YbBa2Cu4O8(Yb124) films were prepared on SrTiO3(001) and SrTiO3(110) substrates by coating-pyrolysis process at ambient pressure, and the alignments of these films were investigated by XRD θ-2θ scanning and XRD pole-figure analysis. Films prepared on SrTiO3(001) consisted of almost single-phase [001]-oriented epitaxial Yb124. On the other hand, films on SrTiO3(110) consisted of [107]-oriented epitaxial Yb124 and other impurity phases, one of which was considered to be so-called “other perovskite” phase.

Asymmetric monobenzoylation reactions of cyclic meso-1,3- and 1,4-diols were catalyzed by a phosphinite derivative of quinidine to afford the corresponding monobenzoylated diol with good yield and enantioselectivity.

The effects of cold treatment on the cortical microtubules (MTs) of Chaetomorpha moniligera Kjellman were investigated by immunofluorescence microscopy. Cortical MTs in Chaetomorpha thallus are arranged longitudinally. In this study, 70–75% of MTs disassembled within 4 h on ice while the others remained stable under these conditions. Reticulate background immunofluorescence, assumed to indicate the presence of a tubulin monomer, was distributed about the stable MTs. Immunofluorescence was prominent in only 50% of the cells. Tubulin polymerization was noted where the background and MT immunofluorescence was strong. New MTs grew transversely as single strings or clusters from the sides of MTs after cold treatment for 4 h and elongated with time to take on a reticulate form at 24 h. The significance of this tubulin polymerization under cold treatment is discussed.
