基于Calphad方法,首先对CaCl_(2)-CaO、CaCl_(2)-CaF_(2)和CaO-CaF_(2)体系进行了系统的热力学评估和优化。采用置换溶液模型来描述液相和固溶体相的吉布斯自由能,所有中间相因其固溶区域十分有限而近似处理成准化学计量比化合物,且其自由能依据Neumann-Kopp规则定义。其次,利用Muggianu溶液几何模型将优化获得的所有子二元系的模型参数扩展至CaCl_(2)-CaO-CaF_(2)三元体系。最后,对共晶点进行配样和差示扫描量热法(DSC)测试,通过引入三元交互参数使计算结果与试验数据一致,从而获得了一套自洽的CaCl_(2)-CaO-CaF_(2)三元体系热力学数据库。

Oxygen permeability and CO_2-tolerance of Ce_(0.8)Gd_(0.2)O_(2-δ)-Ln BaCo_2O_(5+δ) dual-phase membranes

引用

Journal of Energy Chemistry 2015年第1期24卷 15-22页

作者： Longfei Luo Hongwei Cheng guangshi li Xionggang Lu Bo Jiang Shanghai Key Laboratory of Modern Metallurgy and Materials Processing Shanghai University

A series of oxygen permeable dual-phase composite oxides 60 wt% Ce0.8Gd0.2O2-δ-40 wt% LnBaCo2O5＋δ （CGO-LBCO, Ln = La, Pr, Nd, Sin, Gd and Y） were synthesized through a sol-gel route and effects of the Ln3＋ cations on their phase structure, oxygen permeability and chemical stability against CO2 were investigated systemically by XRD, SEM, TG-DSC and oxygen permeation experiments. XRD patterns reveal that the larger Ln3＋ cations （La3＋, Pr3＋ and Nd3＋） successfully stabilized the double-layered perovskite structure of sintered LBCO, while the smaller ones （Sm3＋, Gd3＋, and Y3＋） resulted in the partial decomposition of LBCO with some impurities formed. CGO-PBCO yields the highest oxygen permeation flux, reaching 2.8× 10^-7 ***-2 at 925 ℃ with 1 mm thickness under air/He gradient. The TG-DSC profiles in 20 mol% CO2/N2 and oxygen permeability experiments with CO2 as sweep gas show that CGO-YBCO demonstrates the best chemical stability against CO2, possibly due to its minimum basicity. The stable oxygen permeation flux of CGO-YBCO under CO2 atmosphere reveals its potential application in the oxy-fuel combustion route for CO2 capture.

Most basal-like breast cancers(BLBCs)have a poor prognosis and high crossover with triple-negative breast cancers(TNBCs).However,approximately 50%of TNBC patients develop chemoresistance.^(1) Dexamethasone reportedly induces Krüppel-like factor 5(KLF5)and can cause docetaxel and cisplatin resistance in TNBC.A super-enhancer can maintain the transcription of KLF5.
