U.v. photolysis of homogeneous solutions containing tetrakis(tetrabutylammonium)decatungstate(VI), [NBu4]4[W10O32], and olefins in acetonitrile leads to dimerization of olefins via abstraction of an allyl hydrogen, with accompanying formation of reduced decatungstates, up to two electrons. Coexistence of heterogeneous…

The core structure of hedgehog point disclinations in magnetic and nematic liquid crystal systems is investigated within Landau theory. Exact spherically symmetric solutions are found, with isotropic cores. In the nematic hedgehog the solution is uniaxial everywhere. Nematic hedgehogs are very much larger than magneti…

In Escherichia coli, a single operon encodes the metabolic and regulatory enzymes of the glyoxylate bypass. The metabolic enzymes, isocitrate lyase and malate synthase, are expressed from aceA and aceB, and the regulatory enzyme, isocitrate dehydrogenase kinase/phosphatase, is expressed from aceK. We cloned this opero…

Abstract Addition type imide resins are finding increased use as matrix resins for advanced composites. Many different chemical approaches have been used to synthesize imide resins which are easy to process (similar to epoxies) but higher in temperature resistance. This paper outlines recent advances in thermosetting…
