Superconductivity and magnetism in niobium doped YBa2Cu3O7 Related high Tc ceramics

Magnetic characterization has been performed on the members of the cuprateniobate RBa₂Cu₂NbO₈ (R = Pr, Nd, and La) series and R_1.5Ce_0.5Sr₂Cu₂NbO₁₀ (R = Pr, Eu, Nd, and Sm) series. The PrBCNO samples show a signature in the magnetization of a magnetic ordering at 12K. The PrCSCNO sample is nonsuperconducting and shows two distinct orderings at 17K and 53K. No such magnetic phase transition is observed down to 2K in the Nd and La based RBCNO materials or the Nd, Sm, and Eu based RCSCNO materials. Measurements of the lower critical field curve, dc irreversibility line, and critical curent densities are reported for each of the superconducting NdCSCNO, SmCSCNO, and EuCSCNO compounds.     

含聚二甲基硅氧烷的聚醚聚氨酯膜透气性及表面性质研究

以聚二甲基硅氧烷（ＰＤＭＳ）／聚四氢呋喃（ＰＴＭＯ）为软段，４，４＇－二环己基甲烷二异氰酸酯（ＨＭＤＩ）为硬段（丁二醇ＢＤ为扩链剂）制成的多相嵌段共聚物作为基质材料，进行了气体（Ｏ２和Ｎ２）透过性试验，同时对膜材料进行了ＥＳＣＡ表面分析。结果表明，共聚物膜的透气性能取决于材料中连续相组分，随着软段中ＰＤＭＳ含量的改变而变化。当ＰＤＭＳ含量较高时，共聚物膜显示出ＰＤＭＳ均聚物的特性，具有较高的气体秀

Characterization and modification of fillers for paints and coatings

This paper highlights the possibility of inverse gas chromatography for the surface characterization of common fillers (CaCO₃, talc, SiO₂,) for paints and coatings. Divided solids are described, on the one hand, by the dispersive component of their surface energy and, on the other, by a specific parameter indicating their acid-base interaction potential. The role of the surface morphology at a molecular level is also examined. It is demonstrated that steric effects play an important role in the adsorption of probes on lamellar solids like talc. The consequences of surface treatments as well as examples of practical applications are also reported.
