A water molecular gel can be formed by the aggregation and self- assembly of gelator 4,4-bissteaiylarnide diphenyl ether at very low concentration. The microcosmic morphology, thin fiber-like structure, was observed from atomic force microscope and TEM of the gels.

通过原子力显微镜以及透射电子显微镜对水分子凝胶的微观形态进行了表征，表明凝胶因子可以在水中聚集、自组装成延伸的螺旋缠绕细纤维结构，并且得出了纤维束的平均直径在100nm左右，平均孔径在100nm左右。

And precipitation rate of vanadium was higher than 98.5%. Five vanadium catalysts were made withγ-Al_2O_3 and the mesoporous molecular sieve MCM-41 as carrier, and were made by dipping method, intermingle process and functionalizing method respectively. The characterization of their pore size, crystal structure, specific surface area and V_2O_5 load of catalysts were studied by XRD, the adsorption /desorption of N_2 technique, Raman spectroscopy and XRF. The activities of the catalysts estimated by the synthesis of DPC with DMC and phenol.
