铁酸镧超细粉末的制备

以La(NO3)3·6H2O、(NH4)2Fe(SO4)2和Fe2O3为原料,运用正交实验法确定最优实验条件,利用固-液界面法制备稀土铁酸盐超细粉末———铁酸镧.对产物进行部分物理测试,分别测定其全铁、亚铁离子含量,用扫描电子显微镜测定其形貌和粒径.结果表明,产物为均匀的圆球状纳米微粒,平均粒径76.0nm,反应中没有经过中间化合物,而是在固液界面上进行的.     

Cu（Ⅱ） effect on the conformation of regenerated silk fibroin in dilute aqueous solution

Much attention has been paid to the natural mechanism of silkworm spinning due to the impressive mechanical properties of the natural fibers. In this work, we studied the effect of Cu（Ⅱ） ions on the secondary structure of Bombyx mori regenerated silk fibroin （SF） in dilute solution by circular dichroism （CD）. The results indicate that a given amount of Cu（Ⅱ） induces the SF conformational transition from random coil to β-sheet, however, further addition of Cu（Ⅱ） is unfavorable for this conversion. Meanwhile, the conformational changes induced by Cu（Ⅱ） follow a nucleation-dependent aggregation mechanism, which is similar to that found in Prion protein （PrP） denaturation and Aβ-peptide aggregations, leading to the neurodegenerative disease. This work would help one understand further the natural spinning process of silkworm. Additionally, it would be significant for the study of the nervous system diseases, because silk fibroin, extracted in large amounts from Bombyx mori silkworm gland, could be a proper model to study PrP denaturation and Aβ-peptide aggregations.
