallized to ...
diffuse phase transitionPEZTPolycrystalline samples of Pb1-z Eu z (Zr0.60Ti0.40)1-z/4O3 (z = 0.07, 0.08 and 0.10) (abbreviated as PEZT) were prepared through the metal-alkoxide sol-gel route. X-ray diffraction analysis indicates that the PEZT compounds (nearly single phase) or solid-...
These results suggest that chromosome organization near the sol-gel phase transition dictates the timing of genomic interactions to orchestrate gene expression and somatic recombination.doi:10.1038/s41467-019-10628-9Nimish KhannaYaojun ZhangJoseph S. Lucas...

sol-gel溶胶凝胶法 Che5700陶瓷粉末處理 溶膠凝膠法Sol-GelProcess 由於應用日廣,所以經常被獨立出來,自成一類;主要係使用金屬醇氧化物alkoxide,進行水解(hydrolysis)反應,然後縮合聚合(condensationpolymerization),得到所希望的粒子因為過程中,系統黏度逐漸增加,所以也可以進行覆膜程序,even採取一體成形...
Using the sol-gel auto-combustion technique, Pb1-xCoxFe12O19 ferrite nanoparticles (with x = 0.0, 0.25, 0.50, 0.75, or 1.0) were synthesized. This study elucidates how the increasing substitution ratio of Co2+ ions lead to the transformation of the lead hexagonal ferrite phase (PbFe1...
Differential thermal analysis (DTA) was performed on the sol-gel-derived powder to countercheck the crystal structure, ferroelectric (FE) to paraelectric (PE) phase transition, and melting point of bismuth ferrite. We observed a significant exothermic peak at 840 掳C in DTA graphs, which ...
