It is found that the flower-like CuO microspheres, which are composed of CuO nanosheets, possess an average diameter of 4.2... to their unique morphology [17]. Herein, we demonstrate a facile template-free method to fabricate flower-like CuO and flower-like CuO/graphene composite by hydrothermal method. Porous structure......
氢氧化铝晶体生长习性的Morphology分析 吴争平,尹周澜,陈启元,李 洁 (中南大学 化学化工学院 化学工程与技术博士后流动站,湖南 长沙,410083) 摘 要:对氢氧化铝晶体生长习性进行Morphology理论研究,明确氢氧化铝晶粒长大后的晶粒形态特征及氢氧化铝的理论晶体生长习性.首先,用BFDH法说明了生长过程中最重要的面;其次,采用晶体平衡形态(Equilibrium morphology)法,用Morphology程序对氢氧化铝3×4×2超晶胞及其(001),(100),(010),(011),(110),(101)和(112)面真空slab模型进行平衡形态计算,计算结果与实验结果吻合,很好地预测了各显露面族(001),(100),(010),(011),(110),(101)和(112)面族.理论生长习性计算结果表明,氢氧化......
