Much attention has been paid to the natural mechanism of silkworm spinning due to the impressive me-chanical 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 nuclea-tion-dependent aggregation mechanism, which is similar to that found in Prion protein (PrP) denaturation and Aβ-pep- tide aggregations, leading to the neurodegenerative disease. This work would help one understand further the natural spinning process of silkworm. Additionally, it would be sig-nificant 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 dena-turation and Aβ-peptide aggregations.

Low-expansion superalloys are susceptible to weld solidification cracks and heat,affected zone （HAZ）microflssures. To predict solidification cracking, QBasic procedures were developed and solidification reaction sequence, type, and amount of eutectic product were caiculated As manifested, primary solidification is followed by L→（Y＋ NbC） and L → （Y＋ Laves） eutectic reaction sequentially for G H903 and GH907; hence, the terminal eutectic constitue Y/Laves, While for GH909, intsare made up of Y/NbC and Y/only reaction L → （Y ＋ Laves） occurs and more Y/Laves eutectic forms. Therefore, GH909is more sensitive to solidification cracking. To predict HAZ liquation, cracking Visual FORTRAN procedures were developed, and constitutional liquation of NbC was simulated. As shown, solid dissolution of NbC prior to liquation decreases, and initial liquid film increases with the rate of thermal cycle. Higher rate of thermal cycle promotes the melting of the matrix adjacent to the liquid film and postpones the solidification of the at the eutectic n size and peak rifled indirectly by hot ductility tests.

We generalize Kupisewska method to the three-dimensional system and another derivation of the Casimir effect between two dielectric plates is presented based on the explicit quantization of the electromagnetic field in the presence of dielectricsl where the physical meaning of ＂evanescent mode＂ is discussed. The Lifshitz＇s formula is rederived using all the vacuum mode functions, which include the contribution of the ＇evanescent modes＇. Only in the case of the perfect, metallic plates will the evanescent modes become unimportant.

The influence of different contents of Cr, Mo, and rare earth element(RE) additives on the thermal conductivity of austenitic medium manganese steel was studied and discussed. The results show that the addition of Cr in medium manganese steel can improved the ordering of C–Mn atomic clusters, so as to improve the steel's thermal conductivity. However, Cr will lead to precipitation of a great deal of carbides in medium manganese steel when its content is greater than 4wt%. These carbides would aggregate around the grain boundary, and as a result, the thermal conductivity is decreased. By the addition of Mo whose content is about 2wt%, spherical carbides will be formed, thus improving the thermal conductivity of the medium manganese steel. The interaction between rare earth elements and alloying elements will raise both the thermal conductivity and the wear-resisting property of medium manganese steel.
